Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
This is an intention to treat pilot study (single-centre, open label, uncontrolled) to evaluate the effects of sildenafil (REVATIO™ ) on oxygen saturation in patients with pulmonary arterial hypertension related to Eisenmenger physiology. We aim to include 12 patients at a single site. End of trial will be the last visit of the last subject undergoing the trial. |
