Targeting a Specific Glycosylated Epitope of CD43 with a New Humanized Monoclonal Antibody for the Treatment of Pediatric and Adult T-Cell Acute Lymp…
2018
Abstract Introduction: T-cell acute lymphoblastic leukemia (T-ALL) accounts for about 20% of pediatric and adult ALL cases. Despite the use of intensive chemotherapy protocols, 25% of children and 50% of adult patients fail to respond or relapse. The 3-years prognosis for these patients is poor and novel treatment options are needed. The targeting of tumor-associated antigens by monoclonal antibodies (mAb) is among the most investigated immune-therapeutic strategies. Accordingly, we developed a new humanized mAb (hUMG1), directed against a heavy glycosylated epitope of CD43 which presents a high reactivity against T-ALL cells. Here we investigated the pre-clinical therapeutic activity and t…
Therapeutic afucosylated monoclonal antibody and bispecific T-cell engagers for T-cell acute lymphoblastic leukemia
2021
BackgroundT-cell acute lymphoblastic leukemia (T-ALL) is an aggressive disease with a poor cure rate for relapsed/resistant patients. Due to the lack of T-cell restricted targetable antigens, effective immune-therapeutics are not presently available and the treatment of chemo-refractory T-ALL is still an unmet clinical need. To develop novel immune-therapy for T-ALL, we generated an afucosylated monoclonal antibody (mAb) (ahuUMG1) and two different bispecific T-cell engagers (BTCEs) against UMG1, a unique CD43-epitope highly and selectively expressed by T-ALL cells from pediatric and adult patients.MethodsUMG1 expression was assessed by immunohistochemistry (IHC) on a wide panel of normal t…
