In brief

This is a hybrid type two study, with two simultaneous development phases. Phase A involves developing a public-private partnership to create the conditions for implementing CAR-T cell therapies in Colombia. Phase B will be a single-arm, non-randomized pilot clinical trial in patients over 18 years of age with recurrent/refractory (R/R) CD19+ hematopoietic lymphoid neoplasms, including R/R non-Hodgkin lymphoma (NHL), R/R B-cell acute lymphoblastic leukemia (B-ALL), and R/R mantle cell lymphoma; and R/R chronic lymphocytic leukemia (CLL) (including CLL with Richter transformation). This trial aims to determine the safety of administering autologous anti-C19 cells (ARI-0001) and the feasibility of local CAR-T cell production. Phase A of implementation aims to gather information on the domains of the multilevel model, including organizational context, suppliers, infrastructure, and institutional capacities, to identify barriers and facilitators in the implementation of CAR-T cell therapy in Colombia. National consensus will also be developed in the scientific, clinical, administrative, and regulatory spheres. Phase B will involve a pilot clinical trial in patients with relapsed/refractory CD19-positive hematopoietic lymphoid neoplasms. The production of ARI-0001 cells consists of the genetic modification of autologous T cells through lentiviral transduction of a chimeric antigen receptor (CAR) targeting the CD19 surface antigen. The process is carried out in the CliniMACS Prodigy® closed transduction system, which for this study will be located at and operated by staff from the District Institute of Science, Biotechnology, and Innovation in Health (IDCBIS). This pilot clinical trial will use an open-label, single-arm, staggered enrollment design with a safety observation period. The patient will receive the cell product infusion following administration of a lymphodepletion regimen at the National Cancer Institute (NCI). The patient will remain hospitalized for 14 days after the CAR-T cell infusion ARI-001 for medical monitoring, with subsequent outpatient follow-up until 12 months post-infusion. Subsequently, the patient will be offered a new informed consent process to participate in outpatient follow-up for up to 15 years.

Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Participants (Men and Women) ≥ 18 and ≥ 80 years of age.
• Participants capable of understanding and voluntarily signing the informed consent forms (prescreening and study forms) prior to any study-related evaluation or procedure, and able to adhere to the study visit schedule and other protocol requirements.
• CD19+ hematologic malignancy with a histologically documented diagnosis.
• Inclusion criteria according to the type of CD19+ hematologic malignancy measurable by the 2014 Lugano criteria (NHL) or IWCLL criteria (CLL) or EWALL criteria (ALL).
• B-cell precursor acute lymphoblastic leukemia (B-ALL relapsed/refractory (R/R)): Second-line or later relapse (including patients with prior blinatumumab use), second-line or later non-candidate for allogeneic transplantation, or relapse post-allogeneic transplantation.
• For patient inclusion, the disease must have progressed after the last regimen or the patient must not have achieved partial or complete remission with the last regimen, defined by the presence of at least 5% blasts in bone marrow or peripheral blood in an evaluation confirmed by flow cytometry or immunohistochemistry at least 2 weeks prior to recruitment (prescreening visit).
• The consideration of non-candidacy for allogeneic transplantation will be based on functional status, comorbidities, and persistence. Minimal Residual Disease (MRD) or lack of a donor.
• Relapsed/refractory diffuse large B-cell lymphoma (DLBCL) and high-grade lymphoma (R/R): Refractory to first-line treatment or relapsed within the first 12 months after completion of first-line chemoimmunotherapy, including an anti-CD20 monoclonal antibody, not a candidate for autologous transplantation; or refractory after two or more lines of systemic therapy; in second (or higher) relapse post-autologous transplantation; grade 3b follicular lymphoma or transformed to relapsed or refractory large B-cell lymphoma after at least one line of standard treatment.
• Symptomatic relapsed/refractory follicular lymphoma (FL): In third-line therapy (after at least two treatment regimens), including anti-CD20 therapy, and with a progression-free interval of less than two years; or in Relapse after autologous or allogeneic transplantation.
• Relapsed/refractory (R/R) mantle cell lymphoma, including Bruton's tyrosine kinase inhibitor (BTKi) therapy: In first (or higher) relapse, not a candidate for autologous or allogeneic transplantation; or in second (or higher) relapse following autologous or allogeneic transplantation.
• Symptomatic chronic lymphocytic leukemia (CLL): Relapse after two treatment regimens (including BTKi and BCL2 inhibitor in combination with anti-CD20) and with a progression-free interval of less than two years (POD24); or transformation to Richter syndrome, see inclusion criteria for DLBCL.
• Eastern Cooperative Oncology Group (ECOG) functional status ≤ 2.
• Life expectancy > 6 months, as determined by the Principal Investigator.
• Adequate organ function, defined as the following parameters at visit 2 Selection criteria:

• Platelet count ≥ 50,000/mm3
• Hemoglobin ≥ 10 g/dL
• Total bilirubin ≤ 1.5 x the institutional upper limit of normal (ULN).
• AST (SGOT)/ALT (SGPT) ≤ 3 x the institutional ULN
• Serum creatinine ≤ 2 x the institutional ULN or eGFR > 30 mL/min/1.73 m2

• Negative pregnancy test 14 days before trial enrollment and subsequently every month for the duration of the trial, or evidence of postmenopausal status or surgical sterilization.

You may not qualify if…

• The presence of any of the following will exclude the subject from trial enrollment:
• Failure to comply with the washout periods.
• Autologous or allogeneic stem cell transplantation or CAR-T cell therapy within 6 weeks prior to CAR-T cell infusion.

• History of autoimmune disease (e.g., rheumatoid arthritis, systemic lupus erythematosus) requiring immunosuppressive medication within the past 6 months.
• Pregnant or breastfeeding women are excluded from this trial because CAR-T cell therapy may be associated with teratogenic or abortifacient effects. Women of childbearing potential must have a negative serum pregnancy test. Due to the unknown, but potential, risk of adverse events in infants from maternal CAR-T cell therapy, breastfeeding should be discontinued. These potential risks may also apply to other agents used in this trial.
