Inclisiran Versus Placebo for the Prevention of Major Adverse Cardiovascular and Limb Events in Patients Undergoing Percutaneous Coronary Intervention or Peripheral Endovascular Intervention

V-INTERVENTION will evaluate the effectiveness of inclisiran in preventing major cardiovascular and limb events in patients receiving percutaneous coronary or peripheral arterial revascularization. Inclisiran is a subcutaneous, twice-yearly injection that is FDA-approved as an adjunct with statin therapy and on the market to lower LDL-C in high-risk populations.

CKJX839D1US04R is a pragmatic, randomized, double-blind, parallel group, placebo-controlled, multicenter, event-driven study evaluating inclisiran sodium 300 mg subcutaneous administered on Day 1, Month 3 (Day 90), and every 6 months thereafter in participants presenting for elective or urgent percutaneous coronary or peripheral endovascular intervention (PCI or PVI). At the time of a successful revascularization procedure or up to 14 days following the procedure, participants will be randomized and administered the first dose of inclisiran or corresponding placebo in a 1:1 fashion, stratified by the type of index arterial revascularization procedure, either coronary (i.e., PCI) or lower extremity (i.e., PV).

The enrollment population will be representative of typical patients in the US with atherosclerotic cardiovascular disease, either coronary artery disease (CAD) or peripheral artery disease (PAD), and the trial endpoints are designed to be scientifically relevant and clinically meaningful to patients, clinicians, and other persons involved in the care of cardiovascular patients. The trial is designed to also understand how inclisiran therapy can be implemented in real-world clinical practice settings.

The expected enrollment of the trial is approximately 6,000 participants, randomized in a 1:1 fashion to receive inclisiran or placebo, within 14 days of successful percutaneous coronary or lower extremity peripheral endovascular intervention for symptomatic atherosclerotic cardiovascular disease (ASCVD).

Inclisiran sodium or corresponding placebo will be administered by s.c. injection to participants presenting for percutaneous coronary or peripheral endovascular intervention, in addition to usual care according to their individual medical history. All participants randomized to the treatment arm will receive inclisiran in addition to usual care per their regular physician direction, and those participants randomized to placebo will receive matching placebo, as well as usual care treatment, according to their treating physician.

Study duration is determined by event accrual consistent with the event-driven design, i.e., when approximately 2380 primary composite events have occurred and at least 50% of participants have at least 36 months of follow-up. Assuming 18 months of recruitment at a uniform rate, the last patients enrolled will have about 27 months of follow-up. Therefore, study duration should be approximately 4 years.

The study is event-driven, and thus, all participants will be treated (or followed in the case of permanent discontinuation of study drug) until the End of Study visit. As such, the planned duration of treatment cannot be stipulated for an individual participant. The estimated maximum treatment period for an individual participant is approximately 45 months, and the mean treatment duration is expected to be approximately 36 months.
