Summary

Trial evaluating the impact on efficacy of mifamurtide as add-on treatment to post-operative chemotherapy compared to post-operative chemotherapy alone in first-line treatment of patients with high-risk osteosarcoma (defined as metastatic osteosarcoma at diagnosis or localised osteosarcoma with poor histological response).

Description

Multicentre, randomised, open-label, phase II trial, with 2 parallel groups. After pre-operative chemotherapy and surgery of the primary tumour and lung metastases (if applicable), patients presenting high-risk osteosarcoma (defined as metastatic osteosarcoma at diagnosis or localised osteosarcoma with poor histological response) will be randomised between 2 arms:

  • Control arm: post-operative chemotherapy alone (with regimens adapted to the age of patient)
  • Experimental arm : post-operative chemotherapy combined with mifamurtide

This randomised trial is part of a study recruiting all patients 50 years old with a newly diagnosed high-grade osteosarcoma.

Details
Condition Osteosarcoma
Treatment Mifamurtide, EI or M-API regimen depending on patient age

Registered at diagnosis into the study
Primary tumour resected after pre-operative chemotherapy
Osteosarcoma classified as high risk because of at least one risk factor
presence of distant metastases or skip metastases at diagnosis
and/or poor histological response to pre-operative chemotherapy (>10% residual viable cells on the analysis of the primary tumour surgical specimen)
Pre-operative chemotherapy combining

Exclusion Criteria

Concurrent use with high-dose non-steroidal anti-inflammatory drugs (NSAIDs, cyclooxygenase inhibitors)
Inflammatory or auto-immune disease, allergy or asthma requiring a chronic use of steroid treatment that cannot be stopped
