Alipogene Tiparvovec for the Treatment of LPLD Patients

Phase 2

Registration Number
NCT02904772
Lead Sponsor
UniQure Biopharma B.V.
Brief Summary

The aim of the study is to provide further confirmatory evidence of clinical benefit in LPLD patients treated with alipogene tiparvovec by assessing both the "clinical response" (as defined by a range of parameters), and "the metabolic response" (postprandial CM metabolism) in LPLD patients with and without an immunosuppressant regimen.

Detailed Description

This is a prospective, interventional, randomised, open-label, parallel group study evaluating the clinical response as well as the dynamics of postprandial chylomicron metabolism in patients treated with alipogene tiparvovec with and without immunosuppressants. The study will be conducted in 12 LPLD patients who will be randomised into the Immuno+ (cyclosporin and mycophenolate mofetil) or the Immuno- group.

alipogene tiparvovec with ISalipogene tiparvovecPatients in the Immuno+ group will receive an immunosuppressant regimen to be initiated three days prior to alipogene tiparvovec administration. The regimen is to be continued for 12 weeks: Cyclosporins (3 mg/kg/day) and mycophenolate mofetil (2 x 1 g/day). Patients will receive IV bolus of 1mg/kg of methyl Prednisolone half an hour prior to IMP administration.
alipogene tiparvovec with ISPrednisolonePatients in the Immuno+ group will receive an immunosuppressant regimen to be initiated three days prior to alipogene tiparvovec administration. The regimen is to be continued for 12 weeks: Cyclosporins (3 mg/kg/day) and mycophenolate mofetil (2 x 1 g/day). Patients will receive IV bolus of 1mg/kg of methyl Prednisolone half an hour prior to IMP administration.
alipogene tiparvovec with ISCyclosporinsPatients in the Immuno+ group will receive an immunosuppressant regimen to be initiated three days prior to alipogene tiparvovec administration. The regimen is to be continued for 12 weeks: Cyclosporins (3 mg/kg/day) and mycophenolate mofetil (2 x 1 g/day). Patients will receive IV bolus of 1mg/kg of methyl Prednisolone half an hour prior to IMP administration.
alipogene tiparvovec without ISalipogene tiparvovecPatients in the Immuno- group will not receive an immunosuppressant regimen during 12 weeks. Patients will receive IV bolus of 1mg/kg of methyl Prednisolone half an hour prior to IMP administration.
alipogene tiparvovec with ISMycophenolate mofetilPatients in the Immuno+ group will receive an immunosuppressant regimen to be initiated three days prior to alipogene tiparvovec administration. The regimen is to be continued for 12 weeks: Cyclosporins (3 mg/kg/day) and mycophenolate mofetil (2 x 1 g/day). Patients will receive IV bolus of 1mg/kg of methyl Prednisolone half an hour prior to IMP administration.
alipogene tiparvovec without ISPrednisolonePatients in the Immuno- group will not receive an immunosuppressant regimen during 12 weeks. Patients will receive IV bolus of 1mg/kg of methyl Prednisolone half an hour prior to IMP administration.
Primary Outcome Measures
NameTimeMethod
The Clinical Response of alipogene tiparvovec in LPLD patients2 years

The overall clinical response of alipogene tiparvovec in LPLD patients will be assessed compared to baseline, by a combination of measurements, of which each gives relevant information to obtain enough and solid evidence in a small trial. Each of these outcome measures will be evaluated in combination with the results of other measures (to get an overall conclusion relating the clinical response). Descriptive methods will be used (so no formal statistical analyses will be performed), due to the specific nature and the small sample size of a rare disease trial.

The long term effect of alipogene tiparvovec on post prandial metabolism of chylomicrons (ppCM) in LPLD patients.2 years

CM \[3H\]-activity will be assessed during ppCM testing pre- and post-dose, compared to baseline.

Secondary Outcome Measures
NameTimeMethod
Immuno response of alipogene tiparvovec by analysis of antibody formationBaseline, 1 and 2 years post dose

The immuno response of alipogene tiparvovec will be assessed by measuring the antibody formation compared to baseline.

Immuno response of alipogene tiparvovec by analysis of T-cell responseBaseline, 1 and 2 years post dose

T-cell responses against alipogene tiparvovec will be assessed by measuring the T-cell response compared to baseline.
