Outcomes

Primary Outcome Measures

Efficacy on asthma symptoms
Asthma Control Test: 5 items of score 1 to 5 about symptoms, with result of 20 or above indicates good control; 15 to 19 indicates no good control and below 15 indicates no control at all, and a change of 3 points considered as clinically significant.
Efficacy on lung function
Lung function measured as forced expiratory volume in one sec (FEV1), % predicted value (normal value of 80% predicted or above, and change of 100 mL considered as clinically significant).
Efficacy on severe exacerbations
Number of exacerbation(s) per period of time (corrected per year) requiring systemic corticosteroid treatment for at least 3 days, and/or emergency visit or hospitalization for acute asthma.

Secondary Outcome Measures

Predictive factors of therapeutic response
The putative predictive factors of therapeutic response to omalizumab or mepolizumab which will be assayed are the following: age at onset, year (> or < 30yrs); presence of nasal polyps, Y/N; blood eosinophils, n/microliter (< or > 300/microl); serum total IgE, units/L; serum periostin, ng/ml. A proteomic analysis will also be carried out on plasma samples.

5. Study Description

Brief Summary
Pragmatic trial to define the magnitude and the predictive factors of the response to omalizumab and mepolizumab in adult patients with severe refractory asthma and eligible to both therapies.
Detailed Description
Title "PREDICTUMAB: Predictive factors and magnitude of response to omalizumab and mepolizumab in allergic and eosinophilic severe asthma: a multicenter, open, active-controlled, randomized trial in adult patients in Belgium". Rationale and background New treatments are now available to treat severe refractory asthma, which affects about 3 to 5% of asthma patients. In particular, biological therapies using monoclonal antibodies targeted to immunoglobulin E (IgE) or interleukin (IL)-5 (and in the future other cytokines or growth factors) benefit to certain patients. Identifying those patients who will better benefit from a specific treatment requires the validation of features (clinical traits, biomarkers) that are predictive of the therapeutic outcome. Such predictive strategy is not available to decide whether anti-IgE (omalizumab) or anti-IL-5 (mepolizumab) should be prioritized in patients who are eligible to both therapies. In addition, the comparison of the magnitude of the clinical benefits achieved by these therapies remains unexplored in this population. Study Design The study is designed to initially randomly allocate patients from two strata (with or without maintenance oral corticosteroids) to oma- vs mepolizumab. According to the evaluation of response (at 4 or 6 months, respectively), subjects will then be either prolonged (for 12 months, for both therapies) on the same therapy, or switched to the other. For those who were switched, treatment will be prolonged (or not, in dual failers) after 4 or 6 months according to their evaluation of response. Time-points for analysis will be at 4 or 6 months, 10 months (interim analysis) and 18 or 22 months (final, posttreatment analysis). State-of-the-art Asthma is one of the most frequent chronic diseases, affecting 5 to 10% of the population worldwide. Omalizumab and mepolizumab represent the approved antibodies that are indicated in allergic and eosinophilic phenotypes of severe asthma respectively. However, if some patients fall into only one phenotypic category based on these criteria, a substantial number of patients are potentially eligible to both therapies. In those patients, no information is available to orientate towards a preferable therapy as the predictive weight of additional phenotypic traits, such as associated nasal polyps or early- versus late onset of disease, remains unknown. In addition, no head-to-head comparison of these therapies is available in this population. Objectives of the study Primary objectives To determine clinical features and blood (or sputum) biomarkers able to predict a better response to omalizumab or mepolizumab in severe asthma patients eligible to both therapies. To determine the magnitude of response, in terms of improvement in symptoms, exacerbation rate and/or lung function, in responders to omalizumab vs mepolizumab. Secondary objectives To compare the global baseline characteristics (clinical and biological features) of patients responding to omalizumab vs mepolizumab. Management and reporting of adverse events. If during the study, an adverse event (AE) (serious or non-serious) is identified as attributed to omalizumab or mepolizumab, this will be documented as appropriate in routine good clinical practice, to the Federal Agency of Medicines and Products of Health (AFMPS) as well as to the Central Ethic Committee. Confidentiality of data. The identity and participation of subjects will remain strictly confidential, according to Belgian laws dated 8 Dec 1992 related to the protection of private life and dated 22 Aug 2002 related to patient rights. Specimens and associated data will be labeled with unique patient identification number. Data will be anonymized in all files, results and publications related to the study. The promoter confirms to authorize the regulatory surveillance, examination and controls by competent authorities, by allowing direct access to database/files, and this in full respect of confidentiality.

Factorial Assignment
Model Description
Severe asthma patients who are eligible to both anti-IgE (omalizumab) and anti-IL-5 (mepolizumab) therapies, will be randomized to decide the first treatment to start. Patients will then be prolonged or switched to the other according to the clinical response. There will be 5 possibilities: oma(lizumab) group, mepo(lizumab) group, oma-mepo switch, mepo-oma switch, and oma/mepo failure.
Masking
Outcomes Assessor
Masking Description
The analysis of the response rate and magnitude, as well as of biomakers predicting the response, will be performed by an independent assessor and a biostatistician.

Intervention Name(s)
Randomisation to omalizumab
Other Intervention Name(s)
Active-controlled
Intervention Description
The only intervention will be that allocation of patients to omalizumab or mepolizumab (to both of which patients will be eligible) will be randomized, to avoid that the initial decision is biased by confounding factors that are likely, but unproven, to affect the treatment response. Then, in case of non-response, patients will be switched to the other drug, as routine clinical practice would indicate.
