The bad news keeps on coming for business associates of Martin Shrekli, the "bad boy" of pharmaceuticals who made a name for himself earlier this year when he hiked up the price of an AIDS drug from $13.50 to $750. Less than two weeks after it fired Shkreli as CEO, South San Francisco-based cancer drug research company KaloBios Pharmaceuticals Inc. filed for bankruptcy.
