A Study to Observe the Safety, Tolerability, and Efficacy of Remodulin

A Multi-center, Prospective Study to Observe the Safety, Tolerability, and Efficacy of Remodulin® in Patients With Pulmonary Arterial Hypertension

This is a multi-center, single-arm, prospective study to enroll patients diagnosed as pulmonary arterial hypertension. The objective in this study is to observe the efficacy and safety of treprostinil in subjects with pulmonary arterial hypertension.

This is a multi-center, single-arm, prospective study to enroll patients diagnosed as pulmonary arterial hypertension. The expected study period will be 2 years. PAH patients, who met NHI criteria, to receive treprostinil subcutaneously/ intravenously, will be invited to join this study for observation. The dosage and administration schedule of study medication will be judged by investigators. If the eligibility criteria have been met and the subject have signed the informed consent, the subjects will be enrolled into this study. There will be 10 visits: Visit 1 (Screening visit, Week -2 ~ -1), Visit 2 (Week 1, initial of use treprostinil), Visit 3 to 9 (Week 13 to 85), Visit 10 (Week 97). The Day 1 in Week 1 should be the start day of treprostinil treatment. Subjects will be returned to the clinics every 3 months (i.e. 12 weeks) after Visit 2. The NT-proBNP level, WHO functional class, 6-minute walk distance, echocardiography, pulse oximetry, modified Borg Dyspnea Scale, SF-36 questionnaire, and dosage regimens of treprostinil (including dose adjustment) will be collected. For time to clinical worsening and death, it will be followed up during study period. All intercurrent events within 24 months will be recorded. Safety information, including vital signs, and physical exams will be checked. Adverse events of special interest (AESIs) will be reviewed every visit by using a predesignated AESI checklist.

Inclusion Criteria:

• Diagnosed with symptomatic idiopathic or heritable PAH classified as WHO functional class III and IV symptoms.
• PAH patient, who met NHI criteria, will be scheduled to receive subcutaneous/intravenous treprostinil treatment.
• Ability to adhere to the study visit schedule and understand and comply with all protocol requirements.
• Will provide completed and signed written informed consents

Exclusion Criteria:

• Active treatment with injectable prostanoids different from subcutaneous/intravenous treprostinil
