A Study to Evaluate Novel KarX and KarT Prototypes Versus the KarXT and KarX-EC Reference Following Single Doses, Explore the Effect of Food After Multiple Doses of Selected Prototypes, and Evaluate Alternative Formulations of KarX and KarXT Following Single and Multiple Ascending Doses

Phase 1, 4-Part, Open-label (Parts 1 to 3) and Double-blind (Part 4) Study to Evaluate the Pharmacokinetics of Novel KarX (BMS-986519) and KarT (BMS-986520) Prototypes Versus the KarXT (BMS-986510) and KarX-EC (BMS-986519) Reference Following Single Doses, and to Explore the Effect of Food After Multiple Doses of Selected Prototypes in Healthy Adult Participants, and to Evaluate Alternative Formulations of KarX (BMS-986519) and KarXT (BMS-986510) Following Single and Multiple Ascending Doses in Healthy Adult Participants

Brief summary

The purpose of this study is to evaluate novel KarX and KarT prototypes versus the KarXT and KarX-EC reference following single doses, to explore the effect of food after multiple doses of selected prototypes, and to evaluate alternative formulations of KarX and KarXT following single and multiple ascending doses in healthy adult participants.
