QuantX Biosciences, a company leveraging computational power for drug discovery, has successfully closed an oversubscribed $85 million Series B financing round. The funding was co-led by prominent investors LAV and Sanofi Ventures, signaling strong confidence in the company's innovative approach. These proceeds are earmarked to accelerate the development of its pipeline of oral small-molecule therapeutics for immunology and inflammation.


Advancing Novel Oral Therapies

The new capital will primarily support the clinical advancement of QuantX's leading drug candidates. This includes a best-in-class STAT6 oral small molecule inhibitor and an IL-17 oral small molecule inhibitor, both targeting significant immune-mediated diseases. The financing enables the company to push these promising programs forward while continuing its discovery efforts for other oral therapies.

A Landmark Achievement

Wei Li, Interim Chief Executive Officer of QuantX, described the fundraising as a pivotal moment for the company's growth and pipeline development. In just three years since its inception, the company has built a world-class team and successfully advanced multiple first-in-class small molecule candidates to IND-enabling studies. This rapid progress highlights the efficiency of its discovery engine and strategic execution.

Strong Investor Endorsement

The financing round attracted a syndicate of distinguished new and existing investors, underscoring the industry's belief in QuantX's potential. Beyond co-leads LAV and Sanofi Ventures, the round saw participation from Hongshan and continued backing from early investors like OrbiMed and Creacion Ventures. This broad support provides a robust financial foundation for the company's ambitious clinical and discovery goals.

A Unique Value Proposition

Investors have praised QuantX's distinct ability to combine speed with quality in its drug development process. David Wang of OrbiMed highlighted this unique value proposition, noting the company's capacity to deliver best-in-class assets and advance them rapidly. This dual strength positions QuantX to effectively transform standards of care across a range of diseases with significant unmet needs.

Pioneering Computational Drug Design

At the core of QuantX's strategy is its sophisticated, computationally driven drug discovery platform. The company integrates physics-based modeling, advanced statistical methods, and computational chemistry to rapidly design and optimize drug candidates against clinically validated targets. This innovative method is engineered to enhance development efficiency and significantly improve the probability of success for new medicines.

From Inception to Clinical Stage

Founded in 2022 by veteran drug hunters Wayne Tang and Yax Sun, QuantX Biosciences has demonstrated a remarkable growth trajectory. The company was initially incubated by OrbiMed and Creacion Ventures, and with this latest financing, it has raised a total of $130 million to date. This substantial capital accumulation in a short period reflects the high potential of its platform and pipeline.


This successful $85 million Series B financing round marks a significant validation of QuantX Biosciences' platform and strategic direction. The capital injection empowers the company to accelerate its lead programs into the clinic and further expand its discovery pipeline. With strong backing and a powerful computational engine, QuantX is well-positioned to deliver transformative oral therapies to patients with immune-mediated and inflammatory diseases.
