Blackstone and Alnylam Enter Into $2 Billion Strategic Financing Collaboration to Accelerate the Advancement of RNAi Therapeutics

The deal is anchored by Blackstone’s purchase of 50 percent of the royalties owed to Alnylam on global sales of inclisiran, an investigational RNAi therapeutic for the treatment of hypercholesterolemia, currently under review by the U.S. Food and Drug Administration. Inclisiran is a twice-a-year, subcutaneously injected RNAi therapeutic that has been shown in a comprehensive Phase 3 program to reduce low-density lipoprotein (LDL) or “bad” cholesterol with an acceptable safety profile. If approved, this medicine is expected to help patients lower LDL cholesterol, a major risk factor for cardiovascular disease, the leading cause of mortality in the U.S. and globally.

The strategic financing collaboration, led by Blackstone Life Sciences and GSO Capital Partners (“GSO”), Blackstone’s credit platform, is expected to enable Alnylam’s achievement of a self-sustainable financial profile without need for future equity financing, accelerating the commercial potential of Alnylam’s rapidly advancing product portfolio. The investment by multiple Blackstone businesses will support the development and delivery of promising medicines to the patients who need them and is one of the largest ever private financings of a biotech company.

The transaction includes the inclisiran royalty monetization, corporate debt, purchase of Alnylam equity, and funding for certain R&D activities related to the clinical advancement of two Alnylam investigational RNAi therapeutic programs in cardiovascular disease.

Specifically, the transaction is comprised of the following components:

1. $1 billion in committed payments, led by Blackstone Life Sciences, to acquire 50 percent of Alnylam’s royalties and commercial milestones for inclisiran;
2. Up to $750 million in a first lien senior secured term loan led by GSO;
3. Up to $150 million from Blackstone Life Sciences for development of Alnylam’s cardiometabolic programs vutrisiran and ALN-AGT (to be established based upon a non-binding letter of intent);
4. $100 million purchase of Alnylam common stock.

“Alnylam is focused on building a top-tier biopharmaceutical company, advancing RNAi therapeutics as a whole new class of medicines with transformative potential for patients around the world. This exciting new relationship with Blackstone brings us much closer to that goal, securing our bridge towards a self-sustainable financial profile that we believe can now be achieved without any need for Alnylam to access the equity markets in the future,” said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. “A central component of this strategic relationship is a partial monetization of our royalty for inclisiran. If approved, we believe this therapy holds enormous promise as a potential game-changer in hypercholesterolemia management. We are pleased to retain half of the royalties we receive from Novartis, allowing Alnylam to benefit from inclisiran’s anticipated future success. We couldn’t be more pleased to enter into this highly innovative arrangement with Blackstone, which has shown a significant commitment to Alnylam’s future and alignment with our long-term vision.”

“Blackstone is uniquely positioned to provide customized, one-stop-shop financing solutions at scale while establishing development collaborations with the world’s leading biotech companies. Alnylam’s RNAi technology represents one of the most promising and rapidly advancing frontiers in biology and drug development today, and aligns perfectly with our investment strategy,” said Nicholas Galakatos, Ph.D., Global Head of Blackstone Life Sciences. “Our collaboration with Alnylam provides non-dilutive access to capital to advance important new medicines in development across several disease indications including heart disease, the leading cause of death in the U.S. and globally.”

“We’re thrilled to be able to partner with Blackstone Life Sciences to provide a customized solution for Alnylam, whose approved therapies provide important new options for patients,” said Dwight Scott, Global Head of GSO. “GSO’s capital will support Alnylam during a period of global growth as it continues to launch its medicines and pursue innovative RNAi approaches to bring new therapies to market and ultimately to patients around the globe.”

Alnylam, an existing tenant of Blackstone Real Estate company BioMed Realty, is also in discussions with BioMed to expand its footprint in Cambridge, MA.

About Inclisiran
Inclisiran, an investigational cholesterol-lowering treatment, was added to the Novartis pipeline via its acquisition of The Medicines Company. Inclisiran will potentially be the first and only LDL-C lowering siRNA treatment. It is intended to be administered by a healthcare professional by subcutaneous injection with an initial dose, again at 3 months and then every 6 months thereafter. Its twice-yearly dosing by subcutaneous injection may integrate seamlessly into a patient’s healthcare routine. As a siRNA, inclisiran is thought to harness the body’s natural process of clearing LDL-C from the bloodstream. Inclisiran is a double-stranded siRNA, conjugated on the sense strand with triantennary N-acetylgalactosamine (GalNAc) to facilitate uptake by hepatocytes. In hepatocytes, inclisiran increases 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. Data from each of the Phase III studies was recently published online, ahead of print, in The New England Journal of Medicine. A cardiovascular outcomes trial, ORION-4, is ongoing.

In the Phase III studies, inclisiran was reported to be well-tolerated with a safety profile similar to placebo. The most common adverse reactions reported (≥3% of patients treated with inclisiran and occurring more frequently than placebo) were, diabetes mellitus, hypertension, nasopharyngitis, arthralgia, back pain, dyspnea, bronchitis and upper respiratory tract infection. Adverse events at the injection site were more frequent with inclisiran than placebo and were generally mild and none were severe or persistent.

Novartis has obtained global rights to develop, manufacture and commercialize inclisiran under a license and collaboration agreement with Alnylam Pharmaceuticals.

About RNAi
RNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines, known as RNAi therapeutics, is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam’s RNAi therapeutic platform, function upstream of today’s medicines by potently silencing messenger RNA (mRNA) – the genetic precursors – that encode for disease-causing proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases.
