Who may be able to join

  • Participants must have a duration of asthma of greater than one year.
  • They must have confirmed asthma defined as: (i) forced expiratory volume (FEV1) reversibility greater than or equal to 12%, and greater than or equal to 200 mL at baseline within 30 minutes after administration of salbutamol (200 to 400 micrograms), or (ii) airway hyperresponsiveness defined as a greater than 20% decline in FEV1 during a direct bronchial provocation test or greater than 15% decline during an indirect bronchial provocation test, or (iii) peak expiratory flow (PEF) variability of greater than 15% between the two highest and two lowest peak expiratory flow rates during 14 days.
  • They must have evidence of poor asthma control despite optimal ICS and long acting beta agonist (LABA), be treated by a respiratory physician or immunologist, and have demonstrated acceptable adherence and inhaler technique. Poor control is defined as: evidence of an FEV1 <80% of predicted in the last year on at least one occasion; treatment with OCS, either daily for at least 6 weeks, or a cumulative dose of OCS of at least 500 mg prednisolone equivalent in the previous 12 months, unless contraindicated or not tolerated.
  • In addition they must demonstrate an: (a) an Asthma Control Questionnaire (ACQ-5)38 score of at least 2.0, as assessed in the previous month, and (b) while receiving optimised asthma therapy in the past 12 months, experienced at least 1 admission to hospital for a severe asthma exacerbation, or 1 severe asthma exacerbation, requiring documented use of OCS initiated or increased for at least 3 days, or parenteral corticosteroids prescribed/supervised by a physician.
  • They must also demonstrate evidence of a dual allergic/ eosinophilic phenotype. This is defined as: a total serum IgE >30IU/mL, past or current evidence of atopy documented by skin prick testing or radioallergosorbent assay, and the participant must have a blood eosinophil count greater than or equal to 300 cells per microlitre in the last 6 weeks.

About this study

Official title: How to "Choosebetweenamab" for Severe Asthma, Comparing Treatment With Mepolizumab and Omalizumab for Patients With Severe Allergic and Eosinophilic Asthma.

Mepolizumab is an anti-interleukin-5 ( IL-5) monoclonal antibody that neutralizes IL-5 and reduces eosinophil counts in both sputum and blood. Omalizumab is an anti-immunoglobulin E (IgE) monoclonal antibody (mAb) used in the treatment of severe allergic eosinophilic asthma

The investigators propose that in patients with the dual phenotypes of severe allergic and eosinophilic asthma, that Mepolizumab is as effective as Omalizumab. However, this trial will also identify key clinical biomarkers that will clarify which patients will respond best to each of these interventions.

This study will be the first direct clinical comparison of these agents and will apply expert clinical characterization, along with cutting edge biotechnology to better inform treatment choices for severe asthma. This is an important and urgent management problem facing the Australian pharmaceutical scheme, where imprecision in prescribing will result in reduced clinical effectiveness as well as substantial and sustained costs.

Read the detailed description

'Choosebetweenamab' will compare active treatment arms (Mepolizumab and Omalizumab) for efficacy and adverse events in a Phase 4, parallel arm, randomized controlled trail setting with computer generated randomization (permuted block randomization, with block sizes of 4 or 6, stratified by baseline eosinophil count using a median split). There is no placebo control. Particpants will not be blinded but masking will be used for people assessing outcomes and analyzing data.

'Chossebetweenamab' will also include a secondary outcome substudy (ISS 11066) to assess biomarkers of efficacy response to treatment using single cell sequencing of peripheral blood cells. Blood samples are taken from the randomized patients in each treatment arm (Mepolizumab and Omalizumab) at baseline and gene expression changes assessed using transcriptomic single cell sequencing of patient white blood cells. The data generated from this will be compared to the clinical outcomes of 'Choosebetweenamab' at all follow-up time points. Single cell gene expression and cell type cluster patterning will be compared to the primary and secondary outcomes to identify baseline predictors (gene and cell type) of treatment efficacy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. ACQ5

    The primary outcome will be Asthma control questionairre (ACQ)5, adjusted for baseline ACQ5

    Measured: Assessed after 6 months treatment

Secondary outcomes (10)
  1. Exacerbations

    Number of Exacerbations, requiring change in oral corticosteroids, with either a course of prednisone for at least 3 days, or in those on regular OCS an increase in dose of at least 50% for at least 3 days. Patient reported monthly

    Measured: every month up to 6 months after treatment commenced

  2. Time to first exacerbation reported, by patient or health provider

    Time to first exacerbation reported, by patient or health provider
