Brief Summary

This is a Phase I/II interventional, open-label treatment study designed to evaluate the safety and efficacy of concomitant therapy with anti-CD19 CAR T-cells and Lenalidomide in adult patients with relapsed/refractory chronic lymphocytic leukemia (CLL) who have been pretreated with Ibrutinib for 3 months prior to leukapheresis.

Conditions

Chronic Lymphocytic Leukaemia (CLL); Small Lymphocytic Lymphoma (SLL)

Keywords

anti-CD19 CAR T-cells; Lenalidomide; Ibrutinib

Outcome Measures

Primary Outcomes (1)

• Adverse events incidence

  24 months

Study Arms (4)

Low dose antiCD19 CAR T-cells plus low dose Lenalidomide

EXPERIMENTAL

Phase 1: Determine safety of IL-7/IL-15 expanded 50x10\^6 antiCD19 CAR-T cells with concomitant low dose Lenalidomide in patients with relapsed/refractory CLL. Patients will be enrolled in 3+3 fashion. Phase 1b: Six to nine patient expansion cohorts. If six patients are enrolled in Phase 1 then only six additional patients will be added. If three patients are enrolled in Phase 1 then nine additional patients will be treated for a total of 12 patients.

Drug: Lenalidomide

Low dose antiCD19 CAR T-cell therapy plus high dose Lenalidomide

EXPERIMENTAL

Phase 1: Determine safety of IL-7/IL-15 expanded 50x10\^6 antiCD19 CAR-T cells with concomitant high dose Lenalidomide in patients with relapsed/refractory CLL. Patients will be enrolled in 3+3 fashion. Phase 1b: Six to nine patient expansion cohorts. If six patients are enrolled in Phase 1 then only six additional patients will be added. If three patients are enrolled in Phase 1 then nine additional patients will be treated for a total of 12.

Drug: Lenalidomide

High dose antiCD19 CAR T-cell therapy plus low dose Lenalidomide

EXPERIMENTAL

Phase 1: Determine safety of IL-7/IL-15 expanded 150x10\^6 antiCD19 CAR-T cells with concomitant low dose Lenalidomide in patients with relapsed/refractory CLL. Patients will be enrolled in 3+3 fashion. Phase 1b: Six to nine patient expansion cohorts. If six patients are enrolled in Phase 1 then only six additional patients will be added. If three patients are enrolled in Phase 1 then nine additional patients will be treated for a total of 12.

Drug: Lenalidomide

High dose antiCD19 CAR T-cell therapy plus high dose Lenalidomide

EXPERIMENTAL

Phase 1: Determine safety of IL-7/IL-15 expanded 150x10\^6 antiCD19 CAR-T cells with concomitant high dose Lenalidomide in patients with relapsed/refractory CLL. Patients will be enrolled in 3+3 fashion. Phase 1b: Six to nine patient expansion cohorts. If six patients are enrolled in Phase 1 then only six additional patients will be added. If three patients are enrolled in Phase 1 then nine additional patients will be treated for a total of 12.

Drug: Lenalidomide

Interventions

Dose Level 1

Also known as: Revlimid

High dose antiCD19 CAR T-cell therapy plus low dose Lenalidomide; Low dose antiCD19 CAR T-cells plus low dose Lenalidomide
