Trial Summary

What is the purpose of this trial?

This study is investigating a new administration schedule of Rituximab, Cyclophosphamide, Doxorubicin, Vincristine, Prednisone (R-CHOP) chemotherapy for participants with Diffuse Large B-Cell Lymphoma (DLBCL), focusing on an underserved elderly population (aged 75 and up; certain participants 70-74 may be eligible) that is often excluded from clinical trials. Participants can expect to be on study for 2.5 years (treatment for 6 months and 2 years of post treatment follow-up).

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you have hepatitis B, you will need to take entecavir as part of the trial requirements.

What data supports the effectiveness of the drug R-CHOP for treating lymphoma?

Research shows that adding rituximab to the CHOP regimen (cyclophosphamide, doxorubicin, vincristine, and prednisone) improves outcomes for aggressive B-cell lymphoma, making R-CHOP a first-line treatment for this condition. ^{1 2 3 4 5}

Is Split-Dose R-CHOP generally safe for humans?

The R-CHOP treatment, which includes drugs like rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, has been studied for safety in patients with non-Hodgkin's lymphoma. It can cause severe side effects, including heart problems due to doxorubicin, but safety measures and monitoring can help manage these risks. Overall, the safety profile is considered comparable to similar treatments, with a high incidence of treatment-related side effects. ^{6 7 8 9 10}

What makes the Split-Dose R-CHOP treatment unique for lymphoma?

The Split-Dose R-CHOP treatment for lymphoma is unique because it involves administering the standard R-CHOP regimen in a split-dose format, which may help manage side effects and improve patient tolerance. This approach differs from the traditional R-CHOP schedule, which is typically given in full doses at regular intervals. ^{4 11 12 13 14}

Findings from Research

In a study of 50 patients treated with R-CHOP-14 for aggressive B-cell lymphoma, 82% achieved a complete or improved response, indicating high efficacy of this treatment regimen.

Despite its effectiveness, R-CHOP-14 was associated with significant toxicities, including grade 3-4 neutropenia in 32% of patients and peripheral neuropathy in 45%, highlighting the need for careful monitoring of side effects.

The CHOEA-7 chemotherapy regimen, which includes cyclophosphamide, doxorubicin, vincristine, etoposide, and ara-C, has shown excellent results in treating patients with CD 20-positive non-Hodgkin's lymphoma.

Adding rituximab to the CHOEA-7 regimen (RCHOEA-7) further enhances treatment efficacy, indicating a promising approach for improving outcomes in this patient population.

In a study of 112 patients under 65 years old with diffuse large B-cell lymphoma, the combination of rituximab and high-dose sequential chemotherapy led to an impressive 80% clinical remission rate, demonstrating its efficacy in treating this aggressive cancer.

At a median follow-up of 48 months, 78% of patients remained alive and 73% were in continuous remission, indicating that this treatment significantly improves life expectancy compared to conventional chemotherapy for younger patients with higher risk scores.

The R-CHOP regimen, which includes rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, is a standard first-line treatment for diffuse large B-cell lymphoma, highlighting its importance in oncology.

Nursing implications of administering R-CHOP are significant, as the combination of these drugs requires careful monitoring for side effects and patient management during treatment.

The AMOPLACE chemotherapy regimen, which includes additional agents beyond the standard CHOP treatment, achieved a complete response rate of 68% in 60 patients with intermediate to high-grade non-Hodgkin's lymphomas, indicating its potential efficacy.

Despite its effectiveness, AMOPLACE was associated with significant myelosuppression, as 73% of patients experienced low white blood cell counts, and there were two treatment-related deaths, highlighting the need for careful monitoring of side effects.

The combination of biweekly THP-COP chemotherapy and radiotherapy resulted in a high 5-year overall survival rate of 89% and a cause-specific survival rate of 90% in 41 patients with early-stage non-Hodgkin's lymphoma.

Despite some patients experiencing grade 4 neutropenia (12%), the treatment was well-tolerated, with 93% of patients completing the chemotherapy as scheduled, indicating that this regimen is both feasible and effective for low-risk cases.

The medication instruction sheet (MIS) developed for patients receiving R-CHOP therapy effectively predicted 71% of adverse drug reactions (ADRs) during the treatment period, demonstrating its usefulness in managing these reactions.

The MIS accurately matched the onset timing of infusion reactions and peripheral neuropathy, although its effectiveness was lower for predicting thrombocytopenia-related ADRs, indicating areas for improvement in monitoring.

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 180 patients with aggressive non-Hodgkin's lymphoma, the use of dexrazoxane significantly reduced the risk of cardiac events and congestive heart failure (CHF) during treatment with the CHOP/R-CHOP regimen, with a 5-year cumulative risk of cardiac events dropping from 29% to 8% after its introduction.

Younger patients (under 60 years) also showed a lower risk of cardiac events, indicating that both dexrazoxane and age are important factors in protecting against the cardiotoxic effects of chemotherapy.

A phase 3 study involving 407 treatment-naïve patients with diffuse large B-cell lymphoma demonstrated that HLX01, a biosimilar to rituximab, has comparable efficacy to the reference drug, with overall response rates of 94.1% for HLX01 and 92.8% for rituximab, falling within the pre-defined equivalence margin.

The safety profiles of HLX01 and rituximab were similar, with nearly identical rates of treatment-emergent adverse events (99.5% vs. 99.0%) and serious adverse events (34.0% vs. 32.5%), confirming that HLX01 is a safe alternative to rituximab.

In a study involving 166 patients with aggressive B-cell lymphoma, the addition of radiotherapy (RT) to the standard R-CHOP treatment significantly improved event-free survival (EFS) for those with bulky disease, indicating that RT is beneficial for this patient group.

Patients who did not receive RT had a higher risk of disease progression and lower overall survival rates, suggesting that RT effectively mitigates the risks associated with bulky disease in elderly patients.

In a study of 250 patients with indolent non-Hodgkin lymphomas, both R-CVP and R-CHOP regimens followed by rituximab maintenance showed similar efficacy in terms of event-free survival and progression-free survival after a median follow-up of over 5 years.

R-CVP demonstrated significantly lower rates of severe adverse events compared to R-CHOP, making it a safer option for induction treatment in these patients.

In a study of 582 patients with diffuse large B-cell lymphoma (DLBCL) treated in Germany, both R-CHOP-14 and R-CHOP-21 regimens showed similar overall survival rates at 3 years, with 84% for R-CHOP-14 and 84% for R-CHOP-21.

The findings confirm previous randomized clinical trials that indicated no superiority of the dose-dense R-CHOP-14 over the standard R-CHOP-21, supporting the use of either regimen in routine clinical practice.
