Study Details

Study Description

Brief Summary

Currently, no study has addressed real-life data describing changes in health resource consumption and related costs attributable to mepolizumab treatment. The aim of the current study is to fill this knowledge gap by performing an exhaustive extraction of data for patients receiving mepolizumab in the French single-payer health care system. The change in real-life health-resource usage and costs observed for these patients would provide the first evidence that mepolizumab is changing the care landscape for eligible severe asthma patients.

The overall objectives of this study are: (i) using the SNDS French national database, to identify a representative, nation-wide population of patients treated with mepolizumab with a follow-up period of at least 12 months, (ii) to describe the initial one-year changes in health resource use before and after the initiation of mepolizumab treatment and (iii) to estimate the change in associated costs for the first year of treatment. These initial data will additionally serve as a basis for the design of longer-term studies.

Primary objective: To estimate the change in associated costs for the first year of treatment

Condition or Disease Intervention/Treatment Phase

Detailed Description

Secondary objectives:
  • To describe the initial one-year changes in health resource use before and after the initiation of mepolizumab treatment

  • To further characterize rates of change in health resource usage and/or costs in subpopulations of interest (sex, age groups, severe asthma, uncontrolled asthma, COPD, diabetes)

This retrospective, non-interventional (not involving human subjects) database study will compare real-life patient health resource consumption before versus after a first injection of mepolizumab. Data concerning patients receiving mepolizumab will be collated for a 12-month period (the "baseline period") preceding a first index treatment (at "T0") and compared to a 12-month period occurring after the index treatment (the "exposure period").

Arms and Interventions

Arm Intervention/Treatment
The study population

The study population will comport all beneficiaries in the national French SNDS database who were prescribed mepolizumab and for whom health resource use data is available for the 12 months preceding and following a first filled prescription for mepolizumab.

Drug: Mepolizumab
The first administration of mepolizumab.

Outcome Measures

Primary Outcome Measures

  1. The change in total health care costs for the year preceding the initiation of mepolizumab versus for the year after. [-12 months versus +12 months]

    Cumulative per-beneficiary costs (including all health care resource uses and government benefits) will be described and contrasted between the baseline and exposure periods. Day 0 = the initiation of mepolizumab treatment.

Secondary Outcome Measures

  1. Change in drug consumption: mepolizumab [-12 months versus +12 months]

    Drug consumption refers to the quantity of medication consumed.

  2. Change in drug consumption: corticosteroids [-12 months versus +12 months]

    Drug consumption refers to the quantity of medication consumed.

  3. Change in drug consumption: asthma-specific medications [-12 months versus +12 months]

    Drug consumption refers to the quantity of medication consumed.

  4. Change in drug consumption: diabetes-related medications [-12 months versus +12 months]

    Drug consumption refers to the quantity of medication consumed.

  5. Change in the number of hospitalisations: all causes [-12 months versus +12 months]

  6. Change in the number of hospitalisations: asthma-related [-12 months versus +12 months]

  7. Change in the cumulative number of days of hospitalisation: all causes [-12 months versus +12 months]

  8. Change in the cumulative number of days of hospitalisation: asthma-related [-12 months versus +12 months]

  9. Change in the cumulative number of days of intensive care: all causes [-12 months versus +12 months]

  10. Change in the cumulative number of days of intensive care: asthma-related [-12 months versus +12 months]

  11. Change in the number of generalist consults [-12 months versus +12 months]

    The cumulative numbers of consultations will be compared between the baseline and exposure period and differentiated according to type (general and specialist medical consults, nursing and other paramedical consults etc). Special attention will be given to pulmonology/allergology and metabolic/endocrine specialist consults, as well as nursing consults for injections.

  12. Change in the number of specialist consults [-12 months versus +12 months]

    The cumulative numbers of consultations will be compared between the baseline and exposure period and differentiated according to type (general and specialist medical consults, nursing and other paramedical consults etc). Special attention will be given to pulmonology/allergology and metabolic/endocrine specialist consults, as well as nursing consults for injections.

  13. Change in the number of nursing consults [-12 months versus +12 months]

    The cumulative numbers of consultations will be compared between the baseline and exposure period and differentiated according to type (general and specialist medical consults, nursing and other paramedical consults etc). Special attention will be given to pulmonology/allergology and metabolic/endocrine specialist consults, as well as nursing consults for injections.

  14. Change in the number of other paramedical consults [-12 months versus +12 months]

    The cumulative numbers of consultations will be compared between the baseline and exposure period and differentiated according to type (general and specialist medical consults, nursing and other paramedical consults etc). Special attention will be given to pulmonology/allergology and metabolic/endocrine specialist consults, as well as nursing consults for injections.

  15. Change in the number of lung function assessments [-12 months versus +12 months]

    Information concerning the laboratory and imaging assessments performed is available, but not their results. Special attention will be given to lung function, adrenal function, glycemia, and bone density assessments. The cumulative numbers of different assessments will be described and contrasted between the baseline and exposure periods.
