Bridge Biotherapeutics, a South Korean clinical-stage biotech company, has agreed to sell its controlling stake to U.S. digital asset investment firm Parataxis Holdings LLC for KRW 25 billion (approximately $18.7 million), marking a dramatic pivot from pharmaceutical development to Bitcoin treasury management following a series of clinical trial failures.
The transaction, announced June 20, 2025, will transform the KOSDAQ-listed company into "Parataxis Korea," creating what the firms describe as South Korea's first institutionally-backed Bitcoin treasury platform on public markets. The deal is subject to shareholder approval expected in August 2025.
Clinical Setbacks Drive Strategic Pivot
Bridge Biotherapeutics' decision to pivot comes after significant setbacks in its drug development pipeline. The company's lead candidate BBT-877, designed to treat idiopathic pulmonary fibrosis (IPF), failed to demonstrate statistical significance compared to placebo in Phase 2 clinical trials, with top-line results released in April 2025 showing the primary evaluation index failed to meet endpoints.
The IPF candidate had a troubled development history. Originally transferred to German pharmaceutical giant Boehringer Ingelberg in 2019, BBT-877 was returned to Bridge Bio in November 2020, prompting the company to conduct its own Phase 2 clinical trial.
Bridge Bio's pipeline suffered another blow with BBT-401, a treatment for ulcerative colitis, which was discontinued in February 2023 after Phase 2a clinical trials showed a lower response rate than the placebo group.
New Leadership and Strategic Direction
Under the new ownership structure, Edward Chin, founder and CEO of Parataxis Holdings and co-founder of Parataxis Capital Management, will join Bridge Bio's board of directors. Andrew Kim, a partner at Parataxis Capital, will assume the CEO role and also join the board.
James Jungkue Lee, Bridge Bio's co-founder, will continue leading the remaining biotech operations and maintain his board position, ensuring continuity for any ongoing pharmaceutical activities.
"Inspired by the growing interest in BTC treasury strategies seen in companies like MicroStrategy in the US and Metaplanet in Japan, we believe institutional interest in this space is increasing globally," said Andrew Kim. "We see South Korea as an important market in the evolution of BTC adoption."
Bitcoin Treasury Strategy
Parataxis Holdings, headquartered in New York, operates as an institutional investment platform focused on Bitcoin-based asset management among digital assets. The firm plans to leverage Bridge Bio's public listing to provide institutional investors with exposure to Bitcoin treasury strategies in the Korean market.
"We are incredibly excited to create the first BTC treasury company in South Korea backed by an institutional-grade platform," said Edward Chin. "Given the strategic nature of BTC on the global stage and its finite supply, we believe that building and growing a company like Parataxis Korea and accumulating a BTC treasury will benefit our shareholders as well as the country over the long run."
The transaction involves investment through Parataxis Korea Fund No. 1, a Korean-affiliated fund of Parataxis Holdings. The firm indicated it is simultaneously closing another fund with substantially the same strategy and launching additional fund vehicles.
Market Context and Implications
Founded in 2015 and listed on KOSDAQ in 2019, Bridge Biotherapeutics represents a notable example of biotech companies pivoting away from traditional pharmaceutical R&D following clinical failures. The company's transformation into a Bitcoin treasury vehicle reflects broader trends in digital asset adoption among institutional investors.
Parataxis Capital Management, founded in 2019, manages multiple hedge fund vehicles and provides sub-advisory services for institutional allocators, family offices, and high-net-worth individuals in the digital asset sector.
The transaction is being advised by Shin & Kim LLC as legal counsel and Deloitte as financial advisor to Parataxis Korea Fund I LLC. Additional details regarding the transaction are expected following the shareholder meeting scheduled for August 2025.
