We evaluated the efficacy and safety of nebulized tobramycin inhalation solution (TIS) in adults with bronchiectasis with&nbsp;<em>Pseudomonas aeruginosa<\/em>&nbsp;infection.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Research Question<\/h3>\n\n\n\n<p>Can TIS effectively reduce sputum&nbsp;<em>P&nbsp;aeruginosa<\/em>&nbsp;density and improve the bronchiectasis-specific quality of life in patients with bronchiectasis with&nbsp;<em>P&nbsp;aeruginosa<\/em>&nbsp;infection?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Study Design and Methods<\/h3>\n\n\n\n<p>This was a phase 3, 16-week, multicenter, randomized, double-blind, placebo-controlled trial. Eligible adults with bronchiectasis were recruited from October 2018 to July 2021. On the basis of usual care, patients nebulized TIS (300&nbsp;mg\/5&nbsp;mL twice daily) or normal saline (5&nbsp;mL twice daily) via vibrating-mesh nebulizer. Treatment consisted of two cycles, each consisting of 28&nbsp;days on-treatment and 28&nbsp;days off-treatment. The coprimary end points included changes from baseline in&nbsp;<em>P&nbsp;aeruginosa<\/em>&nbsp;density and Quality-of-Life Bronchiectasis Respiratory Symptoms score on day&nbsp;29.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Results<\/h3>\n\n\n\n<p>The modified intention-to-treat population consisted of 167 patients in the tobramycin group and 172 patients in the placebo group. Compared with placebo, TIS resulted in a significantly greater reduction in\u00a0<em>P\u00a0aeruginosa<\/em>\u00a0density (adjusted mean difference, 1.74 log<sub>10<\/sub>\u00a0colony-forming units\/g; 95%\u00a0CI, 1.12-2.35;\u00a0<em>P<\/em>\u00a0&lt; .001) and greater improvement in Quality-of-Life Bronchiectasis Respiratory Symptoms score (adjusted mean difference, 7.91; 95%\u00a0CI, 5.72-10.11;\u00a0<em>P<\/em>\u00a0&lt; .001) on day 29. Similar findings were observed on day 85. TIS resulted in a significant reduction in 24-h sputum volume and sputum purulence score on days 29, 57, and 85. More patients became culture negative for\u00a0<em>P\u00a0aeruginosa<\/em>\u00a0in the tobramycin group than in the placebo group on day 29 (29.3%\u00a0vs\u00a010.6%). The incidence of adverse events and serious adverse events were comparable between the two groups.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/ars.els-cdn.com\/content\/image\/1-s2.0-S0012369222012478-fx1_lrg.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/ars.els-cdn.com\/content\/image\/1-s2.0-S0012369222012478-gr1_lrg.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/ars.els-cdn.com\/content\/image\/1-s2.0-S0012369222012478-gr2_lrg.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/ars.els-cdn.com\/content\/image\/1-s2.0-S0012369222012478-gr3_lrg.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/ars.els-cdn.com\/content\/image\/1-s2.0-S0012369222012478-gr4_lrg.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Interpretation<\/h3>\n\n\n\n<p>TIS is an effective treatment option and has an acceptable safety profile in patients with bronchiectasis with&nbsp;<em>P&nbsp;aeruginosa<\/em>infection.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Trial Registration<\/h3>\n\n\n\n<p>ClinicalTrials.gov; No. NCT03715322; URL:&nbsp;<a href=\"https:\/\/www.clinicaltrials.gov\/\">www.clinicaltrials.gov<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>CHEST INFECTIONS: ORIGINAL RESEARCH|&nbsp;VOLUME 163, I [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[32,23],"tags":[],"_links":{"self":[{"href":"https:\/\/csccm.org.cn\/index.php?rest_route=\/wp\/v2\/posts\/24419"}],"collection":[{"href":"https:\/\/csccm.org.cn\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/csccm.org.cn\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/csccm.org.cn\/index.php?rest_route=\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/csccm.org.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=24419"}],"version-history":[{"count":1,"href":"https:\/\/csccm.org.cn\/index.php?rest_route=\/wp\/v2\/posts\/24419\/revisions"}],"predecessor-version":[{"id":24420,"href":"https:\/\/csccm.org.cn\/index.php?rest_route=\/wp\/v2\/posts\/24419\/revisions\/24420"}],"wp:attachment":[{"href":"https:\/\/csccm.org.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=24419"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/csccm.org.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=24419"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/csccm.org.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=24419"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
