FDA approves Imuldosa (ustekinumab-srlf), a biosimilar to Stelara, for treating psoriasis, psoriatic arthritis, Crohn disease, and ulcerative colitis in both adults and pediatric patients. Imuldosa, initially developed as DMB-3115, demonstrated similar pharmacokinetic, safety, tolerability, and efficacy profiles to Stelara, adhering to FDA biosimilar guidance. This marks the fifth FDA approval for an ustekinumab product, with Imuldosa anticipated to launch in the first half of 2025.
