Chronic pulmonary hypertension (CPH) encompasses a heterogeneous group of disorders with the common feature of elevated pulmonary vascular resistance, accounting for approximately 42 million cases in 7MM in 2021. As per DelveInsight’s analysis, the 7MM prevalence is expected to increase at a considerable CAGR of 0.35% during the study period 2019–2032. The CPH prevalence is further divided into four main groups: Group 1, Group 2, Group 3, and Group 4. The most common group of CPH patients in Group 2 CPH (i.e., PH associated with left heart disease). It is estimated that approximately 3-4 million adults in the United States have Group 2 CPH. Furthermore, the World Health Organization (WHO) has organized pulmonary hypertension into five categories depending on the cause. Group 1 primary pulmonary hypertension, or pulmonary arterial hypertension (PAH). Among this group, idiopathic PAH is the most common condition, with other causes such as toxin-induced, connective tissue disorders and other related conditions being less prevalent. Group 2 involves pulmonary hypertension due to left heart disease, which is the most common cause of pulmonary hypertension. Group 3 pulmonary hypertension is due to lung diseases such as COPD and interstitial lung disease. Chronic pulmonary thromboembolism causes group 4 pulmonary hypertension, and group 5 pulmonary hypertension is due to unclear or multifactorial causes. 

Chronic pulmonary hypertension (CPH) is a catastrophic disease with high morbidity and mortality and no cure. Despite the rarity of the disease, the potential commercial opportunities for drugs approved for pulmonary hypertension are driven and important by the trend of premium pricing and polypharmacy. Although this chronic pulmonary hypertension market is crowded, commercial interest remains high. More potent and disease-modifying agents fuel this attention, along with the unserviced population lacking approved treatments. 

Epoprostenol (Flolan, Veletri) and treprostinil (Tyvaso, Remodulin, Orenitram) can be inhaled, injected, or taken by mouth. The drugs iloprost (Ventavis), bosentan (Tracleer), macitentan (Opsumit), ambrisentan (Letairis), Sildenafil (Revatio, Viagra), and tadalafil (Adcirca, Cialis, Alyq), amlodipine (Norvasc), diltiazem (Cardizem, Tiazac, others), nifedipine (Procardia), Warfarin (Jantoven), Digoxin (Lanoxin), Diuretics, Oxygen therapy, and various other therapies are being used widely to treat the disease.

Prominent Pharma Giants in the Chronic Pulmonary Hypertension Market

Attgeno AB’s Supernitro (Phase-II) is the first and only intravenous drug to treat acute high blood pressure in the lungs selectively. Supernitro working on Attgeno technology is based on ground-breaking research on nitric oxide and circulatory physiology. The method releases nitric oxide to specific organs in the body. It generates a range of new drug substances with unique properties that can be used in life-threatening medical conditions. Supernitro represents a great new step in the medical use of nitric oxide. The drug is developed to widen the blood vessels in the lungs selectively.

Cereno Scientific AB’s drug candidate CS1 (Phase-II) is a new advanced reformulation of valproic acid (VPA) and acts as an epigenetic modulator with anti-thrombotic, anti-inflammatory, anti-fibrotic, and pressure-relieving properties. CS1 is being developed as pulmonary arterial hypertension (PAH) treatment to offer patients a better, disease-modifying drug. CS1’s epigenetic mechanism is expressed through HDAC (histone deacetylase) inhibition. It brings a novel treatment approach to cardiovascular disease.

Liquidia Technologies’s Yutrepia (LIQ861) is an inhaled dry powder formulation of treprostinil designed using Liquidia’s PRINT technology to enhance deep-lung delivery using a convenient, palm-sized, disposable dry powder inhaler (“DPI”) for the treatment of PAH is currently registered. Liquidia believes LIQ861 can overcome the limitations of current inhaled therapies and has the potential to maximize the therapeutic benefits of treprostinil in treating PAH by safely delivering higher doses into the lungs.

The Changing Paradigm of the Chronic Pulmonary Hypertension Market 

Pulmonary Hypertension is a constantly evolving domain in which clinicians encounter a plethora of diagnostic and treatment issues. There is significant variety in Pulmonary Hypertension, which seldom manifests as an independent entity and is more frequently coupled with one or more predisposing factors, exposures, or disease states. The rates of clinical disease development and results vary greatly amongst people, and there is no generally successful Chronic Pulmonary Hypertension treatment method, even within a particular form of Pulmonary Hypertension. Because of these difficulties, continuous efforts to develop and standardize disease diagnosis, categorization, and management techniques are critical. These factors are expected to enhance the Chronic Pulmonary Hypertension market growth worldwide.

Moreover, promising pipelines and successful drug approvals have given the Chronic Pulmonary Hypertension market a considerable boost in recent years. The extensive research and development activities of massive pharma key players and the launch of various multiple-stage pipeline therapies are expected to dominate in the near future. The number of clinical trials for  Chronic Pulmonary hypertension (CPH) is also increasing; therefore, their success rate is also boosting the chances of commercial approval during the forecast period 2019–2032. This is also a major factor in the growth and development of the Chronic Pulmonary Hypertension market. Furthermore,  the government is also taking active steps that promote the growth of the Chronic Pulmonary Hypertension market. In addition, the increasing prevalence and awareness of the disease also drive the Chronic Pulmonary Hypertension market. Hence due to the aforementioned factors, the treatment market is expected to grow in the upcoming years.

FAQ

What is Chronic Pulmonary Hypertension?

Pulmonary hypertension encompasses a heterogeneous group of disorders with the common feature of elevated pulmonary vascular resistance. Pulmonary hypertension is a progressive disease with treatment focused on managing symptoms and treating underlying diseases.

What are the underlying causes of Chronic Pulmonary Hypertension? 

Some common underlying causes of pulmonary hypertension include high blood pressure in the lungs’ arteries due to some types of congenital heart disease, connective tissue disease, coronary artery disease, high blood pressure, liver disease (cirrhosis), blood clots to the lungs, and chronic lung diseases like emphysema. Genetics also plays a role.

What are the symptoms of Chronic Pulmonary Hypertension? 

The symptoms of pulmonary hypertension during the initial stage of the disease are common to many other medical conditions (e.g., difficulty breathing and fatigue). This often results in a delayed diagnosis until more severe symptoms arise, such as dizziness, chest pain, ankle swelling, or feeling the heart race or pound (palpitations). 

How is Chronic Pulmonary Hypertension diagnosed?

Diagnosis of pulmonary hypertension is commonly delayed as the presenting symptoms overlap with other disease processes. Other conditions to be considered in the differential diagnosis include, but are not limited to, congestive heart failure, coronary artery disease, pulmonary fibrosis, chronic obstructive pulmonary disease, valvular heart disease, hypothyroidism, and pulmonary embolism.
