Synlogic Inc SYBX

CAMBRIDGE, Mass., Aug. 12, 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 second quarter ended June 30, 2021, and provided an update on its clinical and preclinical programs.

"We are executing across our co-lead metabolic programs and advancing towards proof of concept readouts of our Synthetic Biotic™ medicines for the treatment of Phenylketonuria and Enteric Hyperoxaluria," said Aoife Brennan, M.B. Ch.B., Synlogic's President and Chief Executive Officer. "With a next-generation strain in a Phase 1 study for the treatment of Phenylketonuria, a strategic collaboration in place to expand our IBD pipeline and an advancing pre-clinical pipeline of metabolic disease programs, we have a robust set of potential therapies that could provide meaningful benefit to patients. We look forward to communicating results and next steps over the coming months."  

Quarter Highlights

The Metabolic Portfolio:

Proof of concept data of SYNB1618 for the treatment of Phenylketonuria (PKU) anticipated in second half of 2021, Phase 1 study of SYNB1934 initiated.

• The SynPheny-1 Phase 2 trial of SYNB1618 continues to progress.
• 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.
• In July, the Company initiated a Phase 1 study of SYNB1934, a next-generation strain designed for the treatment of PKU, to evaluate safety, tolerability and head-to-head comparison of Phe-consumption biomarkers between SYNB1934 and SYNB1618.
• SYNB1934, an evolved strain of SYNB1618 in the PKU portfolio, has the potential to provide increased benefit to patients living with PKU.
• Preclinical in vivo and in vitro studies demonstrated a greater than 2-fold improvement in the ability of SYNB1934 to consume and break down Phe compared to SYNB1618.
• Papers published in the journals Nature Metabolism and Communications Biology detail findings from a first-in-human study of SYNB1618 and the development of a mechanistic model to predict the function of Synthetic Biotic medicines in healthy volunteers and PKU patients.
• Data from the first-in-human study of SYNB1618 showed dose-responsive, non-saturated increases in gastrointestinal consumption of Phe by SYNB1618.
• These data add to the growing body of scientific research demonstrating the therapeutic potential of Synthetic Biotic medicines for the treatment of PKU.

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.

Proof of concept data of SYNB8802 for the treatment of Enteric Hyperoxaluria anticipated in second half of 2021.

• SYNB8802 demonstrated proof of mechanism in Part A of an ongoing Phase 1 trial, with evidence of urinary oxalate lowering in a Dietary Hyperoxaluria model in healthy volunteers given a high oxalate diet.
• Urinary oxalate lowering by SYNB8802 was robust and dose-dependent.
• The 3e11 dose is undergoing evaluation in Part B of the 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.
• Part B of the study is continuing with the evaluation of SYNB8802 in patients with Enteric Hyperoxaluria secondary to Roux-en-Y gastric bypass surgery.
• Data on the development of SYNB8802 was presented at the Synthetic Biology: Engineering, Evolution & Design (SEED) conference in June 2021.

SYNB8802 is an orally administered Synthetic Biotic medicine being developed as a potential treatment for Enteric Hyperoxaluria. SYNB8802 is designed to consume oxalate in the GI tract to prevent the increased absorption of oxalate in Enteric Hyperoxaluria patients.

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. Approximately 100,000 patients in the US suffer from chronic and recurrent kidney stones as a result of severe Enteric Hyperoxaluria.

The Immunomodulation Portfolio:

Progression of SYNB1891 in combination arm dosing with PD-L1 checkpoint inhibitor in Phase 1 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. Part B is a combination arm with SYNB1891 and the PD-L1 checkpoint inhibitor atezolizumab that has enrolled two dose cohorts to date.
• The study is ongoing. Mature combination therapy data is expected by the end of the year.

SYNB1891 is an investigational drug for the intra-tumoral treatment of solid tumors and lymphoma, composed of an engineered Synthetic Biotic strain of E. coli Nissle that produces cyclic di-AMP (CDA), a stimulator of the STING (STimulator of INterferon Genes) pathway.

Advancement of preclinical programs in Inflammatory Bowel Disease.

• In June, Synlogic and Roche entered into a research collaboration agreement for the discovery of a novel Synthetic Biotic medicine for the treatment of inflammatory bowel disease (IBD). Under the terms of the agreement, Synlogic and Roche will collaborate to develop a Synthetic Biotic medicine addressing an undisclosed novel target in IBD.
• Data on novel Synthetic Biotic approaches for the treatment of IBD was presented at Digestive Disease Week (DDW) in May 2021.

Corporate Update:

Synlogic strengthens Balance Sheet and advances synthetic biology capabilities.

• In April, Synlogic completed an underwritten public offering of 11.5 million shares, resulting in net proceeds to Synlogic of approximately $32.6 million.
• 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. Additional information on these programs will be provided over the course of the year.
