Unlearn Closes $50 Million Series B

SAN FRANCISCO — Unlearn, developer of the first machine-learning technology that creates digital twins of patients in clinical trials to enable smaller, faster studies, has closed a $50 million Series B funding round. The financing was led by Insight Partners with participation from new investor Radical Ventures, as well as all of the company’s existing investors including 8VC, DCVC, DCVC Bio and Mubadala Capital Ventures. Through its investment, Dylan Morris, Managing Director, Insight Partners, has joined the Unlearn Board of Directors.

Unlearn works with pharma sponsors, biotech companies, and academic institutions to optimize human clinical trials with TwinRCTs. A TwinRCT is a randomized trial that uses machine learning and historical data to achieve a higher probability of success with a smaller number of patients. As in a traditional randomized controlled trial (RCT), patients are randomized to a treatment group and a control group; but, unlike a traditional trial, a digital twin is computed for every patient using a machine learning model trained on historical control data. The treatment effects for the primary and secondary outcomes can all be estimated with greater precision after correcting for each patient’s prognostic score derived from their digital twin. The European Medicines Agency (EMA) has published a draft qualification opinion indicating that this approach can be used for the primary analysis of phase II and III studies because it doesn’t introduce bias.

“By reducing the size of the control arm, more patients in a TwinRCT™ have access to a potentially beneficial experimental treatment instead of a placebo. Trials can be run faster and with the same resources so that patients can receive access to more effective treatments sooner,” said Dylan Morris, Managing Director at Insight Partners. “TwinRCTs™ not only increase trial efficiency but also provide rigorous evidence suitable for supporting regulatory decisions. We are excited to support the Unlearn team as they scale their TwinRCT™ solution to make clinical trials better for patients and for sponsors.”

“Unlearn continues to make rapid progress as we expand our work with global biopharmaceutical companies and advance productive conversations with global regulatory authorities who are committed to supporting innovation in clinical trials,” said Charles Fisher, Ph.D., founder and CEO of Unlearn. “This new financing is validation of our expanding footprint in clinical trials. We are proud to have the support of this world-class syndicate of investors and welcome both Insight Partners and Radical Ventures to the Unlearn team.”
