A Clinical Efficacy and Safety Study of Insulin Glargine U300 in Chinese Adult Patients With Uncontrolled Type 2 Diabetes Mellitus With a 3-month Extension Period

Maximum study duration per participant will be approximately 37 weeks per patient: up to 1 week screening period, 24 weeks insulin glargine U300 treatment period and 12 weeks observational extension period.

Inclusion criteria

• Adult patients (age≥18 years) who diagnosed with type 2 diabetes
• Patients who should initiate Insulin glargine U300 treatment following local label and guideline at investigator's discretion, including:

• insulin naive patients (no current or previous insulin used during the last year prior to screening except for a maximum 10 days in relation to acute illness or surgery, etc.) uncontrolled (HbA1c between 7.5% and 11.0%) at screening visit on stable dose treatment with ≤ 2 OADs (metformin, sulfonylurea, thiazolidinedione, DPP-4 inhibitor, SGLT-2 inhibitor, glinide, α-glucosidase inhibitor) within 8 weeks prior to screening, at least one of which must be on maximum tolerated dose, or
• patients uncontrolled (HbA1c between 7.5% and 11.0%) at screening visit with other basal insulin, or
• patients controlled with other basal insulin but experienced frequent hypoglycemia or with increased hypoglycemia risk at investigator's discretion
• Patients who treated with basal insulin must have a stable dose of antidiabetic drugs (dose change no more than ±20% vs. the dose on screening visit for basal insulin) within 8 weeks prior to screening

Exclusion criteria

• Any clinically significant abnormality identified on physical examination, laboratory tests, or vital signs at the time of screening, or at baseline, or any major systemic disease resulting in short life expectancy that in the opinion of the Investigator would restrict or limit the patient's successful participation for the duration of the study
• Use of any product containing short or rapid acting insulin in the last 3 months prior to screening (unless used for ≤10 days in relation to hospitalization or an acute illness)
• Use of oral anti-diabetic drugs other than those allowed and listed in the inclusion criteria, Glucagon-like peptide-1 (GLP-1) receptor agonists, or any investigational agent (drug, biologic, device) within 3 months prior to screening visit
• Use of systemic glucocorticoids (excluding topical application or inhaled forms) for two weeks or more within 8 weeks prior to the time of screening
• Known hypersensitivity / intolerance to insulin glargine or any of its excipients
• Pregnant or lactating women
• Women of childbearing potential with no effective contraceptive method
• Participation in another clinical trial
