About this trial
This study is testing VV-14300 in adults with long-standing type 1 diabetes (T1D) whose blood sugar is not well controlled despite using an automated insulin delivery (AID) system. VV-14300 is an investigational gene therapy that is injected into muscle and is designed to help remove excess sugar from the blood.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Able to provide signed informed consent.
18 to 65 years of age (inclusive) at Screening.
Body mass index (BMI) of 20.0 to <30.0 kg/m².
Clinical diagnosis of Type 1 Diabetes for at least 5 years prior to Screening, currently managed with an Automated Insulin Delivery (AID) system for at least 3 months prior to Screening.
Disqualifiers
Type 2 diabetes or other condition requiring exogenous insulin that is not due to autoimmunity, or when insulin delivery is not managed through an AID system.
Diabetic complications (e.g., severe/proliferative retinopathy or neuropathy) or a clinically significant medical, cognitive, or psychiatric condition that, in the Investigator's opinion, poses additional risk or would make consistent study follow-up unlikely.
Recurrent diabetic ketoacidosis (2 or more events in the 12 months prior to Screening).
Pregnant or breastfeeding.
