What is the purpose of this trial?

This trial aims to test a new T-cell therapy called EB103 for individuals with non-Hodgkin's lymphoma that hasn't responded to other treatments. Researchers seek to determine the safety and effectiveness of EB103 at different doses. The trial is open to those who have experienced a return or worsening of their lymphoma after at least two types of treatments or whose disease returned within 12 months after a stem cell transplant. This study might suit individuals whose lymphoma hasn’t improved with typical treatments and who have a confirmed diagnosis of B-cell non-Hodgkin's lymphoma.

As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding how EB103 works in people.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you are on certain treatments like systemic immunosuppressants or have had a recent live vaccine, you may need to discuss this with the trial team.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research shows that EB103, a T-cell therapy for treating B-cell Non-Hodgkin's Lymphoma, is currently being tested for patient safety. The treatment is in early testing stages, focusing on safety and patient tolerance. Although it has shown promise in lab tests, scientists are now closely observing patient responses.

In similar T-cell therapies, common side effects include fever and tiredness. More serious effects can occur but are less common and are under close observation. Prospective trial participants should know that ensuring treatment safety is the primary focus. Researchers are carefully monitoring participants for any issues. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for Non-Hodgkin's Lymphoma, which often involve chemotherapy and radiation, EB103 is a T-cell therapy that harnesses the body's immune system to fight cancer. Researchers are excited about EB103 because it specifically targets the cancer cells with engineered T-cells, potentially offering a more precise and personalized treatment. This approach not only aims to improve effectiveness but also reduce the side effects typically associated with traditional therapies.

What evidence suggests that this T-cell therapy could be effective for Non-Hodgkin's Lymphoma?

Research shows that EB103 T-cell therapy, studied in this trial, has promising results for treating relapsed/refractory B-cell Non-Hodgkin's Lymphoma. In an earlier study, all patients in the second dose group had no detectable cancer after one month. Early data also suggest that EB103 is safe, with no serious side effects related to the treatment. The therapy modifies a person's own T cells to better find and attack cancer cells. This approach aims to offer new hope to patients whose cancer has returned or hasn't responded to other treatments. ^{3 4 5 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• EB103

Trial Overview The trial is testing EB103, a new T-cell therapy for those whose lymphoma has returned or didn't respond to treatment. It starts by finding the best dose and then checks how well it works in more people at that dose.

How Is the Trial Designed?

Group I: EB103 Experimental Treatment 1 Intervention

Approximately six (6) subjects will be treated to determine the RP2D. At the designated RP2D, approximately fifteen (15) additional subjects will be treated.

Published Research Related to This Trial

CAR T-cell therapy has shown promising results in early clinical trials for classic Hodgkin lymphoma (cHL), particularly with Epstein-Barr virus-specific T cells and CD30 CAR T cells, indicating potential for effective treatment options.

Research is ongoing into targeting the immunosuppressive tumor microenvironment in cHL using CD19 and CD123 CAR T cells, highlighting innovative strategies to enhance the efficacy of adoptive immunotherapy for this type of lymphoma.

CAR T cell therapy, which modifies T cells to target the CD19 antigen on B cells, has shown significant clinical effectiveness in treating various B cell malignancies, including chronic lymphocytic leukemia and acute lymphoblastic leukemia, with some patients experiencing long-term remissions.

The FDA has recognized the potential of CD19-directed CAR T cells by granting 'breakthrough' designation for their use in treating relapsed or refractory acute lymphoblastic leukemia in both adults and children.

CD19-directed CAR T-cell therapy has significantly transformed the treatment approach for aggressive B-cell non-Hodgkin lymphoma, offering new hope for patients.

There are currently three commercially available CAR T-cell therapies targeting CD19, indicating a growing acceptance and application of this innovative immunotherapy in clinical practice.

In a phase 1 clinical trial involving 14 patients with relapsed/refractory acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL), the novel Sleeping Beauty (SB) CD19-specific CAR T-cell therapy demonstrated a strong safety profile, with no serious adverse events directly linked to the treatment and only mild cytokine release syndrome observed.

Efficacy results showed that 38% of patients with ALL achieved complete remission or incomplete count recovery, and 50% of patients with diffuse large B-cell lymphoma (DLBCL) also achieved complete remission, indicating promising antitumor activity of the SB-based CAR constructs.

CD19CAR T cells have shown promising results in treating aggressive B-lineage cancers, but their effectiveness can be limited by the loss of the targeted CD19 antigen, leading to treatment failure.

The newly developed adapter CAR T cell technology (AdCAR) allows for multitargeting of different antigens, such as CD20 and CD22, which can enhance the anti-cancer activity and potentially overcome issues related to antigen loss in lymphoma treatments.

A case study highlights a rare but severe instance of neurotoxicity occurring 9 months after treatment with CD19-directed CAR T cells in a patient with relapsed large B-cell lymphoma, despite prior successful treatment and immunosuppression.

The presence of high CAR T-cell DNA levels and elevated inflammatory markers in the cerebrospinal fluid suggests that CAR T cells may infiltrate the brain and contribute to delayed neurotoxic effects, emphasizing the need for ongoing monitoring of neurological side effects in patients.
