The Special Drug Use-results Survey (All-Case Surveillance) of Ofev® Capsules in Patients With Idiopathic Pulmonary Fibrosis (IPF) in Japan

This is a non-interventional study based on new data collection to gather real-world information (i.e., data under routine medical practice) on safety and effectiveness of the Ofev® Capsules treatment.

The study will consist of a baseline visit and follow-up visits at Week 4, 13, 26, 39, 52, 65, 78, 91 and 104 for patients who have newly initiated Ofev® Capsules. The patients will be followed up until discontinuation of Ofev® Capsules treatment.

As this is an observational study, no specific treatment is mandated or withheld from the patients. The choice of maintenance treatment for IPF must be according to regular medical practice and at the discretion of the physician (i.e., no randomised assignment of patient to treatment is performed).

All patients administrated Ofev® Capsules after the launch at the sites contracted with the sponsor will be registered. The Case Report Forms (CRFs) of 1000 patients will be collected. However the patient registration continues until the approval condition has been removed.

Patients participating in the subsequent follow-up will undergo regular observations. These observations should be reported after approximately Week 4, 13, 26, 39, 52, 65, 78, 91 and 104 since the initiation of Ofev® Capsules as long as they continue to receive the treatment. Patients will not be followed any longer once they are reported to have discontinued the Ofev® Capsules treatment.
