超短期疗程贝达喹啉、氯法齐明、吡嗪酰胺和德拉马尼与药物敏感结核病的标准疗法 (PRESCIENT)
超短期疗程贝达喹啉、氯法齐明、吡嗪酰胺和地拉马尼与药物敏感结核病标准疗法 (PRESCIENT) 的 IIc 期、开放标签、随机对照试验
PRESCIENT 试验是一项 IIc 期、开放标签、随机试验,将比较贝达喹啉 (BDQ)、氯法齐明 (CFZ)、吡嗪酰胺 (PZA) 和地拉马尼 (DLM) 的 8 周方案与药物敏感患者的标准治疗方案肺结核。 符合条件的参与者将以 1:1 的比例随机接受 BDQ、CFZ、PZA 和 DLM (BCZD) 或标准抗结核治疗。
在治疗结束时有证据表明临床反应不佳的实验组参与者将接受标准 TB 治疗的再次治疗。 主要分析是实验 (BCZD) 组与标准治疗组在 8 周内液体培养转化时间的优效性比较。 另一个关键的次要结果是安全性。

详细说明
PRESCIENT 试验是一项 IIc 期、开放标签、随机试验,将比较贝达喹啉 (BDQ)、氯法齐明 (CFZ)、吡嗪酰胺 (PZA) 和地拉马尼 (DLM) 的 8 周方案与药物敏感患者的标准治疗方案肺结核。 符合条件的参与者将以 1:1 的比例随机接受 BDQ、CFZ、PZA 和 DLM (BCZD) 或标准抗结核治疗。 将根据肺空化和 HIV 状态的存在对随机化进行分层。
参与者将被随机分配到两个臂之一:
第 1 组(实验):BDQ 200 mg 8 周 + PZA 1000 - 2000 mg(根据体重)8 周 + CFZ 300 mg 2 周,随后 100 mg 6 周 + DLM 200 mg 8 周,全部每天一次。
第 2 组(标准治疗):RIF、INH、EMB 和 PZA 8 周,然后是 RIF 和 INH 18 周。
药物将按标准体重剂量每天以固定剂量组合给药。 依从性将通过自动提醒得到支持,并使用 Wisepill 电子依从性监测设备进行远程实时监测。 实验组的参与者在治疗结束时有临床反应不佳的证据,定义为与活动性结核病一致的持续症状、胸部 X 光片显示疾病无改善或恶化,或两个样本的痰涂片阳性,将重新接受治疗。接受标准结核病治疗,以及在第 8 周或之后收集的 Mtb 培养呈阳性的患者。 主要分析是实验 (BCZD) 组与标准治疗组在 8 周内液体培养转化时间的优效性比较。 参与者将在随机分组后 56 周(完成实验治疗后 48 周,预计大多数复发发生时)进行延长的治疗后随访,以评估临床疗效作为次要综合结果指标。 另一个关键的次要结果是安全性,以新的 3 级或更高级别不良事件的比例衡量;我们将把 QTcF 延长作为一种特别感兴趣的不良事件来关注。 通过高效的 IIc 期设计, PRESCIENT 试验将测试微生物功效,评估安全性,并检测超短 BCZD 方案的治疗紧急耐药性。 PRESCIENT 将提供微生物有效性的快速证据以及安全性和临床治疗结果的关键信息,以告知后续 III 期缩短治疗试验的可行性和前景。

Time to positivity in liquid culture is defined as the days required for a sample to exhibit detectable microbial growth (positive result) in liquid media.
A shorter time to positivity indicates a higher concentration of viable microorganisms in the original sample.
Participants with a negative liquid culture result were imputed to have the 'best' time to positivity of 43 days (>42 days), and participants with contaminated culture results were excluded.
Sputum samples were collected at weeks 1, 2, 3, 4, 6, and 8 for culture in liquid media.
