Clinical Trials

Several Phase 1 clinical trials have evaluated ABX-1431 to assess its safety, tolerability, and preliminary efficacy across neurological and pain-related conditions. Sponsored by Abide Therapeutics with academic collaboration from the University of Oxford, these studies investigated the compound in peripheral neuropathic pain, central pain conditions such as multiple sclerosis and neuromyelitis optica spectrum disorder, tic disorders including Tourette syndrome, and experimental hyperalgesia in healthy volunteers using functional magnetic resonance imaging. All of these trials have reached completed recruitment status.

Compliance for Clinical Use

Mechanism and Biochemical Profile

ABX-1431 selectively binds to and inhibits central nervous system monoacylglycerol lipase (MGLL), preventing the enzymatic degradation of the endocannabinoid 2-arachidonoylglycerol and subsequently enhancing signaling through cannabinoid receptors. This elevated endocannabinoid tone modulates neurotransmission and nociceptive signaling pathways, providing a mechanistic basis for mitigating pain and hyperkinesia in clinical conditions such as neuropathic pain and Tourette syndrome.
