摘要: The present invention provides therapeutics for the treatment of CCR9-positive cancers such as T-cell acute lymphoblastic leukemia. In particular, the present invention provides a CCR9 targeting moiety. The present invention furthermore relates to a CCR9 targeting moiety comprising a further targeting moiety, preferably a CD1a targeting moiety.

摘要: Relapsed/refractory T-cell acute lymphoblastic leukemia (T-ALL) has a dismal outcome, and no effective targeted immunotherapies for T-ALL exist. CD1a is exclusively expressed in cortical T-ALLs, a major subset of T-ALL. The expression of CD1a is restricted to cortical thymocytes and neither CD34+ progenitors nor T-cells express CD1a during ontogeny, confining the risk of on-target/off-tumor toxicity. The present invention provides CD1a-targeting moieties comprising a CD1a-which may be placed into T cells. The resultant CARTs are suitable for the treatment of cortical T-ALLs.
