More time without disease worsening

RYBREVANT® + LAZCLUZE™ is the only chemotherapy-free treatment proven to reduce the risk of cancer growing or spreading by 30% compared with the current standard of care (osimertinib)

At 23.7 months, half of the people receiving RYBREVANT® + LAZCLUZE™ lived without their cancer growing or spreading, compared with
16.6 months for osimertinib alone.

About the clinical trial

These results are from a clinical trial where 858 people with advanced NSCLC with exon 19 deletions or exon 21 L858R received a first treatment of RYBREVANT® in combination with LAZCLUZE™ or a first treatment of osimertinib alone. The main goal of the clinical trial was to measure how long people were on treatment before their cancer started growing or spreading. A secondary goal of the clinical trial was to measure how long people in the study lived.

Live longer

RYBREVANT® + LAZCLUZE™ is the first and only treatment proven to reduce the risk of death by 25% compared with osimertinib alone

Median overall survival is the amount of time after a study starts when half of the people are still alive.

After approximately 3 years of follow up, median overall survival for RYBREVANT® + LAZCLUZE™ had not been reached. Median overall survival for patients taking osimertinib was reached at 36.7 months.

*Mutations include exon 19 deletion or exon 21 L858R substitution mutations.
