What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment approach for individuals with relapsed large cell lymphoma, a type of non-Hodgkin's lymphoma. It combines chemotherapy drugs (gemcitabine, cisplatin, and dexamethasone) with a new drug, epcoritamab, administered over three cycles. After these cycles, participants may undergo additional treatments like stem cell transplants or continue with only epcoritamab if they respond well. This trial suits those who have previously received treatment for large cell lymphoma but have experienced a relapse or incomplete response. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to significant advancements in lymphoma care.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, you cannot use any standard or experimental anti-large cell lymphoma therapy within 14 days before starting the trial treatment.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that combining epcoritamab with chemotherapy drugs like gemcitabine and cisplatin is generally well-tolerated by patients with relapsed large cell lymphoma. In earlier studies, using epcoritamab with similar chemotherapy led to some expected side effects, such as cytokine release syndrome (CRS). CRS occurred in about half of the patients, but it was usually mild and did not require stopping the treatment.

Gemcitabine and cisplatin are well-known chemotherapy drugs. Patients often handle them well, but like all chemotherapy, they can cause side effects. These may include nausea, tiredness, and lower blood counts, which are common and expected with these medications.

Overall, this combination of treatments has demonstrated manageable side effects, allowing many patients to continue with their treatment plan. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for Non-Hodgkin's Lymphoma because they incorporate Epcoritamab, a unique monoclonal antibody that specifically targets CD3 and CD20, potentially enhancing the immune system's ability to fight cancer cells. Unlike traditional chemotherapy, which can affect healthy cells, Epcoritamab provides a more targeted approach, potentially reducing side effects. Additionally, the combination with GDP (Gemcitabine, Cisplatin, and Dexamethasone) and options for maintenance with Epcoritamab or advanced therapies like CAR T-cell therapy could offer more personalized and effective treatment strategies. This approach aims to improve outcomes for patients who have limited options with current standard treatments.

What evidence suggests that this trial's treatments could be effective for Non-Hodgkin's Lymphoma?

In this trial, participants will receive a combination of epcoritamab with gemcitabine, cisplatin, and dexamethasone (known as GDP) to treat relapsed large cell lymphoma. Epcoritamab is a specialized antibody that helps the immune system target and destroy cancer cells by focusing on specific proteins called CD3 and CD20. Research has shown that epcoritamab, when combined with GDP, may be promising for treating certain types of non-Hodgkin’s lymphoma, especially when other treatments have failed. The trial aims to determine whether combining epcoritamab with GDP can enhance effectiveness, as these drugs are known to work well together against lymphoma cells. Overall, evidence suggests that this treatment combination could be effective for people with relapsed large cell lymphoma. ^{1 4 5 6 7}

Published Research Related to This Trial

The combination of carboplatin and cyclophosphamide is emerging as the preferred treatment for epithelial ovarian cancer due to its effectiveness and lower toxicity compared to cisplatin plus cyclophosphamide, based on several prospective studies.

Current clinical trials are exploring high-dose carboplatin regimens and combinations with other treatments, showing promise in improving survival rates for patients with advanced ovarian cancer.

In a Phase I study involving 40 patients with urologic and gynecologic cancers, cis-diamminedichloroplatinum(II) (CIS-DDP) was found to have manageable side effects, primarily nausea, vomiting, and anorexia, which resolved quickly after stopping the treatment.

The study indicated low levels of hematopoietic and renal toxicities, with no reported cases of hearing disturbances or tinnitus, suggesting a favorable safety profile for CIS-DDP at doses of 50 mg/m2 for single administration and 20 mg/m2/day for five consecutive days.

Cis-dichlorodiammineplatinum(II) can cause serious side effects such as nephrotoxicity, gastrointestinal issues (like nausea and vomiting), and myelosuppression, highlighting the need for careful monitoring during treatment.

Other potential side effects include ototoxicity (which can lead to hearing loss), anaphylactic reactions, and peripheral neuropathies, indicating that while the drug may be effective, its safety profile requires close attention.

A phase II trial of cisdiammino-dichloro platinum (CDDP) showed significant effectiveness against testis embryonic carcinoma, ovarian carcinoma, and epidermoid cancers, particularly in head and neck and cervical cancers.

While CDDP demonstrates strong anti-cancer activity, it is associated with notable toxicity primarily affecting the digestive and renal systems, leading to its use in combination therapies for the indicated tumors.

In a phase II study, cis-dichlorodiammineplatinum(II) (CDDP) demonstrated activity as a single agent in treating non-Hodgkin's lymphoma, with 3 out of 10 patients achieving partial remission lasting 7-15 weeks.

The combination of CDDP with ICRF-159 was not effective, as none of the 8 patients treated with this combination achieved an objective response, indicating it may not be a viable treatment option.

In a study involving 25 patients with advanced Hodgkin's disease and non-Hodgkin's lymphoma, cis-dichlorodiammineplatinum(II) showed limited efficacy, resulting in one complete response and two partial responses, indicating it may have some therapeutic potential.

The treatment was associated with significant myelosuppression, particularly leukopenia and thrombocytopenia, which were more severe than in previous studies, likely due to the patients' extensive prior treatments and the presence of tumor-bearing marrow.

However, the treatment was associated with considerable adverse effects, including gastrointestinal issues in 78.5% of patients, as well as myelosuppression and renal dysfunction, highlighting the need for careful monitoring during therapy.

In a study of 69 patients with relapsed and refractory Hodgkin and Non-Hodgkin lymphoma, the GDP/R-GDP regimen effectively mobilized CD34+ stem cells in 98% of chemosensitive patients, allowing them to proceed to autologous stem cell transplantation.

The treatment demonstrated low toxicity, making it suitable for outpatient settings, and was particularly effective in patients with early-stage disease, suggesting its potential as a preferred option for stem cell mobilization.
