Carboplatin-paclitaxel-bevacizumab + ubamatamabEXPERIMENTALAll participants will receive 3 cycles of the combination carboplatin-paclitaxel-bevacizumab + ubamatamab. After the 3 cycles, they will undergo surgery if it is feasible. Subsequently, they will receive maintenance treatment: * ubamatamab + bevacizumab: for participants with BRCA wild-type and HRD negative tumors and for participants with a disease characterized by a BRCA mutation, or HRD positive status, and experiencing stable disease during the chemotherapy * Olaparib + bevacizumab (standard of care): for participants with a disease characterized by a BRCA mutation, or HRD-positive status, and experiencing complete or partial response during the chemotherapy.
