A common toxicity, diarrhea was well-managed with loperamide prophylaxis.[4] Adverse effectsNeratinib can cause life-threatening diarrhea in some people and mild to moderate diarrhea in almost everyone; people who take it are also at risk for complications of diarrhea like dehydration and electrolyte imbalance.[3] Similarly there is a risk of severe liver damage and many patients have some level of it; symptoms of liver damage include fatigue, nausea, vomiting, right upper quadrant pain or tenderness, fever, rash, and high levels of eosinophils.[3] In addition to the above, more than 10% of people taking it have nausea, abdominal pain, vomiting, sores on their lips, stomach upset, decreased appetite, rashes, and muscle spasms.[3] InteractionsPeople taking neratinib should not also take gastric acid reducing agents including proton pump inhibitors and H2-receptor antagonists; antacids may be used three hours before of after taking it.[3] Drugs that inhibit CYP3A4 increase the activity of neratinib and can make adverse effects worse, and drugs that induce CYP3A4 make neratinib less active and can reduce its efficacy. Neratinib also inhibits p-glycoprotein and effectively raises the dose of drugs like digoxin that depend on it for elimination.[3] PharmacologyLike lapatinib and afatinib, it is a dual inhibitor of the human epidermal growth factor receptor 2 (Her2) and epidermal growth factor receptor (EGFR) kinases.[5][6] It inhibits them by covalently binding with a cysteine side chain in those proteins.[7] Neratinib has an IC50 of 59 nM against HER2 and shows weak inhibition against KDR and Scr with IC50 values of 0.8 µM and 1.4 µM, respectively. In BT474 cells, neratinib reduces HER2 autophosphorylation, and inhibited cyclin D1 expression while reduced proliferation has been observed A431 cells when treated with neratinib at concentrations of 3 or 5 nM. In xenograft models with 3T3/neu tumors oral administration of neratinib at 10, 20, 40 or 80 mg/kg was able to inhibit tumor growth while in SK-OV-3 models doses of 5 and 60 mg/kg significantly inhibited tumor growth.[8] ChemistryNeratinib is a 4-anilino-3-cyano quinoline derivative. [3] HistoryNeratinib was discovered and initially developed by Wyeth; Pfizer continued development up to Phase III in breast cancer, and licensed it to Puma Biotechnology in 2011.[9] In September 2016 Puma submitted a new drug application to the US FDA for neratinib as a treatment for some people with HER-2 positive breast cancer.[10] In July 2017 it was approved by the US FDA for adjuvant treatment of adult patients with early stage HER2-overexpressed/amplified breast cancer, (after adjuvant trastuzumab-based therapy).[11] In January 2018 an EMA committee gave a negative review to neratinib.[12][13] References1. ^{{cite web|title=Neratinib|url=http://adisinsight.springer.com/drugs/800021154|publisher=AdisInsight|access-date=22 May 2017|language=en}} {{Extracellular chemotherapeutic agents}}{{Growth factor receptor modulators}}2. ^{{cite web |url=http://www.cancer.gov/Templates/drugdictionary.aspx?CdrID=453548 |title=Definition of neratinib - National Cancer Institute Drug Dictionary |format= |website= |access-date=2008-12-01}} 3. ^1 2 3 4 5 6 7 8 {{cite web|title=Neratinib tablets label|url=https://www.accessdata.fda.gov/drugsatfda_docs/label/2017/208051s000lbl.pdf|publisher=FDA|date=July 2017|access-date=6 February 2018}} For label updates see, [https://www.accessdata.fda.gov/scripts/cder/daf/index.cfm?event=overview.process&varApplNo=208051 FDA index page for NDA 208051] 4. ^{{cite journal |vauthors= Gandhi L, et al. |title= MA04.02 Neratinib ± Temsirolimus in HER2-mutant lung cancers: an international, randomized phase II study |url= http://www.jto.org/article/S1556-0864(16)31639-2/fulltext |journal= Journal of Thoracic Oncology |volume= 12 |issue= 1 |pages= S358-9 |doi= 10.1016/j.jtho.2016.11.398|year= 2017 }} 5. ^{{cite journal | vauthors = Baselga J, Coleman RE, Cortés J, Janni W | title = Advances in the management of HER2-positive early breast cancer | journal = Critical Reviews in Oncology/Hematology | volume = 119 | pages = 113–122 | date = November 2017 | pmid = 29042085 | pmc = 5662944 | doi = 10.1016/j.critrevonc.2017.10.001 }} 6. ^{{cite journal | vauthors = Minami Y, Shimamura T, Shah K, LaFramboise T, Glatt KA, Liniker E, Borgman CL, Haringsma HJ, Feng W, Weir BA, Lowell AM, Lee JC, Wolf J, Shapiro GI, Wong KK, Meyerson M, Thomas RK | display-authors = 6 | title = The major lung cancer-derived mutants of ERBB2 are oncogenic and are associated with sensitivity to the irreversible EGFR/ERBB2 inhibitor HKI-272 | journal = Oncogene | volume = 26 | issue = 34 | pages = 5023–7 | date = July 2007 | pmid = 17311002 | doi = 10.1038/sj.onc.1210292 }} 7. ^{{cite journal | vauthors = Singh J, Petter RC, Baillie TA, Whitty A | title = The resurgence of covalent drugs | journal = Nature Reviews.
