CAMBRIDGE, Mass., May 13, 2021 /PRNewswire/ -- Synlogic, Inc. (Nasdaq: SYBX), a clinical stage company bringing the transformative potential of synthetic biology to medicine, today reported financial results for the first quarter ended March 31, 2021, and provided an update on its clinical and preclinical programs.
"We are building momentum and executing on our plans to demonstrate the clinical potential of our Synthetic Biotic platform in 2021," said Aoife Brennan, M.B. Ch.B., Synlogic's President and Chief Executive Officer. "With proof of mechanism established in our two lead metabolic programs and a strengthened balance sheet, we are well positioned to deliver proof of concept readouts for both SYNB1618 in Phenylketonuria (PKU) and SYNB8802 in Enteric Hyperoxaluria later this year."
The Metabolic Portfolio:
Continued development of Synthetic Biotic™ medicines for the treatment of PKU.
Enrollment of the SynPheny-1 Phase 2 trial is on track with data expected in the second half of 2021. SynPheny-1 is designed to evaluate plasma phenylalanine (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® (sapropterin dihydrochloride) or PALYNZIQ® (pegvaliase-pqpz).
Data on the solid oral formulation of SYNB1618 was presented at the American College of Medical Genetics meeting in April 2021.
Continued development of SYNB1934, an evolved Synthetic Biotic medicine in the PKU portfolio, which may provide increased Phe lowering efficacy, lower dosing, or both, relative to SYNB1618. SYNB1934 is progressing through IND enabling studies.
SYNB1618 and SYNB1934 are orally administered Synthetic Biotic medicines being developed as potential treatments for PKU. They are intended to address the needs of patients of all age groups through the consumption of Phe in the gastrointestinal (GI) tract, which has the potential to lower blood Phe levels and enable the consumption of more natural protein in the diet.
Demonstration of proof of mechanism of SYNB8802, a Synthetic Biotic medicine being developed for the treatment of EntericHyperoxaluria.
In an ongoing Phase 1 study, SYNB8802 demonstrated safety and urinary oxalate lowering in healthy volunteers consuming a high oxalate diet.
Urinary oxalate lowering by SYNB8802 was dose-dependent. The 3e11 dose was chosen for further evaluation in the second part of the Phase 1 study in patients with Enteric Hyperoxaluria. This dose was well-tolerated and resulted in a 28.6% (90% CI: -42.4 to -11.6) reduction in urinary oxalate as measured by a change from baseline compared to placebo.
The second part of the Phase 1 study is continuing with the evaluation of SYNB8802 in patients with Enteric Hyperoxaluria secondary to Roux-en-Y gastric bypass surgery. Data from the second part of the study is anticipated in the second half of 2021.
SYNB8802 is an orally administered Synthetic Biotic medicine being developed as a potential treatment for Enteric Hyperoxaluria. Enteric Hyperoxaluria results in dangerously high urinary oxalate levels causing progressive kidney damage, kidney stone formation, and nephrocalcinosis. Enteric Hyperoxaluria has no approved treatment options. SYNB8802 is designed to consume oxalate in the GI tract to prevent the increased absorption of oxalate in patients with Enteric Hyperoxaluria.
The Immunomodulation Portfolio:
Progressionof SYNB1891 in combination arm dosing with PDL1 checkpoint inhibitor in an ongoing Phase 1 clinical study in patients with advanced solid tumors or lymphoma.
SYNB1891 is currently being evaluated in a Phase 1 study that has two parts:
Part A is a monotherapy arm that has enrolled six dose cohorts to date. The maximum tolerated dose has not been reached and dose escalation continues.
Part B is a combination arm and dosing has been completed in two cohorts to date with SYNB1891 and the PD-L1 checkpoint inhibitor atezolizumab to establish a recommended Phase 2 dose for the combination regimen.
Data from this study was presented at the American Association of Cancer Research meeting in April 2021.
SYNB1891 is an intratumorally administered Synthetic Biotic medicine engineered to act as a dual innate and adaptive immune activator. Data from both arms of the Phase 1 study will continue to be reported over the course of 2021, with mature combination therapy data expected by the end of the year.
Synlogic strengthens Balance Sheet.
On April 20th, subsequent to the end of the first quarter, Synlogic completed an underwritten public offering of 11.5 million shares. Net proceeds from the offering were $32.6 million, bringing Synlogic's cash balance to approximately $127 million.
Synlogic advances strategic partnerships and expands manufacturing capabilities.
Synlogic plans to expand its manufacturing footprint by more than 50% to support continued advancement of its pipeline and late-phase development of its lead metabolic programs.
Synlogic will invest to expand fermentation and lyophilization capacity to support scale up efforts, enabling potential late stage development of SYNB1618 and SYNB8802.
Construction and build out anticipated to take place in the second half of 2021.
Synlogic and the MIT Voigt Lab are collaborating with the Air Force Research Laboratory (AFRL) and the Department of Defense (DoD) to engineer novel investigational medicines to address battle fatigue.
Synlogic and Ginkgo Bioworks continue to advance their long-term strategic platform collaboration that provides expanded synthetic biology capabilities to Synlogic with multiple undisclosed metabolic programs now in preclinical stages of development.
First Quarter 2021Financial Results
As of March 31, 2021, Synlogic had cash, cash equivalents and short-term investments of $94.4 million.
For the three months ended March 31, 2021, Synlogic reported a consolidated net loss of $15.0 million, or $0.36 per share, compared to a consolidated net loss of $15.8 million, or $0.46 per share, for the corresponding period in 2020.
Research and development expenses were $11.2 million for the three months ended March 31, 2021 compared to $12.7 million for the corresponding period in 2020.
General and administrative expenses for the three months ended March 31, 2021 were $3.9 million compared to $3.8 million for the corresponding period in 2020.
There was no revenue for the three months ended March 31, 2021 compared to $0.1 million for the corresponding period in 2020. Revenue for the prior period was associated with Synlogic's collaboration with AbbVie to develop Synthetic Biotic medicines for the treatment of Inflammatory Bowel Disease which was terminated in May 2020.
Based upon its current operating plan, balance sheet as of March 31st, 2021 and proceeds from the recent public offering in April 2021, Synlogic expects to have sufficient cash to be able to fund the base operating plan into the second half of 2023.
