研究概览
详细说明
This Phase 2 study was designed to evaluate the efficacy and safety of PDA-002, a human placenta-derived cell therapy, administered via intramuscular injection in subjects with diabetic foot ulcers (DFU). The study included subjects with and without peripheral arterial disease (PAD), reflecting a broader DFU population.
Subjects were randomized in a parallel-group design to receive PDA-002 at one of three dose levels (3 × 10^6, 10 × 10^6, or 30 × 10^6 cells) or matching placebo, administered on Study Days 1 and 8. Randomization was stratified by PAD status.
The primary objective was to assess efficacy in terms of wound healing outcomes, with secondary objectives evaluating vascular parameters such as ankle-brachial index (ABI), toe-brachial index (TBI), and transcutaneous oxygen pressure (TcPO2), as well as overall safety.
The study was terminated early due to a business decision; however, subjects were followed according to protocol-defined follow-up schedules.
