a study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamic effects of kur-101 in healthy adults

Conditions: Acute Pain

Summary: this project is testing 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 a new drug called kur-101. up to 58 healthy men or women aged between 18-55 will be enrolled in this study in two parts. part 1 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. the placebo will look the same as the study drug but will not contain any medicine. part 2: 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. for part 1 the total participation will last 9 days, of which 4 days (3 nights) will be spent in the clinic. one group of subjects in part 1 will return to the clinic to receive a second dose of drug given with a high fat breakfast. in this group, the total participation will last 16 days, of which 8 days (7 nights) will be spent in the clinic. for part 2 the total participation will last 23 days, of which 9 days (8 nights) will be spent in the clinic.

this is a phase 1, single-center, prospective, study of orally administered kur-101 in normal healthy participants. the study will be conducted in 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. 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.
