General information about the trial
|
|||
Main objective of the trial |
The primary objective of the study was to evaluate the effect of alirocumab 150 mg every 2 weeks (Q2W) in comparison with placebo on the frequency of low-density lipoprotein (LDL) apheresis treatments in subjects with heterozygous familial hypercholesterolemia (HeFH) undergoing weekly or bi-weekly LDL apheresis therapy.
|
||
Protection of trial subjects |
The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Council for Harmonization (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed.
|
||
Background therapy |
Subjects undergoing LDL apheresis therapy every 1 or 2 weeks were enrolled in this study while maintaining background lipid modifying therapy (LMT) treatment throughout the study. All patients were being treated with the maximally tolerated clinically-relevant LMT. | ||

Recruitment
|
||||||||||||||||||||||
Recruitment details |
The study was conducted in Germany and the United States between 09 Mar 2015 and 20 Apr 2016. A total of 76 subjects were screened, of which 62 were enrolled and randomized in the study. | |||||||||||||||||||||
Pre-assignment
|
||||||||||||||||||||||
Screening details |
Randomization was stratified according to the frequency of the apheresis procedure (every 7 or 14 days) and Lipoprotein (a) (Lp [a]) levels (normal or elevated). Assignment to treatment arms was done using an Interactive Voice/Web Response System in 1:2 ratio to placebo or alirocumab 150 mg Q2W. | |||||||||||||||||||||

Notes [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period. Justification: Entry into the open-label treatment period was available only to patients who were study participants in a country in which alirocumab was not commercially available. |

Alirocumab 150 mg Q2W vs Placebo Q2W | ||||||||||||
Statistical analysis description |
Analysis was performed using the ranked analysis of covariance (ANCOVA) model with baseline frequency of the apheresis procedure (QW or Q2W) and Lipoprotein (a) (Lp [a]) levels (normal or elevated) as fixed effect and the baseline LDL-C level as a covariate. Median treatment difference and 95% confidence interval (CI) was derived from the Hodges-Lehmann (H-L) estimation and Moses distribution free CI, respectively.

Change From Baseline in W-BQ22 (Well-being Questionnaire) Index Score at Week 18 | ||||||||||||
End point description |
The W-BQ22 (well-being) questionnaire was a standardized and generic instrument used for measuring the impact of hypercholesterolemia and treatment on well-being of subjects. The general well-being score was calculated as the sum of 22 questions in the W-BQ22 questionnaire (each question scored from 0 to 3 [0 = not at all and 3 = all the time]). Total score for 22 questions range from 0 to 66 [0 = worst condition and 66 = best well-being condition). Analysis was performed on Well-Being analysis set included all randomized and treated subjects with complete baseline and complete post-baseline evaluations of the 22-question well-being questionnaire.

Adverse events information

Timeframe for reporting adverse events |
All Adverse Events (AEs) were collected from signature of the informed consent form up to the final study end visit (maximum duration: 46 weeks) regardless of seriousness or relationship to investigational product.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Adverse event reporting additional description |
Reported AEs are treatment-emergent AEs developed/worsened during ‘on treatment period’(double blind treatment-emergent period: time from first dose of study drug to last double-blind dose+70 days, prior to first open-label dose of study drug; open-label treatment emergent period: time from first open-label dose of study drug to last dose+70 days).

15 Apr 2015 |
Following changes were made:
- Allowed flexibility in apheresis treatment eligibility requirements;
- Added an open-label treatment period;
- Updated site locations;
- made minor clarifications. |
||
06 Jul 2015 |
Following changes were made:
- Updated eligibility requirements that were consistent with the known safety profile of the study drug;
- Made a minor clarification to the text regarding the apheresis schedule. |
||
22 Sep 2015 |
Following changes were made:
-Noted that entry into the open-label treatment period was only available to subjects who were study participants in a country in which alirocumab not commercially available (sites in Germany);
-Indicated that treatment in the open-label period of the study would continue for a maximum of 76 weeks or until alirocumab was commercially available in the subject’s country, whichever comes first (sites in Germany);
-Clarified that subjects who chose not to participate in the open-label treatment period, or who were study subjects in a country in which alirocumab was commercially available (sites in the US), would be seen at week 26 for the double-blind treatment period end of study visit. These subjects were considered to have completed the study at this end of study visit;-
-Specified that the primary analysis would be performed following the completion of the double-blind treatment period and made minor administrative corrections/clarifications. |
