A Precision Medicine Approach (SMMART-ACT) for the Treatment of Patients With Advanced Sarcoma, Prostate, Breast, Ovarian or Pancreatic Cancer
Recruiting
This phase II trial tests the how well a precision medicine approach (serial measurements of molecular and architectural response to therapy \[SMMART\])-adaptive clinical treatment \[ACT\]) works in treating patients with sarcoma, prostate, breast, ovarian or pancreatic cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced).

Comparing Radiation Therapy to Usual Care for Patients With High-Risk Bone Asymptomatic Metastases
Recruiting
This phase III trial compares the effect of adding radiation therapy to usual care on the occurrence of bone-related complications in cancer patients with high-risk bone metastases that are not causing symptoms (asymptomatic). High-risk bone metastases are defined by their location (including hip, shoulder, long bones, and certain levels of the spine), or size (2 cm or larger). These bone metastases appear to be at higher risk of complications such as fracture, spinal cord compression, and/or pa... Read More

Testing the Addition of Immunotherapy Before Surgery for Patients With Sarcomatoid Mesothelioma
Recruiting
This phase II trial evaluates the safety and effectiveness of giving immunotherapy (nivolumab and ipilimumab) before surgery for controlling disease in patients with stage I-IIIa sarcomatoid mesothelioma. 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. Giving immunotherapy before surgery may be more effective at controlling disease in patients wit... Read More
