April 28, 2017 updated by: PD Dr. Stephanie Korn, Johannes Gutenberg University Mainz

EVITA Trial: Effect of VItamin D as add-on Therapy for Vitamin D Insufficient Patients With Severe Asthma: a Randomized, Double-blind, Placebo-controlled Trial

The purpose of the EVITA trial is to compare the effects of vitamin D therapy with placebo on reducing the dose of inhaled or oral corticosteroids in patients with severe asthma and vitamin D insufficiency.

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

Patients with severe asthma represent the greatest unmet medical need among the asthmatic population, in particular due to their high risk of severe exacerbations. A substantial proportion of these patients does not achieve asthma control despite even high-dose ICS and LABA treatment, necessitating add-on therapy. For these patients oral corticosteroids (OCS) are a preferred treatment modality, which will inevitably lead to severe side effects. A high Proportion of patients with severe Asthma are Vitamin D insufficient (< 30 ng/ml). It is therefore tempting to speculate that vitamin D substitution in vitamin D insufficient patients who continue to experience suboptimal asthma control on ICS and LABA or ICS/LABA plus OCS treatment may boost corticosteroid responsiveness, thereby potentially reducing corticosteroid dose requirements and improving key parameters of asthma control.

The present study is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of treatment with vitamin D at a dose of 4000 IU/day administered daily following a single loading dose of 100 000 IU upon study entry over a period of 24 weeks in patients with severe asthma and vitamin D insufficiency. During the study, all patients will remain on their existing maintenance asthma therapy throughout the study, in addition to the study treatment, while reducing inhaled or oral steroids according to study protocol. The study consists of a 2-week run-in period, a 24 week double-blind treatment period including a 12 week steroid stable phase and two steroid reduction phases, followed by a follow-up visit 4 weeks after last study medication intake. The active treatment arm in this study will be standard of care plus vitamin D (loading dose of 100 000 IU upon study entry, to be followed by 4000 IU/day for the rest of the study period) while the comparator arm will be standard of care plus placebo.

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.
