Official title
A Single Arm Study With Safety Run-in of Peptide Receptor Radionuclide Therapy (PRRT) in Combination With Immunotherapy for Patients With Merkel Cell Cancer (HCRN MCC20-443; iPRRT Study)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to find out what effects an immunotherapy drug, called pembrolizumab, combined with a radioactive drug, called lutetium Lu 177 dotatate (Lutathera®) have on patients with Merkel cell carcinoma. Pembrolizumab works by helping patient's immune system to fight cancer. Lutathera works by killing cancer cells. Pembrolizumab is approved by the FDA to treat Merkel cell cancer and has caused some Merkel cell cancers to shrink and/or resolve. Lutathera is FDA-approved to treat some neuroendocrine tumors and has caused some patient's neuroendocrine tumors to shrink and allowed them to live longer, but it is not approved by the FDA to treat Merkel cell cancer. The combination of Lutathera and pembrolizumab to treat Merkel cell cancer is investigational, which means this combination is not approved by the FDA to treat Merkel cell cancer.
