Approaching and Evaluating PAH
Comprehensive, proactive assessments can help shape treatment approaches to individualize the path to low-risk status for people with PAH.1
Clinical outcomes have improved as advancements in approved PAH treatment options evolve over time.2-6 However, studies from the last few decades indicate long-term prognosis for patients with PAH has room to improve.7
Learn more about how a detailed risk stratification can influence your PAH treatment plan.
Time Is Critical—Prioritize Early Results
According to a landmark analysis in the SERAPHIN trial, patients who experienced a morbidity event before the month 3 landmark had a >3x higher risk of mortality.8*
The SERAPHIN trial evaluated the efficacy and safety of the endothelin receptor antagonist macitentan. The purpose of this analysis was to assess the impact of morbidity events on the risk of subsequent mortality using the landmark method and data from the SERAPHIN study.8
*According to SERAPHIN, a morbidity event is defined as the infusion of IV or SC prostanoids, a lung transplantation, an atrial septostomy, or the clinical worsening of PAH. This is defined as the occurrence of all 3 of the following: a decrease in 6MWD of >15% from baseline, worsening of PAH (defined as either higher FC or worsening of signs of right heart failure that did not respond to oral diuretic therapy), and the need for additional treatment for PAH.8
Risk. Time. Act.
Some intermediate-risk patients may appear stable in measures like FC and 6MWD at 3- to 6-month follow-ups, even though right ventricular function is declining.9
Assessing right heart function and setting time-bound goals for treatment in 3- to 6-month intervals can help you identify unsatisfactory clinical response and act in a timely manner.1,10
6MWD=6-minute walk distance; FC=functional class; IV=intravenous; PAH=pulmonary arterial hypertension; SC=subcutaneous.
Important Safety Information
Warnings and Precautions
- Chronic intravenous (IV) infusions of Remodulin delivered using an external infusion pump with an indwelling central venous catheter are associated with the risk of blood stream infections (BSIs) and sepsis, which may be fatal. Therefore, continuous subcutaneous (SC) infusion is the preferred mode of administration.
- Avoid abrupt withdrawal or sudden large reductions in dosage of Remodulin, which may result in worsening of PAH symptoms.
- Titrate slowly in patients with hepatic or renal insufficiency, because such patients will likely be exposed to greater systemic concentrations relative to patients with normal hepatic or renal function.
- Remodulin is a pulmonary and systemic vasodilator. In patients with low systemic arterial pressure, treatment with Remodulin may produce symptomatic hypotension.
- Remodulin inhibits platelet aggregation and increases the risk of bleeding.
Adverse Reactions
- In clinical studies of SC Remodulin infusion, the most common adverse events reported were infusion site pain and infusion site reaction (redness, swelling, and rash). These symptoms were sometimes severe and sometimes required treatment with narcotics or discontinuation of Remodulin. The IV infusion of Remodulin with an external infusion pump has been associated with a risk of blood stream infections, arm swelling, paresthesias, hematoma, and pain. Other common adverse events (≥3% more than placebo) seen with either SC or IV Remodulin were headache (27% vs. 23%), diarrhea (25% vs. 16%), nausea (22% vs. 18%), rash (14% vs. 11%), jaw pain (13% vs. 5%), vasodilatation (11% vs. 5%), edema (9% vs. 3%), and hypotension (4% vs. 2%).
Drug Interactions
- Remodulin dosage adjustment may be necessary if inhibitors or inducers of CYP2C8 are added or withdrawn.
Specific Populations
- In patients with mild or moderate hepatic insufficiency, decrease the initial dose of Remodulin to 0.625 ng/kg/min of ideal body weight, and monitor closely. Remodulin has not been studied in patients with severe hepatic insufficiency.
- Safety and effectiveness of Remodulin in pediatric patients have not been established.
- It is unknown if geriatric patients respond differently than younger patients. Caution should be used when selecting a dose for geriatric patients.
- There are no adequate and well-controlled studies with Remodulin in pregnant women. It is not known whether treprostinil is excreted in human milk or if it affects the breastfed infant or milk production.
Indication
Remodulin is a prostacyclin vasodilator indicated for the treatment of pulmonary arterial hypertension (PAH; WHO Group 1) to diminish symptoms associated with exercise. Studies establishing effectiveness included patients with NYHA Functional Class II-IV symptoms and etiologies of idiopathic or heritable PAH (58%), PAH associated with congenital systemic-to-pulmonary shunts (23%), or PAH associated with connective tissue diseases (19%).
In patients with PAH requiring transition from epoprostenol, Remodulin is indicated to diminish the rate of clinical deterioration. Consider the risks and benefits of each drug prior to transition.
