Study of Human Placenta-derived Cells (PDA002) to Evaluate the Safety and Effectiveness in Subjects With PAD and DFU
A Phase 1, Multicenter, Open-Label, Dose-escalation Study to Evaluate the Safety and Efficacy of Intramuscular Injection of Human Placenta-derived Cells (PDA-002) in Subjects With Peripheral Arterial Disease and Diabetic Foot Ulcer

This clinical study is being conducted to assess the safety and determine the maximum tolerated dose (MTD) of PDA-002 [human placenta-derived cells] administered into the lower leg muscles of subjects with peripheral arterial disease and diabetic foot ulcers. It will look to see if PDA-002 helps reduce some of the symptoms of PAD and/or improves ulcer healing. This study will also help to find the best dose of PDA-002 to use in future studies.

The goal of this study is to determine a safe dose of PDA-002 [human placenta-derived cells] for further study. This is a dose-escalation study where each of four dose levels will enroll three to six subjects. Doses will be range from 3 million up to 100 million cells. If one dose is considered safe after all treated subjects have been evaluated and reviewed, then the next group of subjects will be enrolled to receive the next higher dose. This will continue until either the highest dose is reached, until at least 2 subjects at a dose level have ≥ Grade 2 allergic reaction that is suspected to be related to PDA-002 or 2 or more subjects at a dose level experience an unexpected, treatment-related serious adverse event or dose limiting toxicity within 14 days following the initial dose of PDA-002. This is an open-label study where all subjects will be taking the study drug and all study personnel will know the dose each subject receives.

March 2016   (final data collection date for primary outcome measure)

Inclusion Criteria:

  • Subjects must satisfy the following criteria to be enrolled in the study:

    3. Able to adhere to the study visit schedule and other protocol requirements.
    4. Diabetes mellitus type 2
    5. Ischemic or neuro-ischemic diabetic foot ulcer with severity of Grade 1 (full thickness only) or Grade 2 on the Wagner Grading Scale (Appendix A) of greater than one month duration which has not adequately responded to conventional ulcer therapy.
    6. Peripheral arterial disease with ankle-brachial index > 0.6 and ≤ 0.9 or toe-brachial index > 0.35 and ≤ 0.7.
    7. No planned revascularization or amputation over the next 3 months after Screening visit, in the opinion of the Investigator.
    8. Not a candidate for peripheral artery percutaneous or surgical revascularization.
    9. Screening should not begin until at least 2 weeks after a failed reperfusion intervention and at least 2 months after a successful mechanical intervention.
    10. Subject can have stable angina, (Canadian Cardiovascular Society (CCS) Class I-II angina (Appendix H).
    11. Subjects should be receiving appropriate medical therapy for hypertension and diabetes.
    12. Subject must be a non-tobacco user defined as someone who has not used tobacco/nicotine patch for ≥ 3 months and must agree to remain tobacco/nicotine free for the duration of the study.

In addition, sexually active FCBP must agree to use 2 of the following adequate forms of contraception methods simultaneously such as: oral, injectable, or implantable hormonal contraception; tubal ligation; intrauterine device [IUD]; barrier contraceptive with spermicide or vasectomized partner for the duration of the study and the follow-up period.
