  • Firstline Pembrolizumab Alone or in Combination with Pemetrexed and Carboplatin in Induction / Maintenance or Postprogression in Treating Patients with Stage IV Non-squamous Non-small Cell Lung Cancer

    This phase III trial studies whether pembrolizumab alone as a first-line treatment, followed by pemetrexed and carboplatin with or without pembrolizumab after disease progression is superior to induction with pembrolizumab, pemetrexed and carboplatin followed by pembrolizumab and pemetrexed maintenance in treating patients with stage IV non-squamous non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as pemetrexed and carboplatin, 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. It is not yet known whether giving first-line pembrolizumab followed by pemetrexed and carboplatin with or without pembrolizumab works better in treating patients with non-squamous non-small cell cancer.

  • Targeted Treatment (Ramucirumab Plus Pembrolizumab) for Advanced Non-Small Cell Lung Cancer (A Lung-MAP Non-Matched Treatment Trial)

    This phase II Lung-MAP Non-Matched treatment trial studies how well ramucirumab and pembrolizumab work versus standard of care in treating patients with non-small cell lung cancer that is stage IV or has come back (recurrent). Ramucirumab is a monoclonal antibody that attaches to and inhibits a molecule called VEGFR-2. This may restrain new blood vessel formation therefore reducing nutrient supply to tumor which may interfere with tumor cell growth and expansion. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in standard of care chemotherapy for non-small cell lung cancer, such as docetaxel, gemcitabine hydrochloride, and pemetrexed, 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 ramucirumab and pembrolizumab together may work better in treating patients with non-small lung cancer compared to standard of care.

  • Pembrolizumab with or without Stereotactic Body Radiation Therapy in Treating Patients with Advanced or Metastatic Merkel Cell Cancer

    This randomized phase II trial studies how well pembrolizumab with or without stereotactic body radiation therapy works in treating patients with Merkel cell cancer that has spread to other places in the body. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving pembrolizumab with stereotactic body radiation therapy may work better in treating patients with Merkel cell cancer.

  • Maintenance Chemotherapy with or without Local Consolidative Therapy in Treating Patients with Stage IV Non-small Cell Lung Cancer

    This randomized phase II / III trial studies how well giving maintenance chemotherapy with or without local consolidation therapy works in treating patients with stage IV non-small cell lung cancer. Drugs used in maintenance chemotherapy, such as docetaxel, pemetrexed disodium, erlotinib hydrochloride, and gemcitabine 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. Local consolidation therapy such as radiation / stereotactic body radiation or surgery may kill cancer cells left after initial treatment. Giving maintenance chemotherapy and local consolidation therapy together may work better than maintenance chemotherapy alone in treating patients with stage IV non-small cell lung cancer.

  • A Study of Enfortumab Vedotin Alone or With Other Therapies for Treatment of Urothelial Cancer

    This study will test an experimental drug (enfortumab vedotin) alone and with different combinations of anticancer therapies. Pembrolizumab is an immune checkpoint inhibitor (CPI) that is used to treat patients with cancer of the urinary system (urothelial cancer). This type of cancer includes cancer of the bladder, renal pelvis, ureter or urethra. Some parts of the study will look at locally-advanced and metastatic urothelial cancer, which means the cancer has spread to nearby tissues or to other areas of the body. Other parts of the study will look at muscle-invasive urothelial cancer, which is cancer at an earlier stage that has spread into the muscle wall of the bladder. This study will look at the side effects of enfortumab vedotin alone and with other anticancer therapies. A side effect is a response to a drug that is not part of the treatment effect. This study will also test if the cancer shrinks with the different treatment combinations.
