Study Details

Study Description

Brief Summary

The objective of the present study is to establish the safety and efficacy of Prochymal® following first acute myocardial infarction.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

The standard of care treatment for acute myocardial infarction (AMI) usually includes immediate perfusion, optimal pain relief, oxygen, aspirin or other anti-coagulants, Beta-Blockers, nitrates and Ace-inhibitors. However, because salvaging the viable myocardium is dependent on early reperfusion, only a minority of participants will reach the hospital within the time-window for myocardial rescue. Thus, even if the participant manages their tobacco use, hypertension, lipid levels, diabetes, weight and exercise, many participants will go on to develop Congestive Heart Failure (CHF). Though the medical management for CHF may improve symptoms and slow disease progression, such treatment cannot restore a functioning myocardium. A therapy that could improve the myocardial remodeling process and reduce the incidence or severity of CHF following acute MI would provide a significant benefit. The characteristics and biologic activity of Prochymal®, along with a good safety profile in human trials to date, suggest that Prochymal® may be a good candidate for addressing this unmet medical need.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Prochymal®

Participants will receive Prochymal® single intravenous (IV) infusion at a dose of 200 x 10^6 human mesenchymal stem cells (hMSC), reconstituted in 80 mL, delivered at a rate of 2 mL/min, with a maximum rate of 5.0 x 10^6 hMSC/minute, and the participants will be followed for 24 months and remain in the study for up to 60 months.

Drug: Prochymal®
Intravenous infusion of ex vivo cultured adult human mesenchymal stem cells
Other Names:
  • Remestemcel-L
  • Placebo Comparator: Placebo

    Participants will receive Prochymal® placebo-matching single IV infusion at a dose of of 200 x 10^6 hMSC, reconstituted in 80 mL, delivered at a rate of 2 mL/min, with a maximum rate of 5.0 x 10^6 hMSC/minute, and the participants will be followed for 24 months and remain in the study for up to 60 months.

    Outcome Measures

    Primary Outcome Measures

    1. Change from Baseline in Cardiac Magnetic Resonance (CMR) imaging-determined End Systolic Volume (ESV) at Month 3 [Baseline, Month 3]

    Secondary Outcome Measures

    1. Left Ventricular End Systolic Volume [6 months]

    2. Infarct Size [3 and 6 months]

    3. Left Ventricular Ejection Fraction [3 and 6 months]

    4. Left Ventricular End Diastolic Volume [3 and 6 months]

    5. Number of Participants with Ventricular Arrhythmias [3 and 6 months]

    6. Duke Activity Status Index (DASI) Assessment [6, 12, and 24 months]

      The Duke Activity Status Index (DASI) is a brief, self-administered questionnaire that provides a standardized assessment of functional status and quality-of-life that correlates well with an objective measure of maximal exercise capacity. The scale ranges from 0 (unable to perform any tasks) to 58.20 (able to perform all tasks). Higher scores indicate a greater ability to perform daily activities.

    7. New York Heart Association (NYHA) Congestive Heart Failure Classification Status [6, 12, 24, and 60 months]

    8. Maximal Symptom-limited Exercise Test (Treadmill) [6 and 12 months]

    9. Number of Participants with Major Adverse Cardiac Events (MACE) [6, 12, 24, and 60 months]

    10. Overall Survival [60 months]

    11. Number of Participants with Adverse Events [3,6,12,24,60 months]
