研究概览
简要总结
AZD8848 is a new drug that is being tested for the treatment of asthma and allergic rhinitis (hayfever). This study will be in two parts and will include 59 asthmatic patients in total. The first part will investigate the tolerability and safety of AZD8848 while the second part will investigate both the therapeutic effect of AZD8848 and how well patients tolerate the drug.

结局指标
主要结局
FEV1, Late Asthmatic Response (LAR) - 1 Week After Last Dose
时间窗: 1 week after last dose
FEV1, Late Asthmatic Response (LAR), is derived as the ratio of FEV1 AUC 4-10h (computed using the trapezoidal formula divided by time) and the pre-challenge FEV1 measurement.
FEV1, Late Asthmatic Response (LAR) - 4 Weeks After Last Dose
时间窗: 4 weeks after last dose
FEV1, Late Asthmatic Response (LAR), is derived as the ratio of FEV1 AUC 4-10h (computed using the trapezoidal formula divided by time) and the pre-challenge FEV1 measurement.
FEV1, Late Asthmatic Response (LAR) - Pre-treatment
时间窗: Pre-treatment (Baseline measurement)
Forced Expiratory Volume in 1 second (FEV1), Late Asthmatic Response (LAR), is derived as the ratio of FEV1 Area Under Curve 4-10 hour post allergen challenge (AUC 4-10h) (computed using the trapezoidal formula divided by time) and the pre-challenge FEV1 measurement.
