Brief Summary:
In this phase I study, the investigators will first evaluate the safety of CAR20.19.22 T-cells in patients with B-cell non-Hodgkin lymphoma (NHL) / chronic lymphocytic leukemia (CLL).

Condition or disease Intervention/treatment Phase
B-cell Non Hodgkin Lymphoma B-cell Chronic Lymphocytic Leukemia Biological: Dose Level -1: 0.75x10^6 cells/kg CAR20.19.22 cells Biological: Dose Level 0: 1x10^6 cells/kg CAR20.19.22 cells Biological: Dose Level 1: 2.5x10^6 cells/kg CAR20.19.22 cells Biological: Dose expansion: The maximum tolerated dose of CAR20.19.22 cells Phase 1

Detailed Description:

This is a phase I, interventional, open label, dose-finding treatment study designed to evaluate the safety and efficacy CAR20.19.22 T-cells in adult patients with B-cell malignancies that have failed prior therapies.

After the maximal tolerated dose (MTD) is determined, an additional dose-expansion cohort of up to 12 patients may be enrolled at that dose to further describe the safety and preliminary efficacy of that dose.

Special Criteria for regarding Fertility and Contraception:

Female subjects of reproductive potential (women who have reached menarche or women who have not been post-menopausal for at least 24 consecutive months, i.e., who have had menses within the preceding 24 months, or have not undergone a sterilization procedure [hysterectomy or bilateral oophorectomy]) must have a negative serum or urine pregnancy test performed as part of eligibility criteria. Lactating women are eligible for this study but will be asked to not provide breast milk to their child from Day -4 through Day +90 after CAR T-cell therapy. It is possible they may no longer be able to lactate after receiving chemotherapy and treatment.

Due to the high-risk level of this study, while enrolled, all subjects must agree not to participate in a conception process (e.g., active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization). Additionally, if participating in sexual activity that could lead to pregnancy, the study subject must agree to use reliable and double barrier methods of contraception during the follow-up period of the protocol.

Acceptable birth control includes a combination of two of the following methods:

  • Condoms (male or female) with or without a spermicidal agent.
  • Diaphragm or cervical cap with spermicide.
  • Intrauterine device (IUD).
  • Hormonal-based contraception.

Subjects who are not of reproductive potential (women who are premenarche or have been post-menopausal for at least 24 consecutive months or have undergone hysterectomy tubal ligation, salpingectomy, and/or bilateral oophorectomy or men who have documented azoospermia) are eligible without requiring the use of contraception.
