Long-acting ghrelin for neuropathy Cross-Cutting Research Small Business Programs NINDS EXTEND BIOSCIENCES, INC. SOLIMAN, TARIK Newton, MA 2019
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:

There is a need for safe, effective, well- tolerated drugs to treat painful neuropathy by halting or reversing the underlying pathology of the disease. One promising approach to treating painful neuropathy without opioids is the use of ghrelin, a 28-amino acid acylated peptide hormone. However, it has a short half-life and must be delivered via a constant intravenous infusion to have a therapeutic effect. Extend Biosciences' D-VITylation platform technology is truly enabling for small peptide-based therapeutics that are rapidly cleared from the bloodstream by renal filtration. The platform harnesses the naturally long half-life of vitamin D and its dedicated binding protein, VDBP. When the vitamin D molecule is conjugated to a biological therapeutic, it dramatically improves the half-life and bioavailability of the drug. Use of the technology should also allow the drug to be self-administered by subcutaneous injection. This would be of significant benefit to patients. In this project, the team will test the efficacy of EXT405 in a cell-based model of neuropathy as well as in animal models of CIPN and diabetes- induced neuropathy.

Long-acting buprenorphine vs. naltrexone opioid treatments in CJS-involved adults Translation of Research to Practice for the Treatment of Opioid Addiction Justice Community Opioid Innovation Network (JCOIN) NIDA NEW YORK UNIVERSITY SCHOOL OF MEDICINE LEE, JOSHUA D; FARABEE, DAVID J; MARSCH, LISA A; SCHWARTZ, ROBERT P; SPRINGER, SANDRA ANN; WADDELL, ELIZABETH NEEDHAM New York, NY 2019
NOFO Title: HEAL Initiative: Justice Community Opioid Innovation Network (JCOIN) Clinical Research Centers (UG1 Clinical Trial Optional)
NOFO Number: RFA-DA-19-025
Summary:

This study will assess the implementation of an evidence-based treatment in correctional settings by comparing the effectiveness of two medications used to treat opioid use disorder—extended-release buprenorphine (XR-B) vs. extended-release naltrexone (XR-NTX)—among adults currently incarcerated in U.S. jails and prisons at five distinct trial sites. This study will allow providers, correctional and public health authorities, payers, and policymakers’ timely and relevant data to assess the effectiveness of these medications as potentially useful re-entry treatment options. Findings from this study have implications for expanding public safety and limiting the societal costs of heroin, fentanyl, and prescription opioid addictions.

Long-Acting Biodegradable Buprenorphine Depots Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA PURDUE UNIVERSITY OTTE, ANDREW West Lafayette, IN 2023
NOFO Title: Development of Medications to Prevent and Treat Opioid and/or Stimulant Use Disorders and Overdose (UG3/UH3 - Clinical Trial Optional)
NOFO Number: PAR-22-200
Summary:

Buprenorphine is an effective treatment for opioid use disorder, but its use is limited due to the need for frequent dosing. This project will optimize the molecular features of an injectable, biodegradable, long-acting (3-month) buprenorphine implant that would not require surgical removal. The research aims to advance toward testing in human research participants.

LIGHT and Lymphotoxin targeting for the treatment of chronic orofacial pain conditions Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDCR UNIVERSITY OF TEXAS HLTH SCIENCE CENTER AKOPIAN, ARMEN N San Antonio, TX 2019
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

Mismanagement of orofacial chronic pain, such as temporomandibular joint and muscle disorders (TMJD) and oral cancer, substantially contributes to opioid overuse; overdose-related deaths; and cardiovascular, renal, and neurological complications at epidemic proportions. The current paradigm implies that orofacial conditions could trigger maladaptation of the immune system and plasticity supporting persistent inflammation, which influences the development and maintenance of orofacial chronic pain. LIGHT (TNFSF14) and Lymphotoxin-beta (LT?), members of the tumor necrosis factor superfamily, provide a balance between protective immunity and immunopathology during chronic inflammatory diseases. This project will test the hypothesis that targeting LIGHT and LT? signaling could prevent the development and inhibit the maintenance of chronic pain produced by TMJD and oral cancer, via peripheral mechanisms involving plasticity of immune, stromal, and tumor cells, as well as sensory neurons. The proposed research is significant as it advances our understanding of mechanisms regulating the development and maintenance of orofacial pain and offers new therapeutic targets and an immunotherapeutic approach for preventing and blocking chronic pain during TMJD and oral cancer.

NOFO Title: Notice of Special Interest to Encourage Eligible NIH HEAL Initiative Awardees to Apply for PA-18-906 Research Supplements to Promote Diversity in Health-Related Research (Admin Supp - Clinical Trial Not Allowed)
NOFO Number: NOT-NS-20-023
Summary:

Chronic orofacial pain during Temporomandibular Disorders (TMD) and oral cancer is a significant health problem with scarce non-opioid treatment options. This study aims to validate critical regulators of the balance between protective immunity and immunopathology during chronic inflammatory diseases?tumor necrosis factor alpha superfamily members, LIGHT (TNFSF14) and lymphotoxin-beta (LT?) and their receptors, LT?R and Herpes Virus Entry Mediator (HVEM)?as novel therapeutic targets. The study also seeks to determine whether inhibition of LIGHT and LT? signaling prevents the development and inhibits maintenance of chronic TMD and oral cancer pain via peripheral mechanisms involving plasticity of immune, muscle and tumor cells as well as sensory neurons. The study will define the contribution of LIGHT and LT? signaling to TMD-induced excitability of trigeminal sensory neurons innervating the masseter muscle and joint. New validated therapeutic targets for prevention and treatment of orofacial pain that can be peripherally targeted would reduce side effects of current pain medicates related to drug dependence or tolerance.
