LentiGlobin BB305
外观
LentiGlobin BB305是一種治療β-地中海貧血的實驗性療法,β-地中海貧血是一種罕見但可能會使人衰弱的血液疾病。這項療法由Bluebird Bio開發,並在2015年2月獲美国食品药品监督管理局指定為「突破性療法」[1]。在早期的臨床試驗中,數位需要長期輸血治療的患者在此療法後能夠更長時間不用輸血[2][3][4]。
作用機轉
[编辑]β-地中海貧血是HBB基因突變或缺失造成,血红蛋白的β鏈合成減少或缺乏,最終導致由嚴重貧血到無症狀等程度不等的結果[5]。LentiGlobin BB305是一種病毒載體,能在生物體外將具功能的HBB基因插入患者的造血干细胞(HSC),之後再將經基因工程改造的造血幹細胞植回患者體內[6][7]。
