NCT00534703

Brief Summary

The aim of the study is to determine the safety and feasibility of giving an adeno-associated viral vector expressing the sarcoplasmic reticulum calcium ATPase (SERCA2a), driven by the CMV promoter (AAV1-CMV-SERCA2a), to heart failure patients that have received a left ventricular assist device (LVAD) for an accepted clinical indication.

Outcome Measures

Primary Outcomes (1)

  • Overall Safety and Feasibility of Administering AAV1/SERCA2a to LVAD Patients

    Safety is defined as the incidence of patients experiencing death and major adverse cardiovascular events, and out of range laboratory values. Both AAV1/SERCA2a treated cohorts (NAb+ and NAb-) will be compared to the placebo group.

    6 months

Secondary Outcomes (5)

  • Number of Participants With Exogenous Viral Vector Genome in the Myocardium Measured by qPCR for the Viral DNA

    6 months

  • Left Ventricular Function (LVEF)

    6 months

  • Levels of SERCA2a Protein

    6 months

  • Other Relevant Proteins e.g. Phospholamban, the Sarcoplasmic Reticulum Calcium Release Channel, the Na+/Ca2+-Exchanger.

    6 months

  • Function of Isolated Myocytes

    6 months

Study Arms (2)

AAV1/SERCA2A

ACTIVE COMPARATOR

SERCA gene therapy

Genetic: AAV1/SERCA2a

Placebo

PLACEBO COMPARATOR

Placebo (saline solution)

Drug: Placebo

Interventions

AAV1/SERCA2a will be delivered by a percutaneous method in the catheter laboratory. Dose: 1x 10\^13 DRP (DNase resistant particles)

Also known as: MYDICAR (R)
AAV1/SERCA2A

Placebo aliquots will be of the same composition as the investigational medicinal product with the absence of the active ingredient and will be visually indistinguishable from the medicinal product. Placebo is prepared and handled exactly as above in a blinded fashion.

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients that have had a left ventricular assist device (LVAD) implanted for chronic heart failure, where chronic heart failure is defined as at least 6 months
  • Patients are clinically stable in the opinion of the clinical team looking after the patient
  • Written informed consent

You may not qualify if:

  • \<18 or \>70 years of age at the time of consent
  • Pregnancy or within 6 months of giving birth
  • Women of child-bearing potential not using an effective method of contraception
  • Men not using an effective method of contraception
  • Suspected or active viral, fungal or parasitic infection within 48 hours prior to administration of IMP, in the opinion of the investigator\*.
  • Patients at a high risk of thrombosis in the opinion of the investigator
  • Patients with a previous episode of LVAD thrombosis
  • Patients with persistently raised lactate dehydrogenase (LDH \>2.5 ULN)
  • Patients requiring triple anticoagulation i.e. warfarin and dual anti-platelet
  • Patients participating in another clinical trial
  • Patients unable to comply with the protocol mandated procedures for social or other reasons, in the opinion of the investigator and primary care physician
  • Eligible, enrolled and randomised patients who develop an infection will have study treatment delayed until 7 or more days after the time point when infection is no longer clinically evident.
