|Condition or disease||Intervention/treatment||Phase|
|CLL/SLL Lymphomas Non-Hodgkin's B-Cell||Biological: CAR-20/19-T||Phase 1|
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||24 participants|
|Intervention Model:||Sequential Assignment|
|Intervention Model Description:||
The study is divided into two phases. Phase 1 and Phase 1b. Phase 1: consists of 2 cohorts; dose escalation and dose expansion. The CAR-T cells were given over 2 days.
In the phase 1 portion, there will be a dose escalation cohort to determine the safe CAR-20/19-T cell dose in patients with CLL/SLL and NHL. Once the desired dose has been identified there will be a 6 patient dose expansion phase at the specified dose level.
Phase 1b: In the Phase 1b portion of the study, we will test the safety of unfractionated CAR-T cells utilizing the safe dose identified in the phase 1 portion (2.5 x 10^6 cells/kg).

|Official Title:||Phase 1/1b Study of Redirected Autologous T Cells Engineered to Contain an Anti CD19 and Anti CD20 scFv Coupled to CD3ζ and 4-1BB Signaling Domains in Patients With Relapsed and/or Refractory CD19 or CD20 Positive B Cell Malignancies|
|Actual Study Start Date :||October 16, 2017|
|Actual Primary Completion Date :||October 1, 2019|
|Estimated Study Completion Date :||October 1, 2022|
Experimental: CAR-20/19-T cells
Dose Escalation Phase: CAR-20/19-T transduced with a lentiviral vector to express an anti CD19 and anti CD20 tandem receptor coupled to CD3ζ and 4-1BB signaling domains will be administered by IV injection. Patients will receive one of four dose levels based the study protocol. Cells will be given over 2 days, 30% of cells infused on Day 0 and 70% of cells infused on Day 1 in the Phase 1 portion and as a single infusion in the Phase 1b portion
CAR-20/19-T cells will be administered either fresh or thawed after cryopreservation by IV injection.
Dose Level -1: 1 x 10^5 CAR-20/19-T cells/kg
Dose Level 0: 2.5 x10^5 CAR-20/19-T cells/kg (starting dose level)
Dose Level 1: 7.5 x10^5 CAR-20/19-T cells/kg
Dose Level 2: 2.5 x10^6 CAR-20/19-T cells/kg (goal cell dose)
Expansion Dose Level: 2.5 x 10^6 cells/kg (single infusion)
- Number of Adverse Events after CAR 20/19-T cell infusion [ Time Frame: Within the first 28 days after infusion ]Determine the toxicity profile of CAR 20/19-T cell therapy
