What is the mechanism of action of this treatment?

Pembrolizumab, an immune checkpoint inhibitor, works by targeting the PD-1 receptor on T-cells, thereby preventing cancer cells from evading immune detection and destruction. Lenvatinib, a tyrosine kinase inhibitor, blocks multiple pathways that promote tumor growth and angiogenesis. These mechanisms are significant for ovarian carcinoma patients as they offer a dual approach: enhancing the immune system's ability to target cancer cells and directly inhibiting tumor proliferation and blood supply, potentially leading to better treatment outcomes.

What side effects are associated with this type of intervention?

Common treatments for ovarian carcinoma, particularly those involving immune checkpoint inhibitors like Pembrolizumab and tyrosine kinase inhibitors like Lenvatinib, have several known side effects. Pembrolizumab can cause immune-related adverse events such as skin reactions, endocrine disorders, and pneumonitis. Lenvatinib is associated with hypertension, fatigue, diarrhea, and proteinuria. Combining these treatments may increase the risk of these side effects, necessitating careful monitoring and management by healthcare providers.

What prior FDA approvals exist?

The FDA has approved several treatments for ovarian carcinoma, including immune checkpoint inhibitors and tyrosine kinase inhibitors. Pembrolizumab, an immune checkpoint inhibitor targeting PD-1, has been approved for various cancers, including ovarian carcinoma, particularly in cases with high microsatellite instability (MSI-H) or mismatch repair deficiency (dMMR). Lenvatinib, a tyrosine kinase inhibitor, has been studied in combination with pembrolizumab for its efficacy in treating advanced solid tumors, including ovarian carcinoma. These approvals highlight the evolving landscape of targeted therapies in ovarian cancer treatment.

What other types of research exist?

Promising alternatives to Pembrolizumab and Lenvatinib for ovarian carcinoma patients include: 1) Nivolumab (another immune checkpoint inhibitor) which has shown efficacy in various cancers including non-small cell lung cancer and melanoma. 2) Atezolizumab (an anti-PD-L1 therapy) which has been effective in several cancers such as urothelial carcinoma and non-small cell lung cancer. 3) Bevacizumab (an anti-VEGF therapy) which is often used in combination with chemotherapy for ovarian cancer. 4) PARP inhibitors like Olaparib and Niraparib, which are particularly effective in patients with BRCA mutations or homologous recombination deficiency. These alternatives offer different mechanisms of action and may provide additional options for treatment.

Summary

This trial tests the combination of pembrolizumab and lenvatinib in patients with clear cell ovarian cancer that has returned or not responded to treatment. Pembrolizumab boosts the immune system to fight cancer, and lenvatinib blocks proteins that help cancer grow. These medications have been used together for various cancers, showing promising results.

Who is the study for?

This trial is for adults over 18 with recurrent or persistent clear cell ovarian cancer who've had at least one platinum-based chemotherapy. They must have measurable disease, stable health status (ECOG 0 or 1), adequate organ function, controlled blood pressure, and no major recent surgeries. Women of childbearing age need a negative pregnancy test and agree to use contraception.

What is being tested?

The study tests the combination of pembrolizumab and lenvatinib in treating clear cell ovarian cancer. It aims to determine how safe and effective this drug duo is when given together to patients who meet specific health criteria.

What are the potential side effects?

Potential side effects may include high blood pressure, fatigue, loss of appetite, thyroid dysfunction, nausea, mouth sores, rash or redness on hands/feet. More serious risks involve immune system reactions that could affect lungs or intestines.
