What You Need to Know Before You Apply

What is the purpose of this trial?

This phase II trial studies how well pembrolizumab and sunitinib malate work in treating participants with thymic cancer that has spread to other places in the body or cannot be removed by surgery and does not respond to treatment. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and sunitinib malate may work better in treating thymic cancer.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications. However, you cannot use certain drugs that strongly affect liver enzymes (CYP3A4/5 inhibitors or inducers) within 10 days before starting the trial. It's best to discuss your current medications with the trial team.

Is the combination of Pembrolizumab and Sunitinib safe for treating thymic cancer?

Pembrolizumab has been used in treating thymic cancer, but it can cause severe immune-related side effects, especially in thymic epithelial tumors, so close monitoring is necessary. There is no specific safety data available for the combination of Pembrolizumab and Sunitinib in thymic cancer, but Pembrolizumab alone has shown both effectiveness and potential for serious side effects.12345

What makes the drug combination of Pembrolizumab and Sunitinib unique for treating thymic cancer?

The combination of Pembrolizumab and Sunitinib is unique for treating thymic cancer because Pembrolizumab is an immune checkpoint inhibitor that targets PD-1, showing promise in tumors with high PD-L1 expression, while Sunitinib is a multi-targeted tyrosine kinase inhibitor that has shown potential in various cancers, including thymic malignancies. This combination leverages both immune modulation and targeted cancer cell inhibition, offering a novel approach for a condition with limited treatment options.13678

What data supports the effectiveness of the drug Pembrolizumab for treating thymic cancer?

Research shows that Pembrolizumab, when used alone or with chemotherapy, has been effective in treating thymic cancer, especially in cases with high PD-L1 expression (a protein that helps cancer cells hide from the immune system). Some patients experienced significant tumor reduction and long-term remission, suggesting it could be a promising option for this aggressive cancer.12358

What Are the Treatments Tested in This Trial?

Interventions

  • Pembrolizumab
  • Sunitinib Malate
Trial Overview The study tests pembrolizumab (a monoclonal antibody) combined with sunitinib malate (an enzyme inhibitor) on participants with refractory metastatic or unresectable thymic cancer. It aims to see if this combination better inhibits tumor growth compared to current treatments.

Published Research Related to This Trial

The combination of pembrolizumab and chemotherapy as a first-line treatment for metastatic thymic carcinoma showed promising results in two cases, with one patient achieving a complete response lasting over 3 years and the other a partial response for 20 months.
This study highlights the potential of pembrolizumab combined with chemotherapy in treating advanced thymic carcinoma, suggesting it may be a viable treatment strategy that deserves further investigation.
Robust and durable response to first-line treatment of pembrolizumab combined with chemotherapy in two patients with metastatic thymic squamous cell carcinoma: Case report.Chen, C., Sun, P., Long, J.[2022]
In a phase II study of 33 patients with thymic epithelial tumors (TET) who had progressed after platinum-based chemotherapy, pembrolizumab demonstrated encouraging antitumor activity, with 28.6% of thymoma patients and 19.2% of thymic carcinoma patients achieving a partial response.
While pembrolizumab showed efficacy, it was associated with a significant incidence of immune-related adverse events, particularly in patients with thymoma, highlighting the need for further research to optimize treatment and minimize side effects.

A 68-year-old woman with advanced thymic carcinoma showed significant tumor reduction after receiving pembrolizumab, a PD-1 inhibitor, as a second-line treatment after chemotherapy failed.
The patient's tumor expressed 100% PD-L1, suggesting that high PD-L1 expression may indicate a better response to pembrolizumab in treating thymic carcinoma.
