Study summary

To compare the safety, tolerability and LDL-C response after 24 Weeks of monthly (every 4 weeks [Q4W]) subcutaneous (SC) dosing of LIB003 300 mg with monthly (Q4W) SC dosing of 420 mg evolocumab (Repatha®) in patients with HoFH on stable diet and oral LDL-C-lowering drug therapy

Read the detailed description

Patients with verified HoFH on stable and continuing doses of oral lipid lowering therapy will be randomized to either evolocumab 420 mg Q4W or LIB003 300 mg Q4W for 24 weeks (Period A). At Week 24, subjects will be crossed over to LIB003 if they were on evolocumab and vice versa for the next 24 weeks (Period B).

Interventions

What researchers measure

Primary outcomes

  1. Percent reduction in Low Density Lipoprotein Cholesterol (LDL-C) at week 24

    Change in serum LDL-C from baseline after 24 weeks

    Time frame: baseline to 24 weeks on each treatment

Secondary outcomes

  1. The incidence and severity of treatment emergent adverse events (TEAEs)

    safety and tolerability will be based on the incidence and severity of treatment emergent adverse events

    Time frame: baseline to 24 weeks on each treatment

Other outcomes

  1. Percent reduction in lipoprotein (a) [Lp(a)] at week 24

    Change in serum Lp(a) from baseline after 24 weeks

    Time frame: baseline to 24 weeks on each treatment

  2. Percent reduction in apolipoprotein B (Apo B) at week 24

    Change in serum Apo B from baseline after 24 weeks

    Time frame: baseline to 24 weeks on each treatment

  3. Presence of anti LIB003 antibodies (ADAs)

    Measurement of ADAs at baseline and various intervals

    Time frame: baseline to 24 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2019 to primary completion in Sep 2022, 33 months.

Of 21 phase 3 interventional studies under Homozygous Familial Hypercholesterolemia, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 34. This study's 33 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 29, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
