T-ALL/Lymphoma Clinical Trial
CD7 CAR-T Cell Treatment of Relapsed/Refractory CD7+ T -Acute Lymphoblastic Leukemia/ Lymphoma
This is a phase I, interventional, single arm, open label, treatment study to evaluate the safety and tolerability of CD7 CAR-T cells in patients with relapsed and/or refractory, high risk hematologic malignancies.
T-acute lymphoblast leukemia (T-ALL) accounts for 15-20% of all ALL cases. It is a neoplastic lymphoid leukemia characterized by the proliferation of immature precursor T cells. T-ALL is a highly aggressive tumor. Adults need intensive chemotherapy, and the cure rate is <50%, even with stem cell transplantation. The prognosis is also very poor. The combined chemotherapy has significantly improved the prognosis of T-acute lymphoblast leukemia/lymphoma. However, once the disease appears to be relapsed/refractory, there is limited treatment options, and the overall prognosis is extremely poor. Therefore, exploring safe and effective treatments is a critical unmet medical need. Since 95% of T-ALLs express CD7, this might provide an effective targeting approach for the vast majority of T-ALL cases. ;
