This study will evaluate the safety, efficacy, optimal dose, and pharmacokinetics (PK) of BNT326 as monotherapy (Part 1) and as combination treatment with immunotherapeutic agents (Part 2) in participants with histologically or cytologically confirmed solid tumors that are advanced (i.e., either metastatic or recurrent tumors with no further definitive treatment possible) and/or have relapsed/progressed after prior therapy.
Aged ≥18 years at the time of giving informed consent. Local laws will be followed if the age of consent is older.
Have histologic or cytologic documented advanced disease, either at relapse or upon diagnosis of metastatic disease. This requirement may be considered met when advanced disease derives from unequivocal progression of a previously biopsied site of disease (e.g., progression of residual tumor after concomitant chemo-radiation for Stage III NSCLC).
Have measurable disease defined by RECIST v1.1.
All participants must provide a tumor tissue sample (Formalin-fixed paraffin-embedded [FFPE] slides) from archival tissue. The archival tissue can be an FFPE block or freshly cut slides derived from the advanced setting or a new/fresh tumor biopsy.
Have a history of intolerance to treatment with a topoisomerase I inhibitor or intolerance to an ADC that consists of a topoisomerase I inhibitor, including but not limited to topotecan, irinotecan, and deruxtecan (e.g., severe diarrhea).
