, May 8, 2020 /PRNewswire/ -- Synlogic, Inc. (Nasdaq: SYBX), a clinical stage company applying synthetic biology to beneficial microbes to develop novel, living medicines, today reported its financial results for the first quarter ended March 31, 2020.

"In the first quarter, we continued to advance our programs and enhance our Synthetic Biotic platform capabilities in synthetic biology, manufacturing and development.  While the coronavirus pandemic necessitated we update a number of our development plans, I am very grateful to our dedicated employees who have enabled us to continue to execute on our strategy under challenging circumstances," said Aoife Brennan, M.B., Ch.B., Synlogic's president and chief executive officer. "We look forward to showcasing our deep platform capabilities and expanding program portfolio at our upcoming virtual R&D event on May 27th, which will include more details on one of our newest and rapidly advancing programs in enteric hyperoxaluria."

2020 Priorities


  • Initiation of a Phase 2 clinical trial to evaluate a solid formulation of SYNB1618 in patients with phenylketonuria (PKU). SYNB1618 is an orally administered Synthetic Biotic medicine that is being developed as a treatment for PKU.
    • Synlogic intends to continue to work with sites to complete preparatory work, however as a result of the coronavirus pandemic it does not expect to be able to enroll subjects into its Phase 2 clinical trial of SYNB1618 until it is safe for patients to enter clinical trial sites.
    • The Phase 2 trial is designed to evaluate safety and tolerability of a solid formulation of SYNB1618 as well as its potential to lower blood phenylalanine levels in PKU patients. In addition, the study is expected to provide valuable information to validate predictive pharmacodynamic and preclinical modeling.
  • Evaluation of data from the monotherapy arm of the Phase 1 clinical study of SYNB1891 in patients with advanced solid tumors or lymphoma.  SYNB1891 is an intra-tumorally administered Synthetic Biotic medicine engineered to produce cyclic di-AMP, an agonist of the STING pathway, that is designed to serve as a dual innate activator of the immune system as a potential treatment for solid tumors or lymphoma. SYNB1891 is being evaluated as a monotherapy in an ongoing Phase 1 open-label, multicenter, dose escalation clinical trial (NCT04167137) in patients with advanced solid tumors or lymphoma.
    • While this clinical trial and most clinical sites have remained open and enrolled patients have continued on study, Synlogic expects slower enrollment of new patients as a result of the coronavirus pandemic, which has the potential to impact the availability of data in 2020. 
  • Continued development of patient and commercialization-appropriate drug presentations of SYNB1618.
    • Synlogic has developed and manufactured a solid formulation of its Synthetic Biotic SYNB1618 that it plans to use in future clinical trials and continues to evaluate and develop different drug presentations (e.g. capsule, pressed pill, sachet) for eventual commercialization.
  • Advancement of new Synthetic Biotic programs in metabolic diseases with high unmet medical need.
    • Synlogic is conducting preclinical studies of Synthetic Biotic medicines to treat enteric hyperoxaluria, an acquired metabolic disorder in which patients develop recurrent kidney stones due to elevated urinary oxalate levels and are at an increased risk of kidney failure. Synlogic expects to move a clinical candidate in its enteric hyperoxaluria program, into IND-enabling studies in 2020.
    • In addition, Synlogic is also developing Synthetic Biotic medicines for the treatment of other metabolic diseases, including maple syrup urine disease (MSUD), a rare inherited metabolic disease caused by defective enzymes that metabolize branched chain amino acids (BCAAs) which are components of protein.
  • Publication and presentation of data demonstrating the breadth and potential of its Synthetic Biotic platform. 
    • On March 8th, Nature Communications published a Perspective authored by Synlogic scientists entitled, "Developing a new class of engineered live bacterial therapeutics to treat human diseases."  The paper, which highlights the considerations for the design and development of engineered live bacteria, including Synthetic Biotic medicines, is available on the Synlogic website on the Presentations and Publications page of the Investors and Media section.
  • On May 27th, 2020 Synlogic will host its first virtual R&D event 
    • The webcast event will highlight the Company's progress in developing its platform capabilities and pipeline of rare metabolic disease programs for internal prosecution and programs in immunomodulation for potential partnering. Dr. David Goldfarb, Professor of Medicine and Physiology at NYU School of Medicine, Clinical Chief of the Nephrology Division at NYU Langone Health, and Chief of the Nephrology Section and Director of the Hemodialysis Unit at the New York VA Medical Center in Manhattan will also present an overview of enteric hyperoxaluria. A link to the live webcast will be available on Synlogic's website on the News & Events page of the Investors and Media section.

First Quarter 2020 Financial Results
As of March 31, 2020, Synlogic had cash, cash equivalents, and short-term investments of $114.2 million.

For the three months ended March 31, 2020, Synlogic reported a consolidated net loss of $15.8 million, or $0.46 per share, compared to a net loss of $12.9 million, or $0.51 per share, for the corresponding period in 2019.

Research and development expenses were $12.7 million for the three months ended March 31, 2020 compared to $10.4 million for the corresponding period in 2019. The increase in expenses was primarily due to use of synthetic biology services provided under Synlogic's collaboration with Ginkgo and increased clinical activities associated with the SYNB1618 bridging study and the SYNB1891 Phase 1 clinical trial.

General and administrative expenses for the three months ended March 31, 2020 were $3.8 million compared to $3.7 million for the corresponding period in 2019.

Revenue was $0.1 million for the three months ended March 31, 2020 compared to $0.3 million for the three months ended March 31, 2019. Revenue is associated with services performed under the Synlogic's collaboration with AbbVie to develop a Synthetic Biotic medicine for the treatment of IBD.

About Synlogic
Synlogic is pioneering the development of a novel class of living medicines, Synthetic Biotic medicines, based on its proprietary drug development platform. Synlogic leverages the tools and principles of synthetic biology to genetically engineer beneficial microbes to perform or deliver critical functions missing or damaged due to disease. When delivered orally, Synthetic Biotic medicines are designed to function in the gut to compensate for the dysfunctional metabolic pathway and have a systemic effect, with the potential to significantly improve symptoms of disease for affected patients. The Company's lead program in this area, SYNB1618, targets PKU. In addition, the Company is leveraging the broad potential of its platform to create Synthetic Biotic medicines for the treatment of more common diseases, including inflammatory and immune disorders, and cancer. Synlogic's first immuno-oncology program, SYNB1891, is in clinical development for the treatment of solid tumors and lymphoma.  Synlogic is collaborating with AbbVie to develop Synthetic Biotic-based treatments for inflammatory bowel disease (IBD).
