Listen to the news

Regeneron Pharmaceuticals (REGN) has caught investors attention after unveiling promising Phase 1/2 data for its multiple myeloma candidate Lynozyfic, along with fresh progress in gene writing and high profile scientific conference appearances.

Those Lynozyfic results and the new gene writing collaboration have landed against a strong backdrop, with Regeneron’s 90 day share price return of 26.66 percent pointing to building momentum.
