Summary

This trial is to find out the benefits and side effects of magrolimab and dinutuximab for treating patients with relapsed neuroblastoma or relapsed osteosarcoma. Magrolimab and dinutuximab are monoclonal antibodies that may interfere with the ability of tumor cells to grow and spread. The combination of magrolimab and dinutuximab may shrink or stabilize relapsed or refractory neuroblastoma or relapsed osteosarcoma.

Who is the study for?
This trial is for patients with neuroblastoma or osteosarcoma that has returned or isn't responding to treatment. It's open to various ages, depending on the arm of the study (up to 18 years for Arm A and up to 35 years for Arm B). Participants need a certain level of physical fitness, adequate organ function, and cannot be pregnant. They must not have had certain treatments recently and agree to use contraception.
What is being tested?
Researchers are testing magrolimab combined with dinutuximab in this phase I trial. These drugs are designed to stop tumor cells from growing and spreading. The goal is to find the safest dose that might also shrink or stabilize cancer in patients who've had surgery or whose disease has come back after previous treatments.
What are the potential side effects?
Possible side effects include reactions related to the immune system attacking normal organs (due to monoclonal antibodies), infusion-related reactions, fatigue, blood disorders like anemia, increased risk of infections, and potential allergic responses similar in nature to other compounds used in this study.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Arm B (magrolimab, dinutuximab, surgery)Experimental Treatment8 Interventions
Patients receive magrolimab IV and dinutuximab IV on study. Patients with pulmonary osteosarcoma may undergo surgical resection of tumor after cycle 1. After surgery, these patients continue receiving magrolimab and dinutuximab on study. Patients also undergo CT, MRI, and collection of blood samples on study, as well as bone marrow aspiration and biopsy throughout the trial.
Group II: Arm A (magrolimab, dinutuximab)Experimental Treatment7 Interventions
Patients receive magrolimab IV and dinutuximab IV on study. Patients also undergo CT, MRI, and blood sample collection on study, as well as bone marrow aspiration and biopsy throughout the trial.
