OSR Holdings and SillaJen have entered into a Memorandum of Understanding to collaboratively pursue the development of innovative therapeutics and enter the U.S. market

SEOUL, South Korea, April 23, 2024 /PRNewswire/ -- OSR Holdings, a global healthcare holding company, announced that it has signed a memorandum of understanding (MOU) with SillaJen, a Kosdaq-listed biotech firm with a pipeline of immuno-oncology drug candidates, to share technology and clinical development resources and launch a strategic collaboration between the two companies. Through the MOU, the two companies will explore various ways to collaborate to create synergies between current platform technologies and new drug candidates.

OSR Holdings was established in 2019 in South Korea as a "hub-and-spoke" business model, which has become more visible in the biopharma space over the past decade. The "hub-and-spoke" model, exemplified by companies like Roivant Sciences, PureTech Health and BridgeBio Pharma, enables centralized management of drug development strategies, clinical plans, and resource allocation by the holding company. The model allows the holding companies' subsidiaries to concentrate on the advancement of new drug assets and technological innovations. The model's scalability and resource efficiency are notably enhanced, especially as clinical phases of drug development progresses.

OSR Holdings' current portfolio includes Vaximm AG, a Swiss entity developing immuno-oncology therapeutics; Darnatein, a South Korean drug developer of osteoarthritis therapeutics; and RMC, a distributor of specialized medical devices. Vaximm AG, a venture spun out from Merck KGaA, has completed Phase 2a clinical trials for glioblastoma. Darnatein, established by Dr. Senyon Choe, a former researcher at one of the leading research institutes in the U.S., Salk Institute for Biological Studies, boasts a robust platform for cartilage and bone regeneration and is developing new drugs for other diverse disease indications based on this foundational technology.

SillaJen boasts a diverse pipeline of new drugs, including the SJ-600 series and BAL0891, and is leading the way in developing anti-cancer viruses based on its GEEV® platform. Known for its immune-evasion capabilities, GEEV® enables anti-cancer viruses to efficiently target affected areas. The SJ-600 series is an anti-cancer pipeline based on SillaJen's GEEV® platform. BAL0891, a mitotic checkpoint inhibitor, has advanced to Phase 1 clinical trials targeting solid tumors and will be conducted in the United States.

Sung Jae "Alex" Yu, COO of OSR Holdings, stated, "the signing of this MOU marks the two companies transitioning into strategic partners for the development of innovative drug technologies in the global immuno-oncology market. We eagerly anticipate exploring a variety of opportunities to further our relationship and collaborations with SillaJen, particularly in the U.S., the largest pharmaceutical market in the world."

A representative of SillaJen stated, "We can anticipate synergies by collaborating between a company that possesses original anti-cancer drug development technology and a company with global business expertise," and added, "Aside from our cooperation with existing partners, we will have the opportunity to present SillaJen's exceptional pipeline in the U.S. market."
