Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

What data supports the effectiveness of the treatment CLBR001 CAR-T for Non-Hodgkin's Lymphoma?

Research shows that similar CAR-T cell therapies targeting CD20 have been effective in treating B-cell non-Hodgkin lymphoma, with a high response rate and some patients achieving complete remission. This suggests that CLBR001 CAR-T, which is also a CAR-T cell therapy, may have potential effectiveness for this condition. ^{1 2 3 4 5}

Is CLBR001 CAR-T therapy safe for humans?

CAR-T therapies, including those targeting CD19 like CLBR001, have shown some common side effects such as cytokine release syndrome (a reaction causing fever and low blood pressure) and neurologic toxicities (affecting the nervous system), but these are usually treatable and reversible. Studies have shown that these therapies are generally safe, with most side effects being manageable. ^{6 7 8 9 10}

How is the CLBR001 CAR-T treatment different from other treatments for non-Hodgkin's lymphoma?

CLBR001 CAR-T treatment is a type of immunotherapy that uses specially modified T cells to target and destroy cancer cells, offering a novel approach for patients with non-Hodgkin's lymphoma who have not responded to standard treatments. Unlike traditional chemotherapy, CAR-T therapy is personalized and involves reprogramming a patient's own immune cells to fight the cancer. ^{6 9 10 11 12}

What is the purpose of this trial?

This trial involves monitoring patients who received a special cancer treatment using their own modified immune cells. These patients are followed for an extended period to check for safety and effectiveness. The treatment works by reprogramming the patient's immune cells to better fight cancer and has shown promising results.

Findings from Research

In a phase IIa trial involving 11 patients with relapsed or refractory CD20+ B-cell lymphoma, the use of CAR-modified T cells (CART-20) resulted in an impressive overall response rate of 81.8%, with 6 complete remissions and 3 partial remissions, indicating strong efficacy.

The treatment was well-tolerated with no severe toxicity reported, and the median progression-free survival was over 6 months, suggesting that CART-20 is a promising option for patients with difficult-to-treat lymphomas.

CAR-T therapy is an innovative treatment that modifies T cells to target and attack cancer cells, such as those found in large B cell lymphoma.

In this case, a patient treated with CAR-T therapy for lymphoma developed myocarditis, highlighting a potential safety concern associated with this treatment approach.

A 61-year-old male patient with intravascular large B-cell lymphoma and CNS involvement achieved complete remission after receiving CAR T-cell therapy following a conditioning regimen and autologous stem cell transplantation.

The treatment was associated with only mild side effects, specifically grade 1 cytokine release syndrome, and no serious adverse events like neurotoxicity or pseudoprogression, suggesting that CAR T-cell therapy can be safely administered to patients with CNS involvement.

Anti-CD19 CAR T-cell therapy has demonstrated significant clinical activity in treating B-cell non-Hodgkin lymphoma (NHL), with objective response rates ranging from 50-83% for relapsed diffuse large B-cell lymphoma (DLBCL), 83-93% for follicular lymphoma (FL), and 93% for mantle cell lymphoma (MCL).

This therapy represents a promising treatment option for patients with poor-risk refractory B-cell NHLs, highlighting its potential efficacy in difficult-to-treat cases.

CAR-T cell therapy demonstrated a high overall response rate of 85.2% in 27 patients with relapsed/refractory B cell non-Hodgkin lymphoma, with a complete response rate of 63.0% after a median follow-up of 32 months.

While adverse reactions like cytokine release syndrome and myelosuppression were common, they were manageable, and patients achieving a complete response had significantly better long-term survival rates compared to those who did not.

Chimeric antigen receptor T-cell (CAR-T) therapy has shown promising efficacy in treating relapsed or refractory diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL), with complete response rates of 40-60% in pivotal trials, and some patients achieving long-term remission.

While CAR-T therapy can lead to significant toxicities such as cytokine release syndrome and neurologic issues, these are generally treatable and reversible, making CAR-T a viable option for patients with poor prognosis in these lymphoma subtypes.

In a phase I study involving 10 patients with refractory diffuse large B-cell lymphoma (DLBCL), the anti-CD19 CAR T cell therapy (C-CAR011) demonstrated a 50% overall response rate at 12 weeks, indicating promising efficacy for this treatment.

The therapy showed a favorable safety profile, with 90% of patients experiencing cytokine release syndrome but no severe (grade ⩾ 3) cases or neurotoxicity, suggesting it is a safe option for patients with heavily treated DLBCL.

Adoptive cellular therapy using CAR-modified T cells targeting CD19 has shown significant clinical efficacy in treating relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL) in both children and adults, with some patients also benefiting from treatment for chronic lymphocytic leukemia (CLL) and B-cell non-Hodgkin lymphoma (B-NHL).

Current research is expanding the use of CAR T-cell therapies to other cancers, including multiple myeloma and solid tumors, while also addressing challenges such as severe cytokine release syndrome and neurologic toxicities associated with the treatment.

Adoptive therapy using CAR T-cells, specifically targeting CD19, represents a promising new treatment option for patients with high-risk B-cell non-Hodgkin's lymphomas, such as DLBCL and FL, who do not respond to standard therapies.

The review highlights the efficacy and toxicity profiles of CD19-directed CAR T-cell therapy, showing its potential as a viable alternative for patients with poor prognosis, supported by data from both early single-center studies and larger multicenter clinical trials.

In a study of 129 adults with relapsed/refractory diffuse large B cell lymphoma (DLBCL) treated with CD19-directed CAR T therapy, 95.4% were hospitalized during treatment, with a median hospital stay of 17 days, highlighting the intensive care required during this therapy.

The estimated 6-month risk of requiring subsequent treatment after CAR T was 36.2%, indicating a significant chance of treatment failure, and emphasizing the need for effective salvage therapies for DLBCL patients.
