What happened?

Formation Bio has established a new subsidiary, Bleecker Bio, to develop Lynk Pharmaceuticals’ LNK01006, a next-generation allosteric TYK2 inhibitor designed to penetrate the central nervous system (CNS). Formation secured global rights (excluding greater China) in a deal valued at up to $605 million, with Lynk receiving an upfront payment, potential milestones, royalties, and a minority equity stake in Bleecker Bio.​

Why does it matter?

LNK01006 targets immune-signaling pathways in the CNS, offering potential new treatments for autoimmune and inflammatory conditions. The deal expands Formation’s immunology portfolio and highlights a strategic approach to drug development by leveraging AI and clinical expertise to accelerate trials and reduce costs.​

Who’s behind it?

Formation Bio, a New York-based biotech backed by VC Pacific Bridge NY. Lynk Pharmaceuticals, based in China, brings extensive industry experience through CEO Zhao-Kui (ZK) Wan, former head of chemistry at Johnson & Johnson and Pfizer.​

How was it achieved?

Formation’s “Known In New” strategy applies validated mechanisms to novel therapeutic areas. The company uses AI to streamline clinical development and de-risk assets, combining robust data sets with expert human insight. LNK01006 recently received FDA clearance for in-human trials, with a phase 1 study planned for the first half of 2026.​

What’s next?

Bleecker Bio will lead the development of LNK01006, initiating a phase 1 clinical trial in early 2026. Formation aims to translate the compound’s scientific potential into meaningful patient outcomes through its AI-enabled clinical development platform.​
