Postmarketing analysis of sotatercept: identifying serious unlabelled events.
Article in Open heart, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeSotatercept, an activin signalling inhibitor approved in March 2024 for pulmonary arterial hypertension (PAH), demonstrated efficacy in clinical trials. This pharmacovigilance study evaluated its real-world safety profile using the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) to identify postmarketing risks.
methodsFAERS reports from 2024 were analysed, focusing on cases where sotatercept was designated as the primary suspect. Duplicate entries were removed using standardised FDA protocols. Adverse events (AEs) were categorised using the Medical Dictionary for Regulatory Activities (MedDRA V.28.0). Disproportionality signals were assessed via reporting ORs (RORs; 95% CI lower limit >1 with ≥3 cases). Severity was classified using the EudraVigilance Important Medical Events (IMEs) list.
resultsAmong 1 484 350 deduplicated reports, 613 sotatercept-associated AEs (1717 occurrences, 395 MedDRA terms) were identified. Disproportionality analysis revealed 48 safety signals: 30 aligned with labelled risks (eg, haemoglobin elevation (ROR=272.2), telangiectasia (ROR=334.1)) and 18 novel signals. The most frequent AEs included headache (n=78), epistaxis (n=57) and diarrhoea (n=53). Two unlabelled events-cerebral haemorrhage and ascites-met criteria for critical IMEs. Most reports originated from the USA (98.5%) and involved females (73.6%).
conclusionThis study confirms sotatercept's labelled risks (haematological and vascular effects) and identifies novel safety concerns, including cerebral haemorrhage and ascites, highlighting the need for vigilant monitoring in PAH management. Real-world data underscore the value of postmarketing surveillance for detecting rare or unanticipated AEs. Clinicians should prioritise monitoring for haematological abnormalities and bleeding risks. Longitudinal studies are warranted to clarify long-term safety outcomes.
