About this study

The purpose of this study is to understand the relative amount of drug that enters bloodstream from prifetrastat product lots differing in active ingredient particle size distribution. The study is seeking participants who are: Healthy males and females of non-childbearing potential \>=18 years of age at screening Participants in the study will receive a single dose of prifetrastat by mouth. After at least 14 days, they will receive another dose of prifetrastat by mouth. Each dose received by the patient will be in tablet form. The sequence in which tablets are given will be random. The study will help understand how the difference in particle size distributions of the tablets may, or may not, affect how the drug is absorbed, processed, and eliminated by the body. Participants will remain in the study clinic for 21 days. However, they may be permitted to leave between periods, and will have one follow-up contact.
