Detailed Description

The proposed study, NM8074-C3G-101, will enroll a planned number of 18 patients, with the potential to enroll more patients. There will be 3 cohorts with 6 patients each dosed at 5, 10, or 20 mg/kg depending on which cohort they are assigned to. Enrollment in the subsequent higher dose level cohort will occur after the previous cohort has been evaluated for safety.
