Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects in the treatment group will receive three 300mg natalizumab infusions occurring once every 4 weeks flexibly (either at home or in a workplace) from a Tysabri Australasian Prescribing Program (TAPP) trained ambulatory care nurse (level 3 RN). After three infusions in Phase 1 (lasting three months), subjects will cross over to the control group in Phase 2 and receive usual care for another three infusions (lasting three months). Crossover will therefore occur between the third and fourth infusions.

Comparator / control treatment
Subjects in the control group will receive usual care comprising three 300mg natalizumab infusions occurring once every 4 weeks in a hospital ambulatory day care unit by an infusion nurse. After three infusions in Phase 1 (lasting three months), subjects will cross over to the treatment group in Phase 2 and receive flexible delivery for another three infusions (lasting three months). Crossover will therefore occur between the third and fourth infusions.
Control group
Active

Outcomes
Primary outcome [1] 298175 0
Adverse events (number, severity, treatment patterns and patient outcomes) collected by nurses administering natalizumab infusions and self reported by patients. Known common adverse events include: headache, fever and chills, back pain, fatigue, rigors, nausea and localized or multi-symptomatic hypersensitivity reactions. These would be criteria for stopping the infusion if the patient has NOT experienced them before & seeking guidance from the consultant neurologist. More concerning adverse events that require immediate intervention and would require anaphylaxis management have symptoms including itching, dizziness, fever, rash, nausea, flushing, breathing trouble, and chest pain.
Timepoint [1] 298175 0
For both intervention and control groups, monitoring for adverse events by nurses will occur during the infusion and for one hour post-infusion. Patients will be able to record adverse events occurring outside of these times using a patient diary.
Secondary outcome [1] 323378 0
Infections (a composite outcome comprising number; type, including whether hospital acquired; treatment) recorded by both patients and nurses administering natalizumab.
Timepoint [1] 323378 0
For both intervention and control groups, monitoring for will occur during the monthly infusion. Patients will be able to record infections occurring outside of these times using a patient diary.
Secondary outcome [2] 323379 0
Patient satisfaction with their treatment using the ‘Treatment Satisfaction Questionnaire for Medication’ (TSQM)’
Timepoint [2] 323379 0
Patient satisfaction will be measured at the end of phase 1 (at 3 months) and phase 2 (at 6 months) in both study arms.
Secondary outcome [3] 323380 0
Quality of life using the MS Quality of Life Inventory (MSQLI) a battery of measurements consisting of 10 individual scales providing a quality of life measure that is both generic and MS-specific.
Timepoint [3] 323380 0

Intervention assignment
Crossover
Other design features
The study will test for equivalence in the delivery of natalizumab flexibly and at hospital outpatients department. The goal of an equivalence study is to demonstrate equivalency between two treatments, i.e. that the efficacies of two treatments are close enough so that one cannot be considered superior or inferior. Therefore, in equivalence studies, the null hypothesis is that the two treatments are not equivalent, and if the null hypothesis is rejected, the alternate hypothesis of equivalence between the two treatments is supported.

Statistical methods / analysis
In general, the analysis will be based on within-subjects comparisons between the two study time periods, as all participants will be exposed to both the control and intervention.
The analysis will include tests for confounding due to treatment effects or period effects to rule out a carryover effect (i.e. the washout phase between A/B and B/A was not long enough).

Depending on the frequency of events, variables measured by counts (adverse drug events) may be analysed as continuous data, Poisson-distributed count data or dichotomous data. For continuous and Poisson distributions, t-tests will be used, in the latter chi-square tests would be used. The treatment adherence will be tested using a comparison of proportions.

Outcomes that are measured before (‘pre’) and after (‘post’) each phase (i.e. quality of life via MSQLI and EDSS) the differences between pre-post measures will be calculated and compared between treatment and control interventions using univariable analysis (eg t-tests). Multivariable analysis adjusting for potential co-variates based on patient demographics (eg age, gender, length and severity of the disease) will also be conducted.

For continuous outcomes (e.g. satisfaction scores) that are measured only once at the end of each phase, unpaired t-tests will be conducted on the within subject differences.

The significance level will be set at a=0.05.

Summary
Brief summary
In some countries (eg Canada and UK), some patients can receive monoclonal antibody (MAB) treatment at home, under the supervision of an appropriately trained registered nurse. However, we are not aware of any comparable studies examining the safety of natalizumab and flexible delivery (i.e. treatment at home, or in a community setting) for people with multiple sclerosis (MS).

Therefore, the broad objective of this study is to investigate the flexible delivery of natalizumab. In many cases, it is anticipated that flexible delivery will entail delivery in the patient’s own home. The study will compare the flexible delivery of natalizumab with usual care (attendance in an outpatient department) and answer whether it is acceptable to patients, is effective and safe, and is cost effective. The study will comprise a pilot study to better understand feasibility and safety, and to inform a larger, proposed full-scale study.

The primary objective of the study is to determine whether the flexible delivery of natalizumab is safe for people with MS. The additional objectives of this study in this study population are as follows:
(a) Is the flexible delivery of natalizumab acceptable to patients and healthcare staff?
(b) Is the flexible delivery of natalizumab as effective in treating symptoms?
(c) Is the flexible delivery of natalizumab cost effective?
