Weekly insulin shot could replace daily injections for type 2 diabetes
NCT ID NCT06767761
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new insulin (GZR4) given just once a week, compared to a standard daily insulin (glargine), in 580 adults with type 2 diabetes who already use mealtime insulin. The goal is to see if the weekly shot controls blood sugar as well or better, with fewer injections and similar safety. Participants continue their usual mealtime insulin and other diabetes medications.

Or 1 or 2 times daily of a premixed insulin analogue or dual insulin analogue. Exclusion Criteria: * A history of allergy to drugs with two or more mechanisms of action in the past, or known allergies, hypersensitivity, or intolerance to the investigational medicinal product or its excipients (glycerol, phenol, m-cresol, zinc acetate dihydrate, sodium chloride, citric acid monohydrate, or zinc chloride). * Subjects who are pregnant, lactating or planning to become pregnant during the study at screening. * Participated in any drug clinical study (received non-placebo medication during the study) within a recent period of time (90 days or 5 half-lives of the previous investigational medicinal product, whichever is longer), or plans to participate in another clinical study before completing all scheduled assessments in this clinical study. * Underwent invasive cardiovascular or cerebrovascular procedures within 180 days before screening; or experienced acute heart failure, myocardial infarction, stroke, or hospitalization due to angina unstable, transient ischaemic attack, or other acute cardiovascular events within 180 days before screening; or have a history of chronic cardiac failure classified as New York Heart Association Class III or IV at screening; or plan to undergo coronary, carotid, or peripheral arterial revascularisation procedures during the study; or have clinically significant abnormalities on the electrocardiogram (ECG) that require treatment at screening (such as second-degree type II or third-degree atrioventricular block, ventricular fibrillation, ventricular flutter, atrial fibrillation, atrial flutter, Wolff-Parkinson-White syndrome, etc.). * History of malignant tumors before screening (excluding adequately treated or resected non-metastatic basal or squamous cell skin cancer, cervical carcinoma in situ, or prostate cancer in situ) or the presence of underlying malignancy at screening. * The patient with SBP ≥ 160 mmHg or DBP ≥ 100 mmHg during screening. * Subjects who are unable to comply with the requirements of this protocol as judged by the investigator, or have any other conditions that the investigator considers inappropriate to participate in this study.
