Comparing the Safety and Benefit of Natalizumab (Tysabri®) At-home Infusion vs At-hospital Infusion in Multiple Sclerosis

Active, not recruiting
Conditions
Multiple Sclerosis (MS)
Registration Number
NCT04777539
Lead Sponsor
Nantes University Hospital
Brief Summary

At-home use of Natalizumab in multiple sclerosis (MS) patients has been temporarily granted by French security agency of medicines and Health products (ANSM). The main objective of the study is to compare the safety of natalizumab administration at home vs at hospital based on retrospective and prospective data collection. Quality of life, patient perception of at-home natalizumab administration are also evaluated as secondary objectives as well as medico-economic assessment of the method.

Data will be collected for a 12-month retrospective period and a 12-month prospective period.

Detailed Description

As part of the Covid-19 pandemic, some neurologists have alerted the French authorities (ANSM: National Medicines Safety Agency) to the interruption of natalizumab treatment by some MS patients. The ANSM has granted temporary home use of natalizumab within the framework of a "at-home hospitalization" (HAD) program. The study purpose is to assess at-home natalizumab administration regarding safety, disease activity, quality of life, patient's perception and costs by comparing outcomes before and after "At Home" natalizumab treatment strategy.

The study consists of two periods of observation: a retrospective one corresponding to the year prior the study entry and a prospective one corresponding to patient follow-up for one year from the date of the patient inclusion. The date of the inclusion corresponds to the natalizumab-infusion conducted at hospital just before infusions hospital at-home started. Retrospective data are collected from medical record and a minimal dataset is needed to enroll the patient regarding MRI activity and safety data (i.e., nature and number of SAE and selected AE of grade 2 the year prior study entry).

The prospective period consists of 10 at-home natalizumab infusions (months 1-5 and 7-11) and 3 at-hospital natalizumab infusions (inclusion, months 6 and 12) according to standard care. In addition to clinical, MRI and safety (SAE and selected AE of grade 2) data collected as part of standard medical care from medical record over all the study period, Quality of life (EQ-5D-5L, MusiQol) and patient's preference (Musicare) questionnaires will be administered at inclusion and months 6 and 12 and clinical global impression of change will be recorded at month 6 and 12. Patients will be asked to notify any adverse events that may occur between each at-home infusion and to record each month his/her healthcare resource consumption in a diary. Patients will be contacted each month after at-home infusion to record safety and healthcare resource consumption data.

For a sub-group of 15 patients qualitative interview will be performed between month 3 and 8 as part of patient preference assessment.

Micro-costing dedicated forms and experts' statements will be used to assess resource utilization associated to natalizumab infusion during each period for medico-analyze purpose.

Primary Outcome Measures
NameTimeMethod
Number of serious Adverse events (SAE) and selected adverse events (AEs) of grade 2One year after enrollment

Grades are based on CTCAE V5. Selected AEs of grade 2: myocarditis, pericarditis, diarrhea, enterocolitis, esophagitis, mucositis, fever/hypothermia folicullitis, papular and/or pustular rash, herpes zoster.

Secondary Outcome Measures
NameTimeMethod
Patient experienceOne point per patient between months 3 and 8

Semi-structured interview based on " patient tracer " model will be conducted in a sub-group of 15 patients.

Change from baseline in gadolinium positive lesion as assessed by MRIBaseline and 12 month before and 12 month after enrollment

Modification is based percentage of patient with at least one Gd-enhancing lesion

Multiple Sclerosis International quality of Life (MusiQoL)Baseline and months 6 and 12

MusiQoL is a self-administered disease-specific quality of life instrument that comprises 31 items encompassing 9 dimensions: activities of daily living (8), psychological well-being (4), symptoms (3), relationships with friend (4), relationships with family (3), relationship with healthcare system (3), sentimental and sexual life (2), coping (2) and rejection (2). Each item is answered using a 6-point Likert scale (Never/Not at all, Rarely/A little, Sometimes/Somewhat, Often/A lot, Always/Very much and Not applicable)

MusicareBaseline and months 6 and 12

Musicare is a self-administered disease-specific instrument investigating experience of the quality of care for MS. It comprises 35 items encompassing 5 domains: Information about the disease (11), Information about the treatments/medical investigation (8), Relationships with health care teams (8) Health care access (5) Reception in care structures (3).

Annualized Relapse RateTwo time points per patient one year prior to and one year after enrollment

Annualized Relapse Rate

Change from baseline in T2 lesion load as assessed by MRI12-month (+/-6 month) prior enrollment, Baseline (enrollment+/-3 months), 12 months after enrollment

Modification is based on percentage of patient with at least one new T2 lesion

EuroQol-5Dimension 5Level (EQ-5D-5L)Baseline and months 6 and 12

The EQ-5D-5L is a self-administered instrument consisting in 2 components that describe patient's health state:

A five dimensional questionnaire describing health in terms of mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Patient is asked to indicate for each one the level of functioning: no problems, slight problems, moderate problems, severe problems and extreme problems.

A visual analogue scale (VAS) that measures health state (from 0 to 100).

Clinical Global impressions of improvement (CGI-I)Months 6 and 12

The CGI is a generic 3-component scale used over the years in a broad range of diseases. The CGI-I (Improvement) is one of the components (one item) measuring change in health state since the entry in the study and can be rated independently.

CGI-I is rated on a 7-point scale: from 1 (very much improved) to 7 (very much worse).

The average cost per patientDuring study, it will be evaluated the average cost per patient for one year of treatment (comparison HDJ vs HAD)
