Synthorx obtains $63 million financing to develop novel protein therapeutics

| By | Drug Development, Innovative Medicines, R&D

Synthorx Inc. announced the completion of a $63 million Series C financing, led by OrbiMed and joined by new investors, Medicxi and Osage University Partners, and existing investors, Avalon Ventures, RA Capital Management, and Correlation Ventures.

The proceeds of the financing will be used to advance the company’s pipeline of Synthorin™ cytokines, including an IL-2 tuned specifically for activity on certain immune cells. Using the company’s expanded genetic alphabet technology based on a breakthrough in synthetic biology, Synthorin cytokines are designed to selectively tune receptor pharmacology and extend half-life. These properties allow for efficacious immune system activation with convenient dosing schedules and without safety limitations to enhance the antitumor activity of leading immuno-oncology approaches, including checkpoint inhibitors, cancer vaccines, CAR-T therapies, and oncolytic viruses.

Synthorx Inc. is a biotechnology company using synthetic biology to discover and develop novel protein therapeutics. Synthorx’s expanded genetic alphabet platform has the unique ability to drive the site-specific incorporation of multiple synthetic amino acids into proteins thereby tuning receptor specificity important for improving efficacy and safety. In addition, their engineered organisms provide the ability to manufacture these improved proteins, called Synthorins, with the required fidelity and yield. The unique Synthorx platform expands the chemical and structural repertoire of protein therapeutics and uncovers new ways to modulate pharmacological properties of biologics, not possible with other technologies. The company was founded based on important discoveries in Dr. Floyd Romesberg’s lab at The Scripps Research Institute in conjunction with Avalon Ventures, which housed Synthorx in its incubator, COI Pharmaceuticals, Inc. The company is headquartered in La Jolla, California, USA.
