Trial Outcomes & Findings for Study of Alirocumab (REGN727/SAR236553) in Patients With Heterozygous Familial Hypercholesterolemia (HeFH) Undergoing Low-density Lipoprotein (LDL) Apheresis Therapy (NCT NCT02326220)

NCT ID: NCT02326220

Last Updated: 2020-05-01

Results Overview

Rate of apheresis treatments were normalized by the number of planned apheresis treatments according to each participant's established schedule at screening, week -10 to week -2. The normalized rate of apheresis was defined for each participant as the number of actual apheresis treatments received from week 7 to week 18 divided by the number of planned apheresis treatments per randomization strata at baseline (6 for Q2W and 12 for QW).

Participant Flow

The study was conducted in Germany and the United States between 09 Mar 2015 and 20 Apr 2016. A total of 76 participants were screened, of which 62 were enrolled and randomized in the study.

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.

Measure
Placebo Q2W (Double Blind Period)
Placebo (for alirocumab) subcutaneous (SC) injection Q2W up to Week 16. Apheresis frequency was fixed (weekly or bi-weekly) until Week 6, then it was adjusted according to the response to treatment. (Participants 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 participants were being treated with the maximally tolerated clinically-relevant LMT).
Alirocumab 150 mg Q2W (Double Blind Period)
Alirocumab 150 mg SC injection Q2W up to Week 16. Apheresis frequency was fixed (weekly or bi-weekly) until Week 6, then it was adjusted according to the response to treatment. (Participants 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 participants were being treated with the maximally tolerated clinically-relevant LMT).
Alirocumab 150 Q2W (Open Label Treatment Period)
Alirocumab 150 mg SC injection Q2W starting from Week 18 up to Week 76 or until alirocumab became commercially available in the subject's country, whichever occurred first. Apheresis treatment not required in the open-label treatment period and could be stopped or continued at the investigator's discretion. (All participants were being treated with the maximally tolerated clinically-relevant LMT.)

PRIMARY outcome

Timeframe: Week 7 to Week 18 (before start of open-label treatment)

Population: Primary intent-to-treat (ITT) population defined as all randomized participants and were analyzed according to the treatment group allocated by randomization.

Rate of apheresis treatments were normalized by the number of planned apheresis treatments according to each participant's established schedule at screening, week -10 to week -2. The normalized rate of apheresis was defined for each participant as the number of actual apheresis treatments received from week 7 to week 18 divided by the number of planned apheresis treatments per randomization strata at baseline (6 for Q2W and 12 for QW).

SECONDARY outcome

Timeframe: Baseline and at Week 6

Population: Analysis was performed on ITT population that included all randomized particpants with baseline and at least one post-baseline pre-apheresis calculated LDL-C value up to week 6, analyzed according to the treatment group allocated by randomization.

Adjusted Least-squares (LS) means and standard errors at Week 6 were obtained from a mixed-effect model with repeated measures (MMRM) to account for missing data. All available post-baseline data from Week 2 to Week 18 regardless of status on or off-treatment were used in the model (ITT analysis).

SECONDARY outcome

Timeframe: Week 15 up to Week 18 (before the start of open-label treatment dose)

Population: Analysis was performed on ITT population.

Rate of apheresis treatments were normalized by the rate by the number of actual apheresis treatments according to received from week 15 to week 18 divided by the planned apheresis treatments per randomization strata at baseline (2 for Q2W and 4 for QW). Only legitimate apheresis treatment skipping per point-of-care LDL-C value is counted as "apheresis not occurred". Missing apheresis treatment information (any reason) from week 7 to week 18 is assigned an outcome of the apheresis treatment occurred at the visit (i.e. impute 1 apheresis treatment for that visit).

SECONDARY outcome

Timeframe: From Baseline to Week 18

Population: Analysis was performed on Well-Being analysis set included all randomized and treated participants with complete baseline and complete post-baseline evaluations of the 22-question well-being questionnaire.

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 participants. 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).
