## About

EcoR1 Capital was established in 2012 by Oleg Nodelman. The firm operates as a registered investment adviser with a mandate centered on biotechnology companies. The strategy centers on long equity holdings in public biotech names alongside selective venture commitments. Confirmed positions include Zymeworks, AnaptysBio, Jazz Pharmaceuticals, Crinetics Pharmaceuticals and uniQure. The firm has also backed private companies such as ReCode Therapeutics, ElevateBio, Eikon Therapeutics, Aktis Oncology and Kumquat Biosciences. Activity spans the United States and Europe. The firm lists three named professionals. It maintains relationships with custodians including J.P. Morgan Securities, Goldman Sachs, BofA Securities and Jefferies. In January 2024 Nodelman spoke at the J.P. Morgan Healthcare Conference on biotech investment strategies. EcoR1 Capital sits alongside the Oleg & Heather Nodelman Joint Revocable Trust as the primary vehicle for the founder’s investment activities. The structure keeps discretionary management inside a single adviser entity rather than a multi-strategy platform.
