Study Endpoints

Primary Endpoints

The frequency and severity of treatment-emergent adverse events (TEAEs) including treatment-emergent serious adverse events (TESAEs)
Up to 90 days after the last administration of study treatment
Maximum Tolerated Dose (MTD): Number of participants experiencing dose-limiting toxicities (DLTs) at each dose level in the dose escalation part of the study
From first dose of study treatment to the end of Cycle 1 (each cycle is 21 days)
Maximum Administered Dose (MAD): Number of participants experiencing dose-limiting toxicities (DLTs) at each dose level in the dose escalation part of the study
From first dose of study treatment to the end of Cycle 1 (each cycle is 21 days)
Maximum concentration (Cmax) of the respective dosing interval of BAY2965501 after single dose and multiple-dose
From pre-dose up to 24 hours after administration on Cycle 1 Day 1 (each cycle is 21 days)
Area under the curve [AUC (0 - 24)] of the respective dosing interval of BAY 2965501 after single-dose and multiple-dose
From pre-dose up to 24 hours after administration on Cycle 1 Day 1 (each cycle is 21 days)

If AUC(0-24) cannot be calculated reliably, it might become necessary to appoint the additional parameter AUC(0-tlast) as primary variable.

ArmTypeDescription
Dose escalation of BAY2965501EXPERIMENTALFor escalation part, different dose levels of BAY2965501 are planned.
Dose expansion of BAY2965501EXPERIMENTALFor expansion part, specific tumor types are recruited: NSCLC (non-small cell lung cancer).
Dose escalation of BAY2965501+pembrolizumabEXPERIMENTALFor escalation part different dose levels of BAY2965501 are planned in combination with 200mg pembrolizumab. BAY2965501 will be taken in combination with 200mg pembrolizumab every 3 weeks.
Dose expansion of BAY2965501 +pembrolizumabEXPERIMENTALFor expansion part, specific tumor types are recruited (non-small cell lung cancer (NSCLC) and gastric/gastroesophageal junction (GEJ) adenocarcinoma). BAY2965501 will be taken in combination with 200mg pembrolizumab every 3 weeks.
Dose escalation of BAY 2965501 + pembrolizumab + platinum-based regimenEXPERIMENTALThe starting dose of BAY 2965501 with pembrolizumab for this combination will be no higher than one dose level below that shown to be safe in BAY 2965501 and pembrolizumab dose escalation. The doses of platinum-based regimen will be as per standard of care and given for a maximum of 6 cycles, in line with the current labeled dose. The dose of pembrolizumab will be 200 mg every 3 weeks, in line with the current labeled dose.
Dose expansion of BAY 2965501 + pembrolizumab + platinum-based regimenEXPERIMENTALParticipants with selected (to be decided by the sponsor) advanced solid tumors will be recruited in a dose expansion cohort of BAY 2965501 with pembrolizumab and platinum-based regimen.
