Core Insights - The latest research confirms that Nefecon® significantly reduces kidney function deterioration by 50% through its positive effects on the first three hits in the "four-hit" model of IgA nephropathy [1][3][4]. Group 1: Efficacy and Mechanism - Nefecon® has been shown to significantly lower levels of Gd-IgA1, IgG anti-IgA antibodies, and IgA immune complexes (IgA-IC), indicating its effectiveness across multiple pathogenic pathways [1][3][4]. - Changes in Gd-IgA1 or polymeric IgA within the first two months of treatment are significantly correlated with reductions in proteinuria, suggesting these biomarkers could guide Nefecon® therapy [1][3][7]. - The NefIgArd trial involved 216 participants and demonstrated that Nefecon® effectively targets the gut to modulate immune responses, thereby reducing pathogenic IgA levels [4][5]. Group 2: Clinical Significance - Nefecon® is the first and only drug approved for the causal treatment of IgA nephropathy in China, the U.S., and Europe, and is recommended in multiple clinical guidelines, solidifying its position as a cornerstone therapy [2][4]. - The drug's ability to intervene at the source of IgA nephropathy's pathogenesis is expected to reshape treatment strategies and provide more options for a broader patient population [4]. Group 3: Patient Impact - In China, there are over 5 million patients with IgA nephropathy, with more than 100,000 new cases diagnosed annually, highlighting the significant healthcare burden and the need for effective treatments like Nefecon® [3].

第二项多中心研究聚焦分析伴不同病理表现的IgA肾病患者的治疗获益。结果显示，给予9个月的耐赋 康治疗后患者尿蛋白显著降低，肾功能（eGFR）保持稳定，且在伴有毛细血管内皮细胞增生（E1）和/ 或新月体形成（C1）的患者中，蛋白尿下降更显著。这一发现提示，这两种活动性病变可以积极使用 耐赋康治疗，且无论有无活动性病变，患者均可从治疗中维持eGFR稳定，保护肾功能。 在第62届欧洲肾脏协会（ERA 2025）大会上，耐赋康（布地奈德肠溶胶囊，NEFECON®）展示的两项 最新研究结果证实了耐赋康在不同基线肾功能水平患者中均取得卓越疗效，并揭示了其在全部不同病理 人群中的显著获益。作为全球首个且唯一在中国、美国和欧洲获得完全批准，且不受蛋白尿水平限制的 IgA肾病对因治疗药物，此次研究成果为"全部治疗"策略提供了坚实支持，证实耐赋康实现了IgA肾病全 人群肾脏保护。 耐赋康凭借创新的作用机制和临床优势，先后被纳入改善全球肾脏病预后组织（KDIGO）发布的 《2024版KDIGO IgA肾病和IgA血管炎临床管理实践指南（公开审查版）》，以及《中国成人IgA肾病 及IgA血管炎临床实践指南（预审版本）》。 两项研究证 ...
