The Collaboration Linking Opioid Use Disorder and Sleep ("CLOUDS") Study New Strategies to Prevent and Treat Opioid Addiction Sleep Dysfunction as a Core Feature of Opioid Use Disorder and Recovery NHLBI Yale University YAGGI, HENRY KLAR (contact); BARRY, DECLAN T; REDEKER, NANCY S; SCHEINOST, DUSTIN New Haven, CT 2019
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.

Pre-clinical evaluation of DT-001, a small molecule antagonist of MD2-TLR4 for utility in the treatment of pain Cross-Cutting Research Small Business Programs NINDS DOULEUR THERAPEUTICS, INC. YAKSH, TONY L; CHAKRAVARTHY, KRISHNAN San Diego, CA 2019

Summary:

 Chronic persistent post-operative pain (CPOP) is a devastating outcome from any type of surgical procedure. Its incidence is anywhere between 20-85% depending on the type of surgery, with thoracotomies showing one of the highest annual incidences of 30-60%. Given that millions of patients (approximately 23 million yearly based on incidence) are affected by CPOP, the results are increased direct medical costs, increased indirect medical costs due to decreased productivity, and associated negative effects on an individual’s physical functioning, psychological state, and quality of life. Given these extensive public health and economic consequences there is a resurgence of research in the area of preventative analgesia.  The goal of this project is to evaluate a novel small molecule antagonist of MD2-TLR4, DT-001 in preclinical models of surgical pain representative of persistent post-operative pain. In collaboration with University of California, San Diego, DT-001 will be evaluated for its ability to block the development of neuropathic pain states. These studies will evaluate dose escalating efficacy of DT001 in rats in formalin and spinal nerve injury (SNI) models using both intrathecal and intravenous routes of administration. Tissues will be preserved to assess functional effects on relevant pain centers for analysis by Raft. With demonstration of efficacy, these studies will determine the optimal dose and route of administration of DT001 and guide a development path to IND and eventually clinical trials.

Investigating the Contributions of Voltage Gated Sodium Channels to Oxaliplatin Induced Neuropathy Cross-Cutting Research Training the Next Generation of Researchers in HEAL NINDS UNIVERSITY OF CALIFORNIA AT DAVIS YAROV-YAROVOY, VLADIMIR M Davis, CA 2022
NOFO Title: Notice of Special Interest to Encourage Eligible NIH HEAL Initiative Awardees to Apply for PA-20-222: Research Supplements to Promote Diversity in Health-Related Research (Admin Supp - Clinical Trial Not Allowed)
NOFO Number: NOT-NS-20-107; PA-21-071
Summary:

Many molecular gates known as ion channels control the flow of electrical signals to sensory neurons and are thus key mechanisms and targets for understanding and interrupting pain signals. Recent breakthroughs in structural and computational biology shave illuminated specific molecular shapes of ion channels, which permits the improved design and refinement of small, stable protein-like molecules (peptide antigens). These peptides can stimulate an immune response that can then be targeted with a bioengineered antibody to match the peptide antigen. This project will test bioengineered antibodies in a rat model of chemotherapy-induced peripheral neuropathy within a region of the rat spinal cord that transmits signals to and from the brain.

NOFO Title: Optimization of Non-addictive Therapies [Small Molecules and Biologics] to Treat Pain (UG3/UH3 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-19-010
Summary:

Pain signals originate predominantly in a subset of peripheral sensory neurons that harbor a distinct subset of voltage-gated sodium (NaV) channels; however, current NaV channel blockers, such as local anesthetics, are non-selective and also block NaV channels vital for function of the heart, muscle, and central nervous system. Genetic studies have identified human NaV1.7, NaV1.8, and NaV1.9 channel subtypes as key players in pain signaling and as major contributors to action potential generation in peripheral neurons. ProTx-II is a highly potent and moderately selective peptide toxin that inhibits human NaV1.7 activation. This study will optimize ProTx-II selectivity, potency, and stability by exploiting the new structures of ProTx-II—human NaV1.7 channel complexes, advances in rational peptide optimization, and rigorous potency and efficacy screens to generate high-affinity, selective inhibitors of human NaV1.7, NaV1.8, and NaV1.9 channels that can define a new class of biologics to treat pain.

Development of Therapeutic Antibodies to Target Sodium Channels Involved in Pain Signaling Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS University of California, Davis YAROV-YAROVOY, VLADIMIR M (contact); TRIMMER, JAMES S Davis, CA 2022

NOFO Number: NS21-029
Summary:

Voltage-gated sodium channels such as Nav1.7, Nav1.8, and Nav1.9 transmit pain signals in nerve fibers and are molecular targets for pain therapy. While Nav channels have been validated as pharmacological targets for the treatment of pain, available therapies are limited due to incomplete efficacy and significant side effects. Taking advantage of recent advances in structural biology and computational-based protein design, this project aims to develop antibodies to attach to Nav channels and freeze them in an inactive state. These antibodies can then be further developed as novel treatments for chronic pain.
