CAMBRIDGE, Mass., Nov. 5, 2020 /PRNewswire/ -- Synlogic, Inc. (Nasdaq: SYBX), a clinical stage company bringing the transformative potential of synthetic biology to medicine, today reported financial results for the third quarter ended Sept. 30, 2020, and provided an update on programs and progress.

"We are gaining momentum across our three clinical stage programs as we head into the end of the year," said Aoife Brennan, M.B. Ch.B., Synlogic's President and Chief Executive Officer. "We are ahead of schedule in moving SYNB8802—our investigational Synthetic Biotic for the treatment of Enteric Hyperoxaluria—into the clinic and initiated the Phase 2 SynPheny-1 study in PKU patients. On the corporate side, we have strengthened our leadership team with the addition of Dr. David Hava as Chief Scientific Officer. With a strong cash runway, we have the resources to execute on our key clinical milestones over the next 12 months, extending our lead as the premier platform for engineered Synthetic Biotic medicines."

"We are thrilled with the recent progress moving two programs forward in the clinic. Initiation of the Phase 2 SynPheny-1 study of SYNB1618 puts us on track to see data in PKU patients around the middle of next year," said Richard Riese, M.D., Synlogic's Chief Medical Officer. "The SynPheny-1 study will provide, for the first-time, data on the ability of SYNB1618 to lower blood Phe in a meaningful way for the 70% of PKU patients who are not served by existing oral therapies."

Dr. Riese further stated, "Our second metabolic program, SYNB8802 for Enteric Hyperoxaluria, has the potential to improve kidney health in an area of underappreciated need. Enteric Hyperoxaluria patients have no approved therapies to control dangerously high levels of urinary oxalate. We have initiated the Phase 1 trial and are looking forward to rapidly advancing SYNB8802 through clinical development."

2020 Priorities & Highlights

The Metabolic Portfolio:

• Initiation of a Phase 2 clinical trial to evaluate SYNB1618 in patients with Phenylketonuria (PKU), with data expected in the middle of 2021. SYNB1618 is an orally administered Synthetic Biotic medicine being developed as a potential treatment for PKU.
• Based on feedback from patients and caregivers Synlogic believes both current and emerging treatment options will continue to leave too many patients behind.
• Synthetic Biotic medicines offer potential for a safe, tolerable, reversible and oral therapy, which controls Phe levels by consuming Phe in the GI tract.
• Clinical sites have been activated across the United States and Synlogic expects to dose the first patient in the Phase 2 SynPheny-1 study of SYNB1618 by year-end.
• SynPheny-1 is designed to evaluate plasma Phe lowering of a solid oral formulation of SYNB1618 in adult PKU patients who do not benefit from, or do not tolerate, existing therapies such as Kuvan or Palynziq.
• In addition, the study is expected to provide valuable information to validate predictive pharmacodynamic and preclinical modeling.

• Advancement of SYNB8802 for the treatment of Enteric Hyperoxaluria. Synlogic is developing SYNB8802 to treat Enteric Hyperoxaluria.
• SYNB8802 has commenced a Phase 1 clinical study. The first healthy volunteer cohort was dosed in November 2020.
• Synlogic presented a poster at the American Society of Nephrology's (ASN) 2020 Kidney Week Virtual Event on SYNB8802, which demonstrated:
• In both nonhuman primate and mouse models of acute Hyperoxaluria, SYNB8802 significantly reduced oxalate levels.
• Proprietary in-silico simulations of predicted human exposure suggest SYNB8802 has the potential to achieve between 20% and 50% urinary oxalate lowering in patients at doses that have been well tolerated in prior trials of Synthetic Biotic medicines.

The Immunomodulation Portfolio:

• Continuation of the monotherapy arm of the Phase 1 clinical study of SYNB1891 in patients with advanced solid tumors or lymphoma. SYNB1891 is currently in Phase 1 clinical development in patients with advanced solid tumors or lymphoma.
• Enrollment in the Phase 1 trial continues per plan.
• Synlogic expects to share an update on the initial dose cohorts of the monotherapy arm of the Phase 1 clinical study before the end of the year, per plan.
• Initiation of the combination arm of the Phase 1 clinical study, with the anti-PD-1 antibody Tecentriq (atezolizumab), is expected in the first half of 2021.

Corporate Profile:

• Synlogic strengthens Leadership Team. Synlogic appointed Dr. David Hava, Ph.D., as Chief Scientific Officer.
• Dr. Hava brings over a decade of senior experience in research and development to Synlogic, including deep academic expertise in pillars of synthetic biology. Dr. Hava is an experienced drug hunter who has brought multiple programs from ideation into and through the clinic and has led numerous successful partnerships. Before joining Synlogic, Dr. Hava served as CSO at Metera Pharmaceuticals. He has also served as CSO at Pulmatrix Inc., where he led the Research and Development organization in the company's development of their delivery platform. Dr. Hava earned his Ph.D. in Molecular Biology and Microbiology at Tufts University and he completed his postdoctoral training at Harvard Medical School studying immunology and host-pathogen interactions.

Third Quarter 2020 Financial Results
As of September 30, 2020, Synlogic had cash, cash equivalents and short-term investments of $102.0 million.

For the three months ended Sept. 30, 2020, Synlogic reported a consolidated net loss of $13.2 million or $0.36 per share, compared to a consolidated net loss of $13.3 million or $0.39 per share, for the corresponding period in 2019.

Research and development expenses were $10.5 million for the three months ended September 30, 2020 compared to $10.6 million for the corresponding period in 2019.

General and administrative expenses for the three months ended September 30, 2020 were $3.0 million compared to $3.9 million for the corresponding period in 2019.

There was no revenue for the three months ending September 30, 2020 and $0.3 million for the three months ending September 30, 2019. Revenue for the prior period was associated with Synlogic's collaboration with AbbVie to develop Synthetic Biotic medicines for the treatment of irritable bowel disease, which was terminated in May 2020.

Financial Outlook
Based upon its current operating plan, Synlogic expects to have a projected cash runway into 2022.

About Synlogic
Synlogic™ is bringing the transformative potential of synthetic biology to medicine. With a premiere synthetic biology platform that leverages a reproducible, modular approach to microbial engineering, Synlogic designs Synthetic Biotic medicines that target validated underlying biology to treat disease in new ways. Synlogic's proprietary pipeline includes Synthetic Biotics for the treatment of metabolic disorders including Phenylketonuria (PKU) and Enteric Hyperoxaluria (HOX). The company is also building a portfolio of partner-able assets in immunology and oncology.

About PKU
Phenylketonuria (PKU) is an inherited metabolic disease that manifests at birth and is marked by an inability to break down Phe, an amino acid that is commonly found in many foods. Left untreated, high levels of Phe become toxic and can lead to serious neurological and neuropsychological problems affecting the way a person thinks, feels, and acts. Due to the seriousness of these symptoms, infants are screened at birth in many countries to ensure early diagnosis and treatment to avoid intellectual disability and other complications.

About Enteric Hyperoxaluria
Enteric Hyperoxaluria (HOX) is an acquired metabolic disorder caused by increased absorption of dietary oxalate, which is present in many healthy foods, making it almost impossible to control with diet alone. Enteric Hyperoxaluria often occurs as a result of a primary insult to the bowel, such as inflammatory bowel disease, short bowel syndrome, or as a result of surgical procedures such as Roux-en-Y bariatric weight-loss surgery.

Enteric Hyperoxaluria results in dangerously high levels of urinary oxalate, which causes progressive kidney damage, kidney stone formation, and nephrocalcinosis. Enteric Hyperoxaluria has no approved treatment options.
