SAN DIEGO, Oct. 29, 2019 (GLOBE NEWSWIRE) -- Synthorx, Inc. (NASDAQ: THOR), a clinical-stage biotechnology company developing optimized therapeutics for cancer and autoimmune disorders, today announced the presentation of three posters at the upcoming Society for Immunotherapy of Cancer (SITC) 34th Annual Meeting in National Harbor, MD, from November 6-10, 2019. These posters will highlight the company’s lead product candidate THOR-707 and two of its other Synthorin™ cytokines for immuno-oncology.
We will present an update on the HAMMER study with a trial in progress poster. “HAMMER is a three-part global Phase 1/2 dose escalation and expansion study evaluating the safety and anti-tumor activity of THOR-707, our not-alpha IL-2 Synthorin, in patients with advanced or metastatic solid tumors. Part 1 of the study will determine the recommended phase 2 dose (RP2D) of THOR-707 as a single agent and part 2 will determine the RP2D of THOR-707 in combination with a PD-1 inhibitor. Part 3 of the study will continue to evaluate safety along with the anti-tumor activity of THOR-707 alone or in combination with a PD-1 or PD-L1 inhibitor as well as in combination or sequenced with other established and emerging immuno-oncology therapies via dose expansion.” said Joseph A. Leveque, M.D., Chief Medical Officer.
In addition, posters on IL-15 and IL-10 Synthorins will be presented. “IL-15 and IL-10 each have unique biological properties that are promising for the treatment of cancer, but in their unmodified forms have therapeutic limitations. Our work presented in the posters showcase the versatility of our Expanded Genetic Alphabet Platform, demonstrating how site-specific pegylation can improve the pharmacological and pharmacokinetic properties of IL-15, and enable the discovery of improved IL-10 variants” said Marcos E. Milla, Ph.D., chief scientific officer, Synthorx.
Details of the poster presentation are as follows. The full abstracts will be made available on the SITC website on November 5, 2019 at 8:00 a.m. ET.

About Synthorx
Synthorx, Inc. is a clinical-stage biotechnology company focused on prolonging and improving the lives of people with cancer and autoimmune disorders. Synthorx’ proprietary, first-of-its-kind Expanded Genetic Alphabet platform technology expands the genetic code by adding a new DNA base pair and is designed to create optimized biologics, referred to as Synthorins. A Synthorin is a protein optimized through incorporation of novel amino acids encoded by the new DNA base pair that enables site-specific modifications, which enhance the pharmacological properties of these therapeutics. The company’s lead immuno-oncology (IO) product candidate, THOR-707, a variant of IL-2, is in development in multiple tumor types as a single agent and in combination with an immune checkpoint inhibitor. The company was founded based on important discoveries by Dr. Floyd Romesberg and The Scripps Research Institute. Synthorx is headquartered in La Jolla, Calif.
