A Single-Center, Open-Label, Single Ascending Dose Study of Exenatide Circular RNA-Lipid Nanoparticle Injection (CR059) in Chinese Subjects With Type 2 Diabetes Mellitus

Recruiting now · Early Phase 1

Conditions studied: T2DM

In brief

Primary Objectives: •To evaluate the safety and tolerability of a single dose of Exenatide Circular RNA-Lipid Nanoparticle Injection（CR059）in Chinese subjects with T2DM. Secondary Objectives: * To characterize the pharmacokinetic (PK) profile of a single dose of Exenatide Circular RNA-Lipid Nanoparticle Injection（CR059） in Chinese subjects with T2DM; * To characterize the pharmacodynamic (PD) profile of a single dose of Exenatide Circular RNA-Lipid Nanoparticle Injection（ CR059） in Chinese subjects with T2DM; * To evaluate the immunogenicity of a single dose of Exenatide Circular RNA-Lipid Nanoparticle Injection（ CR059） in Chinese subjects with T2DM; Participants : Diagnosed with T2DM for at least 3 months but less than 5 years, according to the Chinese Diabetes Society's diagnostic criteria

Able to complete the trial according to the protocol requirements.

You may not qualify if…

Diagnosis of type 1 diabetes, diabetes due to pancreatic injury, or specific types of diabetes due to other diseases (e.g., acromegaly or Cushing's syndrome).
History of acute diabetic complications, such as ketoacidosis or hyperosmolar coma, within 6 months before screening.
Presence of severe chronic diabetic complications (e.g., proliferative diabetic retinopathy, severe diabetic neuropathy, diabetic foot, etc.) within 6 months before screening, deemed by the investigator as unsuitable for participation.
Allergic constitution (allergy to ≥2 types of drugs or foods) or keloid tendency, or clear history of drug allergy, or investigator suspects potential allergy to the investigational product or its components or similar drugs.
Fasting plasma glucose <3.9 mmol/L at screening or before enrollment, and/or history of ≥2 episodes of severe hypoglycemia or recurrent symptomatic hypoglycemia within 6 months before screening.
History or presence of Cushing's syndrome, polycystic ovary syndrome, or other hereditary endocrine diseases, or obesity secondary to factors such as hormones.
Use of weight-control medications or weight-loss surgery within 3 months before screening, or weight fluctuation exceeding 5% within 3 months.
Clinically significant abnormal TSH, FT3, or FT4 at screening, or previous diagnosis of thyroid dysfunction, deemed unsuitable by the investigator.
Personal or family history of multiple endocrine neoplasia type 2; personal or family history of medullary thyroid carcinoma; or thyroid nodules classified as C-TIRADS category 4 or higher on ultrasound.
History or presence of malignant tumors (except cured basal cell carcinoma or cervical carcinoma in situ).
History of thrombotic diseases (e.g., deep vein thrombosis, pulmonary embolism, stroke), known bleeding diathesis or coagulation dysfunction, major thrombotic event within 6 months, or any coagulation parameter ≥1.5x ULN, or clinically significant abnormal coagulation function deemed unsuitable by the investigator.
