Abstract

Background BI 671800 is an antagonist of the PGD2 receptor, CRTH2. PGD2 stimulates bronchoconstriction and allergic airway inflammation in animal models. Inhibition of CRTH2 may reduce airway inflammatory cells, IL -4, -5, -13 production, serum IgE and airway hyper reactivity.
Objective To investigate the efficacy and safety of BI 671800 administered once in the morning or evening versus a split twice daily dose compared to placebo in poorly controlled asthma patients as add on therapy to fluticasone propionate (FP) MDI (88 μg, bid).
Methods Adults with asthma (FEV1 60-85% and ACQ >= 1.5) were enrolled in a randomized, double-blind, three period, incomplete cross-over study comparing BI 671800 400 mg AM, PM or 200 mg bid with matching placebo over 3 consecutive 4-week treatment periods. The primary study outcome was change in trough FEV1.
Results 108 patients were randomised (mean age 41 yrs, FEV1 73%, ACQ 2.13). Change from baseline in mean (SE) trough morning FEV1 % predicted versus placebo were 0.08% (0.62), 0.67% (0.62) and 0.28% (0.61) and change in ACQ mean (SE) scores were -0.056 (0.063), -0.026 (0.063) and -0.093 (0.062) versus placebo for 200 bid, 400 PM, and 400 AM BI 671800 respectively (all values one-sided p > 0.025). No imbalance in adverse events, or differences in vital signs or laboratory assessments were observed.
Conclusion Total daily treatment with 400 mg BI 671800 did not demonstrate additional effect on FEV1 on top of FP. BI 671800 was well tolerated at total daily doses of 400 mg for 4 weeks.
