INTEGRATED MICROPHYSIOLOGICAL SYSTEM OF CEREBRAL ORGANOID AND BLOOD VESSEL FOR DISEASE MODELING AND NEUROPSYCHIATRIC DRUG SCREENING Preclinical and Translational Research in Pain Management NCATS COLUMBIA UNIVERSITY HEALTH SCIENCES LEONG, KAM W NEW YORK, NY 2018
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

The clinical utility of opioids for pain treatment is limited by its risk for developing opioid usage disorders (OUD). These untoward effects impose a severe burden on society and present difficult therapeutic challenges for clinicians. We propose to extend our cerebral organoid MPS to facilitate the investigation of neuronal response to opioids and identify cellular and molecular signatures in patients vulnerable to OUD. We have assembled a team with complementary expertise in clinical characterization of OUD, cerebral organoid MPS modeling, single cell RNA-seq technology, and functional characterization of neurons in a mesolimbic reward system to test the hypothesis that midbrain MPS is a clinically relevant pre-clinical model for study of opioid usage disorder.

Targeting Endosomal Receptors for Treatment of Chronic Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS COLUMBIA UNIVERSITY HEALTH SCIENCES BUNNETT, NIGEL W; SCHMIDT, BRIAN L New York, NY 2020
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:

Many non-opioid drugs target G Protein-Coupled Receptors (GPCRs), a family of proteins involved in many pathophysiological processes including pain, fail during clinical trials for unknown reasons. A recent study found GPCRs not only function at the surface of nerve cells but also within a cell compartment called the endosome, where their sustained activity drives pain. This study will build upon this finding and test whether the clinical failure of drugs targeting plasma membrane GPCRs is related to their inability to target and engage endomsomal GPCRs (eGPCRs). This study will use stimulus-responsive nanoparticles (NP) to encapsulate non-opioid drugs and selectively target eGPCR dyads to investigate how eGCPRs generate and regulate sustained pain signals in neuronal subcellular compartments. This study will also validate eGCPRs as therapeutic targets for treatment of chronic inflammatory, neuropathic and cancer pain. Using NPs to deliver non-opioid drugs, individually or in combinations, directly into specific compartments in nerve cells could be a potential strategy for new pain therapies.

Prevention of renarcotization from synthetic opioids Cross-Cutting Research Small Business Programs NIDA CONSEGNA PHARMA, INC. AVERICK, SAADYAH Pittsburgh, PA 2019
NOFO Title: HEAL Initiative: America’s Startups and Small Businesses Build Technologies to Stop the Opioid Crisis (R43/R44 - Clinical Trial Optional)
NOFO Number: RFA-DA-19-019
Summary:

While the mu opioid receptor (MOR) antagonist naloxone has proven invaluable as an opioid overdose antidote, naloxone suffers from a very short duration of action (half-life is approximately 1 hour) and has been found to be less effective against newer, long-acting opioids, including fentanyl (half-life is approximately 7–10 hours). This leads to a highly lethal and increasingly prevalent phenomenon known as “renarcotization,” wherein an overdose patient revived with naloxone can re-enter an overdose state from residual fentanyl in the body. Thus, there is a critical need to develop a long-acting MOR antagonist formulation that can address renarcotization by providing multi-hour protection. The goal of this project is to reformulate naloxone using FDA-approved microencapsulation technology into a long-acting injectable (LAI) that can provide 12–24 hours of sustained antagonist activity in vivo. It will employ a proprietary Computational Drug Delivery™ software, called ADSR™, to perform in silico formulation optimization as well as to predict its in vitro dissolution and in vivo pharmacokinetic behavior.

RAE (REALIZE, ANALYZE, ENGAGE)- A DIGITAL BIOMARKER BASED DETECTION AND INTERVENTION SYSTEM FOR STRESS AND CRAVING DURING RECOVERY FROM SUBSTANCE ABUSE DISORDERS Cross-Cutting Research Small Business Programs NIDA ContinueYou, LLC Reinhardt, Megan Rois Bristol, ME 2019
NOFO Title: Wearable to Track Recovery and Relapse Factors for People w/ Addiction (R43/R44)
NOFO Number: RFA-DA-18-010
Summary:

For many individuals in recovery from a substance use disorder, certain cues—including stress and drug-related cues—can trigger a physiological state in which they are more likely to relapse. In this SBIR project, the investigators intend to deploy a system—consisting of a wearable sensor, a smartphone app, and a clinical portal—to provide individuals in recovery and their treatment providers with an opportunity to identify moments of high risk for relapse and to access real-time intervention opportunities. The sensors will identify signals of stress or drug use, interface with a smartphone app, and provide options for annotations, stress-reduction techniques, or contact with an individual’s support system and treatment providers, as well as log and encourage healthy behaviors. This study will deploy and optimize the system, as well as test its effects on addiction-related outcomes, such as rate of relapse.

Transcutaneous Phrenic Nerve Stimulation for Treating Opioid Overdose Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA CORIDEA, LLC LEVIN, HOWARD (contact); COMER, SANDRA D; GUEDES, ALONSO; WAGENER, GEBHARD New York, NY 2023
NOFO Title: Device-Based Treatments for Substance Use Disorders (UG3/UH3, Clinical Trial Optional)
NOFO Number: PAR-20-279
Summary:

Difficulty breathing is a hallmark symptom of an opioid-related overdose and can result in permanent brain injury or death within minutes. This project will develop a community-deployable Automated External Respiration System device that can restore and sustain breathing in people experiencing opioid-induced respiratory depression. The device stimulates the phrenic nerve in the chest that controls breathing until other medical interventions are available or the patient recovers. The research will develop and validate the automated external respiration system for testing in human research participants and ultimately aims to develop a system usable in a community setting.

Development of a Novel Chemokine Receptor Antagonist as a Treatment for Opioid Use Disorder Cross-Cutting Research Small Business Programs NIDA CREATIVE BIO-PEPTIDES, INC. RUFF, MICHAEL R Potomac, MD 2021
NOFO Title: HEAL Initiative: Development of Therapies and Technologies Directed at Enhanced Pain Management (R43/R44 – Clinical Trial Not Allowed)
NOFO Number: RFA-NS-20-011
Summary:

Chemokines (hormones of the immune system that mediate innate immune inflammation) enhance pain, reduce opioid analgesia, and promote drug-seeking behavior and addiction, giving them a central role at the crossroads of chronic pain and the opioid crisis. Blocking chemokines (rather than opioid receptors) provides an exciting treatment opportunity for both pain and opioid use disorder. This research continues previous work studying the efficacy of RAP-103, a small, orally stable chemokine receptor blocker. The previous research has shown that RAP-103 is safety and effective in preclinical models that mimic human drug-taking. This research will now optimize the dose required to achieve decreased motivation to maintain opioid use, establish manufacturing scale-up feasibility, provide RAP-103 for safety testing in animals, and conduct stability testing of RAP-103 toward the goal of submitting an Investigational New Drug application to the FDA.

A Novel Chemokine Receptor Antagonist to Block Opioid Reinforcement, Relapse and Physical Dependence Cross-Cutting Research Small Business Programs NIDA CREATIVE BIO-PEPTIDES, INC. RUFF, MICHAEL Potomac, MD 2019
NOFO Title: HEAL Initiative: America’s Startups and Small Businesses Build Technologies to Stop the Opioid Crisis (R43/R44 - Clinical Trial Optional)
NOFO Number: RFA-DA-19-019
Summary:

Current agonist treatments for opioid use disorder (OUD) are not adequate to address the opioid crisis and have abuse liability concerns. Chemokines (hormones of the immune system that mediate innate immune inflammation) enhance pain, reduce opioid analgesia, and promote drug-seeking behavior and addiction—giving them a central role at the crossroads of chronic pain and the opioid crisis. So blocking chemokines (rather than opioid receptors) provides an exciting and untested treatment opportunity for pain and OUD. This proposal will assess, in animal self-administration models that mimic human drug-taking, whether a chemokine antagonist peptide R103 reduces morphine intake, as well as if R103 will prevent or blunt naloxone-precipitated withdrawal signs in morphine-dependent rats and stop relapse.

Structure-Function and Signaling of Glutamate Delta 1 in Pain Mechanism Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS CREIGHTON UNIVERSITY DRAVID, SHASHANK MANOHAR Omaha, NE 2023
NOFO Title: Emergency Awards: HEAL Initiative-Early-Stage Discovery of New Pain and Opioid Use Disorder Targets Within the Understudied Druggable Proteome (R21 Clinical Trial Not Allowed)
NOFO Number: RFA-TR-22-011
Summary:

There is an urgent need to find new ways to treat chronic pain through better targeting of underlying biological processes. Research shows that flexible synapses within the amygdala brain region play a role in the progression of pain from acute to chronic, but the details are not fully understood. The receptor glutamate delta 1 helps to form and maintain synapses in the amygdala in inflammatory and neuropathic pain. This project will study how the shape and characteristics of glutamate delta 1 affect pain conditions that involve the amygdala, toward informing future development of pain medications.

Psychosocial Risk Factors for Chronic Pain: Characterizing Brain and Genetic Pathways and Variation Across Understudied Populations Cross-Cutting Research Leveraging Existing and Real-Time Opioid and Pain Management Data NCCIH DARTMOUTH COLLEGE WAGER, TOR D Hanover, NH 2022
NOFO Title: HEAL Initiative: Secondary Analysis and Integration of Existing Data Related to Acute and Chronic Pain Development or Management in Humans (R21 Clinical Trials Not Allowed)
NOFO Number: RFA-DE-22-011
Summary:

Fifty million Americans experience chronic pain, including about 25 million who report pain that substantially interferes with daily activities and reduces quality of life. Mental health problems, including depression, anxiety, and post-traumatic stress disorder, increase risk for severe chronic pain. This project will use genetic data, information about observable characteristics (phenotypic data), and neuroimaging data from three large databases to identify psychosocial factors that predict chronic pain, assess differences across diverse U.S. populations, and determine whether risk profiles predict post-surgical chronic pain.

NOFO Number: RFA-AT-18-002
Summary:

New Hampshire can anticipate as many as 1,000 infants born with prenatal opioid exposure each year. Pain management is complicated for pregnant women with opioid use disorder (OUD), and undermanagement of pain is a strong risk factor for relapse. Contemplative interventions, such as yoga and mindfulness, may reduce risks for relapse for pregnant and parenting women with OUD. This project represents a partnership with New Hampshire stakeholders to develop and pilot evaluation of a trauma-informed yoga and mindfulness relapse prevention intervention (Mindful Moms in Recovery: MMORE). It aims to: 1) identify needs and areas of adaptation of trauma-informed yoga and mindfulness-based relapse prevention protocols through formative work with pregnant and parenting woman; 2) develop an integrated 10-session intervention protocol with iterative feedback from client stakeholders; and 3) evaluate feasibility, acceptability, and efficacy trends of MMORE in a pre-post pilot with pregnant women.

Expanding Clinical Research Training on Implementing the Evidence-based Hub and Spoke Model of Medication for Opioid Use Disorder (MOUD) Translation of Research to Practice for the Treatment of Opioid Addiction Enhancing the National Drug Abuse Treatment Clinical Trials Network to Address Opioids NIDA DARTMOUTH COLLEGE MARSCH, LISA A. Hanover, NH 2019
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

As part of an ongoing teleECHO learning collaborative (LC),this study will expand clinical research training in evidence-based quality improvementmethods that were central to delivering and sustaining science-based medication-assisted treatment for opioid use disorder (MOUD) within the Vermont Hub-and-Spoke Model (HSM) with fidelity. Participating primary care practices will be trained in the (1) use of astudy-developedtoolkit of research and evaluationquality improvementmethodsintended to expand provider knowledge and performance in the delivery of evidence-based MOUD, (2) systematic tracking of standardized outcome metrics, and (3) sharing of these standardized data with other LC membersso that practices can use this empirical information to refine their care model over time. The study will measure changes in providers’ knowledge about best practices for MOUD, their comfort in caring for OUD patients with MOUD and their performance on all the standardized outcome metrics.

Ancillary Study of the Adoption and Sustainability of ED-Initiated Buprenorphine Translation of Research to Practice for the Treatment of Opioid Addiction Enhancing the National Drug Abuse Treatment Clinical Trials Network to Address Opioids NIDA DARTMOUTH COLLEGE MARSCH, LISA A. Hanover, NH 2019
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
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.

OUD Phenotyping Feasibility for Clinical Trials Translation of Research to Practice for the Treatment of Opioid Addiction Enhancing the National Drug Abuse Treatment Clinical Trials Network to Address Opioids NIDA DARTMOUTH COLLEGE MARSCH, LISA A. Hanover, NH 2019
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

Very little research has been conducted on better understanding of phenotypic characterization of individuals with OUD (beyond DSM-5 diagnoses) and how these features predict illness severity, treatment retention or outcomes. The primary objective of the deep phenotyping study is to provide a comprehensive phenotypic characterization (e.g., domains of negative affect, reward salience, cognitive control, mental health) of a heterogeneous sample of individuals (n = 1,000) who currently meet one or more DSM-5 diagnostic criteria for OUD and are in treatment for OUD. In a subset of this sample (n = 100), the investigators conduct digital phenotyping to examine the utility of ecological momentary assessment (EMA), digital sensing and social media to predict retention, medication adherence and opioid use outcomes in patients receiving buprenorphine for OUD. It is anticipated that this foundational study will inform the feasibility and utility of such assessments that can be successfully embedded into imminent and future CTN and other OUD clinical trials.

Rural Expansion of Medication Treatment for Opioid Use Disorder Translation of Research to Practice for the Treatment of Opioid Addiction Enhancing the National Drug Abuse Treatment Clinical Trials Network to Address Opioids NIDA DARTMOUTH COLLEGE MARSCH, LISA A. Hanover, NH 2019
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

People who use opioids in rural areas suffer worse health and less insurance coverage. The opioid problem in rural areas is of particular concern, as rural areas have higher overdose rates despite equivalent rates of OUD. This is because rural areas have a scant number of clinics and clinicians who provide medication treatment for OUD. Thus, people living in rural areas must travel long distances to access clinics that may or may not have expertise in providing treatment to patients with OUD. Telemedicine (TM) could efficiently increase capacity for delivery of buprenorphine in rural areas and may increase the number of patients receiving medication treatment and improve treatment retention and outcomes. While the development of medication treatments for opioid use disorder (MOUD) capacity in primary care settings with optimal/comprehensive services is desirable, the current opioid crisis with escalating overdose death rates in rural areas suggests a need to implement an efficient, cost-effective system of MOUD services that can be scaled up quickly. The use of a centralized and Medicare-covered TM vendor utilizing a developed methodology and established organizational infrastructure offers the great potential for a rapid rollout to increase access to MOUD and improve treatment retention in rural areas. This cluster randomized clinical trial with two phases will test expanded treatment access to improve retention on MOUD in highly affected rural areas. Phase I will include implementing telemedicine in a limited number of rural sites with varying levels of office-based opioid treatment (OBOT) to inform implementation strategies for the main trial, and Phase II will include evaluate comparative effectiveness between OBOT alone and OBOT + TM at 30 sites.

1-Year Sustained Release Naltrexone Implant for the prevention of relapse to opioid dependence Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA Delpor, Inc. Martin, Francis South San Francisco, CA 2019
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:

There is a need for longer-acting prophylactic pharmacologic options for opioid use disorder (OUD) patients during maintenance therapy. This study tests a titanium implant loaded with a formulation of naltrexone and a naturally occurring carboxylic acid. The device is implanted subcutaneously with local anesthetic during an in-office procedure. The technology is based on a unique formulation that keeps the pH within the reservoir low and promotes passive diffusion of naltrexone. The benefits of the product include complete medication adherence for one year after administration, fewer relapses, smooth profile ensuring complete prophylaxis without sub-therapeutic plasma troughs, full reversibility, and similar efficacy with less drug exposure. This technology has been validated clinically with another drug and tested preclinically with naltrexone. This project will finalize the chemistry manufacturing and controls, produce IND supplies, conduct an IND-enabling safety study, and submit the IND.

Mobile Augmented Screening Tool to Increase Adolescent HIV Testing and Linkage to Care Cross-Cutting Research Small Business Programs NIDA DIGITAL HEALTH EMPOWERMENT, INC. ARONSON, IAN DAVID BROOKLYN, NY 2019
NOFO Title: PHS 2016-02 Omnibus Solicitation of the NIH, CDC, FDA, and ACF for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44])
NOFO Number: PA-16-302
Summary:

Adolescents face increased HIV risk, infrequent testing, inconsistent linkage to care, and a lack of prevention-related knowledge. We propose to complete and evaluate the Mobile Augmented Screening (MAS) tool to privately and discretely offer routine HIV testing and counseling, including prevention education, to high-need, diverse adolescent and young adult populations at a low cost. The MAS will consist of a tablet-based intervention including a brief video designed to increase adolescent HIV testing, automated text messages to facilitate linkage to care for those who test positive, and text-based education for those who test negative or decline testing. Phase I was conducted with young emergency department (ED) patients. Preliminary evaluations indicate the video led to significant knowledge increases and encouraged testing. In phase II, we seek to complete intervention development and evaluate through a randomized controlled trial with ED patients, with qualitative interviews for a subset of young patients and ED staff.

NOFO Title: PHS 2018-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Technology Transfer Grant Applications (Parent STTR [R41/R42] Clinical Trial Not Allowed)
NOFO Number: PA-18-575
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.

Immune Modulating Therapies to Treat Complex Regional Pain Syndrome Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS DREXEL UNIVERSITY AJIT, SEENA Philadelphia, PA 2022
NOFO Title: HEAL Initiative: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: NS22-034
Summary:

Complex regional pain syndrome is a difficult-to-treat chronic condition that causes excess and prolonged pain and inflammation after injury to an arm or leg and includes damage to skin of affected limbs. Although it is known that aberrant immune system function plays a role in this condition, the details remain unclear about how this occurs – in particular, through the adaptive immune system that relies on specialized immune cells and antibodies to protect the body from harm.  This project will study the role of certain immune cells (T cells) that circulate throughout the body or reside in bone using both rat or human bone samples from patients with complex regional pain syndrome.

MECHANISMS OF MUSIC THERAPY TO PALLIATE PAIN IN PATIENTS WITH ADVANCED CANCER Clinical Research in Pain Management NINR DREXEL UNIVERSITY BRADT, JOKE Philadelphia, PA 2018
NOFO Title: Arts-Based Approaches in Palliative Care for Symptom Management (R01)
NOFO Number: PAR-14-294
Summary:

This study addresses the public health problem of chronic pain as one of the most feared symptoms in people with cancer. Insufficient relief from pharmacological treatments and the fear of side effects are important reasons for the growing use of complementary pain management approaches in people with cancer. One such approach is music therapy. Although efficacy of music therapy for pain has been established, there are no mechanistic studies clarifying how it works in clinical populations. The overarching goals of this study are to 1) examine mediators and moderators hypothesized to account for the pain-reducing effects of interactive music therapy (IMT) in people with advanced cancer and chronic pain and 2) validate IMT’s theory of action. The results of this study will provide estimated effects sizes of IMT on the mediators and preliminary effect size estimates for the pain outcomes. This information will be instrumental in the development of a subsequent large-scale efficacy trial.

Regulation of neuropathic pain by exercise: effects on nociceptor plasticity and inflammation Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS DREXEL UNIVERSITY DETLOFF, MEGAN R Philadelphia, PA 2018
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Spinal cord injury (SCI) impairs sensory transmission leading to chronic, debilitating neuropathic pain. While our understanding of the molecular basis underlying the development of chronic pain has improved, the available therapeutics provide limited relief. In the lab, we have shown the timing of exercise is critical to meaningful sensory recovery. Early administration of a sustained locomotor exercise program in spinal cord–injured rats prevents the development of neuropathic pain, while delaying similar locomotor training until pain was established was ineffective at ameliorating it. The time elapsed since the injury occurred also indicates the degree of inflammation in the dorsal horn. We have previously shown that chronic SCI and the development of neuropathic pain correspond with robust increases in microglial activation and the levels of pro-inflammatory cytokines. This proposal seeks to lengthen the therapeutic window where rehabilitative exercise can successfully suppress neuropathic pain by pharmacologically reducing inflammation in dorsal root ganglia.

VALIDATION OF TARGETING MACROPHAGE-MEDIATED EVENTS IN THE DRG TO ALLEVIATE CHRONIC SPINAL CORD INJURY PAIN Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS DREXEL UNIVERSITY DETLOFF, MEGAN R PHILADELPHIA, PA 2019
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

Spinal cord injury (SCI) impairs sensory transmission and leads to chronic, debilitating neuropathic pain. While our understanding of the development of chronic pain has improved, the available therapeutics provide limited relief. We will examine the peripheral immune and inflammatory response. Secondary inflammation in response to SCI is a series of temporally ordered events: an acute, transient upregulation of chemokines, followed by the recruitment of monocytes/macrophages and generation of an inflammatory environment at the lesion site in the spinal cord, but also surrounding primary nociceptors in the dorsal root ganglia (DRG). These events precede neuropathic pain development. Previous work indicates that after SCI, macrophage presence in the DRG correlates with neuropathic pain. We propose to study: 1) whether the phenotype of macrophages that infiltrate the DRG is different than those that persist chronically after SCI and 2) how manipulation of macrophage phenotype affects nociceptor activity and pain development.

A Long-Acting Bioabsorbable Naltrexone Subcutaneous Implant for Opioid Use Disorder Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA DRUG DELIVERY COMPANY, LLC, THE COHEN, STEVEN M; BENNER, JEFFREY Salisbury, MD 2019
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:

Naltrexone (NTX) has proven to be an important, safe, and effective therapy for helping patients overcome opioid use disorders (OUD) and for preventing overdose. Unfortunately, the therapeutic potential of NTX has been blunted by poor adherence. To combat this issue, a system must be developed to deliver NTX for longer durations than currently available and with a more patient-friendly format. To address this problem, we will develop a long-acting and bioabsorbable NTX subcutaneous implant for the treatment of OUD. The proposed research will (a) determine the optimal chemical preparation of NTX inside the implant, (b) optimize the composition and porosity of the drug delivery substrate, and (c) refine the surgical procedure and instrumentation to be used during implantation. Once the safety and efficacy of this novel NTX implant is established, we will conduct the necessary clinical trials. The proposed study is highly relevant to and complementary of other efforts, either in consideration or already deployed to stem the tide of the lingering opioid crisis. If successful, this solution has the potential to enhance health, lengthen life, and reduce illness and disability for those suffering from OUD.

NOFO Number: RFA-NS-19-025
Summary:

Managing persistent pain has long been a difficult challenge, one that is heightened by the recent opioid crisis. Although many potential solutions may exist, demonstrating their efficacy in a multicenter trial is a considerable obstacle. There is broad consensus that a nationwide clinical research network is necessary to promote innovation. A hub-spoke complex of academic medical centers with considerable experience in pain management clinical trials and biomarker validation will leverage existing resources to make clinical trial execution efficient and rapid. Together, spokes will provide maximum flexibility, ready to accommodate studies in any well-characterized pain condition.
