Study Summary

This will be a Phase 1, open label, 2-sequence, crossover study to establish the BE of the current commercial formulation (Generation 3.1 talazoparib capsules) to the proposed talazoparib liquid-filled soft gelatin capsule (soft gel capsule) formulation after multiple dosing under fasting conditions in participants with advanced solid tumors. In addition, the effect of food on the PK of the proposed talazoparib soft gel capsule formulation will be evaluated in fixed sequence after the 2 BE assessment periods.

Primary Outcome

AUC24 was defined as area under the plasma concentration-time profile from time zero to 24 hours post dose. The geometric coefficient of variation is expressed in percentage. The ratio (Test/Reference) of adjusted means and 90% CI were expressed as percentages.
