A study on the accessibility and utilisation of targeted drugs for pulmonary arterial hypertension in China.
(PubMed, Front Pharmacol)
- "Among all drugs, treprostinil had the highest availability (56.1% across hospitals), while newer drugs such as selexipag had very low availability (3,700 CNY)...Drug accessibility exhibited significant structural imbalances, with some drugs being "affordable but hard to obtain" (e.g., riociguat) and others "highly burdensome and poorly accessible" (e.g., treprostinil). The findings demonstrate significant improvements in the affordability and availability of PAH-targeted therapies over the study period; however, notable inequalities persist in accessibility improvements across urban and rural areas and income groups. Future policies should be tailored to address specific accessibility challenges for different drug categories and focus on overcoming medication access barriers for low-income rural populations to foster health equity."

Case Report: Immune checkpoint inhibitor-associated pulmonary hypertension.
(PubMed, Front Cardiovasc Med)
- "We report a case of a 65-year-old male who developed severe pulmonary arterial hypertension (PAH) following treatment with the programmed cell death protein 1 inhibitor tislelizumab. Following the initiation of a triple combination targeted therapy for PAH comprising macitentan, riociguat, and treprostinil, the patient's condition improved significantly...To date, no specific diagnostic or treatment guidelines exist for this condition due to its rarity. Therefore, there is an urgent need for more case reports, shared experiences, and clinical research to assist clinicians in identifying optimal strategies for the diagnosis and management of this complication."

Targeting the Stromal Switch: Single-cell profiles implicate the cGMP-PKG pathway in driving fibrosis and cancer progression in Ulcerative Colitis
(ECCO-IBD 2026)
- "We established a murine model mimicking UC progression through cyclic dextran sulfate sodium (DSS) exposure with azoxymethane (AOM) initiation, evaluating the therapeutic effects of riociguat and sildenafil...Conclusion Our study provides a comprehensive single-cell atlas of the fibrotic and neoplastic UC microenvironment, establishing stromal cGMP-PKG signaling as a pivotal driver of disease progression. We demonstrate the therapeutic potential of repurposing cGMP-elevating drugs, offering a novel strategy to combat devastating UC complications."

Current Perspectives on Balloon Pulmonary Angioplasty for Chronic Thromboembolic Pulmonary Hypertension.
(PubMed, J Clin Med)
- "Recent randomized controlled trials, including the RACE and MR-BPA trials, have demonstrated that BPA results in greater reduction in pulmonary vascular resistance and mean pulmonary arterial pressure compared to riociguat, although with a higher incidence of procedure-related complications...This review synthesizes current evidence on the efficacy, safety, and practical aspects of BPA, while highlighting ongoing challenges, including long-term outcome data, standardization of treatment endpoints, and the role of combination therapy. BPA is poised to play an increasingly central role in personalized care strategies for CTEPH."

Global Resource Disparities Between Pulmonary Hypertension Centers: Results From the International Survey by the PVRI IDDI Access to Care Workstream.
(PubMed, Pulm Circ)
- "Phosphodiesterase type 5 (PDE-5) inhibitors were available in almost all centers but there was limited access to oral, inhaled, and parenteral prostacyclin therapy, riociguat, and selexipag. Survey results suggest significant disparities across the globe. Further research is needed to understand access to PH care and therapies in non-expert/academic centers and regional disparities within countries."

Design and Optimization of LOXL2 and sGC Dual-Target Regulators Targeting Extracellular Matrix Dysregulation and Vasodilation for the Treatment of Pulmonary Arterial Hypertension.
(PubMed, J Med Chem)
- "In a hypoxia-induced PAH rat model, its esterified derivative 9k markedly alleviated vascular remodeling and reduced pulmonary artery pressure, showing efficacy comparable to the combination of riociguat and PAT-1251. Consequently, this study proposes a novel strategy for the development of bifunctional PAH drugs, with a focus on extracellular matrix dysfunction and vasoconstriction, and has identified a promising lead compound."

Exercise capacity and oxygen saturation on six-minute walk testing relate to markers of organ dysfunction in adults with sickle cell disease
(ASH 2025)
- "We used the baseline clinical data from the STERIO-SCDprospective, randomized placebo-controlled Phase 1-2 clinical trial of riociguat for treatment of high-riskpatients with SCD to investigate this hypothesis. Data were obtained as part of the multi-center STERIO-SCD clinical trial... Patients with SCD and systemic hypertension, an elevated TRV and/or proteinuria reflectiveof end-organ damage exhibit lower exercise capacity and ambulatory oxygen saturations. Reducedexercise capacity and oxygen desaturation are associated with a greater degree of organ dysfunction.This suggests that end-organ disease plays a role in limitations of the observed reduced functionalcapacity in patients with SCD and that 6MWT may be a way of identifying higher risk patients who requirefurther evaluation for evidence of cardiopulmonary and renal disease."

Long-term effects of medical treatment in patients with chronic thromboembolic pulmonary hypertension.

- "The objective of the current pre-specified analysis was to evaluate the effect of medical treatment, including the approved oral guanylate cyclase stimulator (sGC) riociguat, in patients with or without mechanical intervention...This international CTEPH registry suggests that, although an increasing proportion of patients with CTEPH benefited from mechanical treatment, medical treatment with sGC may be associated with a survival advantage in patients undergoing BPA or no intervention. These observations confirm the results of previous randomised controlled trials in a real-world setting."

Vascular diameter and responsiveness to soluble guanylate cyclase modulators: A systematic review of preclinical and clinical evidence.

Future work should implement standardized vessel classification, rigorous biospecimen handling, and transparent methodological documentation to clarify the clinical significance of vessel diameter in sGC-based therapy."

Soluble guanylate cyclase induces cranial vasodilation and headache in adults: a randomized trial.
(PubMed, Brain Commun)
- "We evaluated whether oral ingestion of riociguat, a stimulator of soluble guanylate cyclase, could elicit cranial vasodilation and headache in healthy adults...These findings support the hypothesis that cranial vasodilation mediated via direct soluble guanylate cyclase stimulation contributes to headache pathogenesis. Further research is warranted to delineate the relative contributions of nitric oxide-dependent versus nitric oxide-independent soluble guanylate cyclase activation, and to evaluate guanylate cyclase signalling as a potential therapeutic target in headache disorders."

Comparing bridging therapies prior to balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension
(BTS WM 2025)
- "Medical therapies including phosphodiesterase-5 inhibitors (PDE5i), endothelin receptor antagonists (ERA) and riociguat are commonly used as bridging therapies to BPA, but data comparing these therapies are limited...These differences persisted following correction for baseline differences. As improvements in haemodynamic parameters are associated with improved BPA safety profile, bridging with dual therapy may enhance BPA safety, although more work is needed to validate this hypothesis."

Marked improvement in severe pulmonary arterial hypertension following airway infection in a patient with a heterozygous BMP9 nonsense mutation: a case report.

A patient with severe, treatment-resistant pulmonary hypertension exhibiting a dramatic improvement in pulmonary pressure following an AI is exceedingly rare. The present case may provide new insights into the pathophysiology of PAH."
