E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the safety and feasibility of increasing the level of SERCA2a protein by viral gene transfer into patients with advanced heart failure who have had a mechanical pump (left ventricular assist device) that assists heart function implanted. |
|
E.2.2 | Secondary objectives of the trial |
1. Presence of viral DNA and RNA molecules will be measured in patient heart samples to evaluate whether the virus has been delivered to the heart cells 2. Function of the left ventricle will be assessed by echocardiography and physical activity tests (MVO2 treadmill testing and six-minute walk tests)
Depending on availability of heart samples the following may also be investigated: 3. The levels of SERCA protein in the heart will be measured 4. Changes in other proteins relevant for heart contraction such as phospholamban, sarcoplasmic reticulum release channel and Na2+/Ca2+-exchanger will be determined 5. The function of isolated heart muscle cells |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patients that have had a left ventricular assist device (LVAD) implanted for chronic heart failure 2. Patients are clinically stable in the opinion of the clinical team looking after the patient 3. Written informed consent
|
|
E.4 | Principal exclusion criteria |
1. <18 or >70 years of age at the time of consent 2. Pregnancy or within 6 months of giving birth 3. Women of child-bearing potential not using an effective method of contraception 4. Men not using an effective method of contraception 5. Suspected or active viral, fungal or parasitic infection within 48 hours prior to administration of IMP, in the opinion of the investigator*. 6. Patients participating in another clinical trial 7. 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. |

E.5 End points |
E.5.1 | Primary end point(s) |
Overall safety and feasibility of administering AAV1/SERCA2a to patients with left ventricular assist devices (LVAD) implanted.
Safety is defined as incidence of death and major adverse cardiovascular events, and out of range laboratory values. Both AAV1/SERCA2a treated cohorts (with and without presence of neutralising antibodies to AAV) will be compared to the placebo group.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
6 months post-randomisation |
|
E.5.2 | Secondary end point(s) |
Key comparisons will be performed between NAb+ and NAb- cohorts; additional comparisons will be performed between each of NAb+ and NAb- treated cohorts and placebo groups, including comparison of longitudinal changes from baseline (paired analyses). 1. Presence of exogenous viral vector genome in the myocardium measured by qPCR for the viral DNA 2. Left ventricular function assessed by echocardiography and exercise capacity (6MWT, MVO2) during minimal LVAD support (low/no flow settings depending upon device)
Depending on availability of cardiac tissue also: 3. Levels of SERCA2a protein 4. Other relevant proteins e.g. phospholamban, the sarcoplasmic reticulum calcium release channel, the Na+/Ca2+-exchanger. 5. Function of isolated myocytes
