Litigation 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 against Genaera Corporation and its officers, directors, major shareholders and trustee ("Genaera Defendants") for allegedly breaching their fiduciary duties to Genaera shareholders. The lawsuit also names the Company and its Chief Executive Officer John Higgins as additional defendants for allegedly aiding and abetting the Genaera Defendants' various breaches of fiduciary duties based on the Company's purchase of a licensing interest in a development-stage pharmaceutical drug 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. Following an amendment to the complaint and a round of motions to dismiss, the court dismissed the amended complaint with prejudice on August 12, 2013. Plaintiff appealed that dismissal on September 10, 2013. Briefing is now complete, and the parties are awaiting the scheduling of oral argument before the Third Circuit, which management anticipates will take place in the next few months. Management believes it is very likely to prevail on appeal, and, for that reason, believes the litigation presents a remote likelihood of material loss. Other Litigation On June 19, 2014, a complaint seeking attorneys’ fees in connection with claims related to executive compensation matters described in the Company’s June 6, 2013 supplemental proxy materials was filed in California Superior Court. Management believes the fees demanded by plaintiffs’ counsel are excessive and intends to defend itself vigorously in the litigation. Due to the complex nature of the legal and factual issues involved, however, the outcome of this matter is not presently determinable.
