Monday's announcement quickly followed the news Friday that Shkreli had resigned from Turing Pharmaceuticals, the company that was catapulted into the national spotlight when he jacked up the price of a 62-year-old drug used to treat rare but severe infections in HIV and cancer patients.
In a statement, KaloBios, said that Tony Chase also stepped down from the company's board. Chase joined the board in November when Shkreli took charge of the company.
Martin Shkreli:
• Former hedge fund manager accused of stealing US$11 million.
• FBI describes case as a "securities fraud trifecta of lies, deceit and greed".
• Released after posting a US$5 million bond.
• Gained notoriety when his company Turing Pharmaceuticals raised the price of Daraprim from US$13.50 a tablet to US$750.
• The move, and his arrogant response to the controversy, was angrily denounced by US politicians.
