Soteria Biotherapeutics, Inc. (“Soteria”), a privately-held, immuno-oncology company focused on developing a next generation of switchable bispecific T-cell engagers to treat patients with solid tumor cancers, today announced a $42 million Series A financing led by Roche Venture Fund and 5AM Ventures with participation from other leading investors, including M Ventures, Novartis Venture Fund and Alexandria Venture Investments.

Soteria’s T-LITE™ T-cell engagers are selectively switched on through oral administration of a small-molecule activator to modulate potent T-cell activity by controlling the timing, duration, and level of bispecific complex formation. This switchable activity enables precise on/off control over the timing and magnitude of T-cell redirection and cytotoxic activity. Unlike conventional T-cell engagers which lack a control switch and therefore are associated with significant side effects, Soteria’s T-LITE therapies are being designed to allow physicians to modulate T-cell activity to maximize efficacy while minimizing side effects.

“Soteria’s technology has the potential to revolutionize the T-cell engager field with its proprietary approach designed to control and target potent biologic immune activators to attack tumors,” said Nisha Marathe, investment director at Roche Venture Fund. “Specifically, we believe the T-LITE technology is highly differentiated, where the potent activity of a T-cell engager can be selectively switched on by small-molecule activators to direct tumor cytotoxicity and reduce cytokine release syndrome, ultimately resulting in a therapy with potentially greater safety and efficacy.”

“These funds will support the advancement of our technology and allow us to build a pipeline of T-LITE development candidates with potential in well validated cancer targets,” said Kristine Ball, chief executive officer of Soteria. “We appreciate the confidence and vision this syndicate of premier investors has shown in our opportunity to disrupt the T-cell engager field and our potential to create differentiated, potent therapies against solid tumors.”
