lazertinib

16 active trials across 3 of our biomarkers, targeting EGFR. 5 active approvals for a biomarker on marked.bio.

Also known as YH25448, JNJ-73841937, Leclaza, Lazcluze.

Counts only trials that select patients by one of the biomarkers on marked.bio, not every trial of this drug.

Approvals and pivotal results

Biomarker-selected approvals in the United States and the European Union, with the pivotal trial's results and side effects where we have them. Results from different trials are not directly comparable.
