Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Summary

This study tests an experimental oral drug called WSD0922-FU in 40 adults with advanced non-small cell lung cancer that has a specific mutation (C797S) and has stopped responding to the standard treatment osimertinib. The main goal is to see if the drug can shrink tumors. It is an early-stage trial, so success is not guaranteed.

What this could mean

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

Active substance
WSD0922-FU (an oral drug targeting a specific lung cancer mutation)
What this could lead to
If it works, this could offer a new treatment option for people with a specific type of lung cancer that has stopped responding to current therapy.
What could go wrong
This is an early Phase 2 trial with only 40 participants, so results may not apply to everyone. The drug may not shrink tumors or could cause side effects.

This is an AI summary of the original study and may miss details. Read our disclaimer.
