To determine the maximum tolerated dose(s) (MTD) or the Recommended Dose for Expansion (RDE) and dosing regimen for further development of BI 764532. The MTDs will be defined based on the frequency of patients experiencing dose limiting toxicities (DLTs) during the MTD evaluation period in studied regimens. The RDE will be guided by overall safety, efficacy, Pharmacokinetics (PK) and Pharmacodynamics (PD) assessments.
Additional objectives are to document the safety and tolerability of BI 764532, to characterise pharmacokinetics and pharmacodynamics, and to evaluate efficacy signals.
Phase Ib will further explore BI 764532 in selected patients populations based on data from phase Ia.
The Phase Ib objectives, endpoints and design will be specified in a study protocol amendment after availability of phase Ia results.

BI 764532 |
- Maximum tolerated dose (MTD) [ Time Frame: up to 36 months ]Maximum tolerated dose (MTD) in any studied regimen defined as the highest dose with less than 25% risk of the true Dose Limiting Toxicity (DLT) rate being equal or above 33% during the MTD evaluation period. Separate MTDs will be determined for each Regimen.
- Number of patients with DLTs in the MTD evaluation period [ Time Frame: up to 36 months ]
- Cmax: maximum measured concentration of BI 764532 [ Time Frame: up to 36 months ]
- AUCτ: area under the concentration-time curve of the analyte over a uniform dosing interval τ [ Time Frame: up to 36 months ]
- Objective response based on RECIST 1.1 criteria in patients with measurable disease [ Time Frame: up to 36 months ]Objective response based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria in patients with measurable disease
