  • Remove the appropriate strength TECVAYLI vial(s) from refrigerated storage (2°C to 8°C [36°F to 46°F]).1
  • Once removed from refrigerated storage, equilibrate TECVAYLI to ambient temperature (15°C to 30°C [59°F to 86°F]), for at least 15 minutes. Do not warm TECVAYLI in any other way.1
  • Gently swirl the vial for approximately 10 seconds to mix. Do not shake.1
  • Withdraw the required injection volume of TECVAYLI from the vial(s) into an appropriately sized syringe using a transfer needle.1
  • Each injection volume should not exceed 2 mL. Divide doses that require greater than
    2 mL equally into multiple syringes.1
  • Use TECVAYLI with stainless steel injection needles and polypropylene or polycarbonate syringe material.1
  • Replace the transfer needle with an appropriately sized needle for injection.1

Administration of TECVAYLI

  • Inject the required volume of TECVAYLI into the subcutaneous tissue of the abdomen (preferred injection site). Alternatively, TECVAYLI may be injected into the subcutaneous tissue at other sites (eg, thigh). If multiple injections are needed, administer injections at least 2 cm apart.1
  • Do not inject into tattoos or scars or areas where the skin is red, bruised, tender, hard or not intact.1

Storage and Disposal

  • If the prepared dosing syringe(s) of TECVAYLI is not used immediately, store syringe(s) at 2°C to 8°C (36°F to 46°F) or at ambient temperature 15°C to 30°C (59°F to 86°F) for a maximum of 20 hours. Discard syringe(s) after 20 hours, if not used.1
  • Dispose of any unused product or waste material in accordance with local requirements.1 

Monitoring

  • Due to the risk of CRS and neurologic toxicity, including ICANS, patients should be hospitalized for 48 hours after administration of both step-up dose 1 and step-up dose 2. Instruct patients to remain within proximity of a healthcare facility and monitor them daily for 48 hours after the first treatment dose within the TECVAYLI step-up dosing schedule.1
