Faamatalaga Afatinib

Afatinib, faʻatau atu i lalo ole igoa igoa Gilotrif faʻatasi ai ma isi, o se vailaʻau na faʻaaogaina e togafitia ai non-cell cell lung carcinoma (NSCLC). E ona le tyrosine kinase inhibitor aiga o vailaʻau. E ave e le gutu. E masani ona faʻaaoga e togafitia ai mataupu o le NSCLC o loʻo taofia fesuiaʻiga i le epidermal tuputupu aʻe mea maua (EGFR) gene.

Afatinib (BIBW2992), o le le mafai ona toe faʻafitia le aiga ErbB o tyrosine kinases, na faʻaalia e taofi le EGF-faʻasolosolo phosphorylation o EGFR ma sela faʻateleina i le tele o EGFR-overexpressing ma HER2-faʻaalia laina laina e pei o A431, NIH-3T3- HER2, NCI-N87 ma le BT-474.

O le vaega na faʻatele foi ona faʻaaogaina i manu eseʻese e suʻesuʻe ai le sao o le EGFR / HER2. Tautala tuʻuina o afatinib taofiofia kanesa sela tuputupu ae ma ola ma taofi le tuma faʻafitauli i xenograft ma transgenic mama kanesa faʻataʻitaʻiga. I se faʻaopopoga, afatinib ua faʻailoa o le EGFR blocker lea na faʻamaonia mo le togafitia o tagata mamaʻi ma EGFR-mutated nonsmall sela mama kanesa.

 

Afatinib Faiga o Gaioiga

E pei o le lapatinib ma le neratinib, o le afatinib o le poloka kinase e taofia ai ma e le mafai ai ona toe taofia le faʻatupuina o le tupuola o le tino i luga o le tino (2) ma le faʻaolaola o mea tutupu (EGFR).

Afatinib e le gata o faʻagaoioia ma le EGFR suiga na faʻatulagaina e le augatupulaga muamua tyrosine-kinase inhibitors (TKI) pei o le erlotinib poʻo le gefitinib, ae faʻapea foʻi ma le laʻititi o suiga masani e teteʻe i nei vailaʻau.

Ae ui i lea, e le o faʻagaioia faʻasaga i le T790M suiga e masani ona manaʻomia ai le isi augatupulaga lona tolu vailaʻau pei o le osimertinib. Ona o lona faʻaopopo gaioiga faʻasaga ia Her2, o lea ua suʻesuʻeina mo kanesa o le susu faʻapea foi ma isi EGFR ma Her2 faʻamalosi kanesa.

 

Afatinib Talosaga

Afatinib o se gaioiga bioavailable anilino-quinazoline derivative ma inhibitor o le receptor tyrosine kinase (RTK) epidermal tuputupu ae receptor (ErbB; EGFR) aiga, ma antineoplastic gaioiga.

Afatinib foi o se tautala tuʻufaʻatasia bioavailable lua receptor tyrosine kinase (RTK) taofia ma ono antineoplastic gaioiga. EGFR / HER2 tyrosine kinase inhibitor BIBW 2992 e le mafai ona toe fusifusia ma taofia le faʻatupulaia e tagata o le epidermal tuputupu aʻe vaega 1 ma le 2 (EGFR-1; HER2), lea e ono mafua ai le taofiofia o le tuputupu ae tuputupu ae ma angiogenesis. EGFR / HER2 o RTKs e ona le aiga EGFR; o loʻo i ai uma matafaioi taua i le faʻatupulaia o sela sela ma fula vascularization ma ua ova ona faʻamatalaina i le tele o ituaiga kanesa sela.

Afatinib ua faʻamaonia i le tele o le lalolagi (aofia ai le Iunaite Setete, Kanata, Peretania ma Ausetalia) mo le togafitiga o metastatic le-laiti sela sela kanesa (NSCLC), atiina ae e Boehringer Ingelheim. E avea o se angiokinase taofia.

 

Afatinib Itu Aafiaga & Lapataiga

O itu ole itu e masani ai (e tupu tele atu ile 30%) mo tagata mamaʻi e ave afatinib:

▪ Manava

▪ Fuafua paʻu (vaega o paʻu tulaga e pei o fuafua)

▪ Ogaoga o le gutu

▪ Paronychia (faʻamaʻi o fao)

▪ Gutu mago

 

Nei e le masani masani aʻafiaga (tupu i le 10-29%) mo tagata mamaʻi mauaina afatinib:

▪ Faʻaitiitia le fiaai

▪ O le mageso

▪ Leiloa o le pauna

▪ Ua tafetoto le isu

▪ Cystitis (faʻamaʻi pipisi)

▪ Cheilitis (mumu o laugutu)

▪ Fiva

▪ Hypokalemia (maualalo potasiuma)

▪ Conjunctivitis (mata piniki)

▪ Rhinorrhea (isu o le isu)

▪ Maualuga gaʻo o le ate

E le o aʻafiaga uma e lisi atu i luga. Nisi e seasea (tupu i lalo ifo o le 10 pasene o tagata mamaʻi) e le o lisiina iinei. Faʻailoa i taimi uma lau tautua faʻafomaʻi pe a fai e te iloa ni faʻailoga iloga.

 

Mea taua e manatua e uiga i le itu aʻafiaga o afatinib:

▪ Tele o tagata e le maua uma aafiaga afatinib afaina lisiina.

▪ Afatinib afaina o aʻafiaga e masani ona vaʻaia i tulaga o latou amataga, umi, ma ogaoga.

▪ Afatinib afaina o aʻafiaga e toeititi lava a suia ma o le a mou pe a maeʻa togafitiga.

▪ Afatinib afaina aʻafiaga ono mafai ona foʻia. E tele filifiliga e faʻaititia pe puipuia ai faʻafitauli o le afatinib.
