Sponsor: National Cancer Institute (NCI)

Sponsor score: 0

ClinicalTrials ID:NCT04616560

This clinical trial is testing a new treatment called trastuzumab deruxtecan for patients with certain types of cancer, including osteosarcoma, Wilms tumor, and desmoplastic small round cell tumor. The study aims to see if this treatment can help patients whose cancer is newly diagnosed, has returned, or hasn't responded to previous treatments.

Patient Parameters

Program Overview

This study is exploring the effects of a new cancer treatment called trastuzumab deruxtecan (DS-8201a) in patients with osteosarcoma, Wilms tumor, or desmoplastic small round cell tumor. These cancers may be newly diagnosed, have come back after treatment, or not responded to previous treatments. Trastuzumab deruxtecan is a type of medication known as an antibody-drug conjugate, which combines a targeted antibody with a chemotherapy drug to attack cancer cells more effectively.

Description

The study is divided into two phases. In Phase I, researchers will determine the safest dose of trastuzumab deruxtecan for children aged 2 to 12 with Wilms tumor or desmoplastic small round cell tumor that has returned or not responded to treatment. They will also monitor any side effects. In Phase II, the study will evaluate how well the treatment works in children and young adults with these cancers.

Participants will receive the treatment through an IV infusion every 21 days for up to 35 cycles, as long as the cancer does not progress and side effects are manageable. Throughout the study, patients will undergo various tests, including CT and MRI scans, heart function tests, and blood sample collections.

After completing the treatment, patients will have follow-up visits at 6 months to monitor their health and any long-term effects of the treatment.
