First global approval for glofitamab (COLUMVI®)

March 31, 2023 by Janice Reichert

Hoffmann-La Roche Limited (Roche Canada) announced that on March 24, 2023 Health Canada authorized COLUMVI® (glofitamab for injection) for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified, DLBCL arising from follicular lymphoma (trFL), or primary mediastinal B-cell lymphoma (PMBCL), who have received two or more lines of systemic therapy and are ineligible to receive or cannot receive CAR-T cell therapy or have previously received CAR-T cell therapy. COLUMVI has been issued marketing authorization with conditions, pending the results of trials to verify its clinical benefit. The authorization of COLUMVI® is the first in Canada and globally.

Glofitamab (RO7082859) is a full-length IgG1λ/ҡ bispecific T cell redirecting antibody targeting CD20 on malignant B cells and CD3 on T cells. This bispecific antibody was developed by Roche using the 2:1 CrossMab technology, characterized by 3 antigen-binding fragment (Fab) arms enabling monovalent binding to CD3ɛ and bivalent binding to CD20, with the second CD20 arm fused to the CD3ɛ-binding arms via a flexible linker. Glofitamab also features a heterodimeric Fc region engineered with PG LALA mutations to abolish binding to FcɣRs and C1q.

The Health Canada authorization is based on data from the open-label, phase I/II, multicenter, multi-cohort trial (NP30179) conducted to evaluate COLUMVI as monotherapy in patients with relapsed or refractory B-cell lymphoma. In the single-arm DLBCL cohort (n=108), 84.3% of patients were refractory to their most recent therapy and about one-third (34.3%) had received prior CAR T-cell therapy. The primary efficacy outcome measure was complete response (CR) rate as assessed by the IRC using 2014 Lugano response criteria. Results showed that 35.2% of patients (n=38/108) achieved a complete response (CR; a disappearance of all signs of cancer), and 50.0% (n=54/108) achieved an objective response (OR; the combination of CR or partial response, a decrease in the amount of cancer in their body).

An marketing authorization application containing data from the Phase 1/2 NP30179 study (NCT03075696) evaluating glofitamab for NHL was submitted to the European Medicines Agency. A biologics license application for glofitamab undergoing review by the Food and Drug Administration has a first action date of July 1, 2023.
