Is NCT03765177 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies CLIC-1901 for acute lymphoblastic leukemia.

Phase 1/2RecruitingOttawa Hospital Research InstituteNCT03765177Data as of May 2026

Treatment: CLIC-1901The investigators propose an early phase study defined as a phase I/II trial assessing safety, feasibility and efficacy of CLIC-1901 autologous anti-CD19 Chimeric Antigen Receptor T cells (CAR-T) cells for participants with relapsed/refractory CD19 positive (CD19+) Acute Lymphoblastic Leukemia (ALL) and non-Hodgkin's Lymphoma (NHL). The Initial Stage of the study (n=20 participants) will focus on feasibility and safety while the Extended Stage will include all participants enrolled in the study (n=additional 80 participants for a total of 100) and will focus on efficacy and safety outcomes. In the proposed trial, we will administer our CAR-T cell product to these participants as a single infusion. Participants will undergo (a) lymphodepletion with cyclophosphamide and fludarabine, followed by (b) infusion of autologous CLIC-1901 CAR-T cells. All treatments will be delivered intravenously.
