美国联合医疗（United Therapeutics）宣布，其针对间质性肺病（ILD）患者开展的TETON-2三期临床研究已达到主要终点。数据显示，治疗52周后，使用Tyvaso（曲前列尼尔）吸入溶液的患者在绝对用力肺活量（FVC）指标上表现出具有统计学意义的显著改善。
这项随机双盲安慰剂对照研究，旨在评估Tyvaso在改善ILD患者肺功能方面的疗效与安全性。绝对FVC作为衡量肺功能恢复程度的核心指标，其积极结果验证了Tyvaso对于延缓疾病进展的临床价值。
研究结果进一步强化了Tyvaso在肺动脉高压及ILD治疗领域的地位，为拓展其适应症提供关键数据支持。公司表示将基于该研究结果与全球监管机构进行沟通，推动Tyvaso在更多地区的临床应用。
