Biocon Biologics Announces Positive Results from Phase 3 Study of Yesintek™ Biosimilar to Ustekinumab for Chronic Plaque Psoriasis

BRIDGEWATER, N.J., United States and BENGALURU, Karnataka, India : March 7, 2025 -- Biocon Biologics Ltd. (BBL) , a fully integrated global biosimilars company and subsidiary of Biocon Ltd. (BSE code: 532523, NSE: BIOCON), today announced the successful results of a pivotal Phase 3, randomized, double-blind, parallel group, multicenter study comparing Yesintek™ (Biocon Biologics’ biosimilar to Ustekinumab, called YESINTEK) with reference product Stelara (Ustekinumab) in adult patients with moderate to severe chronic plaque psoriasis (PsO). The data are being presented at the 2025 American Academy of Dermatology (AAD) Annual Meeting in Orlando, Florida.

The study demonstrated equivalent efficacy, safety, immunogenicity, and pharmacokinetics between YESINTEK and the reference product Stelara (Ustekinumab), marking a significant milestone for Biocon Biologics in advancing the accessibility of biosimilar therapies for patients worldwide.

Elena Wolff-Holz, M.D., Global Head Clinical Development, Biocon Biologics said, “The positive results from this Phase 3 study reaffirm the quality and therapeutic equivalence of YESINTEK compared to reference product Ustekinumab. This milestone underscores our commitment to providing cost-effective, high-quality biosimilars to patients with chronic conditions like psoriasis, expanding access to critical treatments globally.”

The primary efficacy endpoint, percentage change from baseline in Psoriasis Area and Severity Index (PASI) score at Week 12, demonstrated that YESINTEK was equivalent to reference Stelara (Ustekinumab), with both treatments showing similar improvement in PASI scores. The mean difference between the two groups was 0.68%, falling within the predefined equivalence margins for both the U.S. Food and Drug Administration (U.S. FDA) and European Medicines Agency (EMA).

The safety profile of YESINTEK was similar to the reference product Stelara (Ustekinumab) through the duration of the study.

The pharmacokinetic and immunogenicity profiles of YESINTEK were found to be similar to those of reference Stelara (Ustekinumab), with no significant differences in efficacy or safety outcomes between the two treatments. Additionally, the study assessed the impact of switching from reference Stelara (Ustekinumab) to YESINTEK at Week 16, with results showing continued efficacy and safety through Week 52.

Uwe Gudat, M.D., Chief Medical Officer, Biocon Biologics said, “The results from this study show convincingly once more that in-vitro analytical comparability translates well into in-vivo clinical performance. The study reinforces the confidence we can have in the biosimilar regulatory pathways and the principles they are built on. Specifically, for YESINTEK the study shows that it offers an effective, safe, and comparable alternative to reference Ustekinumab in the treatment of moderate

to severe chronic plaque psoriasis and by extension the other indications for which Ustekinumab is indicated. YESINTEK is another important addition to our portfolio of affordable biologics that promise improved patient care by providing a cost-effective treatment option without compromising clinical outcomes.”

The study is being presented as:

Poster Title: Randomized, double-blind, parallel group, multicenter, Phase 3 study to demonstrate equivalent efficacy and to assess safety, immunogenicity and pharmacokinetics of BMAb-1200 compared to reference Ustekinumab in adult subjects with moderate to severe chronic plaque psoriasis

About YESINTEK

YESINTEK is a biosimilar medicine to Ustekinumab, a monoclonal antibody that targets interleukins IL-12 and IL-23, which play a key role in the immune-mediated pathogenesis of psoriasis and other autoimmune diseases. The Phase 3 study enrolled 384 adult patients aged 18-80 years who had a confirmed diagnosis of moderate to severe chronic plaque psoriasis. The primary objective was to demonstrate the equivalent efficacy of YESINTEK and reference Stelara (Ustekinumab), while assessing secondary outcomes related to safety, tolerability, immunogenicity, and pharmacokinetics. Additionally, the study assessed the impact of switching from reference Stelara (Ustekinumab) to YESINTEK. The U.S. FDA approved YESINTEK in December 2024.

YESINTEK has been approved by the US FDA for the treatment of adult patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy, active psoriatic arthritis, moderately to severely active Crohn’s disease and moderately to severely active ulcerative colitis. Additionally, it has been approved for pediatric patients 6 years and older with moderate to severe plaque psoriasis, who are candidates for phototherapy or systemic therapy and active psoriatic arthritis.
