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 FASB 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 CEO 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. The plaintiff appealed that dismissal on September 10, 2013, and the Third Circuit reversed on October 17, 2014. The plaintiff has indicated that he intends to move to file a second amended complaint, which the Company plans to oppose within the first quarter of 2015. 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 this matter is not presently determinable. Other Litigation On June 19, 2014, a complaint was filed in California Superior Court seeking attorneys’ fees in connection with claims related to executive compensation matters described in the Company’s June 6, 2013 supplemental proxy materials. On August 1, 2014 the Company filed an answer denying all allegations in the complaint and asserting several affirmative defenses. The parties have executed a settlement agreement to resolve the matter, pursuant to which the Company is currently awaiting the dismissal of the lawsuit. Because the parties have reached agreement, the Company believes the litigation presents a remote likelihood of material loss.
