This phase II trial tests whether using genetic testing of tumor tissue to select the optimal treatment regimen works in treating patients with clear cell renal cell (kidney) cancer that has spread to other places in the body (advanced or metastatic). The current Food and Drug Administration (FDA)-approved regimens for advanced kidney cancer fall into two categories. One treatment combination includes two immunotherapy drugs (nivolumab plus ipilimumab), which are delivered by separate intravenous infusions into a vein. The other combination is one immunotherapy drug (nivolumab infusion) plus an oral pill taken by mouth (cabozantinib). Nivolumab and ipilimumab are immunotherapies which release the brakes of the immune system, thus allowing the patient's own immune system to better kill cancer cells. Cabozantinib is a targeted therapy specifically designed to block certain biological mechanisms needed for growth of cancer cells. In kidney cancer, cabozantinib blocks a tumors blood supply. The genetic (DNA) makeup of the tumor may affect how well it responds to therapy. Testing the makeup (genes) of the tumor, may help match a treatment (from one of the above two treatment options) to the specific cancer and increase the chance that the disease will respond to treatment. The purpose of this study is to learn if genetic testing of tumor tissue may help doctors select the optimal treatment regimen to which advanced kidney cancer is more likely to respond.

This phase III trial compares the combination of four drugs (daratumumab-hyaluronidase, bortezomib, lenalidomide and dexamethasone) to the use of a three-drug combination (daratumumab-hyaluronidase, lenalidomide and dexamethasone) in patients with newly diagnosed multiple myeloma. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Daratumumab-hyaluronidase is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Anti-inflammatory drugs, such as dexamethasone lower the bodys immune response and are used with other drugs in the treatment of some types of cancer. Adding bortezomib to daratumumab-hyaluronidase, lenalidomide, and dexamethasone may be more effective in shrinking the cancer or preventing it from returning, compared to continuing on a combination of daratumumab-hyaluronidase, lenalidomide, and dexamethasone in patients with newly diagnosed multiple myeloma.

This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Radioactive drugs, such as lutetium Lu 177 dotatate, may carry radiation directly to tumor cells and may reduce harm to normal cells. Lutetium Lu 177 dotatate may be more effective than everolimus in shrinking or stabilizing advanced bronchial neuroendocrine tumors.

Rhabdomyosarcoma is a type of cancer that occurs in the soft tissues in the body. This phase III trial aims to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma. Another aim of the study it to find out how well patients with low risk rhabdomyosarcoma (LR-RMS) respond to standard chemotherapy when patients with VLR-RMS and patients who have rhabdomyosarcoma with DNA mutations get separate treatment. Finally, this study examines the effect of therapy intensification in patients who have RMS cancer with DNA mutations to see if their outcomes can be improved.

Multiple myeloma (MM) is a plasma cell disease characterized by the growth of clonal plasma
cells in the bone marrow. The purpose of this study is to assess the safety and toxicity of
ABBV-453 in adult participants with relapsed/refractory (R/R) MM. Adverse events and change
in disease activity will be assessed.

ABBV-453 is an investigational drug being developed for the treatment of R/R MM. Part 1 will
be a monotherapy dose escalation phase to determine the best dose of ABBV-453. In Part 2,
participants are placed in 1 of 3 groups called treatment arms. Each group receives a
different treatment. Approximately 28 to 48 adult participants in Part 1 and 150 to 312 adult
participants in Part 2 with R/R MM will be enrolled in the study in approximately 70 sites
worldwide.

In Part 1 and the Japan Cohort, Participants will receive oral ABBV-453 tablets once daily
(QD) in 28-day cycles. In Part 2, Arm 1, participants will receive continuous doses of oral
ABBV-453 tablets QD in combination with oral dexamethasone tablets once weekly in 28-day
cycles. In Part 2, Arm 2, participants will receive continuous doses of oral ABBV-453 tablets
QD in combination with subcutaneous injections of daratumumab every 1 to 4 weeks and oral
dexamethasone tablets once weekly in, 28-day cycles. In Part 2, Arm 3, participants will
receive continuous doses of oral ABBV-453 tablets QD in combination with subcutaneous
injections of daratumumab every 1 to 4 weeks, oral lenalidomide capsules QD on Days 1-21, and
oral dexamethasone tablets once weekly, in 28-day cycles.

There may be higher treatment burden for participants in this trial compared to their
standard of care. Participants will attend regular visits during the study at an approved
institution (hospital or clinic). The effect of the treatment will be frequently checked by
medical assessments, blood tests, and side effects.

This phase II trial studies the effects of niraparib in combination with dostarlimab prior to surgery in treating BRCA-mutated or PALB2-mutated stage I-III breast cancer. Niraparib is a PARP inhibitor, which means that it blocks an enzyme (proteins that help chemical reactions in the body occur) in cells called PARP. PARP helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Dostarlimab stimulates the immune system by blocking the PD-1 pathway. The PD-1 pathway controls the bodys natural immune response, but for some types of cancer, the immune system does not work as it should and is prevented from attacking tumors. Dostarlimab works by blocking the PD-1 pathway, which may help your immune system identify and catch tumor cells. Giving niraparib in combination with dostarlimab may work better against the tumor and maximize tumor shrinkage before surgery.
