DATROWAY is an FDA-registered drug product whose active ingredient is DATOPOTAMAB DERUXTECAN. It is labelled by Daiichi Sankyo Inc. taken by intravenous and marketed as a human prescription drug product. Identifiers on file: NDC 65597-801, application BLA761394, label effective 20260527. This page reproduces the FDA-approved label text so you can check what a product is, who makes it and how it is supplied before discussing it with a pharmacist or prescriber.

Across FDA labelling, products containing DATOPOTAMAB DERUXTECAN are most often described in connection with: unresectable metastatic, adult patients, breast cancer, epidermal growth, factor receptor, received prior, see clinical, ihc ihc. Wording differs between labels, and the full indications section on this page takes precedence when it is present.

DATROWAY (datopotamab deruxtecan-dlnk) is a hazardous drug. Follow applicable special handling and disposal procedures. 1 Reconstitution Reconstitute immediately before dilution. More than one vial may be needed for a full dose. Calculate the dose (mg), the total volume of reconstituted DATROWAY solution required, and the number of vial(s) of DATROWAY needed [see Dosage and Administration (2.2) ]. Reconstitute each 100 mg vial using a sterile syringe to slowly inject 5 mL of Sterile Water for Injection into each vial to obtain a final concentration of 20 mg/mL. Swirl the vial gently until completely dissolved. Do not shake. If not used immediately, refrigerate the reconstituted DATROWAY solution in the original vial at 2°C to 8°C (36°F to 46°F) for up to 48 hours from the time of reconstitution. Protect the vial from light. Do not freeze. The product does not contain a preservative. Discard unused reconstituted DATROWAY after 48 hours of refrigeration. Dilution Withdraw the calculated amount from the vial(s) using a sterile syringe. Inspect for particulate matter and discoloration prior to administration. The reconstituted solution should be clear and colorless to light yellow. Do not use if visible particles are observed or if the solution is cloudy or discolored. Dilute the calculated volume of reconstituted DATROWAY in an infusion bag containing 100 mL of 5% Dextrose Injection. DO NOT use Sodium Chloride Injection. DATROWAY is compatible with an infusion bag made of polyvinylchloride or polyolefin (polypropylene or copolymer of ethylene and propylene). Gently invert the infusion bag to thoroughly mix the solution. Do not shake. Cover the infusion bag to protect from light. If not used immediately, store at room temperature at up to 25°C (77°F) for up to 4 hours including preparation or in a refrigerator at 2°C to 8°C (36°F to 46°F) for up to 24 hours. Do not freeze. Discard any unused portion left in the vial. Administration The maximum time from reconstitution of the vial through the end of administration should not exceed 48 hours. Discard if storage time exceeds these limits. If the prepared infusion solution was stored refrigerated at 2°C to 8°C (36°F to 46°F), allow the solution to reach room temperature prior to administration, protected from light. Inspect for particulate matter and discoloration prior to administration. Administer DATROWAY as an intravenous infusion only with an infusion line and tubing set made of polyvinyl chloride, polybutadiene or low-density polyethylene. Administer DATROWAY with a 0.2-micron in-line polytetrafluoroethylene, polyethersulfone or nylon 66 filter. Do NOT administer as an intravenous push or bolus. Cover the infusion bag to protect from light during administration. Do not mix DATROWAY with other drugs or administer other drugs through the same intravenous line. Instruct the patient to hold ice chips or ice water in the mouth throughout the infusion of DATROWAY. First infusion: Administer infusion over 90 minutes. Observe patients during the infusion and for at least 1 hour following the initial dose for signs or symptoms of infusion-related reactions. Second Infusion: If first infusion was tolerated, administer second infusion over 30 minutes. Observe patients during the infusion and for at least 1 hour after infusion. Subsequent Infusions: Administer infusion over 30 minutes if prior infusions were tolerated. Observe patients during the infusion and for at least 30 min after infusion.
