Muhimman Abubuwan da aka Gano

Binciken ya tantance marasa lafiya 47, inda 23 (48.9%) suka kamu da cutar APB bayan maganin CAR-T. Mafi yawan nau'in IgG shine (91.3%). Matsakaicin lokacin da aka fara APB shine watanni 3.6 bayan allurar CAR-T, kuma matsakaicin tsawon lokacin shine watanni 5.8. Abu mafi mahimmanci, faruwar APB yana da alaƙa da ingantaccen martanin magani, tsawon rayuwa ba tare da ci gaba ba (PFS), da kuma ingantaccen rayuwa gabaɗaya (OS).

Ƙarin bayanai sun haɗa da:

• Ingantaccen Sakamakon AsibitiMarasa lafiya da ke fama da APB sun nuna kyakkyawan sakamako ga maganin LCAR-B38M kuma sun sami ƙarin sassauci mai zurfi.

Abin sha'awa, binciken bai gano wani muhimmin bambanci ba a cikin ƙananan ƙwayoyin T ko ƙwayoyin NK tsakanin ƙungiyoyin APB da waɗanda ba APB ba, yana nuna cewa ƙimar hasashen APB na iya samo asali ne daga ingantaccen murmurewa daga humoral da garkuwar jiki maimakon hanyoyin garkuwar jiki.
