Funded Projects

Sickle cell disease is an inherited blood disorder affecting about 100,000 Americans and more than 20 million people worldwide. It is caused by a mutation in the gene for beta-globin that results in the characteristic sickled shape of red blood cells, life-long severe pain, and shortened lifespan. Optimal treatment of  chronic pain from the condition targets psychological factors contributing to pain, such as pain-related anxiety, fear of movement, and depression. This project will interact with patients and their families to revise and test an existing mind–body and behavioral health treatment tool to target the unique needs and preferences of people managing chronic sickle cell disease pain.

Asian American women who have survived breast cancer and who also have depression are less likely to receive adequate pain treatment due to cultural stigma attached to breast cancer, cultural attitudes about living with pain and symptoms, and language barriers. This project will use a personalizable, technology-based approach to treat cancer pain and depression in Japanese American, Chinese American, and Korean American women who have survived breast cancer. The intervention will accommodate flexibility, accessibility, and anonymity: three factors that have historically hindered effective pain management for this population of breast cancer survivors.

Back pain, including low back and neck pain, is one of the most prevalent and disabling pain disorders. Treatment requires ongoing self-management, but most healthcare systems do not support self-care and instead focus on costly, provider-dependent therapies that remain inaccessible to many Black and Hispanic Americans and individuals with less education and income. This project will address these health disparities by developing a personalized self-management treatment program that includes pain education, mindfulness, cognitive behavioral therapy, and exercise – and make it available in community settings.

Temporomandibular joint (TMJ) disorders, which affect the joint connecting the lower jaw and the skull, are common and difficult chronic pain conditions. Pain management strategies that harness the body’s own pain relief mechanisms (including placebo effects in which pain relief cannot be attributed to a specific treatment), can reduce the severity and duration of TMJ-related chronic pain. Although research suggests that placebo effects may have a genetic basis, few, if any, genetic studies have examined this possibility in individuals with TMJ disorders. This project will use in-depth genetic, sociodemographic, clinical, and psychological data collected from adults with chronic TMJ disorders to better understand how the placebo effect works.

Sickle cell disease is an inherited blood disorder affecting about 100,000 Americans and more than 20 million people worldwide. It is caused by a mutation in the gene for beta-globin that results in the characteristic sickled shape of red blood cells, life-long severe pain, and shortened lifespan. Sickle cell disease pain episodes are usually unanticipated, making it hard for people with the condition to manage their pain and putting them at risk for increased use of opioids and poor health outcomes. This project will use existing real-time health data to identify factors that can predict onset, severity, and worsening of daily pain in children with sickle cell disease.

It is unclear if long-term use of opioids by head and neck cancer patients affects risk for depression, which is higher in this population compared to people without cancer. This knowledge could inform interventions such as increased opioid prescription safety or alternative pain management approaches and could thus help reduce the risk for depression-related outcomes. This project will use data from a national cancer database linked to Medicare claims and a Veterans Administration database to determine whether people with head and neck cancer that take opioid medications for more than 90 days have increased risk for new-onset or worsening depression or suicide death.

Musculoskeletal pain is common, costly, and affects millions of Americans. Clinical guidelines strongly recommend complementary and integrative treatments such as physical therapy, but nearly half of people receiving physical therapy for musculoskeletal pain seek additional care. Additional treatments such as medication and surgery are more aggressive and carry higher risk. This project will use data from a large physical therapy dataset and nationwide medical claims data to investigate why some people do not respond well to physical therapy for musculoskeletal pain, toward finding safe and effective options for these individuals.

This project will develop and refine a wearable device (forearm bracelet) designed to rapidly sense and report the presence of opioids in the wearer. This research will optimize this device to provide ultra-high sensitivity, enhanced drug specificity, long-term durability, low power consumption, and cost-effective production. The findings could support a path toward commercialization of this new device.

This project will refine an experimental non-invasive light therapy to create an effective, safe, convenient, and affordable method for treating opioid use disorder. This research will test whether a short treatment of near infra-red light administered through the skull can reduce drug use, relapse, and craving, and improve overall function in people with opioid use disorder. If effective, the findings could support a path toward commercialization of this new treatment.

Naltrexone is the only medication approved by the U.S. Food and Drug Administration to prevent relapse from opioid use disorder. This medication remains underused because it must be injected into muscle by a nurse and is relatively expensive. This project will develop and test a novel naltrexone skin patch that is easier to use, more comfortable, and inexpensive.

Currently no medications are approved by the U.S. Food and Drug Administration for psychostimulant (cocaine and methamphetamine) use disorder. This project will develop a novel opioid molecule (PPL-138) that blocks cocaine and methamphetamine self-administration in animal models and that lacks rewarding properties that could lead to addiction. This research will conduct manufacturing and safety studies to prepare for Phase 1 clinical trials to determine safety in human patients.

Many people intending to take medications for opioid use disorder, including buprenorphine, as part of their recovery pathway do not stay in treatment long enough to reduce risk for overdose. These individuals also often continue to use one or more other drugs during treatment, which may further raise their overdose risk. This project will develop and conduct a preliminary test of an innovative integrated intervention that combines buprenorphine treatment with recovery coaching and online cognitive behavioral therapy. This research will assess whether the approach reduces drug use during buprenorphine treatment and helps people stay in treatment longer.

The science of recovery support services for individuals choosing to take medications for opioid use disorder as part of their recovery pathway is gaining momentum and will benefit from a dedicated, sustainable cross-project research infrastructure. This project enhances research in the existing Consortium on Addiction Recovery Research Science. This effort coordinates varied research and training efforts across recovery support research projects, amplifies communication and dissemination channels for their activities, and is organizing the first national meetings on addiction recovery support services science.
