Trial Summary

What is the purpose of this trial?

The reason for the study is to find out if an experimental combination of an oral medication called osimertinib (TAGRISSO®) when used in combination with chemotherapy is more effective than giving osimertinib alone for the treatment of locally advanced or metastatic non-small cell lung cancer. Some lung cancers are due to mutations in the Deoxyribonucleic acid (DNA) which, if known, can help physicians decide the best treatment for their patients. One type of mutation can occur in the gene that produces a protein on the surface of cells called the Epidermal Growth Factor Receptor (EGFR). Osimertinib is an Epidermal Growth Factor Receptor (EGFR) tyrosine kinase inhibitor (TKI) that targets Epidermal Growth Factor Receptor (EGFR) mutations. Unfortunately, despite the benefit observed for patients treated with osimertinib, the vast majority of cancers are expected to develop resistance to the drug over time. The exact reasons why resistance develops are not fully understood but based upon clinical research it is hoped that combining osimertinib with another type of anti-cancer therapy known as chemotherapy will delay the onset of resistance and the worsening of a patient's cancer. In total the study aims to enroll approximately 586 patients, consisting of approximately 30 patients who will participate in a safety run-in component of the trial, and approximately 556 who will receive osimertinib alone or osimertinib in combination with chemotherapy in the main trial. In the main part of the trial there is a one in two chance of receiving osimertinib alone, and the treatment is decided at random by a computer. The study involves a Screening Period, Treatment Period, and Follow up Period. Whilst receiving study medication, it is expected patients will attend, on average, approximately 15 visits over the first 12 months and then approximately 4 visits per year afterwards. Each visit will last about 2 to 6 hours depending on the arrangement of medical assessments by the study centre.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you are on any systemic anti-cancer therapy for advanced Non-Small Cell Lung Cancer, you may need to stop, as prior treatment with such therapies is an exclusion criterion.

What data supports the effectiveness of the drug Osimertinib in treating non-small cell lung cancer?

Osimertinib is effective in treating non-small cell lung cancer (NSCLC) with a specific mutation (EGFR T790M) that often causes resistance to earlier treatments. It has been shown to significantly prolong the time patients live without the cancer getting worse compared to older treatments. ^{1 2 3 4 5}

Is the combination of Osimertinib and chemotherapy safe for humans?

Osimertinib has been generally well tolerated in clinical trials for non-small cell lung cancer, with common side effects including diarrhea, rash, dry skin, and nail issues. Serious side effects occurred in 28% of patients, and 5.6% stopped treatment due to these effects. No new safety concerns were identified in recent studies. ^{1 3 6 7 8}

What makes the drug osimertinib unique for treating non-small cell lung cancer?

Osimertinib is unique because it is a third-generation drug that specifically targets the EGFR T790M mutation, which is often present in patients who have developed resistance to earlier treatments. It is taken orally and has shown effectiveness with fewer side effects compared to other treatments. ^{1 3 4 7 9}
