MYOHEART™ (Myogenesis Heart Efficiency and Regeneration Trial)

Status unconfirmed · Phase 1

Conditions studied: Congestive Heart Failure, Coronary Artery Disease, Myocardial Infarction

In brief

The MyoCell™ implantation using the MyoCath™ delivery catheter system may have the potential to add a new dimension to the management of post-infarct deterioration of cardiac function in subjects with congestive heart failure. Based on pre-clinical studies, implantation of autologous skeletal myoblasts may lead to replacement of non-functioning myocardial scar with functioning muscle and improvement in myocardial performance. Preliminary data in human subjects suggest skeletal myoblast implantation at the time of CABG may lead to the same effects. In principal, myoblast implantation by catheter delivery may offer the same therapeutic benefit. The present clinical study is to be conducted primarily to evaluate the safety of MyoCell™ implantation using the MyoCath™ delivery system and secondarily to evaluate the effect on regional myocardial function post treatment.

Who can join

Age: 30 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Defined region of myocardial dysfunction related to previous myocardial infarction(s) involving the anterior, lateral, posterior or inferior walls, > 12 weeks (84 days) old at the scheduled time of MyoCell™ implantation
• Patients who have had prior placement of an Implantable Cardioverter Defibrillator (ICD) which must be in place at least one month (30 days) prior to MyoCell™ implantation
• New York Heart Association (NYHA) Symptom Class II or III on optimal medical therapy
• Age > 30 and < 80 years old
• Need for revascularization has been ruled out by coronary angiogram or noninvasive stress testing within six months (180 days) of screening
• Able to undergo surgical biopsy of the skeletal muscle and successful culture of the harvested myoblasts Target region wall thickness > 6 mm by Echocardiography
• Left ventricular ejection fraction > 20% and < 40% by Radionuclide Ventriculography or Left Ventricular Angiography at screening

You may not qualify if…

• Myocardial infarction within 12 weeks (84 days) prior to investigational procedure

• Aortic stenosis greater than mild degree
• Left ventricular or atrial mural thrombus
• Chronic pulmonary disease
• Atherosclerosis and/or tortuosity of the aorta, iliac or femoral arteries of a degree which, in the judgment of the principal investigator, would impede or preclude the safe retrograde passage of the 8FR MyoCath™ delivery catheter
