Additional Relevant Details As part of the license, Athersys will receive an initial license fee of $15 million, as well as have the opportunity to earn milestone and royalty payments upon the successful accomplishment of specific development and commercialization objectives, including the achievement of certain sales milestones. Development and approval milestones for stroke could total $30 million, in addition to sales milestones that could reach $185 million based on successful commercialization and the achievement of substantial sales of an approved product for treating stroke in Japan. Athersys will also receive tiered, double-digit royalties increasing into the high teens on product sales and will be responsible for providing manufactured product to Healios, subject to receiving reimbursement under a manufacturing supply arrangement. Furthermore, if Healios elects to expand the partnership following the successful completion of Athersys' ongoing clinical trial in ARDS, Athersys will receive a license expansion fee of $10 million for the exclusive rights to two additional indications in Japan, with the corresponding potential for further milestones based on successful achievement of specific development and commercialization objectives. As part of the expanded alliance, Healios will also have the right to incorporate Athersys technology in other organ bud indications.
