Combination Chemotherapy for Diffuse Large B-Cell Lymphoma
Trial Summary
What is the purpose of this trial?
This phase I trial studies the side effect and best dose of ibrutinib in combination with rituximab, etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride in treating patients with human immunodeficiency virus (HIV)-positive stage II-IV diffuse large B-cell lymphomas. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ibrutinib and etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride may work better in treating patients with HIV-positive diffuse large B-cell lymphomas.
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.
What data supports the effectiveness of the drug combination used in the clinical trial for Diffuse Large B-Cell Lymphoma?
Research shows that combining VP-16-213 (etoposide) with doxorubicin resulted in higher complete remission rates compared to using VP-16-213 alone or with cyclophosphamide. Additionally, the R-CEOP regimen, which substitutes etoposide for doxorubicin in R-CHOP, has shown curative potential in patients with DLBCL who cannot use anthracyclines, suggesting the effectiveness of these components in similar treatments.12345
Is the combination chemotherapy for diffuse large B-cell lymphoma safe for humans?
The combination chemotherapy, including drugs like rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, has been studied for safety in humans. In trials, toxicity was manageable, and there were no therapy-related deaths, although adding ibrutinib increased toxicity, including a higher chance of nerve damage (peripheral neuropathy).678910
