Background: This analysis compared effects of the activin signaling inhibitor, sotatercept, across pulmonary arterial hypertension (PAH) subgroups stratified by baseline cardiac index (CI).

Methods: Pooled data from PULSAR (N=106; NCT03496207) and STELLAR (N=323; NCT04576988) were analyzed using two different CI thresholds, < and ≥ 2.0 L/min/m or 2.

Article Synopsis
  • The STELLAR trial tested the drug sotatercept, showing it improved walking distance and other health measures in patients with pulmonary arterial hypertension (PAH).
  • Data from right heart catheterization and echocardiography were analyzed over 24 weeks to assess the drug's effects on heart and lung parameters.
  • Results indicated significant reductions in pulmonary artery pressure and resistance, along with improvements in right heart function, indicating sotatercept's potential effectiveness for PAH patients.

Article Synopsis
  • * A phase 3 clinical trial tested sotatercept against a placebo in adults with PAH who were already on stable therapy, focusing on improvements in exercise capacity measured by walking distance over a 24-week period, along with several secondary health measures.
  • * Results from the trial indicated that patients taking sotatercept had a significant improvement in their 6-minute walk distance compared to those on placebo, showing a median increase of 34.4 meters versus just
