INTERVENTIONAL
Conditions
Summary
This randomized study is to assess LDL-C reductions at Week 12 with monthly (Q4W \[≤31 days\]) dosing of HST101 (lerodalcibep) 300 mg administered subcutaneously (SC) compared to placebo in patients with atherosclerotic cardiovascular disease (ASCVD) or very-high/high risk for ASCVD including Heterozygous familial hypercholesterolemia (HeFH) on a stable diet and oral LDL-C lowering drug therapy, followed by 36-week open-label treatment with subsequent 4-week follow-up for total 52-week long-term safety and efficacy evaluation.
Eligibility
Inclusion Criteria7
- Provision of written and signed informed consent form prior to any study-specific procedure;
- Male or female participants ≥18 years of age at the screening visit;
- Body weight ≥ 40 kg and body mass index (BMI) ≥18 and ≤35 kg/m2;
- On a stable diet and lipid-lowering oral drugs (such as statins, ezetimibe or Hybutimibe, omega-3 compounds, fenofibrate, nicotinic acid, etc.) for at least 4 weeks prior to the first drug administration
- LDL-C≥1.8 mmol/L (70 mg/dL) and TG≤4.52 mmol/L (400 mg/dL) at screening for ASCVD patients or those at very (ultra)-high risk for ASCVD, including patients with HeFH; LDL-C ≥ 2.6 mmol/L (100 mg/dL) and TG ≤ 4.52 mmol/L (400 mg/dL) at screening for patients at high-risk for ASCVD including patients with HeFH;
- Patients on a PCSK9 mAb at a dose of 75 mg, 140 mg, or 150 mg Q2W must undergo a washout period of ≥6 weeks after the last dose; for those on 300 mg or 420 mg Q4W, the washout period is ≥10 weeks following last dose;
- Female of childbearing potential must have a negative pregnancy test at the last screening visit and consent to use highly effective contraceptives during the trial and 3 months after the last dose of investigational drug.
Exclusion Criteria16
- Documented history of homozygous familial hypercholesterolemia (HoFH);
- Estimated glomerular filtration rate (eGFR)<30 mL/min/1.73m2;
- Active liver disease or hepatic dysfunction, history of liver transplant, and/or ALT or AST >2.5 × ULN at screening;
- Poorly controlled thyroid disorder including hypothyroidism or hyperthyroidism;
- Poorly controlled Type 1 or Type 2 diabetes mellitus defined as fasting blood glucose ≥11.0 mmol/L (200 mg/dL) and glycosylated hemoglobin (HbA1c) ≥ 9%;

- Pregnant or lactating women;
- Poorly controlled hypertension (SBP≥160 mmHg or DBP≥100 mmHg in a sitting position)
- Unexplained creatine kinase (CK) > 5 x ULN (retested once is needed if suspected to be related to excessive exercise or abnormal activity);
- LDL apheresis or plasma exchange within 2 months prior to the first dose;
- HIV, Treponema pallidum, or HCV antibody test positive, or HBV-DNA >ULN at screening;
- History of prescription drug abuse, illicit drug use or alcohol abuse within 6 months prior to screening;
- History of any major drug allergy, including allergy to protein biologics;
- Participate another clinical trial within 30 days or less than 5 half-lifes (drug) before screening, whichever is longer
