MT2022-60: Ph 2 Study of Pembro+ BEAM With ASCT for Relapsed Hodgkin Lymphoma

MT2022-60: A Phase II Study of Pembrolizumab+ BEAM Conditioning Regimen Before Autologous Stem Cell Transplant (ASCT) Followed by Pembrolizumab Maintenance in Patients of Relapsed or Refractory Classic Hodgkin Lymphoma

This is a Phase 2 single arm study to evaluate efficacy and safety of Pembrolizumab before with BEAM ASCT followed by Pembrolizumab maintenance for 1 year. Patients will receive 200 mg Pembrolizumab Q3week starting at day - 28 before stem cell transplant until 1 year after autologous stem cell transplant.
