Rybrevant vs. Tagrisso

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Rybrevant (amivantamab) and Tagrisso (osimertinib) are both medications used to treat non-small cell lung cancer (NSCLC) with specific mutations in the epidermal growth factor receptor (EGFR) gene. However, they belong to different medication classes and have distinct characteristics. Rybrevant is a bispecific antibody that targets both EGFR and MET proteins, and it is administered intravenously. It is used in combination with other medications or alone, depending on the treatment stage. Common side effects include infusion-related reactions, rash, and skin infections. Tagrisso, on the other hand, is an oral EGFR inhibitor that specifically targets mutated EGFR proteins. It is taken once daily and is known for causing an acne-like rash and diarrhea. Tagrisso can be used as an initial treatment or when other EGFR inhibitors are no longer effective. Both medications are not recommended during pregnancy.
