What side effects are associated with this type of intervention?

Common treatments for Non-Small Cell Lung Cancer (NSCLC), particularly EGFR Tyrosine Kinase Inhibitors (TKIs) like Osimertinib, often cause side effects such as diarrhea, rash, dry skin, and nail toxicity. Other EGFR TKIs, such as erlotinib and gefitinib, share similar side effects. Additionally, immune checkpoint inhibitors like pembrolizumab can lead to fatigue, nausea, and increased liver function tests. Chemotherapy agents, frequently used in combination with these targeted therapies, may result in neutropenia, anemia, and gastrointestinal disturbances.

What prior FDA approvals exist?

Osimertinib is an FDA-approved EGFR Tyrosine Kinase Inhibitor (TKI) used for the treatment of NSCLC with specific EGFR mutations. Other FDA-approved EGFR TKIs for NSCLC include Erlotinib and Afatinib, which target EGFR mutations to inhibit cancer cell growth. Additionally, Sotorasib and Adagrasib are approved for NSCLC with KRAS G12C mutations. Immunotherapies such as Pembrolizumab and Nivolumab, often combined with chemotherapy, are also approved for various subtypes of NSCLC, providing a broader range of treatment options.

What other types of research exist?

Currently, osimertinib remains the best first-line treatment for NSCLC patients with EGFR mutations. EGFR-TKI plus chemotherapy combination therapies are being investigated but are not yet established as standard alternatives.

Summary

This trial is testing osimertinib alone and with precise radiation therapy in patients with a specific type of lung cancer that has spread to the brain. Osimertinib blocks a protein that helps cancer grow, while the radiation therapy targets brain tumors with focused radiation.

Who is the study for?

This trial is for adults with a specific lung cancer (NSCLC) that has spread to the brain, who have not had prior treatment and whose cancer cells show certain mutations (EGFR). Participants must be in stable condition, able to follow study procedures, and willing to use effective contraception. Those with other active cancers, severe brain symptoms, or conditions affecting study participation are excluded.

What is being tested?

The study compares two approaches: one group receives Osimertinib alone while the other gets Osimertinib plus Stereotactic RadioSurgery (SRS), which is a precise radiation therapy. This phase II trial aims to determine if adding SRS improves outcomes for patients with brain metastases from NSCLC.

What are the potential side effects?

Osimertinib may cause diarrhea, rash, dry skin, nail changes and mouth sores. Rarely it can affect heart rhythm or cause lung problems. SRS might lead to headaches or fatigue shortly after treatment; long-term effects include potential memory issues.

Other Research

The most common treatments for Non-Small Cell Lung Cancer (NSCLC) include EGFR Tyrosine Kinase Inhibitors (TKIs) like Osimertinib, chemotherapy, and immunotherapy. Osimertinib targets and inhibits the epidermal growth factor receptor (EGFR) tyrosine kinase, which is often mutated in NSCLC, thereby blocking the signaling pathways that promote cancer cell growth and survival. Chemotherapy works by killing rapidly dividing cells, including cancer cells, but can also affect normal cells, leading to side effects. Immunotherapy, such as pembrolizumab, enhances the body's immune response against cancer cells by targeting immune checkpoints. These treatments are crucial for NSCLC patients as they offer targeted and systemic approaches to control and potentially eradicate the cancer, improving survival rates and quality of life.
