The Medicines Company Announces Recommendation by Independent Data Monitoring Committee to Continue Inclisiran Phase III Trials Following [Third] Review of Unblinded Data

–More than 1,550 patient-years of safety data accumulated to date – a three-fold increase over total patient exposure through Phase II trials–

–At the time of IDMC review, [substantially] all patients in Phase III trials had received two doses of inclisiran or placebo–

–Phase III trials of inclisiran progressing as planned with no material safety observations to date–

The Medicines Company MDCO today announced that the Independent Data Monitoring Committee (IDMC) for the ongoing inclisiran Phase III trials has recommended that the trials continue as designed and conducted, without modification. The IDMC's recommendation was based on its planned review of unblinded safety and efficacy data from the trials.

The ORION Phase III studies with 18-months follow up were fully enrolled between November 2017 and March 2018, with 3,660 patients randomized 1:1 across three trials – ORION-9 (482 patients randomized), ORION-10 (1,561 patients randomized) and ORION-11 (1,617 patients randomized) – to receive either inclisiran or placebo. At the time of the IDMC review – its third since the ORION Phase III program began – [substantially] all randomized patients had been treated with two doses of inclisiran or placebo.

To date, more than 1,550 patient-years of safety data has been accumulated in the ORION Phase III program, a three-fold (or 1,000 patient-year) increase over the total patient exposure from the ORION Phase I and Phase II trials.

Commenting on the IDMC's recommendation, David Kallend, Chief Medical Officer of The Medicines Company said, "We are highly encouraged by the IDMC's clear recommendation, following its third review of unblinded data, from the ORION Phase III trials. We continue to advance the inclisiran Phase III program on a highly-efficient basis, with data readout expected in the second half of 2019."
