About this study

Official title: Pharmacodynamic Biomarkers to Support Biosimilar Development: Clinical Study 2: PCSK9 Inhibitors - Alirocumab and Evolocumab

This study is designed to assess pharmacokinetics and pharmacodynamics of evolocumab and alirocumab across an appropriate dose range to inform clinical trial operating characteristics for future clinical pharmacology pharmacodynamics similarity studies.

This is a randomized, placebo-controlled, single-dose, parallel arm study in 72 healthy subjects assigned to one of four dose groups (low, intermediate low, intermediate high, and high) of each drug (evolocumab and alirocumab ) or placebo.

Read the detailed description

This study is designed to assess pharmacokinetics and pharmacodynamics of evolocumab and alirocumab, two monoclonal antibodies that inhibit proprotein convertase subtilisin/kexin type 9 (PCSK9), across an appropriate dose range to inform clinical trial operating characteristics for future clinical pharmacology pharmacodynamics similarity studies.

This is a randomized, placebo-controlled, single-dose, parallel arm study in 72 healthy subjects assigned to one of four dose groups (low, intermediate low, intermediate high, and high) of each drug (evolocumab or alirocumab) or placebo. Evolocumab doses are 21, 35, 70, and 140 mg. Reslizumab doses are 15, 25, 50, and 100 mg . Each arm will include 8 subjects (4 male and 4 female).

Subjects will be admitted for treatment on day -1 and receive a single dose of study drug or placebo on day 1. Depending on the treatment arm, subjects will remain in confinement for one week and continue follow-up through day 42, 56, or 84.

Blood samples (approximately 5 mL per sample) will be collected for determination of plasma concentrations for study drug. Additional blood samples will be collected for lipid analysis and determination of low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B (apoB) (5 mL per sample; pharmacodynamic measure) and exploratory proteomics analyses (5 mL per sample).

Safety evaluations will include adverse event (AE) monitoring, vital sign measurements, and physical examinations. All AEs reported by the subject or observed by the investigator or clinical research unit (CRU) staff will be recorded. Any AE reported after the informed consent is signed and before study drug application will be recorded as medical history.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Baseline-adjusted Area Under Effect Curve (AUEC) for LDL-C for Evolocumab and Alirocumab

    The values and variability of AUEC for LDL-C at low, intermediate-low, intermediate-high, and high doses of evolocumab and alirocumab. AUEC was calculated as the baseline-subtracted area under the LDL-C concentration-time curve expressed in units of mg/(dL*day). More negative AUEC values represent greater reductions in LDL-C exposure from baseline. The standard deviation is noted in parentheses. For each subject and dose, the maximum decrease from baseline LDL-C was determined using all sampled timepoints. AUEC values were log-transformed and an ANCOVA model was used to calculate geometric means and 90% confidence intervals for each treatment group.

    Measured: Day -1 and 0h (pre-dose), 24h (post-dose); once on Day 2, 3, 4, 5, 7, 10, 14, 21, 28, 35, and 42 for all Arms. Additionally, once on Day 56 for Arms C, D, G, H, & I; and once on Day 70 and 84 for Arms D, H, & I.

  2. Maximum Change From Baseline for LDL-C for Evolocumab and Alirocumab

    The values and variability of maximum change from baseline for LDL-C at low, intermediate low, intermediate high, and high doses of evolocumab and alirocumab

    Measured: Day -1 and 0h (pre-dose), 24h (post-dose); once on Day 2, 3, 4, 5, 7, 10, 14, 21, 28, 35, and 42 for all Arms. Additionally, once on Day 56 for Arms C, D, G, H, & I; and once on Day 70 and 84 for Arms D, H, & I.

Secondary outcomes (7)

    The values and variability of AUEC for ApoB at low, intermediate-low, intermediate-high, and high doses of evolocumab and alirocumab. AUEC was calculated as the baseline-subtracted area under the ApoB concentration-time curve expressed in units of mg/(dL*day). More negative AUEC values represent greater reductions in ApoB exposure from baseline. The standard deviation is noted in parentheses. For each subject and dose, the maximum decrease from baseline ApoB was determined using all sampled timepoints.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Evolocumab and Alirocumab in people with Healthy Subjects and Pharmacokinetics, run by Food and Drug Administration (FDA) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Apr 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Baseline-adjusted Area Under Effect Curve (AUEC) for LDL-C for Evolocumab and Alirocumab (time frame: Day -1 and 0h (pre-dose), 24h (post-dose); once on Day 2, 3, 4, 5, 7, 10, 14, 21, 28, 35, and 42 for all Arms. Additionally, once on Day 56 for Arms C, D, G, H, & I; and once on Day 70 and 84 for Arms D, H, & I.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Apr 2024.
