A Study to Assess the Effect of Food on the Pharmacokinetics of TY-9591 in Healthy Volunteers

TYK Medicines, Inc16 enrolled

Overview

To assess the pharmacokinetics of TY-9591 tablets and Osimertinib Mesylate tablets after a single fasting administration and the effect of food on the pharmacokinetics of TY-9591 tablets in healthy volunteers.

This is a single center, randomized, open label, two phases study in healthy adult volunteers. The first phase is a two-sequence, two-period crossover trial. The volunteers will be randomly distributed into two groups and given either TY-9591 tablets or Osimertinib Mesylate tablets on a single fasting administration. In the second phase, all volunteers will be administrated TY-9591 tablets after a high fat meal. The washout between each treatment is no less than 21 days.
