NCT03304639

Testing the Addition of Radiation Therapy to Immunotherapy for Merkel Cell Carcinoma

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 (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. 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.

Testing the Combination of Two Anticancer Drugs M1774 (Tuvusertib) and Avelumab to Evaluate Their Safety and Effectiveness in Treating Merkel Cell Skin Cancer, MATRiX Trial

This phase II trial compares tuvusertib in combination with avelumab to tuvusertib alone to determine whether the combination therapy will lengthen the time before the cancer starts getting worse in patients with Merkel cell cancer that has not responded to previous treatment (refractory). Tuvusertib is a drug that inhibits an enzyme called ataxia telangiectasia and Rad3 related (ATR) kinase, which is an enzyme that plays a role in repair of damaged deoxyribonucleic acid (DNA) as well as tumor cell replication and survival. It may lead to tumor cell death by inhibiting ATR kinase activity. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving tuvusertib in combination with avelumab may lengthen the time before Merkel cell cancer starts getting worse compared to giving avelumab alone.

Immunotherapy in Combination With Prednisone and Sirolimus for Kidney Transplant Recipients With Unresectable or Metastatic Skin Cancer

This phase II trial tests the combination of nivolumab and ipilimumab with sirolimus and prednisone for the treatment of skin (cutaneous) cancer that cannot be removed by surgery (unresectable) or that has spread from where it first started to other places in the body (metastatic) in kidney transplant recipients. Immunotherapy with nivolumab and ipilimumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Sirolimus and prednisone are immunosuppressants that are given to keep the body from rejecting the transplanted kidney. Giving nivolumab and ipilimumab in combination with sirolimus and prednisone may kill more cancer cells, while also keeping the transplanted kidney healthy, in patients with unresectable or metastatic cutaneous cancer who have received a kidney transplant.

Targeted Therapy and Avelumab in Merkel Cell Carcinoma

10.17 GoTHAM is intended as a signal-seeking, biomarker, phase Ib/II study that will evaluate the safety and anti-tumour activities of the novel combination of avelumab with 177-Lu-DOTATATE (a type of peptide receptor radionuclide therapy; PRRT) or external beam radiation therapy (EBRT) in patients with metastatic Merkel cell carcinoma (mMCC).

Personalized Neoantigen Peptide-Based Vaccine in Combination With Pembrolizumab for Treatment of Advanced Solid Tumors

This phase I/II trial tests the safety and tolerability of an experimental personalized vaccine when given by itself and with pembrolizumab in treating patients with solid tumor cancers that have spread to other places in the body (advanced). The experimental vaccine is designed target certain proteins (neoantigens) on individuals' tumor cells. 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 the personalized neoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors.

Tacrolimus, Nivolumab, and Ipilimumab in Treating Kidney Transplant Recipients With Selected Unresectable or Metastatic Cancers

This phase I trial studies how well tacrolimus, nivolumab, and ipilimumab work in treating kidney transplant recipients with cancer that cannot be removed by surgery (unresectable) or has spread to other places in the body (metastatic). Tacrolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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 tacrolimus, nivolumab, and ipilimumab may work better in treating kidney transplant recipients with cancer compared to chemotherapy, surgery, radiation therapy, or targeted therapies.
