Major phase I and phase II clinical trials established the efficacy and safety of fam-trastuzumab deruxtecan-nxki for treatment of HER2-positive advanced, unresectable, or metastatic breast cancers that are refractory or intolerant to standard treatment. In these trials, the response rate was 60.9% (95% CI = 53.4-68.0) Common adverse effects included fatigue, nausea, vomiting, decreased appetite, constipation, diarrhea, alopecia, neutropenia, anemia, and thrombocytopenia. Serious adverse effects included interstitial lung disease or pneumonia, febrile neutropenia, left ventricular dysfunction, and embryo-fetal toxicity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Relevance to Patient Care and Clinical Practice:<\/jats:title>\n                    <jats:p>Fam-trastuzumab deruxtecan-nxki is an option for HER2-positive breast cancer following 2 previous lines of HER2-targeted therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Fam-trastuzumab deruxtecan-nxki is an effective treatment for HER2-positive breast cancer in the metastatic setting, but randomized controlled trials are needed.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1060028021998320","type":"journal-article","created":{"date-parts":[[2021,2,25]],"date-time":"2021-02-25T06:15:59Z","timestamp":1614233759000},"page":"1410-1418","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["A Review of Fam-Trastuzumab Deruxtecan-nxki in HER2-Positive Breast Cancer"],"prefix":"10.1177","volume":"55","author":[{"given":"Xoan","family":"Nguyen","sequence":"first","affiliation":[{"name":"Oregon State University, Corvallis, OR, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8440-3442","authenticated-orcid":false,"given":"Morgan","family":"Hooper","sequence":"additional","affiliation":[{"name":"Oregon State University, Corvallis, OR, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jared Paul","family":"Borlagdan","sequence":"additional","affiliation":[{"name":"Oregon Health and Science University, Portland, OR, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alison","family":"Palumbo","sequence":"additional","affiliation":[{"name":"Oregon Health and Science University, Portland, OR, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,2,25]]},"reference":[{"key":"bibr1-1060028021998320","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21583"},{"key":"bibr2-1060028021998320","doi-asserted-by":"publisher","DOI":"10.1158\/1055-9965.EPI-17-0627"},{"key":"bibr3-1060028021998320","doi-asserted-by":"publisher","DOI":"10.37765\/ajmc.2020.42900."},{"key":"bibr4-1060028021998320","unstructured":"Enhertu.
