US FDA Approves Samsung Bioepis’ Pyzchiva, a Biosimilar to Stelara

Overview

Samsung Bioepis Co., Ltd. announced that the US Food and Drug Administration (FDA) has approved the Biologics License Application (BLA) for Pyzchiva (ustekinumab-ttwe) subcutaneous injection and intravenous infusion as a biosimilar to Stelara (ustekinumab).

Pyzchiva Approval

• Pyzchiva has been approved for the treatment of 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, a provisional determination was granted for Pyzchiva’s interchangeability.

From the Team of Samsung Bioepis

• “The FDA approval of Pyzchiva as a biosimilar to Stelara is an important milestone for patients living with inflammatory conditions, as biosimilars can offer more choice and access to biologic treatments,” said Byoung In Jung, vice president and regulatory affairs team leader at Samsung Bioepis. 
• “In addition, biosimilars have a potential to reduce the financial burden of healthcare systems, especially in the US where biologics account for more than 46% of the annual drug spending. We will continue to reinforce our commitment to widen access to medicines by advancing our biosimilar pipeline for the benefits of patients, healthcare providers, and healthcare systems around the world,” she added.

FDA’s Approval of Pyzchiva

The FDA’s approval of Pyzchiva is based on a totality of evidence including analytical, non-clinical and clinical data demonstrating biosimilarity to Stelara, with no clinically meaningful differences in terms of safety, purity and potency: 

• The randomized, double-blind, three-arm, parallel-group, single-dose phase 1 clinical study (NCT04772274) demonstrated pharmacokinetics (PK) equivalence and comparable safety, tolerability, immunogenicity profiles between Pyzchiva (SB17) and Stelara in healthy volunteers. 
• The randomized, double-blind, multicenter phase 3 clinical study (NCT04967508), conducted in patients with moderate to severe plaque psoriasis, demonstrated biosimilarity of SB17 with Stelara through equivalent efficacy and comparable safety and PK profiles up to Week 28 and these primary results were published in the Journal of the American Academy of Dermatology. 
• In addition, the phase 3 study demonstrated biosimilarity of SB17 to Stelara up to week 28 in terms of efficacy, safety, pharmacokinetics, and immunogenicity, and these data were presented at the 2024 American Academy of Dermatology (AAD) Annual Meeting in March 2024.

• Samsung Bioepis and Sandoz entered into a commercialization agreement for SB17 (Pyzchiva) in September 2023 for the US, Canada,

European Economic Area (EEA), Switzerland, and United Kingdom (UK).
