CAMBRIDGE, Mass., Aug. 10, 2023 (GLOBE NEWSWIRE) -- Synlogic, Inc. (Nasdaq: SYBX), a clinical-stage biotechnology company advancing novel, oral, non-systemically absorbed biotherapeutics to transform the care of serious diseases, today reported financial results for the second quarter ended June 30, 2023, and provided an update on its pipeline programs.

“With our pivotal Phase 3 study, Synpheny-3, now underway, we are focused on trial execution and ensuring access, inclusion and an optimal experience for the patients who participate in this landmark study of a potential breakthrough in the management of PKU,” said Aoife Brennan, M.B. Ch.B., Synlogic President and Chief Executive Officer. “We were also pleased to share important regulatory milestones for the product candidate this quarter, including receipt of the FDA’s Fast Track designation, reenforcing the great medical need for this investigational medicine, and the World Health Organization (WHO)’s approval of the international non-proprietary name (INN) for SYNB1934: labafenogene marselecobac.”

Second Quarter 2023 and Recent Business Highlights

• Announced initiation of Synpheny-3, the global, pivotal Phase 3 study of efficacy and safety of labafenogene marselecobac (previously known as SYNB1934), as a treatment for patients with PKU (n=150)
• Received Fast Track designation from the U.S. Food and Drug Administration (FDA) for labafenogene marselecobac as a potential treatment for PKU
• WHO acceptance of the international non-proprietary name (INN) of labafenogene marselecobac for the drug candidate previously known as SYNB1934
• Presented data from multiple programs at 2023 Synthetic Biology: Engineering, Evolution & Design (SEED) conference

Second Quarter 2023 Financial Results and Financial Outlook

As of June 30, 2023, Synlogic had cash and cash equivalents of $46.3 million.

Revenue for the three months ended June 30, 2023 was $35 thousand compared to $152 thousand for the corresponding period in 2022. Revenue in both periods was primarily associated with the ongoing research collaboration with Roche for the discovery of a novel Synthetic Biotic for the treatment of inflammatory bowel disease.

For the three months ended June 30, 2023, Synlogic reported a consolidated net loss of $15.0 million, or $0.21 per share, compared to a consolidated net loss of $15.8 million, or $0.22 per share, for the corresponding period in 2022.

Research and development expenses were $11.8 million for the three months ended June 30, 2023, compared to $12.1 million for the corresponding period in 2022.

General and administrative expenses were $3.9 million for the three months ended June 30, 2023, compared to $4.1 million for the corresponding period in 2022.

Based upon its current operating plan and balance sheet as of June 30, 2023, Synlogic expects to have sufficient cash to be able to fund operations further into the second half of 2024.

About Synlogic 

Synlogic is a clinical-stage biotechnology company advancing novel, oral, non-systemically absorbed biotherapeutics to transform the care of serious diseases in need of new treatment options. The Company’s late-stage pipeline is focused on rare metabolic diseases, led by labafenogene marselecobac (previously known as SYNB1934), currently being studied as a potential treatment for phenylketonuria (PKU) in Synpheny-3, a global, pivotal Phase 3 study. Additional product candidates address diseases including homocystinuria (HCU), enteric hyperoxaluria, gout and cystinuria. This pipeline is fueled by the Synthetic Biotic platform, which applies precision genetic engineering to well-characterized probiotics. This enables Synlogic to create GI-restricted, oral medicines designed to consume or modify disease-specific metabolites – an approach well suited for PKU and HCU, both inborn errors of metabolism, as well as other disorders in which the disease–specific metabolites transit through the GI tract, providing validated targets for these Synthetic Biotics. Research activities include a partnership with Roche focused on inflammatory bowel disease (IBD), and a collaboration with Ginkgo Bioworks in synthetic biology, which has contributed to two pipeline programs to date.
