Trial Summary

What is the purpose of this trial?

This study is being performed as a single-arm open-label study in order to rapidly provide information on the potential benefits of the combination of pembrolizumab and lenvatinib in participants with previously untreated advanced/metastatic non-clear cell renal cell carcinoma.

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, it mentions that you must not have received prior systemic therapy for advanced kidney cancer and should have controlled blood pressure, which might imply some restrictions. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the drug combination of pembrolizumab and lenvatinib for kidney cancer?

Research shows that the combination of pembrolizumab and lenvatinib is effective in treating advanced renal cell carcinoma, with studies indicating improved survival rates compared to other treatments like sunitinib. This combination has shown promise in both clear-cell and non-clear-cell types of kidney cancer. ^{1 2 3 4 5}

Is the combination of Pembrolizumab and Lenvatinib safe for humans?

The combination of Pembrolizumab and Lenvatinib has been studied for safety in patients with advanced kidney cancer and other solid tumors. Common adverse reactions (side effects) have been identified, and strategies for managing these reactions have been reviewed, indicating that while there are side effects, they are being actively managed in clinical settings. ^{2 3 5 6 7}

What makes the drug combination of pembrolizumab and lenvatinib unique for kidney cancer?

The combination of pembrolizumab and lenvatinib is unique because it pairs an immune checkpoint inhibitor (pembrolizumab) with a multikinase inhibitor (lenvatinib), offering a novel approach that has shown improved survival outcomes compared to traditional treatments like sunitinib for advanced renal cell carcinoma. ^{1 2 3 4 6}

Findings from Research

The combination of lenvatinib and pembrolizumab demonstrated promising antitumor activity in patients with metastatic renal cell carcinoma (RCC), with an objective response rate of 72.7% in treatment-naive patients and 55.8% in those previously treated with immune checkpoint inhibitors, based on a study of 143 patients.

While the treatment showed efficacy, it also had a manageable safety profile, with 57% of patients experiencing grade 3 treatment-related adverse events, primarily hypertension, and 7% experiencing grade 4 events, indicating that careful monitoring is necessary during treatment.

In the KEYNOTE-B61 trial involving 158 patients with advanced non-clear-cell renal cell carcinoma, the combination of pembrolizumab and lenvatinib demonstrated a 49% objective response rate, indicating significant antitumor activity as a first-line treatment.

The safety profile was consistent with previous studies, with 51% of patients experiencing grade 3-4 treatment-related adverse events, primarily hypertension, but no deaths were attributed to the treatment itself.

In a phase 1b study involving 6 Japanese patients with metastatic solid tumors, the combination of lenvatinib and pembrolizumab was well-tolerated, with no dose-limiting toxicities reported.

The treatment showed promising antitumor activity, with an objective response rate of 33.3%, particularly in patients with urothelial cancer, indicating potential efficacy for this combination therapy.

In a phase 3 trial with 1069 patients, the combination of lenvatinib and pembrolizumab significantly improved progression-free survival compared to sunitinib, with a median of 23.9 months versus 9.2 months, indicating a strong efficacy of this regimen.

Lenvatinib plus pembrolizumab also resulted in longer overall survival compared to sunitinib, while the combination of lenvatinib and everolimus did not show a survival advantage over sunitinib. However, both lenvatinib combinations had a high incidence of grade 3 or higher adverse events, similar to sunitinib.

In a subset analysis of the CLEAR study involving 73 Japanese patients with advanced renal cell carcinoma, the combination of lenvatinib and pembrolizumab showed significantly longer progression-free survival (22.1 months) compared to sunitinib (10.9 months).

The combination therapy also resulted in a higher objective response rate (69.0% vs. 45.2%) and longer median duration of response (20.3 months vs. 9.1 months), although it was associated with a higher incidence of grade ≥3 treatment-emergent adverse events (95.2% vs. 87.1%).

In the CLEAR study involving 352 patients, the combination of lenvatinib and pembrolizumab showed a manageable safety profile, with common adverse reactions including fatigue (63.1%), diarrhea (61.9%), and hypertension (56.3%).

Most adverse reactions occurred within approximately 5 months of starting treatment, and effective management strategies such as monitoring and dose modifications were identified to ensure patient safety and support ongoing treatment.

In a phase 3 study involving 1069 patients with advanced renal cell carcinoma, the combination of lenvatinib and pembrolizumab showed similar or better health-related quality of life (HRQOL) outcomes compared to sunitinib, particularly in terms of time to definitive deterioration.

Patients receiving lenvatinib plus pembrolizumab experienced longer median times to deterioration in quality of life measures, indicating that this combination therapy not only improves survival but also maintains a better quality of life for patients.
