Trial Summary

What is the purpose of this trial?

This is a 2-cohort, fixed-sequence, 3-period, relative bioavailability, food-effect, and drug-drug interaction study. It is an open-label study evaluating the relative bioavailability of NX-5948 tablets compared to capsules, and the effect of food and an acid-reducing agent on the pharmacokinetics (PK) of NX-5948.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it requires participants to be medically healthy with no significant medical history. This suggests that participants should not be on any regular medications for ongoing health issues.
