Abemaciclib yog ib hom tshuaj kho qhov ncauj uas muaj nyob rau hauv chav kawm ntawm kev xaiv cyclin-dependent kinase 4/6 (CDK4/6) inhibitors, feem ntau yog siv los kho cov tshuaj hormone receptor-positive (HR+), HER2-negative mis Lesion cells. Nws ua haujlwm los ntawm inhibiting cov haujlwm ntawm CDK4 thiab CDK6, thaiv kev loj hlob ntawm G1 mus rau S theem ntawm lub voj voog ntawm tes, yog li inhibiting cell proliferation thiab kev loj hlob. Piv nrog rau lwm cov tshuaj hauv tib chav kawm, Abemaciclib qhia tau hais tias muaj zog InhibitionInhibition ntawm CDK4 thiab txhawb kev tswj xyuas tas li, ua kom pom kev ua tau zoo raws li kev kho mob monotherapy. Nws tuaj yeem siv ib leeg lossis ua ke nrog kev kho mob endocrine thiab tsim nyog rau kev kho mob ntxiv ntawm metastatic thiab siab - pheej hmoo ntxov - kab mob. Nws ib nrab-lub neej nyob rau hauv lub cev yog kwv yees li 1-2 lub lis piam, thiab tus neeg sib txawv thiab cov tshuaj cuam tshuam rau nws cov metabolism. Raws li kev tshawb fawb soj ntsuam txuas ntxiv mus, qhov ntau ntawm cov ntawv thov thiab cov tswv yim kho mob rau Abemaciclib tau hloov zuj zus mus tas li.
Abemaciclib, yog dab tsi
Abemaciclib hmoovyog ib qho khoom xyaw nquag (feem ntau hauv daim ntawv mesylate) siv los kho qee yam kab mob, tshwj xeeb tshaj yog cov tshuaj hormone receptor-positive (HR+) HER2-negative. Nws lub luag haujlwm tseem ceeb yog inhibit qhov kev loj hlob ntawm cov kab mob no. Nws yog cyclin -dependent kinase (CDK) inhibitor uas tshwj xeeb rau CDK4 thiab CDK6. CDKs yog cov catalysts uas tswj lub voj voog ntawm tes, thiab lawv cov haujlwm txawv txav feem ntau cuam tshuam nrog kev loj hlob thiab kev sib kis ntawm cov kab mob. Nws tau raug pom zoo los siv ua ke nrog ob peb lwm yam tshuaj los kho qee hom kab mob metastatic lossis cov kab mob siab heev ntawm lub mis.
Qee zaum, nws kuj tuaj yeem siv los ua ib tus neeg sawv cev. Nws yog ib qho tseem ceeb kom nco ntsoov tias cov lus qhia tshwj xeeb thiab muaj nyob ntawm cov tshuaj no tuaj yeem hloov pauv raws sijhawm. Yog tias koj lossis ib tus neeg koj paub tab tom txiav txim siab lossis tau txais kev kho mob uas muaj cov khoom xyaw no, nws yog ib qho tseem ceeb uas yuav tau sab laj nrog kws kho mob kom paub ntau tshaj - txog - hnub thiab cov ntaub ntawv tseeb txog nws cov kev siv, cov kev mob tshwm sim, thiab lwm yam ntaub ntawv ntsig txog raws li cov lus qhia kho mob thiab kev tshawb fawb tshiab.

Abemaciclib ua haujlwm li cas
Abemaciclib yog kev kho qhov ncauj qhov ncauj uas feem ntau kho cov tshuaj hormone receptor-positive (HR+), HER2-negative. Nws ua haujlwm los ntawm kev thaiv cov proteins tseem ceeb uas tsav cov cell faib.
Mechanism ntawm Action
1. CDK4/6 InhibitionInhibition
Cov tshuaj no xaiv inhibits cyclin -dependent kinases 4 thiab 6 (CDK4 thiab CDK6). Cov kinases no tseem ceeb heev rau cov hlwb kom nce qib ntawm G1 mus rau theem S ntawm lub voj voog ntawm tes.
2. Rb Protein Activation
Feem ntau, CDK4/6 phosphorylates retinoblastoma (Rb) protein, ua rau nws tsis ua haujlwm. Cov khoom no tiv thaiv qhov phosphorylation, ua kom Rb protein ua haujlwm.
3. Cell Cycle Arrest
Active Rb protein inhibits E2F transcription yam, uas yog tsim nyog rau DNA synthesis. Qhov no ua rau G1 theem cell voj voog raug ntes, tiv thaiv cell faib.
4. Kev loj hlob ntawm cov qog nqaij hlav qeeb
Los ntawm kev tiv thaiv cell proliferation, qhov kev loj hlob ntawm Lesion cells qeeb los yog nres. Nyob rau tib lub sijhawm, cov hlwb tuaj yeem ua rau lub cev tsis muaj zog lossis apoptosis.
Dab tsi Ua Abemaciclib Cim Ntawm CDK4/6 Inhibitors
Muaj zog Inhibition ntawm CDK4 tshaj CDK6
Kev noj tshuaj tas mus li (tsis muaj hnub so tshuaj noj)
Muaj zog ib leeg -tus neeg ua haujlwm
Kev siv tshuaj kho mob
Nws tuaj yeem siv ib leeg lossis ua ke nrog kev kho mob endocrine
Pom zoo rau: Metastatic HR + / HER2- lub mis Lesion cells. (adjuvant therapy).
Abemaciclib nyob hauv lub cev ntev npaum li cas
Cov khoom no tseem nyob hauv lub cev li ntawm 1-2 lub lis piam tom qab koob tshuaj kawg. Hauv qab no yog ib txoj kev kwv yees:
Ib nrab -lub neej
Qhov nruab nrab tshem tawm ib nrab - lub neej ntawm abemacclib yog kwv yees li 18-25 teev.
Kev tshem tawm ntawm lub cev
Cov tshuaj raug tshem tawm tau zoo tom qab kwv yees li 5 ib nrab-lub neej.
Qhov no txhais tau tias: Feem ntau ntawm cov tshuaj raug tshem tawm hauv 4-6 hnub; nyob ze ntawm kev tshem tawm tag nrho: mus txog 7-10 hnub;
Abemaciclib muaj cov metabolites nquag, uas tuaj yeem ua kom ntev me ntsis nws cov teebmeem lom txawm tias niam txiv cov tshuaj concentration txo qis. Kev tshem tshuaj yeeb yuav qeeb yog tias muaj cov xwm txheej hauv qab no:
Kev sib cuam tshuam tshuaj (tshwj xeeb tshaj yog CYP3A inhibitors, txiv kab ntxwv qaub, thiab lwm yam)
Lub raum ua haujlwm tsis tshua muaj kev cuam tshuam rau kev tshem tawm tshuaj ntau dua li kev ua haujlwm siab.
Pharmacological teebmeem feem ntau yuav txo qis hauv ob peb hnub.
Lub sij hawm nyob rau hauv lub cev: Kwv yees li 1 lub lis piam, tej zaum mus txog 2 lub lis piam nyob rau hauv ib co neeg.
Puas yog Abemaciclib ua rau hnyav nce
Cov lus teb yog tias cov khoom no feem ntau tsis ua rau qhov hnyav nce, thiab qhov hnyav nce tsis yog qhov tshwm sim los yog xav tau.
Yuav ua li cas feem ntau tshwm sim?
Hauv kev sim tshuaj thiab kev siv tiag tiag - ntiaj teb no, cov neeg mob muaj feem yuav poob phaus dua qhov hnyav dua. Qhov no feem ntau yog los ntawm cov tsos mob xws li raws plab (feem ntau), tsis qab los noj mov, xeev siab, thiab qaug zog.
Cov kev mob tshwm sim no txo qis calorie kom tsawg, tshwj xeeb tshaj yog nyob rau theem pib ntawm kev kho mob.
Yuav ua li cas txog cov lus ceeb toom ntawm qhov hnyav nce?
Qee tus neeg mob tau tshaj tawm qhov hnyav nce, tab sis qhov no feem ntau yog qhov tsis ncaj, tsis yog qhov cuam tshuam ncaj qha ntawm cov tshuaj: qhov hnyav nce feem ntau yog tshwm sim los ntawm cov yam ntxwv xws li kev kho tshuaj hormone siv ua ke nrog abemaciclib, txo qis kev ua haujlwm vim qaug zog, kev hloov pauv metabolic cuam tshuam nrog menopause, lossis txhim kho qab los noj mov tom qab zawv plab.
Cov khoom nws tus kheej tsis ua rau muaj rog ntau lossis qeeb metabolism.
