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 and again within 48 hours of initiation of lymphodepleting chemotherapy.

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.

5. Study Description

Brief Summary
This is a phase 1/1b, interventional single arm, open label, treatment study designed to evaluate the safety and feasibility of infusion of autologous T cells engineered to contain an anti-cluster of differentiation 19 (CD19) and anti-cluster of differentiation 20 (CD20) single chain variable fragment (scFv) coupled to cluster of differentiation CD3ζ (CD3ζ) and co-stimulatory domain 4-1BB (4-1BB) signaling domains in patients with relapsed and/or refractory CD19 or CD20 positive B cell malignancies
Detailed Description
This is a single center, single arm, open label phase I/1b study to demonstrate the feasibility of manufacturing CAR-T cells expressing tandem receptors against both CD20 and CD19 (CAR-20/19-T) in a completely closed system using the CliniMACS Prodigy device and then determine the safety of this dual targeted CAR in a first-in-human study of patients with relapsed and refractory B cell malignancies. Secondary outcomes will include response rates, and observed toxicities of the treatment, specifically the development of cytokine release syndrome (CRS), an inflammatory storm that has been seen with previous CAR-T therapies.

Sequential Assignment
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).
