Brief summary
The treatment protocol consisted of 12 mg/m2 MITO intravenous infusions every 3 months for 2 years. Dosage was adjusted according to side effects. Neurological assessment including the determination of the Expanded Disability Status Scale (EDSS) score and ophthalmologic evaluations were performed every 3 months and during relapses. Flow cytometric analysis, brain and spinal cord MRI was performed at baseline, 6, 12, 18, and 24 months.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| annual relapse rate (ARR) | one year | ARR is defined as the number of confirmed relapses in a year. The number of annual relapse rate was used as parameters of effectiveness and was compared between premitoxantrone and postmitoxantrone treatment during the follow-up period. |
| EDSS | six months | Expanded Disability Status Scale (EDSS) scores was used as parameters of effectiveness and was compared between premitoxantrone and postmitoxantrone treatment during the follow-up period. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in LVEF | six months | \- Assessment of cardiac function: Changes in LVEF by transthoracic echocardiography and determination of cardiac side effects by ECG and by measurement of CK-MB, Troponin and BNP. |
| blood cell count | three months | \- Assessment of hematological system: Monitoring blood cell count regularly. Considering marrow puncture if necessary. |
| Flow cytometric analysis | six months | Immunofluorescent staining of wholeblood samples were performed of blood drawing using antibodies against CD3/CD4/CD8/CD19/CD20/CD56 with isotype controls, followed by lysis of red blood cells and immediate acquisition and analysis by flow cytometry. |
