Brief summary

This is a double-blind, randomised, placebo-controlled, cross-over, Phase 2 trial evaluating two doses (a low and a high) of CRD007 for the treatment of asthmatic trial subjects with a positive asthma test (mannitol challenge) prior to enrolment.

Detailed description

The present trial will include subjects with diagnosed asthma in a provocation model which mimics assessments of asthma control. Mannitol challenge is an indirect asthma provocation test, which requires the presence of inflammatory cells, particularly mast cells, in the airways. The trial involved in total 5 subject visits and will last for a maximum of 30 days for each subject from Visit 2 (Randomisation) to Visit 5 (Follow up). Visit 2,3, and 4 will be treatment visits where Investigational Medicinal Product (IMP) is administrated 3 hours before the Mannitol challenge.

Design outcomes

Primary

MeasureTime frameDescription
PD15 for mannitol after treatment with CRD007 and placeboForced expiratory volume at one second (FEV1) manoeuvres are performed 60 seconds after each doseThe FEV1 value taken after the 0 mg capsule is taken as pre-challenge FEV1 and used to calculate the percentage decrease in FEV1 in response to the mannitol challenge. The test ends when the FEV1 has fallen by 15% or more (PD15)
