Commitments and Contingencies Disclosure [Abstract]
Litigation	Litigation The Company records an estimate of a loss when the loss is considered probable and estimable. Where a liability is probable and there is a range of estimated loss and no amount in the range is more likely than any other number in the range, the Company records the minimum estimated liability related to the claim in accordance with ASC Topic 450-Contingencies. As additional information becomes available, the Company assesses the potential liability related to its pending litigation and revises its estimates. Revisions in the Company's estimates of potential liability could materially impact its results of operations. Securities Litigation On June 8, 2012, a federal securities class action and shareholder derivative lawsuit was filed in the Eastern District of Pennsylvania alleging that the Company and its CEO aided and abetted various breaches of fiduciary duties based on the Company’s purchase of a licensing interest in a development-stage pharmaceutical program from the Genaera Liquidating Trust in May 2010 and the Company’s subsequent sale of half of its interest in the transaction to Biotechnology Value Fund, Inc. Plaintiff filed a second amended complaint in February 2015, which the Company moved to dismiss on March 20, 2015. The court has set oral argument to be held in September. The Company intends to continue to vigorously defend against the claims against the Company and its CEO. Due to the complex nature of the legal and factual issues involved, however, the outcome of the matter is not presently determinable.
