A Phase I Study of Talazoparib and Consolidative Thoracic Radiotherapy for Extensive Stage Small Cell Lung Cancer

๐ŸŸข Recruiting Phase1 ๐Ÿ“‹ Clinical Research Protocol Sponsor: University Health Network, Toronto

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This is a phase I, dose escalating study evaluating the safety of combining talazoparib and low dose consolidative thoracic radiotherapy for small cell lung cancer patients. This study will also determine the maximum tolerated dose (MTD) of talazoparib in combination with low dose thoracic radiotherapy. Patients will start on talazoparib on day 1 of study intervention, and will continue to orally take talazoparib until the last day of radiation therapy. Up to 24 patients will be enrolled to the study, where the first 3 patients will start with a starting dose level of talazoparib is 0.5 mg PO once daily. This will increase to 1mg daily with each new cohort.
