A PIP outlines a pharmaceutical company’s strategy for investigation of the new medicinal product in the pediatric population and is a required submission as part of the regulatory process for the registration of new medicines in Europe. An approved PIP is a prerequisite for filing a Marketing Authorization Application ("MAA") for any new medicinal product in Europe.

Researchers at Memorial Sloan Kettering Cancer Center ("MSK") developed DANYELZA, which is exclusively licensed by MSK to Y-mAbs. MSK has institutional financial interests related to the compound and Y-mAbs.
