Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications, but you cannot take strong CYP3A inhibitors/inducers or warfarin. It's best to discuss your current medications with the study team.

What data supports the effectiveness of the VIPOR regimen drugs for CNS-involved B-cell lymphoma?

The combination of ibrutinib and venetoclax has shown promising results in treating other types of B-cell lymphomas, such as mantle cell lymphoma, with high response rates and complete responses in some patients. This suggests potential effectiveness for similar conditions. ^{1 2 3 4 5}

What safety data exists for the VIPOR Regimen components in humans?

Ibrutinib can cause bleeding and atrial fibrillation (irregular heartbeat), while venetoclax may lead to tumor lysis syndrome (a condition where cancer cells break down rapidly, potentially harming the kidneys). These side effects can be severe and may require dose adjustments or special monitoring. ^{1 3 6 7 8}

What makes the VIPOR regimen unique for treating CNS-involved B-cell lymphoma?

The VIPOR regimen is unique because it combines multiple drugs, including ibrutinib, lenalidomide, obinutuzumab, prednisone, and venetoclax, which target different pathways involved in B-cell lymphoma. This combination aims to enhance treatment effectiveness by using a multi-faceted approach, potentially offering benefits over traditional single-agent therapies. ^{1 2 9 10 11}

What is the purpose of this trial?

This trial uses a combination of drugs called VIPOR-Nivo to treat adults with specific aggressive brain lymphomas that are hard to treat. The drugs work together to kill cancer cells and boost the immune system.

Findings from Research

Ibrutinib, idelalisib, and venetoclax are novel oral therapies for chronic lymphocytic leukemia that provide unique clinical benefits compared to traditional treatments, but they also come with specific safety concerns and logistical challenges.

Each of these agents has distinct adverse effects: ibrutinib can cause bleeding and atrial fibrillation, idelalisib may lead to hepatotoxicity, and venetoclax carries a risk of tumor lysis syndrome, necessitating careful monitoring and potential dose adjustments.

Pharmacokinetic and Pharmacodynamic Considerations in the Treatment of Chronic Lymphocytic Leukemia: Ibrutinib, Idelalisib, and Venetoclax. Waldron, M., Winter, A., Hill, BT.[2021]

In a phase 3 trial with 523 patients, the combination of ibrutinib and venetoclax significantly improved progression-free survival compared to the traditional FCR treatment, with only 12 patients experiencing disease progression or death in the ibrutinib-venetoclax group versus 75 in the FCR group.

The study also found that 65.9% of patients on ibrutinib-venetoclax achieved undetectable measurable residual disease (MRD) in bone marrow after 5 years, indicating effective disease control, although there was a higher incidence of serious cardiac adverse events in this group compared to FCR.

In a safety run-in cohort of 21 patients with relapsed/refractory mantle cell lymphoma, the combination of ibrutinib and venetoclax showed an impressive overall response rate of 81%, with 62% achieving a complete response after a median follow-up of 31 months.

The study indicated that concurrent administration of ibrutinib and venetoclax is safe, with only three dose-limiting toxicities observed and no new safety concerns, allowing the trial to proceed without an ibrutinib lead-in.

In a retrospective study of 22 patients with chronic lymphocytic leukaemia (CLL) who progressed on ibrutinib, the combination of ibrutinib and venetoclax resulted in a median overall survival of 47.1 months, indicating potential efficacy in this challenging patient group.

For 11 patients with double-refractory CLL, the same combination therapy led to a median overall survival of 27.0 months, suggesting that this treatment may provide a valuable option for patients who have limited alternatives after failing standard therapies.

In a retrospective analysis of 4 patients with relapsed/refractory mantle-cell lymphoma (MCL), the combination of ibrutinib and venetoclax resulted in a 50% complete response rate, demonstrating its potential efficacy as a treatment option.

All patients who responded to the treatment were able to undergo allogeneic stem cell transplantation, with two patients remaining in complete remission, indicating that this combination therapy may be a viable bridge to transplant for MCL patients.

Ibrutinib, idelalisib, and venetoclax are effective B cell signaling agents for treating non-Hodgkin's lymphomas, but they come with distinct toxicity profiles that differ from traditional chemotherapy.

Ibrutinib can increase the risk of atrial fibrillation and bleeding, while idelalisib requires close monitoring of liver function and infection risks, and venetoclax necessitates careful monitoring to prevent tumor lysis syndrome.

In the phase III CLL14 trial, a 12-month treatment with venetoclax combined with obinutuzumab significantly improved progression-free survival and rates of undetectable minimal residual disease compared to traditional chemoimmunotherapy with chlorambucil and obinutuzumab in patients with untreated chronic lymphocytic leukaemia.

Venetoclax + obinutuzumab is a well-tolerated, chemotherapy-free treatment option for CLL, with manageable side effects like neutropenia, making it suitable for patients who cannot undergo intensive chemotherapy.

The combination of venetoclax with rituximab showed remarkable efficacy and a manageable safety profile in treating chronic lymphocytic leukemia (CLL), both in relapsed/refractory cases and as a first-line therapy for high-risk patients.

Similarly, the combination of ibrutinib with venetoclax also demonstrated striking efficacy, suggesting that these combinations could become new standard treatment options for CLL.
