  • Part B of the study is continuing to evaluate of SYNB8802 in patients with enteric hyperoxaluria secondary to Roux-en-Y gastric bypass surgery, with data expected next year.
• Further data on SYNB8802 and enteric hyperoxaluria were presented at the American Urological Association 2021 Annual Meeting and the American Society of Nephrology Kidney Week 2021, including real-world evidence demonstrating a relationship between higher urinary oxalate levels and increased incidence of chronic kidney disease.

Homocystinuria (HCU): Synlogic and Ginkgo announced that SYNB1353 for the treatment of homocystinuria has been advanced into IND-enabling studies, with entry into the clinic expected in 2022.
