Clinical and cost-effectiveness of epoprostenol, iloprost, bosentan, sitaxentan and sildenafil for pulmonary arterial hypertension within their licensed indications: a systematic review and economic evaluation
Abstract
OBJECTIVE(S): To investigate the clinical and cost-effectiveness of epoprostenol, iloprost, bosentan, sitaxentan and sildenafil for the treatment of adults with pulmonary arterial hypertension (PAH) within their licensed indications. DATA SOURCES: Major electronic databases (including the Cochrane Library, MEDLINE and EMBASE) were searched up to February 2007. Further data were obtained from dossiers submitted to NICE by the manufacturers of the technologies. REVIEW METHODS: The systematic clinical and economic reviews were conducted according to accepted procedures. Model-based economic evaluations of the cost-effectiveness of the technologies from the perspective of the UK NHS and personal social services were carried out. RESULTS: In total, 20 randomised controlled trials (RCTs) were included in this assessment, mostly of 12-18 weeks duration and comparing one of the technologies added to supportive treatment with supportive treatment alone. Four published economic evaluations were identified. None produced results generalisable to the NHS. There was no consensus in the industry submissions on the most appropriate model structure for the technology assessment. Improvement in 6-minute walk distance (6MWD) was seen with intravenous epoprostenol in primary pulmonary hypertension (PPH) patients with mixed functional class (FC) (mainly III and IV, licensed indication) compared with supportive care (58 metres; 95% CI 6-110). For bosentan compared with supportive care, the…
