Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial Secondary Efficacy Endpoint: 6-minute walk test showed an improvement not seen in the control group, which was corroborated by a change in NYHA classification, while further deterioration in these parameters was observed in the control group. However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment. Further investigation in double-blind (sham treatment), placebo-controlled studies to evaluate autologous myoblasts in patients with CHF is warranted (MARVEL, CAUSMIC II).

Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial Secondary Efficacy Endpoint: 6-minute walk test showed an improvement not seen in the control group, which was corroborated by a change in NYHA classification, while further deterioration in these parameters was observed in the control group. However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment. Further investigation in double-blind (sham treatment), placebo-controlled studies to evaluate autologous myoblasts in patients with CHF is warranted (MARVEL, CAUSMIC II).

Primary Safety Endpoint: In this heart failure population previously fitted with an ICD, myoblast cell therapy was not associated with an increased incidence of arrhythmia, as documented by holter tape and ICD recordings, and appeared to be safe. Primary Efficacy Endpoint: The MUGA global LVEF remained unchanged, without overall sign of deterioration. Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial Secondary Efficacy Endpoint: 6-minute walk test showed an improvement not seen in the control group, which was corroborated by a change in NYHA classification, while further deterioration in these parameters was observed in the control group. However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment.

Primary Safety Endpoint: In this heart failure population previously fitted with an ICD, myoblast cell therapy was not associated with an increased incidence of arrhythmia, as documented by holter tape and ICD recordings, and appeared to be safe. Primary Efficacy Endpoint: The MUGA global LVEF remained unchanged, without overall sign of deterioration. Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial Secondary Efficacy Endpoint: 6-minute walk test showed an improvement not seen in the control group, which was corroborated by a change in NYHA classification, while further deterioration in these parameters was observed in the control group. However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment.

Primary Safety Endpoint: In this heart failure population previously fitted with an ICD, myoblast cell therapy was not associated with an increased incidence of arrhythmia, as documented by holter tape and ICD recordings, and appeared to be safe. Primary Efficacy Endpoint: The MUGA global LVEF remained unchanged, without overall sign of deterioration. Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial Secondary Efficacy Endpoint: 6-minute walk test showed an improvement not seen in the control group, which was corroborated by a change in NYHA classification, while further deterioration in these parameters was observed in the control group. However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment. Further investigation in double-blind (sham treatment), placebo-controlled studies to evaluate autologous myoblasts in patients with CHF is warranted (MARVEL, CAUSMIC II).

Primary Safety Endpoint: In this heart failure population previously fitted with an ICD, myoblast cell therapy was not associated with an increased incidence of arrhythmia, as documented by holter tape and ICD recordings, and appeared to be safe. Primary Efficacy Endpoint: The MUGA global LVEF remained unchanged, without overall sign of deterioration. Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial Secondary Efficacy Endpoint: 6-minute walk test showed an improvement not seen in the control group, which was corroborated by a change in NYHA classification, while further deterioration in these parameters was observed in the control group. However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment.

Primary Efficacy Endpoint: The MUGA global LVEF remained unchanged, without overall sign of deterioration.

However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment.

Primary Safety Endpoint: In this heart failure population previously fitted with an ICD, myoblast cell therapy was not associated with an increased incidence of arrhythmia, as documented by holter tape and ICD recordings, and appeared to be safe. Primary Efficacy Endpoint: The MUGA global LVEF remained unchanged, without overall sign of deterioration. Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial Secondary Efficacy Endpoint: 6-minute walk test showed an improvement not seen in the control group, which was corroborated by a change in NYHA classification, while further deterioration in these parameters was observed in the control group. However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment.

Primary Safety Endpoint: In this heart failure population previously fitted with an ICD, myoblast cell therapy was not associated with an increased incidence of arrhythmia, as documented by holter tape and ICD recordings, and appeared to be safe. Primary Efficacy Endpoint: The MUGA global LVEF remained unchanged, without overall sign of deterioration. Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial Secondary Efficacy Endpoint: 6-minute walk test showed an improvement not seen in the control group, which was corroborated by a change in NYHA classification, while further deterioration in these parameters was observed in the control group. However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo- control group with sham treatment. Further investigation in double-blind (sham treatment), placebo-controlled studies to evaluate autologous myoblasts in patients with CHF is warranted (MARVEL, CAUSMIC II).

However, none of these changes were statistically significant, and may be the result of a placebo effect in the absence of a true blind placebo control group with sham treatment. Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial However, these clinical benefits could not be substantiated by echocardiography and MUGA LVEF Placebo effect ? Appropriate surrogate end point markers ? (regional wall motion by MRI/ TTE, PV loop analysis) Technical issues Is this the correct target population for cell therapy per se? arrhythmia prone, irreversible CMP Validity of efficacy end points Placebo effect is a confounding factor, therefore double blind, placebo-control with sham treatment, adequately powered studies are warranted (Causmic II, Marvel) Percutaneous Intramyocardial Transplantation of Autologous Myoblasts: BIOHEART SEISMIC Trial SEISMIC Patient Selection Primary Inclusion Criteria: Prior MI > 90 days with region of myocardial dysfunction involving the anterior, lateral, posterior or inferior walls Placement of ICD 6 months prior to study entry LVEF at screening of ≥ 20% ≤ 45% (by MUGA scan) New York Heart Association (NYHA) Class II or III Patients on optimal pharmacological therapy for at least 2 months prior to study entry Need or feasibility for re-vascularization has been ruled out within 30 days of screening Minimum myocardial wall thickness of 5mm Age ≥ 18 and ≤ 75 years old SEISMIC Patient Selection Primary Exclusion Criteria: CABG within 180 days OR PCI within 90 days prior to scheduled MyoCell™ implantation Aortic valve replacement Exposure to any investigational drug or procedure within 1 month prior to study entry or enrolled in any concurrent study that could confound the data ICDs implanted less than 180 days or reprogrammed less than 90 days prior to cellular implantation Patients fitted with Bi-V pacers Patients unable to take anti-arrhythmic medications Evidence of left ventricular mural thrombus SEISMIC Study Flow SEISMIC Committees Independent Data Safety & Monitoring Board J.
