Biogen Reaches Agreement with Genentech to Receive Royalties on the Potential Commercialization of a Late-Stage Bispecific Antibody as Part of Anti-CD20 Collaboration

• Glofitamab is an investigational T-cell engaging bispecific antibody targeting CD20 and CD3 in development for B-cell non-Hodgkin’s lymphoma and other blood cancers

CAMBRIDGE, Mass., Dec. 19, 2022 (GLOBE NEWSWIRE) — Biogen Inc. (Nasdaq: BIIB) announced that it has reached an agreement with Genentech, a member of the Roche Group, related to the commercialization and sharing of economics for glofitamab. Under the terms of the agreement, Biogen will have no payment obligations and will receive tiered royalties on potential net sales of glofitamab within the United States as part of the companies long-standing collaboration on antibodies targeting CD20.

Glofitamab is an investigational CD20xCD3 T-cell engaging bispecific antibody being developed by Roche for the treatment of B-cell non-Hodgkin’s lymphomas, including diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma, and other blood cancers¹. Glofitamab is based on a novel structural format called ‘2:1’, which is engineered to have two ‘Fab’ regions that bind to CD20 and one ‘Fab’ region which binds to CD3. This dual targeting activates and redirects a patient’s own T-cells to engage and eliminate cancer B cells.

Data from the Phase II NP30179 study investigating glofitamab in patients with relapsed/refractory (R/R) DLBCL have been submitted for review to the European Medicines Agency (EMA), and submissions to additional health authorities worldwide, including the U.S. Food and Drug Administration, are ongoing. If approved, glofitamab has the potential to be a first-in-class fixed-duration CD20xCD3 T-cell engaging bispecific antibody in DLBCL.

Genentech will have sole decision-making rights on the commercialization of glofitamab within the United States and, in the event of approval, Biogen is eligible to receive tiered royalties in the mid-single digits range on potential net sales of glofitamab within the United States.

Glofitamab, together with mosunetuzumab, is part of the Roche and Genentech CD20xCD3 antibody portfolio that seeks to address the unmet needs of people living with blood cancers. In January 2022, Biogen exercised the option to have joint decision-making rights related to the development and potential commercialization of mosunetuzumab, and Genentech will continue to lead the strategy and implementation of the program. The companies have had a collaboration on antibodies targeting CD20 since 1995.

These forward-looking statements may be accompanied by words such as “aim,” “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “intend,” “may,” “plan,” “potential,” “possible,” “will,” “would” and other words and terms of similar meaning. Drug development and commercialization involve a high degree of risk and only a small number of research and development programs result in commercialization of a product. Results in early stage clinical trials may not be indicative of full results or results from later stage or larger scale clinical trials and do not ensure regulatory approval. You should not place undue reliance on these statements or the scientific data presented.

These statements involve risks and uncertainties that could cause actual results to differ materially from those reflected in such statements, including without limitation, uncertainty of success in the development and potential commercialization of glofitamab; the risk that we may not fully enroll our clinical trials or enrollment will take longer than expected; unexpected concerns may arise from additional data, analysis or results obtained during our clinical trials; regulatory authorities may require additional information or further studies, or may fail or refuse to approve or may delay approval of our drug candidates, including glofitamab; the occurrence of adverse safety events; the risks of unexpected hurdles, costs or delays; failure to protect and enforce our data, intellectual property and other proprietary rights and uncertainties relating to intellectual property claims and challenges; product liability claims; and the direct and indirect impacts of the ongoing COVID-19 pandemic on our business, results of operations and financial condition.
