Cov Tshuaj Menin Inhibitors: Kev Kho Mob Tshiab rau Acute Myeloid Leukemia

Kab mob leukemia myeloid loj heev (AML) yog ib hom kab mob ntshav uas muaj ntau yam thiab sib txawv, uas yog los ntawm kev loj hlob ntawm cov hlwb myeloid progenitor. Txawm hais tias kev kho mob tau zoo los, kev kho AML tseem nyuaj, tshwj xeeb tshaj yog rau cov neeg mob uas muaj cov teeb meem caj ces tshwj xeeb. Cov kev tshawb fawb tsis ntev los no tau hais tawm hauv phau ntawv xov xwm. Ntshav qhia txog qhov tseem ceeb ntawm kev kho mob ntawm Menin inhibitors, qhia txog lawv lub peev xwm los hloov pauv kev kho mob AML.

Lub Luag Haujlwm ntawm Epigenetics hauv AML

Kev hloov pauv epigenetic, xws li DNA methylation thiab histone modification, yog cov kev hloov pauv uas rov qab tau uas tswj kev qhia tawm ntawm cov noob caj noob ces yam tsis hloov pauv cov DNA sequence. Cov kev hloov pauv no ua lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm AML. Kev tsom mus rau cov txheej txheem epigenetic uas rov qab tau no muab txoj hauv kev kho mob tshiab.

Histones, cov protein tseem ceeb hauv DNA ntim, raug hloov kho tom qab kev txhais lus xws li acetylation thiab methylation, uas cuam tshuam rau kev sau cov noob caj noob ces. Menin, ib qho protein scaffolding uas tau encoded los ntawm MEN1 gene, yog qhov tseem ceeb rau kev tswj hwm epigenetic. Nws cuam tshuam nrog histone methyltransferase KMT2A thiab lwm tus khub los tswj kev qhia noob caj noob ces. Hauv AML, Menin pab txhawb cov kev pab cuam sau cov noob caj noob ces oncogenic, tshwj xeeb tshaj yog los ntawm kev nce ntxiv ntawm HOXA thiab MEIS1 noob, uas yog cov tsav tsheb tseem ceeb hauv KMT2A-rearranged thiab NPM1-mutated AML.

Cov Tshuaj Menin Inhibitors: Kev Tshawb Fawb Tshiab hauv Kev Kho Mob AML

Cov tshuaj Menin inhibitors yog cov tshuaj me me uas xaiv tau zoo heev uas tsim los cuam tshuam kev sib cuam tshuam ntawm Menin thiab KMT2A, yog li ntawd thaiv cov txoj kev sau ntawv oncogenic. Cov tshuaj inhibitors no tau pom tias muaj txiaj ntsig zoo hauv kev tshawb fawb ua ntej thiab kev tshawb fawb hauv tsev kho mob, tshwj xeeb tshaj yog rau KMT2A-rearranged thiab NPM1-mutated AML, uas ua ke suav nrog ib pawg tseem ceeb ntawm cov neeg mob AML.

Tus thawj Menin inhibitor, revumenib (SNDX-5613), tau txais kev pom zoo rau kev siv hauv kev kho mob, nrog rau ntau lwm tus, suav nrog ziftomenib (KO-539) thiab bleximenib, uas tau raug sim hauv kev kho mob. Kev sim AUGMENT-101 tau qhia tias revumenib tau txais qhov feem pua ​​​​​​ntawm kev teb tag nrho (ORR) ntawm 53% hauv kev rov qab los lossis tsis kho (R/R) AML, nrog rau cov kev mob tshwm sim uas tswj tau xws li QTc ntev thiab kev sib txawv ntawm cov kab mob. Ib yam li ntawd, cov txiaj ntsig thaum ntxov los ntawm KOMET-001 thiab KOMET-008 kev sim ntsuas ziftomenib tau qhia txog cov nqi zam txim zoo thiab cov qauv kev nyab xeeb.

Kev kho mob ua ke kuj tseem tab tom tshawb nrhiav kom txhim kho qhov ua tau zoo ntawm Menin inhibitors. Cov kev tshawb fawb sib xyaw revumenib nrog cov neeg sawv cev hypomethylating xws li azacitidine thiab venetoclax tau tshaj tawm tias cov nqi teb yuav luag 100% rau cov neeg mob AML uas haum thiab tsis haum, txawm hais tias xav tau kev tshawb fawb ntxiv nrog cov pab pawg loj dua.

Kev Nyab Xeeb thiab Cov Lus Qhia Yav Tom Ntej

Cov tshuaj Menin inhibitors feem ntau muaj cov qauv kev nyab xeeb zoo, nrog rau feem ntau cov kev mob tshwm sim tuaj yeem tswj tau thiab rov qab tau. Cov teeb meem tshwm sim feem ntau suav nrog cov tsos mob ntawm txoj hnyuv plab, cytopenias, thiab differentiation syndrome. Cov kev xaiv kho mob tshiab uas tau tso cai los ntawm US FDA rau revumenib thiab ziftomenib qhia txog qhov tseem ceeb ntawm Menin inhibitors hauv kev daws cov kev xav tau tsis tau txais kev pab hauv kev kho mob AML.

Cov ntaub ntawv kho mob zoo txog Menin inhibitors yog ib kauj ruam hloov pauv hauv kev kho mob AML, muab kev cia siab rau cov neeg mob uas muaj keeb kwm nyuaj txog cov noob caj noob ces. Thaum kev tshawb fawb txuas ntxiv mus, cov kev kho mob no tau npaj txhij los txhais dua tus qauv ntawm kev kho mob rau AML.

BIOOCUS International Medical Center tseem cog lus tias yuav siv cov kev nce qib tshiab xws li Menin inhibitors los xa cov kev kho mob tshiab thiab zoo rau cov neeg mob thoob ntiaj teb.
