Details and patient eligibility


To assess the safety and efficacy of two forms of Talazoparib therapy (injections subcutaneously Talazoparib and oral form for the treatment in the equivalent therapeutics dose

Full description

The intent of this study was to assess the safety and efficacy of two forms of Talazoparib therapy for the treatment of advanced solid tumors . After an enrollment period, patients will randomized to receive oral Talazoparib (1 mg, one times a day ) or subcutaneously Talazoparib (1 mg by subcutaneous injection with NovoPen / Autopen) one times a day in the appropriate volume
