Abstract

Background and aims: Primary biliary cholangitis is a rare, progressive liver disease. Obeticholic acid (OCA) received accelerated approval for treating patients with primary biliary cholangitis in whom ursodeoxycholic acid failed, based on a surrogate endpoint of reduction in ALP. Analysis of the long-term safety extension with 2 external control groups demonstrated a significant increase in event-free survival in OCA-treated patients. This fully real-world evidence study assessed the effect of OCA treatment on clinical outcomes.

Approach and results: This trial emulation used data from the Komodo Healthcare Map claims database linked to US national laboratory, transplant, and death databases. Patients with compensated primary biliary cholangitis and intolerance/inadequate response to ursodeoxycholic acid who initiated OCA therapy were compared with patients who were OCA-eligible but not OCA-treated. The primary endpoint was time to the first occurrence of death, liver transplant, or hospitalization for hepatic decompensation, analyzed using a propensity-score weighted Cox proportional hazards model. Baseline prognostic factors were balanced using standardized morbidity ratio weighting. For the primary analysis, 4174 patients contributed 11,246 control index dates, and 403 patients contributed OCA indexes. Weighted groups were well balanced. Median (95% CI) follow-up in the OCA and non-OCA arms was 9.3 (8.4-10.6) months and 17.5 (16.2-18.6) months (weighted population; censored at discontinuation). Eight events occurred in the OCA arm and 32 in the weighted control (HR = 0.37; 95% CI = 0.14-0.75; p < 0.001). Effects were consistent for each component of the composite endpoint.

Conclusions: We identified a 63% reduced risk of hospitalization for hepatic decompensation, liver transplant, or death in OCA-treated versus non-OCA-treated individuals.

奥比胆酸治疗原发性胆管炎的肝脏实际预后(HEROES):一项试验模拟研究设计。
背景和目的:原发性胆管炎(PBC)是一种罕见的进行性肝脏疾病。奥贝胆酸(OCA)获得加速批准,用于治疗熊脱氧胆酸(UDCA)治疗失败的PBC患者,基于碱性磷酸酶减少的替代终点。对2个外部对照组的长期安全性延长分析表明,oca治疗患者的无事件生存期显著增加。这项完全真实的证据研究评估了OCA治疗对临床结果的影响。方法和结果:该试验模拟使用了与美国国家实验室、移植和死亡数据库相关联的Komodo医疗保健地图™索赔数据库中的数据。开始OCA治疗的代偿性PBC和对UDCA不耐受/反应不足的患者与符合OCA条件但未接受OCA治疗的患者进行比较。主要终点是首次发生死亡、肝移植或因肝功能失代偿住院的时间,使用倾向评分加权Cox比例风险模型进行分析。采用标准化发病率加权法平衡基线预后因素。在初步分析中,4174例患者提供了11246个对照指标日期;403例患者贡献了OCA指数。加权分组很平衡。OCA组和非OCA组的中位随访(95% CI)分别为9.3(8.4-10.6)个月和17.5(16.2-18.6)个月(加权人群;停产时审查)。OCA组发生8例,加权对照组发生32例(HR=0.37;95%可信区间= 0.14 - -0.75;结论:我们发现,与未接受oca治疗的个体相比,接受oca治疗的个体因肝失代偿、肝移植或死亡住院的风险降低了63%。试验注册:HEROES;ClinicalTrials.gov NCT05292872。
