Trial Summary

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 immunosuppressive therapy or systemic anticancer therapy recently, and there are restrictions on recent surgeries, radiotherapy, and certain vaccines.

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

Research shows that the combination of lenvatinib and pembrolizumab has demonstrated strong anti-tumor activity and lasting responses in various solid tumors, including melanoma, especially in cases where previous treatments have failed. This combination works by blocking signals that help tumors grow and evade the immune system, making it a promising option for cancers with limited treatment choices. ^{1 2 3 4 5}

What is known about the safety of pembrolizumab and lenvatinib combination therapy?

The combination of pembrolizumab and lenvatinib has been studied for safety in various cancers, showing common side effects like high blood pressure, low thyroid function, diarrhea, nausea, vomiting, loss of appetite, fatigue, and weight loss. These side effects are consistent with what is known about each drug when used alone. ^{1 6 7 8 9}

How is the drug combination of pembrolizumab and lenvatinib unique for treating melanoma?

This drug combination is unique because it targets melanoma that has progressed despite previous treatments with PD-1 or PD-L1 inhibitors, using pembrolizumab to boost the immune response and lenvatinib to inhibit tumor blood vessel growth, offering a new option for patients with limited alternatives. ^{1 4 9 10 11}

What is the purpose of this trial?

Substudy 02D is part of a larger research study that is testing experimental treatments for melanoma, a type of skin cancer. The larger study is the umbrella study. The goal of substudy 02D is to evaluate the safety and efficacy of investigational treatment arms in programmed cell-death 1 (PD-1) naïve or PD-1 exposed participants with melanoma brain metastasis (MBM) and to identify the investigational agent(s) that, when used in combination, are superior to the current treatment options/historical control available. As of amendment 2 (effective 01DEC2022) enrollment into the treatment arm of pembrolizumab and lenvatinib has been discontinued.

Findings from Research

In the phase II LEAP-004 study involving 103 patients with advanced melanoma who had disease progression on PD-1 inhibitors, the combination of lenvatinib and pembrolizumab achieved an objective response rate of 21.4%, indicating its potential effectiveness in this challenging population.

The treatment demonstrated a median progression-free survival of 4.2 months and an overall survival of 14.0 months, with a manageable safety profile, including a 45.6% incidence of grade 3-5 adverse events, primarily hypertension.

The combination of lenvatinib, a multikinase inhibitor, and pembrolizumab, a PD-1 inhibitor, shows promising antitumor activity and durable responses in various solid tumors, as indicated by preliminary results from the LEAP clinical trial program.

This combination therapy has a manageable safety profile, suggesting it could be a valuable new treatment option for solid cancers that currently have limited therapeutic alternatives.

Optimizing the use of lenvatinib in combination with pembrolizumab in patients with advanced endometrial carcinoma. Lorusso, D., Danesi, R., Locati, LD., et al.[2023]

Combination therapy with pembrolizumab and lenvatinib is effective as a first-line treatment for clear cell renal carcinoma and as a second-line option for recurrent or metastatic endometrial carcinoma, based on data from five completed clinical trials and two ongoing trials.

This non-chemotherapy regimen helps spare patients from prolonged myelosuppression and lowers the risk of infection, making it a safer alternative for cancer treatment.

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.

The combination of pembrolizumab and lenvatinib demonstrated significantly higher objective response rates (ORRs) and progression-free survival (mPFS) compared to their individual therapies in solid cancers, with ORRs reaching up to 70% in renal cell carcinoma.

Despite a high incidence of adverse events (68.0% for the combination therapy), the toxicities were manageable and no unexpected safety issues were reported, indicating that the combination therapy is both effective and relatively safe.

Pembrolizumab is a monoclonal antibody that effectively blocks the PD-1 receptor on T cells, enhancing their ability to attack cancer cells, particularly in melanoma patients.

In a Phase I study involving 411 patients, pembrolizumab demonstrated high durable response rates with minimal toxicity, indicating its potential as a safe and effective treatment option for melanoma.

The ongoing KEYNOTE-495/KeyImPaCT study is evaluating the effectiveness of pembrolizumab combined with other therapies in advanced non-small cell lung cancer (NSCLC), with results showing varying objective response rates (ORR) based on tumor characteristics, ranging from 0-12% in low T-cell-inflamed groups to 50-60% in high T-cell-inflamed groups.

The study confirms that assessing T-cell-inflamed gene expression profiles (TcellinfGEP) and tumor mutational burden (TMB) can help identify which patients are more likely to benefit from pembrolizumab-based treatments, while the safety profiles of the combinations remain consistent with previous findings.
