9. Commitments and Contingencies. In 2018, the Company became aware that certain patents granted to Northwestern University (which patents have been licensed by Northwestern to a third party) for a new GABA aminotransferase inhibitor were developed from CPP-115, which had previously been licensed to the Company by Northwestern. As a result, on October 26, 2018, the Company terminated the license agreement for CPP-115 and commenced an arbitration proceeding against Northwestern seeking damages for alleged breaches of the license agreement. Shortly thereafter, Northwestern filed counterclaims against the Company in the arbitration action seeking damages for alleged breaches by the Company of the license agreement. On May 21, 2019, the Company entered into a settlement agreement with Northwestern that resolved all pending disputes between the parties with no admission of liability by either party, released all claims of liability or wrongdoing between the Company and Northwestern, and dismissed the pending arbitration. Under the settlement agreement, the Company received a $100,000 payment on May 21, 2019, which is reported as income in other income, net in the consolidated statement of operations. The Company is also entitled to receive certain contingent compensation that will be reported when and if received. In May 2019, the Company became aware that the FDA had approved an NDA for Jacobus Pharmaceuticals for Ruzurgi  , their version of amifampridine (3,4-DAP) for the treatment of pediatric LEMS patients (ages 6 to under 17). On June 12, 2019, the Company announced that it had filed suit against the FDA and several related parties challenging this approval and related drug labeling. The complaint, which was filed in the federal district court for the Southern District of Florida, alleges that the FDAs approval of Ruzurgi  violated multiple provisions of FDA regulations regarding labeling, resulting in misbranding in violation of the Federal Food, Drug and Cosmetic Act (FDCA); violated the Companys statutory rights to Orphan Drug Exclusivity and New Chemical Entity Exclusivity under the FDCA, and was in multiple other respects arbitrary, capricious, and contrary to law, in violation of the Administrative Procedure Act. Among other remedies, the suit seeks an order vacating the FDAs approval of Ruzurgi  . There can be no assurance as to the outcome of this lawsuit or as to the impact of the approval of Ruzurgi  on the Companys business, financial condition or results of operations. Additionally, from time to time the Company may become involved in legal proceedings arising in the ordinary course of business. Except as set forth above, the Company believes that there is no other litigation pending at this time that could have, individually or in the aggregate, a material adverse effect on its results of operations, financial condition or cash flows.
