TASK-002: Bioequivalence of Bedaquiline 400mg Administered in Crushed Form Compared to Tablet Form in Healthy Male and Female Adults Under Fed Conditions (BDQ Crush Study)
Study Details
Study Description
Brief Summary
This is a randomized, open-label, cross-over study comparing the bioequivalence of bedaquiline administered in whole tablet form versus bedaquiline administered in crushed (experimental) form in healthy adult volunteers.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Early Phase 1 |
Detailed Description
This is a randomized, open-label, cross-over, bioequivalence study with two single treatment periods, separated by a 14-day wash-out period, conducted among 24 healthy adult males and females, who receive 400mg (4 x 100mg) bedaquiline orally in one of two sequences: either first in whole tablet form and second in crushed (experimental) form, or vice versa under fed conditions. The bioequivalence evaluation will be based on primary pharmacokinetic (pk) parameters affecting the extent of absorption, i.e., the bioavailability. If bioequivalence is not shown, the knowledge about the differences in bioavailability between whole and crushed tablets will be used for assessing the need of dose adjustment in children receiving the crushed form.

Outcome Measures
Primary Outcome Measures
- Bioequivalence of bedaquiline 4 x 100mg given to healthy adult males and females orally in tablet form compared to crushed form [Two single treatment sequences, separated by a 14-day wash-out period]
The bioequivalence evaluation will be based on primary PK parameters affecting the extent of absorption, i.e. the bioavailability.
