Wyeth Zambon Background Idiopathic pulmonary fibrosis (IPF): a progressive and fatal lung disease Median survival: 2-5 years Clinical course: insidious decline in pulmonary function, increasingly limiting routine physical activity Progressive deterioration is inevitable - with considerable inter- and intra-patient variability Change in forced vital capacity (FVC): consistently shown to be a strong predictor of mortality Agents that attenuate the decline in FVC may play an important role in the management of patients with IPF Epithelium / fibroblast interaction in lung fibrosis Intrinsic: mutations (SP-A, -D, telomerase, MUC5B) -> ER stress Injury Epithelial cells EMT
