The DEPTH trial represents an innovative approach to slowing the progression of emphysema in people living with HIV (PLWH), a population that has accelerated disease progression for which there is no targeted therapy. With our CCC collaborators, we propose a phase II, multi-center, randomized, double-blind, placebo-controlled trial of doxycycline 100 mg po BID to slow the progression of emphysema as quantified by diffusing capacity for carbon monoxide (DLCO) among PLWH who are current or former smokers. Participants will be stratified by smoking status (current vs former smoker) and clinical site, utilizing dynamic randomization. The primary endpoint of the study is the rate of decline (slope) of percent predicted DLco corrected for hemoglobin, carboxyhemoglobin and barometric pressure over the 72-week treatment period. Our clinical collaborators have successfully demonstrated the feasibility of this study in their NHLBI-funded pilot study to test the safety and tolerability of doxycycline in 27 individuals over 24 weeks (NCT 01744093), and have assembled a group of experienced clinical sites. The DEPTH trial will extend their promising pilot data to a formal phase II clinical trial. An experienced data coordinating center (DCC) with strong statistical leadership and expertise is key in both design and analysis, particularly when unanticipated issues arise during the conduct of a clinical trial. The University of Michigan (UM) Statistical Analysis of Biomedical and Educational Research (SABER) unit in a top-ranked department of biostatistics will serve as DCC, bringing together an experienced group of faculty and staff in biostatistics, project management, study monitoring, database design and data management, software development, and research administration. SABER has a strong track record of collaborations with Weill Cornell Medicine pulmonary team as the clinical coordinating center (CCC). The overarching goal of the UM DCC is to collaborate with study investigators, the CCC, and NHLBI to enable successful achievement of the study on time and within budget. We will accomplish these goals through the three specific aims: (1) Enhance scientific rigor by providing statistical and clinical trials methodological expertise to design, analyze, and disseminate research findings; (2) Ensure the collection of timely, accurate and reproducible data, and maximize adherence to the study protocol; and (3) Provide established infrastructure and services for study administration and operations and for communication among study stakeholders. Our leadership, experience, and expertise will promote collaborations, encourage scientific productivity, and facilitate timely dissemination of findings on the benefits of doxycycline in PLWH who have emphysema. We anticipate that upon completion of this proposed study, our data will support repurposing the inexpensive antibiotic doxycycline, to slow emphysema progression in PLWH, and demonstrate that it is safe and well tolerated.

深度试验代表了一种降低肺气肿进展的创新方法 患有艾滋病毒（PLWH）的人，该人口加速了疾病进展 靶向疗法。与我们的CCC合作者一起，我们提出了II期，多中心，随机，双盲， 多西环素的安慰剂对照试验100 mg bid降低了肺气肿的进展 当前或以前吸烟者的PLWH中，一氧化碳（DLCO）的能力扩散。参与者 利用动态随机化，将根据吸烟状况（当前与前吸烟者）和临床部位进行分层。 该研究的主要终点是校正了预测DLCO百分比的下降速率（斜率） 在72周治疗期间，血红蛋白，羧基血红蛋白和气压压力。我们的临床 合作者在其NHLBI资助的试点研究中成功证明了这项研究的可行性 在27个个人中测试27个人中强力霉素的安全性和耐受性（NCT 01744093），并具有 组装了一组经验丰富的临床部位。深度试验将将其有希望的飞行员数据扩展到 正式II期临床试验。 具有强大统计领导和专业知识的经验丰富的数据协调中心（DCC）是关键 设计和分析都在进行临床试验期间出现意外问题时。这 密歇根大学（UM）生物医学和教育研究（SABER）单位的统计分析 排名最高的生物统计学部将担任DCC，将一群经验丰富的教职员工和 生物统计学，项目管理，研究监控，数据库设计和数据管理，软件的员工 发展和研究管理。 Saber与Weill合作有着良好的记录 康奈尔医学肺动队担任临床协调中心（CCC）。 UM的总体目标 DCC将与研究调查员，CCC和NHLBI合作，以成功实现 按时间和预算范围内学习。我们将通过三个特定目标来实现这些目标：（1）增强 科学严格的严格性通过提供统计和临床试验来设计，分析和 传播研究结果； （2）确保收集及时，准确和可重复的数据，以及 最大程度地遵守研究方案； （3）为研究提供既定的基础设施和服务 行政和运营以及研究利益相关者之间的沟通。我们的领导，经验， 专业知识将促进合作，鼓励科学生产力并促进及时传播 关于具有肺气肿的PLWH中强力霉素的好处的发现。我们预计完成后 在这项拟议的研究中，我们的数据将支持重新利用廉价的抗生素强力霉素，以减缓 PLWH中的肺气肿进展，并证明它是安全且耐受性的。
