Global Pulmonary Arterial Hypertension Market and Forecast Analysis Report 2021-2027 – ResearchAndMarkets.com

DUBLIN–(BUSINESS WIRE)–The “Pulmonary Arterial Hypertension Market and Forecast Analysis to 2025” drug pipelines has been added to ResearchAndMarkets.com’s offering.

The report estimates that in 2018, there were approximately 218,500 prevalent cases of pulmonary arterial hypertension (PAH) in individuals of all ages worldwide, and forecasts that number to increase to 241,800 prevalent cases by 2027.

Actelion’s TRITON study, which investigated the use of a triple combination of Opsumit (ERA), Adcirca (PDE5i), and Uptravi (prostacyclin) in WHO FC II and III patients, failed to achieve the primary endpoint of an improvement in pulmonary vascular resistance. Notably, there was a numerical improvement of 41% in hospitalization and all-cause death; however, this was not statistically significant.

If additional larger trials reveal a significant clinical benefit in disease progression, this will allow prostacyclins to build upon the prevailing trend towards early implementation of polytherapy, which was first established through the AMBITION trial with the dual combination of an ERA and a PDE5i. Additionally, this will markedly expand the prostacyclin class’s potential by encouraging first-line uptake alongside Opsumit, which is a market leader.

Historically, ERAs have been the most commercially lucrative class; however, in 2019, prostacyclins succeeded them, with total sales of $2,675m versus $2,286m for ERAs. The publisher anticipates that the gap between prostacyclins and ERAs will widen further over the forecast period as ERAs are under rising threat from both generics and the increasing trend of prostacyclin use in triple combination therapies.

The PDE5i class, which traditionally held a significant portion of market share, has faced fierce generic competition, with both Adcirca and Revatio being subject to generic erosion since 2018. A loss of market share held by PDE5is, from $817m in 2018 to $301m in 2019, was largely attributable to this generic competition.

The guanylyl cyclase stimulator (GCS) class, which consists of a single asset, Adempas, is holding steady by stealing market share from the PDE5i class; however, this is limited to a minority of patients who respond poorly to PDE5is.

Johnson & Johnson’s two newer marketed brands, Opsumit and Uptravi, are projected to become the highest-selling products during the forecast period. Opsumit is the established market leader, with blockbuster sales of $1,639m in 2020. These two products will experience strong uptake, benefiting from physician familiarity, strong positioning in treatment guidelines, and robust efficacy data to support them. Importantly, Johnson & Johnson has generated efficacy data for morbidity/mortality, broadening the evidence base for its products. Although the results of the TRITON trial were largely negative, the triple combination therapy exhibited a numerical reduction in the risk of first disease progression event.

Despite PAH patients making up only 20% of the PH population, most therapies are targeted at this group, with off-label use of drugs for groups 2, 3, and 5 PH. The high rate of off-label use highlights a critical unmet need for approved therapies in these indications.

Increasing label expansions to include group 2-4 PH subtypes is a key area of interest and will be a major driver of growth in the PH market. Market leaders Opsumit and Uptravi are being investigated in clinical trials to potentially support label expansions to chronic thromboembolic pulmonary hypertension (CTEPH). This will bring new treatment options to underserved CTEPH patients who currently only have one approved therapy option, Adempas.

United Therapeutics’ application for a label expansion for injectable treprostinil, Tyvaso, to include group 3 PH patients, which will make it the first approved therapy for this subtype, is expected to receive a response in April 2021 from the FDA. Given the scarcity of competitors in non-PAH segments, there is a prominent opportunity for market penetration for these drugs.

The approval of pipeline candidates will diversify the PH market and meet an important unmet need to treat the underlying pathophysiology of the disease rather than just disease symptoms. Of the pipeline candidates in late-stage development, sotatercept, which targets the transforming growth factor beta (TGF) pathway to correct the underlying cause of the disease, is the most promising candidate and has been heralded as a game changer.

Other notable pipeline candidates include novel delivery systems such as INOpulse and Trevyent, which are set to revolutionize the delivery of nitric oxide and Remodulin. However, pipeline candidates will have an initially muted effect on the market due to strong physician familiarity with the established drug classes and the static nature of the PH market.
