Regimen Transition After Short-Term Intensive Insulin Therapy in Type 2 Diabetes
Regimen Transition After Short-Term Intensive Insulin Therapy in Type 2 Diabetes Mellitus Patients With Inadequate Glycemic Control on Oral Hypoglycemic Agents: A Multicenter, Open-Label, Randomized Controlled Study
Source: ClinicalTrials.gov · Last updated 6 Feb 2026
Brief summary (registry, in English)
Failure of oral antidiabetic drugs (OADs) is a frequent challenge in patients with type 2 diabetes mellitus (T2DM), and inadequate long-term glycemic control substantially increases the risk of diabetic complications. Short-term intensive insulin therapy (SIIT) is an established approach to mitigate glucotoxicity; however, the optimal strategy to sustain long-term glycemic benefits after SIIT in T2DM patients with OAD failure remains unclear. To address this gap, we designed a randomized controlled trial to evaluate subsequent treatment options, aiming to identify a simple and effective regimen for patients with poor glycemic control who undergo SIIT. A total of 324 eligible patients will be enrolled. After screening, previous antidiabetic regimens will be discontinued, and patients will be randomly assigned to the SIIT- iGlarLixi group (A), the SIIT-IDegAsp group (B), or the SIIT-iGlar group (C). All patients will be hospitalized for short-term insulin pump therapy, followed by 24 weeks of treatment: group A with insulin glargine/lixisenatide, group B with insulin degludec/aspart, and group C with insulin glargine U300 plus metformin. During the extension follow-up period, patients in all groups may either continue their assigned regimen or return to their original pre-study therapy. A total of 10 clinic visits are scheduled for each patient throughout the study. Primary endpoint is proportion of patients achieving glycosylated hemoglobin A1C \<7% at 24 weeks.Secondary endpoints include proportion of patients achieving glycosylated hemoglobin A1C \<6.5% at 24 weeks; differences in weight gain, hypoglycemic events among treatment groups, and differences in proportion of patients continuing the assigned regimen, glycemic control and body weight at the extension follow-up period.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Receipt within 3 months prior to screening of premixed insulin therapy and/or basal-bolus insulin therapy and/or basal insulin plus OAD therapy for ≥7 cumulative days; or receipt within 1 year prior to screening of intensive insulin therapy (insulin pump or multiple daily injections); or receipt within 3 months prior to screening of GLP-1 receptor agonists; or inability to tolerate protocol-specified doses.
- Use within 12 weeks prior to screening of medications affecting glycemic control for \>1 cumulative week, including oral/intravenous glucocorticoids, growth hormone, estrogen/progestins, high-dose diuretics, or antipsychotics. Exceptions: low-dose diuretics used for antihypertensive purposes (HCTZ \<25 mg/day, indapamide ≤1.5 mg/day) and physiological thyroid hormone replacement therapy.
Other illness
- Diagnosis of type 1 diabetes mellitus or other specific types of diabetes.
- Known hypersensitivity or intolerance to study medications.
- Uncontrolled endocrine disorders.
- History or family history of medullary thyroid carcinoma, or history of multiple endocrine neoplasia syndrome type 2 (MEN2).
- Psychiatric illness or communication disorders.
- Systemic infection, severe comorbid conditions, malignancy, or chronic diarrhea.
- Any other condition deemed unsuitable by investigators, including history of acute pancreatitis, rapidly progressing gallstones, or chronic cholecystitis.
Lab values
- Severe microvascular complications: proliferative diabetic retinopathy; albumin excretion rate (AER) \>300 mg/g or proteinuria \>0.5 g/day; uncontrolled painful diabetic neuropathy or significant autonomic neuropathy. Severe macrovascular complications: hospitalization for acute cerebrovascular accident, acute coronary syndrome, peripheral artery disease requiring intervention or amputation within the previous 12 months; unstable angina, myocardial infarction, uncontrolled arrhythmia, or severe heart failure (New York Heart Association \[NYHA\] class ≥III).
- Estimated creatinine clearance \<45 mL/min/1.73 m² (calculated by CKD-EPI formula); alanine aminotransferase ≥2.5 × upper limit of normal (ULN); or total bilirubin ≥1.5 × ULN.
- Hemoglobin \<100 g/L or requiring regular blood transfusions.
Other
- Acute diabetic complications (including diabetic ketoacidosis, hyperosmolar hyperglycemic state, or lactic acidosis).
- Persistent blood pressure \>180/110 mmHg, or uncontrolled above 160/110 mmHg within 1 week.
