NOFO Title: HEAL Initiative: Pharmacotherapies to Reverse Opioid Overdose Induced Respiratory Depression without Central Opioid Withdrawal (Target Validation and Candidate Therapeutic Development (R61/R33 - Clinical Trial Not Allowed)
NOFO Number: RFA-HL-20-031

NOFO Title: Development of Vaccines for the Treatment of Opioid Use Disorder
NOFO Number: BAA-DAIT-75N93019R00009
Summary:

High rates of relapse and overdose deaths pose significant challenges to the treatment of Opioid Use Disorder (OUD). Anti-opioid immunotherapies (i.e., vaccines and monoclonal antibodies) have great potential to reduce long-term opioid use and overdose, with minimal risk of side effects, when used in conjunction with pharmacological treatments and/or behavioral therapies. The ability of an anti-opioid vaccine to induce antibodies that render an opioid less effective, or less rewarding, and protect from accidental overdose could provide an important therapeutic option for patients undergoing treatment for OUD. The goal of this collaborative study is to design, develop, and evaluate vaccines for use in the treatment of opioid use disorder

NOFO Number: RFA-DA-19-002
Summary:

There is a need for longer-acting prophylactic pharmacologic options for opioid use disorder (OUD) patients during maintenance therapy. This study tests a titanium implant loaded with a formulation of naltrexone and a naturally occurring carboxylic acid. The device is implanted subcutaneously with local anesthetic during an in-office procedure. The technology is based on a unique formulation that keeps the pH within the reservoir low and promotes passive diffusion of naltrexone. The benefits of the product include complete medication adherence for one year after administration, fewer relapses, smooth profile ensuring complete prophylaxis without sub-therapeutic plasma troughs, full reversibility, and similar efficacy with less drug exposure. This technology has been validated clinically with another drug and tested preclinically with naltrexone. This project will finalize the chemistry manufacturing and controls, produce IND supplies, conduct an IND-enabling safety study, and submit the IND.

NOFO Title: Behavioral & Integrative Treatment Development Program (R01 Clinical Trial Optional)
NOFO Number: PA-18-055
Summary:

Often (around 40 percent of the time), individuals being treated for opioid use disorder (OUD) also have pain that interferes with daily life. This study builds on the prior development of a collaborative primary care approach, entitled TOPPS (Treating Opioid Patients’ Pain and Sadness), in which behavioral health specialists and primary care providers share a unified plan for addressing pain and depression in patients receiving buprenorphine. Building in preliminary work, researchers are conducting a randomized controlled trial of TOPPS compared to a health education contact-control condition among 250 persons with OUD recruited from two primary care-based buprenorphine programs, provided over 3 months and followed over 12 months. The study will examine whether this intervention changes how much pain interferes with daily functioning, the severity of pain, depression, and whether individuals stay in OUD treatment.

NOFO Number: RFA-DA-19-002
Summary:

Responding to urgent calls for non-opioid treatment, this research group has been evaluating the therapeutic potential of cannabidiol (CBD), a non-intoxicating cannabinoid, for the treatment of some clinical aspects of opioid use disorder (OUD). Preclinical animal studies show that CBD decreases cue-induced heroin-seeking behavior during drug abstinence, associated with incubation of craving. Clinical work has also shown that CBD was safe in combination with a potent opioid agonist to address a potential relapse condition and decreased craving and anxiety associated with heroin cues in abstinent individuals with heroin use disorder. Building on this foundation, the researchers will investigate an oral CBD powered by a novel patented technology (leveraging the kinetics of long-chain fatty acid absorption) in a gelcap delivery system that improves bioavailability, reduces the incidence of gastrointestinal side effects, reduces first pass metabolism, and enhances onset time. This study could lead to the development of a non-opioid, non-intoxicating FDA-approved medication to reduce opioid craving and relapse and restore global functioning in individuals with OUD.

NOFO Title: Development of Medications to Prevent and Treat Opioid Use Disorders and Overdose (UG3/UH3) (Clinical Trial Optional)
NOFO Number: RFA-DA-19-002
Summary:

In order to address the opioid crisis, this group has developed a candidate heroin/opioid vaccine that induces antibodies that bind heroin/opioid upon injection and subsequently prevent the drug from crossing the blood-brain barrier and interacting with the brain's µ-opioid receptor. They completed pre-clinical testing of the vaccine candidate in mice and rats and demonstrated that the animals were protected from subcutaneous and intravenous heroin challenge. Ongoing durability studies have demonstrated that antibody titer and protective efficacy were maintained 6 months after the last vaccination. This project proposes to advance the development of the vaccine candidate by conducting a Phase I/IIa human clinical trial, by performing vaccine synthesis, nonclinical studies, and then a clinical trial. The supplemental award will allow for testing the efficacy of fentanyl haptens and of the combination heroin–fentanyl vaccine.

NOFO Number: RFA-DA-19-002
Summary:

More than 100 million adults in the U.S. suffer from intermittent or constant chronic pain, and chronic pain affects at least 10 percent of the world’s population. The primary pharmaceuticals for treatment of chronic pain have been natural or synthetic opioids, and the use of opioids for pain treatment has resulted in what has been called an “epidemic” of opioid abuse, addiction, and lethal overdoses. Through a process of rational drug design, the research team has generated a new chemical entity (NCE) and have given it the name Kindolor, a non-opiate, non-addicting molecule that was shown to reduce or eliminate chronic pain in five animal models at doses compatible with use of Kindolor in humans. This project intends to complete the pre-clinical studies required for an IND application, which, if approved, would allow for proceeding onto the Phase 1 and 2 studies to assess safety and efficacy of the compound against osteoarthritic pain.

NOFO Title: Development of Medications to Prevent and Treat Opioid Use Disorders and Overdose (UG3/UH3) (Clinical Trial Optional)
NOFO Number: RFA-DA-19-002
Summary:

Extended-release naltrexone (XR-NTX) reduces overdose risk; however, transitioning to XR-NTX requires detoxification, which is a major hurdle. Non-opioid detoxification with an alpha-2 adrenergic receptor agonist, such as lofexidine, may shorten detoxification time, but it does not reduce the subjective effects of withdrawal. Pregabalin potentiates the activity of glutamic acid decarboxylase, inhibits calcium influx and release of excitatory neurotransmitters, raises GABA levels, and is approved for neuropathic pain, for fibromyalgia, and as an adjunctive therapy for adults with partial onset seizures. The study will test whether pregabalin can be combined with lofexidine to better reduce the subjective effects of opioid withdrawal than lofexidine alone and increase the proportion of patients that transition to XR-NTX. Such a dosing combination could lower the detoxification hurdle for patients who are interested in antagonist treatment or who are in settings where it is unavailable or difficult to access.

Summary:

The ongoing epidemic of opioid use disorder (OUD), overdose, and death is unprecedented. Available pharmacologic therapies for OUD have failed to stem the tide, plagued by poor adherence and retention, the principal factors associated with relapse and treatment failure. More than 80 percent of individuals with OUD are untreated. More treatment options are needed. This proposal seeks to develop a better antagonist-based OUD pharmacotherapy for populations highly motivated to achieve abstinence, such as military personnel, criminal justice clients, and the currently employed. A series of novel and proprietary small molecules will be designed and synthesized to address the adherence problem by inducing effective opioid antagonism with a single injection lasting at least 2 months, and up to 4 months or more. The goal of this project is to advance to Phase 3 clinical trials toward FDA approval of our lead compound. If successful, this project could lead to a novel therapeutic with superior adherence and retention, resulting in a significant public health impact by reducing rates of relapse, overdose, and death.
