Study Endpoints

Primary Endpoints

Objective Response Rate (ORR) per RECIST 1.1 as assessed by BICR
From start of study intervention until the first documented progression, or death from any cause, or end of study (up to approximately 3 years), whichever comes first

ORR is defined as the proportion of participants with a best overall response of confirmed complete response (CR) or partial response (PR) per RECIST 1.1 by BICR. CR is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have decreased in size to have a short axis of \<10 mm. PR is defined as a ≥30% decrease in the sum of diameters of target lesions taking as reference the baseline sum of diameters. RECIST 1.1 = Response Evaluation Criteria in Solid Tumors, version 1.1; BICR = blinded independent central review (BICR)

Treatment Arms

ArmTypeDescription
BAY2927088EXPERIMENTALAdult participants with metastatic or unresectable solid tumors with HER-2 activating mutations including: colorectal, biliary tract, bladder, cervical, endometrial, breast, and other solid tumor types. Participants will receive BAY2927088 20 mg BID until disease progression per RECICST 1.1, unacceptable toxicity, or until any other withdrawal criteria. RECIST 1.1 = Response Evaluation Criteria in Solid Tumors, version 1.1; BID: twice a day
Healthy participants from United StatesEXPERIMENTALThe healthy volunteers will be confined to the clinic throughout the intervention period of the study. The study includes visits during screening, intervention, and follow-up.
BAY2927088 + Itraconazole (ITZ)EXPERIMENTALParticipant will receive single dose BAY2927088 on Days 1 and 8, will receive itraconazole daily from Day 5 to Day 11.
BAY2927088 + Carbamazepine (CBZ)EXPERIMENTALParticipant will receive BAY2927088 single dose on Days 1 and 14, will receive carbamazepine daily from Day 3 to Day 15.
Intervention A - Intervention B - Intervention CEXPERIMENTALIntervention A: BAY2927088 is administered under fasted status. Intervention B: BAY2927088 is administered under fed status (light low-fat meal). Intervention C: BAY2927088 is administered under fed status (high fat, high calorie meal). Each participant will subsequently undergo a fourth intervention period that includes dosing with BAY2927088 and esomeprazole.
