Plans to initiate Phase III study for PKU in the first half of 2023.

Market Positioning: Focused on severe PKU patients and those who are treatment-resistant, indicating strong market interest in new therapies.

4Challenges and Points of Concern

Enrollment Challenges: Potential difficulties in enrolling patients for the Symphony trial due to ongoing recovery from the pandemic, as noted by other companies in the PKU space.

Market Dynamics: Observations of slower recovery rates in treatment centers could impact expectations for market opportunity, although management remains optimistic about interest in new therapies.

Manufacturing and Regulatory Risks: While there is positive engagement with the FDA regarding CMC requirements, final agreements are pending, which could pose risks to timelines.

5Notable Q&A Insights

Enrollment Expectations: Management anticipates faster enrollment for Phase III compared to Phase II due to more sites and a less intensive study design.

Age and Efficacy: There are considerations for including pediatric patients in future studies, with an understanding that endpoints may need to be adjusted based on age-related differences in PKU management.

Gout Program: The potential impact of SYNB 2081 on endogenous uric acid production was discussed, with indications that the treatment could affect both dietary and systemic sources of uric acid. Overall, Synlogic is navigating a promising yet challenging landscape as it advances its clinical programs while managing financial and operational hurdles.
