Summary:

Chemotherapy-induced painful peripheral neuropathy (CIPN) is the most common toxicity associated with widely used chemotherapeutics. CIPN accounts for significant dose reductions and/or discontinuation of these life-saving treatments. Unfortunately CIPN can also persist in cancer-survivors, adversely affecting their quality of life. CIPN is not well-managed with existing pain therapeutics. Recent preliminary findings suggest that the transcription factor hypoxia-inducible factor alpha (HIF1A) is the target for the chemotherapeutic bortezomib, a proteasome inhibitor. This project will test the hypothesis that bortezomib chemotherapy-induced expression of HIF1A, PDHK1 and LDHA constitute an altered metabolic state known as aerobic glycolysis (AG) that leads to the initiation and maintenance of peripheral neuropathy and pain using a novel tumor-bearing animal model of CIPN. This project aims to validate HIF1A as a therapeutic target for the prevention of CIPN, as well as validate PDHK1 and LDHA as non-opioid therapeutic targets for chronic or established CIPN in animal models.

Summary:

Often (around 40 percent of the time), individuals being treated for opioid use disorder (OUD) also have pain that interferes with daily life. This study builds on the prior development of a collaborative primary care approach, entitled TOPPS (Treating Opioid Patients’ Pain and Sadness), in which behavioral health specialists and primary care providers share a unified plan for addressing pain and depression in patients receiving buprenorphine. Building in preliminary work, researchers are conducting a randomized controlled trial of TOPPS compared to a health education contact-control condition among 250 persons with OUD recruited from two primary care-based buprenorphine programs, provided over 3 months and followed over 12 months. The study will examine whether this intervention changes how much pain interferes with daily functioning, the severity of pain, depression, and whether individuals stay in OUD treatment.

Summary:

Opioids remain the gold standard for treating moderate to severe pain, but their use is limited by numerous adverse effects, including tolerance, dependence, abuse, and overdose. Adverse effects could be avoided by combining an opioid with another drug, such that smaller doses of the opioid (in combination with another drug) produce the desired therapeutic effect. Direct-acting serotonin type 2 (5-HT2) receptor agonists interact in a synergistic manner with the opioid morphine to produce antinociceptive effects, suggesting a 5-HT2 receptor agonist could be combined with small amounts of an opioid to treat pain, thereby lowering the risk associated with larger doses. Unfortunately, very little is known about interactions between 5-HT2 receptor agonists and other opioids. The proposed studies will evaluate the therapeutic potential of mixtures of opioids and 5-HT2 receptor agonists using highly translatable and well-established procedures to characterize the antinociceptive, respiratory-depressant (overdose), positive-reinforcing (leading to misuse), and discriminative-stimulus (subjective) effects of drug mixtures as well as the impact of chronic treatment on the development of tolerance to and physical dependence on opioids. If successful, these studies will provide proof-of-concept for this innovative approach to pain treatment and evaluate the utility of targeting 5-HT receptors for analgesic drug development.
1R01DA047094-01A1 Guanfacine Target Engagement and Validation to Improve Substance Use Outcomes in Women Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA YALE UNIVERSITY Sinha, Rajita New Haven, CT 2019
NOFO Title: NIH Research Project Grant (Parent R01 Clinical Trial Required)
NOFO Number: PA-18-345
Summary:

There are currently no FDA-approved treatments for cocaine use disorder (CUD) or co-occurring substance use disorder. High relapse rates pose a major obstacle to treatment, and this is due in part to the way that high drug cravings reduce individuals’ cognitive flexibility in situations where they are stressed or exposed to drug-related cues. These effects appear to be stronger in women with CUD than in men. Building on preliminary data that a drug called Guanfacine reverses these effects in women, but not in men, this 3-year pilot clinical study will test whether Guanfacine will reduce cocaine use and increase abstinence and will use laboratory challenges to determine whether it reduces cravings and enhances cognitive flexibility in stressful or drug-cue-related situations.

Summary:

The ongoing opioid crisis has led to renewed concerns about the clinical prescription of addictive opioid analgesics. However, there are currently no suitable alternatives for treating severe or malignant pain. Studies of opioid signaling mechanisms in mice deficient in ?-arrestin have suggested that biased agonists displaying preferential activation of G-protein signaling over ?-arrestin signaling could offer a promising avenue for the development of opioid analgesics with a reduced adverse effects profile. However, there is no concluding evidence showing that such biased signaling can indeed be associated with reduced opioid side effects and, consequently, an improved safety profile. This research will address the need for preclinical data to rigorously evaluate this hypothesis with a program of in vivo studies to compare the effects of “balanced” opioids (morphine, oxycodone, and fentanyl) with that of the “biased” agonists PZM21 and two novel ligands provided by colleagues at the NIDA IRP in nonhuman primates. The results of these studies will provide critical information regarding the dependence liability of “biased” agonists that, in clinical practice, might be given on a repeated, or chronic, basis, potentially adding a powerful new tool for the safer management of severe or malignant pain.
