1 INDICATIONS AND USAGE RYBREVANT is a bispecific EGF receptor-directed and MET receptor-directed antibody indicated: in combination with lazertinib for the first-line treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 L858R substitution mutations, as detected by an FDA-approved test. ( 1 , 2.2 ) in combination with carboplatin and pemetrexed for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions or exon 21 L858R substitution mutations, whose disease has progressed on or after treatment with an EGFR tyrosine kinase inhibitor.

6 ADVERSE REACTIONS The following adverse reactions are discussed elsewhere in the labeling: Infusion-Related Reactions [see Warnings and Precautions (5.1) ] Interstitial Lung Disease/Pneumonitis [see Warnings and Precautions (5.2) ] Venous Thromboembolic Events [see Warnings and Precautions (5.3) ] Dermatologic Adverse Reactions [see Warnings and Precautions (5.4) ] Ocular Toxicity [see Warnings and Precautions (5.5) ] RYBREVANT in Combination with Lazertinib The most common adverse reactions (≥ 20%) were rash, nail toxicity, infusion-related reaction, musculoskeletal pain, stomatitis, edema, VTE, paresthesia, fatigue, diarrhea, constipation, COVID-19, hemorrhage, dry skin, decreased appetite, pruritus, and nausea.

8.1 Pregnancy Risk Summary Based on the mechanism of action and findings in animal models, RYBREVANT can cause fetal harm when administered to a pregnant woman. There are no available data on the use of RYBREVANT in pregnant women or animal data to assess the risk of RYBREVANT in pregnancy. Disruption or depletion of EGFR in animal models resulted in impairment of embryo-fetal development including effects on placental, lung, cardiac, skin, and neural development. The absence of EGFR or MET signaling has resulted in embryo lethality, malformations, and post-natal death in animals (see Data ).

5 WARNINGS AND PRECAUTIONS Infusion-Related Reactions (IRR) : Interrupt infusion at the first sign of IRRs. Reduce the infusion rate or permanently discontinue RYBREVANT based on severity. ( 2.5 , 2.8 , 5.1 ) Interstitial Lung Disease (ILD)/Pneumonitis : Monitor for new or worsening symptoms indicative of ILD. Immediately withhold RYBREVANT in patients with suspected ILD/pneumonitis and permanently discontinue if ILD/pneumonitis is confirmed. ( 2.8 , 5.2 ) Venous Thromboembolic (VTE) Events with Concomitant Use with Lazertinib: Prophylactic anticoagulation is recommended for the first four months of treatment. Monitor for signs and symptoms of VTE and treat as medically appropriate. Withhold RYBREVANT and lazertinib based on severity. 4 CONTRAINDICATIONS None. None. ( 4 )
