This phase I/II trial studies the best dose and side effects of peposertib and to see how well it works with avelumab and hypofractionated radiation therapy in treating patients with solid tumors and hepatobiliary malignancies that have spread to other places in the body (advanced/metastatic). Peposertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the bodys immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving peposertib in combination with avelumab and hypofractionated radiation therapy may work better than other standard chemotherapy, hormonal, targeted, or immunotherapy medicines available in treating patients with solid tumors and hepatobiliary malignancies.

The purpose of this study is to evaluate the safety and tolerability of AB521 when taken
alone in participants with advanced solid tumor malignancies and clear cell renal cell
carcinoma (ccRCC).

Patients will be registered prior to, during or at the completion of neoadjuvant chemotherapy
(Paclitaxel 175 mg/m2 IV over 3 hours and Carboplatin AUC 6 IV on Day 1 every 21 days for 3-4
cycles). Registered patients who progress during neoadjuvant chemotherapy will not be
eligible for iCRS and will be removed from the study.

Following completion of neoadjuvant chemotherapy, interval cytoreductive surgery (iCRS) will
be performed in the usual fashion in both arms. Patients will be randomized at the time of
iCRS (iCRS must achieve no gross residual disease or no disease >1.0 cm in largest diameter)
to receive HIPEC or no HIPEC. Patients randomized to HIPEC (Arm A) will receive a single dose
of cisplatin (100mg/m2 IP over 90 minutes at 42 C) as HIPEC. After postoperative recovery
patients will receive standard post-operative platinum-based combination chemotherapy.
Patients randomized to surgery only (Arm B) will receive postoperative standard chemotherapy
after recovery from surgery.

Both groups will receive an additional 2-3 cycles of platinum-based combination chemotherapy
per institutional standard (Paclitaxel 175 mg/m2 IV over 3 hours and Carboplatin AUC 6 IV on
Day 1 every 21 days for 2-3 cycles) for a maximum total of 6 cycles of chemotherapy
(neoadjuvant plus post-operative cycles) followed by niraparib individualized dosing until
progression or 36 months (if no evidence of disease).

The primary objective of this phase IIb/III study is to evaluate whether the combination of
lurbinectedin plus doxorubicin given as first line treatment for metastatic leiomyosarcoma
(LMS) prolongs the progression-free survival (PFS) by Independent Review Committee (IRC) when
compared to doxorubicin administered as a single agent.

This phase II ComboMATCH treatment trial compares the effect of neratinib to the combination of neratinib and palbociclib in treating patients with HER2 positive solid tumors. Neratinib and palbociclib are in a class of medications called kinase inhibitors. They work by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of tumor cells. Giving neratinib and palbociclib in combination may shrink or stabilize cancers that over-express a specific biomarker called HER2.

This phase II trial tests how well nivolumab in combination with chemotherapy drugs along with radiation therapy works in treating patients with nasopharyngeal cancer. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as gemcitabine and cisplatin, 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. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Researchers want to find out what effects, good and/or bad, adding nivolumab to chemotherapy has on patients with newly diagnosed NPC. In addition, they want to find out if children with NPC may be treated with less radiation therapy and whether this decreases the side effects of therapy.

This phase II trial tests how well giving durvalumab with standard chemotherapy, gemcitabine and cisplatin, before surgery works in treating patients with high risk liver cancer (cholangiocarcinoma) that can be removed by surgery (resectable). Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as gemcitabine and cisplatin, 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. Giving durvalumab with gemcitabine and cisplatin before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed in patients with high risk resectable cholangiocarcinoma.

Phase 1 study comprised of open-label, dose escalation and expansion cohort study of
P-CD19CD20-ALLO1 allogeneic T stem cell memory (Tscm) CAR-T cells in subjects with
relapsed/refractory B cell malignancies

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.
