Synlogic Receives Orphan Drug Designation for SYNB1618, a Synthetic Biotic Medicine for the Treatment of Phenylketonuria

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Synlogic (Nasdaq: SYBX), a clinical stage company applying synthetic biology to probiotics to develop novel living medicines, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation to SYNB1618, Synlogic's preclinical-stage drug candidate for the treatment of phenylketonuria (PKU) , an inborn error of metabolism (IEM) caused by a mutation in the gene that breaks down the amino acid phenylalanine (Phe). Phe accumulation in the blood and brain can lead to neurocognitive abnormalities and treatment currently requires severe dietary protein restriction.

SYNB1618, an orally administered medicine, is designed to complement the missing function in patients with PKU by providing alternative metabolic pathways to consume Phe. Synlogic plans to file an investigational new drug application (IND) with the FDA for SYNB1618 for the potential treatment of PKU in early 2018.

"We believe our Synthetic Biotic medicines could transform the treatment of PKU," said Aoife Brennan, M.B., B.Ch., Synlogic's chief medical officer. "Consequently, we were pleased to receive the FDA's orphan drug designation which validates our approach and represents an important step toward achieving our goal of bringing novel treatments to the patients and families affected by this challenging disease."

The FDA's Orphan Drug Program offers orphan status to drugs and biologics that are intended for the treatment of rare diseases affecting fewer than 200,000 people in the U.S. The designation provides development and commercial incentives for designated compounds and medicines, including eligibility for a seven-year period of market exclusivity in the U.S. after product approval, FDA assistance in clinical trial design and an exemption from FDA user fees.

About PKU
Phe is an essential amino acid that enters the body as a component of dietary protein and can be toxic if its levels accumulate in the blood and brain. PKU is caused by a defect in the gene encoding phenylalanine hydroxylase (PAH), a liver enzyme that metabolizes Phe. Current disease management of PKU involves strict dietary protein restriction with the consumption of Phe-free protein supplements. The only currently approved medication, Kuvan®,is indicated for a subgroup of patients and does not eliminate the need for ongoing dietary management. Life-long Phe control is challenging due to the highly restrictive nature of the diet and patients typically experience worsening neurological function depending on the severity of their genetic mutation and their treatment compliance. PKU is diagnosed at birth, and the National PKU Alliance estimates that there are currently 16,500 people living with the disorder in the U.S.

About Synthetic Biotic Medicines
Synlogic's innovative new class of Synthetic Biotic medicines leverages the tools and principles of synthetic biology to genetically engineer probiotic microbes to perform or deliver critical functions missing or damaged due to disease. The company's two lead programs target a group of rare metabolic diseases - inborn errors of metabolism (IEM). Patients with these diseases are born with a faulty gene, inhibiting the body's ability to break down commonly occurring by-products of digestion that then accumulate to toxic levels and cause serious health consequences. When delivered orally, these medicines can act from the gut to compensate for the dysfunctional metabolic pathway and have a systemic effect. Synthetic Biotic medicines are designed to clear toxic metabolites associated with specific metabolic diseases and have the potential to significantly improve symptoms of disease for affected patients.

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's initial pipeline includes Synthetic Biotic medicines for the treatment of rare genetic diseases, such as urea cycle disorders (UCD) and phenylketonuria (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 liver disease, inflammatory and immune disorders, and cancer. Synlogic is collaborating with AbbVie to develop Synthetic Biotic-based treatments for inflammatory bowel disease (IBD). For more information, please visit www.synlogictx.com.
