CAMBRIDGE, Mass., March 17, 2022 (GLOBE NEWSWIRE) — Synlogic, Inc. (Nasdaq: SYBX), a clinical-stage biotechnology company developing medicines for metabolic and immunological diseases through its proprietary approach to synthetic biology, today reported financial results for the fourth quarter and full year ending December 31, 2021 and provided an update on pipeline programs.

“2021 was a transformational year for Synlogic highlighted by proof of concept for our lead program in phenylketonuria (PKU),” said Aoife Brennan, M.B. Ch.B., Synlogic President and Chief Executive Officer. “Despite the devastating burden of this disease, a large majority of people living with PKU remain in need of an efficacious, safe, oral medication. We look forward to sharing Phase 2 data in the first half of this year as we continue plans to initiate Phase 3 later this year. We are also excited for clinical data readouts from our homocystinuria (HCU) and enteric hyperoxaluria programs, as well as research progress including our ongoing collaborations with Ginkgo Bioworks and Roche.”

Recent Portfolio Highlights

SYNB1618 and SYNB1934: In Development for the Treatment of PKU

  • PKU is a rare metabolic disease that can result in irreversible cognitive and neurological damage. Approximately 75% of people with PKU remain untreated, reflecting limitations of current therapies. SYNB1618 and SYNB1934 are non-systemically absorbed, oral drug candidates being studied for both adjunctive and monotherapy treatment of PKU.

  • In September 2021, Synlogic reported positive interim results from the Phase 2 SynPheny-1 study for SYNB1618, with clinically meaningful and statistically significant reduction of plasma Phe levels in patients with PKU. Based on this achieved proof of concept, the Company began preparations for Phase 3 development.

  • In parallel, Synlogic added an arm to the Phase 2 Synpheny-1 study for SYNB1934, a next-generation drug candidate for PKU designed for greater potency in Phe reduction. This additional arm in Synpheny-1 followed positive results with SYNB1934 in healthy volunteer studies.

  • In H1 2022, Synlogic expects to announce additional data from the Synpheny-1 study and, based on those findings, which of the two candidates will proceed to Phase 3 and potential commercialization.

SYNB1353: In Development for the Treatment of HCU

  • In November 2021, Synlogic and Ginkgo Bioworks announced the nomination of SYNB1353, a drug candidate designed to consume methionine for the treatment of HCU. Like PKU, HCU is an inherited rare metabolic disease caused by an inborn error of metabolism that results in significant disease burden, including intellectual disability and thromboembolism.

  • During 2022, the Company plans to submit an investigational new drug application (IND), initiate clinical trials and, in H2 2022, report Phase 1 healthy volunteer data for SYNB1353.

SYNB8802: In Development for the Treatment of Enteric Hyperoxaluria

  • Enteric hyperoxaluria, a leading cause of recurrent kidney stones, is a chronic, progressive disease that can lead to chronic kidney disease (CKD) and end-stage renal disease (ESRD), and for which there is currently no FDA-approved treatment.

  • Synlogic demonstrated proof of mechanism for SYNB8802 in enteric hyperoxaluria in 2021, and it is currently being evaluated in patients who have undergone Roux-en-Y gastric bypass surgery, with proof-of-concept data from this study expected in 2022.

Preclinical Pipeline

  • Synlogic plans to advance research programs to address metabolic and immunologic diseases, including wholly owned programs targeting inflammatory bowel disease and hyperuricemia (gout), diseases for which the Synthetic Biotic clinical profile of orally-administered, non-systemically absorbed biotherapeutics is particularly compelling.

  • The Company’s research collaboration with Roche to develop a Synthetic Biotic for the treatment of inflammatory bowel disease continues to progress.

  • Synlogic and Ginkgo continue to advance their long-term strategic platform collaboration with multiple undisclosed metabolic and immunology programs now in preclinical development.
