Trial Summary

What is the purpose of this trial?

This study is an open-label Phase II trial of non-Hodgkin lymphoma patients receiving initial treatment with the immunomodulatory agent, pembrolizumab, plus low-dose (4 Gy x 5) involved-site radiotherapy. Eligible patients will have r/r disease with at least 2 sites of measurable disease (≥1.0 cm), and must be eligible for treatment with pembrolizumab. Biosamples (blood and, where available, tumor) will be collected as outlined below. Pembrolizumab will be continued after RT until disease progression, drug intolerance, or at the discretion of the treating medical oncologist.

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

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have received certain cancer therapies or live vaccines shortly before starting the trial.

What data supports the effectiveness of the drug pembrolizumab for treating lymphoma?

Pembrolizumab has shown significant effectiveness in treating Hodgkin Lymphoma and promising responses in some subtypes of non-Hodgkin Lymphoma that share genetic features with Hodgkin Lymphoma. Early phase trials suggest it is effective and safe as a single agent in these cases. ^{1 2 3 4 5}

How is the drug Pembrolizumab different from other treatments for lymphoma?

Pembrolizumab is unique because it works by blocking a protein called PD-1, which helps the immune system recognize and attack cancer cells, unlike other treatments like Rituximab that target specific antigens on cancer cells directly. ^{6 7 8 9 10}

Findings from Research

Pembrolizumab, a PD-1 inhibitor, has demonstrated clinical effectiveness in treating various solid tumors, particularly in patients with PD-L1-positive non-small-cell lung cancer and unresectable/metastatic melanoma.

Early-phase trials and ongoing studies are focused on further confirming the clinical benefits of pembrolizumab in thoracic malignancies, highlighting its potential as a significant treatment option in cancer therapy.

In a phase II trial involving 15 patients with resectable non-small cell lung cancer (NSCLC), neoadjuvant treatment with pembrolizumab showed a major pathologic response in 27% of patients, indicating promising antitumor activity before surgery.

The treatment was found to be feasible and safe, with only 33% of patients experiencing moderate adverse events, and no postoperative mortality, suggesting that pembrolizumab does not compromise surgical outcomes.

Pembrolizumab, a monoclonal antibody targeting PD-1, has shown significant clinical efficacy in treating Hodgkin Lymphoma and promising early results in certain subtypes of Non-Hodgkin Lymphoma, particularly those with genetic similarities to HL.

Current data suggest that pembrolizumab has a favorable safety profile and efficacy as a single agent in treating diffuse large B cell lymphomas, with future strategies likely to focus on biomarker-driven approaches and combination therapies.

Pembrolizumab for the treatment of diffuse large B-cell lymphoma. Sheikh, S., Kuruvilla, J.[2020]

In a study of 59 patients with relapsed/refractory extranodal natural killer/T-cell lymphoma treated with pembrolizumab, the overall response rate was 40.7%, with 28.8% achieving a complete response, indicating its potential efficacy as a salvage therapy.

While pembrolizumab showed modest effectiveness, it was associated with some grade 3 or 4 adverse events in 20.3% of patients, with neutropenia being the most common, suggesting that while it can be beneficial, monitoring for side effects is important.

Pembrolizumab, a PD-1 inhibitor used in cancer treatment, can lead to rare but serious immune-related adverse events, including type 1 diabetes mellitus, occurring in about 0.2% of cases.

A review of 42 cases revealed that patients may develop diabetic ketoacidosis during treatment, highlighting the need for blood glucose monitoring and awareness of this potential side effect among clinicians.

In a phase I study involving 67 patients with relapsed/refractory follicular lymphoma and other CD20+ non-Hodgkin lymphomas, the combination of utomilumab and rituximab showed a favorable safety profile, with no dose-limiting toxicities and mostly mild adverse events like fatigue.

The treatment demonstrated clinical activity with an objective response rate of 21.2%, including complete and partial responses, suggesting that the effectiveness may depend on the patient's immune function.

Rituximab has significantly improved outcomes for patients with Non-Hodgkin's lymphoma (NHL), particularly in aggressive forms like diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL).

The treatment is generally well-tolerated by patients and has been shown to be cost-effective, making it a valuable option in both initial and relapsed cases of B cell NHL.

Rituximab, an anti-CD20 monoclonal antibody, demonstrated a 43% overall response rate in a phase II trial involving 31 patients with bulky relapsed or refractory low-grade or follicular non-Hodgkin's lymphoma, indicating its efficacy as a treatment option.

The treatment was well-tolerated, with no patients discontinuing due to adverse events, and it showed a median time to progression of 8.1 months, highlighting its safety and potential for managing this type of cancer.

In a phase II study involving 37 patients with relapsed or refractory low-grade or follicular B-cell non-Hodgkin's lymphoma, Rituximab was found to be well tolerated, with most adverse events being mild and decreasing with subsequent infusions.

The treatment resulted in a 57% overall response rate, with 14% achieving a complete response and 43% a partial response, indicating significant clinical activity and suggesting that extended Rituximab treatment may be effective for this patient group.

In a phase II study involving 54 patients with aggressive B-cell lymphomas, rituximab demonstrated significant clinical activity, achieving an overall response rate of 31%, with complete responses in 9% and partial responses in 22% of patients.

The treatment was well-tolerated, with mild adverse events primarily related to infusion syndrome, indicating that rituximab could be a safe option for patients with diffuse large B-cell lymphoma (DLCL) and mantle cell lymphoma (MCL).
