Alnylam co-founder John Maraganore shares his journey from scientist to CEO, detailing how to build a biotech moonshot through perseverance.

An IP Block on a Biogen Project Forced a Redesign, Leading to a More Potent Drug

An intellectual property obstacle nearly terminated the bivalirudin project. This constraint forced the team to devise a novel "bivalent" molecule, which not only bypassed the patent issue but also resulted in a more potent drug. This illustrates how external limitations can unexpectedly trigger superior innovation.

Biogen's '20% Rule' Enabled the Unsanctioned Discovery of Anticoagulant Drug Bivalirudin

The blockbuster drug bivalirudin was discovered as an unsanctioned "20% time" project at Biogen. This policy, allowing scientists to explore personal interests, demonstrates how institutionalizing freedom for undirected research can lead to major, company-defining breakthroughs that would otherwise be missed in a rigid R&D structure.

Alnylam Survived the 'RNAi Winter' by Focusing Only on Genetically Validated Liver Targets

Facing industry-wide skepticism in 2010, Alnylam implemented a highly disciplined R&D strategy. They focused exclusively on targets that met strict criteria: liver expression (where delivery worked), human genetic validation (to de-risk biology), and an early biomarker. This strategic focus was key to their survival and success.

Alnylam Countered Skepticism with '5x15,' a Public Plan That Became an Internal Rallying Cry

When the industry lost faith in RNAi, Alnylam launched "Alnylam 5x15," a public five-year goal to advance five drugs into the clinic. While it took years to register externally, this bold commitment immediately became a powerful internal rallying cry, injecting hope and focus into the team during a demoralizing period.

Alnylam's $7.5B War Chest Was Built on a 50/50 Split of Equity and Pharma Partnerships

Over 20 years, Alnylam raised $7.5 billion. Remarkably, this was evenly split between equity financing from capital markets and non-dilutive funding from pharmaceutical partnerships. This balanced strategy was essential for financing a long, capital-intensive R&D journey while managing shareholder dilution.

Alnylam Weathered Risk-Off Markets with Visionary Capital from Pharma Partners like Merck

During a dismal post-tech-bubble market, Alnylam secured crucial early funding from pharmaceutical giants. These partners saw the long-term potential of RNAi and were willing to invest when public markets were risk-averse, highlighting pharma's role as a source of patient, visionary capital for platform technologies.

Merck's $1.1B Acquisition of a Competitor Validated Alnylam's Market and Boosted Investor Confidence

A pivotal moment for Alnylam came when competitor Surna Therapeutics was acquired by Merck for $1.1B. This external validation of the entire RNAi space significantly strengthened investor excitement about Alnylam, making it easier for them to raise capital and secure large partnerships. A rival's success can lift all boats.

Alnylam Co-founder's Pivotal Move to Business Was an Ultimatum from His Biogen CEO

John Maraganore's transition from science to business wasn't a choice but a reluctant career change forced upon him by Biogen's CEO. This involuntary pivot, which he initially resisted, provided the essential business experience he later needed to become a CEO, demonstrating how career-defining moments can be externally imposed.
