ATR Inhibitor BAY 1895344 Plus Niraparib Phase 1b Study in Advanced Solid Tumors and Ovarian Cancer
Study Details
Study Description
Brief Summary
The purpose of the study is to test how well patients with advanced solid tumors and ovarian cancer respond to treatment with BAY1895344 in combination with niraparib. In addition researchers want to find for patients the optimal dose of BAY1895344 in combination with niraparib, how the drug is tolerated and the way the body absorbs, distributes and discharges the drug. The study medication BAY1895344 works by blocking a substance produced by the body (ATR Kinase) which is important for the growth of tumor cells. Niraparib works by blocking a substance produced by the body (PARP enzymes) in a way that tumor cells can be killed, or made more susceptible to chemotherapy.

Outcome Measures
Primary Outcome Measures
- Maximum tolerated dose (MTD) and / or recommended Phase II dose (RP2D) of BAY1895344 [Up to 28 days after last administration of study Intervention]
The MTD is defined as the highest dose level that can be given so that the toxicity probability is closest to the target toxicity PT=30% or as the maximum tested dose, whichever is achieved first during Cycle 1. Estimation of the MTD will be based on the estimation of the observed dose-dependent incidence rate of DLT in Cycle 1.
- Incidence of treatment emergent adverse events (TEAEs) [Up to 28 days after the last administration of study intervention]
- Severity of treatment emergent adverse events (TEAEs) [Up to 28 days after the last administration of study intervention]
- Incidence of treatment emergent serious adverse events (TESAEs) [Up to 28 days after the last administration of study intervention]
- Severity of treatment emergent serious adverse events (TESAEs) [Up to 28 days after the last administration of study intervention]
- Frequency of Dose Limiting Toxicities at each dose level during the DLT observation period for Cycle 1 [28 days after first administration of study intervention (Cycle 1)]
Maximum tolerated dose (MTD)
Secondary Outcome Measures
- Incidence of participants with complete response (CR) [Up to 24 months]
- Incidence of participants with partial response (PR) [Up to 24 months]
- Incidence of participants with stable disease (SD) [Up to 24 months]
- Incidence of participants with progressive disease (PD) [Up to 24 months]
- Objective response rate (ORR) [Up to 24 months]
- Disease control rate (DCR) [Up to 24 months]
- Cmax (Maximal plasma exposure) of BAY1895344 after single dose administration [Pre-dose, 0.5 hour, 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours post-dose on Cycle 1, Day 1]
- AUC(0-12) of BAY1895344 after single dose administration [Pre-dose, 0.5 hour, 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours post-dose on Cycle 1, Day 1]
- Cmax,md of BAY1895344 after multiple dose administration [Pre-dose, 0.5 hour, 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours post-dose on Cycle 1, Day 17]
- AUC(0-12)md of BAY1895344 after multiple dose administration [Pre-dose, 0.5 hour, 1 hour, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours post-dose on Cycle 1, Day 17]
