About

This study will primarily address the question whether the combination of Mitoxantrone therapy with dexrazoxane can reduce cardiotoxic side effects in the treatment of Multiple Sclerosis patients in comparison to Mitoxantrone monotherapy.

Full description

It is designed to provide clinical and paraclinical efficacy and safety data for dexrazoxane in Mitoxantrone treatment of Multiple Sclerosis in order to investigate the possible positive influence of dexrazoxane on cardiac function of Mitoxantrone-affected myocardial tissue and on the possible augmented clinical efficacy of Mitoxantrone in combination with dexrazoxane on neurological outcome parameters. The incidence of cardiotoxicity during combined Mitoxantrone/dexrazoxane treatment will be investigated and compared to the standard Mitoxantrone-treatment without dexrazoxane.

Inclusion criteria

Written informed consent to participate in the study
Male or female subject is 18 years of age to 55 years of age
Subject must have one of the below mentioned confirmed diagnoses of Multiple Sclerosis: RRMS or CPMS according to rev. McDonald Criteria (2005)
If female of childbearing potential: Will to practice reliable birth control measures during study treatment and for at least 6 months after completion of study medication; not lactating or pregnant; and has a documented negative pregnancy test result within 72 hours prior to study medication administration. Male study participants: Will to practice reliable birth control measures during study treatment and for at least 6 months after completion of study medication
Subject is willing to participate in the study, follow protocol study treatment regimen, and comply with all planned assessments
Mitoxantrone treatment indication is given according to current guidelines:
- Relapsing progressive or secondary progressive MS with/without superimposed relapses
- EDSS 3-6; EDSS deterioration ≥1 point over last 18 months or 2 relapses
- non-response or non-tolerability of pre-treatment
≥ 48 mg/m² BSA MX dose received up to baseline visit as lifetime dosage before study entry. If the patient is under regular ongoing MX treatment, the infusion interval of 3 months must be obtained (see exclusion criteria)

Exclusion criteria

Concomitant clinically suspected or confirmed neurologic disorder at study entry that may interfere with the evaluation in this protocol [i.e. EDSS, MSFC, MEP or MRI measurements]
Pre-Treatment with DRZ or immunosuppressive drugs of the anthracycline family with cardiotoxic potential other than MX prior to study enrollment
Last Treatment with MX within the past 84 days prior to study enrollment (regular 3-monthly intervals must be obtained)
History of hypersensitivity to any of the study drugs or to drugs with similar chemical structures
Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive HCG laboratory test (>5 mIU/ml)
Unwillingness to perform adequate contraception
Use of other investigational drugs at the time of enrollment, or within 30 days or 5 half-lives of enrollment, whichever is longer
Subjects unable or unwilling to adhere to the study-designated procedures and restrictions
Patients not able to perform cardiac/neurological investigations including MRI, e.g. hypersensitivity to MRI contrast agent
Other known contraindication for DRZ or MX according to current labelling
Subject has a pre-existing cardiac disease interfering with left ventricular ejection fraction, i.e. cardiac insufficience for different reasons (resulting from prior cardial conditions such as myocardial infarction, myocarditis)
Routine co-administration of cortisone-pulse therapy (other than for treatment of relapses), intrathecal triamcinolone-therapy or other off-label/ investigational agents (e.g. fampridine, aminopyridine)
History of malignancy in the past 5 years (excluding localized basal cell carcinoma of the skin)
Pre-Treatment with other immunosuppressive drugs (azathioprine, methotrexate, mycophenolate, cyclophosphamide) within the past 3 months
Pre-Treatment with monoclonal antibodies (natalizumab, rituximab) within the past 6 months
