• Validates technological prowess of GAIA platform and intensifies global co-development effort, including the existing partnership with Lilly Catalyze360-ExploR&D
• Funds to accelerate Alzheimer's and immune disease drug development, expanding GAIA-based pipeline

SEOUL, South Korea, July 14, 2025 /PRNewswire/ -- Illimis Therapeutics today announced the successful completion of a 58 billion KRW ($42 million) Series B financing. The Series B round saw strong participation from both existing and new investors, demonstrating high industry confidence in Illimis Therapeutics' vision and technology. Eight existing investors, including DSC Investment, Woori Venture Partners, Korea Development Bank, Aju IB Investment, Quad Asset Management, Company K Partners, GS Ventures, and Dayli Partners, reaffirmed their commitment. They were joined by ten new investors: LB Investment, TS Investment, Shinhan Venture Investment, S&S Investment, Hana Ventures, Maple Investment Partners, A Ventures, IMM Investment, Schmidt, and Industrial Bank of Korea.

The proceeds will be used to accelerate the development of GAIA-based Alzheimer's Disease therapeutics, expand its target indications to various immune disorders, and broaden its pipeline of potential blockbuster drug candidates. The company is actively pursuing early-stage collaborations with global pharmaceutical companies and research institutions to add value to internal programs.

"In the evolving landscape of new drug development where the limitations of existing medications are continually being overcome, Illimis' differentiated platform technology is expected to emerge as a next-generation treatment option for neuro-immune diseases with high unmet medical needs," said Yohan Kim, Senior Managing Director at DSC Investment, who led this investment round and has also been appointed to the board of directors.

Jiwoong Chun, Managing Director at Woori Venture Partners and an active board member and investor since the company's inception, added, "Illimis is a prime example of a smart Korean biotech unlocking global markets with proprietary innovation and capital efficiency."

Illimis has recently been selected for the '2025 Global Joint Research to Defeat Dementia' led by the Ministry of Health and Welfare and the Korean Dementia Research Center, securing KRW 2.2 million ($1.6 million) in funding over three years, further validating its technological capabilities. This initiative aims to develop Alzheimer's therapeutics through global joint research leveraging the GAIA platform, positioning Illimis at the center of international collaboration.

Furthermore, in October 2024, Illimis partnered with Eli Lilly and Company (Lilly)'s Catalyze360-ExploR&D, a core pillar of external innovation at Lilly dedicated to deploying world-leading research and development capabilities and scientific know-how to accelerate partner science. Under this research collaboration, Illimis and Lilly have been cooperating to advance the platform construct for applications in neurodegenerative diseases. Illimis has also strengthened its global pharma collaborations by winning the 2023 BMS Innovation Square Challenge and joining Johnson & Johnson's global incubator network as a member company of JLABS Singapore in 2024.

To further enhance its drug development competitiveness, Illimis Therapeutics operates a Scientific Advisory Board (SAB). The SAB includes Dr. Greg Lemke, Emeritus Professor at the Salk Institute and a world-renowned expert in TAM Biology, and Dr. Morgan Sheng, a leading neuroscientist at the Broad Institute who previously served as Vice President of Neuroscience at Genentech. These experts provide strategic guidance across the entire R&D lifecycle, including pipeline development, candidate discovery, clinical trial design, etc., and play a pivotal role in strengthening Illimis Therapeutics' global partnerships.

"This investment, government grants, and partnership with Lilly will enable us to accelerate our efforts to conquer diseases with high unmet clinical needs based on a comprehensive understanding of TAM biology and establish global leadership in TAM biology," said Sanghoon Park, CEO of Illimis Therapeutics. "We will continue to focus on innovative new drug development centered around the GAIA platform and provide tangible treatment options to patients worldwide through early R&D collaboration models."
