Synlogic Announces Initiation of Phase 1 Study of SYNB1934, a Next-Generation Strain for the Treatment of Phenylketonuria (PKU)
Synlogic, Inc. (Nasdaq: SYBX) announced the initiation of a Phase 1 clinical trial for SYNB1934, a Synthetic Biotic medicine aimed at treating Phenylketonuria (PKU). This new candidate shows a more than 2-fold improvement in phenylalanine (Phe) breakdown compared to its predecessor, SYNB1618. The trial will evaluate the safety, tolerability, and Phe consumption activity of SYNB1934, with results expected by the end of 2021. Synlogic aims to support PKU patients by providing effective treatment options, particularly for those not benefiting from existing therapies.
- Initiation of Phase 1 clinical trial for SYNB1934, a potential new treatment for PKU.
- Demonstrated >2-fold improvement in Phe breakdown efficacy in preclinical studies.
- Plans to select one therapeutic strain for late-stage development based on trial outcomes.
- None.
CAMBRIDGE, Mass., July 15, 2021 /PRNewswire/ -- Synlogic, Inc. (Nasdaq: SYBX), a clinical stage company bringing the transformative potential of synthetic biology to medicine, today announced that it has initiated the Phase 1 clinical trial of SYNB1934, an investigational Synthetic Biotic™ medicine for the treatment of Phenylketonuria (PKU).
"We are delighted to have so quickly advanced SYNB1934 into the clinic, strengthening our PKU portfolio and our potential to provide a meaningful new therapeutic option for patients living with PKU," said Aoife Brennan, M.B. Ch.B., Synlogic's President and Chief Executive Officer. "We are on track to report results from our Phase 2 clinical trial of SYNB1618 in the second half of 2021 and look forward to providing additional updates as we advance our PKU portfolio."
"SYNB1618 and SYNB1934 are orally administered Synthetic Biotic medicines intended to address the needs of PKU patients of all age groups and genotypes through the consumption of Phe in the gastrointestinal tract," said Richard Riese, M.D., Synlogic's Chief Medical Officer. "Our orally available and fully reversible Synthetic Biotic medicines have the potential to lower blood Phe levels, and potentially enable the consumption of more natural dietary protein. We aspire to bring forward the most compelling medicine possible to meet the needs of the significant number of patients who do not benefit from, or do not tolerate, existing therapies."
SYNB1934 is a strain that has been evolved from SYNB1618, which is currently being evaluated in a Phase 2 clinical study. SYNB1934 has the potential to provide increased phenylalanine (Phe) lowering efficacy for 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, based on production of Phe metabolites.
The Phase 1 multiple ascending dose study of SYNB1934 will evaluate the safety, tolerability and Phe consumption activity of SYNB1934, including a head-to-head comparison with SYNB1618 in healthy volunteers using biomarkers of Phe consumption. Based on the data from the head-to-head comparison, as well as results of the ongoing Phase 2 study of SYNB1618 in patients with PKU, Synlogic plans to select one therapeutic strain for late stage development. Data from the Phase 1 study is expected by the end of 2021.
Data on the solid oral formulation of SYNB1618 was presented at the American College of Medical Genetics meeting in April 2021, and data on the development of SYNB1934 was presented at the Synthetic Biology: Engineering, Evolution & Design (SEED) conference in June 2021.

About PKU
Phenylketonuria (PKU) is an inherited metabolic disease that manifests at birth and is marked by an inability to break down 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.
