Summary

This phase 2 study tested a combination of the targeted drug osimertinib (Tagrisso) plus standard chemotherapy as a first treatment for advanced non-small cell lung cancer with uncommon EGFR mutations. Only 4 participants were enrolled before the study was terminated, so no meaningful conclusions can be drawn. The goal was to see if the combination could shrink tumors and delay cancer progression.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

osimertinib (Tagrisso) plus platinum and pemetrexed chemotherapy

What this could lead to

If successful, this combination could offer a new first-line treatment option for people with advanced lung cancer that has rare EGFR mutations.

What could go wrong

This was a very small, early-phase study that was terminated early, so results are limited. The combination may not prove effective or safe in larger trials.
