Prednisone/prednisolone

This study is researching an experimental drug called odronextamab, referred to as study drug. The study is focused on participants with previously untreated follicular lymphoma (a type of non-Hodgkin lymphoma or NHL). This study will be made up of two parts: Part 1 (non-randomized) and Part 2 (randomized - controlled). The aim of Part 1 of the study is to see how safe and tolerable the study drug is when given alone. The aim of Part 2 of the study is to see how the study drug works compared to rituximab (called the "comparator drug") and chemotherapy (the current standard of care for NHL). Standard of care means the usual medication expected and used when receiving treatment for a condition. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drug (which could make the study drug less effective or could lead to side effects) * How the study drug affects quality of life and ability to complete routine daily activities.

This study will test whether BNT324 is safe and works better against metastatic castration-resistant prostate cancer (mCRPC) than the current standard of care (SoC) chemotherapy, which is docetaxel (given together with the steroid medicines prednisone or prednisolone). The study will include participants with mCRPC that have been previously treated with androgen receptor pathway inhibitor, but with no previous taxane-based systematic chemotherapy for mCRPC. The main goals of this study are: * To find out if BNT324 helps participants live longer without their cancer getting worse (radiographic progression-free survival \[rPFS\]). * To find out if BNT324 helps participants live longer overall (overall survival \[OS\]).
