Eligibility
Key inclusion criteria
- 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.

Summary
Brief summary
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.
