Raludotatug Deruxtecan

Researchers are looking for new ways to treat metastatic nonsquamous non-small cell lung cancer (NSCLC) that has been treated before. Metastatic means the cancer has spread to other parts of the body. Nonsquamous means the cancer did not start in squamous cells, which are flat cells that line the inside of the lungs. Standard treatment (usual treatment) for NSCLC is surgery, then immunotherapy with or without chemotherapy after surgery. Immunotherapy is a treatment that helps the immune system fight cancer. Chemotherapy is a medicine that works to destroy cancer cells or stop them from growing. However, standard treatment may not work or may stop working for some people. Researchers want to know if 2 antibody drug conjugates (ADCs) can help treat metastatic nonsquamous NSCLC that did not respond (get smaller or go away) to treatment. An ADC attaches to specific targets on cancers cells and delivers treatment to destroy those cells. Researchers will compare 2 different ADCs (the study treatments) to chemotherapy in this study. The goals of this study are to learn: * About the safety of the study treatments and if people tolerate them * How many people have the cancer respond to the study treatments

Researchers are looking for other ways to treat relapsed high-grade serous ovarian cancer. Relapsed means the cancer came back after treatment. High-grade means the cancer cells grow and spread quickly. Serous means the cancer started in the cells that cover the ovaries, the lining of the belly, or in the fallopian tubes. Standard treatment (usual treatment) for people with relapsed high-grade serous ovarian cancer may include: * Chemotherapy, which is a treatment that uses medicine to destroy cancer cells or stop them from growing * Targeted therapy, which is a treatment that works to control how specific types of cancer cells grow and spread Raludotatug deruxtecan (R-DXd) is a study treatment that is an antibody drug conjugate (ADC). An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. Researchers want to know if R-DXd is safe to take with other treatments and if people tolerate them together. They also want to learn how many people have the cancer respond (gets smaller or goes away) to the treatments.
