Phase 2a Study of ZT-01 Injections to Reduce Night-time Low Blood Sugar in Adults with Type 1 Diabetes

What this Trial Is About

Researchers are studying the effects of the drug ZT-01 on nighttime low blood sugar hypoglycemia in adults with type 1 diabetes who experience low blood sugars at night. The study aims to find out if ZT-01 can reduce the number of nighttime hypoglycemia episodes and how it affects blood sugar levels. The safety of ZT-01 will also be evaluated during this phase 2a trial sponsored by Zucara Therapeutics Inc. Participants will receive both placebo and ZT-01 at one of three dose levels 7 mg, 15 mg, or 22 mg, injected under the skin daily for 28 days each. The study uses a randomized, double-blind, crossover design, so participants will receive ZT-01 during one period and placebo during another, without knowing which they are receiving. They will wear a continuous glucose monitor CGM provided by the study during treatment periods and continue their usual blood sugar monitoring and insulin use. During the approximately 16-week study, participants will have up to 6 visits and 2 phone calls. They will provide blood and urine samples to assess eligibility and effects of treatment, have blood pressure and temperature checked at visits, and receive ECGs at 4 visits to monitor heart activity. Some participants may join a sub-study requiring overnight stays for blood level tests of ZT-01 and glucagon. Participants will complete daily diaries and upload CGM data to a study phone for ongoing monitoring. The main outcome measured is the number of nighttime hypoglycemia episodes during each 28-day treatment period.
