Funded Projects

The Planning for the HEALthy Early Development Study will contribute to the design and recommended protocol for a future large-scale, multi-site research study to prospectively examine human brain, cognitive, behavioral, social, and emotional development of children beginning prenatally through ages 9–10 and to determine the impact of maternal pre- and postnatal substance use on short- and long-term development of children. The planning study will link investigators across 6 research sites who have complementary experience and expertise in the areas that are essential to designing the study. Planning activities will be accomplished using a coordinated set of 10 working groups. By the end of the planning phase, the 6 consortium sites will have produced and tested a recommended protocol for the future multi-site study and will have established feasibility of carrying out the study protocol at each of the 6 linked sites.

Patients who use both opioids and methamphetamine often experience serious medical complications requiring hospitalization. While hospitalization provides an opportunity to start addiction treatment, linking patients to outpatient treatment after discharge is hard. This project will develop and conduct a pilot trial of an intervention that combines patient navigation with a mobile app offering financial incentives for outpatient treatment. This research will also develop outcome measures to describe participants’ use of healthcare and how it is influenced by baseline methamphetamine use. If effective, this patient-navigator-plus-mHealth approach could help reduce substantial gaps in treatment and retention for people who use opioids and methamphetamines simultaneously.

Young adults (18 to 26) with a substance use problem have the highest rates of polysubstance use among all age groups. At the same time, individuals in this age group (especially in rural areas) are generally lacking in recovery capital: resources to help them recover from substance use, such as vocational or educational skills. This project will assess the feasibility and acceptability of “Launch,” which uses parental and peer recovery support to increase recovery capital for young adults with polysubstance use. The intervention will use coaching as well as contingency management, a treatment approach in which individuals receive tangible rewards as incentives for desired behaviors such as abstinence. If successful, the findings will inform a future large-scale trial assessing the effectiveness of this approach.

Compared to people who use only one type of drug, people who use combinations of drugs, such as opioids and stimulants, are more likely to have histories of childhood trauma, including post-traumatic stress disorder (PTSD). This project will adapt an existing PTSD intervention, Skills Training in Affective and Interpersonal Regulation with Narrative Therapy, to treat individuals with polysubstance use. This research will be piloted in a methadone maintenance treatment program to assess feasibility and acceptability. If successful, the findings will lay the groundwork for a large-scale clinical trial.

Pain caused by the degeneration of discs between vertebrae in the spine makes up a significant proportion of all chronic low back pain conditions. Although opioids are prescribed as treatments for this chronic condition, they often do not provide effective pain management, and currently there are no treatments that target the underlying disc disease. Notochordal cells mature into the cells that make up discs between vertebrae. Preliminary studies have shown that notochordal cells can be made from induced pluripotent stem cells, offering a potential replacement for diseased cells between discs. This study aims to develop a novel treatment for painful disc degeneration using a microgel/microtissue embedded with human notochordal cells made in the lab from induced pluripotent stem cells.

More than 700,000 total knee replacement surgeries are performed each year in the United States to relieve joint pain in patients with end-stage osteoarthritis or rheumatic arthritis. However, many patients still experience significant pain after this procedure, calling for additional long-lasting, drug-free pain management strategies. This project will develop and test a commercial prototype device for persistent knee pain after total knee replacement. The injection-based method freezes peripheral nerves to reduce pain sensation.

A critical line of defense against opioid use disorder (OUD), one of the nation’s leading preventable causes of death, must be standardized screening provided by the patient’s primary care physician, psychiatrist, and/or counselor. Standardized screening methods for opioids, however, are simply inferior and no gold standards exist. This project aims to develop a validated, theoretically guided tool that provides clinicians with information beyond OUD symptoms using reinforcer pathology, a measure of severity derived from the synergy between excessive delay discounting and high behavioral economic demand. The Behavioral Economic Screening Tool (BEST-OUD) will use these combined measures in a mobile tablet application to enable clinicians to screen for OUD.

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.

Most of the 200k Americans who undergo thoracotomy each year receive opiates to reduce postoperative pain because clinicians have few non-addictive, cost-effective choices to control the severe pain patients often experience in the first two weeks after surgery. Managing pain post-thoracotomy is critical to enable patients to take deep breaths and remove (via coughing) lung secretions that otherwise significantly increase risk of pneumonia and collapsed lung, hospital re-admission and morbidity. The most severe pain associated with thoracotomy is transmitted along the intercostal nerves, but no long-term analgesic or nerve block device exists that can provide safe and effective long-term reduction of pain. A reversible, patient-controlled, non- addictive, intercostal nerve block device would reduce suffering due to thoracotomy, broken ribs and herpes zoster. In this Phase I project, the team will develop a minimally invasive thermal nerve block device that can control nerve conduction by gently warming and cooling a short nerve segment between room temperature and warm water temperature. This novel approach is based on the discovery that warm and cool temperature mechanisms of nerve block are different and additive, enabling moderate-temperature nerve block by cycling neural tissues slightly above and below body temperature. Reversible thermal nerve blocks represent a completely new approach to managing pain.  

The need to develop non-opioid therapeutics for chronic pain is greater than ever.  One option being explored is inhibiting the activity of calpains – enzymes that have been shown to cause pain in animal models of chronic pain.  Using an artificial intelligence (AI)-driven drug discovery platform, researchers have uncovered and validated four calpain-1 inhibitors using biochemical assays.  This study by 1910 Genetics Inc. hopes to synthesize multiple analogs of its most potent discovered calpain-1 inhibitor and determine its effectiveness against calpain-2 and certain enzymes that break down proteins.  Findings that successfully significantly inhibit calpain-1 in at least one animal model of chronic pain could lead to the first oral, central nervous system penetrating selective calpain-1 inhibitor [non-opioid therapeutic] for chronic pain.

Nerve stimulators are devices surgically implanted near a peripheral nerve or on the spinal cord that use electrical signals to reduce the perception of pain. Although these devices can provide effective pain relief to patients, many have high complication rates, resulting from the wire moving, breaking, not working, or the implantable battery pack or permanent wire causing new pain. This project will support the development and animal testing of a peripheral nerve stimulator to treat chronic pain which can be implanted without surgery. Once injected, the device will provide pain relief through electrical stimulation and then be safely degraded and resorbed by the body.

 Investigating the broader efficacy of sEH inhibition and specifically our IND candidate, EC5026, has indicated that it is efficacious against chemotherapy induced peripheral neuropathy (CIPN). This painful neuropathy develops from chemotherapy treatment, is notoriously difficult to treat, and can lead to discontinuation of life-prolonging cancer treatments. Thus, new therapeutic approaches are urgently needed. The research team will investigate if EC5026 has potential drug-drug interaction with approved chemotherapeutics or alters immune cells function, and assess the effects of sEHI on the lipid metabolome and probe for changes in endoplasmic reticulum stress and axonal outgrowth in neurons. The team proposes to more fully characterize the analgesic potential of our compound and investigate on and off target actions in CIPN models and model systems relevant to cancer therapy.
