PERTH, Australia – Drug development is a risky business, and no one knows that better than U.S. Rep. Chris Collins (R-N.Y.), who likely won't forget how a failed clinical trial at Aussie biotech Innate Immunotherapeutics Ltd. last June ultimately ended his political career. But the thrifty little biotech isn't losing any sleep over Collins. It had already acquired some new assets and was readying them for the clinic when news broke that Collins was indicted for insider trading as a fallout from that failed trial.
