Summary

This is a study to demonstrate the feasibility of an individual dose titration scheme based on the systolic blood pressure with a dose range from 1.0 mg TID to 2.5 mg TID. Patients suffering from chronic thromboembolic pulmonary hypertension (CTEPH) or pulmonary arterial hypertension (PAH) will be included. After diagnosis by an expert center, patients receive medication three times a day starting with 1.0 mg TID. The first tablets are given in the hospital, then the patients are allowed to go home and take the medication at home. After 2 weeks, patients return to the hospital for an ambulatory visit and the dose may be increased based on the actual condition of the patient (blood pressure and adverse events). Several measurements will be performed to test the efficacy of the drug and whether there are any unwanted reactions to the drug (blood tests, ECG, 6 minute walk test, imaging by Echo, quality of life scores). The dose of the drug will then be increased further until unwanted effects may occur or the blood pressure drops to low. The highest dose tested will be 2.5 mg TID. After 12 weeks the patient is going to stay in the hospital again and a right heart catheter is performed to examine the changes in hemodynamics after 12 weeks of treatment with the drug. If the patients give their consent they can enter a long-term extension trial continuing on BAY63-2521 with the dose reached after 12 weeks. Every 3 months an ambulatory visit at the specialist center will be performed including measurements of safety (blood tests, ECG, clinical assessment) and efficacy (6 minute walk test, Borg dyspnea scale, NT-pro BNP). Blood tests and ECG have been removed begin of 2013 as safety parameter by amendment 7; furthermore Borg dyspnea score and NT-proBNP have been removed as efficacy parameter.

Initially the inclusion of ten patients suffering from chronic thromboembolic pulmonary hypertension (CTEPH) or pulmonary arterial hypertension (PAH) was planned. Later on the patient number was amended and 75 patients entered the trial.

Furthermore the trial duration was extended and a long term treatment with BAY63-2521 was offered to the patients. Finally 68 patients moved over to the long term extension period of the trial.
