- Subjects with history of a new pulmonary embolism (PE) /deep vein thrombosis (DVT) within 6 months of beginning lymphodepletion requiring ongoing anticoagulation.
- Subjects with second malignancies if the second malignancy has required therapy in the last 3 years or is not in complete remission; exceptions to this criterion include successfully treated non-metastatic basal cell or squamous cell skin carcinoma, or prostate cancer that does not require therapy other than hormonal therapy.
- Pregnant or lactating women. Pregnant women are excluded from this study because CAR-79b-19 T cell drug product is an agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with CAR-79b-19 T cell drug product, breastfeeding should be discontinued if the mother is treated with CAR-79b-19 T cell drug product.
- Additional Exclusion Criteria for Leukapheresis for Part B, Arm B.2:
- Prior CD19-directed cellular therapy.

About this study
Official title: A Phase I Study of Bivalent CD79b and CD19 Directed CAR T Cells in Patients With Relapsed/Refractory Non-Hodgkin Lymphoma
This research study involves the study of CD79b-19 CAR T cells for treating people with relapsed/refractory Non-Hodgkin Lymphoma and to understand the side effects when treated with CD79b-19 CAR T cells.
This research study involves the study drugs:
- CD79b-19 CAR T cells
- Fludarabine and Cyclophosphamide: Standardly used chemotherapy drugs as part of lymphodepleting process
Read the detailed description
This is a two-part, non-randomized, open label, single-site Phase 1 study of CD79b-19 CAR T cells as a treatment for relapsed/refractory Non-Hodgkin Lymphoma.
This study consists of 2 parts:
- Part A (Dose Escalation): The investigators are looking to find the highest dose of the study intervention that can be administered safely without severe or unmanageable side effects, not everyone who participates in this research study will receive the same dose of the study intervention. The dose given will depend on the number of participants who have been enrolled prior and how well the dose was tolerated. Once determined, this highest dose will then be used in the dose expansion part of the study.
- Part B (Expansion Cohort): Participants will be treated at the respective dose as determined during Part A (Dose Escalation).
CD79b-19 CAR T cells is an investigational treatment that uses a person's own immune cells, called T cells, to try to kill their cancerous cells. T cells fight infections and can also kill cancer cells in some cases. The U.S. Food and Drug Administration (FDA) has not approved CD79b-19 CAR T cells as a treatment for any disease. This is the first time that CD79b-19 CAR T cells will be given to humans.
The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.
Participants will receive one infusion of the study treatment and will be followed for up to 2 years.
It is expected that about 24 people will take part in this research study.

| Study group | Role | What they receive |
|---|---|---|
| CD79b-19 CAR T cells | Experimental | Prior to receiving CD79b-19 CAR T cells, participants will undergo two preparatory processes:
* Leukapheresis: During Week -3 white blood cells will be collected.
* Lymphodepletion: On days, -5 to -3 participants will receive 3 days of chemotherapy to decrease the number of lymphocytes
CD79b-19 CAR T cells will be administered intravenously on day 0 only. The dose you will receive will depend on the number of participants who have been enrolled prior and how well the dose was tolerated. The CD79b-19 CAR T cells will be administered over approximately 1 hour. Receives: Drug: CD79b-19 CAR T cells; Drug: Cyclophosphamide; Drug: Fludarabine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of adverse events (AEs)
Study-related adverse events (AEs) will be listed and tabulated by type and study cohort. The rate of AEs in all infused patients, both within study cohorts and overall, will be calculated and reported with exact 95% confidence intervals. A separate safety analysis will report similar information within patients infused at the target dose of 1x108 or 3x108 CD79b-19 CAR T cells.
Measured: From Day 0 to 2 years post-treatment
Incidence of Dose Limiting Toxicity (DLT)
Dose-limiting toxicities will be listed and tabulated by type and study cohort.
Measured: From Day 0 to 2 years post-treatment
Secondary outcomes (3)
Overall Response Rate (ORR)
Data will be listed, tabulated, and presented descriptively using Kaplan Meier plots.
Measured: 1 month, 6 months, 12 months, and 24 months after CD79b-19 CAR T cells treatment
Overall Survival (OS)
Data will be listed, tabulated, and presented descriptively using Kaplan Meier plots.
Measured: 1 month, 6 months, 12 months, and 24 months after CD79b-19 CAR T cells treatment
Progression Free Survival (PFS)
Data will be listed, tabulated, and presented descriptively using Kaplan Meier plots.
Measured: 1 month, 6 months, 12 months, and 24 months after CD79b-19 CAR T cells treatment
