Kuchiza Koyambirira ndi Chithandizo cha CAR-T cha Lymphoma Yaikulu ya B-Cell Kukuwonetsa Zotsatira Zabwino

Kafukufuku waposachedwapa wokhudza zakale wofalitsidwa mu Kusamutsa Mafuta a Bone BoneKafukufuku wafufuza momwe chithandizo cha maselo a CAR-T chimagwirira ntchito msanga poyerekeza ndi mochedwa mwa odwala omwe ali ndi vuto lalikulu la matenda a shuga. B-Cell Lymphoma (LBCL). Kafukufukuyu adachitika m'malo atatu ku US ndi Israel, ndipo adakhudza odwala 354 omwe adalandira chithandizo cha CAR-T choyang'aniridwa ndi CD19 pakati pa Epulo 2016 ndi Marichi 2024. Cholinga cha kafukufukuyu chinali kuwunika momwe kupereka chithandizo cha CAR-T ngati chithandizo chachiwiri (chithandizo choyambirira) kumakhudzirana ndi chithandizo chachitatu kapena chamtsogolo (chithandizo chochedwa) cha LBCL yobwereranso kapena yosagwira ntchito.

Zotsatira zake zasonyeza kuti kupereka chithandizo cha CAR-T koyambirira, ngakhale kuti vuto la chotupa cha wodwalayo linali lochepa komanso chitetezo chamthupi chinali chabwino, kunali ndi zotsatira zabwino. Chiwerengero chonse cha anthu omwe adachiritsidwa pambuyo pa chaka chimodzi chinali 87% pa chithandizo choyambirira ndi 82% pa chithandizo cha mochedwa, ngakhale kuti kusiyana sikunali kofunikira kwambiri pa ziwerengero (p=0.3). Komabe, chiwerengero chonse cha anthu omwe adapulumuka (OS) chinali chokwera kwa gulu loyambirira la chithandizo, ndipo 82% adapulumuka chaka chimodzi poyerekeza ndi 71% ya gulu lochedwa la chithandizo (p=0.048).

Chochititsa chidwi n'chakuti, kafukufukuyu sanapeze kusiyana kwakukulu pakati pa magulu awiriwa pankhani ya kupulumuka popanda kupita patsogolo (PFS), kuchuluka kwa kubwereranso m'mbuyo, kapena kufa chifukwa cha chithandizo. Kuwonjezeka kwa kubwereranso m'mbuyo kwa chaka chimodzi kunali 37% kwa gulu loyambirira ndi 43% kwa gulu lomaliza, popanda kusintha kwakukulu kuchokera nthawi yoperekedwa kwa CAR-T (p=0.2). Kafukufukuyu adapezanso kuti kuchuluka kwa cytokine release syndrome (CRS) ya giredi 2 kapena kuposerapo kunali kotsika kwambiri m'gulu loyambirira la chithandizo (26%) poyerekeza ndi gulu lomaliza la chithandizo (39%) (p=0.031), zomwe zikusonyeza kuti kulowererapo koyambirira kungachepetse poizoni wina wokhudzana ndi chithandizo.

Zomwe zapezekazi zikuthandizira kugwiritsa ntchito mankhwala a CAR-T ngati chithandizo chachiwiri cha LBCL, chifukwa amatha kupewa mavuto okhudzana ndi chithandizo chamtsogolo, kuphatikizapo kuchepa kwa kulekerera chifukwa cha thanzi la wodwalayo kapena kutopa kwa maselo a T. Kafukufukuyu akugogomezeranso kufunika kofufuza kwina kuti amvetsetse njira zamoyo zotsutsana ndi CAR-T komanso kufufuza njira zochiritsira zosakaniza kuti ziwongolere zotsatira m'magawo onse a chithandizo.

Ngakhale kuti kafukufukuyu ndi woganizira zakale ndipo akhoza kukhala ndi tsankho komanso kutsatira pang'ono, zotsatira zake zimapereka chidziwitso chofunikira pa nthawi yoyenera yothandizira odwala a CAR-T. Zomwe zapezekazi zikusonyeza kuti kuchitapo kanthu mwachangu pogwiritsa ntchito chithandizo cha CAR-T kungathandize kupulumuka ndikuchepetsa poizoni, zomwe zimapangitsa kuti pakhale njira yofunika kwambiri yopititsira patsogolo njira zothandizira khansa yovutayi.
