The Medicines Company Announces 5th Review of Un-blinded Data and Recommendation by Independent Data Monitoring Committee to Continue Inclisiran Phase 3 Trials

The Medicines Company (NASDAQ: MDCO) today announced that the 5th review of un-blinded safety and efficacy data by the Independent Data Monitoring Committee (IDMC) for inclisiran Phase 3 trials has been completed. The IDMC has once again recommended that the trials continue as designed and conducted, without modification.

“I am pleased and excited with the progress of the ORION program as we count down to pivotal Phase 3 results in the 3rd quarter. 2019 is a momentous year for inclisiran, a first in class therapy with the potential to deliver potent, durable and consistent lowering of LDL-C levels via twice-a-year dosing. The potential to address the world’s largest health problem and help patients around the world is enormous. With full commercial rights in all geographies, we are well placed to harness the intrinsic value of inclisiran,” said Mark Timney, Chief Executive Officer of The Medicines Company.

The ORION Phase 3 studies with 18-months treatment and 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, it’s 5th since the ORION Phase 3 program began, all randomized patients had been treated with three doses, and approximately 2,000 patients had completed a follow-up visit 60-days after the third dose of study medication. To date, more than 2,450 patient-years of inclisiran safety data have been accumulated in the ORION program, a seven-fold (or 2,120 patient-year) increase over the total patient exposure from the ORION Phase 1 and Phase 2 trials.

Commenting on the IDMC’s recommendation, David Kallend, Chief Medical Officer of The Medicines Company said, “Once again, we are highly encouraged by the IDMC’s clear recommendation, following its 5th review of unblinded data from the ORION Phase 3 trials. We continue to advance the inclisiran Phase 3 program on a highly-efficient basis, and now begin an exciting countdown as patients receive their fourth and final dose of study medication, and we progress to final data readout, as planned, in the second half of 2019.”

Commercial opportunity

In the US alone, 67.5 million individuals are estimated to have sufficient cardiovascular risk to warrant lipid-lowering therapy. 27.5 million of these individuals are at a significantly elevated risk, either because of confirmed cardiovascular disease or LDL-C levels above 190 mg/dl. Of this higher risk group, 15.1 million are currently treated with lipid-lowering therapies, but only one out of five (or 2.4 million) is successfully reaching LDL-C targets with current therapies. This implies a population of at least 12.7 million Americans who could benefit from inclisiran, a first in class therapy with the potential to deliver potent, durable and consistent lowering of LDL-C levels via twice-a-year dosing.

About inclisiran

Inclisiran is an investigational GalNAc-conjugated RNA interference therapeutic, which inhibits the synthesis of PCSK9 protein in liver cells, thereby reducing liver cell LDL-receptor turnover, and lowering plasma LDL-C.

The Medicines Company and Alnylam Pharmaceuticals, Inc. are collaborating in the advancement of inclisiran pursuant to their 2013 agreement. Under the terms of that agreement, Alnylam completed certain pre-clinical studies and the Phase 1 clinical study, with The Medicines Company leading and funding the development of inclisiran from Phase 2 forward, as well as potential commercialization.
