In Israel, DANYELZA is expected to be commercialized by Takeda Israel, under the exclusive license and distribution agreement entered in 2020 between Takeda Israel and the Company.

"The regulatory approval of DANYELZA in Israel represents our first marketing authorization outside of the U.S. and is a milestone for our collaboration with Takeda and more importantly for the pediatric patients we are dedicated to serving," said Thomas Gad, President, and Interim Chief Executive Officer. "The approval in Israel further demonstrates our commitment to expanding the reach of our commercial stage products internationally to patients with unmet medical needs."

"We are extremely excited by the approval of DANYELZA in Israel," said Arie Kramer, General Manager of Takeda Israel. "This registration, following the expedited reimbursement of the product last December by the Israeli Ministry of Health, allowing Takeda and Y-mAbs to offer a new innovative treatment for pediatric neuroblastoma patients in Israel, is in alignment with Takeda’s vision of Better Health and Brighter Future to every patient in the world."

Researchers at Memorial Sloan Kettering Cancer Center ("MSK") developed DANYELZA, which is exclusively licensed by MSK to Y-mAbs. As a result of this licensing arrangement, MSK has institutional financial interests in the compound.
