What is Rybrevant?

Rybrevant is a prescription medicine used to treat adults with non-small cell lung cancer (NSCLC) that has spread to other parts of the body (metastatic) or cannot be removed by surgery, and has a certain abnormal epidermal growth factor receptor “EGFR” gene(s) and whose disease has worsened while on or after chemotherapy that contains platinum.

Your healthcare provider will perform a test to make sure that Rybrevant is right for you.
It is not known if Rybrevant is safe and effective in children.


Amivantamab-vmjw is a low-fucose human immunoglobulin G1-based bispecific antibody directed against the EGF and MET receptors, produced by mammalian cell line (Chinese Hamster Ovary [CHO]) using recombinant DNA technology that has a molecular weight of approximately 148 kDa. RYBREVANT (amivantamab-vmjw) injection for intravenous infusion is a sterile, preservative-free, colorless to pale yellow solution in single-dose vials. The pH is 5.7.

Each RYBREVANT vial contains 350 mg (50 mg/mL) amivantamab-vmjw, EDTA disodium salt dihydrate (0.14 mg), L-histidine (2.3 mg), L-histidine hydrochloride monohydrate (8.6 mg), L-methionine (7 mg), polysorbate 80 (4.2 mg), sucrose (595 mg), and water for injection, USP.

 Mechanism of Action

Amivantamab-vmjw is a bispecific antibody that binds to the extracellular domains of EGFR and MET.

In in vitro and in vivo studies amivantamab-vmjw was able to disrupt EGFR and MET signaling functions through blocking ligand binding and, in exon 20 insertion mutation models, degradation of EGFR and MET. The presence of EGFR and MET on the surface of tumor cells also allows for targeting of these cells for destruction by immune effector cells, such as natural killer cells and macrophages, through antibody-dependent cellular cytotoxicity (ADCC) and trogocytosis mechanisms, respectively.
