Oral Ralinepag
Ralinepag immediate-release (IR) capsules of 10, 20, 30, 40, and 100 mcg or extended-release (XR) tablets of 50, 250, and 400 mcg for oral administration were provided. The starting dose and titration schedule were determined for each subject in accordance with the starting dose and titration schedule optimized from Study APD811-003. Subjects in the placebo treatment group in Study APD811-003 underwent a dose titration period (up to 9 weeks) with ralinepag until a stable maximum tolerated dose (MTD) was reached. Ralinepag: Active

WHO/NYHA FC was measured at Baseline (prior to starting study drug) and every 3 months thereafter including at the End of Study and 28-Day Follow-up Visits. FC recorded as I, II, III, or IV based on the following: I: PH but without limitation of physical activity; physical activity without undue dyspnea or fatigue, chest pain or near syncope. II: PH with slight limitation of physical activity; physical activity causes undue dyspnea or fatigue, chest pain or near syncope. III: PH with marked limitation of physical activity; less than ordinary activity causes undue dyspnea or fatigue, chest pain or near syncope. IV: PH with inability to carry out any physical activity without symptoms. Signs of right heart failure. Dyspnea and/or fatigue at rest. Discomfort is increased by any physical activity.

Ralinepag IR capsules of 10, 20, 30, 40, and 100 mcg or XR tablets of 50, 250, and 400 mcg for oral administration were provided. The starting dose and titration schedule were determined for each subject in accordance with the starting dose and titration schedule optimized from Study APD811-003. Subjects in the placebo treatment group in Study APD811-003 underwent a dose titration period (up to 9 weeks) with ralinepag until a stable MTD was reached. Ralinepag: Active There was only 1 active dose group in this open-label study (oral ralinepag). Subjects included in this study received ralinepag and completed previous Study APD811-003, or received placebo and discontinued Study APD811-003 due to clinical worsening. All subjects enrolled in Study APD811-007 received open-label treatment with oral ralinepag IR or XR formulations. The starting dose and titration schedule were individually determined in accordance with the starting dose and titration schedule optimized during Study APD811 003. Adjustments in the dose and titration schedule were made according to subject tolerability.

n=45 participants at risk
Ralinepag IR capsules of 10, 20, 30, 40, and 100 mcg or XR tablets of 50, 250, and 400 mcg for oral administration were provided. The starting dose and titration schedule were determined for each subject in accordance with the starting dose and titration schedule optimized from Study APD811-003. Subjects in the placebo treatment group in Study APD811-003 underwent a dose titration period (up to 9 weeks) with ralinepag until a stable MTD was reached. Ralinepag: Active There was only 1 active dose group in this open-label study (oral ralinepag). Subjects included in this study received ralinepag and completed previous Study APD811-003, or received placebo and discontinued Study APD811-003 due to clinical worsening. All subjects enrolled in Study APD811-007 received open-label treatment with oral ralinepag IR or XR formulations. The starting dose and titration schedule were individually determined in accordance with the starting dose and titration schedule optimized during Study APD811 003. Adjustments in the dose and titration schedule were made according to subject tolerability.
