Synlogic Announces Synthetic Biotic for Gout Developed in Partnership with Ginkgo Bioworks

SYNB2081 is the second clinical drug candidate developed through the partnership between Ginkgo and Synlogic

Synlogic, Inc. (Nasdaq: SYBX), a clinical-stage biotechnology company developing medicines for metabolic and immunological diseases through its proprietary approach to synthetic biology, today announced a new drug candidate for the treatment of gout developed in partnership with Ginkgo Bioworks (NYSE: DNA), the leading horizontal platform for cell programming. The new candidate, SYNB2081, is a Synthetic Biotic and is the second product to advance to clinical development through a research collaboration between Synlogic and Ginkgo, following the investigational new drug candidate SYNB1353 for the potential treatment of homocystinuria (HCU).

Gout is a complex form of inflammatory arthritis that occurs when excess uric acid in the body forms crystals in the joints. Patients experience symptoms such as intense joint pain, inflammation and redness, and limited range of motion in the affected joints. Current treatment options present limitations in both safety and efficacy, highlighting a need for new approaches. In addition, gout is a recognized risk factor in chronic kidney disease. SYNB2081 is a Synthetic Biotic designed to lower uric acid.

"With our second drug candidate into clinical development, this not only demonstrates the value of combining Ginkgo's platform with our Synthetic Biotic platform, but also highlights the potential to develop Synthetic Biotics across a range of diseases, giving us the potential to provide meaningful new treatment options to patients in need," said Dr. David Hava , Chief Scientific Officer, Synlogic.

SYNB2081 is named after one of the largest and best-preserved Tyrannosaurus rex specimens in the world. Nicknamed "Sue," the specimen is housed at the Field Museum in Chicago and is officially named FMNH PR 2081. Data from "Sue" suggests that dinosaurs like the Tyrannosaurus rex suffered from gout much in the same way as other reptiles and birds do.

"The advancement of SYNB2081 and SYNB1353 are clear indicators of the transformative platform Synlogic has created to develop new Synthetic Biotics through synthetic biology," said Patrick Boyle , Head of Codebase for Ginkgo. "We're honored to work with the Synlogic team in this pioneering next step to potentially help patients living with gout. As we've seen the Synlogic pipeline develop over the past year, we're eager to continue supporting Synlogic in generating additional therapeutic candidates."

Synlogic is a clinical-stage biotechnology company developing medicines through its proprietary approach to synthetic biology. Synlogic's pipeline includes its lead program in phenylketonuria (PKU), which has demonstrated proof of concept with plans to start a pivotal, Phase 3 study in the first half of 2023, and additional novel drug candidates designed to treat homocystinuria (HCU) and enteric hyperoxaluria. The rapid advancement of these potential biotherapeutics, called Synthetic Biotics, has been enabled by Synlogic's reproducible, target-specific drug design. Synlogic uses programmable, precision genetic engineering of well-characterized probiotics to exert localized activity for therapeutic benefit, with a focus on metabolic and immunologic diseases. In addition to its clinical programs, Synlogic has a research collaboration with Roche on the discovery of a novel Synthetic Biotic for the treatment of inflammatory bowel disease. Synlogic has also developed two drug candidates through a research collaboration with Ginkgo Bioworks: SYNB1353, designed to consume methionine for the potential treatment of HCU, and SYNB2081, designed to lower uric acid for the potential treatment of gout.
