What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of two targeted therapies, Osimertinib and Selumetinib, to determine their effectiveness in treating Non-Small Cell Lung Cancer (NSCLC) with an EGFR mutation. These drugs target specific genetic changes in the cancer to block cancer cell growth. Individuals with stage IV NSCLC with certain EGFR mutations who have not yet received treatments like chemotherapy or targeted therapies may be suitable candidates for this trial. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

The trial requires that you stop taking medications that are potent inhibitors or inducers of CYP3A4, as well as high doses of supplemental vitamin E. If you are on these medications, you will need to follow specific washout times before participating.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that most people tolerate the combination of osimertinib and selumetinib well. One study found that most participants experienced only mild to moderate side effects, such as skin issues and other manageable symptoms. This suggests the combination usually doesn't cause serious problems for most people.

Osimertinib is already approved for treating certain types of lung cancer, indicating its general safety. Adding selumetinib aims to enhance treatment effects, and current evidence suggests this combination could be a promising option without major safety concerns. However, like any treatment, some risk of side effects exists. Discuss any concerns with a healthcare provider. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Osimertinib and Selumetinib for lung cancer because they target cancer cells in a unique way. Unlike standard treatments like chemotherapy, which attack rapidly dividing cells indiscriminately, Osimertinib is designed to specifically target and inhibit a mutated protein called EGFR, commonly found in lung cancer. Selumetinib, on the other hand, inhibits a pathway called MEK, potentially overcoming resistance to other treatments. This combination approach allows for a more precise attack on cancer cells, potentially leading to better outcomes and fewer side effects for patients.

What evidence suggests that this combination treatment could be effective for lung cancer?

Research has shown that osimertinib is an effective treatment for non-small cell lung cancer (NSCLC) with an EGFR mutation. Studies have found that patients taking osimertinib live for about 24.8 months on average and experience about 11.9 months before their cancer progresses. This trial examines the combination of osimertinib with another drug, selumetinib, to enhance treatment effectiveness. Early results suggest this combination might be effective because selumetinib targets a different aspect of cancer growth. This approach aims to improve outcomes for people with EGFR-mutant NSCLC by attacking the cancer more comprehensively. ^{6 7 8 9 10}

Published Research Related to This Trial

In a retrospective analysis of 32 patients with EGFR T790M-mutant non-small-cell lung cancer, osimertinib showed a 50% objective response rate and a median progression-free survival of 11.3 months, indicating its efficacy in clinical practice.

The median overall survival was 18.3 months, with better outcomes observed in patients without cerebral metastases and those with better performance status, highlighting the importance of these factors in treatment response.

Osimertinib, an irreversible tyrosine kinase inhibitor, showed excellent activity in treating a 69-year-old man with metastatic EGFR-mutated non-small cell lung cancer, leading to a rapid treatment response despite initial severe pancytopenia.

After experiencing pancytopenia, the patient's dose of osimertinib was reduced from 80 mg to 40 mg daily, which allowed for continued effective treatment without further adverse events, demonstrating the potential for safe dose adjustments.
