This phase II trial investigates the effect of avelumab or hydroxychloroquine sulfate with or without palbociclib in treating patients with stage II-III breast cancer that is positive for disseminated tumor cells (DTCs) after curative therapy. DTCs are breast cancer cells that are asleep (dormant) in the bone marrow. There are multiple ways in which these cells stay alive, and three of these mechanisms are inhibited by the drugs in this trial. First, dormant cancer cells need a protein signal pathway involving CDK 4/6 to start dividing once they wake up in order to survive as an active cancer cell. Palbociclib works by blocking the CDK 4/6 protein and by doing so may limit the dormant cancer cell from being able to survive. In addition, palbociclib may also help both of the other drugs in the trial to work better. Second, dormant cancer cells also use a process called autophagy to generate their own nutrition, which can allow them to stay asleep. Hydroxychloroquine has been shown to block autophagy, which leads to starvation of the cells. Third, dormant cancer cells are able to hide from the bodys immune system. The immune system sends a type of cell called T cells throughout the body to detect and fight infections and diseasesincluding cancers. One way the immune system controls the activity of T cells is through the PD-1/PD-L1 (programmed cell death protein-1) pathway. However, some cancer cells hide from T-cell attack by taking control of the PD-1/PD-L1 interaction and this stops T cells from attacking cancer cells. Avelumab is an antibody designed to block the PD-1/PD-L1 pathway and helps the immune system in detecting and fighting dormant cancer cells. Because palbociclib, hydroxychloroquine, and avelumab work on the mechanisms that keep the dormant cells alive, taking one or a combination of these drugs may be able to eliminate DTCs.

This phase II trial tests whether nivolumab and ipilimumab works to shrink tumors in patients with liver cancer that has spread to nearby tissue or lymph nodes (locally advanced), has spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Nivolumab and ipilimumab may be effective in killing tumor cells in patients with liver cancer.

The purpose of this study is to assess the efficacy and safety of co-formulated
pembrolizumab/quavonlimab versus other treatments in participants with MSI-H or dMMR
Metastatic Stage IV Colorectal Cancer.

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 II trial tests whether loncastuximab tesirine works to shrink tumors in patients with marginal zone lymphoma (MZL), a type of immune cell cancer, that has come back (relapsed) or become unresponsive to one or more treatments (refractory). Loncastuximab tesirine is composed of an antibody, called loncastuximab linked to a chemotherapy drug called tesirine. Loncastuximab attaches to specific proteins in the cancer cell and delivers tesirine only to the cancer cells because of this antibody. Ultimately this results in cancer cell death only without exposing normal cells to the tesirine.

The goal of this trial is to see if active surveillance monitoring and hormonal therapy in
patients diagnosed with ductal cell carcinoma in situ (DCIS), an early stage of breast
cancer, can be an effective management of the disease.

Participants will be asked to receive control hormonal therapy or an investigational hormonal
therapy treatment. Participants will be asked to return for evaluation with MRI at three
months and six months. Depending on the evaluation participants will have the option to
continue on the treatment. If the evaluation suggests surgery is recommended, the participant
will discontinue the study treatment and will undergo surgery. In addition to the treatment
and MRI evaluation, participants will be asked to provide blood sample to understand their
immune status, provide saliva sample for genetic testing, provide the study with a portion of
the tissue or slides generated from tissue removed during surgery performed as part of their
standard of care.
