Type 2 Diabetes Mellitus (T2DM)
Conditions
Brief summary
This is a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of 24 once-weekly subcutaneous doses of PB-119 to subjects with type 2 diabetes mellitus (T2DM) not well-controlled by metformin monotherapy.
Detailed description
This is a phase 3 multicenter, randomized, double-blind, placebo-controlled, parallel dose cohort study to evaluate the efficacy and safety of PB-119 to patients with T2DM not well-controlled by metformin monotherapy. Patients will be assessed for eligibility over a 2 week screening period prior to a 4-week run-in period,a 24-week double-blind treatment period and a 28-week open-label treatment period. The eligible patients will be randomized to PB-119 or placebo cohort at a 1:1 ratio for the first 24-week. Patients in PB-119 group will subsequently be given active drug and patients in placebo group will take placebo, all patients in two groups will remain metformin background therapy. In the 28-week open-label period, all patients will be administered active drugs. After that, there will be a 4-week follow-up period; All randomized patients will be taken blood samples for the pharmacokinetic (PK) analysis.
Interventions
PB-119 is an investigational pegylated human glucagon-like peptide-1 (GLP-1) receptor agonist. The dosing regimen is 150μg once every week as subcutaneous administration. Patients in PB-119 group will be administered the active drugs for 52 weeks (24+28).
PB-119 matched placebo will be used once every week as subcutaneous administration to placebo group for 24 weeks.
