This is a Phase III, randomized, open-label, 3-arm, multicenter, international study
assessing the efficacy and safety of Dato-DXd with or without durvalumab compared with ICT in
participants with stage I to III TNBC with residual invasive disease in the breast and/or
axillary lymph nodes at surgical resection following neoadjuvant systemic therapy.

This phase III trial uses the Decipher risk score to guide therapy selection. Decipher score is based on the activity of 22 genes in prostate tumor and may predict how likely it is for recurrent prostate cancer to spread (metastasize) to other parts of the body. Decipher score in this study is used for patient selection and the two variations of treatment to be studied: intensification for higher Decipher score or de-intensification for low Decipher score. Patients with higher Decipher risk score will be assigned to the part of the study that compares the use of 6 months of the usual treatment (hormone therapy and radiation treatment) to the use of darolutamide plus the usual treatment (intensification). The purpose of this section of the study is to determine whether the additional drug can reduce the chance of cancer coming back and spreading in patients with higher Decipher score. The addition of darolutamide to the usual treatment may better control the cancer and prevent it from spreading. Alternatively, patients with low Decipher risk score will be assigned to the part of the study that compares the use of radiation treatment alone (de-intensification) to the usual approach (6 months of hormone therapy plus radiation). The purpose of this part of the study is to determine if radiation treatment alone is as effective compared to the usual treatment without affecting the chance of tumor coming back in patients with low Decipher score prostate cancer. Radiation therapy uses high energy to kill tumor cells and reduce the tumor size. Hormone therapy drugs such as darolutamide suppress or block the production or action of male hormones that play role in prostate cancer development. Effect of radiation treatment alone in patients with low Decipher score prostate cancer could be the same as the usual approach in stabilizing prostate cancer and preventing it from spreading, while avoiding the side effects associated with hormonal therapy.

This phase III trial compare the effects of adding definitive treatment (either radiation therapy or prostate removal surgery) to standard systemic therapy in treating patients with prostate cancer that has spread to other places in the body (advanced). Removing the prostate by either surgery or radiation therapy in addition to standard systemic therapy for prostate cancer may lower the chance of the cancer growing or spreading.

This phase III trial compares the effect of usual treatment (lenalidomide) to using daratumumab/rHuPH20 plus the usual treatment after stem cell transplantation in patients with multiple myeloma. This drug combination may help patients live longer after their stem cell transplant. Another purpose of this study is to learn if the presence and amount of minimal residual disease (MRD) can help doctors predict when a patients multiple myeloma will get worse. MRD is the name for the small number of cancer cells that remain in the patient even after their multiple myeloma has been treated and they have no symptoms of the disease. Drugs used in chemotherapy, such as lenalidomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with daratumumab/rHuPH20, may induce changes in bodys immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and daratumumab/rHuPH20 may work better in treating patients with multiple myeloma compared to lenalidomide alone.
