A Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamic Effects of KUR-101 in Healthy Adults

This project tests the safety, tolerability, pharmacokinetics (PK, the amount of study drug in your blood) and pharmacodynamics (PD, how the study drug affects your body) of single doses of KUR-101 in 58 healthy participants.

This is a Phase I trial from atai Life Sciences. KUR-101 is an oral formulation of mitragynine, an alkaloid derived from the kratom plant. atai hopes that KUR-101 will effectively treat opioid use disorder (OUD) patients.

Trial Details

This study is divided into two parts: Part 1 is a randomized, double-blind, placebo-controlled study to assess the safety, tolerability, PK, analgesic and respiratory effects of single ascending doses of orally administered KUR-101 in normal healthy participants. Once the MTD has been determined, this dose, or an alternate lower dose, will be taken into Part 2 of the study. This part will involve a single ascending (increasing) dose (SAD) where 40 participants (5 groups of 8) will be randomised (assigned randomly, like flipping a coin) to receive a single oral dose of the study drug or placebo. Part 2 is a randomized, double-blind, placebo-controlled, three-period crossover study to assess the analgesic and respiratory effects of a single oral KUR-101 as compared to that of oxycodone in normal healthy participants. This part will involve a crossover design where 18 participants will be randomised to receive a single oral dose of each of three interventions (study drug, placebo or a marketed form of oxycodone). Each dose is separated by 7 days and the participants are randomised so they do not know the order of the interventions.
