National Center For Human Genome Research

Letter of Intent Receipt Date:  October 15, 1990
Application Receipt Date:  December 3, 1990

The National Center for Human Genome Research (NCHGR)
invites applications for assistance awards to support
feasibility studies using advanced state-of-the-art DNA
sequencing technology to accomplish large-scale sequencing
projects at a higher rate and lower cost than is currently
possible.

This program is described in the Catalog of Federal Domestic
Assistance No. 13.172.  Awards will be made under the
authority of the Public Health Service Act, Sections 301
(Public Law 78-410, as amended 42 U.S.C. 241) and
administered under PHS grants policies and Federal
Regulations 42 CFR Part 52 and 45 CFR Part 74.  This program
is not subject to the intergovernmental review requirement
of Executive Order 12373 or to Health System Agency review.

BACKGROUND

The NCHGR sponsors basic and applied research concerned with
the development and application of new technologies for the
characterization and analysis of the human genome and the
genomes of important model organisms.  The activities
encompassed by the NCHGR program include genetic and
physical mapping, DNA sequencing, and informatics related to
mapping and sequencing.  The NCHGR, in conjunction with the
Department of Energy, recently formulated a five-year plan
that identifies areas where further research, including new
technology development, is needed before the
characterization of the human and other genomes can proceed
to the degree envisioned by the scientific community.

With respect to sequencing megabase regions of DNA, it is
clear that rates of sequence acquisition achievable today
must be increased at least 10- to 100-fold, and DNA
sequencing costs must be reduced at least 10-fold before
large-scale sequencing, on the order of a human chromosome,
can be considered.  Current technology for DNA sequencing
includes both manual and automated methods.  Sequencing DNA
by these methods is estimated to cost between $2 and $5
(total cost) per base pair.  However, currently available
sequencing techniques and strategies have not been tested on
a large scale.  Thus, it is possible that current or
improved methods, when used at the megabase level, and when
combined with economies of scale, new strategies, improved
automation, and/or new technologies, will significantly
lower the cost of DNA sequencing.  The purpose of this
Request for Applications (RFA)
is to support investigator-initiated research projects that
will extend the limits of advanced state-of-the-art
technology considerably further than has yet been attempted.

DEFINITION OF LARGE-SCALE SEQUENCING

The Program Advisory Committee on the Human Genome has
suggested that, at the present time, a reasonable definition
of a "large-scale sequencing project" is one that attempts
to determine on the order of three megabase pairs of
(largely) contiguous sequence in three years (by comparison,
the largest DNA sequence completed to date is a viral genome
of 240 kilobase pairs, work that took several years to
complete).  Continuity is an important characteristic of the
DNA sequence to be obtained;  the scientific problems that
arise in considering sequencing a one-megabase region are
different from those involved in sequencing 1000 one-
kilobase regions.  The Committee estimated that a rate of 2-
5 megabase pairs of DNA sequence per year in the subsequent
years should be attainable.  Similarly, reduction of the
cost of DNA sequencing to approximately $0.75 per base pair
within three years and to $0.50 per base pair within five
years was recommended to be a reasonable guide.  As these
levels are well beyond anything that has been achieved to
date, applicants are encouraged to consider them as
guidelines.   The NCHGR encourages discussion of these
guidelines by applicants, including an estimate of whether
they can be achieved.

DATA MANAGEMENT

Another essential component of DNA sequencing projects that
also needs to be investigated on a large scale is data
management.  Although software and database packages are
currently available for acquisition and assembly of DNA
sequence, they have been developed for relatively small-
scale applications.  Thus, it is not known whether any of
these will be adequate for use in megabase sequencing
projects.  It is understood that different sequencing
strategies will have different data handling needs and,
therefore, no one solution to data management problems for
large-scale sequencing is likely.

While, in the long run, software may have to be developed
for interpretation of the large segments of DNA sequence
generated by the human genome project, the informatics
priorities for this RFA will be primarily directed toward
the design, development, and testing of software for data
acquisition, assembly, and management.

RESEARCH SCOPE

Projects responsive to this RFA should test hypotheses and
new research strategies designed to yield information on the
feasibility of determining large amounts of DNA sequence
rapidly and in a cost-effective manner.  It is anticipated
that such projects will involve an integrated approach that
addresses a number of identifiable aspects of the problem,
including:

o The biological materials to be sequenced, e.g.,
genomic DNA or overlapping clones representing a
megabase-sized region.  Applicants are encouraged
to select DNA comprising regions of high
biological interest;

o Scale-up of DNA sequencing technology to allow
large-scale, high-throughput, and low-cost
acquisition of DNA sequence data.  Note: in order
to have a uniform approach for estimating the cost
of sequencing, applicants should calculate the
cost per base of finished DNA sequence ready for
publication and/or submission to a public
database.  The cost figure should include all
direct and indirect expenses, starting either
directly with the DNA of the organism  or with
appropriately large fragments (YAC or cosmid
clones) and ending with the final finished
sequence.  Neither the costs of any necessary
laboratory renovation nor the costs associated
with the interpretation of DNA sequence data
should be considered as a part of the per base
cost of sequence determination;

o Types of errors and rates of error that will occur
in large-scale DNA sequencing, and a discussion of
what level of error will be acceptable;

o Overall strategies, including quality control
systems, and plans for organizing the research
group;

o Systems for data acquisition, data management,
sequence assembly, and error estimation.

DATA RELEASE

The policy of the U.S. Public Health Service (PHS) states
that "when resources are developed with PHS funds and the
associated research findings have been published . . . it is
essential that they be made readily available for research
purposes to the scientific community."  Applicants will be
expected to follow this policy.  Generating large amounts of
DNA sequence will raise additional questions with respect to
data release and public accessibility to DNA sequence data
because much of this data will never be published in
journals or will not be published in its entirety.  The
NCHGR considers the timely release of data to the scientific
community to be critical and encourages applicants to
release all sequence data, including those that are not
published,  to a public database in a timely fashion.  This
is an area of active discussion within the scientific
community.  Although it will not be used as a review
criteria, the NCHGR is interested in the
investigator's analysis and evaluation of issues related to
the timely release of data, such as a timetable for data
release, the criteria for "finished" DNA sequence (i.e.,
sequence that is ready to be publicly released), and the
intervals (e.g., number of nucleotides or number of months)
at which data will be released.

MECHANISM OF SUPPORT

Support for this program will be through research grants
(R01s). Applicants may request up to five years of support.
For grants awarded for more than three years, competitive
renewals will be due at the end of the third year to allow a
determination of whether the project is satisfactorily
meeting its stated objectives.  As a result of that review,
funds may be continued at the level recommended or reduced
to phase out the project by the end of the original project
period.

An annual meeting is being planned to assist grantees receiving
funds under this RFA in maintaining communication with other
investigators working on the development of large-scale DNA
sequencing methods and in obtaining rapid access to those
developments.  Funds for
travel to this
meeting for as many as two investigators can be requested.

The total amount of support available for grants under this RFA
(approximately $6 million) is
contingent upon the appropriation of funds for this purpose.
It is anticipated that up to three awards will be made
during fiscal year 1991.  There is no set limit on the size
of each award.  Rather, each investigator should propose a
budget adequate to accomplish the work proposed.  The number
of awards is contingent
upon the quality of the applications received; if there are
a large number of meritorious applications, consideration
will be given to increasing the number of awards.  It is
possible that additional RFAs soliciting applications on
this topic may be published in the future.

LETTER OF INTENT

It is strongly recommended that potential applicants contact
NCHGR staff to discuss research objectives.  Potential
applicants are asked to submit a letter of intent by October
15, 1990.  This letter should include a descriptive title of
the proposed research, names of principal investigators and
other key investigators and their institutions.  The
letter of intent is requested in order to provide an
indication of the number and scope of applications to be
reviewed.  The letter of intent does not commit the sender
to submit an application, nor is it a requirement for
submission of an application.  Letters of intent should be
sent directly to:

Dr. Jane L. Peterson
Chief, Research Centers Branch
National Center for Human Genome Research

APPLICATION AND REVIEW PROCEDURES

Applications in response to this announcement will be
reviewed in accordance with the usual NIH peer review
procedures.  If the application submitted in response to
this RFA is substantially similar to a research grant
application already submitted to the NIH for review, but has
not yet been reviewed, the applicant will be asked to
withdraw either the pending application or the new one.
Simultaneous submission of identical applications will not
be allowed, nor will essentially identical applications be
reviewed by different review committees.  Therefore, an
application cannot be submitted in response to this RFA
which is essentially identical to one that has already been
reviewed.  This does not preclude the submission of
substantial revisions of applications already reviewed, but
such applications must include an Introduction addressing
the previous critique.

Applications will first be screened for responsiveness to
this RFA by NIH staff.  Those deemed nonresponsive will be
returned to the applicant.  If a large number of responsive
applications is received, they will undergo a preliminary
peer review to identify the most meritorious ones.
Applications that are deemed non-competitive by this peer
review will receive only a brief critique and will not be
reviewed further.  The remaining applications will be
reviewed for scientific and technical merit by an initial
review group (IRG) assembled by the Office of Scientific
Review, NCHGR.  A second level of review will be conducted
by a national advisory council.  Review criteria include the
following:

o Overall scientific and technical merit of the
research;

o The potential for the proposed work for
attaining the research objectives outlined in
this RFA;

o Training, experience, research competence,
and dedication of the investigator(s);

o Adequacy of available facilities;

o Provision for the protection of human
subjects and the humane care of animals; and

o Appropriateness of the requested budget for
the work proposed.

Applications should be submitted using the form PHS 398
(rev. 10/88).  The RFA label available in the revised
application kit MUST be affixed to the bottom of the face
page.  Failure to use this label could result in delayed
processing of the application such that it may not reach the
review committee in time for review.  Application kits are available in
the business or grants office at most academic or research
institutions, or from the Division of Research Grants,
National Institutes of Health.  Applications will be
accepted in accordance with the following schedule:

I.    BACKGROUND AND SUMMARY

 The Acquired Immune Deficiency Syndrome (AIDS) is a
 disease that destroys the body's capacity to defend itself
 against a variety of infections.  By April 1990, over
 132,000 cases of AIDS had been reported in the United
 States and more than 80,000 of these patients (61%) had
 died.  Recent projections indicate that between 850,000 to
 1,000,000 persons in the United States may already be
 infected with HIV, the infectious virus associated with
 AIDS. Opportunistic infections (OIs) are the pathologic
 consequence of AIDS; they are the most frequent causes of
 morbidity and mortality in AIDS patients.   OIs are the
 principal cause of hospitalization of HIV-infected
 individuals.  The estimated total medical costs of AIDS
 patients in the U.S.A. alone will be $21 billion by 1991.


Individuals infected with HIV are susceptible to a range of
protozoal, fungal, viral, and bacterial infections.  While
Pneumocystis carinii, Candida albicans, Toxoplasma gondii,
herpesvirus (CMV, HSV), and Mycobacterium avium are the most
frequently reported opportunistic pathogens, recent reports
indicate that Cryptococcus neoformans and Cryptosporidium
are also prevalent in AIDS patients.  The actual incidence
of OIs in HIV-infected individuals may
be higher than the reports would indicate as there are
inherent problems in diagnosing and recording these
infections.  The following is a brief description of major
pathogens, currently available therapies, and deficiencies in
the clinical management of OIs in AIDS patients.

 Pneumocystis carinii pneumonia (PCP) is the most serious
 infection in AIDS patients; between 60-80% of AIDS
 patients will develop this complication.  In the past,
 approximately 90% of untreated individuals died from this
 infection.  Recent studies, based on the phylogenetic
 analysis of Pneumocystis 16S-like-RNA, indicate it to be a
 member of the family of fungi.

 Trimethoprim/sulfamethoxazole (TMP/SMX) and parenteral
 pentamidine isethionate are the drugs that are used as
 initial therapy.  Particularly in AIDS patients, TMP/SMX
 treatment is associated with the development of
 hypersensitivity reactions and a high frequency of adverse
 reactions.  The Food and Drug Administration (FDA) has
 approved aerosolized pentamidine for prophylaxis of PCP.

 In the United States, 15 - 68% of the adult population are
 seropositive for Toxoplasma gondii antibodies.  In
 immunocompromised individuals, reactivation of the
 pathogen leads to encephalitis, which is fatal if
 untreated.  AIDS patients who are known to have antibodies
 to T. gondii are at significant risk for developing
 toxoplasmic encephalitis.  At least 30% of AIDS patients
 who are seropositive for T. gondii will ultimately develop
 the disease.  Current treatment is the combination of
 pyrimethamine and sulfadiazine.  However, the treatment is
 limited by toxicity and lack of efficacy against the
 latent cystic form of the parasite.  Thus, the relapse
 rate is high if therapy is discontinued.  Recent studies
 suggest that clindamycin, in combination with
 pyrimethamine, may be effective against cerebral
 toxoplasmosis in AIDS patients.

 Cryptosporidium can cause enterocolitis and diarrhea,
 malnutrition, and death in humans.  Some of the known
 antiprotozoal and antifungal agents, such as
 TMP/SMX, pentamidine, ketoconazole,
 and metronidazole, are ineffective against
 cryptosporidiosis.

 Fungal infections account for more than 50% of the
 opportunistic pathogens seen in AIDS patients.  Candida
 albicans is the most common pathogen (80% of fungal
 isolates).  Candida species often cause oral and
 pharyngeal thrush (mucosal candidiasis).  Esophagal
 candidiasis is also common, but disseminated infection is
 rare.  Cryptococcosis develops in 6 - 13% of patients with
 AIDS.  Recently, there has been an increase in the
 reported cases of disseminated histoplasmosis caused by
 Histoplasma capsulatum in patients with AIDS with a
 history of residence or travel in endemic areas.

 Current management of fungal infections in AIDS patients
 has many problems.  The diagnosis is often imprecise.  The
 most common therapy is amphotericin B (AMB); sometimes,
 parenteral AMB is administered in combination with
 5-flucytosine.  Oral azoles, such as ketoconazole and
 fluconazole, are currently under study in AIDS patients.
 AMB is toxic and continued therapy is often required.
 Some of the recent fungal isolates are not susceptible to
 AMB.  AMB is only partly effective against
 coccidioidomycosis.  Therefore, there is a need for more
 selective antifungal agents.

 Mycobacterium avium complex (MAC) is the most common cause
 of bacterial infection in AIDS patients.  It is an
 intracellular pathogen and is characteristically
 resistant to many antituberculosis agents except
 ethambutol.  Therefore, it is essential to identify
 antimycobacterial agents that can penetrate cells,
 particularly macrophages.  Other agents that are effective
 in vitro against MAC include ansamycin, clofazimine,
 cycloserine, amikacin, ethionamide, imipenem and
 ciprofloxacin.  Unfortunately, these agents are not
 bactericidal at concentrations achievable in plasma.
 Recent studies suggest that combinations of
 antimycobacterial agents with immunomodulators, such as
 tumor necrosis factor (TNF), may be useful for treatment
 of MAC infections.

Infection with human cytomegalovirus (HCMV), a member of the
herpesvirus group, represents a significant problem in AIDS
patients; it is considered to be the second most common
opportunistic infection in AIDS patients.  The most common
clinical manifestation in AIDS patients is retinitis.
Greater than 90% of individuals with AIDS are seropositive
for HCMV.  Recent reports indicate that HCMV might
contribute to the progression of AIDS.  Certain regulatory
genes of HCMV are capable of increasing HIV gene expression
by transactivation.  Ganciclovir (DHPG) has been shown to be
effective against HCMV infection.  The drug, however, has
some toxic side effects and requires continuous treatment.
Furthermore, HCMV strains resistant to DHPG have been
isolated from patients receiving the therapy for a prolonged
period of time.  There is clearly a need for more potent and
selective inhibitors to treat  HCMV-induced diseases.

In summary, most opportunistic infections in AIDS patients,
especially Pneumocystis pneumonia and cryptococcal
meningitis, are life threatening if diagnosis and treatment
are delayed.  Others, such as CMV, HSV, and Candida may
cause severe morbidity.  The management of OIs in AIDS
patients is often difficult and complicated for various
reasons:  (i) OIs are often present simultaneously with
other OIs; (ii) the pathogens may develop resistance to
conventional therapies; and (iii) the patients are more
susceptible to drug-related toxic reactions.  It is
important to recognize that most of the currently available
therapies against OIs in AIDS patients either lack efficacy
or have potentially serious side effects.  The severity and
long-term consequences of the opportunistic infections
underscore the need for more selective and potent
therapeutic agents against them.  In addition, there is a
crucial need for studies on prophylaxis and maintenance
therapy for control of persistent and latent infections.

 Six NCDDGs received awards in 1990.  Pathogenic organisms
 under study include P. carnii, T. gondii, Cryptosporidium,
 M. avium, C. albicans, and C. neoformans.  Research being
 pursued by these Groups include identification of unique
 molecular targets in opportunistic pathogens that are
 exploitable in discovering selective therapeutic agents;
 rational design of novel drugs; X-ray crystallography and
 protein structure; biochemistry and metabolism of drugs;
 animal model evaluation of potential therapies; molecular
 biology of opportunistic pathogens; and immunotherapies.

II.   OBJECTIVES AND SCOPE

 The major goal of this RFA is to stimulate research
 efforts leading to targeted discovery of agents effective
 in the treatment as well as prophylaxis of OIs in AIDS
 patients.  No clinical trials will be supported.  Research
 efforts may be directed, but are not restricted, towards
 controlling infections caused by the following pathogens:
 Toxoplasma gondii, Cryptosporidium spp., Pneumocystis
 carinii, pathogenic fungi (except Candida spp.),
 Mycobacterium avium, and HCMV.

 Research considered responsive to this RFA may include,
 but is not necessarily restricted to, the following:

 o    studies to identify and characterize molecular
      targets in opportunistic pathogens that may be
      exploited in discovering selective therapeutic
      agents;

 o    studies on the biochemical differences between the
      selected pathogen and host cells.  For example,
      isolation and characterization of certain key enzymes
      and identification of compounds that selectively
      inhibit the enzymes from the pathogen;

 o    molecular genetic studies to identify differences
      between the pathogens and mammalian cells; studies to
      exploit the differences to identify selective
      therapeutic agents;

 o    targeted synthesis of compounds that will selectively
      interact with specific molecular targets;

 o    establishment and utilization of in vitro assay
      systems (biochemical, biological) to identify active
      agents (synthetic chemicals and biologicals including
      natural products) that inhibit selected molecular
      functions;

o studies on natural and treatment-induced emergence of drug-
 resistant pathogens as it relates to targeted drug
 approach.

The above-mentioned areas of investigations are
representatives of future possibilities.  Investigators are
encouraged to explore other avenues to identify potential
therapeutic agents.

It is expected that no more than one Group each will be
funded for P. carinii and cytomegalovirus.  Projects or
cores with proposed animal model development or efficacy
testing in animal models must be integrated within the major
goal of targeted drug discovery and required to attain the
Group's objectives.  Funds for evaluation of new agents in
animal models will be withheld until compounds generated by
the Group are available for animal efficacy studies and be
limited to 25% effort of the Group.  NOTE:  Animal
component(s) may be requested by the NIAID to evaluate in
animal models compounds other than their own.  When this
occurs, and in the event that this has not already been
done, the necessary funds for evaluation will be released.
If proposed, studies on combination therapies should be
limited to 25% of total effort of the Group.  Projects
utilizing non-random screening of natural products,
biologics and/or synthetic compounds must not exceed 25% of
the total effort of the Group.  Large-scale random screening
of compounds will not be supported under this RFA.

 Studies required for the clinical development of
 identified potential treatments are beyond the scope of
 this RFA, but development through the private sector is
 encouraged.  Alternatively, an NCDDG may request that the
 NIAID assist in these developmental tasks.  The National
Institutes of Health (NIH) has a
 contract program for the preclinical development of
 compounds for the treatment of AIDS.  The NIAID has
 contracts for the evaluation of relevant therapies in
 several animal models.  In addition, the NIAID has awarded
 47 AIDS CLINICAL TREATMENT UNITS (ACTUs) for Phase I,
 Phase II, and Phase III clinical trials at 112 sites.  It
 is envisioned that these ACTU cooperative agreements will
 be available for clinical studies of treatments discovered
 under this initiative, upon the recommendation of the
 NCDDG and concurrence of the AIDS Clinical Drug
 Development Committee and the Division of AIDS.

III.  MECHANISM OF SUPPORT

 A.   Awards will be made as COOPERATIVE AGREEMENTS.
      NIAID, in awarding the Cooperative Agreement,
      anticipates substantial programmatic staff
      involvement during performance of the award.  The
      nature of NIAID staff assistance to the awardees is
      described in Section VIII of this RFA under "TERMS OF
      AWARD:  NATURE OF PARTICIPATION OF NIAID STAFF".
      There is no intent, real or implied, for NIH staff to
      direct Group activities or to limit the freedom of
      investigators.  The interaction of academic and non-
      profit research institutions with commercial
      (including industrial) organizations and Government
      is encouraged to favor the efficient invention of new
      entities and strategies for AIDS treatment and to
      facilitate their subsequent development to clinical
      trial.

 B.   NIAID has set aside $2.0 - 2.5 million for the
      initial year's funding of this RFA.  The amount spent
      will be dependent on the continuing availability of
      funds for this purpose and the quality and diversity
      of approved applications.  Funding of 3-4 awards is
      anticipated.  The dollar value of NCDDG awards is
      subject to the same limitation governing Program
      Project grants.  Current limit for a Program Project
      is one million dollars in total costs, unless prior
      approval by NIAID is obtained.  The starting date for
      the initial annual period will be on or after June 1,
      1991.

      [When the applicant institution is outside the United
      States, awards will be limited to three years.  When
      the applicant institution is within the United States
      and the application contains research projects in a
      foreign country, the request for funding may be up to
      five years.]

 C.   Awards will be made to successfully competing Groups
      rather than to the individual scientists or
      institutions comprising the Group.  Support of all
      Group activities will be coordinated through a
      Central Operations
      Office located within the applicant organization.
      Each award will be made only to the Principal
      Investigator's institution.

 D.   Under the Cooperative Agreement, a partner
      relationship between the recipient of the award and
      NIAID exists in which the Group is responsive to the
      requirements and conditions set forth in this RFA.
      Specifically, the Principal Investigator defines the
      details for the project within the guidelines of the
      RFA, retains primary responsibility for the
      performance of the scientific activity, and agrees to
      accept close assistance in coordination, cooperation,
      and participation of NIAID staff in all aspects of
      scientific and technical management of the project in
      accordance with the terms formally and mutually
      agreed upon prior to the award.  It is presently
      envisioned that the NIAID will be actively engaged in
      the coordination of all components including
      assisting the awardees in:

            *   cooperative participation in data analysis
                and reporting;

            *   prior approval of changes of key personnel
                including the Principal Investigator or
                Project Leaders;

            *   retention of the option to withhold support
                if a Project Leader withdraws from the
                Group and a suitable replacement of key
                personnel is not obtained.

 E.   All policies and requirements that govern the grant
      program of the U.S. Public Health Service and the
      NIH apply.

 F.   Although this program is provided for in the
      financial plans of NIAID, the award of Cooperative
      Agreements pursuant to this RFA is also contingent
      upon the continuing availability of funds for this
      purpose.

IV.   DEFINITIONS

 ARBITRATION PANEL - A group composed of the Principal
 Investigator or Project Leader of a particular NCDDG as
 the "Group" designee, one NIAID designee, and a third
 designee with expertise in the relevant area and chosen by
 the other two.  The interaction of this panel is detailed
 in Section VIII, "TERMS OF AWARD".

 COOPERATIVE AGREEMENT - An assistance mechanism in which
 substantial NIAID programmatic involvement with the
 recipient organization during the performance of the
 planned activity is anticipated.

 CORE COMPONENT - Laboratory facilities for equipment and
 services that shall be shared by two or more projects of
 the NCDDG.  Examples of core components are:  biochemical
 studies, screening studies, scale-up synthesis of drugs
 (ten grams or less).  The core can be defined as any
 project with established techniques and assays which
 perform a service function or results in an economy of
 effort and savings in the overall costs of the NCDDG.

 DISCOVERY - The term "discovery" is used explicitly to
 limit activities of the NCDDG to preclinical
 identification, design, and development of new entities.

 INVENTION - A new drug or innovative treatment that is or
 may be patentable under Title 35 of the United States
 Code.

 NATIONAL COOPERATIVE DRUG DISCOVERY GROUP (NCDDG) - In
 this RFA the terms NATIONAL COOPERATIVE DRUG DISCOVERY
 GROUP, NCDDG, and "Group" are synonymous.  A number of
 laboratory research projects representing diverse
 scientific disciplines and organizations that join
 together under a single Principal Investigator and that
 function as a unit with a common goal:  the
 conceptualization, invention, and evaluation of new
 entities and strategies for the treatment of OIs.  Groups
 must consist of at least two independent Projects
 conducted by at least two independent laboratories.  A
 CORE COMPONENT cannot be used toward fulfillment of the
 two Projects requirement.

 NEW DRUG - In the context of the NCDDG-OI program, the
 term "drug" is used broadly to encompass new synthetic
 agents, natural and biological products as novel
 therapeutic strategies or inventions designed to
 effectively treat OIs in AIDS patients.

 NIAID NCDDG PROGRAM DIRECTOR - A member of the NIAID
 extramural staff who coordinates NIAID's participation in
 the NCDDG Program.  This responsibility includes: (i)
 overseeing the entire NCDDG-OI program; (ii) assuring that
 Groups' objectives are consistent with Program's and NIAID
 mission and goals; (iii) assigning Scientific Coordinators
 to appropriate Groups based on scientific expertise and
 compatibility with the Group research interests; (iv)
 assuring overall scientific balance among Groups in the
 NCDDG Program; (v) networking and facilitating
 collaboration between Groups and industry to expedite
 development of promising anti-OI agents; (vi) keeping the
 NCDDG Program current with regard to scientific
 developments and breakthroughs; and (vii) identifying gaps
 not adequately pursued.

 NIAID SCIENTIFIC COORDINATOR - A member of the extramural
 staff of the NIAID who functions as a peer with the
 Principal Investigator and Project Leaders and facilitates
 the partnership relationship between NIAID and the Group.
 The Scientific Coordinator, based on his/hers scientific
 expertise, interests, and compatibility with the Group's
 areas of research, is assigned to the Group by the NCDDG
 Program Director.

 PRINCIPAL INVESTIGATOR - The person who assembles the
 NCDDG, assembles a single application with the information
 provided by the Project Leaders, submits the
 application in response to this RF,A and is responsible
 for the performance of the Group as a whole and each of
 the Project Leaders.  The Principal Investigator is very
 strongly encouraged to lead one of the research projects
 of the Group and is expected to coordinate Group
 activities scientifically and administratively.  The
 Principal Investigator's (awardee) institution establishes
 and operates the Central Operations Office that funds
 Group members and is legally and fiscally accountable for
 the disposition of funds awarded.

 PROJECT LEADER - The leader of one of the scientific
 research projects of the NCDDG.

 SCIENTIFIC ADVISORS PANEL - A panel, comprised of the
 Scientific Coordinator and 2-3 peers from the scientific
 community, whose mission is to provide the Principal
 Investigator with a comprehensive review of the Group's
 activities and progress, consult on future goals and
 strategies, and recommend alternative directions, as
 appropriate.   Selection and appointment of the Panel is
 the responsibility of the Principal Investigator.  Members
 of the Panel will not be affiliated with any of the
 institutions comprising the Group.  A Scientific Advisors
 Panel is required only of Groups funded for more than
 three years.  The composition of the designated Panel will
 be provided to the NIAID in the Noncompetitive Renewal
 Application at the completion of year two of funding.  The
 Panel will provide the Principal Investigator a
 comprehensive review of the Group's activity in years three
 and four of funding.  These reviews will encompass
 timeliness of progress in individual projects relative to
 original projections; progress relative to Group's
 objectives and needs; continued relevance of a given
 project to Group's goals; continued coordination of
 Group's objectives with the objectives of the NCDDG
 Program; and recommendations for new directions, as
 appropriate.

V.    COMPOSITION OF AN NCDDG-OI

 A.   The NCDDG-OI will consist of the following:

      1.    A Principal Investigator;

      2.    Project Leaders, each to head a research
            project.  The research projects will utilize
            diverse scientific disciplines or alternative
            disciplines that are appropriate to the
            realization of Group objectives (e.g.,
            microbiology, biochemistry, humoral immunology,
            cellular immunology, structural biology,
            biophysics, biochemistry, medicinal chemistry,
            organic chemistry, etc.).   Interdisciplinary
            projects are encouraged;

      3.    A Scientific Coordinator designated from the
            NIAID extramural staff;

      4.    (OPTIONAL) Core components that would provide
            for laboratory facilities, equipment, and
            services to be shared by two or more projects.
            It may also include support for the costs of
            administration, purchasing, and secretarial
            services.  Items described above that are
            included in the institution's indirect cost
            rate are subject to negotiations, based on
            their applicability as direct or indirect
            charges;

      5.    A Scientific Advisors Panel to be designated at
            the end of year two of funding by Groups funded
            for more than three years (see Section IV,
            "DEFINITIONS: SCIENTIFIC ADVISORS PANEL").  The
            Panel will work together with the Group,
            evaluate and advise on Group's progress, future
            goals, strategies, and new directions, as
            appropriate.  With the exception of the
            Scientific Coordinator, members in the Panel
            will not be affiliated with any of the
            institutions comprising the Group.

 B.   The Principal Investigator, in addition to providing
      scientific and administrative leadership, may have a
      research project.  Project Leaders will be directly
      responsible to the Principal Investigator.  The
      formation of the Group, the application in response
      to this RFA, the overall management of the Group, and
      the allocation of funds to the various laboratory
      projects will be the responsibility of the Principal
      Investigator and the Principal Investigator's
      institution in accordance with PHS policies.

 C.   The composition of the Group and its research
      projects should depend on the talents required to
      accomplish its scientific and technical objectives as
      perceived by the Principal Investigator and Project
      Leaders.  The major consideration in structuring an
      NCDDG should be the mobilization of maximum
      intellectual strength and the ability to carry out
      the proposed research.

 D.   An individual scientist may be proposed as a Project
      Leader by more than one applicant as part of a CORE
      COMPONENT.  Project Leaders who do not have a core
      function will not be supported by more than one
      Cooperative Agreement awarded under this RFA unless
      the research is clearly delineated in separate NCDDG
      applications.  Individuals currently supported under
      an existing NCDDG-OI or other NCDDG programs may be
      funded under this RFA as long as there is no
      scientific or budgetary overlap in funded activities.

 E.   An NCDDG may have more than one project from one
      institution.  However, the varied talents and
      commitment required for effective drug discovery are
      not usually all present in one institution, and it is
      anticipated that the Project Leaders within a Group
      will be from several institutions.

 F.   A minimum of two but no maximum number of research
      projects per Group is stipulated.  However, the
      Principal Investigator could experience difficulty in
      providing the desirable level of guidance and Project
      Leaders might communicate and collaborate less
      efficiently if the Group were to contain more than
      five or six research projects, including the
      Principal Investigator's project.

 G.   In forming Groups, Principal Investigators should
      remain cognizant of the need for communication,
      including regular meetings of the members.  While it
      is not a requirement of this RFA, the formation of
      Groups on a geographically regional basis may be
      advantageous.  This is a particularly important
      factor to be considered by applicants from outside
      the United States or if the applicant proposes
      laboratory projects in foreign countries.

 H.   An NCDDG is encouraged to include scientists from
      academia, non-profit institutions, and/or commercial
      organizations.  The active participation of industry
      is encouraged because it will allow this sector of
      the scientific community to contribute its
      intellectual and material resources and will favor
      expeditious development of effective anti-OI
      therapies.

VI.   RESEARCH GOALS AND SCOPE

 A.   The goals of the NCDDG-OI
      are:

      1.    The conceptualization, discovery and
            preclinical development of drugs and strategies
            designed to effectively treat OIs in
            individuals infected with the human
            immunodeficiency virus;

      2.    The conduct of biological, biochemical, and
            pharmacological studies leading to selection of
            potential therapies; and

      3.    The recommendation of therapies, entities, or
            strategies for development in clinical trials.

 B.   Applications for an NCDDG-OI should stress creative
      approaches to the discovery of effective therapies to
      treat OIs and should emphasize
      the following:

      1.    specific objectives of the proposed NCDDG-OI;

      2.    research approaches to the realization of
            objectives and the provision of comprehensive
            information (including citations) in support of
            the rationale(s) for the proposed approaches;
            and

      3.    the scientific and technical areas of expertise
            (Project Leaders) required to attain Group
            objectives and the leadership ability of the
            Principal Investigator.

 C.   The Group's objectives and goals should be relevant
      and compatible with NIAID Program's missions and
      directions as stated in this RFA.

VII.  PATENT COVERAGE

 Since the discovery of agents active against OIs in AIDS
 patients is the objective of this effort, and since active
 involvement by industrial laboratories is facilitated by
 the existence of adequate patent coverage, it is essential
 that applicants provide plans to assure such coverage.
 With multiple institutions involved, the patent situation
 could be complicated.  Each applicant Group must,
 therefore, provide a detailed description of the approach
 to be used for obtaining patent coverage and for licensing
 where appropriate, in particular where the invention may
 involve investigators from more than one institution.  In
 addition each Group must provide a detailed description of
 the procedures to be followed for the resolution of legal
 problems that may develop.  All Group members can be full
 partners in the research and in any inventions resulting
 therefrom.  The specific patenting arrangements among the
 institutions may vary, and could include joint patent
 ownership and exclusive licensing arrangements.
 Applicants are encouraged to develop an arrangement that
 is most suitable for their own particular circumstances.

 The proposed patent plan among the institutions comprising
 the group MUST be included along with the application.
 The patent agreement, signed and dated by the
 organizational officials authorized to enter into patent
 arrangements for each Group member and member institution,
 must be sent before the application deadline to Dr.
 Margaret I. Johnston, Chief, Developmental Therapeutics
 Branch, Division of AIDS, 6003 Executive Boulevard,
 National Institutes of Health, Bethesda, MD  20892.

 Federal regulation clause 37CFR401 and HHS Inventions
 regulations at 45 CFR Parts 6 and 8 require that NIH be
 informed of inventions and licensing occurring under NIH-
 funded research.  Invention and licensing reports must be
 submitted to Extramural Invention Reports Office, Office
 of Extramural Research, Building 31, Room 5B41, NIH, with
 a copy to Dr. Margaret I. Johnston, Chief, Developmental
 Therapeutics Branch, Division of AIDS.

VIII. TERMS OF AWARD:  AWARDEE RIGHTS AND RESPONSIBILITIES
      AND NATURE OF NIAID PARTICIPATION

 Assistance via a Cooperative Agreement differs from the
 traditional research grant in that, in addition to the
 normal programmatic and administrative stewardship
 responsibilities, the component awarding the Cooperative
 Agreement anticipates substantial programmatic involvement
 during performance of the project.  However, the applying
 Group must define its objectives and approaches in accord
 with its own interests and perceptions of novel and
 exploitable approaches to the discovery of effective
 agents active against OIs in AIDS patients and must
 develop the details of the research design following the
 guidance given in this RFA.  It is the primary
 responsibility of the Principal Investigator to clearly
 state the objectives and approaches of the Group, to plan
 and conduct the research stipulated in the proposal, and to
 ensure that the results obtained are analyzed and
 published in a timely manner.  The data obtained will be
 the property of the awardee.

 NIAID shall participate as a member of the Group and shall
 be represented by a Scientific Coordinator.  The
 Coordinator shall be selected from the Developmental
 Therapeutics Branch of the Division of AIDS and appropriate Branches
 of the Division of Microbiology and Infectious Diseases of
 the NIAID.

 During performance of the award the NIAID Scientific
 Coordinator may provide appropriate assistance by
 participating in the design of group activities; advising
 in the selection of sources or resources, replacement of
 staff, etc.; coordinating or participating in collection
 and/or analysis of data; advising in management and
 technical performance; or participating in the preparation
 of publications.  However, the role of NIAID will be to
 facilitate and not to direct the activities.  It is
 anticipated that decisions in all activities outlined
 below will be reached by consensus of the Group and that
 the NIAID Scientific Coordinator will be given the
 opportunity to offer input to this process.  The manner of
 reaching this consensus and the final decision-making
 authority will rest with the Principal Investigator.

 Failure to abide by these Terms of Award may result in
 withholding of funds by the NIAID.

A.    Awardee Rights and Responsibilities

      1.    The Principal Investigator, Project Leaders,
            and the NIAID Scientific Coordinator will meet
            periodically to review progress, plan and
            design research activities, and establish
            priorities.  The frequency of meetings (not
            less than two per year) shall be determined by
            the Principal Investigator who will be
            responsible for scheduling the time and place
            (generally at one of the performance sites),
            notifying the Scientific Coordinator at least
            forty-five days prior to the meeting date, and
            preparing concise proceedings or minutes which
            will be delivered to the members of the Group
            including the Scientific Coordinator within
            thirty days of the meeting.  The NIAID
            Scientific Coordinator will participate but not
            chair Group meetings.

      2.    In addition to these two meetings, one meeting
            each year will be held at the NIH Bethesda (or
            at a site designated by NIAID) during which all
            Principal Investigators and Project Leaders
            will present significant findings in symposium
            format.

            The NCDDG annual meeting is one of the central
            points for information flow among the Principal
            Investigators, NCDDG Program Director, the
            private sector, other drug development
            concerns, and NIAID.  The Program Director
            consults with the Groups' key personnel in
            formulating the overall agenda, selecting
            session Chairs, and in identifying key topics
            for discussion.  Session Chairs select the
            workshop participants who constitute the bulk
            of invited speakers.  This forum is central for
            cross-fertilization of ideas, integration of
            unique anti-HIV strategies, and a critical
            source for updating Program and keeping it
            abreast of scientific and technological
            innovation toward the discovery of new anti-
            viral modalities.  Data presented at this
            meeting are selected by the individual
            presenters in consultation with their Principal
            Investigator thus affording appropriate
            protection of proprietary or commercially
            sensitive information.

            It is expected that selected NIH staff, members
            of established committees and advisory boards,
            and others active in the process of discovery
            and development of therapies for opportunistic
            infections will be invited to this meeting.
            The Principal Investigator will have control
            over the data and results presented by the
            Group.  Funds for attendance of these three
            required meetings should be included in the
            budget for each research project.  The
            application should also include plans for
            scheduling Group meetings, notifying Group
            members including the NIAID Scientific
            Coordinator, and documenting and disseminating
            Group meeting proceedings.

      3.    Groups funded for more than three years will
            designate a Scientific Advisors Panel by the
            end of year two of funding.  The Principal
            Investigator will convene a meeting or meetings
            with the Panel in years two and three of funding.
            The Panel will work together with the Group
            and advise the Principal Investigator on the
            Group's progress, future goals, strategies and
            new directions, as appropriate.  Members of the
            Panel will not be affiliated with any of the
            institutions comprising the Group.  Funds to
            cover expenses incurred by the Panel should be
            included in the Administrative Core component
            of the application.

      4.    A critical determinant of Group success will be
            the degree of communication among its members.
            Therefore, additional informal meetings among
            all participants, as well as regular telephone
            and written communication, will be important.

 B.   NIAID Assistance in Implementation and Management of
      Research Activities

      1.    The NIAID Scientific Coordinator, like other
            Group members, may suggest studies within the
            scope of the Group's objectives and research
            activities; may present to the Group
            experimental findings from published sources or
            from contract projects in support of these
            suggestions; may participate in the design and
            execution of experiments as agreed to by the
            Group; and may participate in the analysis and
            publication of results.

      2.    The NIAID Scientific Coordinator may assist the
            Group or other individual members in research
            planning, particularly with respect to:

            a.  reduction of duplication of efforts
                conducted in other extramural projects;

            b.  provision of needed resources and
                information that may not be otherwise
                available to the Group; and

            c.  provision of data from testing conducted in
                resource contract laboratories.

      3.    The Scientific Coordinator may serve as a
            resource for information, laboratory testing,
            and biological supplies (e.g., animals), when
            such resources are not a normal requirement of
            the Group's day-to-day research activities but
            may be required on an occasional basis.  The
            following is a list of some resources that
            may be available from the NIAID:  these
            resources are intended for initial studies and
            will not be available on a continual basis.

         (i) Reference compounds for standardization of
             test systems, as analytical standards, and for
             related purposes.

         (ii) Materials for biological testing.

         (iii)    Laboratory testing capacity, whenever
                  appropriate and possible, in a current
                  contract-based preclinical therapy-
                  related laboratory testing program or
                  other NCDDGs.  The Groups are expected to
                  provide sufficient test material for such
                  testing.

         (iv) Searches of computer files of chemical
             structures and biological activity, if
             requests for such searches are sufficiently
             focused to avoid excessive costs.  Information
             given to an NCDDG will be restricted by the
             standard confidentiality agreements between
             the Government and suppliers of test materials
             to the Government.

         (v) Experimental animals, when the occasional need
             arises in Groups whose main research
             activities do not require these materials on a
             regular basis.  Groups whose experimental
             approach involves studies that require animals
             on a regular basis must budget for costs to be
             paid from award funding.

         (vi) Computer processing and statistical
             evaluations, if costs are not excessive.

         (vii)    Networking with other NIH staff, NCDDGs,
                  other collaborators, and other government
                  and non-government employees who may
                  provide guidance, expertise, or resources
                  to facilitate development of therapies
                  identified by the Group.

             It is understood that the Government provides
             its consulting and testing services in the
             interest of promoting experimental anti-
             infective agents through preclinical and
             clinical testing and development in the most
             expeditious fashion, and that newly marketed
             agents that have utilized this service will be
             offered to the public at a reasonable cost.

      4.     The NIAID Scientific Coordinator may assist
             the Groups by providing them with compounds
             for initial testing and for confirmatory
             testing.  In testing compounds supplied by the
             NIAID, the Groups agree to abide by any
             confidentiality agreement between the NIAID
             and a third party who has supplied the
             compounds for testing through NIAID.

C.    Collection and Analysis of Data, Procedures for
      Submission of Results to NIAID, and Preparation of
      Group Findings for Presentation and Publication

      In addition to the special reports and stipulations
      described below, reporting requirements will be
      identical to those currently in existence for awardees
      of traditional NIH research project grants.

      1.     The principal end product of NCDDG-OI
             activities will be the discovery of new
             entities and strategies for development to
             clinical trials for AIDS-associated OIs.
             Subsequent developmental work through private
             resources is encouraged.  Alternatively, the
             Group may recommend that development be
             sponsored by NIAID.  In the latter case, it
             will be necessary for the Principal
             Investigator, appropriate Project Leaders, and
             NIAID to collaborate in the analysis,
             summarization, preparation, and presentation
             of data to the appropriate NIAID staff.

      2.     NIAID will retain the option to cross-file or
             independently file an application for
             investigational clinical trial; e.g., an
             Investigational New Drug application (INDA) to
             the United States Food and Drug Administration
             of any invention resulting from these NIAID-
             supported Cooperative Agreements.  Reports of
             data generated by the Group or any of its
             members required for inclusion in INDAs and
             Clinical Brochures and for cross-filing
             purposes will be submitted by the Principal
             Investigator to the Scientific Coordinator
             upon request.  Such reports will be in final
             draft form and include background information,
             methods, results, and conclusions.  They will
             be subject to approval and revision by NIAID
             and may be augmented with test results from
             other Government-sponsored projects prior to
             submission to the appropriate regulatory
             agency.

      3.     The Government, via the Program Director or
             designated Scientific Coordinator, will have
             access to data generated under this
             Cooperative Agreement and may periodically
             review the data and progress reports.
             Information obtained from the data may be used
             by the Scientific Coordinator for the
             preparation of internal reports on the Group's
             activities.  However, the applicant will
             retain rights to the data, and timely
             publication of major findings is encouraged.
             Publication or oral presentation of work done
             under this agreement is the responsibility of
             the Principal Investigator and appropriate
             Project Leaders and will require appropriate
             acknowledgement of NIAID support.

D.    Inasmuch as certain activities under "TERMS of AWARD:
      NATURE OF PARTICIPATION OF NIAID STAFF" require
      approval by NIAID staff during performance of this
      Cooperative Agreement (specifically, reports intended
      for inclusion in INDAs and Clinical Brochures, change
      in Principal Investigator or Program Leader,
      redistribution of biological materials received
      through the Scientific Coordinator and dissemination
      of research findings resulting from the use of these
      materials), NIAID will establish an arbitration
      process to resolve any differences of opinion with
      regard to programmatic matter.  An arbitration panel,
      composed of one Group designee, one NIAID designee,
      and a third designee with expertise in the relevant
      area and chosen by the other two, will be formed to
      review any scientific or programmatic issue that is
      significantly restricting progress.  This arbitration
      process in no way affects the right of an award
      recipient to appeal selected post award administrative
      decisions in accordance with HHS, PHS, and NIH
      regulations and policies.  These special arbitration
      procedures in no way affect the awardee's right to
      appeal an adverse action in accordance with PHS
      regulations at 42 CFR Part 50, Subpart D, and HHS
      regulations at 45 CFR Part 16.

E.    The special "TERMS OF AWARD:  NATURE OF PARTICIPATION
      OF NIAID STAFF" described in this section are in
      addition to, and not in lieu of, otherwise applicable
      OMB administrative guidelines, HHS Grant
      Administration Regulations at 45 CFR Part 74, and
      other HHS, PHS, and NIH grant administration policy
      statements.

X. REVIEW METHOD AND PERR REVIEW CRITERIA

      APPLICATIONS NOT RECEIVED AS A SINGLE
      PACKAGE FROM THE PRINCIPAL INVESTIGATOR AND THAT DO
      NOT CONFORM TO THE INSTRUCTIONS CONTAINED IN PHS 398
      (rev. 10/88 or 9/89) APPLICATION KIT  WILL BE JUDGED
      NON-RESPONSIVE AND WILL BE RETURNED TO THE APPLICANT.

      Applications will be reviewed by NIAID staff to
      determine administrative and programmatic
      responsiveness to this RFA; those judged to be non-
      responsive will be returned to the applicant without
      review.

      Those applications that are complete and responsive
      may be subjected to a triage by an NIAID peer review
      group to determine their scientific merit relative to
      the other applications received in response to this
      RFA.  The NIAID will withdraw from competition those
      applications judged to be noncompetitive for award and
      will notify the applicant Principal Investigator and
      institutional business official.

      Those applications judged to be competitive for award
      will be further reviewed for scientific and technical
      merit by a Review Committee convened by the Division
      of Extramural Activities, NIAID, during February 1991.
      The final level of review will be provided by the
      National Advisory Allergy and Infectious Diseases
      Council.

      REVIEW PROCEDURES AND CRITERIA

      Applications will be reviewed in the AIDS Review
      Section, NIAID, by an appropriate committee.  The
      application must be directed towards the attainment of
      the stated programmatic goals (see Section VI,
      "RESEARCH GOALS AND SCOPE").  The following factors
      will be considered in the scientific and technical
      review of the application:

      A.     Relevance of applicant's (Group) objectives to
             the discovery of new entities and strategies
             for the treatment of OIs in AIDS patients;

      B.     Scientific and technical significance,
             originality, and uniqueness of proposed
             research;

      C.     Scientific merit of approaches to realization
             of objectives;

      D.     Relevance and compatibility of Group's
             objectives with NIAID Program's missions and
             directions;

      E.     Specific competencies of the Principal
             Investigator and Project Leaders to conduct

             Investigator, Project Leaders, and other key
             personnel.  While there is no maximum percent
             effort set, it is anticipated that, due to the
             complexity and time required to maintain a
             well-coordinated and productive research
             effort, a 20% effort by the Principal
             Investigator and each Project Leader should be
             devoted to the study, unless there is
             compelling evidence to the contrary.

      F.     Likelihood that new potential therapy will be
             identified during the course of the proposed
             study;

      G.     Technical merit of proposed methods for
             producing or obtaining test materials and for
             their evaluation;

      H.     Technical sufficiency of methods for
             evaluation of new discoveries, laboratory test
             systems, models, etc.;

      I.     Administrative experience and competence of the
             Principal Investigator in the development,
             implementation, and management of
             comprehensive research programs;

      J.     Plans for effective intra-Group communication
             and for assuring Group cohesiveness;

      K.     Adequacy of existing physical facilities and
             resources of the Principal Investigator and
             Project Leaders including biohazard
             containment facilities as stipulated in
             Section IX, "MINIMUM REQUIREMENTS FOR
             APPLICATION," Part H;

      L.     Documented commitment of institutions
             represented by Group members; documented
             capability of Principal Investigator's
             institution to serve as Central Operations
             Office for the Group;

      M.     Commitment to accept the assistance of NIAID
             staff in accordance with the guidelines
             outlined under Section VIII, "TERMS OF AWARD;
             NATURE OF PARTICIPATION OF NIAID STAFF;"

      N.     Mechanism for selecting and replacing key
             professional or technical personnel using the
             framework of the RFA;

      O.     Ability of the Principal Investigator and
             Project Leaders to devote adequate time to the
             effective conduct of the study;

      P.     Conformance to "MINIMUM REQUIREMENTS FOR
             APPLICATION" (Section IX);

      Q.     Reasonableness of cost.

             Modifications of Form PHS-398 (rev. 10/88 or
             9/89)

             This RFA requires the submission of a single
             application for the proposed NCDDG.
             Because of
             the multi-institutional nature of an NCDDG and
             the special requirements in this RFA,
             additional instructions regarding format are
             contained in the NIAID Program and Project
             Information Brochure.

             The special requirements of this RFA will also
             necessitate the following modification.  The
             Introductory Section should apply to the
             proposed NCDDG as a whole with respect to
             goals, objectives, and overall research plan.

             The Introductory Section, not to exceed two
             pages, should contain any additional
             information about the proposed Principal
             Investigator or his/her institution as
             evidence of capability to carry out the
             scientific and administrative duties required
             in this RFA and the functions of the Central
             Operations Office.

             In addition, the Introductory Section must
