Lisocabtagene Maraleucel Dosage

Usual Adult Dose for Lymphoma

PRETREATMENT:
-Administer the lymphodepleting chemotherapy regimen before infusion of this drug: fludarabine 30 mg/m2/day IV and cyclophosphamide 300 mg/m2/day IV for 3 days.
-See the prescribing information for fludarabine and cyclophosphamide for information on dose adjustment in renal impairment.
-Infuse this drug 2 to 7 days after completion of lymphodepleting chemotherapy.
-Delay the infusion of this drug if the patient has unresolved serious adverse events from preceding chemotherapies, active uncontrolled infection, or active graft-versus-host disease (GVHD).

PREMEDICATION:
-Premedicate the patient with acetaminophen (650 mg orally) and diphenhydramine (25 to 50 mg IV or orally), or another H1-antihistamine, 30 to 60 minutes prior to therapy with this drug.
-Avoid prophylactic use of systemic corticosteroids, as they may interfere with the activity of this drug.

A single dose of this drug contains 50 to 110 x 106 CAR-positive viable T cells (consisting of 1:1 CAR-positive viable T cells of the CD8 and CD4 components), with each component supplied separately in 1 to 4 single-dose vials. Each mL contains 1.5 x 10(6) to 70 x 10(6) CAR-positive viable T cells (3).See the respective Certificate of Release for Infusion (RFI Certificate) for each component, for the actual cell counts and volumes to be infused.

ADMINISTRATION:
-When this drug has been drawn into syringes, proceed with administration as soon as possible.
-The total time from removal from frozen storage to patient administration should not exceed 2 hours as indicated by the time entered on the syringe label.
STEPS:
1) Use IV normal saline to flush all the infusion tubing prior to and after each CD8 or CD4 component administration.
2) Administer the entire volume of the CD8 component IV at an infusion rate of approximately 0.5 mL/min, using the closest port or Y-arm. NOTE: The time for infusion will vary but will usually be less than 15 minutes for each component.
3) If more than one syringe is required for a full cell dose of the CD8 component, administer the volume in each syringe consecutively without any time between administering the contents of the syringes (unless there is a clinical reason [e.g., infusion reaction] to hold the dose).
4) After the CD8 component has been administered, flush the tubing with normal saline, using enough volume to clear the tubing and the length of the IV catheter. 5) Administer the CD4 component second, immediately after administration of the CD8 component is complete, using steps 1 through 4, as described for the CD8 component. Following administration of the CD4 component, flush the tubing with normal saline, using enough volume to clear the tubing and the length of the IV catheter.

Comments:
-Consult the manufacturer product information for preparation and administration.

If no improvement or continued rapid progression, maximize dexamethasone, switch to high-dose methylprednisolone 2 mg/kg if needed. After 2 doses of tocilizumab, consider alternative immunosuppressants. Do not exceed 3 doses tocilizumab in 24 hours, or 4 doses total.
-Corticosteroids (if corticosteroids are initiated, continue corticosteroids for at least 3 doses or until complete resolution of symptoms, and consider corticosteroid taper}: If no improvement within 24 hours or rapid progression, repeat tocilizumab and escalate dose and frequency of dexamethasone (10 to 20 mg IV every 6 to 12 hours). If no improvement or continued rapid progression, maximize dexamethasone, switch to high-dose methylprednisolone 2 mg/kg if needed. After 2 doses of tocilizumab, consider alternative immunosuppressants. Do not exceed 3 doses tocilizumab in 24 hours, or 4 doses in total. If no improvement within 24 hours or rapid progression, repeat tocilizumab and escalate dose and frequency of dexamethasone (10 to 20 mg IV every 6 to 12 hours). If no improvement or continued rapid progression, maximize dexamethasone, switch to high-dose methylprednisolone 2 mg/kg if needed. After 2 doses of tocilizumab, consider alternative immunosuppressants. Do not exceed 3 doses tocilizumab in 24 hours, or 4 doses total.
GRADE 3 (symptoms require and respond to aggressive intervention; oxygen requirement greater than or equal to 40% FiO2, or hypotension requiring high-dose or multiple vasopressors, or Grade 3 organ toxicity, or Grade 4 transaminitis):
-Per Grade 2: If no improvement within 24 hours or rapid progression of CRS, repeat tocilizumab and escalate dose and frequency of dexamethasone (10 to 20 mg IV every 6 to 12 hours). If no improvement or continued rapid progression, maximize dexamethasone, switch to high-dose methylprednisolone 2 mg/kg if needed. After 2 doses of tocilizumab, consider alternative immunosuppressants. Do not exceed 3 doses tocilizumab in 24 hours, or 4 doses total.
-Corticosteroids (if corticosteroids are initiated, continue corticosteroids for at least 3 doses or until complete resolution of symptoms, and consider corticosteroid taper}: Administer dexamethasone 20 mg IV every 12 hours.

NEUROLOGIC TOXICITY:
-Monitor patients for neurologic toxicities.
-Rule out other causes of neurologic symptoms.
-Provide intensive care supportive therapy for severe or life-threatening neurologic toxicities.
-If neurologic toxicity is suspected, manage according to the recommendations below.
-If concurrent CRS is suspected during neurologic toxicity, administer corticosteroids according to the more aggressive intervention based on the CRS and neurologic toxicity grades, tocilizumab, and antiseizure medication according to the neurologic toxicity outlined below:
-GRADE 1: Start non-sedating, antiseizure medicines (e.g., levetiracetam) for seizure prophylaxis. If 72 hours or more after infusion, observe. If less than 72 hours after infusion, consider dexamethasone 10 mg IV every 12 to 24 hours for 2 to 3 days.
-GRADE 2: Start non-sedating, antiseizure medicines (e.g., levetiracetam) for seizure prophylaxis. Dexamethasone 10 mg IV every 12 hours for 2 to 3 days, or longer for persistent symptoms. Consider taper for a total steroid exposure of greater than 3 days. If no improvement after 24 hours or worsening of neurologic toxicity, increase the dose and/or frequency of dexamethasone up to a maximum of 20 mg IV every 6 hours. If no improvement after another 24 hours, rapidly progressing symptoms, or life-threatening complications arise, give methylprednisolone (2 mg/kg loading dose, followed by 2 mg/kg divided 4 times a day; taper within 7 days).
-GRADE 3: Start non-sedating, antiseizure medicines (e.g., levetiracetam) for seizure prophylaxis. Dexamethasone 10 to 20 mg IV every 8 to 12 hours. Steroids are not recommended for isolated Grade 3 headaches. If no improvement after 24 hours or worsening of neurologic toxicity, escalate to methylprednisolone (dose and frequency as per Grade 2). If cerebral edema is suspected, consider hyperventilation and hyperosmolar therapy. Give high-dose methylprednisolone (1 g to 2 g, repeat every 24 hours if needed; taper as clinically indicated) and cyclophosphamide 1.5 g/m2.
-GRADE 4: Start non-sedating, antiseizure medicines (e.g., levetiracetam) for seizure prophylaxis. Dexamethasone 20 mg IV every 6 hours. If no improvement after 24 hours or worsening of neurologic toxicity, escalate to methylprednisolone (dose and frequency as per Grade 2). If cerebral edema is suspected, consider hyperventilation and hyperosmolar therapy. Give high-dose methylprednisolone (1 g to 2 g, repeat every 24 hours if needed; taper as clinically indicated), and cyclophosphamide 1.5 g/m2.
