Cobenfy to help reduce cocaine use

Official title: Evaluation of the Combination Muscarinic Cholinergic Receptor Drug Product Cobenfy as a Medication for Cocaine Use Disorder Using Translational Human and Rat Cocaine Choice Procedures

Funded at University of Kentucky · NIH-11274817 · Data updated 2026-11-12

People with cocaine use disorder will try the medication Cobenfy to see whether it helps them choose money instead of cocaine.

Who could benefit from this research

Could help

Adults with diagnosed cocaine use disorder who are medically stable and willing to stay as inpatients for controlled cocaine-versus-money choice sessions would be eligible.

Less likely to help

People who are pregnant, have unstable medical or serious psychiatric conditions, significant heart disease, or who cannot or will not be inpatient or receive controlled IV cocaine are unlikely to benefit or be eligible.

What this research studies

You would stay as an inpatient and be given Cobenfy or a placebo until the medication reaches steady levels, then take part in controlled sessions where you choose between small amounts of IV cocaine or money. The same choice procedures will be run in rats to compare effects across species and strengthen predictions for people. Cobenfy combines xanomeline (which acts on brain muscarinic receptors) with trospium (which reduces peripheral side effects) and is already FDA-approved for schizophrenia. Researchers will compare choices to determine whether the medication shifts preference away from cocaine toward non-drug rewards.

Why it matters

Potential benefit: If successful, Cobenfy could help people with cocaine use disorder reduce their cocaine use and favor non-drug rewards, offering a new medication option.

How similar studies have gone: Prior animal studies showed that xanomeline reduced cocaine-related behaviors, but testing Cobenfy in people for cocaine use disorder is a new clinical translation.
