Assess the Drug Interactions of BBT-877 and Midazolam, Itraconazole, and Esomeprazole in Healthy Adult Subjects

Phase 1

Completed

• Conditions: Healthy Participants
• Interventions: Drug: BBT-877; Drug: Itraconazole; Drug: Midazolam; Drug: Esomeprazole

• Registration Number: NCT04138836
• Lead Sponsor: Bridge Biotherapeutics, Inc.

Brief Summary

Study to determine the effect of multiple-dose BBT-877 on the single-dose pharmacokinetics of midazolam, the safety and tolerability of a single dose of BBT-877 administered alone and with multiple doses of itraconazole, and the effect of multiple-dose esomeprazole on the single-dose pharmacokinetics of BBT-877, in healthy adult subjects.
