  Purpose

This randomised, double-blind, placebo-controlled study will evaluate the efficacy and safety of ADC3680 administered once daily as an add-on therapy to inhaled corticosteroids and when co-administered with montelukast in patients with inadequately-controlled asthma. Patients will be randomised to 3 Arms to receive ADC3680, placebo or montelukast.

Arms Assigned Interventions
Experimental: ADC3680
ADC3680 oral once daily
Drug: ADC3680
ADC3680 for 12 weeks plus montelukast for the last 2 weeks of the dosing period
Placebo Comparator: Placebo
Placebo oral once daily
Drug: Placebo
Placebo for 12 weeks plus montelukast for the last 2 weeks of the dosing period
Active Comparator: montelukast
montelukast oral once daily
Drug: montelukast
montelukast for 12 weeks

Detailed Description:

This is a multi-centre, randomised, placebo-controlled, double blind, parallel group 3-arm study (including montelukast as an active comparator) designed to compare the efficacy and safety of a once daily dose of ADC3680 with placebo in subjects with inadequately-controlled asthma despite receiving a low to moderate dose of an ICS controller therapy, over a 10 week treatment period. At the end of the 10 week treatment period open label montelukast (10 mg) will be added to ADC3680 and placebo arms for a two week extension period to assess whether efficacy of ADC3680 is enhanced by the addition of montelukast compared with montelukast alone. The montelukast arm will continue with 10 mg montelukast alone.
