Pfizer's Mid-Stage Tilrekimig Data Poses Threat to Regeneron's Dupixent, Shares Dip
Summary
Regeneron's stock is down approximately 1.2% in premarket trading following Pfizer's announcement of mid-stage data for tilrekimig, a potential competitor to Regeneron's blockbuster drug, Dupixent. Pfizer anticipates late-stage results in 2027-28. Separately, Regeneron has expanded its development portfolio by adding new programs in neurology and ophthalmology.

Traders will closely watch Pfizer's progress with tilrekimig and any further details on Regeneron's new therapeutic programs.
