Study information
Scientific title
A Mechanistic Study Of Mifamurtide (MTPPE) In Patients With Metastatic And/Or Recurrent Osteosarcoma
Acronym
MEMOS: a Eurosarc Study of Mifamurtide in advanced osteosarcoma
Study hypothesis
This is a Bayesian designed multi-arm, multi-centre open-label phase II study in patients with metastatic and/or recurrent osteosarcoma, which will investigate why some patients with osteosarcoma may respond better than others to mifamurtide given alone or in combination with ifosfamide.

Condition
Topic: Cancer; Subtopic: Sarcoma; Disease: Bone
Intervention
Patients with relapsed or metastatic osteosarcoma will be divided into three treatment groups (Arms). Depending on their current disease status, patients may be either Registered to Arm A (resectable group), to receive Mifamurtide alone; or Randomised to Arm B/C (non-resectable group), to receive mifamurtide in combination with ifosfamide.
Arm A - Mifamurtide alone; Arm B - Ifosfamide alone for 6 weeks then Ifosfamide + mifamurtide for 6 weeks, then mifamurtide alone for 30 weeks; Arm C - Ifosfamide + mifamurtide for 12 weeks then mifamurtide alone for 24 weeks. All participants will receive 36 weeks or more of mifamurtide.
Biopsies (or resected tumour samples) will be obtained before and after 6 weeks of therapy interval in order to determine the pharmacodynamic endpoints. The target sample size is 40 patients. An interim analysis will be performed for the primary efficacy endpoint.

Participant exclusion criteria
1. Pregnant or breastfeeding woman. Men or women of childbearing potential unless effective methods of contraception are used during study treatment and for at least 7 days after the last mifamurtide dose.
2. Previous treatment with mifamurtide or a mifamurtide like drug* in a clinical trial setting for the treatment of metastatic and/or recurrent osteosarcoma in the six months prior to registration.
3. Contraindications to lung biopsies
4. Hypersensitivity to ifosfamide or any component of the formulation.
5. Previously diagnosed brain metastases.
6. Significant active cardiac disease including: uncontrolled high blood pressure (no greater than 2 standard deviations above the mean for age for systolic blood pressure (SBP) and diastolic blood pressure (DBP), unstable angina, congestive heart failure, myocardial infarction within the previous 6 months, or serious cardiac arrhythmias and with a history of pericarditis and myocarditis
7. Treatment with any other investigational agent, or participation in another interventional clinical trial within 21
days prior to enrolment.
8. Major surgery within 21 days prior first study biopsy
9. Currently taking of high-dose nonsteroidal antiinflammatory drugs (NSAIDs) or corticosteroid treatment
10. Concurrent use of ciclosporin or other calcineurin inhibitors.
11. Any psychological, social or medical condition, physical examination finding or a laboratory abnormality that the Investigator considers would make the patient a poor trial candidate or could interfere with protocol compliance or the interpretation of trial results.
12. Any other active malignancy, with the exception of adequately treated conebiopsied in situ carcinoma of the
cervix uteri and non-melanoma skin lesions.
13. Patients who are known to be serologically positive for Hepatitis B, Hepatitis C or HIV.
* mifamurtide-like drugs include GMCSF, interferon and other macrophage activating molecules.
