What is the purpose of this trial?

This trial tests a new treatment called DuoCAR20.19.22-D95 for individuals with certain aggressive blood cancers, such as Non-Hodgkin's Lymphoma and B-cell Acute Lymphoblastic Leukemia. The trial aims to determine the treatment's safety and identify the highest dose patients can tolerate. The treatment uses modified T cells (a type of immune cell) to target and fight cancer cells after chemotherapy. Suitable candidates for this trial have experienced a recurrence of these specific cancers or have not responded to previous treatments. 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 requires stopping certain medications before participation. Steroids must be stopped more than 72 hours before certain procedures, and other immunosuppressive medications must be stopped at least 2 weeks prior. Additionally, some cancer treatments and antibodies have specific stop times before the trial.

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

Research has shown that DuoCAR20.19.22-D95 has not raised any safety concerns in early trials. This treatment uses specially altered T cells to target specific proteins on cancer cells. Studies suggest it may be safe and manageable for patients with certain B-cell cancers, such as non-Hodgkin's lymphoma. Although the treatment remains under investigation, these early results offer encouragement for those considering participation in a trial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

DuoCAR20.19.22-D95 is unique because it employs an innovative CAR T-cell therapy approach that targets multiple antigens—CD20, CD19, and CD22—simultaneously. Unlike standard treatments for Non-Hodgkin's Lymphoma, which typically involve chemotherapy, monoclonal antibodies, or radiation therapy, this treatment leverages genetically engineered T cells to recognize and attack cancer cells directly. Researchers are excited about this method because it has the potential to enhance treatment precision and effectiveness while minimizing damage to healthy cells, offering hope for better outcomes with fewer side effects.

What evidence suggests that DuoCAR20.19.22-D95 might be an effective treatment for Non-Hodgkin's Lymphoma?

Research has shown that DuoCAR20.19.22-D95, a new type of CAR T-cell therapy, may help treat certain B-cell cancers, such as Non-Hodgkin's lymphoma, that have returned after treatment. In an earlier study, 65.2% of patients responded to the treatment, and 56.5% experienced a complete response, meaning their cancer was no longer detectable. This therapy modifies a patient's own T cells to better identify and destroy cancer cells by recognizing specific proteins on them. Early results suggest this method could benefit patients who haven't improved with other treatments. While more research is needed, these initial findings offer hope for better outcomes. Participants in this trial will receive DuoCAR20.19.22-D95 following lymphodepletion chemotherapy. ^{3 5 6 7 8}

Published Research Related to This Trial

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.

Adapter CAR T Cell Therapy for the Treatment of B-Lineage Lymphomas. Atar, D., Mast, AS., Scheuermann, S., et al.[2022]

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.

Anti-CD19 chimeric antigen receptor T-cell therapy in B-cell lymphomas: current status and future directions. Chavez, JC., Yassine, F., Sandoval-Sus, J., et al.[2022]

The study developed trispecific duoCAR-T cells that target three different B cell leukemia antigens (CD19, CD20, and CD22) to overcome the problem of antigen loss in patients with leukemia and lymphoma, showing promise in preventing relapse.

In mouse models, these duoCAR-T cells effectively rejected tumors composed of various B cell lymphoma variants, while traditional monoCAR-T cells targeting only one antigen failed to prevent tumor progression, highlighting the efficacy of multispecific targeting.

In a study of 16 patients with relapsed, refractory B-cell malignancies treated with LV20.19 CAR-T therapy, the two-year progression-free survival (PFS) was 44% and overall survival (OS) was 69%, indicating promising long-term outcomes.

Factors such as lower in vivo CAR-T expansion and high metabolic tumor volume were linked to late relapse and poorer early treatment response, suggesting that these could be important predictors for patient outcomes.

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.

In a study of 182 patients with relapsed/refractory large B-cell lymphoma, novel CAR T-cell therapies showed varying efficacy and safety compared to the FDA-approved Yescarta, with some constructs like tandem CD19.CD20.4-1BBζ demonstrating favorable outcomes.

While some experimental CARs had improved safety profiles, they did not consistently outperform Yescarta in terms of progression-free survival, indicating that further research is needed to establish the best treatment options.

Dual-targeting CAR-T cell therapy shows promising efficacy in treating B cell malignancies, with a 77% overall response rate and 52% complete response rate in patients with B cell non-Hodgkin lymphoma (B-NHL), and a 92% complete response rate in patients with B cell acute lymphoblastic leukemia (B-ALL).

The therapy has a manageable safety profile, with grade ≥3 cytokine release syndrome occurring in 14% of B-NHL patients and 11% of B-ALL patients, indicating that while there are risks, the benefits may outweigh them for many patients.

Chimeric antigen receptor (CAR)-T cell therapy, specifically targeting CD19, has shown promising results in treating non-Hodgkin lymphomas (NHLs) resistant to standard therapies, leading to FDA and EMA approvals for tisagenlecleucel and axicabtagene ciloleucel.

While CAR-T cell therapy can cause significant adverse events like cytokine release syndrome and neurological toxicity, these effects are manageable with proper medical support, highlighting the importance of trained teams in administering this novel treatment.

In a study of 16 patients with relapsed/refractory aggressive B-cell lymphoma, bispecific CAR T cells targeting both CD19 and CD22 showed a high efficacy, with 87.5% achieving an objective response and 62.5% achieving complete response.

The treatment demonstrated a favorable safety profile, with only one patient experiencing severe cytokine-release syndrome, and no cases of neurotoxicity, suggesting that this dual-targeted approach may be a safe and effective option for lymphoma therapy.
