A Study to Evaluate the Safety and Efficacy of Glofitamab in Combination With Rituximab (R) Plus Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (CHOP) in Circulating Tumor (ct)DNA High-Risk Patients With Untreated Diffuse Large B-Cell Lymphoma

Registration Number
NCT04980222
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This Phase II, open-label, multicenter study will evaluate the safety, efficacy, and pharmacokinetics of glofitamab in combination with rituximab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in individuals with circulating tumor DNA (ctDNA) high-risk diffuse large B-cell lymphoma (DLBCL), as the first line of treatment.

Exclusion Criteria
  • Current diagnosis of B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and classic Hodgkin lymphoma (gray-zone lymphoma), primary mediastinal (thymic) large B-cell lymphoma, T-cell/histiocyte-rich large B-cell lymphoma, Burkitt lymphoma, central nervous system (CNS) lymphoma (primary or secondary involvement), primary effusion DLBCL, and primary cutaneous DLBCL
  • Contraindication to any of the individual components of R-CHOP, including prior receipt of anthracyclines, history of severe allergic or anaphylactic reactions to murine monoclonal antibodies, or known sensitivity or allergy to murine products
  • Prior treatment for indolent lymphoma
  • Prior solid organ or allogeneic stem cell transplant
  • Prior therapy for DLBCL and high-grade B-cell lymphoma (HGBCL) with the exception of palliative, short-term treatment with corticosteroids
