Dose Escalation Study to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of REMD-477 in Subjects With Type 2 Diabetes Mellitus
Study Details
Study Description
Brief Summary
This is a randomized, placebo-controlled, double-blind, dose escalation study to evaluate safety, tolerability, PK and PD of single and repeated SC doses of REMD-477 in Type 2 diabetic subjects. The study will be conducted at multiple sites in the United States and will enroll approximately 102 subjects with Type 2 diabetes who are either treatment-naïve, controlled with diet and exercise or treated with oral antidiabetic medications.

Phase 1/Phase 2 |
Detailed Description
The study will consist of three parts: Part A - Dose Escalation, Part B - Adaptive Dose Cohort, and Part C - REMD-477 in Combination with Metformin. Part A includes 5 cohorts that will be enrolled and dosed sequentially at escalating doses. Each cohort will consist of 12 subjects randomized in a 3:1 (active: placebo) fashion. Part B includes a single dose cohort that will enroll 12 subjects (9 on active treatment and 3 on placebo) with dose level and frequency determined by a Dose Level Review Meeting (DLRM)Committee. Part C includes 2 cohorts of T2DM patients currently treated with metformin alone, and each cohort will consist of 15 subjects (10 on active treatment and 3 on placebo).

Outcome Measures
Primary Outcome Measures
- Number of treatment emergent adverse events per subject, including changes in vital signs, physical and neurological examinations, laboratory safety tests and ECGs [141 Days]
Secondary Outcome Measures
- Pharmacokinetic (PK) profile (parameters including maximum observed concentration (Cmax), area under the curve (AUC) serum-concentration, clearance, and half-life (t1/2) after single and repeated SC doses. [141 Days]
- Changes in fasting glucose and insulin levels following single and repeated SC doses of REMD-477. [141 Days]
- Changes in glucose and insulin AUC following a Mixed Meal Tolerance Test. [Day 29, Day 57 and Day 85]
- Incidence of REMD-477 neutralizing and non-neutralizing antibodies [141 Days]
- Incidence of elevated alanine transaminase (ALT) or aspartate transaminase (AST) values >3x the upper limit of normal with concomitant >2x increases in alkaline phosphatase (ALP) and/or >2x total bilirubin. [141 Days]
- Incidence and severity of elevated amylase and lipase values at >2.5x ULN after study treatment [141 Days]
- Geometric mean ratio to baseline over time of AST, ALT, ALP and total bilirubin. [141]
