NCT03705234

Brief Summary

ORION-4 is a research study coordinated by the University of Oxford and co-sponsored by The University of Oxford and Novartis (Protocol: CTSU\_MDCO-PCS-17-01 (CKJX839B12301)). The study aims to find out if a new cholesterol-lowering injection (inclisiran) safely lowers the risk of heart attacks and strokes in people who have already had one of these conditions, or who have had an operation or procedure to treat blocked arteries.

Outcome Measures

Primary Outcomes (1)

  • Number of participants with a major adverse cardiovascular event (MACE)

    Defined as time to first occurrence - during the scheduled treatment period - of: * Coronary heart disease (CHD) death; * Myocardial infarction; * Fatal or non-fatal ischemic stroke; or * Urgent coronary revascularization procedure.

    Median follow-up of 5-years

Secondary Outcomes (3)

  • Number of participants with MACE among those recorded to be taking high-intensity statin at baseline

    Median follow-up of 5-years

  • Number of participants with a composite of CHD death or myocardial infarction

    Median follow-up of 5-years

  • Number of participants with cardiovascular death

    Median follow-up of 5-years

Study Arms (2)

Inclisiran

EXPERIMENTAL

Inclisiran sodium 300 milligrams (mg) will be administered as a SC injection at randomization, 3 months and then every 6 months.

Drug: Inclisiran

Placebo

PLACEBO COMPARATOR

Placebo will be administered as SC injections of saline solution at randomization, 3 months and then every 6 months.

Drug: Placebo

Interventions

Inclisiran is a small interfering ribonucleic acid (RNA) that inhibits PCSK9 synthesis.

Inclisiran

Placebo will be supplied as sterile normal saline (0.9% sodium chloride in water for injection).

Also known as: Saline solution
Placebo

Eligibility Criteria

Age40 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • History or evidence of at least one of the following:
  • Prior MI; or
  • Prior ischemic stroke; or
  • Peripheral artery disease as evident by prior lower extremity artery revascularization or aortic aneurysm repair.
  • Minimum age is 40 years for men and 55 years for women

You may not qualify if:

  • None of the following must be satisfied (based on self-reported medical history):
  • Acute coronary syndrome or stroke less than 4 weeks before the Screening visit or during the Run-in period;
  • Coronary revascularization procedure planned within the next 6 months;
  • Known chronic liver disease;
  • Current or planned renal dialysis or transplantation;
  • Previous exposure to inclisiran or participation in a randomized trial of inclisiran;
  • Previous (within about 3 months), current or planned treatment with a monoclonal antibody targeting PCSK9, or with a drug known to be contra-indicated with inclisiran (none currently known);
  • Known to be poorly compliant with clinic visits or prescribed medication;
  • Medical history that might limit the individual's ability to take trial treatments for the duration of the study (e.g. severe respiratory disease; cancer or evidence of spread within approximately the last 5 years, other than non-melanoma skin cancer; or history of alcohol or substance misuse) or may put the individual at significant risk in the opinion of the investigator (or their authorised deputy) if he/she were to participate in the trial;
  • Women of child-bearing potential, current pregnancy, or lactation;
  • Current participation in a clinical trial with an unlicensed drug or device; or
  • Staff personnel directly involved with the study and any family member of the investigational study staff.
