Synlogic Presents at Global PKU Patient Meeting

CAMBRIDGE, Mass., Sept. 10, 2021 /PRNewswire/ -- Synlogic, Inc. (Nasdaq: SYBX), a clinical stage company bringing the transformative potential of synthetic biology to medicine, today presented on the development of investigational Synthetic Biotic medicines for the treatment of Phenylketonuria (PKU) at the Global PKU Patient Meeting, being held virtually September 10-11th, 2021.

The presentation, "Synthetic Biotic Medicines for the Treatment of PKU," was delivered by Dr. Marja Puurunen, M.D., Ph.D., Synlogic's Senior Medical Director and Head of Metabolic Programs, and included an overview of the SYNB1618 development program.

In addition, Synlogic presented findings from a survey of adult PKU patients and the caregivers of pediatric PKU patients on their experience with the low phenylalanine diet which remains the primary treatment for PKU. Findings from the survey include:
  • Two-thirds of adult and one-third of pediatric PKU patients do not have Phe levels within the target range, despite a restrictive low phenylalanine diet and treatment with currently available therapies.
  • Greater than 90% of patients and 95% of pediatric caregivers would like to increase the amount of natural protein in their diet.
  • More than 50% of adult respondents and more than 80% of pediatric caregiver respondents found 2-3 grams of additional natural protein per day "meaningful."
    • One slice of bread or one medium sized potato contains 2-3 grams of natural protein.

The survey was conducted through partnerships with the National PKU Alliance (NPKUA) of the U.S. and the Canadian PKU and Allied Disorders Inc (CanPKU). Complete survey results will be presented at a future medical meeting or in publication.

About PKU
Phenylketonuria (PKU) is an inherited metabolic disease that manifests at birth and is marked by an inability to break down phenylalanine (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 SYNB1618
SYNB1618 is an investigational oral drug for the treatment of Phenylketonuria (PKU) composed of an engineered Synthetic Biotic designed to lower plasma phenylalanine (Phe) levels by consuming Phe in the GI tract. A solid oral lyophilized formulation of SYNB1618 was found to be safe and well-tolerated, and consumes Phe in the GI tract of healthy volunteers. Synlogic has initiated a Phase 2 study in PKU patients (NCT04534842).
