Durus Life Sciences Master Fund

Durus Life Sciences Master Fund was a Connecticut-based hedge fund that specialized in the healthcare and biotechnology sectors during the early 2000s. Managed by Scott Sacane under Durus Capital Management, the fund is primarily known for a high-profile securities scandal in 2003 involving the failure to disclose massive ownership stakes in companies such as Aksys and Esperion Therapeutics. The revelation of these undisclosed positions led to a liquidity crisis, the fund's eventual collapse, and significant legal proceedings. At its peak, the fund was a major institutional investor in small-cap life science and medical device companies.
