What You Need to Know Before You Apply

What is the purpose of this trial?

To learn if loncastuximab tesirine (called "lonca" in this informed consent form) can help to control large B-cell lymphoma that is relapsed or refractory after receiving CAR T-cell therapy. The safety and possible effects of the study therapy will also be studied.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. It's best to discuss your specific medications with the study team to get a clear answer.

What safety data exists for CAR T-cell therapy, including Loncastuximab Tesirine, in humans?

CAR T-cell therapy, including treatments like Loncastuximab Tesirine, has shown promise in treating certain cancers but comes with potential safety concerns. Common side effects include cytokine release syndrome (a severe immune reaction) and neurological issues, which can be serious but are manageable with proper medical care. Other risks include infections, cardiac effects, and nonrelapse mortality, which require careful monitoring and management by healthcare professionals. ^{1 2 3 4 5}

How is loncastuximab tesirine different from other drugs for non-Hodgkin's lymphoma?

Loncastuximab tesirine is unique because it is an antibody-drug conjugate that specifically targets CD19, a protein found on B-cells, and delivers a powerful cancer-killing agent directly to these cells. This targeted approach can be more effective and potentially have fewer side effects compared to traditional chemotherapy, which affects both cancerous and healthy cells. ^{6 7 8 9 10}

What data supports the effectiveness of the drug Loncastuximab Tesirine for treating Non-Hodgkin's Lymphoma?

Research shows that Loncastuximab Tesirine, a drug targeting CD19 on cancer cells, has been effective in treating relapsed or refractory diffuse large B-cell lymphoma, a type of Non-Hodgkin's Lymphoma. In clinical trials, it showed an overall response rate of about 48%, with some patients achieving complete remission, and it was approved by the FDA for this use due to its demonstrated safety and effectiveness. ^{6 7 10 11 12}

Published Research Related to This Trial

In a phase 2 trial involving 145 patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), loncastuximab tesirine demonstrated a significant overall response rate of 48.3%, indicating its effectiveness as a treatment option for this challenging patient population.

The treatment was associated with an acceptable safety profile, with serious adverse events occurring in 39% of patients, but none were directly linked to loncastuximab tesirine, suggesting it may be a safe option for heavily pretreated patients.

In a study involving 80 patients from the LOTIS-2 trial, loncastuximab tesirine (Lonca) demonstrated a significantly higher overall response rate (53.4%) compared to chemoimmunotherapy (CIT) treatments (40.3%) for relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL).

Lonca also showed improved overall survival, with a median survival of 10.8 months compared to 6.4 months for CIT, indicating it may be a more effective treatment option for patients with R/R DLBCL.

Loncastuximab tesirine-lpyl, an anti-CD19 antibody-drug conjugate, has shown a 48.3% overall response rate in patients with relapsed, refractory diffuse large B-cell lymphoma during the phase II LOTIS-2 trial, indicating its efficacy as a treatment option.

The drug demonstrated a tolerable safety profile with common side effects including neutropenia and thrombocytopenia, and no new safety concerns were identified in the phase II trial, suggesting it is safe for further testing in various non-Hodgkin lymphoma subtypes.

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.

CAR-T cell therapies targeting CD19 have shown the ability to induce long-lasting remissions and improve disease-free survival in patients with treatment-resistant B cell malignancies, highlighting their efficacy in specific cancer types.

Immune checkpoint inhibitors (ICIs) have also demonstrated the potential for durable remissions and extended survival in patients with melanoma, Hodgkin's lymphoma, and non-small cell lung cancer, although both CAR-T and ICI therapies can lead to significant toxicities, including fatalities.

Cancer immunotherapy, including HER2-targeted therapies like trastuzumab, immune checkpoint inhibitors, and CAR-T cell therapy, has significantly improved cancer patient outcomes by harnessing the immune system to target and kill cancer cells.

While trastuzumab is effective for HER2-positive cancers, it can cause reversible left ventricular dysfunction, whereas immune checkpoint inhibitors and CAR-T therapy may lead to serious cardiac side effects, including myocarditis and cytokine release syndrome, which can be life-threatening.

In a study of 957 patients receiving CAR T-cell therapy for relapsed/refractory large B-cell lymphomas, the overall nonrelapse mortality (NRM) rate was 5.0%, with the majority of deaths occurring later than 28 days post-infusion, primarily due to infections.

Risk factors for increased NRM included diabetes and elevated ferritin levels at the time of lymphodepletion, which can help guide physicians in selecting and managing patients to minimize these risks.

Adoptive T cell therapy (ACT) is a promising and personalized cancer treatment that has shown significant effectiveness, particularly with TIL, TCR, and CAR-engineered T cells, leading to FDA approvals for certain B-cell malignancies.

Despite its potential, only a small percentage of patients with advanced cancers currently benefit from ACT due to treatment-related toxicities, highlighting the need for improved safety measures and an international consensus on toxicity management.

In a study of 35 adults with relapsed or refractory B-cell acute lymphoblastic leukemia, loncastuximab tesirine, an antibody-drug conjugate targeting CD19, showed promising preliminary clinical activity with 3 patients achieving complete responses at different doses.

The treatment was generally well-tolerated, with common side effects including nausea and febrile neutropenia, but no treatment-related deaths were reported, indicating a favorable safety profile despite a high incidence of grade ≥3 adverse events.
