Hypotension not requiring vasopressors Administer premedication prior to next dose of LUNSUMIO VELO. and/or For the next dose of LUNSUMIO VELO, monitor more frequently and consider hospitalization. hypoxia requiring low-flow oxygen Low-flow oxygen defined as oxygen delivered at < 6 L/minute; high-flow oxygen defined as oxygen delivered at ≥ 6 L/minute. by nasal cannula or blow-by. Recurrent Grade 2 CRS Manage per Grade 3 CRS. Grade 3 Fever ≥ 100.4°F (38°C) with: Ensure CRS symptoms are resolved for at least 72 hours prior to the next dose of LUNSUMIO VELO. Hypotension requiring a vasopressor (with or without vasopressin) Administer premedication prior to next dose of LUNSUMIO VELO. and/or For the next dose of LUNSUMIO VELO, monitor more frequently and hospitalize for the next dose. hypoxia requiring high flow oxygen by nasal cannula, face mask, non-rebreather mask, or Venturi mask. If CRS occurred after the 5 mg or 45 mg dose, administer 5 mg as the next dose. Resume treatment schedule after recovery. If the 5 mg dose is tolerated without grade 3 CRS, resume subsequent doses at 45 mg. Recurrent Grade 3 CRS Permanently discontinue LUNSUMIO VELO. Manage CRS per current practice guidelines and provide supportive therapy, which may include intensive care. Grade 4 Fever ≥ 100.4°F (38°C) with: Permanently discontinue LUNSUMIO VELO. Manage CRS per current practice guidelines and provide supportive therapy, which may include intensive care. Hypotension requiring multiple vasopressors (excluding vasopressin) and/or hypoxia requiring oxygen by positive pressure (e.g., CPAP, BiPAP, intubation and mechanical ventilation). Dosage Modifications for Neurologic Toxicity, including ICANS Management recommendations for neurologic toxicity, including ICANS, are summarized in Table 5 . At the first sign of neurologic toxicity, including ICANS, consider neurology evaluation and withholding of LUNSUMIO VELO based on the type and severity of neurotoxicity. Rule out other causes of neurologic symptoms. Provide supportive therapy, which may include intensive care. Table 5. Recommendations for Management of Neurologic Toxicity (including ICANS) Adverse Reaction Severity Based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.0. , Based on American Society for Transplantation and Cellular Therapy (ASTCT) 2019 grading for ICANS. Actions Neurologic Toxicity (including ICANS ) Grade 1 Continue LUNSUMIO VELO and monitor neurologic toxicity symptoms. If ICANS, manage per current practice guidelines. Grade 2 Withhold LUNSUMIO VELO until neurologic toxicity symptoms improve to Grade 1 or baseline for at least 72 hours. See Table 2 for recommendations on restarting LUNSUMIO VELO after dose delays [see Dosage and Administration (2.2) ] . Provide supportive therapy, and consider neurologic evaluation. If ICANS, manage per current practice guidelines. Grade 3 Withhold LUNSUMIO VELO until neurologic toxicity symptoms improve to Grade 1 or baseline for at least 72 hours. Provide supportive therapy, which may include intensive care, and consider neurology evaluation. If ICANS, manage per current practice guidelines. If recurrence of ICANS, permanently discontinue LUNSUMIO VELO. Grade 4 Permanently discontinue LUNSUMIO VELO. Provide supportive therapy, which may include intensive care, and consider neurology evaluation. If ICANS, manage per current practice guidelines. Other Adverse Reactions Table 6. Recommended Dosage Modification for Other Adverse Reactions Adverse Reactions Based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.0. Severity Actions Infections [see Warnings and Precautions (5.3) ] Grades 1 – 4 Withhold LUNSUMIO VELO in patients with active infection until the infection resolves. See Table 2 for recommendations on restarting LUNSUMIO VELO after dose delays [see Dosage and Administration (2.2) ] . For Grade 4, consider permanent discontinuation of LUNSUMIO VELO. Neutropenia [see Warnings and Precautions (5.4) ] Absolute neutrophil count less than 0.5 × 10 9 /L Withhold LUNSUMIO VELO until absolute neutrophil count is 0.5 × 10 9 /L or higher. Other Adverse Reactions [see Warnings and Precautions (5.5) and Adverse Reactions (6.1) ] Grade 3 or higher Withhold LUNSUMIO VELO until the toxicity resolves to Grade 1 or baseline. Permanently discontinue LUNSUMIO VELO if a Grade 4 injection site reaction occurs. 2.5 Preparation and Administration If the LUNSUMIO VELO dose is not administered immediately, refer to "Storage of Prepared Syringe" section below. To prevent medication errors, check the vial labels to ensure that the drug being prepared and administered is LUNSUMIO VELO for subcutaneous administration. A peel-off label is provided on the LUNSUMIO VELO Prescribing Information that should be attached to the final prepared syringe. Remove the peel-off label from the Prescribing Information in the LUNSUMIO VELO carton before discarding the carton. Affix the peel-off label to the prepared LUNSUMIO VELO syringe. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if the solution is discolored, or cloudy, or if foreign particles are present. Each LUNSUMIO VELO 5 mg/0.5 mL and 45 mg/mL vial are supplied as ready-to-use solution that do not need dilution prior to subcutaneous administration. LUNSUMIO VELO vials are for one-time use in one patient only. No incompatibilities between LUNSUMIO VELO and polypropylene or polycarbonate syringe material, stainless-steel transfer and injection needles, and polyethylene or polypropylene syringe closing caps have been observed. Preparation of the Syringe Use aseptic technique to prepare LUNSUMIO VELO. Select the appropriate strength vial based on the prescribed dose. Withdraw the required volume of LUNSUMIO VELO solution from the vial with a syringe and an appropriately sized transfer needle (18G to 21G recommended). The smallest syringe that can accurately deliver the injection volume should be used. Discard any unused portion left in the vial. Remove the transfer needle and attach an appropriately sized injection needle (25G to 30G recommended). Apply peel-off label from the Prescribing Information to the prepared drug product. Once transferred from the vial to the syringe, LUNSUMIO VELO solution for injection should be injected immediately because LUNSUMIO VELO solution for injection does not contain any antimicrobial-preservative. Administration Inject the required volume of LUNSUMIO VELO into the subcutaneous tissue of the abdomen or thigh, changing the site of injection with each dose. Do not inject into tattoos, moles, scars or areas where the skin is red, bruised, tender, hard, or not intact. The dose should be administered subcutaneously over approximately 30 seconds to 1 minute. Storage of Prepared Syringe The prepared syringe should be used immediately. If not used immediately, replace the transfer needle with a syringe closing cap. Do not attach an injection needle. The capped syringe can be stored refrigerated at 2°C to 8°C (36°F to 46°F) for up to 32 hours protected from light and/or at 9°C to 25°C (37°F to 77°F) for up to 8 hours at ambient light. Once removed from refrigerated storage, the solution can be equilibrated to ambient temperature up to 25°C (77°F) prior to administration. Do not warm LUNSUMIO VELO in any other way.
