Classical Hodgkin Lymphoma Recurrent research hub

A Study to Evaluate the Safety and Efficacy of Pembrolizumab (MK-3475) Coformulated With Berahyaluronidase Alfa (MK-3475A) in Participants With Relapsed or Refractory Classical Hodgkin Lymphoma (rrcHL) or Relapsed or Refractory Primary Mediastinal Large B-cell Lymphoma (rrPMBCL)(MK-3475A-F65)

This study looks at a new way to give an existing medicine, pembrolizumab, for certain types of lymphoma. Instead of an IV, it's given as an injection under the skin, combined with another substance to help it spread. We want to see how well it works and if it's safe.
