Current treatments involve prolonged multidrug regimens with poor outcomes and significant side effects, highlighting the urgent need for improved therapies. Using a BALB\/c mouse model of chronic\n              <jats:italic>M. avium<\/jats:italic>\n              pulmonary disease, we evaluated the efficacy of individual antibiotics\u2014clarithromycin, clofazimine, and rifabutin\u2014and combination regimens including clarithromycin + bedaquiline and clarithromycin + clofazimine + bedaquiline. Clarithromycin demonstrated potent bactericidal activity, reducing lung bacterial burden by 2.2 log\n              <jats:sub>10<\/jats:sub>\n              CFU, while clofazimine transitioned from bacteriostatic to bactericidal, achieving a 1.7 log\n              <jats:sub>10<\/jats:sub>\n              CFU reduction. Rifabutin was bacteriostatic against\n              <jats:italic>M. avium<\/jats:italic>\n              MAC 101 but ineffective against MAC 104. The triple-drug regimen of clarithromycin + clofazimine + bedaquiline was the most effective, achieving a 3.3 log\n              <jats:sub>10<\/jats:sub>\n              CFU reduction in bacterial load, with 98% clearance within the first week and continued efficacy over 8 weeks. Gross pathology confirmed these results, with granulomatous lesions observed only in untreated or rifabutin-treated mice. Combination therapy demonstrated enhanced efficacy compared to monotherapy. The findings underscore the potential of oral clarithromycin + clofazimine + bedaquiline or clarithromycin + clofazimine regimen as a promising therapeutic strategy for\n              <jats:italic>M. avium<\/jats:italic>\n              pulmonary disease.\n            <\/jats:p>\n          <\/jats:sec>","DOI":"10.1128\/aac.01853-24","type":"journal-article","created":{"date-parts":[[2025,3,14]],"date-time":"2025-03-14T13:01:14Z","timestamp":1741957274000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":12,"title":["The efficacy of a regimen comprising clarithromycin, clofazimine, and bedaquiline in a mouse model of chronic\n            <i>Mycobacterium avium<\/i>\n            lung infection"],"prefix":"10.1128","volume":"69","author":[{"given":"Binayak","family":"Rimal","sequence":"first","affiliation":[{"name":"Division of Infectious Diseases, Department of Medicine, School of Medicine, Johns Hopkins University","place":["Baltimore, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth A.","family":"Howe","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Medicine, School of Medicine, Johns Hopkins University","place":["Baltimore, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chandra","family":"Panthi","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Medicine, School of Medicine, Johns Hopkins University","place":["Baltimore, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2214-0114","authenticated-orcid":true,"given":"Gyanu","family":"Lamichhane","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases, Department of Medicine, School of Medicine, Johns Hopkins University","place":["Baltimore, USA"]},{"name":"Center for Nontuberculous Mycobacteria and Bronchiectasis, School of Medicine, Johns Hopkins University","place":["Baltimore, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tube.2022.102267"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0038-1651491"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1080\/17476348.2021.1987891"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-018-3113-x"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.00798-2019"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciaa241"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccm.2023.06.009"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccm.2021.11.007"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1136\/thoraxjnl-2017-210927"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1513\/AnnalsATS.202008-925OC"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinthera.2019.08.010"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.04841-14"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.02349-19"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0311167"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.1093\/clinids\/20.5.1186"},{"key":"e_1_3_4_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jid.2017.09.031"},{"key":"e_1_3_4_18_2","doi-asserted-by":"publisher","DOI":"10.1128\/aac.01055-24"},{"key":"e_1_3_4_19_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.38.11.2521"},{"key":"e_1_3_4_20_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-023-48001-y"},{"key":"e_1_3_4_21_2","doi-asserted-by":"publisher","DOI":"10.3389\/fcimb.2023.1115530"},{"key":"e_1_3_4_22_2","doi-asserted-by":"publisher","DOI":"10.3390\/antibiotics13060475"},{"key":"e_1_3_4_23_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199309163291202"},{"key":"e_1_3_4_24_2","doi-asserted-by":"publisher","DOI":"10.1086\/514748"},{"key":"e_1_3_4_25_2","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dkw417"},{"key":"e_1_3_4_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tube.2022.102268"},{"key":"e_1_3_4_27_2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.00239-17"},{"key":"e_1_3_4_28_2","first-page":"313","volume-title":"Molecular Genetics of Mycobacteria","author":"Larsen M","year":"2000","unstructured":"Larsen M. 2000.
