  • Testing the Addition of a Type of Drug Called Immunotherapy to the Usual Chemotherapy Treatment for Non-small Cell Lung Cancer, ALCHEMIST Chemo-IO Study

    This phase III ALCHEMIST trial compares the addition of pembrolizumab to usual chemotherapy versus usual chemotherapy for the treatment of stage IB, II, or IIIA non-small cell lung cancer that has been removed by surgery. 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 cisplatin, pemetrexed, carboplatin, gemcitabine hydrochloride, and paclitaxel, 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. The purpose of this trial is to find out if the addition of pembrolizumab to usual chemotherapy is better or worse than usual chemotherapy alone for non-small cell lung cancer.

  • Testing the Timing of Pembrolizumab Alone or With Chemotherapy as First Line Treatment and Maintenance in 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.

  • Testing the Addition of Pembrolizumab, an Immunotherapy Cancer Drug to Olaparib Alone as Therapy for Patients with Pancreatic Cancer That Has Spread with Inherited BRCA Mutations

    This phase II trial studies whether adding pembrolizumab to olaparib (standard of care) works better than olaparib alone in treating patients with pancreatic cancer with germline BRCA1 or BRCA2 mutations that has spread to other places in the body (metastatic). BRCA1 and BRCA2 are human genes that produce tumor suppressor proteins. These proteins help repair damaged deoxyribonucleic acid (DNA) and, therefore, play a role in ensuring the stability of each cell’s genetic material. When either of these genes is mutated, or altered, such that its protein product is not made or does not function correctly, DNA damage may not be repaired properly. As a result, cells are more likely to develop additional genetic alterations that can lead to some types of cancer, including pancreatic 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. Olaparib is an inhibitor of PARP, a protein that helps repair damaged DNA. Blocking PARP may help keep tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. The addition of pembrolizumab to the usual treatment of olaparib may help to shrink tumors in patients with metastatic pancreatic cancer with BRCA1 or BRCA2 mutations.

  • Testing the Addition of an Anti-cancer Drug, Pembrolizumab, to the Usual Intravesical Chemotherapy Treatment (Gemcitabine) for the Treatment of BCG-Unresponsive Non-muscle Invasive Bladder Cancer

    This phase II trial studies the effect of adding pembrolizumab to gemcitabine in treating patients with non-muscle invasive bladder cancer whose cancer does not respond to Bacillus Calmette-Guerin (BCG) treatment. Chemotherapy drugs, such as 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. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the patient’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Adding pembrolizumab to gemcitabine may delay the return of BCG-unresponsive bladder cancer for longer period compared to gemcitabine alone.

  • Testing the Effects of MK-3475 (Pembrolizumab) with or without the Usual Chemotherapy Treatment for Patients 70 Years of Age and Older with Advanced Non-small Cell Lung Cancer

    This trial studies the side effects of pembrolizumab with or without chemotherapy in treating patients with stage IV non-small cell lung cancer that has come back (recurrent) and has spread to other places in the body (advanced). 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. Giving pembrolizumab with or without chemotherapy may shrink the tumor in older patients with non-small cell lung cancer.

  • Trying to Find the Correct Length of Treatment with Immune Checkpoint Therapy in Locally Advanced or Metastatic Urothelial Carcinoma

    This phase III trial compares survival in urothelial cancer patients who stop immune checkpoint inhibitor treatment after being treated for about a year to those patients who continue treatment with immune checkpoint inhibitors. Immunotherapy with monoclonal antibodies, such as avelumab, durvalumab, pembrolizumab, atezolizumab, and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Stopping the treatment with immune checkpoint inhibitors early in patients who have been responding to such therapy for approximately 1 year, may not change the benefit of treatment. This is because their immune system may continue to attack the tumor cells even if the treatment has stopped. A possible reason may be that the immune system has memory and remembers what it sees, including the cancer cells that it attacks. Stopping treatment with checkpoint inhibitors early may result in similar survival rate as if the treatment had not stopped and may also lead to fewer treatment-related side effects, an improvement in mental health, and a lower cost burden to patients.

  • Comparing Standard Treatment Alone to Radiation Therapy with or without Surgery with Standard Treatment for Patients with Limited Metastatic 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 pemetrexd 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. Immunotherapy with monoclonal antibodies, such as pembrolizumab, nivolumab, atezolizumab 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. 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.

  • Testing Pembrolizumab with Existing Cancer Therapy in Patients with Evidence of Residual Chronic Myelogenous Leukemia

    This phase II trial studies how well pembrolizumab and dasatinib, imatinib mesylate, nilotinib, or bosutinib work in treating patients with chronic myeloid leukemia and persistent detection of minimal residual disease, defined as the levels of a gene product called bcr-abl in the blood. 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. Dasatinib, imatinib mesylate, nilotinib, and bosutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and dasatinib, imatinib mesylate, nilotinib, or bosutinib may work better in treating patients with chronic myeloid leukemia compared to dasatinib, imatinib mesylate, nilotinib, or bosutinib alone.

  • Comparing the Outcome of Immunotherapy-Based Drug Combination Therapy with or without Surgery to Remove the Kidney in Metastatic Kidney Cancer, the PROBE Trial

    This phase III trial compares standard systemic treatment alone versus standard systemic treatment plus surgery to remove all or part of the affected kidney (cytoreductive nephrectomy) in treating patients with kidney cancer that has spread to other places in the body (metastatic). Standard systemic therapy for this type of cancer is immunotherapy-based combination therapy which may shrink the tumor and stimulate the immune system to attack the cancer. Systemic therapy is a type of treatment when drugs travel through the blood to cells all over the body. Immunotherapy with monoclonal antibodies, such as nivolumab, ipilimumab, pembrolizumab, and avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cytoreductive nephrectomy is a surgical procedure to remove as many cancer cells from the kidney as possible. This study will help determine whether addition of surgery to standard of care systemic therapy is better than systemic therapy alone for the treatment of metastatic kidney cancer.

  • Testing What Happens When an Immunotherapy Drug (Pembrolizumab) is Added to Radiation or Given by Itself Compared to the Usual Treatment of Chemotherapy with Radiation after Surgery for Recurrent Head and Neck Squamous Cell Carcinoma

    This phase II trial studies the effect of pembrolizumab in combination with radiation therapy or pembrolizumab alone compared to the usual approach (chemotherapy plus radiation therapy) after surgery in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or patients with a second head and neck cancer that is not from metastasis (primary). Radiation therapy uses high energy radiation or protons to kill tumor cells and shrink tumors. Chemotherapy drugs, such as cisplatin and carboplatin kill tumor cells by stopping them from dividing. 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. Giving pembrolizumab in combination with radiation therapy or pembrolizumab alone after surgery may work better than the usual approach in shrinking recurrent or primary head and neck squamous cell carcinoma.

  • 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 bladder cancer (MIBC), 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.
