Summary

A phase 2 study of regorafenib in combination with nivolumab in patients with refractory or recurrent osteosarcoma.

Description

This is a single arm, Simon two-stage historically controlled study to compare the 4 month progression-free survival rate of patients with relapsed/refractory osteosarcoma treated with regorafenib in combination with nivolumab to those who received regorafenib alone (historical control).

Details
Condition Osteosarcoma, Osteosarcoma in Children, Osteosarcoma Recurrent, Osteosarcoma Metastatic
Treatment Nivolumab, Regorafenib 40 MG, Regorafenib 20MG
Clinical Study IdentifierNCT04803877
SponsorSarcoma Alliance for Research through Collaboration

Myelosuppressive chemotherapy: Patients must not have received myelosuppressive
chemotherapy within 3 weeks of enrollment
Hematopoietic growth factors: At least 7 days must have elapsed since the completion
of therapy with a white blood cell or platelet growth factor. At least 14 days must
have elapsed after receiving pegfilgrastim

included a monoclonal antibody (e.g., dinutuximab, denosumab, bevacizumab)
Radiotherapy: ≥ 2 weeks must have elapsed since local palliative XRT (small port); ≥ 3
months must have elapsed if prior craniospinal XRT was received, if ≥ 50% of the
pelvis was irradiated, or if TBI was received; ≥ 6 weeks must have elapsed if other
substantial bone marrow irradiation was given
