Study Details

Study Description

Brief Summary

AK102 is being developed for the treatment of HoFH. The study will be conducted in 2 parts, part 1 is open label, single arm study to evaluate the safety, tolerability and efficacy of PCSK9 inhibitor AK102, and part 2 is double blind, randomized, placebo controlled study to evaluate the efficacy and safety of PCSK9 inhibitor AK102. The treatment period will last 12 week.

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years and Older
Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  • Males and females, ≥18 years of age with a diagnosis of homozygous familial hypercholesterolemia by genetic confirmation or a clinical diagnosis based on a history of an untreated low-density lipoprotein cholesterol (LDL-C) concentration >500 mg/deciliter (dL) [13 millimoles/liter (mmol/L)] together with either xanthoma before 10 years of age or evidence of heterozygous familial hypercholesterolemia in both parents

  • Stable on pre-existing, lipid-lowering therapies (statins in combination with ezetimibe) for at least 4 weeks with no planned medication or dose change for the duration of study participation

  • Fasting central lab LDL-C concentration >130 mg/dL (3.4 mmol/L) and triglyceride concentration <400 mg/dL (4.5 mmol/L).

  • Body weight of 40 kilograms (kg) or greater at screening

Exclusion Criteria:
  • Received LDL plasma replacement therapy within 8 weeks before Investigational product administration

  • Received Lomitapide or Mipomersen within 5 months before Investigational product administration

  • Received prior treatment with PCSK9 inhibitors or AK102.

  • Unexplained creatine kinase (CK) ≥ 5 times the upper limit of normal (ULN)

  • Subjects with untreated chronic hepatitis B or chronic hepatitis B virus (HBV) DNA exceeding 500 IU/ mL or active hepatitis C virus (HCV) should be excluded. Subjects with non-active HBsAg carriers, treated and stable hepatitis B (HBV DNA <500 IU/ mL) , and cured hepatitis C can be enrolled. Subjects with positive HCV antibodies are eligible only if the HCV RNA test results are negative.

  • Known allergic reactions to any ingredients of AK102

  • Any other condition(s) that would compromise the safety of the patient or compromise the quality of the clinical study as judged by the Investigator and/or Medical Monitor.
