MEDIPOST Secures FDA Agreement for Single Pivotal Phase 3 Study of CARTISTEM

05 June 2026 | Friday | News


The regulatory pathway enables MEDIPOST to accelerate development of its cell therapy for knee osteoarthritis, leveraging Phase 3 data from South Korea and Japan together with real world evidence to support an earlier route to potential commercialisation in the United States.

MEDIPOST, a fully integrated commercial stage cell therapy biotechnology company, announced today that it has secured the FDA's agreement to conduct a single pivotal Phase 3 study for CARTISTEM® in the U.S. This milestone marks a significant step forward in MEDIPOST's mission to bring its first-in-class knee osteoarthritis treatment CARTISTEM® to patients in both the U.S. and Canada.

 

By securing this agreement, MEDIPOST seeks to accelerate CARTISTEM®'s U.S. development timeline while simultaneously improving the company's financial efficiency. Furthermore, the company now expects a significant reduction in the overall U.S. clinical development timeline and clinical development costs with an earlier BLA filing timepoint, which could facilitate an expedited commercial entry to the U.S. market than previously expected.

MEDIPOST secured the FDA's agreement by leveraging its successful Phase 3 clinical study data from both South Korea and Japan. In addition, its South Korea based Real-World Evidence (RWE) data from approximately 550 patients who were treated with CARTISTEM® a minimum of three years ago, will also be included in the proposed evidentiary package to the FDA as confirmatory evidence to support the anticipated outcome for the U.S. Phase 3 study.

Antonio Lee, Global President of MEDIPOST and CEO of MEDIPOST K.K. (Japan) and Co-CEO of MEDIPOST Inc. (U.S.), stated, "We will leverage the time & cost saving advantages secured through this agreement, together with our successful experience in conducting Phase 3 trials both in South Korea and Japan, to ensure the smooth execution of our U.S. Phase 3 study." He continued, "Together with the recent clinical success in Japan, this milestone catalyzes our U.S. commercialization strategy and global partnership discussions.", "We are also pleased to partner with the U.S. FDA and appreciate their willingness to show regulatory flexibility to support accelerating novel advanced therapeutic products' entry into the U.S. market."
