Withhold or discontinue RYBREVANT as shown in Table 7. Refer to prescribing information for carboplatin and pemetrexed for additional dosage modification information. 2.9 Preparation Dilute and prepare RYBREVANT for intravenous infusion before administration. Check that the RYBREVANT solution is colorless to pale yellow. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if discoloration or visible particles are present. Determine the dose required and number of RYBREVANT vials needed based on patient's baseline weight [see Dosage and Administration (2.3 , 2.4) ] . Each vial of RYBREVANT contains 350 mg of amivantamab-vmjw. Withdraw and then discard a volume of either 5% Dextrose Injection or 0.9% Sodium Chloride Injection from the 250 mL infusion bag equal to the volume of RYBREVANT to be added (i.e., discard 7 mL diluent from the infusion bag for each RYBREVANT vial). Only use infusion bags made of polyvinylchloride (PVC), polypropylene (PP), polyethylene (PE), or polyolefin blend (PP+PE). Withdraw 7 mL of RYBREVANT from each vial and add it to the infusion bag. The final volume in the infusion bag should be 250 mL. Discard any unused portion left in the vial. Gently invert the bag to mix the solution. Do not shake. Diluted solutions should be administered within 10 hours (including infusion time) at room temperature 15°C to 25°C (59°F to 77°F). 2.10 Administration Administer the diluted RYBREVANT solution [see Dosage and Administration (2.9) ] by intravenous infusion using an infusion set fitted with a flow regulator and with an in-line, sterile, non-pyrogenic, low protein-binding polyethersulfone (PES) filter (pore size 0.2 micrometer). Administration sets must be made of either polyurethane (PU), polybutadiene (PBD), PVC, PP, or PE. The administration set with filter, must be primed with either 5% Dextrose Injection or 0.9% Sodium Chloride Injection prior to the initiation of each RYBREVANT infusion. Do not infuse RYBREVANT concomitantly in the same intravenous line with other agents. RYBREVANT in Combination with Lazertinib or RYBREVANT as a Single Agent Administer RYBREVANT as a single agent infusion every 2 weeks intravenously until disease progression or unacceptable toxicity according to the infusion rates in Table 8. Administer RYBREVANT via a peripheral line on Week 1 and Week 2, to reduce the risk of infusion-related reactions during initial treatment [see Warnings and Precautions (5.1) ]. RYBREVANT may be administered via central line for subsequent weeks. For the initial infusion, prepare RYBREVANT as close to administration time as possible to allow for the possibility of extended infusion time in the event of an infusion-related reaction. When given in combination with lazertinib, administer RYBREVANT any time after lazertinib when given on the same day.
