Antitumor activity of temozolomide (30 mg/kg for 5 days), talazoparib (0.25 mg/kg twice daily for 5 days), or in combination against xenograft models sensitive to temozolomide (GBM2, Rh28, MGMT-deficient), or single-agent talazoparib (KT-10), and two additional alveolar rhabdomyosarcoma xenografts (Rh30, Rh41). Combination A (temozolomide 30 mg/kg for 5 days; talazoparib 0.1 mg/kg twice daily for 5 days); combination B (temozolomide 12 mg/kg for 5 days; talazoparib 0.25 mg/kg twice daily for 5 days).
