Indications & Usage
1 INDICATIONS AND USAGE Adempas is a soluble guanylate cyclase (sGC) stimulator indicated for the treatment of adults with: • Persistent/recurrent Chronic Thromboembolic Pulmonary Hypertension (CTEPH) (WHO Group 4) after surgical treatment or inoperable CTEPH to improve exercise capacity and WHO functional class.
( 1.1 ) • Pulmonary Arterial Hypertension (PAH) (WHO Group 1) to improve exercise capacity, improve WHO functional class and to delay clinical worsening.
( 1.2 ) 1.1 Chronic-Thromboembolic Pulmonary Hypertension Adempas is indicated for the treatment of adults with persistent/recurrent chronic thromboembolic pulmonary hypertension (CTEPH), (WHO Group 4) after surgical treatment, or inoperable CTEPH, to improve exercise capacity and WHO functional class [see Clinical Studies ( 14.1 )].
1.2 Pulmonary Arterial Hypertension Adempas is indicated for the treatment of adults with pulmonary arterial hypertension (PAH), (WHO Group 1), to improve exercise capacity, WHO functional class and to delay clinical worsening.
Efficacy was shown in patients on Adempas monotherapy or in combination with endothelin receptor antagonists or prostanoids.
Studies establishing effectiveness included predominately patients with WHO functional class II–III and etiologies of idiopathic or heritable PAH (61%) or PAH associated with connective tissue diseases (25%) [see Clinical Studies ( 14.2 )] .

Adverse Reactions
6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: • Embryo-Fetal Toxicity [see Warnings and Precautions ( 5.1 )] • Hypotension [see Warnings and Precautions ( 5.3 )] • Bleeding [see Warnings and Precautions ( 5.4 )] Adverse reactions occurring more frequently (≥3%) on Adempas compared to placebo are headache, dyspepsia/gastritis, dizziness, nausea, diarrhea, hypotension, vomiting, anemia, gastroesophageal reflux, and constipation.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety data described below reflect exposure to Adempas in two, randomized, double blind, placebo-controlled trials in patients with inoperable or recurrent/persistent CTEPH (CHEST-1) and treatment naive or pre-treated PAH patients (PATENT-1).
The population (Adempas: n = 490; Placebo: n = 214) was between the age of 18 and 80 years [see Clinical Studies ( 14.1 , 14.2 )].
The safety profile of Adempas in patients with inoperable or recurrent/persistent CTEPH (CHEST-1) and treatment naive or pre-treated PAH (PATENT-1) were similar.
Therefore, adverse drug reactions (ADRs) identified from the 12 and 16 week placebo-controlled trials for PAH and CTEPH respectively were pooled, and those occurring more frequently on Adempas than placebo (≥3%) are displayed in Table 1 below.
Most adverse reactions in Table 1 can be ascribed to the vasodilatory mechanism of action of Adempas.
The overall rates of discontinuation due to an adverse event in the pivotal placebo-controlled trials were 2.9% for Adempas and 5.1% for placebo (pooled data).

With longer observation in uncontrolled long-term extension studies the safety profile was similar to that observed in the placebo controlled phase 3 trials.
