Regeneron Secures FDA Approval for Lynozyfic, Targets $600M Multiple Myeloma Market
SHERIDAN, WYOMING – July 8, 2025 – Regeneron has received accelerated approval from the U.S. Food and Drug Administration (FDA) for its bispecific antibody linvoseltamab, now branded as Lynozyfic, for the treatment of patients with relapsed or refractory multiple myeloma—unlocking a market potential estimated at $600 million.
While the therapy enters a space already led by Johnson & Johnson’s Tecvayli, approved in 2022, Regeneron is seeking to distinguish Lynozyfic through its efficacy profile and flexible dosing advantages. According to analysts at BMO Capital Markets, the approval is a “small win” for Regeneron, noting that Lynozyfic will be a “minor contributor to the company’s broader product portfolio.” The firm estimates around $600 million in potential revenues from the drug.
