皮质类固醇注射治疗膝关节骨性关节炎因其治疗效果持续时间不长而受到限制。地塞米松磷酸钠的脂质体制剂(TLC599)是为持续缓解骨关节炎疼痛而研发的。

皮质类固醇注射治疗膝关节骨性关节炎因其治疗效果持续时间不长而受到限制。地塞米松磷酸钠的脂质体制剂(TLC599)是为持续缓解骨关节炎疼痛而研发的。近日,发表于Arthritis Res Ther的一项随机、双盲、安慰剂对照研究评估了TLC599在两种剂量水平下对膝关节骨性关节炎患者的疗效和安全性。

这项研究在13个研究中心开展,共纳入了75名膝关节骨性关节炎患者,将其随机分配并接受TLC599或安慰剂的单次关节内注射,评估干预治疗24周的疗效和安全性。患者报告的结果包括西安大略和麦克马斯特大学关节炎(WOMAC)疼痛和功能指数以及疼痛的视觉模拟量表。

 

结果显示,与安慰剂相比,12mg的TLC599在12周内(最小二乘法(LS)平均差=-0.37,p=0.0027)和24周内(LS平均差=-0.35,p=0.0037)的WOMAC疼痛明显减少。与安慰剂相比,TLC599 12mg在24周时表现出明显的功能改善(LS平均差异=-0.26,P = 0.0457)。然而,与安慰剂相比,TLC599 18mg没有明显改善患者的疼痛或功能。研究期间,与安慰剂相比,TLC599组患者对乙酰氨基酚的使用都比较少。两组都没有重大或意外安全问题的报告。

综上所述,该研究结果表明,在有症状的膝关节骨性关节炎患者中,TLC599可提供持久的疼痛缓解和功能改善,同时在远远超出目前治疗方案的时间段内保持令人满意的安全性。需要在有足够种族多样性的更大规模的III期研究中进行验证,以证实报告的结果。
