Nation-wide Health Resource Consumption and Costs Associated With Mepolizumab (Resala)

October 18, 2023 updated by: University Hospital, Montpellier

Nation-wide Health Resource Consumption and Costs Associated With Mepolizumab (Nucala): a French SNDS Database Study

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

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

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").

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.

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
The change in total health care costs for the year preceding the initiation of mepolizumab versus for the year after.
Time Frame: -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
