NOFO Title: HEAL Initiative: Sleep and Circadian-Dependent Mechanisms Contributing to Opiate Use Disorder (OUD) and Response to Medication Assisted Treatment (MAT) (R01 - Clinical Trial Not Allowed)
NOFO Number: RFA-HL-19-028
Summary:

Profound sleep disturbances during abstinence have long been suspected of perpetuating vulnerability to relapse of people who misuse or are addicted to opioids. An animal model has shown that long-term sleep deficiency results in a persistent state of physiological dysregulation that is expected to modify the biology of abstinence and increase relapse potential. This study seeks to discover how persistent sleep restriction during withdrawal from opioid use increases vulnerability to relapse in the animal model by testing whether persistent sleep restriction during abstinence from opioid use is sufficient to increase opioid drug seeking. The functional outcome measure will be the degree of mitigation of opioid seeking. These studies will provide a basis for novel translational approaches to target mechanisms that are demonstrated to cause increased vulnerability to relapse.

Summary:

This study will examine the epidemiology of injection drug use, its infectious consequences, and service accessibility among young persons who inject drugs (PWID) in 15 rural counties in Maine, New Hampshire, and Vermont, then implement an integrated telemedicine approach to treat opioid use disorder (OUD) and reduce infections and overdose. The UG3 phase will characterize the risk environment and epidemiology of OUD, its infectious complications, opioid overdose, risk behaviors, service use, and needs in young PWID in these counties. An environmental assessment of policy and infrastructure will examine available services, needs, and gaps. The UH3 phase will evaluate the effectiveness of a regionalized integrated model of expanded service delivery for rural PWID. This project will provide in-depth understanding of high-risk rural PWID, inform community response strategies, and implement a comprehensive, integrated approach to treat OUD and reduce overdose and infectious complications among PWID in the rural United States.

NOFO Title: HEAL Initiative: Sleep and Circadian-Dependent Mechanisms Contributing to Opiate Use Disorder (OUD) and Response to Medication Assisted Treatment (MAT) (U01 Clinical Trial Optional)
NOFO Number: RFA-HL-19-029
Summary:

FDA-approved medications for treating opioid use disorder are effective, but there is a significant unmet need for alternatives, especially relapse prevention. NIDA and the FDA have encouraged investigators to expand the range of therapeutic outcomes, beyond measurement of abstinence. Insomnia is a clinically significant, but understudied, correlate/predictor of relapse to substance use. Yet most medications for treating insomnia have limited efficacy and can produce side effects. The orexin (OX) system plays a key role in sleep and substance use, offering a promising avenue for study. This project will address whether OX-1/2 antagonism is a mechanism that can directly improve outpatient opioid abstinence, or whether OX antagonism corrects sleep deficiencies and indirectly improves opioid abstinence. Specific aims are to determine whether nightly treatment with the OX-1/2 antagonist suvorexant, relative to placebo, 1) increases outpatient opioid abstinence and 2) improves sleep efficiency on the residential detoxification unit. The study will also determine 3) whether improved sleep efficiency predicts greater opioid abstinence (regardless of group assignment).

NOFO Title: PHS 2018-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44] Clinical Trial Not Allowed)
NOFO Number: PA-18-574
Summary:

Current drug-screening immunoassays use benchtop analyzers that require experienced personnel, time, and a laboratory setup. Physicians without access to in-house testing have to send out patient samples for screening, resulting in unacceptable delays in the treatment of patients who are potentially suffering from chronic pain. This project, a partnership with BreviTest Technologies, LLC, aims to develop a low-cost, point-of-care (POC) urine drug testing (UDT) device to detect opioids. The goal is for a portable platform to deliver quantitative performance similar to a standard laboratory test for opioids within a 10-minute run time. If successful, this will provide a technology capable of performing rapid quantifications of urine drug levels in a physician’s office, providing an invaluable tool to render more effective pain management dosing to patients, thus paving the way toward lower toxicity and a better quality of life.

Summary:

The Family School Partnership (FSP) and classroom-centered (CC) interventions targeted aggressive-coercive behavior and poor academic achievement as antecedents of the distal outcomes of antisocial behavior, substance abuse/dependence, psychiatric symptoms/disorders, high-risk sexual behavior and successful adaptation to the relevant developmental demands of the educational, work, romantic relationships and family (both family of procreation and origin/orientation) social fields/contexts. The participants of the FSP and CC original prevention trial were a population (n = 798) of urban, predominately African-American young adults, who began first grade in the fall of 1993 in nine elementary schools in predominantly low- to lower-middle-income Baltimore areas. The central purpose of the proposed study is to extend through ages 31-35 an examination of normal and pathogenic development and the impact of these two universal first-grade preventive interventions on the distal targets mentioned above. We will continue to study the role of phenotypic and genetic factors (and their interactions) as well as the impact of the interventions on the development and course of substance use/abuse/dependence, psychiatric symptoms/disorders, antisocial behavior/disorder and high-risk sexual behavior through young adulthood. The knowledge accrued over the course of the proposed assessments should serve to inform the nature, targets and timing of our future preventive intervention efforts.

NOFO Title: HEAL Initiative: Translational Development of Devices to Treat Pain (U18 Clinical Trial Not Allowed)
NOFO Number: RFA-EB-18-003
Summary:

For patients with neuropathic pain refractory to therapy using small molecules, modulation of specific neural structures in the central or peripheral nervous system can provide effective alternative treatments. While current Food and Drug Administration–approved devices for dorsal root ganglion (DRG) stimulation are safe and effective, there have been an unfortunate number of adverse events associated with pulse generator infections and lead migration. The research team will develop a wireless, millimeter-sized nerve stimulator that can be delivered through the vasculature and stimulate the DRG to alleviate symptoms of neuropathic pain and the associated minimally invasive delivery method. This endovascular nerve stimulation (EVNS) system depends on development and integration of key novel technologies into an endovascular stent. The magnetoelectric transducers and electronic circuits will convert wireless power and data into stimulus patterns that can trigger neural activity in the DRG via miniature electrodes. After chronic demonstration of safety and functionality in large animal models, the team will prepare for regulatory discussions with the FDA. If successful, the EVNS will provide a technology platform for treating other neuropathic pain syndromes. 

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:

Methadone is useful in the treatment of opioid dependence; however, methadone misuse and methadone-related fatalities have increased. Ensysce has created two complementary, novel technologies that can be applied to methadone. Their Trypsin Activated Abuse Protection (TAAP™) prodrugs are “enzyme-activated” to release clinically effective opioid drugs only when taken orally and exposed to the correct physiologic conditions, such as exposure to trypsin in the small bowel. Their multi-pill abuse resistance (MPAR™) feature involves in situ bioregulation of opioid delivery from the TAAP™ systems, enabling control over oral multi-dose pharmacokinetic profiles. It is envisaged that an R-methadone-TAAP™ prodrug would demonstrate similar reduced addiction liability as with other opioid-TAAP products. The objective of this proposal is to develop an R-methadone-TAAP™/MPAR™ drug through Phase 1 clinical studies and to translate R-methadone-TAAP™/MPAR™ results into humans, to ultimately reduce the misuse and oral overdose potential of methadone.

NOFO Title: NIH Exploratory/Developmental Research Grant Program (Parent R21 Clinical Trial Required)
NOFO Number: PA-18-344
Summary:

Chronic pain is a significant public health problem associated with tremendous personal and economic burden. First-line treatment consists of opioid medications, but despite only moderate efficacy and unpleasant side effects, rates of opioid prescriptions have quadrupled over the past 15 years, and this has contributed to high rates of misuse, overdose, and mortality. Clearly, alternative, or non-opioid strategies for treating pain are needed. In this context, “opioid-sparing” medications refer to compounds that can be combined with and enhance the analgesic effects of lower-dose opioids without increasing the rewarding properties of either drug. There is preclinical evidence suggesting that cannabidiol (CBD) may have the potential to function as “opioid-sparing” medications, but its ability to alter opioid-mediated analgesia in humans has yet to be determined. This proposal will fill this gap by conducting a double-blind, placebo-controlled, within-subject randomized crossover study of the effects of CBD and morphine co-administration on pain sensitivity and subjective reinforcement on 28 healthy males and females. This is the first known study to investigate the ability of CBD to alter morphine’s analgesic effects in humans. If successful, the model will have a lasting impact on our ability to develop and test medications that reduce our reliance on chronic use of opioid medications for pain relief.

NOFO Number: PA-18-591
Summary:

For many reasons, the emergency department (ED) is a critical venue to initiate opioid use disorder (OUD) interventions. ED patients have a disproportionately high prevalence of substance use disorders and are at an elevated risk of overdose, and many do not access health care elsewhere. Despite this, OUD interventions are rarely initiated in EDs. The Emergency Department Connection to Care with Buprenorphine for Opioid Use Disorder study (CTN-0079) will assess the feasibility, acceptability and impact of introducing clinical protocols for screening for OUD, buprenorphine treatment initiation, and referral for ongoing treatment in ED settings with high need, limited resources and different staffing structures. This extension study will use the existing infrastructure to evaluate the adoption and sustainability of the clinical protocols introduced at each of the study sites and to identify factors influencing their diffusion and effectiveness.

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

The United States has seen dramatic increases in fatal overdoses due to heroin, counterfeit prescription drugs, and cocaine adulterated with fentanyl or fentanyl-like analogs. Current medications may not be sufficient to address the opioid overdose epidemic. As a complementary strategy, the researchers plan to develop vaccines against fentanyl and fentanyl-like compounds to reduce their abuse liability and the growing incidence of fatal overdoses. This research team has already developed vaccines against heroin and oxycodone that stimulate the production of antibodies effective in reducing opioid distribution to the brain, opioid-induced behaviors, and opioid-induced respiratory depression and have identified a promising fentanyl vaccine candidate cued up for optimization. Successful completion of an anti-fentanyl vaccine development project could offer a long-lasting, safe, and cost-effective intervention complementary to medication-assisted treatment (MAT) and may reduce overdoses in opioid users as well as protect people in professions (e.g., law enforcement, airport security, postal workers) at risk of accidental exposure to fentanyl and fentanyl analogs.
