Overview
Brief Summary
This is a multiple part, multiple cohort study evaluating the relative bioavailability, food effect, and drug-drug interaction of NX-5948 in healthy volunteers.
Detailed Description
In Cohort 1, Period 1 volunteers will receive NX-5948 in a tablet form under fasting conditions. In Period 2, volunteers will receive NX-5948 in a capsule form under fasting conditions. In Period 3, volunteers will receive NX-5948 in a tablet form under fed conditions. In Cohort 2, Period 1 volunteers will receive NX-5948 in a capsule form under fasting conditions. In Period 2, volunteers will receive NX-5948 in a tablet form under fasting conditions. In Period 3, esomeprazole will be administered once daily for 5 consecutive days with a single dose of NX-5948 tablet coadministered on Day 5. In both cohorts, serial blood samples will be collected to assess PK.
