Efficacy and Safety of Mitoxantrone in Patients With Refractory Neuromyelitis Optica and Spectrum Disorders

December 19, 2013 updated by: Xuanwu Hospital, Beijing
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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 51 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: MITO, annual relapse rate, safety
For refractory NMO patients aged 18-55, the initial dose 12 mg/m2 mitoxantrone was administered over a five day course every 3 months for 2 years (a total of eight courses). The initial dose was reduced to 9 mg/m2 if the preinfusion white-blood-cell count was 3.0-3.99 ×109/L,and to 6 mg/m2 if the white-blood-cell count was 2.0-2.99 ×109/L. No infusion if the white-blood-cell count was less than 2.0×109/L. The initial dose was reduced to 10 mg/m2 for nonhaematological toxic effects of WHO grade 2-3. Subsequent dose after 3 month was reduced to 10 mg/m2 for infections that occurred within 3 weeks of a previous infusion accompanied by a white-blood-cell count below 2×109/L, or to 8 mg/m2 for infections accompanied by white-blood-cell count of less than 1×109/L.
Drug: Mitoxantrone
The treatment protocol consisted of 12 mg/m2 MITO intravenous infusions every 3 months for 2 years. Dosage was adjusted according to side effects.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
annual relapse rate (ARR)
Time Frame: 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.
one year
EDSS
Time Frame: 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.
six months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in LVEF
Time Frame: 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.
six months
blood cell count
Time Frame: three months
- Assessment of hematological system: Monitoring blood cell count regularly. Considering marrow puncture if necessary.
three months
Flow cytometric analysis
Time Frame: 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.
