NOFO Title: HEAL Initiative: Interdisciplinary Teams to Elucidate the Mechanisms of Device-Based Pain Relief (RM1 Clinical Trial Optional)
NOFO Number: NS22-016
Summary:

Despite the need for non-opioid treatments for chronic pain, few alternative treatment approaches exist. Transcutaneous auricular neurostimulation (tAN) is a safe and effective treatment for pain during opioid withdrawal; however, researchers do not understand how tAN reduces pain, which limits its clinical use. A better understanding of how tAN affects neurophysiological processes to provide pain relief would likely expand tAN development and use. This interdisciplinary project will conduct research in both healthy adults and those with chronic pain to explain the neurochemical and neurophysiological mechanisms for tAN-based pain relief, and also help optimize treatments and their use.

NOFO Title: HEALing Communities Study: Developing and Testing an Integrated Approach to Address the Opioid Crisis (Data Coordinating Center) (UM1- Clinical Trials Not Allowed)
NOFO Number: RFA-DA-19-017
Summary:

Although there are effective prevention and treatment programs and services to address opioid misuse, opioid use disorder (OUD), and overdose, gaps remain between those needing and those receiving prevention and treatment, in part because of a need to better understand how to make these programs and services most effective at a local level. The National Institutes of Health (NIH) and the Substance Abuse and Mental Health Services Administration (SAMHSA) launched the HEALing Communities Study to generate evidence about how tools for preventing and treating opioid misuse and OUD are most effective at the local level. This multisite implementation research study will test the impact of an integrated set of evidence-based practices across health care, behavioral health, justice, and other community-based settings. The goal of the study is to reduce opioid-related overdose deaths by 40 percent over three years. As the Data Coordinating Center, RTI will provide coordination and facilitate communications to unite the HEALing Communities Study research centers into a cohesive research cooperative.

NOFO Title: HEAL Initiative: Harm Reduction Policies, Practices, and Modes of Delivery for Persons with Substance Use Disorders (R01 Clinical Trial Optional)
NOFO Number: RFA-DA-22-046
Summary:

People who use drugs often have other medical problems that cause them to visit an emergency department frequently. This project will develop and test an intervention aimed at reducing health risk among Black people who use drugs that visit an urban emergency department for care. The intervention will be delivered by people with lived experience of drug use and tailored to meet the unique needs of Black people who use drugs.

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.

NOFO Title: HEAL Initiative: Integrative Management of Chronic Pain and OUD for Whole Recovery (IMPOWR): Research Centers (RM1 Clinical Trial Required)
NOFO Number: RFA-DA-21-030
Summary:

There are a dearth of integrated treatments that simultaneously address the fundamental causes of chronic pain and opioid misuse/opioid use disorder and that focus on well-being among individuals with chronic pain and opioid misuse/disorder. This research will study how to improve the lives of patients with chronic pain and opioid misuse/disorder via tailored interventions that explicitly target increasing quality of life and engagement in valued activities, the cultural centering of interventions to meet the needs of diverse patient populations and reducing stigma of chronic pain and opioid misuse/disorder. Specific research projects will i) test the effectiveness, mechanisms, and implementation of an integrated psychosocial treatment for chronic pain and opioid use disorder among individuals receiving buprenorphine from outpatient treatment clinics, and ii) will use community-based participatory research methods to develop a culturally centered strategy for screening and brief intervention of chronic pain and opioid use disorder among American Indian/Alaska Native patients in primary care settings. This research will shed light on a difficult problem and improve health and wellbeing with a focus on diverse and underserved populations.

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:

Few integrated treatments are available that simultaneously address the fundamental causes of chronic pain and opioid misuse/opioid use disorder and focus on well-being among individuals with chronic pain and opioid misuse/opioid use disorder. This research will inform development of patient-centered interventions that increase quality of life and engagement in valued activities, are culturally appropriate for use by diverse patient populations, and reduce stigma related to chronic pain and opioid misuse/opioid use disorder. The results of this project will be used to inform future research focused on developing mobile health treatments for individuals with chronic pain and opioid use disorder, and for developing culturally appropriate treatments for chronic pain and opioid use disorder in Hispanic/Latino individuals.

NOFO Title: HEAL Initiative: Secondary Analysis and Integration of Existing Data Related to Acute and Chronic Pain Development or Managementin Humans (R21 Clinical Trials Not Allowed)
NOFO Number: RFA-DE-22-011
Summary:

Chronic pain is a persistent source of disability and reduced quality of life for aging adults. Chronic pain-related outcomes are disproportionately worse for aging African Americans, who report greater pain severity and worse pain-related disability compared to White peers. A significant pain risk factor for African Americans is chronic stress (including family-related stress), which is worsened by structural inequities that affect this population. Although many African Americans identify family support as critical for pain self-management, this influence has not been studied thoroughly. This project will study how pain conditions develop and persist for aging African Americans by analyzing existing data from African American participants in two large aging studies: Midlife in the U.S. (721 participants) and the Health and Retirement Study (2,698 participants). The research aims to determine how family emotional climate affects pain risk, taking into account structural factors like discrimination, socioeconomic disparity, and the influence of various neighborhood settings.

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: 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: 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.

NOFO Title: HEAL Initiative: Planning Studies for Initial Analgesic Development [Small Molecules and Biologics] (R61 Clinical Trial Not Allowed)
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.
