About this trial

The 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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

All eligible participants must have documentation of CD19 tumour expression demonstrated in tissue biopsy, bone marrow or peripheral blood within the 3 months prior to study screening.

Adequate organ function

Participant age: 18 to 75 years.

Provide written informed consent

Disqualifiers

Isolated extra-medullary disease.

Participants with concomitant genetic syndrome, such as Fanconi anemia, Kostmann syndrome, Shwachman syndrome or any other known familial bone marrow failure syndrome.

Prior malignancy, except carcinoma in situ of the skin or cervix treated with curative intent and with no evidence of active disease.

Prior treatment with any gene therapy product.
