License Agreement Disclosure [Text Block] | NOTE 9 - LICENSE AGREEMENTS BRIUMVI (Ublituximab) In January 2012, the Company entered into an exclusive license agreement with LFB Biotechnologies, GTC Biotherapeutics and LFB/GTC LLC, all wholly-owned subsidiaries of LFB Group, relating to the development of ublituximab (the LFB License Agreement). Under the terms of the LFB License Agreement, the Company acquired the exclusive worldwide rights (exclusive of France/Belgium) for the development and commercialization of ublituximab. From the inception of the LFB License Agreement, the Company incurred expenses of approximately $31.0 million related to the achievement of certain milestones under the LFB License Agreement. These expenses are included in other research and development expenses in the accompanying condensed consolidated statements of operations. No further milestone payments remain payable under the LFB License Agreement. ​ LFB Group is eligible to receive royalty payments on net sales of ublituximab at a royalty rate that escalates from mid-single digits to high-single digits. The license will terminate on a country-by-country basis upon the expiration of the last licensed patent right or fifteen years after the first commercial sale of a product in such country, unless the agreement is earlier terminated (i) by LFB if the Company challenges any of the licensed patent rights, (ii) by either party due to a breach of the agreement, or (iii) by either party in the event of the insolvency of the other party. During the three and six months ended June 30, 2026, the Company recorded $24.4 million and $45.0 million, respectively, related to the worldwide royalty due under the LFB License Agreement in cost of revenue. As of June 30, 2026, $24.3 million in royalties payable under the LFB License Agreement remains outstanding in accounts payable and accrued expenses. Neuraxpharm Commercialization Agreement In July 2023, the Company entered into the Commercialization Agreement with Neuraxpharm. The Company granted Neuraxpharm the exclusive right to commercialize BRIUMVI in certain territories outside the United States, Canada, and Mexico, the commercialization rights for which had been previously retained by the Company, thus, and excluding certain Asian countries subject to previously existing partnerships. Under the terms of the Commercialization Agreement, the Company received a one-time, non-refundable payment of $140.0 million upon contract execution and a $12.5 million milestone payment upon the first key market commercial launch in the EU. The Company is eligible to receive up to an additional $492.5 million in milestone-based payments upon achievement of certain launch and commercial milestones. In addition, the Company will receive tiered double-digit royalties on net product sales up to 30%. During the three and six months ended June 30, 2026, royalty revenue of $3.6 million and $6.3 million, respectively, was recognized. The Company evaluated the Commercialization Agreement under ASC 606 and concluded that Neuraxpharm represents a customer in the transaction. In accordance with this guidance, the Company identified the following commitments under the arrangement: (i) the exclusive right to develop, sell, offer to sell and import the Product in the Territory (the License); (ii) certain development and regulatory activities (the Development and Regulatory Activities). The arrangement also provides Neuraxpharm with the right to make optional purchases of BRIUMVI (the Supply of Licensed Product). These optional purchases are accounted for as a separate contract when the right to purchase BRIUMVI is exercised. The consideration for optional purchases approximates a market-based price for BRIUMVI by Neuraxpharm in the Territory. The consideration received for optional purchases is generally received in advance of shipment and is recognized by the Company as deferred revenue until the related performance obligation is met. The performance obligation is met when control of the product passes to Neuraxpharm, at which time the optional purchases are recognized as a component of product revenue, net. As of June 30, 2026, the Company had $31.4 million of deferred revenue related to optional purchases for which the performance obligation had not been met. This includes $3.6 million recorded in accounts receivable, net for consideration the Company has an unconditional right to receive from Neuraxpharm under the Commercialization Agreement. The Company reevaluates the consideration received, and performance obligations satisfied, at the end of each reporting period. Such reevaluations may result in a change to the amount of product revenue, net, recognized and deferred revenue. Azer-cel In January 2024, the Company and its wholly-owned subsidiary, TG Cell Therapy, Inc., entered into the Precision License Agreement with Precision, pursuant to which Precision granted the Company certain exclusive and non-exclusive license rights to develop, manufacture, and commercialize Precision’s allogeneic CAR T therapy azercabtagene zapreleucel (azer-cel) for the treatment of autoimmune and other non-oncology diseases and conditions. Pursuant to the Precision License Agreement, the Company made an upfront payment to Precision of $7.5 million, consisting of (i) $5.25 million in cash and (ii) $2.25 million, as an equity investment, for the purchase of 2,920,816 shares of Precision’s common stock. In January 2025, the Company made a deferred payment of $2.5 million to Precision consisting of an equity investment in Precision’s common stock at a 100% premium to the 30-day volume-weighted average price (the 30-day VWAP) prior to purchase. In February 2026, the Company achieved the Milestone Event 1 (as defined in the Precision License Agreement) and made a one-time payment to Precision equal to $7.5 million comprised of (i) $5.25 million in cash and (ii) $2.25 million (the Milestone 1 Stock Payment), as an equity investment, for the purchase of 201,504 shares of Precision’s common stock calculated by dividing the Deferred Precision Stock Payment by 200% of the weighted average share price of the Precision common stock for the thirty (30) trading days preceding the payment date. Precision will be eligible to receive up to $286 million in additional milestone payments based on the achievement of certain clinical, regulatory, and commercial milestones. In addition, the Company is obligated to pay Precision high-single-digit to low-double-digit royalties on net sales of the licensed product on a country-by-country basis until the latest to occur of patent expiration, loss of regulatory exclusivity, and a period of ten years following the first commercial sale of the licensed product in such country. As of June 30, 2026, none of the remaining near-term clinical milestones have been achieved. MaxCyte On February 10, 2025, the Company entered into the Strategic Platform License Agreement with MaxCyte, Inc (MaxCyte), which granted a non-exclusive, non-transferable license for the Company to use MaxCyte’s cell loading technology (licensed technology) to develop and commercialize products for the treatment of autoimmune and other non-oncology diseases and conditions, including azer-cel, licensed by the Company from Precision in January 2024. MaxCyte is eligible to receive royalty payments on net sales of approved products developed with the licensed technology at a royalty rate in the low-single digits. Upon the achievement of the first dosing of a human subject in a pivotal trial for a product developed with the licensed technology the Company will make a $1.0 million payment to MaxCyte. MaxCyte is also eligible to receive up to $13.0 million in additional milestone payments based on the achievement of certain regulatory and marketing approvals. The Company is required to pay an annual licensing fee of approximately $0.2 million for access to the licensed technology. The Strategic Platform License Agreement expires on the ten-year anniversary unless the Company achieves at least one of the milestone events prior to that date. The Company has the option, at its sole discretion, to extend the term of the Strategic Platform License Agreement beyond the initial ten years for successive renewal terms of five years each, as long as all applicable licensing fees and milestone payments are paid timely and the Company provides MaxCyte at least ninety days written notice prior to the expiration of the then-current term.
