What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines how a new combination of drugs works for individuals with HIV-positive diffuse large B-cell lymphoma, a cancer affecting the lymphatic system. The study aims to determine the optimal dose and assess how effectively these drugs work together to inhibit the growth and spread of cancer cells. This trial may suit someone who is HIV-positive and diagnosed with stage II-IV diffuse large B-cell lymphoma. As a Phase 1 trial, the research focuses on understanding the treatment's effects in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial requires that participants not be on certain medications, including some antiretroviral drugs like cobicistat, indinavir, or ritonavir, or any drugs that strongly inhibit CYP3A4. If you are on these medications, you must switch to a different regimen at least one week before starting the trial.

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

Research shows that the drug combination used in this trial, R-da-EPOCH, has undergone previous testing. Studies have found that this mix can help achieve long-lasting remission in patients with aggressive B-cell lymphomas. This is encouraging for safety, as these drugs work well together in other lymphoma treatments.

Ibrutinib, one of the drugs in this trial, stops cancer cells from growing. It has been used in other treatments, and patients usually tolerate it well. While side effects can occur, they are often manageable.

The other drugs in the trial—rituximab, etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride—are commonly used in chemotherapy. Many patients have taken these drugs before, and doctors understand their side effects well.

This trial is in its early stages (Phase 1), so researchers are still determining the best dose and possible side effects of this combination. However, since these drugs have been used before, some safety knowledge already exists. Always consult your doctor if considering joining a trial, as they can provide advice based on your health. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about this combination chemotherapy for Diffuse Large B-Cell Lymphoma because it introduces ibrutinib, a novel ingredient not typically found in standard treatments. While traditional therapies often rely on drugs like rituximab, cyclophosphamide, and doxorubicin, this regimen combines these with ibrutinib, which specifically targets and blocks the Bruton's tyrosine kinase (BTK) pathway. This mechanism is important because BTK plays a crucial role in the survival and proliferation of lymphoma cells. By effectively inhibiting this pathway, the treatment has the potential to offer improved outcomes and a new option for patients with this type of lymphoma.

What evidence suggests that this trial's treatments could be effective for diffuse large B-cell lymphoma?

In this trial, participants will receive a combination of treatments, including ibrutinib with rituximab and other chemotherapy drugs. Studies have shown that this combination may improve treatment results for diffuse large B-cell lymphoma. Ibrutinib blocks certain proteins that help cancer cells grow, while rituximab, a type of targeted therapy, stops cancer cells from spreading. Other drugs, such as etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride, attack cancer cells by killing them or stopping them from dividing. Together, these drugs aim to fight the cancer from multiple angles, offering hope for better outcomes in treating this type of lymphoma. ^{1 4 6 7 8}

In a study of 20 patients with untreated poor prognosis diffuse large B-cell lymphoma (DLBCL), the two-weekly dose-adjusted EPOCH-like chemotherapy (DA-EDOCH14-R) showed a promising three-year progression-free survival (PFS) rate of 95%, compared to 74% in a previous trial with a three-weekly regimen.

The treatment was well-tolerated with manageable toxicity and no therapy-related deaths, highlighting its safety, especially for patients with a high-risk prognosis (age-adjusted International Prognostic Index of 3), where PFS reached 100% compared to just 30% in the previous trial.

In a study of 70 patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) treated with R-CEOP (rituximab, cyclophosphamide, etoposide, vincristine, and prednisone), the treatment showed comparable outcomes in terms of time to progression and disease-specific survival when matched against a control group of 140 patients treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone).

Although R-CEOP demonstrated similar progression-free and disease-specific survival rates, it was associated with a lower overall survival rate (30% vs 49% for R-CHOP), likely due to the higher comorbidities and frailty in the R-CEOP group, indicating that while R-CEOP is a viable alternative for patients who cannot tolerate anthracyclines, it may not be as effective overall.

The combination treatment of epratuzumab and rituximab with standard CHOP chemotherapy (ER-CHOP) was feasible for patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL), with a high overall response rate of 87% and a complete response rate of 67% among 15 patients.

Despite a high incidence of grade 3 or 4 neutropenia (93% of patients), there were no severe infusion-related toxicities, and the treatment showed promising survival rates with 1-year progression-free survival (PFS) at 93% and overall survival (OS) at 100% at a median follow-up of 30 months.

In a study of 1,807 patients with diffuse large B-cell lymphoma (DLBCL) treated in Chile, the addition of rituximab to the standard CHOP regimen significantly improved overall survival rates, with 5-year survival at 66% for R-CHOP compared to 48% for CHOP alone.

The long-term benefits of R-CHOP were evident, with a 10-year survival rate of 53% versus 35% for CHOP, demonstrating that rituximab not only enhances treatment efficacy but also justifies its cost in national health protocols.

In a study of 40 patients with low-grade or follicular B-cell non-Hodgkin's lymphoma, the combination of Rituxan (Rituximab) and CHOP chemotherapy resulted in a high overall response rate of 95%, with 55% achieving complete remission.

The combination therapy showed promising safety, with common side effects being manageable, and it also indicated potential for clearing minimal residual disease, as evidenced by the conversion of the bcl-2 translocation from positive to negative in several patients.

In a study of 115 patients with Waldeyer's ring diffuse large B-cell lymphoma, those treated with dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin plus rituximab (DA-EPOCH-R) showed significantly better progression-free survival (PFS) and overall survival (OS) compared to those receiving standard R-CHOP treatment, with 2-year PFS rates of 90.1% versus 80.5%.

The DA-EPOCH-R treatment was associated with fewer deaths (2 out of 42 patients) compared to R-CHOP (9 out of 42 patients) during a median follow-up of 45 months, while both treatments had similar clinical responses and treatment-related toxicities, indicating that DA-EPOCH-R is a safer and more effective option for this patient population.

In a randomized trial of 118 patients with advanced diffuse lymphocytic lymphoma, the combination of the drug VP-16-213 with doxorubicin resulted in a higher complete remission rate of 54%, compared to 39% with VP-16-213 alone and 26% with VP-16-213 combined with cyclophosphamide.

The study found that combining VP-16-213 with cyclophosphamide led to significantly lower remission rates, suggesting that doxorubicin is a more effective partner for VP-16-213 in treating this type of lymphoma.

The study indicates that adding acalabrutinib to R-CHOP therapy poses a low risk of drug-drug interactions (DDIs) with vincristine, suggesting it may not significantly increase the risk of peripheral neuropathy associated with vincristine treatment.

In contrast, the BTK inhibitor ibrutinib was found to increase vincristine exposure in muscle tissue, indicating a higher potential for toxicity when used with vincristine compared to acalabrutinib.

In a pooled analysis of 150 patients with HIV-associated aggressive B-cell non-Hodgkin lymphoma, those treated with R-EPOCH showed significantly better event-free survival (EFS) and overall survival (OS) compared to those receiving R-CHOP, particularly in patients with a CD4 count ≥100/μL.

Patients with CD4 counts <50/μL experienced a much higher rate of treatment-related deaths (37% vs 6%), indicating that lower immune function increases the risk of lethal toxicity during treatment.
