Renal Dose Adjustments

No adjustment recommended for any stage of renal impairment.

Liver Dose Adjustments

Liver enzymes should be monitored and dosing should be adjusted if needed.

Dose Adjustments

If the dose of one drug in the regimen is delayed, interrupted, or discontinued, the treatment with the other drugs may continue as scheduled; however, if dexamethasone is delayed or discontinued, the decision on whether to administer elotuzumab should be based on clinical judgment (i.e., risk of hypersensitivity).

If a Grade 2 or higher infusion reaction occurs, interrupt the infusion and institute appropriate medical measures. Upon resolution to Grade 1 or lower, restart elotuzumab at 0.5 mL per minute and gradually increase at a rate of 0.5 mL per minute every 30 minutes as tolerated to the rate at which the infusion reaction occurred. Resume the escalation regimen if there is no recurrence of the infusion reaction. Vital signs should be monitored every 30 minutes during and for 2 hours after the end of the infusion in patients who experience an infusion reaction. If the reaction recurs, stop the infusion and do not restart on that day. Severe infusion reactions may require permanent discontinuation of therapy and emergency treatment. Dose delays and modifications for dexamethasone and lenalidomide should be performed as recommended in their manufacturer prescribing information.
