On June 19, 2026, Janssen filed a BPCIA litigation, Case No. 1:26-cv-01754 (E.D. Va.) against Alvotech, alleging infringement of 14 of Janssen’s manufacturing patents by proposed Simponi® / Simponi Aria® (golimumab) biosimilar AVT05. Alvotech resubmitted its aBLA for AVT05 earlier in June after receiving a Complete Response Letter from the FDA in November 2025 (previously reported aBLA Resubmissions: Xbrane’s Xlucane (ranibizumab) and Alvotech’s AVT05 (golimumab) and AVT06 (aflibercept); FDA Issues Complete Response Letter for Alvotech’s Simponi® (golimumab) Biosimilar AVT05).
This is the second BPCIA litigation related to a Simponi® / Simponi Aria® biosimilar, following Case No. 1:26-cv-00222 (D. Del.) filed in March 2026 against Accord and Bio-Thera’s Immgolis™ / Immgolis Intri™ (golimumab-sldi) (previously reported Janssen Files First BPCIA Suit Over Simponi® (golimumab) Biosimilar). The Complaint against Alvotech asserts four patents against AVT05 that have not previously been asserted in litigation.
Simponi® / Simponi Aria® patents are also facing IPRs filed by Accord and Bio-Thera that are awaiting institution decisions: IPR2026-00256, -00257, -00258, and -00259 (previously reported Accord and Bio-Thera File Four IPRs Challenging Janssen Simponi® Patents).
Johnson & Johnson reported U.S. sales of $1.2B for Simponi® / Simponi Aria® in 2025.
