Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

3-way cross-over single dose design evaluating bioavailability of 2 rifampicin-containing FDCs vs a single drug comparator in healthy volunteers

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study the 4- and 2-drug FDCs (for intensive and continuation phases respectively) widely used within the South African treatment program will be evaluated in a comparative bioavailability study against a single drug rifampicin product registered by the South African Medicines Control Council. A three-way, single dose, cross-over study will be conducted in 24 healthy volunteers
