What is the purpose of this trial?

This trial tests a new treatment, CD19-CD34t metabolically programmed CAR T-cell therapy, for individuals with certain types of non-Hodgkin's lymphoma or chronic lymphocytic leukemia that have returned or resisted standard treatments. The goal is to determine if this therapy can help when other treatments have failed. Participants will receive varying doses to identify the most effective one. Suitable candidates for this trial have these specific cancers and have undergone at least one previous treatment that was ineffective or ceased to work. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, guidelines about stopping lymphoma-directed therapy before certain procedures are mentioned, so it's best to discuss your specific medications with the trial team.

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

Research shows that a new treatment, CD19-CD34t CAR T-cell therapy, is under study to assess its safety for people. Patients who received similar treatments in the past have generally tolerated them well. However, some experienced side effects such as fever, tiredness, and low blood cell counts. These side effects often occur because the treatment activates the immune system to fight cancer.

Currently, this treatment remains in the testing phase, with scientists closely monitoring for any negative effects. It's important to note that the FDA has not yet approved this therapy, so researchers continue to gather safety information. For those considering joining a trial, these findings can provide insight into safety expectations, but discussing with a healthcare provider is also crucial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about CD19-CD34t metabolically programmed CAR T-cell therapy because it offers a novel approach to treating Non-Hodgkin's Lymphoma and Chronic B-Cell Leukemia. Unlike standard treatments like chemotherapy and monoclonal antibodies, this therapy uses genetically engineered T-cells that are programmed to specifically target and attack cancer cells expressing the CD19 protein. This method not only aims for more precise cancer cell elimination but also has the potential to reduce collateral damage to healthy cells, potentially leading to fewer side effects and improved outcomes. Additionally, the metabolic programming of these CAR T-cells could enhance their longevity and effectiveness within the body, offering new hope for patients with these conditions.

What evidence suggests that this treatment might be an effective treatment for non-Hodgkin's lymphoma and chronic B-cell leukemia?

Research shows that CD19-targeted CAR T-cell therapy has revolutionized the treatment of certain blood cancers, such as non-Hodgkin's lymphoma and chronic lymphocytic leukemia. This treatment modifies a patient's immune cells to attack cancer cells. Studies have found that these therapies can benefit patients whose cancer did not respond to other treatments. In this trial, participants will receive varying doses of a new version of these therapies, called metabolically programmed CAR T-cells. Early results suggest this version might work more effectively and last longer. Although more research is needed, this approach appears promising for treating challenging blood cancers. ^{1 4 6 7 8}

The CD22/CD19 dual-targeting CAR-T-cell therapy showed a remarkable overall response rate of 97% and a complete remission rate of 93% in patients with relapsed/refractory acute lymphoblastic leukemia (ALL), based on a meta-analysis of 14 studies involving 405 patients.

For non-Hodgkin lymphoma (NHL), the therapy resulted in an overall response rate of 85% and a complete remission rate of 57%, with manageable side effects such as cytokine release syndrome occurring in 86% of patients, indicating both efficacy and tolerability of this treatment approach.

CAR-T cell therapy has shown great success in treating blood cancers but faces challenges such as high recurrence rates and limited effectiveness against solid tumors.

Recent strategies focus on enhancing the metabolism of CAR-T cells to improve their adaptability and effectiveness in fighting tumors, both in laboratory settings and in living organisms.

CD19-directed CAR T-cell therapy has shown promising results in treating relapsed/refractory B-cell non-Hodgkin lymphoma, with 30-40% of patients achieving durable responses in pivotal phase I/II trials, leading to FDA and EMA approvals for specific therapies.

Despite its effectiveness, the therapy is associated with significant toxicities, such as cytokine release syndrome and neurotoxicity, which can limit its use and present challenges in patient management during treatment.

A patient with relapsed and refractory B cell acute lymphoblastic leukemia (B-ALL) achieved over 14 months of minimal residual disease-negative remission after receiving CAR-T cell therapy targeting both CD19 and CD22.

This case suggests that dual-targeting CAR-T cell therapy may enhance the durability of remission in B-ALL patients, potentially addressing issues of antigen escape seen with single-target therapies.

CAR T cells engineered to target the CD19 antigen have shown significant promise in treating patients with relapsed and refractory B-cell cancers, leading to durable responses even in those who did not receive a stem cell transplant.

While the treatment is effective, it is associated with notable side effects, including cytokine release syndrome and neurological toxicity, which are linked to T cell activation and expansion.
