Effect of Food and Age on the Pharmacokinetics of LY03017

A Phase 1 Study to Evaluate the Effect of Food and Age on the Pharmacokinetics of LPM526000133 Fumarate Capsules (LY03017) in Healthy Volunteers

This study consists of 2 parts. Part A is a randomized, open-label, 2-period, crossover study to evaluate the food effect of LY03017 in healthy adults. Part B is a single-arm study to evaluate the safety and pharmacokinetics of LY03017 in elderly volunteers.
