PURPOSE

The purpose of this Request for Applications (RFA) is to encourage
clinical testing of innovative and non-traditional pharmacotherapies
for treatment of cocaine/psychostimulant (amphetamines) dependence.
Two types of medications will be considered:  (1) traditional
pharmacotherapies addressing novel neurochemical mechanisms (beyond
classical biogenic amines or compounds previously extensively
tested); (2) non-traditional (alternative) pharmacotherapies selected
to restore brain homeostasis or to repair/compensate for existing
neurological/neurochemical deficits in chronic psychostimulant
abusers (e.g., special nutritional factors, amino acids,
neurotransmitter precursors, hormones, antihormones, supplements,
etc.).  Special emphasis will be put on testing natural compounds
with very low or no toxicity, which could be potentially also
utilized for treatment of children and pregnant women.

Investigators should study the safety and efficacy of novel
medications in either relapse prevention in detoxified
cocaine/psychostimulant dependent participants or reduction of drug
use.  The primary focus will be on relapse prevention.  Applications
will be also required to assess the impact of investigational agent
on HIV risk behaviors.  Applications that propose to evaluate
compounds already extensively studied in psychostimulant dependence
(traditional medications that act at dopamine, noradrenaline, or
serotonin systems, or carbamazepine, etc.) will not be considered
responsive.

HEALTHY PEOPLE 2000

The Public Health Service (PHS) is committed to achieving the health
promotion and disease prevention objectives of Healthy People 2000, a
PHS-led national activity for setting priority areas.  This RFA,
Novel Pharmacotherapies for Cocaine and Other Psychostimulant
Dependence, is related to the priority areas of alcohol and other
drugs.  Potential applicants may obtain a copy of Healthy People 2000
(Full Report:  Stock No. 017-001-00474-0 or Summary Report:  Stock
No. 017-001-00473-1) through the Superintendent of Documents,
Government Printing Office, Washington, DC 20402-9325 (telephone
202-512-1800).

ELIGIBILITY REQUIREMENTS

Applications may be submitted by domestic, for-profit and non-profit
organizations, public and private, such as universities, colleges,
hospitals, laboratories, units of State or local governments, and
eligible agencies of the Federal Government.  Racial/ethnic minority
individuals, women and persons with disabilities are encouraged to
apply as principal investigators.  Foreign institutions are not
eligible for the First Independent Research Support and Transition
(FIRST) award (R29).

International collaborative studies, which must include a U.S.
principal investigator, will also be considered.  For example, if the
investigational compound is not available on the U.S. market, but is
available in European or Asian pharmacopeias, the pilot studies may
be conducted in a foreign country.

MECHANISM OF SUPPORT

This RFA will use the National Institutes of Health (NIH) research
project grant (R01), FIRST (29) award, exploratory/developmental
grant (R21), and small grant (R03).  Research grants are awarded to
institutions on behalf of Principal Investigators who have designed
and will direct a specific project or set of projects.

Because the small grants and FIRST awards have special eligibility
requirements, application formats, and review criteria, applicants
are strongly encouraged to consult with the program staff (listed
under INQUIRIES) and to obtain the appropriate additional
guidelines/announcements for those grant mechanisms.

FUNDS AVAILABLE

It is anticipated that approximately $4 million will be available to
support projects submitted under this RFA.  Because the nature and
scope of the research proposed in response to this RFA may vary, the
size of an award will vary also.  However, it is anticipated that
between 12 and 20 new awards will be made under this RFA.  About 70
percent of funds will be directed toward projects testing novel
medications for relapse prevention, and about 30 percent toward
projects testing effects of novel medications on reduction of drug
use.

RESEARCH OBJECTIVES

Recent findings in clinical and preclinical neurosciences reveal
complex biological determinants underlying psychostimulant
dependence.  These include psychopathological, neuroanatomical,
pathophysiological, neuroadaptive, neurochemical, and hormonal
factors, and may involve a variety of nutritional, environmental and
toxicological substrates as underlying causes of drug addictions.
Psychostimulant dependence is associated with various degrees of
neuropathology and significant comorbidity with other neurological
and psychiatric disorders, including attention and mood disorders,
hypodopaminergia, hyposerotonergia, and hypofrontalism, manifested in
perfusion and metabolic/bioenergetic deficits, among others.  The
bioenergetic deficits induced by psychostimulants may promote brain
aging and facilitate neurodegenerative disorders in chronic
psychostimulant abusers.

Rational pharmacological interventions in these
biological/pathological substrates could be effective in treating
psychostimulant dependence.  Moreover, recent reemergence, reported
therapeutic success and safety of non-traditional pharmacotherapies,
including medically designed nutrition, supplements, vitamins, amino
acids, hormones and other natural compounds, in treating variety of
chronic disorders suggest exploration of non-traditional treatments
as potential therapies for cocaine/psychostimulant dependence.  Such
natural therapies, designed to normalize brain functions may be more
acceptable to treatment-seeking addicts, who often refuse to be
treated with conventional medications, and be more beneficial than
traditional pharmacotherapies, which often produce undesirable side
effects. It is expected that such therapies may be safe enough to be
used for treatment of addicted children, adolescents or pregnant
women.

The main objective of this RFA is to encourage clinical evaluation
of: (1) novel traditional medications with compounds and classes of
compounds previously not studied in clinical trials to treat
psychostimulant dependence, and; (2) non-traditional
pharmacotherapies, in relapse prevention designs in detoxified
cocaine/stimulant dependent participants, or reduction of drug use in
psychostimulant addicts.

The hypothesis and rationale for testing these novel medications
should address one or more of the following research/clinical
aspects:

1.  the persistent neurochemical imbalance and/or
neuroadaptive/neuropathological changes that have been described in
cocaine/psychostimulant dependent individuals or in animals treated
chronically with stimulants;

2.  the pharmacological intervention in neurochemical and
psychological factors contributing to vulnerability to stimulant
dependence (e.g., attention deficit hyperactivity disorder,
post-traumatic stress disorder);

3.  the hormonal abnormalities in cocaine/stimulant dependent
persons;

4.  the biochemical mechanism relevant for behavioral outcomes for
cocaine dependence (e.g., drug craving);

5.  neurochemical factors involved in expression of euphorigenic and
dependence-producing effects of psychostimulants;

6.  neurochemical factors responsible for persistent anhedonia,
depression, and anxiety, associated with psychostimulant withdrawal
and accompanying abstinence in chronic psychostimulant abusers;

7.  the availability of open clinical trial data or promising
preclinical results;

8.  other scientific or clinical rationales.

Investigators are encouraged to study novel medications, yet untested
for treatment of psychostimulant dependence (including those not
approved in the U.S., but approved in European and Asian
pharmacopeias) as well as a variety of nutritional factors,
supplements, and naturally occurring substances, rationally selected
to compensate for biochemical and functional deficits reported in
stimulant addicts (e.g., apparent deficiency of biogenic amines, an
imbalance in endogenous opioid peptides and other neurotransmitters)
and to restore the brain homeostasis in psychostimulant dependent
individuals.  We are soliciting applications that test the hypothesis
that correcting for persistent or permanent neuropathologies that are
associated with psychostimulant dependence with novel
pharmacotherapies may be effective in treating this disorder.

Possible examples of such treatments include: precursors of biogenic
amines and other neurotransmitters, vitamins and supplements that
modify neurotransmitter metabolism and energy metabolism, and herbs
of known therapeutic profile.  Examples of potential therapeutic
herbs may include: Ginkgo Biloba, Kudzu, Ginseng, Gotu Cola, and
Kelp, among others.  Encouraged also are pharmacological and natural
interventions in hormonal systems (e.g.,
hypothalamo-pituitary-adrenal axis, hypothalamo-pituitary-gonadal
axis, thyroid system, endogenous opioid peptides) that have been
shown to play a role in drug dependence. Medications designed to
improve deficient brain circulation, energy and phospholipid
metabolism, and cognition, will be also considered along with
rational combinations of treatments.

Because no pharmacotherapy is expected to be optimally effective
without concurrent behavioral therapy, adjunct therapies may
concentrate on psychological, behavioral processes such as motivation
building, relapse prevention skills, coping skills, skills for
utilization of alternative reinforcers, as well as meditation, or
imagery.

Drug dependence encompasses both physical and psychological
symptomatology; therefore, developing and testing integrative
approaches for treatment of psychostimulant dependence is encouraged
(i.e., treatments that stress pharmacotherapy, psychological support,
behavioral and nutritional adjustments, and social adaptations).  In
addition to testing potential treatments that affect primary
psychostimulant dependence, applications are encouraged to evaluate
novel treatments for disorders comorbid with drug dependence; these
include anxiety, depression, anhedonia, attention deficit and
cognitive impairments, antisocial behavior, post-traumatic stress
disorder, and other diagnoses that may contribute to continued
psychostimulant abuse and relapse.

The proposed studies should test the safety and efficacy of novel
therapeutic approaches in rigorously designed and executed clinical
trials to prevent relapse in persons detoxified from
cocaine/psychostimulant dependence or to reduce drug use in addicts.
Identified treatment modalities may be assessed in clinical
pharmacologic-therapeutic paradigms (laboratory clinical assessments)
and/or in phase I/II clinical trials that meet accepted standards for
Good Clinical Practice (GCP) guidelines established by FDA (21 CFR).
Because most psychostimulant abusers also co-abuse other substances
(alcohol, benzodiazepines, opiates), evaluation of the impact of
proposed new therapies on the use of the above drugs, in addition to
psychostimulants, will be also required.  Applications will be also
required to assess impact of the investigational agent on HIV risk
behaviors. Proposals must seek and obtain IRB review and approval
prior to submission or review of the application.

SPECIAL REQUIREMENTS

The exploratory, developmental (R21) and Small Grant (R03)
applications are limited to two years, are non-renewable, and are
limited in direct cost amount per year (R03, $50,000; R21, $90,000).
The R03 mechanism is intended for new, inexperienced investigators
and both are intended for established investigators exploring new
areas or departing from their usual research topics.  There are
special requirements for these mechanisms.  An applicant intending to
apply for them under this RFA should contact the named program person
in the INQUIRIES section for further information.

INCLUSION OF WOMEN AND MINORITIES IN RESEARCH INVOLVING HUMAN
SUBJECTS

It is the policy of the NIH that women and members of minority groups
and their subpopulations must be included in all NIH supported
biomedical and behavioral research projects involving human subjects,
unless a clear and compelling rationale and justification is provided
that inclusion is inappropriate with respect to the health of the
subjects or the purpose of the research. This new policy results from
the NIH Revitalization Act of 1993 (Section 492B of Public Law
103-43) and supersedes and strengthens the previous policies
(Concerning the inclusion of Women in Study Populations, and
Concerning the Inclusion of Minorities in Study Populations), which
have been in effect since 1990.  This new policy contains some new
provisions that are substantially different from the 1990 policies.

All investigators proposing research involving human subjects should
read the "NIH Guidelines for Inclusion of Women and Minorities as
Subjects in Clinical Research", which have been published in the
Federal Register of March 28, 1994 (FR 59 14508-14513) and reprinted
in the NIH Guide for Grants and Contracts of March 18, 1994, Volume
23, Number 11.

Investigators also may obtain copies of the policy from the program
staff listed under INQUIRIES.  Program staff may also provide
additional relevant information concerning the policy.

This RFA requires that proposed studies conduct gender comparisons of
clinical responses (side effects, efficacy, etc.) to the new
medications and strongly encourages examination of menstrual cycle
effects on the pharmacokinetics and pharmacodynamics of proposed new
therapies.
