Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy, Safety

To evaluate the efficacy (response rate) of ARI-0001 cells in paediatric patients with CD19+ acute lymphoblastic leukaemia that is resistant or refractory to therapy.

Secondary objectives 4

  1. To evaluate safety and tolerability of ARI-0001 therapy
  2. To further evaluate efficacy by evaluating duration of response and survival (event-free, relapse-free and overall survival) after ARI-0001 cell infusion
  3. To evaluate the kinetics of ARI-0001 cells in peripheral blood, bone marrow and cerebrospinal fluid after its administration
  4. To evaluate functional CART-cell persistence by evaluating B-cell aplasia in peripheral blood

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 8

  1. Age 0 to 18 years
  2. Diagnosis of relapsed /refractory CD19+ ALL defined as at least one of the following criteria: • First relapse if high-risk features. Definition of high risk 1st relapse will include at least one of the following: o any relapse before 6 months after completion of chemotherapy o high risk cytogenetics: t(4;11)(q21; q23) /AF4:: KMT2A or t (1;19) (q23; p13) / TCF3/PBX or t(17;19) (q22;p13)/ TCF3::HLF or hypodiploid (<44 chromosomes) or TP53 mutation and/ or TP53 deletion
  3. Disease burden defined as: • Morphologic relapse in bone marrow (≥5% blasts) or presence of leukemic blasts in an extramedullary site • MRD positivity (≥0.01%) by flow cytometry or PCR
  4. Subjects with the following features are NOT excluded: • Isolated extramedullary involvement • Down syndrome patients • CNS3 involvement if disease is stable and a thorough evaluation of risk/benefit assessment has been stablished by the principal investigator and the treating physician • Ph+ (BCR::ABL1) ALL if they are intolerant or have failed at least 1 TKI • Prior blinatumomab therapy provided blasts remain CD19+ >90% blasts at inclusion
  5. Performance status: Lansky (age <16 years) or Karnofsky (age ≥16 years) ≥ 50%
  6. Life expectancy >3 months
  7. Adequate venous access and no contraindications for lymphoapheresis
  8. Signature of informed consent (patient and/or legal guardian)

Exclusion criteria 11

  1. Any other concomitant neoplasia, unless it has been in complete remission for 3 years or longer
  2. Active immunosuppressive therapy with the exception of hydrocortisone 12 mg/m2/day (or equivalent);
  3. Active acute or chronic graft versus host disease (GVHD) >grade 1
  4. Prior therapies: • CAR-T cell therapy • Donor lymphocytes infusion <28 days before enrollment • Immunosuppressive therapy (cyclosporine, mophetil mycophenolate and others) must be stopped <14 days before enrollment • Alentuzumab, thymoglobulin (ATG) < 3 months before enrollment
  5. Active infection that is uncontrolled or requiring systemic intravenous medical therapy;
  6. Any experimental or non-commercialized therapy in the previous 4 weeks
  7. Active HIV, HBV or HCV infection
  8. Any concomitant and uncontrolled medical or psychiatric disease that, under investigator consideration, would prevent the subject from participating in the study
  9. Severe organic impairment defined by cardiac ejection fraction <50%, pulmonary reserve defined as > Grade 1 dyspnea and pulse oxygenation <91% on room air, creatinine >1.5 times greater than the upper limit of normality (ULN) for sex and age or conjugated bilirubin >2 x ULN
  10. Lactating or pregnant women
  11. Men or women of childbearing potential unable or unwilling to use highly efficient contraceptive measures during the study

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Complete response rate (complete remission [CR] rate plus CR rate with incomplete haematological recovery [CRi]), with undetectable measurable residual disease by multiparameter flow cytometry within day +100 after the infusion of ARI-0001 cells. In patients with isolated extramedullary disease, response evaluation will be done through morphology and flow cytometry of the cerebrospinal fluid (CSF) and/or imaging tests (PET-CT or MRI)

Secondary endpoints 8

  1. Key secondary endpoint: Event-free survival (EFS) at month 12
  2. Duration of remission: defined as the time from achievement of CR or CRi (whichever occurs first) to relapse or death due to ALL
  3. Relapse free survival (RFS) at 12 months
  4. Overall survival at 12 months
  5. Transplant and disease-free survival at 6 and 12 months
  6. In vivo survival of ARI-0001 cells in peripheral blood as determined by flow cytometry and by qPCR of the transgene weekly the first month, monthly in the first 6 months and then at 12 months.
  7. B-cell aplasia, measured by flow cytometry, weekly the first month, monthly in the first 6 months, every 3 months from month 6 to month 12 and every 6 months until end of study
  8. Toxicity, defined as adverse events of grade ≥3 according to common toxicity criteria (version 5.0). Adverse events of significant interest will be CRS, ICANS and cerebral ooedema, which will be graded according to the ASTCT classification (1). Procedure-related mortality will also be measured.
