- Brief Summary
A phase 2, multicenter study to evaluate the efficacy and safety of twelve once weekly subcutaneous doses of PB-119 to patients with type 2 diabetes mellitus (T2DM) not well-controlled by metformin mono therapy.
- Detailed Description
This is a multicenter, randomized, double-blind, placebo-controlled, parallel dose cohort, multiple dose study to evaluate the efficacy, safety, and tolerability of different doses 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 and a 12-week double-blind treatment period.A phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel dose cohort study to evaluate the efficacy and safety of twelve once weekly subcutaneous doses of PB-119 to patients with type 2 diabetes mellitus (T2DM) not well-controlled by metformin monotherapy The eligible patients will be randomized to 1 of 3 dose cohorts (A, B, or C). Each patient will subsequently be randomized within the designated cohort to 1) active drug or placebo at a 3:1 active drug:placebo ratio and 2) exclusion from or inclusion in the pharmacokinetic (PK) blood sample collection subgroup at a 3:1 excluded:included ratio

- Patients in whom T2DM has been diagnosed according to 2018 American Diabetes Association T2DM diagnostic criteria, have made lifestyle modifications (ie, diet and exercise) for at least 3 months prior to Screening, and have been taking metformin for at least 3 months before Screening with a stable dosage for at least 8 weeks (stable dosage is defined as metformin dosage ≥1500 mg/day or maximum tolerated dose).
- Males and/or females between the ages of ≥18 and ≤70 years at Screening
- HbA1c ≥7.5% and ≤11% at Screening and at Week -1, Visit 3.1;
- FPG ≥126 and ≤240 mg/dL (≥7.0 and ≤13.3 mmol/L) at Screening and at Week -1, Visit 3.1;
- Body mass index (BMI) ≥18.5 and ≤40.0 kg/m2 at Screening, with inclusion of patients with BMIs at the lower end of the range enrolled into the study to enable comparisons across BMI range;
-
Medical history or current diagnosis of:
- Type 1 diabetes mellitus, diabetes caused by pancreas injury or by other diseases (like acromegaly or Cushing syndrome);
- Diabetes acute complication, like ketoacidosis or hyperosmolar coma;
- Diagnosed proliferative retinopathy;
- 3 instances of severe hypoglycemia (events during which the patient required the assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions; episodes may be associated with sufficient neuroglycopenia to have induced seizure or coma) in the 6 months prior to Screening;
- Significant vascular disease;
-
Current/ongoing diagnosis of any type of malignant tumor or evidence of recurrence in the 6 months prior to Screening (patients who have been stable for ≥6 months or those who have had basal or squamous cell skin cancers removed and have no evidence of recurrence will not be excluded). Patients with a medical history of any other type of cancer in the last 5 years prior to Screening will be excluded;
-
Severe cardiovascular diseases occurring within 6 months prior to Screening (eg, congestive heart disease, myocardial infarction, acute coronary syndrome, apoplexy, transient ischemic attack);
