CARVYKTI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the CARVYKTI REMS Program [see Warnings and Precautions (5.5)] .
CARVYKTI (ciltacabtagene autoleucel) is a B-cell maturation antigen (BCMA)-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adult patients with relapsed or refractory multiple myeloma, who have received at least 1 prior line of therapy, including a proteasome inhibitor and an immunomodulatory agent, and are refractory to lenalidomide.
For autologous use only. For intravenous use only.
Dose
CARVYKTI is provided as a single dose for infusion containing a suspension of chimeric antigen receptor (CAR)-positive viable T cells in one infusion bag.
The recommended dose range is 0.5–1.0×10 6CAR-positive viable T cells per kg of body weight, with a maximum dose of 1×10 8CAR-positive viable T cells per single infusion.
Administration
CARVYKTI is for autologous use only. The patient's identity must match the patient identifiers on the CARVYKTI cassette and infusion bag. Do not infuse CARVYKTI if the information on the patient-specific labels does not match the intended patient.
Preparing the Patient for CARVYKTI Infusion
Confirm availability of CARVYKTI prior to starting the lymphodepleting chemotherapy regimen.
Pretreatment
Administer the lymphodepleting chemotherapy regimen: cyclophosphamide 300 mg/m 2intravenously (IV) and fludarabine 30 mg/m 2IV daily for 3 days.
See the prescribing information of cyclophosphamide and fludarabine for information on dose adjustment in renal impairment.
Lymphodepleting regimen must be delayed if a patient has serious adverse reactions from preceding bridging therapies (including clinically significant active infection, cardiac toxicity, and pulmonary toxicity) or active graft versus host disease in patient with prior allogeneic stem cell transplant. Consider repeating lymphodepleting regimen if CARVYKTI dosing is delayed by more than 14 days and patient has recovered from toxicity of the first lymphodepleting regimen.
Administer CARVYKTI infusion 2 to 4 days after the completion of the lymphodepleting chemotherapy regimen.
CARVYKTI infusion should be delayed if a patient has any of the following conditions:
- Clinically significant active infection or inflammatory disorders.
- Grade ≥3 non-hematologic toxicities of cyclophosphamide and fludarabine conditioning, except for Grade 3 nausea, vomiting, diarrhea, or constipation. CARVYKTI infusion should be delayed until resolution of these events to Grade ≤1.
Premedication
Administer the following pre-infusion medications to all patients 30 – 60 minutes prior to CARVYKTI infusion:
- Antipyretics (oral or intravenous acetaminophen 650 to 1000 mg).
- Antihistamine (oral or intravenous diphenhydramine 25 to 50 mg or equivalent).
Avoid prophylactic use of systemic corticosteroids because their use may interfere with the activity of CARVYKTI.
Receipt of CARVYKTI
- All sites approved for infusion will support required storage conditions for vapor phase of liquid nitrogen.
- CARVYKTI is shipped directly to the cell laboratory or clinical pharmacy associated with the infusion center in the vapor phase of a liquid nitrogen shipper.
- Confirm the patient's identity with the patient identifiers on the shipper.
- If the patient is not expected to be ready for same-day administration, before the shipper expires, transfer CARVYKTI to onsite vapor phase of liquid nitrogen storage.
Preparation of CARVYKTI for Infusion
Do not thaw the product until it is ready to be used. Coordinate the timing of CARVYKTI thaw and infusion. Confirm the infusion time in advance and adjust the start time for thaw so that CARVYKTI is available for infusion when the patient is ready. Once thawed, the CARVYKTI infusion must be completed within 2.5 hours at room/ambient temperature (20°C to 25°C).
Prior to thawing the product, confirm that tocilizumab and emergency equipment are available prior to the infusion and during the recovery period.
- Confirm patient identity: Prior to CARVYKTI preparation, match the patient's identity with the patient identifiers on the CARVYKTI cassette. Do not remove the CARVYKTI infusion bag from the cassette if the information on the patient-specific label does not match the intended patient. Contact Janssen Biotech, Inc.at 1-800-526-7736if there are any discrepancies between the labels and the patient identifiers.
- Once patient identification is confirmed, remove the CARVYKTI product bag from the cassette and check that the patient information on the cassette label matches the patient information on the bag label.
- Inspect the product bag for any breaches of container integrity, such as breaks or cracks before and after thawing. Do not administer if the bag is compromised, and contact Janssen Biotech, Inc.at 1-800-526-7736.
- Place the infusion bag inside a sealable plastic bag (preferably sterile) prior to thawing.
- Thaw CARVYKTI at 37°C±2°C using either a water bath or dry thaw method until there is no visible ice in the infusion bag. Total time from start of thaw until completion of thawing should be no more than 15 minutes.
- Remove the infusion bag from the sealable plastic bag and wipe dry. Gently mix the contents of the bag to disperse clumps of cellular material. If visible cell clumps remain, continue to gently mix the contents of the bag. Small clumps of cellular material should disperse with gentle manual mixing. Do not pre-filter into a different container, wash, spin down, or resuspend CARVYKTI in new media prior to infusion.
- Do not re-freeze or refrigerate thawed product.
Administration
- For autologous infusion only.
- Do NOT use a leukocyte-depleting filter.
- Ensure that a minimum of two doses of tocilizumab and emergency equipment are available prior to infusion and during the recovery period.
- Central venous access may be utilized for the infusion of CARVYKTI and is encouraged in patients with poor peripheral access.
- Confirm the patient's identity with the patient identifiers on the infusion bag. Do not infuse CARVYKTI if the information on the patient-specific label does not match the intended patient.
- Prime the tubing of the infusion set with normal saline prior to infusion.
- Once thawed, administer the entire contents of the CARVYKTI bag by intravenous infusion within 2.5 hours using infusion sets fitted with an in-line filter.
- Gently mix the contents of the bag during CARVYKTI infusion to disperse cell clumps.
- After the entire content of the product bag is infused, flush the administration line, inclusive of the in-line filter, with normal saline with a volume equal or greater to the total hold up volume of the primary administration set used inclusive of the drip tube, to ensure that all product is delivered.
CARVYKTI contains human blood cells that are genetically modified with replication-incompetent, self-inactivating, lentiviral vector. Follow universal precautions and local biosafety guidelines for handling and disposal of CARVYKTI to avoid potential transmission of infectious diseases.
Monitoring After Infusion
Administer CARVYKTI at a REMS-certified healthcare facility.
Monitor patients at least daily for 10 days following CARVYKTI infusion at a certified healthcare facility for signs and symptoms of cytokine release syndrome (CRS) and neurologic toxicities. Monitor periodically for 4 weeks for signs and symptoms of delayed neurologic toxicity.
Instruct patients to remain within proximity of a certified healthcare facility for at least 4 weeks following infusion.
Instruct patients to refrain from driving or hazardous activities for at least 8 weeks following infusion.
Management of Severe Adverse Reactions
Cytokine Release Syndrome (CRS)
Identify CRS based on clinical presentation [see Warnings and Precautions (5.2)] . Evaluate for and treat other causes of fever, hypoxia and hypotension. Consider laboratory testing to monitor for disseminated intravascular coagulation, hematology parameters, as well as pulmonary, cardiac, renal, and hepatic function. If CRS is suspected, manage according to the recommendations in Table 1.
Patients who experience CRS should be closely monitored for cardiac and other organ function until resolution of symptoms. Consider anti-seizure prophylaxis with levetiracetam in patients who experience CRS.
Patients who experience Grade 2 or higher CRS (e.g., hypotension not responsive to fluids, or hypoxia requiring supplemental oxygenation) should be monitored with continuous telemetry and pulse oximetry.
For severe or life-threatening CRS, consider intensive care unit level monitoring and supportive therapy.
For CRS refractory to first line interventions such as tocilizumab or tocilizumab and corticosteroids, consider alternate treatment options (i.e., higher corticosteroid dose, alternative anti-cytokine agents, e.g., anti-IL1 and/or anti-TNFα, anti-T cell therapies). Refractory CRS is characterized by fevers, end-organ toxicity (e.g., hypoxia, hypotension) not improving within 12 hours of first line interventions or development of HLH/MAS.
If concurrent neurologic toxicity is suspected during CRS, administer:
- Corticosteroids according to the more aggressive intervention based on the CRS and neurologic toxicity grades in Tables 1 and 2
- Tocilizumab according to the CRS grade in Table 1
- Anti-seizure medication according to the neurologic toxicity in Table 2

CARVYKTI is a cell suspension for intravenous infusion.
A single dose of CARVYKTI contains a cell suspension of 0.5–1.0×10 6CAR-positive viable T cells per kg body weight in one infusion bag up to a maximum of 1×10 8CAR-positive viable T cells [see How Supplied/Storage and Handling (16)] .
Pregnancy
Risk Summary
There are no available data on the use of CARVYKTI in pregnant women. No reproductive and developmental toxicity studies in animals have been conducted with CARVYKTI to assess whether it can cause fetal harm when administered to a pregnant woman. It is not known whether CARVYKTI has the potential to be transferred to the fetus and cause fetal toxicity. Based on the mechanism of action, if the transduced cells cross the placenta, they may cause fetal toxicity, including B-cell lymphocytopenia and hypogammaglobulinemia. Therefore, CARVYKTI is not recommended for women who are pregnant, or for women of childbearing potential not using contraception. Pregnant women should be advised that there may be risks to the fetus. Pregnancy after CARVYKTI therapy should be discussed with the treating physician.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%–4% and 15%–20%, respectively.
Lactation
Risk Summary
There is no information regarding the presence of CARVYKTI in human milk, the effect on the breastfed infant, and the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for CARVYKTI and any potential adverse effects on the breastfed infant from CARVYKTI or from the underlying maternal condition.
Females and Males of Reproductive Potential
Pregnancy Testing
Pregnancy status for females of child-bearing age should be verified prior to starting treatment with CARVYKTI.
Contraception
There are insufficient data to provide a recommendation concerning duration of contraception following treatment with CARVYKTI.
In clinical trials, female patients of childbearing potential were advised to practice a highly effective method of contraception and male patients with partners of childbearing potential or whose partners were pregnant were instructed to use a barrier method of contraception, until one year after the patient has received CARVYKTI infusion.
See the prescribing information for lymphodepleting chemotherapy for information on the need for contraception in patients who receive the lymphodepleting chemotherapy.
Infertility
There are no data on the effect of CARVYKTI on fertility.
Pediatric Use
Safety and effectiveness of CARVYKTI in pediatric patients have not been established.
Geriatric Use
Of the 97 patients in CARTITUDE-1 that received CARVYKTI, 28% were 65 to 75 years of age, and 8% were 75 years of age or older. CARTITUDE-1 did not include sufficient numbers of patients aged 65 and older to determine whether the effectiveness differs compared with that of younger patients. In 62 patients less than 65 years of age, all grade and Grade 3 and higher neurologic toxicities occurred in 19% (12/62) and 6% (4/62), respectively. Of the 35 patients ≥65 years of age, all grade and Grade 3 and higher neurologic toxicities occurred in 37% (13/35) and 20% (7/35), respectively.
Of the 188 patients in CARTITUDE-4 that received CARVYKTI, 38% were 65 to 75 years of age, and 2% were 75 years of age or older. In 112 patients less than 65 years of age, all grade and Grade 3 and higher neurologic toxicities occurred in 16% (18/112) and 3% (3/112) respectively. Of the 76 patients ≥65 years of age, all grade and Grade 3 and higher neurologic toxicities occurred in 34% (26/76) and 7% (5/76) respectively.
None.
