TRAIL-R2 and HER2 Bi-Specific Chimeric Antigen Receptor (CAR) T Cells for the Treatment of Metastatic Breast Cancer
Bu Faz 1 (Phase 1) gen aktarımı (gene transfer) çalışması, hem HER2'yi hem de TRAIL-R2'yi tanıyacak şekilde kimerik antijen reseptörü (chimeric antigen receptor, CAR) eklenmiş T hücreleri olan HTR2 T hücrelerini HER2 ifade eden (HER2-expressing) metastatik meme kanseri olan hastalarda inceliyor. Amaç güvenli en yüksek dozu bulmak, hücrelerin vücutta ne kadar kaldığını ve yan etkileri incelemek ve hücrelerin HER2 ifade eden meme kanseri hücreleriyle savaşıp savaşamadığını görmektir. Katılımcıların 18–80 yaş arasında olması, immünohistokimya (IHC) ile HER2 ifadesi 1+, 2+ veya 3+ olan metastatik ya da lokal nüks etmiş ameliyat edilemeyen meme kanseri tanısı bulunması ve hastalığın en az bir tedavi basamağından sonra ilerlemiş olması gerekmektedir.
