NCT03643133

Brief 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).

Outcome Measures

Primary Outcomes (1)

  • Compare event-free survival in the treatment arms

    Event-free survival defined as the time duration from randomisation to time of first event (loco-regional or distant relapse or progression, second malignancy, death from any cause)

    Expected average duration of 3 years from randomization

Secondary Outcomes (3)

  • Compare overall survival in the treatment arms

    Up to 10 years from randomization

  • Compare actual and planned cumulative dose and dose intensity of mifamurtide

    Up to 36 weeks from randomization (until end of treatment)

  • Compare the incidence of adverse events in the treatment arms

    Up to 40 weeks from randomization (4 weeks after end of treatment)

Study Arms (2)

Control arm

ACTIVE COMPARATOR

Post-operative chemotherapy alone (EI or M-API regimen depending on patient age) : M-API regimen (≤25 years) : Doxorubicin 60 mg/m², Day 1 Ifosfamide 3 g/m² Day 1 and 2 Cisplatin 100 mg/m², Day 2 EI regimen (26-50 years) : Etoposide 75 mg/m²/d, Day 1-4 Ifosfamide 3 g/m²/d, Day 1-4

Combination Product: EI or M-API regimen depending on patient age

Experimental arm

EXPERIMENTAL

Post-operative chemotherapy (EI or M-API regimen) combined with Mifamurtide 2 mg/m² twice weekly post-randomisation for 12 weeks then weekly for 24 weeks

Drug: MifamurtideCombination Product: EI or M-API regimen depending on patient age

Interventions

48 doses overall over 36 weeks

Also known as: MEPACT
Experimental arm

M-API regimen: One course of high-dose Methotrexate (optional) followed by 5 courses of API, every 21 days EI regimen : 5 course of EI, every 21 days

Control armExperimental arm

Eligibility Criteria

AgeUp to 50 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Patient with a histologically proven, confirmed by experts pathologists panel (before surgery at the latest), high-grade osteosarcoma
  • 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
  • Methotrexate-Etoposide-Ifosfamide (M-EI regimen) for patients ≤25 years
  • Doxorubicin-Cisplatin-Ifosfamide (API-AI regimen) for patients 26-50 years
  • Screening laboratory values must meet the following criteria (using CTCAE v4) and should be obtained within 7 days prior to randomisation:
  • Absolute neutrophil count ≥1.0 x 10⁹/L
  • Platelets ≥100 x 10⁹/L
  • Haemoglobin ≥8.0 g/mL
  • Alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ≤2.5 x upper limit of normal (ULN) in the absence of liver metastases or ≤5 x ULN in the presence of liver metastases
  • Total Bilirubin ≤2 x ULN (except Gilbert Syndrome: \<3.0 mg/dL) or Total Bilirubin ≤5.0 x ULN in the presence of liver metastases
  • +5 more criteria

You may not qualify if:

  • Low grade osteosarcoma, parosteal or periosteal osteosarcoma
  • Prior history of other malignancies other than study disease (except for basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix) unless the patient has been free of the disease for at least 3 years.
  • Osteosarcoma with multiple metastases for whom complete removal is not expected to be feasible even after shrinkage with chemotherapy
  • Progressive disease at any site under initial chemotherapy, confirmed before randomisation time, and not totally resected during surgery
  • Any medical condition precluding treatment with protocol chemotherapy
  • Fractional Shortening \<28% or left ventricular ejection fraction (LVEF) 50% before treatment (only for API post-operative chemotherapy) by echocardiogram or multigated acquisition (MUGA) scan
  • Pregnancy or breast-feeding
  • Hypersensitivity to the active substance or to any of the excipients
  • Concurrent use of immunodepressive treatment such as cyclosporine, tacrolimus or other calcineurin inhibitors
  • 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.
  • Patients with positive test for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS).
  • Patients with positive tests for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV RNA) indicating active or chronic infection.
