Familial Primary Pulmonary Hypertension (FPPH) Overview
FPAH, also known as heritable pulmonary arterial hypertension (HPAH), is a form of PAH that arises due to genetic mutations or occurs within families. It belongs to WHO Group 1 pulmonary hypertension, which is characterized by the narrowing of small blood vessels in the lungs. This group also includes idiopathic PAH, where the underlying cause of the vascular narrowing remains unknown. Within WHO Group 1, several subtypes exist, including heritable or familial pulmonary hypertension is often linked to mutations in specific genes, such as the BMPR2 gene. Individuals affected by this condition often experience early symptoms such as shortness of breath (dyspnea), fatigue, fainting spells (syncope), chest discomfort, palpitations, and swelling in the lower limbs (pedal edema). On physical examination, notable precordial signs may include a loud and palpable second heart sound, right ventricular heave, pulmonary ejection click, and murmurs associated with pulmonary and tricuspid valve regurgitation. These clinical features reflect the strain placed on the right side of the heart due to elevated pressure in the pulmonary arteries.
Familial Primary Pulmonary Hypertension (FPPH) Diagnosis and Treatment Overview
FPPH is diagnosed through a combination of clinical evaluation, imaging, and genetic testing. An echocardiogram, a noninvasive ultrasound of the heart is commonly used to screen for PAH, although it may be costly and not always accurate. Right heart catheterization provides a direct measurement of pulmonary artery pressure and is considered the gold standard. Blood tests help rule out other conditions and assess overall health. Genetic testing, particularly for BMPR2 mutations found in about 80% of affected families, can identify at-risk relatives but does not detect current symptoms. If the specific mutation in a family is unknown, DNA from an affected member may be needed. Treatment includes medications that relax pulmonary blood vessels and reduce pressure, supplemental oxygen for low oxygen levels, and lifestyle changes such as regular exercise and a balanced diet. These strategies aim to manage symptoms, slow disease progression, and improve quality of life.

Marketed Drugs
WINREVAIR (sotatercept-csrk): Merck
WINREVAIR (SOTATERCEPT-CSRK) is a first-in-class fusion protein therapy that targets the transforming growth factor-beta (TGF-β) superfamily pathway, which plays a central role in vascular remodeling in PAH. By acting as a ligand trap for activing and Growth Differentiation Factors (GDFs), WINREVAIR restores the balance between pro-proliferative and anti-proliferative signaling in pulmonary vascular cells. This rebalancing reduces abnormal vascular remodeling, improves pulmonary vascular resistance, and enhances right heart function. Through its novel mechanism, WINREVAIR offers a disease-modifying approach that goes beyond symptomatic relief, providing meaningful improvements in exercise capacity, functional class, and long-term outcomes for patients with PAH, including familial forms.
OPSUMIT (macitentan) is an orally active dual endothelin receptor antagonist developed by Johnson & Johnson for the treatment of PAH. It selectively blocks endothelin receptors ETA and ETB, thereby counteracting the effects of endothelin-1, a potent vasoconstrictor and promoter of vascular smooth muscle proliferation. By inhibiting this pathway, OPSUMIT reduces vasoconstriction, limits vascular remodeling, and improves pulmonary hemodynamics. Unlike earlier endothelin receptor antagonists, macitentan was designed with enhanced tissue penetration and sustained receptor binding, leading to improved efficacy and tolerability. Clinical studies have demonstrated that OPSUMIT delays disease progression, lowers the risk of hospitalization, and enhances long-term outcomes, making it a cornerstone oral therapy for PAH, including familial forms.
ORENITRAM (TREPROSTINIL) is an oral prostacyclin analogue therapy that targets the prostacyclin (IP) receptor pathway, which is critical in regulating vascular tone and inhibiting smooth muscle proliferation in PAH. By directly stimulating the IP receptor, ORENITRAM promotes vasodilation of pulmonary and systemic arteries, reduces pulmonary vascular resistance, and inhibits platelet aggregation and vascular remodeling. This dual action helps improve blood flow, alleviate symptoms, and slow disease progression. Through its oral formulation, ORENITRAM provides a convenient alternative to parenteral prostacyclin therapies, supporting long-term disease management. By improving exercise capacity, functional outcomes, and overall quality of life, ORENITRAM plays an essential role in the treatment of patients with PAH, including those with familial forms.
