On March 4, 2024, the PTAB granted Biocon and Janssen’s joint motion to terminate IPR2023-01444 due to a settlement reached prior to an institution decision. The parties announced in a press release that their settlement and license agreement allows Biocon to commercialize Bmab 1200, its proposed biosimilar to Stelara^® (ustekinumab), in the U.S. by February 2025, subject to FDA approval. This IPR was the last pending biosimilar patent proceeding related to Stelara^®.

The press release also noted that the FDA has accepted the aBLA for Bmab 1200 for review. Currently, there are at least four other pending aBLAs for Stelara^® biosimilars, including Alvotech and Teva’s AVT04, Celltrion’s CT-P43, Samsung Bioepis’s SB17, and Accord BioPharma’s DMB-3115.

Stelara^® had U.S. sales of $7 billion in 2023.

We continue to monitor this aBLA.  For more information about Stelara^® and biosimilar-related patent disputes, please visit BiologicsHQ.com.
