A Phase II Study of Trastuzumab Deruxtecan (DS-8201A) in Adolescents and Young Adults with Recurrent HER2-Positive Osteosarcoma


Full Title

A Phase 2 Study of DS-8201a (NSC#807708, IND#153036) in Adolescents, or Young Adults with Recurrent HER2+ Osteosarcoma (PEPN1924)(CIRB)


This study is assessing the safety and effectiveness of the investigational drug trastuzumab deruxtecan (DS-8201A) in adolescents and young adults with osteosarcoma (bone cancer) that is positive for the HER2 protein and has come back after prior treatment. Trastuzumab deruxtecan includes an antibody (trastuzumab) linked to a chemotherapy drug (deruxtecan). Trastuzumab attaches to HER2-positive cancer cells in a targeted way and delivers deruxtecan to kill them. The treatment is given intravenously (by vein).

  • Patients should recover from the serious side effects of prior therapies before receiving trastuzumab deruxtecan.
  • Patients must be physically well enough that they are fully ambulatory, capable of all self-care, and capable of all but physically strenuous activities. As an example, patients must be well enough that they would be able to carry out office work or light housework.
  • This study is for patients ages 12-39.
