Phase 1/2a, Randomized, Double-Blind, Placebo-Controlled, Study to Assess Safety, Tolerability, PK and PD Response of PB1023 Injection Following Single and Multiple SQ Doses in Adults With Type 2 Diabetes Mellitus

Phase 1
Completed
Conditions
Diabetes Mellitus, Type 2
Interventions
Drug: Single Subcutaneous Dose (Part A) of PB1023 or Placebo (0.9% NaCl)
Drug: Multiple (Four Weekly) Subcutaneous Injections (Part B) of PB1023 or Placebo (0.9% NaCl)
Registration Number
NCT01236404
Lead Sponsor
PhaseBio Pharmaceuticals Inc.
Brief Summary

Primary objective:

To evaluate the safety and tolerability of single and multiple ascending doses of PB1023 administered as a subcutaneous (SC) injection in adult subjects with T2DM.

Secondary objectives:

1. To characterize the pharmacokinetic profile of PB1023 after single and multiple ascending doses of PB1023.

2. To assess the pharmacodynamic response of various single and multiple doses of PB1023 (daily fasting plasma glucose, and serial glucose, c-peptide and insulin levels in response to a liquid Mixed Meal Tolerance Test (MMTT).

Primary Outcome Measures
NameTimeMethod
Safety/TolerabilityScreening to Final Visit (up to approximately 10 weeks for SAD and 14 weeks for MAD)

Safety will be evaluated by analyses of incidence of adverse events of interest (possibly related to the class of drug) and other adverse events. Vital signs, ECGs and safety laboratory parameters will also be presented.

Secondary Outcome Measures
NameTimeMethod
Pharmacokinetic ProfileSAD: Pre-dose, 1, 4, 8, and 12 hours post-dose and Day 1, 2, 3, 5, 7, 10, 14, 21 and 28. MAD: Pre-dose, 1, 4, 8, and 12 hours post-dose and Day 1, 2, 3, 5, pre-dose Days 7, 14 and 21 and at 1, 4, 8, and 12 hours post-dose and Day 22, 23, 26, 28, 35, 42,

To characterize the PK profile of PB1023 after single and multiple ascending doses of PB1023. The following parameters will be evaluated: t1/2, AUC(inf), AUC(0-t), Tmax, Cmax, Elimination Rate Constant, Clearance and Distribution.

Pharmacodynamic ResponseFasting plasma glucose collected the day before dosing and with PK samples, excluding day of dosing. SAD MMTT to occur on day 0 and 2, MAD MMTT to occur on Day 0 and 22 with continuous glucose monitoring on Day -8/-7 to Day 0 and on Day 21 to Day 28.

To assess the pharmacodynamic response of various single and multiple doses of PB1023 (daily fasting plasma glucose and serial glucose (and continuous monitoring as defined in time frame), c-peptide and insulin levels in response to a liquid mixed meal tolerance test (MMTT) pre and post dose) on subjects washed off their baseline oral antihyperglycemic agents.
