The Transendocardial Autologous Cells (hMSC) or (hMSC) and (hCSC) in Ischemic Heart Failure Trial. (TAC-HFT-II)

A Phase I/II, Randomized, Placebo-Controlled Study of the Safety and Efficacy of Transendocardial Injection of Autologous Human Cells (Mesenchymal or the Combination of MSC and Cardiac Stem Cells) in Patients With Chronic Ischemic Left Ventricular Dysfunction and Heart Failure Secondary to Myocardial Infarction.

Before initiating the full randomized study, a Pilot Safety Phase will be performed. In this phase the composition of cells administered via the Biosense Webster MyoStar NOGA Injection Catheter System will be tested. The randomized portion of the study will be conducted after a full review of the safety data from the pilot Phase by the Data safety monitoring board.

Following the Pilot Phase of five (5) Fifty (50) patients scheduled to undergo cardiac catheterization and meeting all inclusion/exclusion criteria will be evaluated at baseline.

Patients will be randomized in a 2:2:1 ratio to one of three Treatment Strategies.

  12. Have a coagulopathy = (INR > 1.3) not due to a reversible cause (i.e., Coumadin). Patients on Coumadin will be withdrawn 5 days before the procedure and confirmed to have an INR < 1.3. Patients who cannot be withdrawn from Coumadin will be excluded from enrollment
  13. Have known allergies to penicillin or streptomycin.
  14. Have a contra-indication to performance of an MRI scan.
  15. Be an organ transplant recipient.
  16. Have a clinical history of malignancy within 5 years (i.e., patients with prior malignancy must be disease free for 5 years), except curatively-treated basal cell carcinoma, squamous cell carcinoma, or cervical carcinoma.
  17. Have a non-cardiac condition that limits lifespan to < 1 year.
  18. Have a history of drug or alcohol abuse within the past 24 months.
  19. Be on chronic therapy with immunosuppressant medication, such as corticosteroids or TNFα antagonists.

  22. Be a female who is pregnant, nursing, or of childbearing potential while not practicing effective contraceptive methods. Female patients must undergo a blood or urine pregnancy test at screening and within 36 hours prior to injection.
