Dronabinol as an Adjunct for Reducing Pain

This exploratory, proof-of-concept study is a double-blind (participants and investigators will be blinded), placebo-controlled, randomized, two-arm clinical trial of Marinol \[dronabinol, synthetic Δ9-tetrahydrocannabinol (THC)\] for chronic low back pain (cLBP) with a 2:1 allocation ratio. Up to 75 subjects will be enrolled in this pilot study and randomized to receive doses of THC (up to 30 mg/day), orally, over 8 weeks. This study will be conducted at a single site; it does not include any stratifications, and there is no interim analysis planned. Notably, the goal is to determine whether there is enough evidence of the safety of THC to support the development of later-phase clinical trials. Thus, detailed developmental plans are contingent on the outcomes of this study.

Evaluation of the Safety and Effects of Psychoactive Substances in People With Past Opioid Use

The purpose of this study is to understand how kratom affects people. In this study, kratom will be compared with another substance and a placebo (an inactive substance). Researchers will also study how the substances move through and affect the body. This includes examining how the body absorbs, processes, and eliminates the drug (pharmacokinetics), as well as how the drug affects the body and how it may make you feel (pharmacodynamics). The information collected will help researchers better understand the effects and potential risks of kratom.
