History.
Avalanche Biotechnologies was founded in 2006 by Tom Chalberg, Mark Blumenkranz, Mitchell Finer, and Steven Schwartz. Avalanche went public through an IPO in 2014, raising $102 million.
In 2015, co-founder Tom Chalberg stepped down as CEO following Phase IIa trial results that were labeled as "iffy".
In May 2016, Avalanche acquired Annapurna Therapeutics and changed its name to Adverum Biotechnologies. It also changed its ticker symbol on the Nasdaq exchange from AAVL to ADVM. In October 2016, former Annapurna Therapeutics CEO Amber Salzman became CEO of Adverum.
In May 2018, CEO Amber Salzman left Adverum, and Chief Medical Officer Athena Countouriotis resigned after less than one year in the job. Leone Patterson was named the new CEO of Adverum.
In September 2019, Adverum announced six month data from the first cohort of its phase I trial. The stock price dropped 50% due to investor concerns over deterioration of vision that these trial subjects suffered, as well as several reports of occular inflammation.
In June 2020, Laurent Fischer replaced Patterson as CEO of Adverum.
