Ingufu nyinshi zo kuvura CD7 CAR-T ku ndwara za B-cell: Iterambere mu kuvura kanseri
Ubushakashatsi buheruka bwerekana akamaro n'umutekano wa CD7 CAR-T selile mu kuvura kanseri y'amaraso ya B-cell acute lymphoblastic leukemia (B-ALL) yasubiwemo cyangwa itarakira na T-cell lymphoblastic lymphoma (T-LBL). Ubu bushakashatsi bwakozwe na BIOOCUS ku bufatanye n'ibitaro bya Lu Daopei, bugaragaza umusaruro mwiza ku barwayi, butanga ubundi buryo bukomeye bwo kuvura kanseri busanzwe.
Mu iterambere rishimishije kuri Ubuvuzi bwa kanseri, BIOOCUS, ku bufatanye n'ibitaro bya Lu Daopei, bashyize ahagaragara ubushakashatsi bukomeye ku ikoreshwa rya CD7 chimeric antigen receptor (CAR) T-cell therapy. Ubu buryo bushya, bugamije gusubira inyuma cyangwa kwangirika kwa B-cell acute lymphoblastic leukemia (B-ALL) na T-cell lymphoblastic lymphoma (T-LBL), bugaragaza imikorere myiza n'umutekano, butuma umusaruro w'abarwayi urushaho kuba mwiza cyane.
Ubushakashatsi bwasohotse mu kinyamakuru gikomeye, bwagaragaje igereranya ry’abarwayi bahabwaga ubuvuzi bwa CD7 CAR-T, hanyuma bugashyirwa hamwe n’ubuvuzi bwa allogeneic hematopoietic hematopoietic stem transplantation (allo-HSCT) ugereranije n’abavuwe na chemotherapy mbere yo guterwa ubuvuzi. Ibyavuye mu bushakashatsi bigaragaza ko abarwayi babashije kurokoka burundu (CR) bakoresheje ubuvuzi bwa CD7 CAR-T bagize ingaruka zo kubaho igihe kirekire nk’iz’abavuwe na chemotherapy isanzwe. Icy'ingenzi ni uko ubushakashatsi bwagaragaje ko nta bwiyongere bugaragara bw’ibibazo nyuma yo guterwa ubuvuzi, nk’indwara ya graft-versus-host (GVHD), indwara zandura, cyangwa izindi ngaruka mbi.
Ingingo z'ingenzi z'ubushakashatsi zirimo:
- Igipimo cyuzuye cyo kurekurwa: Uburyo bwo kuvura CD7 CAR-T bwagaragaje igipimo gitangaje cyo koroherwa burundu, aho abarwayi barenga 97% bitabiriye neza ubwo buvuzi.
- Umwirondoro w'umutekano: Nubwo habayeho uburyo bushya bwo gukoresha CAR-T therapy, ubuvuzi bwaranzwe neza, ingaruka mbi zabwo zikaba nke cyane kandi nta kwiyongera gukomeye kwa GVHD cyangwa izindi ngorane zikomeye.
- Intsinzi nyuma yo guterwa: Abarwayi bakorewe isuzuma rya allo-HSCT nyuma yo kugera ku buvuzi bwa CR bakoresheje CD7 CAR-T bagaragaje ko babayeho neza muri rusange (OS) kandi bagakomeza kubaho nta maraso bafite mu maraso (LFS), nk'uko byagereranywa n'ubuvuzi gakondo bushingiye ku miti ikoreshwa mu kuvura kanseri.
Ubu bushakashatsi bugaragaza intambwe ikomeye mu rwego rwo Ubuvuzi bw'ubudahangarwa bwa kanseri, itanga icyizere ku barwayi bafite kanseri y'amaraso na kanseri y'amaraso yongeye kugaruka cyangwa idashobora kuvura. BIOOCUS ikomeje kwiyemeza guteza imbere imipaka y'ubuvuzi bwa CAR-T, itanga ibisubizo bishya ku barwayi barangije uburyo busanzwe bwo kuvura. Mu gihe isi yose ikomeje kwakira ubu buryo bugezweho bwo kuvura, BIOOCUS iri ku isonga mu guteza imbere uburyo bwo kuvura buzana impinduka nyazo ku musaruro w'abarwayi.
