An Open Label Access Study For Subjects Who Completed A1481156
A Local, Multicentre, Open Label Access Study, To Provide Sildenafil Therapy For Subjects Who Completed A1481156 Study And Are Judged By The Investigator To Derive Clinical Benefit From Continued Treatment With Sildenafil For Subjects In India

The purpose of this study is to provide sildenafil therapy to subjects who have completed the A1481156 study for the treatment of Pulmonary Arterial Hypertension (PAH) in India and are judged by the Investigator to derive clinical benefit from continued treatment with sildenafil citrate. Sildenafil citrate will be supplied for the treatment of Pulmonary Arterial Hypertension (PAH) until the subject continues to derive benefits from the treatment. The treating physicians (and the sponsor) will be responsible for reporting serious adverse events.

If a subject was receiving a higher dose in study A1481156 and the investigator believes that the subject requires continued treatment on that dose, or if dose reduction is judged to be associated with pulmonary arterial hypertension (PAH) deterioration in a particular subject, the higher dose may be made available, as judged on an individual basis on discussion with the sponsor.
