Highlights of Inclisiran Program
- Inclisiran, an investigational cholesterol-lowering therapy, was added to the pipeline from the Novartis acquisition of The Medicines Company.
- Inclisiran recently received a positive CHMP opinion and recommendation for marketing authorization in Europe and is under review by the US Food and Drug Administration
- Pooled data analyses from Phase III ORION-9, -10 and -11 showed that inclisiran consistently reduced low-density lipoprotein cholesterol (LDL-C) by approximately 51% in both male and female adult patients and in three age categories
- Expected Approvals by End of 2020 or H1 2021
Inclisiran is a double-stranded siRNA, conjugated with GalNAc allowing for targeted uptake by hepatocytes. In hepatocytes, inclisiran silences PCSK9 expression, increasing LDL-C receptor recycling and expression on the hepatocyte cell surface, thereby increasing LDL-C uptake by hepatocytes and lowering LDL-C levels in the circulation.
Inclisiran (ALN-PCSsc) is a long-acting, subcutaneously delivered, synthetic siRNA directed against PCSK9 that is conjugated to triantennary N-acetylgalactosamine carbohydrates. Its twice-yearly dosing by subcutaneous injection may integrate seamlessly into a patient’s healthcare routine.

Clinical Study Update for Inclisiran
Post-hoc analyses of Phase III ORION-9, -10 and -11 trials, evaluating the impact of age and gender on the efficacy and safety of inclisiran- The pooled analyses include data from inclisiran's ORION-9, -10 and -11 trials, which were multicenter, double-blind, randomized, placebo-controlled,18-month studies evaluating inclisiran in patients with HeFH (ORION-9), ASCVD (ORION-10) and ASCVD or ASCVD risk equivalents (ORION-11) on statin therapy who required additional LDL-C lowering.
- The primary endpoints for these studies were percentage change in LDL-C from baseline to 17 months and time-adjusted percentage change in LDL-C from baseline between 3 months and up to 18 months. The primary endpoints were achieved in all three studies.
- The pooled analyses assessed inclisiran's efficacy for lowering LDL-C, as well as safety and tolerability, across age ranges and by gender.
Impact of gender on the efficacy of inclisiran vs placebo:
- Percentage change between inclisiran and placebo in LDL-C at month 17 was consistent across women and men at −50.6% and −50.6%, respectively
- Time-adjusted LDL-C change between inclisiran and placebo at month 18 was consistent across women and men at −50.5% and −50.6%, respectively
- Across both analyses, inclisiran was reported to be well-tolerated, irrespective of age or gender. Injection site reactions (ISRs) were more frequent in female vs male patients and in the <65 population vs elder patients; all ISRs were transient and mild or moderate in terms of severity.
