The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT04011124
Recruitment Status : Completed
First Posted : July 8, 2019
Last Update Posted : February 26, 2020

Brief Summary:

The primary objective of the study was to assess the effect of repeated oral doses of Rifampicin on the pharmacokinetic profile of a single dose of Fluzoparib.

The secondary objective of the study was to assess the safety of Fluzoparib given alone versus Fluzoparib coadministered with Rifampicin.
