Trial Purpose
Researchers are looking for new ways to treat children with hepatoblastoma or rhabdomyosarcoma (RMS) that has relapsed or is refractory:
* Hepatoblastoma is a common liver cancer in babies and very young children
* RMS is a cancer that starts in muscle cells, often in a child’s head and neck, bladder, arms, or legs
* Relapsed means the cancer came back after treatment
* Refractory means the cancer did not respond (get smaller or go away) to treatment
The study treatment HER3-DXd (also known as MK-1022 or patritumab deruxtecan) is an antibody-drug conjugate (ADC). An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. The goals of this study are to learn:
* About the safety of HER3-DXd in children and if they tolerate it
* What happens to HER3-DXd in children’s bodies over time
* If children who receive HER3-DXd have the cancer get smaller or go away

Also called volunteer, trial participant. – usually people who have the health condition the treatment is intended to treat. In vaccine trials, the participants are usually healthy. Phase 2 trials may happen in a doctor’s office, a clinic, or a hospital.
