PROJECT SUMMARY/ABSTRACT Patent ductus arteriosus (PDA), the most common cardiovascular condition in preterm infants, is associated with mortality and harmful longer-term outcomes including chronic lung disease (CLD) and brain injury. Although treatment does not benefit all infants with PDA, likely due to spontaneous closure, treatment of some infants with symptomatic PDA is necessary. Medications are often used to close persistent preterm PDA in the initial four weeks postnatal, but fail to close the PDA in 1/3 of infants, in whom an intervention is the only remaining definitive closure option (failed pharmacological management). A treatment dilemma exists in the first postnatal month for the subset of infants with persistent, hemodynamically significant, and clinically symptomatic PDA (HSPDA) after postnatal week one following failed pharmacological management. Invasive, intrathoracic PDA surgery was tra- ditionally employed for infants with HSPDA, but associations between surgery and adverse neurodevelopment prompted widespread adoption of non-interventional, supportive treatment. This watchful-waiting approach avoids or delays procedure-related complications, but prolongs developing brain and lung exposure to PDA- related hemodynamics. Evidence is emerging that duration of HSPDA exposure is an important predictor of CLD and/or death. Percutaneous catheter-based closure (PPC) is a novel, minimally-invasive means of closing a HSPDA. A duct occluder (ADO-II AS) was recently approved (1/2019) by the US FDA for preterm infants weigh- ing ≥700 grams. However, the effectiveness of PPC in improving important neonatal outcomes relative to sup- portive (non-intervention) HSPDA management has never been evaluated via a randomized trial (RCT). The uncertainty is whether PPC should be performed early (days 7-30 postnatal) for all infants with HSDPA to prevent PDA-related complications or only rarely as a last resort following a prolonged trial of supportive management. The objective in this application is to determine if PPC improves cardiopulmonary and neurodevelopmental out- comes via a multicenter RCT comparing the two strategies. Aim 1 will determine the effect of PPC versus sup- portive treatment on ventilator-free days (VFDs) at 30 days post-randomization (non-survivors will be scored as having zero VFDs). Aim 2 will determine the effect of PPC versus supportive treatment on secondary cardiopul- monary, safety and neurodevelopmental outcomes. Aim 3 will evaluate whether neurodevelopment at 3-4 months corrected age is mediated by improved neurodevelopmental profiles at 34-36 weeks postmenstrual age. Aim 4 will evaluate potential effect modifiers of HDPSA (e.g., sex, race/ethnicity, gestational age, age at ran- domization) on VFDs and secondary outcomes. This trial will immediately advance the care of extremely preterm infants with HSPDA following failed medical management by identifying whether PPC or supportive treatment better improves cardiopulmonary and neurodevelopmental outcomes.

项目概要/摘要 动脉导管未闭 (PDA) 是早产儿最常见的心血管疾病，与 死亡率和有害的长期结果，包括慢性肺病（CLD）和脑损伤。 治疗并不能使所有患有 PDA 的婴儿受益，可能是由于自然闭合，对一些患有 PDA 的婴儿进行治疗 有症状的 PDA 是必要的，通常会在最初的 4 个月内使用药物来关闭持续性早产 PDA。 产后几周，但 1/3 的婴儿未能闭合 PDA，其中干预是唯一有效的方法 关闭选项（药物治疗失败）在产后第一个月存在治疗困境。 患有持续性、血流动力学显着且有临床症状的 PDA (HSPDA) 的婴儿亚群 出生后第一周，药物治疗失败后，进行了侵入性胸腔内 PDA 手术。 通常用于患有 HSPDA 的婴儿，但手术与不良神经发育之间存在关联 促使人们广泛采用非干预性支持治疗。 避免或延迟手术相关并发症，但会延长发育中的大脑和肺部暴露于 PDA 的时间 相关的血流动力学证据表明，HSPDA 暴露时间是 CLD 的重要预测因素。 经皮导管封堵术 (PPC) 是一种新颖的微创封堵方法。 HSPDA。导管封堵器 (ADO-II AS) 最近被美国 FDA 批准 (1/2019) 用于早产儿体重 ≥700 克 然而，相对于支持，PPC 在改善重要新生儿结局方面的有效性。 从未通过随机试验 (RCT) 评估过主动（非干预）HSPDA 管理。 不确定的是是否应该对所有患有 HSDPA 的婴儿尽早（产后 7-30 天）进行 PPC 以预防 PDA 相关并发症或很少作为长期支持性治疗试验后的最后手段。 本申请的目的是确定 PPC 是否可以改善心肺和神经发育输出 通过多中心 RCT 比较这两种策略，目标 1 将确定 PPC 与支持的效果。 随机分组后 30 天无呼吸机日 (VFD) 的局部治疗（非幸存者将被评分为 目标 2 将确定 PPC 与支持治疗对继发性心肺功能的影响。 目标 3 将评估 3-4 岁的神经发育情况。 月数校正年龄是通过经后 34-36 周时神经发育状况的改善而介导的。 目标 4 将评估 HDPSA 的潜在影响因素（例如性别、种族/族裔、胎龄、随机年龄） domization）对 VFD 和次要结果的影响 该试验将立即推进极早产儿的护理。 通过确定是 PPC 还是支持治疗，治疗失败后患有 HSPDA 的婴儿 更好地改善心肺和神经发育结果。
