A Clinical Study to Test if an Investigational Treatment Called BNT326 is Safe and Potentially Beneficial When Used Alone or in Combination With Other Investigational Treatments Such as BNT327, for People With Advanced Malignant Tumors
Trial Parameters
Brief Summary
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.
Eligibility Criteria
Key Inclusion Criteria (applicable to all participants and all parts unless otherwise specified): * 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 ECOG performance status of 0 or 1. * Have adequate organ and bone marrow function (as specified in the protocol) within 7 da
