Path to Alnylam 2020 R&D Day 2015 John Maraganore, Ph.D., Chief Executive Officer 1
What we re about: RNAi Therapeutics A New Class of Innovative Medicines Harness natural pathway Catalytic mechanism Mediated by small interfering RNA or sirna Therapeutic gene silencing Any gene in genome Distinct mechanism of action vs. other drug classes Unique opportunities for innovative medicines Clinically validated platform Human POC in multiple programs Papers in NEJM and Lancet 2
Where we were: Alnylam 5x15 TM Focused Product Development Pipeline for Genetic Medicines RNAi therapeutics as genetic medicines In 2011: 5 Key products in clinical development through 2015 Expect to greatly exceed 2011 guidance 8 in Clinic 2 in Phase 3 6-7 with Human POCs Product characteristics Genetically defined target/disease Existing Alnylam delivery platform Phase 1 proof of concept Clear and rapid development Significant commercial opportunity 3
Where we re going 4
