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:

Opioid use disorder (OUD) is a chronic and relapsing brain disease that affects over 2 million Americans. Despite effective evidence-based treatments in the form of behavioral interventions and FDA-approved medication for addiction treatment (MAT), relapse rates are high. The Collaboration Linking Opioid Use Disorder and Sleep Study will investigate patients on MAT to elucidate potential causal mechanisms between sleep deficiency and OUD. The aims of this study are to 1) test whether there are different neurocognitive connectivity patterns between patients with adequate vs. deficient sleep in brain systems involved in addiction and assess the extent to which these “neural fingerprints” predict ongoing opioid use; 2) evaluate the potential biologic, psychiatric, and pharmacologic mechanisms that explain the causal pathway between sleep deficiency and opioid use; and 3) test ecologic factors such as psychosocial, family, and neighborhood contextual factors associated with OUD and their contribution to sleep deficiency among patients in MAT.

NOFO Title: NINDS Renewal Awards of SBIR Phase II Grants (Phase IIB) for Pre-Clinical Research (R44)
NOFO Number: PAR-17-480
Summary:

We discovered a class of non-opioid modulators of the T-type Cav3.2 channel that could treat neuropathic pain. In vivo pharmacokinetic and pharmacodynamic studies and preliminary toxicological studies identified AFA-279 and other candidates, which did not produce observable side-effects and showed greater analgesic effects than other neuropathic pain medications in rodent models. The goal of this proposed project is to submit the IND application on our Cav3.2 modulator to the Food and Drug Administration (FDA). We will produce AFA-279 under Good Manufacturing Practice (GMP)–like conditions using chemical manufacturing controls for Good Laboratory Practice (GLP) nonclinical toxicity studies and GMP clinical batch future Phase 1 clinical trials, complete toxicological and safety studies to establish the safety profile of AFA-279, prepare and submit the IND application, and then initiate early clinical trials. Our ultimate goal is to deliver a safer, more effective, non-opioid Cav3.2 channel modulator to patients suffering from neuropathic pain.

NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

The growing opioid use epidemic in the U.S. has been associated with a significant increase in the prevalence of pregnant opioid-dependent women and neonatal abstinence syndrome, which is associated with adverse health effects for the infant and with costly hospitalizations. Maintenance with sublingual (SL) buprenorphine (BUP) is efficacious for opioid use disorder but has disadvantages that may be heightened in pregnant women, including the potential for poor adherence, treatment dropout, and negative maternal/fetal effects associated with daily BUP peak-trough cycles. Extended release (XR) formulations may address some of these disadvantages. The primary objective of CTN-0080 is to evaluate the impact of treating opioid use disorder in pregnant women (n = 300) with BUP-XR, compared to BUP-SL, on maternal-infant outcomes. Other objectives include testing a conceptual model of the mechanisms by which BUP-XR may improve maternal-infant outcomes, relative to BUP-SL; determining the economic value of BUP-XR, compared with BUP-SL, to treat OUD in pregnant women; and evaluating the impact of BUP-XR, relative to BUP-SL, on neurodevelopment when the infant/child is approximately 12 and 24 months of age. Ultimately, this study will help in increasing access to treatment as well as provide quality care for pregnant/postpartum women.
