The combined aggregate purchase price paid to the Company for the sale, transfer, assignment and conveyance of the Company’s right, title and interest in and to aldoxorubicin and arimoclomol was $5 million, less certain transaction fees and expenses. The Royalty Agreement and the Assignment Agreement also provides for up to an additional $6 million based on regulatory and commercial milestones related to the development of arimoclomol and aldoxorubicin by their respective sponsors, Zevra, Inc. and Immunity Bio. The $6 million in potential post-closing payments is comprised of $1 million upon acceptance by the FDA of the arimoclomol New Drug Application (“NDA”), $1 million upon first commercial sale of arimoclomol, and $4 million upon FDA approval of aldoxorubicin. All royalty and milestone payments made to XOMA will be net of the existing licensing and milestone obligations owed by LadRx related to arimoclomol and aldoxorubicin. Pursuant to the Royalty Agreement, the Company agreed to sell, transfer, assign and convey to XOMA, among other payments, all royalty payments and regulatory and commercial milestone payments payable to the Company pursuant to the worldwide license agreement, dated July 27, 2017, by and between the Company and Immunity Bio, Inc.. The Royalty Agreement also provides for the sharing of certain rights with XOMA to bring any action, demand, proceeding or claim as related to receiving such payments. Management determined that the Royalty Agreement is not considered to be with a customer, and it does not fall within the scope of ASC 606. Instead, the Royalty Agreement represents an in-substance sale of nonfinancial assets, and, therefore, should be accounted for within the scope of ASC 610-20.

In January 2024, Zevra announced the FDA had accepted the NDA for arimoclomol and the Company received the one-time payment of $1 million in February 2024 recognized such net proceeds of $1.0 million as other income in the statement of operations for the period ended March 31, 2024
