Clinical Trial

Disease: Non-Hodgkin Lymphoma, NHL, (NCT04030195)

Disease info:

Non-Hodgkin lymphoma (also known as non-Hodgkin’s lymphoma, NHL, or sometimes just lymphoma) is a cancer that starts in white blood cells called lymphocytes, which are part of the body’s immune system. NHL is a term that's used for many different types of lymphoma that all share some of the same characteristics. NHL usually starts in lymph nodes or other lymph tissue, but it can sometimes affect the skin. 

B-cell lymphoma refers to types of non-Hodgkin lymphoma that are characterized by abnormalities of the "B-cells" (a type of white blood cell that makes antibodies to help fight infection). The condition may grow and spread slowly with few symptoms (also known as indolent lymphoma) or may be very aggressive with severe symptoms.

Frequency:
Non-Hodgkin lymphoma (NHL) is one of the most common cancers in the United States, accounting for about 4% of all cancers. About 77,240 people (42,380 males and 34,860 females) will be diagnosed with NHL. This includes both adults and children.

Note:
PBCAR20A is an allogeneic 'off-the-shelf' CAR T therapy. Using T cells derived from healthy donors as starting material, then utilizes the ARCUS genome editing technology to modify the cells via a single-step engineering process. By inserting the CAR gene at the T cell receptor (TCR) locus, this process knocks in the CAR while knocking out the TCR, creating a cell product that is designed to prevent graft-versus-host disease.

Description

This is a multicenter, nonrandomized, open-label, parallel assignment, single-dose, dose-escalation, and dose-expansion study to evaluate the safety and tolerability, find an appropriate dose to optimize safety and efficacy, and evaluate clinical activity of PBCAR20A in subjects with relapsed/refractory (r/r) Non-Hodgkin Lymphoma (NHL) or r/r Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL). Before initiating PBCAR20A, subjects will be administered lymphodepletion chemotherapy composed of fludarabine and cyclophosphamide. At Day 0 of the Treatment Period, subjects will receive a single intravenous (IV) infusion of PBCAR20A. All subjects are monitored during the treatment period through Day 28. All subjects who receive a dose of PBCAR20A will be followed in a separate long-term follow-up (LTFU) study for 15 years after exiting this study.

Intervention:

  • Genetic: PBCAR20A

    Single dose of Allogeneic Anti-CD20 CAR T cells will be infused, and a classic "3+3" dose escalation will be applied.

    Other Name: Allogeneic Anti-CD20 CAR T cells

  • Drug: Fludarabine

    Fludarabine is used for lymphodepletion.

  • Drug: Cyclophosphamide

    Cyclophosphamide is used for lymphodepletion.
