Curis will be obligated to continue development of CUDC-907 following the term of this agreement, provided that study results are positive and that there is a regulatory path forward and would be required to make a payment to LLS if it did not continue development in this success scenario. In the event that future studies of CUDC-907 are unsuccessful, the funding received from LLS would be treated as a non-refundable grant to Curis. Assuming that Curis licenses or partners CUDC-907 in B-cell lymphoma or multiple myeloma, or, in the event that Curis commercializes the drug candidate itself in these indications, Curis would be obligated to pay LLS future milestones of up to 2.5 times the funding amounts received from LLS under the agreement, primarily upon meeting defined regulatory submission, approval and commercialization objectives.About The Leukemia & Lymphoma Society The Leukemia & Lymphoma Society ® (LLS) is the world's largest voluntary health agency dedicated to blood cancer.
