About

SY-009 is a novel compound that inhibits sodium glucose cotransporter-1 (SGLT-1). The preclinical and phase 1 clinical trial data support to carry out phase II clinical trial in diabetes subjects.

Enrollment: 200 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
