What side effects are associated with this type of intervention?

Common treatments for brain tumors, such as MET receptor tyrosine kinase inhibitors like Tepotinib, often cause gastrointestinal issues (nausea, diarrhea), skin reactions (rash), and hematologic effects (neutropenia). When combined with other treatments like temozolomide, additional side effects can include myelosuppression, leading to thrombocytopenia and lymphopenia. Radiation therapy can further exacerbate these hematologic effects.

What prior FDA approvals exist?

FDA approvals for the treatment of brain tumors have included various targeted therapies and chemotherapeutic agents. While specific MET receptor tyrosine kinase inhibitors like tepotinib are still under investigation, other targeted therapies such as dabrafenib and trametinib have been approved for BRAF V600E-mutant gliomas. Additionally, temozolomide is a widely used chemotherapeutic agent for glioblastoma. Bevacizumab, an anti-angiogenic drug, has also been approved for recurrent glioblastoma. These treatments represent a range of approaches targeting specific genetic mutations and pathways involved in brain tumor growth.

What other types of research exist?

Promising alternatives to Tepotinib for brain tumor patients include: 1) Abemaciclib, which has shown efficacy in brain metastases from hormone receptor-positive breast cancer. 2) Tucatinib combined with Trastuzumab and Capecitabine, effective in HER2-positive breast cancer brain metastases. 3) Pembrolizumab, an immunotherapy showing promise in non-small cell lung cancer brain metastases. 4) Bevacizumab and Everolimus, which have been used in treating recurrent meningiomas. 5) Lapatinib combined with Capecitabine, effective in HER2-positive breast cancer brain metastases.

Summary

This trial tests tepotinib, a drug that targets specific genetic changes in cancer cells, in patients with brain tumors and certain genetic mutations. It includes those with brain metastases, glioblastoma, and specific types of lung cancer that have spread to the brain. Tepotinib works by blocking proteins that help cancer grow, aiming to slow or stop the disease.

Who is the study for?

This trial is for adults with brain tumors or metastases who have MET alterations. It includes those with glioblastoma, patients who've had prior cancer treatments, and NSCLC patients resistant to EGFR-TKI therapy with MET amplification. Participants must be in good physical condition, not pregnant or breastfeeding, willing to use birth control, and able to undergo lumbar puncture without medical risks.

What is being tested?

The study tests the drug tepotinib alone or combined with osimertinib in people with brain tumors due to MET gene changes. The first phase determines safe dosages while the second expands testing at these doses. Some participants will also undergo surgery as part of their treatment evaluation.

What are the potential side effects?

Potential side effects include reactions related to immune system activation such as inflammation in various organs, infusion-related responses (like fever or chills), fatigue, digestive issues like nausea or diarrhea, blood cell count changes which can affect immunity and healing capacity.

Other Research

Common treatments for brain tumors, such as glioblastomas and brain metastases, often target specific molecular pathways involved in tumor growth and survival. Tepotinib, a MET receptor tyrosine kinase inhibitor, works by blocking the MET signaling pathway, which is often altered in brain tumors and contributes to tumor growth and metastasis. Other treatments, like temozolomide, an alkylating agent, damage the DNA of cancer cells, leading to cell death. Targeted therapies, such as osimertinib for EGFR-mutated tumors, inhibit specific proteins involved in tumor cell proliferation. These mechanisms are crucial for brain tumor patients as they offer more personalized and potentially effective treatment options, targeting the specific genetic and molecular abnormalities driving their cancer.
