License, Collaboration, and Funding Agreements	LICENSE, COLLABORATION AND FUNDING AGREEMENTS Research and Development Incentive Program The Company participates in a research and development incentive program provided by the Austrian government whereby the Company is entitled to reimbursement by the Austrian government for a percentage of qualifying research and development expenses and capital expenditures incurred by the Company’s subsidiary in Austria. As of March 31, 2024, the amount due under the program is $0.7 million, which amount is included in research and development incentive receivable in the condensed consolidated balance sheet. During the three months ended March 31, 2024 and 2023, the Company recorded $0.2 million and $0.1 million of income related to the program within the condensed consolidated statements of operations and comprehensive loss as other income. License and Collaboration Agreements In July 2014, the Company entered into a license agreement with Genzyme (the “Genzyme Agreement”) pursuant to which the Company was granted an exclusive license to certain patents and intellectual property owned or controlled by Genzyme related to the CXCR4 receptor to develop and commercialize products containing licensed compounds (including but not limited to mavorixafor) for all therapeutic, prophylactic and diagnostic uses, with the exception of autologous and allogenic human stem cell therapy. Under the terms of the Genzyme Agreement, the Company is obligated to use commercially reasonable efforts to develop and commercialize licensed products for use in the field in the United States and at least one other major market country. The Company has the right to grant sublicenses of the licensed rights that cover mavorixafor to third parties. As of March 31, 2024, the Company is obligated to make future milestone payments in the aggregate amount of up to $20.0 million, contingent upon the achievement by the Company of certain clinical-stage regulatory and sales milestones with respect to licensed products. A $7.0 million regulatory milestone became payable 30 days following the Company’s receipt of FDA approval of the Company’s NDA on April 26, 2024. The remaining regulatory milestones include (i) $3.0 million for the acceptance by the European Medicines Agency (“EMA”) of the Company’s first drug application and (ii) $5.0 million upon the notification by the EMA of regulatory approval of the Company’s first drug application. The Company must also make one-time sales milestone payments of $0.5 million, $1.5 million and $3.0 million on cumulative net sales of $50.0 million, $150.0 million and $300.0 million, respectively. The Company is also obligated to pay Genzyme tiered royalties based on net sales of licensed products that the Company commercializes under the agreement. Upon the first sale of the Company’s drug product in the U.S., the Company will incur a royalty on annual net sales at a rate of 6% up to $150 million, 10% on the portion of annual net sales between $150 million and $300 million, and 12% thereafter on annual sale over $300 million. The Company will include these royalties in cost of goods sold. There were no material modifications of the Company’s license or collaboration agreements during the three months ended March 31, 2024.
