The company has already progressed two programmes into investigational new drug application (IND)-enabling trials since its founding and a Series A funding round raise.

Seismic Therapeutic founder, president and CEO Jo Viney stated: “We are delighted to secure the support of such a strong syndicate of investors who believe in Seismic’s ability to pioneer a new era of immunology drug development integrating machine learning. 

“This financing enables us to continue our momentum and advance both of our exciting lead programmes into the clinic. We believe the time is right to harness advances in machine learning to discover the next generation of biologics drugs to improve the lives of patients with autoimmune diseases.”
