Trial Summary

What is the purpose of this trial?

This trial tests a new drug, epcoritamab, for children and young adults with aggressive B-cell cancers that have come back or not responded to other treatments. The drug is given as an injection under the skin periodically. The study will check how safe the drug is and how well it works over several years.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications, but you cannot be receiving any anti-cancer therapy, including chemotherapy, radiotherapy, or other investigational agents, while participating.

What data supports the effectiveness of the drug Epcoritamab for B-cell lymphoma?

Epcoritamab has shown strong anti-tumor activity in patients with different types of B-cell lymphoma, including diffuse large B-cell lymphoma, follicular lymphoma, and mantle cell lymphoma, even in those who did not respond to previous treatments. In a study, 55.6% of patients with relapsed or refractory diffuse large B-cell lymphoma responded to the drug, with 44.4% achieving a complete response. ^{1 2 3 4 5}

What is known about the safety of Epcoritamab for B-cell lymphoma?

Epcoritamab has shown a manageable safety profile in patients with relapsed or refractory diffuse large B-cell lymphoma. Common side effects include cytokine release syndrome (a reaction that can cause fever and low blood pressure), injection-site reactions, infections, and low white blood cell counts, but these were mostly mild and resolved without stopping treatment. ^{1 2 4 5 6}

How is the drug Epcoritamab unique for treating B-cell lymphoma?

Epcoritamab is unique because it is a bispecific antibody that engages T-cells to target and kill cancerous B-cells, and it is administered subcutaneously (under the skin), which is different from many other treatments that are given intravenously (through a vein). This drug is particularly promising for patients with relapsed or refractory B-cell lymphoma who have not responded to other treatments. ^{1 2 3 4 5}

Findings from Research

Epcoritamab, a bispecific antibody targeting CD3 and CD20, showed a 63.1% overall response rate in 157 patients with relapsed or refractory large B-cell lymphoma, indicating its efficacy in this challenging patient population.

The treatment was generally well-tolerated, with manageable side effects; however, cytokine release syndrome was common (49.7%), and there was one reported fatality due to immune effector cell-associated neurotoxicity syndrome.

Epcoritamab, a bispecific antibody targeting CD3 and CD20, was found to be safe and well-tolerated in 73 patients with relapsed or refractory B-cell non-Hodgkin lymphoma, with no dose-limiting toxic effects and a recommended phase 2 dose established at 48 mg.

The treatment showed promising efficacy, with an overall response rate of 68% in patients with diffuse large B-cell lymphoma and 90% in those with follicular lymphoma, indicating its potential as a viable therapy for these difficult-to-treat conditions.

Epcoritamab, a bispecific antibody targeting CD3 and CD20, demonstrated a 55.6% overall response rate and a 44.4% complete response rate in 36 Japanese patients with relapsed or refractory CD20+ B-cell non-Hodgkin's lymphoma after a median follow-up of 8.4 months.

The treatment had a manageable safety profile, with cytokine release syndrome being the most common adverse event (83.3%), primarily low grade, and all cases resolved without leading to treatment discontinuation.

Subcutaneous epcoritamab monotherapy in Japanese adults with relapsed/refractory diffuse large B-cell lymphoma. Izutsu, K., Kumode, T., Yuda, J., et al.[2023]

Epcoritamab is a bispecific antibody that targets CD3 and CD20, designed for treating relapsed or refractory diffuse large B-cell lymphoma (DLBCL), and received conditional approval in the USA on May 19, 2023, for adult patients after at least two prior therapies.

The drug has also received a positive opinion in the EU and is under review in Japan, indicating its potential as a significant treatment option for patients with difficult-to-treat B-cell non-Hodgkin lymphoma subtypes.

Epcoritamab: First Approval. Frampton, JE.[2023]

The combination of pembrolizumab and vorinostat was found to be tolerable in patients with relapsed/refractory B-cell lymphomas, although there were serious adverse events, including one case of Stevens-Johnson syndrome that led to a fatal infection.

The treatment showed promising efficacy, especially in primary mediastinal B-cell lymphoma (PMBL), with a complete response rate of 80% and overall response rate of 80%, while overall response rates for other non-PMBL diffuse large B-cell lymphoma (DLBCL) were lower at 33%.
