Compelling data have linked disease progression in patients with idiopathic pulmonary fibrosis (IPF) with lung dysbiosis and the resulting dysregulated local and systemic immune response. Moreover, prior therapeutic trials have suggested improved outcomes in these patients treated with either sulfamethoxazole/ trimethoprim or doxycycline. These trials have been limited by methodological concerns. This trial addresses the primary hypothesis that long-term treatment with antimicrobial therapy increases the time-to-event endpoint of respiratory hospitalization or all-cause mortality compared to usual care treatment in patients with IPF. We invoke numerous innovative features to achieve this goal, including: 1) utilizing a pragmatic randomized trial design; 2) collecting targeted biological samples to allow future exploration of ‘personalized’ therapy; and 3) developing a strong partnership between the NHLBI, a broad range of investigators, industry, and philanthropic organizations. The trial will randomize approximately 500 individuals in a 1:1 ratio to either antimicrobial therapy or usual care. The site principal investigator will declare their preferred initial antimicrobial treatment strategy (trimethoprim 160 mg/ sulfamethoxazole 800 mg twice a day plus folic acid 5 mg daily or doxycycline 100 mg once daily if body weight is < 50 kg or 100 mg twice daily if ≥50 kg) for the participant prior to randomization. Participants randomized to antimicrobial therapy will receive a voucher to help cover the additional prescription drug costs. Additionally, those participants will have 4–5 scheduled blood draws over the initial 24 months of therapy for safety monitoring. Blood sampling for DNA sequencing and genome wide transcriptomics will be collected before therapy. Blood sampling for transcriptomics and oral and fecal swabs for determination of the microbiome communities will be collected before and after study completion. As a pragmatic study, participants in both treatment arms will have limited in-person visits with the enrolling clinical center. Visits are limited to assessments of lung function and other clinical parameters at time points prior to randomization and at months 12, 24, and 36. All participants will be followed until the study completion for the assessment of clinical endpoints related to hospitalization and mortality events. ClinicalTrials.gov identifier NCT02759120.

多中心,实用,开放标签的抗微生物治疗随机试验的设计和原理-特发性肺纤维化(CleanUP-IPF)临床试验中采用实用设计进行抗微生物治疗策略的临床疗效研究。

令人信服的数据已将特发性肺纤维化(IPF)患者与肺功能不全症以及由此引起的局部和全身免疫反应失调联系起来。此外,先前的治疗试验表明,这些用磺胺甲恶唑/甲氧苄氨嘧啶或多西环素治疗的患者的转归改善。这些试验受到方法论问题的限制。该试验解决了以下主要假设:与IPF患者进行常规治疗相比,长期进行抗菌治疗会增加呼吸系统住院或全因死亡率的事件终点。我们调用众多创新功能来实现这一目标,包括:1)利用实用的随机试验设计;2)收集有针对性的生物样本,以便将来探索“个性化”疗法;3)在NHLBI,广泛的调查员,行业和慈善组织之间建立牢固的合作关系。该试验将以1:1的比例将大约500名患者随机分配至抗微生物治疗或常规护理。现场主要研究人员将宣布他们首选的初始抗菌治疗策略(甲氧苄啶160 mg /磺胺甲恶唑800 mg,每天两次,加上叶酸,每天5 mg,或多西环素,每天一次,如果体重<50 kg,如果体重小于或等于50,则每天两次,如果≥50公斤),然后随机分配给参与者。随机接受抗微生物治疗的参与者将获得一张优惠券,以帮助支付额外的处方药费用。此外,这些参与者将在治疗的最初24个月内抽血4-5次,以进行安全性监测。治疗前将收集用于DNA测序和全基因组转录组学的血样。在完成研究之前和之后,将收集转录组学,口腔和粪便拭子的血样以确定微生物组。作为一项务实的研究,两个治疗部门的参与者都只能在注册临床中心进行有限的亲自拜访。随访仅限于在随机分组之前的时间点以及在第12、24和36个月评估肺功能和其他临床参数。所有参与者将被随访直至研究完成,以评估与住院和死亡事件相关的临床终点。ClinicalTrials.gov标识符NCT02759120。在完成研究之前和之后,将收集转录组学,口腔和粪便拭子的血样以确定微生物组。作为一项务实的研究,两个治疗部门的参与者都只能在注册临床中心进行有限的亲自拜访。随访仅限于在随机分组之前的时间点以及在第12、24和36个月评估肺功能和其他临床参数。所有参与者将被随访直至研究完成,以评估与住院和死亡事件相关的临床终点。ClinicalTrials.gov标识符NCT02759120。在完成研究之前和之后,将收集转录组学,口腔和粪便拭子的血样以确定微生物组。作为一项务实的研究,两个治疗部门的参与者都只能在注册临床中心进行有限的亲自拜访。随访仅限于在随机分组之前的时间点以及在第12、24和36个月评估肺功能和其他临床参数。所有参与者将被随访直至研究完成,以评估与住院和死亡事件相关的临床终点。ClinicalTrials.gov标识符NCT02759120。两个治疗部门的参与者都只能在注册临床中心进行有限的面对面拜访。随访仅限于在随机分组之前的时间点以及在第12、24和36个月评估肺功能和其他临床参数。所有参与者将被随访直至研究完成,以评估与住院和死亡事件相关的临床终点。ClinicalTrials.gov标识符NCT02759120。两个治疗部门的参与者都只能在注册临床中心进行有限的面对面拜访。随访仅限于在随机分组之前的时间点以及在第12、24和36个月评估肺功能和其他临床参数。所有参与者将被随访直至研究完成,以评估与住院和死亡事件相关的临床终点。ClinicalTrials.gov标识符NCT02759120。
