Clinical Trial Summary

This study is to assess LDL-C reductions at Week 52 with monthly (Q4W [≤31 days]) dosing of LIB003 (lerodalcibep) 300 mg administered subcutaneously (SC) compared to placebo in patients with very-high risk for CVD on a stable diet and oral LDL-C lowering drug therapy.

Description:

Randomized, double-blind, placebo-controlled, Phase 3 study of 52 weeks duration.

Patients who fulfill the inclusion and exclusion criteria will be enrolled at up to 60 sites in the United States, Canada, Europe, South Africa, Asia, Australasia, and the Middle East. Patients will be randomized in a 2:1 ratio to LIB003 or placebo. The total study duration will be up to 63 weeks which includes up to a Screening Period and 52 weeks of study drug treatment. Following randomization patients will be dosed and seen in the clinic Q4W (≤31 days).

Eligibility

Inclusion Criteria:

• Provision of written and signed informed consent prior to any study-specific procedure;

• Male or female =18 years of age at the first Screening Visit;

• Weight of =40 kg (88 lb) and body mass index (BMI) =17 and =42 kg/m2;

• At Screening or post Washout/Stabilization), =70 mg/dL and TG =400 mg/dL while on stable lipid-lowering oral drug therapy (i.e., maximally tolerated statin with or without ezetimibe); Patients unable to tolerate approved doses of a statin may take lower than approved doses and dose less frequently than daily as long as the dose and dosing frequency is consistent; Patients with documentation of inability to tolerate any statin at any dose, or history of rhabdomyolysis, may also participate;

• On a stable diet and lipid-lowering oral therapies (such as statins, ezetimibe, bile-acid sequestrants, OM-3 compounds, fenofibrate, bezafibrate, nicotinic acid, and bempedoic acid) or combinations thereof for at least 4 weeks

• Patients on a PCSK9 mAb at a dose of 75 mg, 140 mg, or 150 mg Q2W must undergo a washout period of =4 weeks after the last dose; for those on 300 mg or 420 mg Q4W (=31 days) the washout period is =8 weeks following last dose; 8. Females of childbearing potential must be using a highly effective form of birth control if sexually active and have a negative urine pregnancy test at the last Screening Visit;

Exclusion Criteria:

• Use of prohibited oral lipid-lowering agents mipomersen or lomitapide within 6 months of screening, gemfibrozil within 6 weeks of screening, LDL or plasma apheresis within 2 months prior to randomization; received other investigational agent(s) such as PCSK9 or Lp(a) siRNA or locked nucleic acid-reducing agents within 12 months of the Screening Visit;

• Documented history of HoFH defined clinically or genetically

• History of any prior or active clinical condition or acute and/or unstable systemic disease compromising patient inclusion, at the discretion of the Investigator

• Females of childbearing potential who are sexually active, not using or unwilling to use a highly effective form of contraception, pregnant or breastfeeding, or who have a positive urine pregnancy test at the last Screening Visit;

• Moderate to severe renal dysfunction, defined as an eGFR <30 mL/min/1.73m2

• Active liver disease or hepatic dysfunction, history of liver transplant, and/or ALT or AST >2.5 × the ULN as determined by central laboratory analysis at screening

• Uncontrolled thyroid disease: hyperthyroidism or hypothyroidism 9. Uncontrolled Type 1 or Type 2 DM, defined as FBS =200 mg/dL or HbA1C =9%; 10. Uncontrolled serious cardiac arrhythmia, MI, unstable angina, PCI, CABG, placement of implantable cardioverter defibrillator or biventricular pacemaker, aortic valve surgery, or stroke within 3 months prior to the Screening Visit; 11. Planned cardiac surgery or revascularization;
