Data Sources: A PubMed search was performed using the term neratinib between September 12, 2018, and November 21, 2018. References of published articles and reviews were also assessed for additional information. Study Selection and Data Extraction: English-language preclinical and clinical studies on the chemistry, pharmacology, pharmacokinetics, safety, and efficacy of neratinib were evaluated. Data Synthesis: Neratinib, an irreversible inhibitor of HER1, HER2, and HER4, is Food and Drug Administration approved for the extended adjuvant treatment of stage I-III HER2+ BC to follow trastuzumab-based therapy. A phase III study has demonstrated statistically significant improvement in 5-year disease-free survival rate (90.2 vs 87.7; hazard ratio = 0.73, 95% CI = 0.57-0.92, P = 0.0083). Its most common adverse effect is diarrhea, observed in more than 90% of patients. The incidence of grade 3\/4 diarrhea (~40%) is reduced by half with loperamide prophylaxis, which is recommended for the first 8 weeks of neratinib therapy. Other common adverse reactions are nausea and fatigue. The patients need to be monitored for liver function tests and drug interactions with acid-reducing agents, CYP3A4 inhibitors\/inducers, and P-glycoprotein substrates with narrow therapeutic window. Relevance to Patient Care and Clinical Practice: American Society of Clinical Oncology and National Comprehensive Cancer Network clinical guidelines suggest the use of neratinib for extended adjuvant therapy following 1-year trastuzumab in stage I to III HER2+ BC. Diarrhea remains a clinically significant but manageable adverse event. Conclusion: Neratinib significantly improves treatment outcomes and has manageable toxicity in stage I to III HER2+ BC patients.<\/jats:p>","DOI":"10.1177\/1060028018824088","type":"journal-article","created":{"date-parts":[[2019,1,4]],"date-time":"2019-01-04T05:33:56Z","timestamp":1546580036000},"page":"612-620","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":28,"title":["Neratinib in HER2-Positive Breast Cancer Patients"],"prefix":"10.1177","volume":"53","author":[{"given":"Rutugandha","family":"Paranjpe","sequence":"first","affiliation":[{"name":"University of Houston College of Pharmacy, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dima","family":"Basatneh","sequence":"additional","affiliation":[{"name":"University of Houston College of Pharmacy, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Tao","sequence":"additional","affiliation":[{"name":"University of Houston College of Pharmacy, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmine","family":"De Angelis","sequence":"additional","affiliation":[{"name":"Lester and Sue Smith Breast Center, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sobia","family":"Noormohammed","sequence":"additional","affiliation":[{"name":"University of Houston College of Pharmacy, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8606-6179","authenticated-orcid":false,"given":"Ekim","family":"Ekinci","sequence":"additional","affiliation":[{"name":"Houston Methodist Hospital, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan","family":"Abughosh","sequence":"additional","affiliation":[{"name":"University of Houston College of Pharmacy, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romi","family":"Ghose","sequence":"additional","affiliation":[{"name":"University of Houston College of Pharmacy, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0585-5580","authenticated-orcid":false,"given":"Meghana V.","family":"Trivedi","sequence":"additional","affiliation":[{"name":"University of Houston College of Pharmacy, Houston, TX, USA"},{"name":"Lester and Sue Smith Breast Center, Houston, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,1,4]]},"reference":[{"key":"bibr1-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1097\/PAP.0000000000000015"},{"key":"bibr2-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1016\/j.critrevonc.2017.10.001"},{"key":"bibr3-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1016\/j.ctrv.2016.11.002"},{"key":"bibr4-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdt217"},{"key":"bibr5-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1186\/bcr3621"},{"key":"bibr6-1060028018824088","doi-asserted-by":"publisher","DOI":"10.14694\/EdBook_AM.2015.35.e157"},{"key":"bibr7-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1016\/j.ctrv.2013.09.002"},{"key":"bibr8-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1016\/j.ctrv.2018.04.016"},{"key":"bibr9-1060028018824088","doi-asserted-by":"publisher","DOI":"10.14694\/EDBK_15916710.1200\/EDBK_159167"},{"key":"bibr10-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1021\/jm040159c"},{"key":"bibr11-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1158\/0008-5472.CAN-03-2868"},{"key":"bibr12-1060028018824088","doi-asserted-by":"publisher","DOI":"10.1002\/ardp.200800009"},{"key":"bibr13-1060028018824088","unstructured":"Nerlynx [package insert].
