Data featured in a late-breaking oral presentation at the 2024 International Myeloma Society Annual Meeting
RIO DE JANEIRO, Sept. 27, 2024 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) announced today long-term results from the Phase 3 CARTITUDE-4 study that show a single infusion of CARVYKTIŽ (ciltacabtagene autoleucel) significantly extended overall survival (OS) in patients with relapsed or lenalidomide-refractory multiple myeloma who have received at least one prior line of therapy, including a proteasome inhibitor (PI), reducing the risk of death by 45 percent versus standard therapies of pomalidomide, bortezomib and dexamethasone (PVd) or daratumumab, pomalidomide and dexamethasone (DPd).1 With these data, CARVYKTIŽ is now the first and only cell therapy to improve OS versus standard therapies for patients with lenalidomide-refractory multiple myeloma as early as second line.1 Findings were featured as a late-breaking oral presentation at the 2024 International Myeloma Society (IMS) Annual Meeting (Abstract #OA-65).1

"The three-year follow-up data from the Phase 3 CARTITUDE-4 study show a statistically significant and clinically meaningful improvement in overall survival and quality-of-life measures with CARVYKTI versus standard therapiesmeaningful results that have the potential to transform the multiple myeloma treatment landscape," said Binod Dhakal, M.D., M.S., Associate Professor of Medicine at the Medical College of Wisconsin, Division of Hematology, and study investigator.* "This adds to the growing body of data reinforcing the promise of a single infusion of CARVYKTI, which, in addition to demonstrating a significant overall survival benefit, also offers patients the opportunity of a period free from multiple myeloma treatment as early as second line."
The Phase 3 CARTITUDE-4 study evaluated CARVYKTIŽ compared to standard therapies of PVd or DPd for the treatment of patients with relapsed or lenalidomide-refractory multiple myeloma after one prior line of therapy.1 Patients who received one to three prior lines of therapy, including a PI and immunomodulatory agent (IMiD), and were lenalidomide-refractory were randomized (CARVYKTIŽ [cilta-cel], n=208, standard therapies, n=211).1 At median follow-up of almost three years (34 months), median OS for patients treated with both CARVYKTIŽ or standard therapies was not reached (NR) (95 percent Confidence Interval [CI], not estimable (NE) NE) and (95 percent CI, 37.75 months NE) (Hazard Ratio [HR], 0.55; 95 percent CI, 0.39-0.79; P=0.0009).1 At 30-month follow-up, OS rates were 76 percent for patients on the CARVYKTIŽ arm and 64 percent for patients on the standard therapies arm.1 These data show CARVYKTIŽ significantly extended OS for patients compared to standard therapies.1
In patients randomized to the CARVYKTIŽ arm, CARVYKTIŽ reduced the risk of death by 45 percent compared to standard therapies demonstrating clinically meaningful responses for patients as early as after first relapse.1 Median progression-free survival (PFS) was NR in patients treated with CARVYKTIŽ (95 percent CI, 34.50 months NE) and 11.79 months (95 percent CI, 9.66-14.00) in patients treated with standard therapies demonstrating sustained deep and durable responses.1 Patients treated with CARVYKTIŽ had a 77 percent complete response or better, and 85 percent overall response rate. Patients treated with CARVYKTIŽ demonstrated a 62 percent minimal residual disease (MRD) negativity (10^-5) and 57 percent MRD-negativity (10^-6) compared to patients treated with standard therapies (18.5 percent, 9 percent), respectively.1 Median duration of response was NR (95 percent CI, NE-NE) in patients treated with CARVYKTIŽ and 18.7 months (95 percent CI, 12.9-23.7) for patients treated with standard therapies.1 Median time to symptom worsening based on the Multiple Myeloma Symptom and Impact Questionnaire (MySlm-Q) was NR (95 percent CI, NE-NE) with CARVYKTIŽ and 34.33 months (95 percent CI, 32,20-NE) with patients treated with standard therapies (HR, 0.38; 95 percent CI, 0.24-0.61; P<0.0001).1
The safety profile of cilta-cel versus standard therapies was consistent with previous analysis. In the safety analysis [cilta-cel, n=208, standard therapies, n=208], 97 percent of patients in both arms experienced grade 3/4 treatment-emergent adverse events (TEAEs) with cytopenia being the most common.1 Treatment-emergent infections occurred in 64 percent of patients in the CARVYKTIŽ arm and 76 percent of patients who received standard therapies with 28 percent and 30 percent being classified as grade 3/4, respectively.1 In the CARVYKTIŽ arm, there were seven patients with hematologic second primary malignancies, 50 patients died and of those patients, 21 died due to progressive disease.1 One patient treated with standard therapies experienced a hematologic second primary malignancy, 82 patients died and of those patients, 51 died due to progressive disease.1
"CARVYKTI is the first and only cell therapy approved for the treatment of patients with myeloma as early as second line, and now also the first and only cell therapy to improve overall survival and demonstrate improved patient quality-of-life outcomes versus standard therapies for patients with lenalidomide-refractory multiple myeloma," said Jordan Schecter, M.D., Vice President, Disease Area Leader, Multiple Myeloma, Innovative Medicine, Johnson & Johnson. "At Johnson & Johnson, we remain committed to addressing unmet need through the development of innovative treatments for patients and healthcare providers, and we look forward to submitting these results to local health authorities worldwide."
The U.S. FDA and European Commission approved CARVYKTIŽ for the treatment of adult patients with relapsed or refractory multiple myeloma who have received a least one prior line of therapy including a PI, IMiD, and are refractory to lenalidomide earlier this year. Globally, we have now launched CARVYKTIŽ in 5 countries and treated more than 3,500 patients.
About CARTITUDE-4
CARTITUDE-4 (NCT04181827) is the first randomized Phase 3 study evaluating the efficacy and safety of CARVYKTIŽ. The study compares CARVYKTIŽ with standard of care treatments PVd or DPd in adult patients with relapsed and lenalidomide-refractory multiple myeloma who received one to three prior lines of therapy. The primary endpoint of the study is progression-free survival (PFS); safety, OS, minimal residual disease negative rate and overall response rate are secondary endpoints.
About CARVYKTIŽ (ciltacabtagene autoleucel; cilta-cel)
CARVYKTIŽ (cilta-cel) received U.S. Food and Drug Administration approval in February 2022 for the treatment of adults with relapsed or refractory multiple myeloma after four or more prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. In April 2024, CARVYKTIŽ was approved in the U.S. for treatment of adult patients with relapsed or refractory multiple myeloma who have received at least one prior line of therapy including a proteasome inhibitor, an immunomodulatory agent, and who are refractory to lenalidomide, following a unanimous (11 to 0) FDA Oncologic Drugs Advisory Committee (ODAC) recommendation in support of this new indication. In April 2024, the European Medicines Agency (EMA) approved a Type II variation for CARVYKTIŽ for the treatment of adults with relapsed and refractory multiple myeloma who have received at least one prior therapy, including an immunomodulatory agent and a proteasome inhibitor, have demonstrated disease progression on the last therapy, and are refractory to lenalidomide. In September 2022, Japan's Ministry of Health, Labour and Welfare (MHLW) approved CARVYKTIŽ for the treatment of adults with relapsed or refractory multiple myeloma in patients that have no history of CAR-positive T cell infusion therapy targeting BCMA and who have received three or more lines of therapies, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 monoclonal antibody, and in whom multiple myeloma has not responded to or has relapsed following the most recent therapy.
CARVYKTIŽ is a BCMA-directed, genetically modified autologous T-cell immunotherapy, which involves reprogramming a patient's own T-cells with a transgene encoding chimeric antigen receptor (CAR) that directs the CAR-positive T cells to eliminate cells that express BCMA. BCMA is primarily expressed on the surface of malignant multiple myeloma B-lineage cells, as well as late-stage B cells and plasma cells. The CARVYKTIŽ CAR protein features two BCMA-targeting single domains designed to confer high avidity against human BCMA. Upon binding to BCMA-expressing cells, the CAR promotes T-cell activation, expansion, and elimination of target cells.
In December 2017, Janssen Biotech, Inc., a Johnson & Johnson company, entered into an exclusive worldwide license and collaboration agreement with Legend Biotech USA, Inc. to develop and commercialize CARVYKTIŽ.

About Multiple Myeloma
Multiple myeloma is an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.2 In multiple myeloma, these plasma cells proliferate and spread rapidly and replace normal cells in the bone marrow with tumors.3 Multiple myeloma is the third most common blood cancer worldwide and remains an incurable disease.4 In 2024, it was estimated that more than 35,000 people will be diagnosed with multiple myeloma in the U.S. and more than 12,000 people would die from the disease.5 People living with multiple myeloma have a 5-year survival rate of 59.8 percent.6 While some people diagnosed with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels and kidney problems or infections.7,8

WARNINGS AND PRECAUTIONS
Increased early mortality - In CARTITUDE-4, a (1:1) randomized controlled trial, there was a numerically higher percentage of early deaths in patients randomized to the CARVYKTIŽ treatment arm compared to the control arm. Among patients with deaths occurring within the first 10 months from randomization, a greater proportion (29/208; 14%) occurred in the CARVYKTIŽ arm compared to (25/211; 12%) in the control arm. Of the 29 deaths that occurred in the CARVYKTIŽ arm within the first 10 months of randomization, 10 deaths occurred prior to CARVYKTIŽ infusion, and 19 deaths occurred after CARVYKTIŽ infusion. Of the 10 deaths that occurred prior to CARVYKTIŽ infusion, all occurred due to disease progression, and none occurred due to adverse events. Of the 19 deaths that occurred after CARVYKTIŽ infusion, 3 occurred due to disease progression, and 16 occurred due to adverse events. The most common adverse events were due to infection (n=12).
Cytokine release syndrome (CRS), including fatal or life-threatening reactions, occurred following treatment with CARVYKTIŽ. Among patients receiving CARVYKTIŽ for RRMM in the CARTITUDE-1 & 4 studies (N=285), CRS occurred in 84% (238/285), including =Grade 3 CRS (ASCT 2019) in 4% (11/285) of patients. Median time to onset of CRS, any grade, was 7 days (range: 1 to 23 days). CRS resolved in 82% with a median duration of 4 days (range: 1 to 97 days). The most common manifestations of CRS in all patients combined (=10%) included fever (84%), hypotension (29%) and aspartate aminotransferase increased (11%). Serious events that may be associated with CRS include pyrexia, hemophagocytic lymphohistiocytosis, respiratory failure, disseminated intravascular coagulation, capillary leak syndrome, and supraventricular and ventricular tachycardia. CRS occurred in 78% of patients in CARTITUDE-4 (3% Grade 3 to 4) and in 95% of patients in CARTITUDE-1 (4% Grade 3 to 4).
Identify CRS based on clinical presentation. Evaluate for and treat other causes of fever, hypoxia, and hypotension. CRS has been reported to be associated with findings of HLH/MAS, and the physiology of the syndromes may overlap. HLH/MAS is a potentially life-threatening condition. In patients with progressive symptoms of CRS or refractory CRS despite treatment, evaluate for evidence of HLH/MAS.
Ensure that a minimum of two doses of tocilizumab are available prior to infusion of CARVYKTIŽ.
Of the 285 patients who received CARVYKTIŽ in clinical trials, 53% (150/285) patients received tocilizumab; 35% (100/285) received a single dose, while 18% (50/285) received more than 1 dose of tocilizumab. Overall, 14% (39/285) of patients received at least one dose of corticosteroids for treatment of CRS.
Monitor patients at least daily for 10 days following CARVYKTIŽ infusion at a REMS-certified healthcare facility for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for at least 4 weeks after infusion. At the first sign of CRS, immediately institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids.
Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time.
Neurologic toxicities, which may be severe, life-threatening, or fatal, occurred following treatment with CARVYKTIŽ. Neurologic toxicities included ICANS, neurologic toxicity with signs and symptoms of parkinsonism, GBS, immune mediated myelitis, peripheral neuropathies, and cranial nerve palsies. Counsel patients on the signs and symptoms of these neurologic toxicities, and on the delayed nature of onset of some of these toxicities. Instruct patients to seek immediate medical attention for further assessment and management if signs or symptoms of any of these neurologic toxicities occur at any time.
Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies for RRMM, one or more neurologic toxicities occurred in 24% (69/285), including =Grade 3 cases in 7% (19/285) of patients. Median time to onset was 10 days (range: 1 to 101) with 63/69 (91%) of cases developing by 30 days. Neurologic toxicities resolved in 72% (50/69) of patients with a median duration to resolution of 23 days (range: 1 to 544). Of patients developing neurotoxicity, 96% (66/69) also developed CRS. Subtypes of neurologic toxicities included ICANS in 13%, peripheral neuropathy in 7%, cranial nerve palsy in 7%, parkinsonism in 3%, and immune mediated myelitis in 0.4% of the patients.
Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS): Patients receiving CARVYKTIŽ may experience fatal or life-threatening ICANS following treatment with CARVYKTIŽ, including before CRS onset, concurrently with CRS, after CRS resolution, or in the absence of CRS.
Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, ICANS occurred in 13% (36/285), including Grade =3 in 2% (6/285) of the patients. Median time to onset of ICANS was 8 days (range: 1 to 28 days). ICANS resolved in 30 of 36 (83%) of patients with a median time to resolution of 3 days (range: 1 to 143 days). Median duration of ICANS was 6 days (range: 1 to 1229 days) in all patients including those with ongoing neurologic events at the time of death or data cut off. Of patients with ICANS 97% (35/36) had CRS. The onset of ICANS occurred during CRS in 69% of patients, before and after the onset of CRS in 14% of patients respectively.
Immune Effector Cell-associated Neurotoxicity Syndrome occurred in 7% of patients in CARTITUDE-4 (0.5% Grade 3) and in 23% of patients in CARTITUDE-1 (3% Grade 3). The most frequent =2% manifestations of ICANS included encephalopathy (12%), aphasia (4%), headache (3%), motor dysfunction (3%), ataxia (2%) and sleep disorder (2%).
Monitor patients at least daily for 10 days following CARVYKTIŽ infusion at the REMS-certified healthcare facility for signs and symptoms of ICANS. Rule out other causes of ICANS symptoms. Monitor patients for signs or symptoms of ICANS for at least 4 weeks after infusion and treat promptly. Neurologic toxicity should be managed with supportive care and/or corticosteroids as needed.
Parkinsonism: Neurologic toxicity with parkinsonism has been reported in clinical trials of CARVYKTIŽ. Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, parkinsonism occurred in 3% (8/285), including Grade = 3 in 2% (5/285) of the patients. Median time to onset of parkinsonism was 56 days (range: 14 to 914 days). Parkinsonism resolved in 1 of 8 (13%) of patients with a median time to resolution of 523 days. Median duration of parkinsonism was 243.5 days (range: 62 to 720 days) in all patients including those with ongoing neurologic events at the time of death or data cut off. The onset of parkinsonism occurred after CRS for all patients and after ICANS for 6 patients.
Parkinsonism occurred in 1% of patients in CARTITUDE-4 (no Grade 3 to 4) and in 6% of patients in CARTITUDE-1 (4% Grade 3 to 4).
Manifestations of parkinsonism included movement disorders, cognitive impairment, and personality changes. Monitor patients for signs and symptoms of parkinsonism that may be delayed in onset and managed with supportive care measures. There is limited efficacy information with medications used for the treatment of Parkinson's disease for the improvement or resolution of parkinsonism symptoms following CARVYKTIŽ treatment.
Guillain-Barré syndrome: A fatal outcome following GBS occurred following treatment with CARVYKTIŽ despite treatment with intravenous immunoglobulins. Symptoms reported include those consistent with Miller-Fisher variant of GBS, encephalopathy, motor weakness, speech disturbances, and polyradiculoneuritis.
Monitor for GBS. Evaluate patients presenting with peripheral neuropathy for GBS. Consider treatment of GBS with supportive care measures and in conjunction with immunoglobulins and plasma exchange, depending on severity of GBS.
Immune mediated myelitis: Grade 3 myelitis occurred 25 days following treatment with CARVYKTIŽ in CARTITUDE-4 in a patient who received CARVYKTIŽ as subsequent therapy. Symptoms reported included hypoesthesia of the lower extremities and the lower abdomen with impaired sphincter control. Symptoms improved with the use of corticosteroids and intravenous immune globulin. Myelitis was ongoing at the time of death from other cause.
Peripheral neuropathy occurred following treatment with CARVYKTIŽ. Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, peripheral neuropathy occurred in 7% (21/285), including Grade =3 in 1% (3/285) of the patients. Median time to onset of peripheral neuropathy was 57 days (range: 1 to 914 days). Peripheral neuropathy resolved in 11 of 21 (52%) of patients with a median time to resolution of 58 days (range: 1 to 215 days). Median duration of peripheral neuropathy was 149.5 days (range: 1 to 692 days) in all patients including those with ongoing neurologic events at the time of death or data cut off.
Peripheral neuropathies occurred in 7% of patients in CARTITUDE-4 (0.5% Grade 3 to 4) and in 7% of patients in CARTITUDE-1 (2% Grade 3 to 4). Monitor patients for signs and symptoms of peripheral neuropathies. Patients who experience peripheral neuropathy may also experience cranial nerve palsies or GBS.
Cranial nerve palsies occurred following treatment with CARVYKTIŽ. Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, cranial nerve palsies occurred in 7% (19/285), including Grade =3 in 1% (1/285) of the patients. Median time to onset of cranial nerve palsies was 21 days (range: 17 to 101 days). Cranial nerve palsies resolved in 17 of 19 (89%) of patients with a median time to resolution of 66 days (range: 1 to 209 days). Median duration of cranial nerve palsies was 70 days (range: 1 to 262 days) in all patients including those with ongoing neurologic events at the time of death or data cut off. Cranial nerve palsies occurred in 9% of patients in CARTITUDE-4 (1% Grade 3 to 4) and in 3% of patients in CARTITUDE-1 (1% Grade 3 to 4).
The most frequent cranial nerve affected was the 7th cranial nerve. Additionally, cranial nerves III, V, and VI have been reported to be affected.
Monitor patients for signs and symptoms of cranial nerve palsies. Consider management with systemic corticosteroids, depending on the severity and progression of signs and symptoms.
Hemophagocytic Lymphohistiocytosis (HLH)/Macrophage Activation Syndrome (MAS): Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, HLH/MAS occurred in 1% (3/285) of patients. All events of HLH/MAS had onset within 99 days of receiving CARVYKTIŽ, with a median onset of 10 days (range: 8 to 99 days) and all occurred in the setting of ongoing or worsening CRS. The manifestations of HLH/MAS included hyperferritinemia, hypotension, hypoxia with diffuse alveolar damage, coagulopathy and hemorrhage, cytopenia and multi-organ dysfunction, including renal dysfunction and respiratory failure.
Patients who develop HLH/MAS have an increased risk of severe bleeding. Monitor hematologic parameters in patients with HLH/MAS and transfuse per institutional guidelines. Fatal cases of HLH/MAS occurred following treatment with CARVYKTIŽ.
HLH is a life-threatening condition with a high mortality rate if not recognized and treated early. Treatment of HLH/MAS should be administered per institutional standards.
CARVYKTIŽ REMS: Because of the risk of CRS and neurologic toxicities, CARVYKTIŽ is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the CARVYKTIŽ REMS.
Further information is available at https://www.carvyktirems.com/ or 1-844-672-0067.
Prolonged and Recurrent Cytopenias: Patients may exhibit prolonged and recurrent cytopenias following lymphodepleting chemotherapy and CARVYKTIŽ infusion.
Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, Grade 3 or higher cytopenias not resolved by day 30 following CARVYKTIŽ infusion occurred in 62% (176/285) of the patients and included thrombocytopenia 33% (94/285), neutropenia 27% (76/285), lymphopenia 24% (67/285) and anemia 2% (6/285). After Day 60 following CARVYKTIŽ infusion 22%, 20%, 5%, and 6% of patients had a recurrence of Grade 3 or 4 lymphopenia, neutropenia, thrombocytopenia, and anemia respectively, after initial recovery of their Grade 3 or 4 cytopenia. Seventy-seven percent (219/285) of patients had one, two or three or more recurrences of Grade 3 or 4 cytopenias after initial recovery of Grade 3 or 4 cytopenia. Sixteen and 25 patients had Grade 3 or 4 neutropenia and thrombocytopenia, respectively, at the time of death.
Monitor blood counts prior to and after CARVYKTIŽ infusion. Manage cytopenias with growth factors and blood product transfusion support according to local institutional guidelines.
Infections: CARVYKTIŽ should not be administered to patients with active infection or inflammatory disorders. Severe, life-threatening, or fatal infections, occurred in patients after CARVYKTIŽ infusion.
Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, infections occurred in 57% (163/285), including =Grade 3 in 24% (69/285) of patients. Grade 3 or 4 infections with an unspecified pathogen occurred in 12%, viral infections in 6%, bacterial infections in 5%, and fungal infections in 1% of patients. Overall, 5% (13/285) of patients had Grade 5 infections, 2.5% of which were due to COVID-19. Patients treated with CARVYKTIŽ had an increased rate of fatal COVID-19 infections compared to the standard therapy arm.
Monitor patients for signs and symptoms of infection before and after CARVYKTIŽ infusion and treat patients appropriately. Administer prophylactic, pre-emptive and/or therapeutic antimicrobials according to the standard institutional guidelines. Febrile neutropenia was observed in 5% of patients after CARVYKTIŽ infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids and other supportive care, as medically indicated. Counsel patients on the importance of prevention measures. Follow institutional guidelines for the vaccination and management of immunocompromised patients with COVID-19.
Viral Reactivation: Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure and death, can occur in patients with hypogammaglobulinemia. Perform screening for Cytomegalovirus (CMV), HBV, hepatitis C virus (HCV), and human immunodeficiency virus (HIV) or any other infectious agents if clinically indicated in accordance with clinical guidelines before collection of cells for manufacturing. Consider antiviral therapy to prevent viral reactivation per local institutional guidelines/clinical practice.
Hypogammaglobulinemia: can occur in patients receiving treatment with CARVYKTIŽ. Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, hypogammaglobulinemia adverse event was reported in 36% (102/285) of patients; laboratory IgG levels fell below 500mg/dl after infusion in 93% (265/285) of patients. Hypogammaglobulinemia either as an adverse reaction or laboratory IgG level below 500mg/dl, after infusion occurred in 94% (267/285) of patients treated. Fifty six percent (161/285) of patients received intravenous immunoglobulin (IVIG) post CARVYKTIŽ for either an adverse reaction or prophylaxis.
Monitor immunoglobulin levels after treatment with CARVYKTIŽ and administer IVIG for IgG <400 mg/dL. Manage per local institutional guidelines, including infection precautions and antibiotic or antiviral prophylaxis.
Use of Live Vaccines: The safety of immunization with live viral vaccines during or following CARVYKTIŽ treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during CARVYKTIŽ treatment, and until immune recovery following treatment with CARVYKTIŽ.
Hypersensitivity Reactions occurred following treatment with CARVYKTIŽ. Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, hypersensitivity reactions occurred in 5% (13/285), all of which were =Grade 2. Manifestations of hypersensitivity reactions included flushing, chest discomfort, tachycardia, wheezing, tremor, burning sensation, non-cardiac chest pain, and pyrexia.
Serious hypersensitivity reactions, including anaphylaxis, may be due to the dimethyl sulfoxide (DMSO) in CARVYKTIŽ. Patients should be carefully monitored for 2 hours after infusion for signs and symptoms of severe reaction. Treat promptly and manage patients appropriately according to the severity of the hypersensitivity reaction.
Secondary Malignancies: Patients treated with CARVYKTIŽ may develop secondary malignancies. Among patients receiving CARVYKTIŽ in the CARTITUDE-1 & 4 studies, myeloid neoplasms occurred in 5% (13/285) of patients (9 cases of myelodysplastic syndrome, 3 cases of acute myeloid leukemia, and 1 case of myelodysplastic syndrome followed by acute myeloid leukemia). The median time to onset of myeloid neoplasms was 447 days (range: 56 to 870 days) after treatment with CARVYKTIŽ. Ten of these 13 patients died following the development of myeloid neoplasms; 2 of the 13 cases of myeloid neoplasm occurred after initiation of subsequent antimyeloma therapy. Cases of myelodysplastic syndrome and acute myeloid leukemia have also been reported in the post marketing setting. T-cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T-cell immunotherapies, including CARVYKTIŽ. Mature T-cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusions, and may include fatal outcomes.
Monitor life-long for secondary malignancies. In the event that a secondary malignancy occurs, contact Janssen Biotech, Inc. at 1-800-526-7736 for reporting and to obtain instructions on collection of patient samples.
Effects on Ability to Drive and Use Machines: Due to the potential for neurologic events, including altered mental status, seizures, neurocognitive decline or neuropathy, patients receiving CARVYKTIŽ are at risk for altered or decreased consciousness or coordination in the 8 weeks following CARVYKTIŽ infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery during this initial period, and in the event of new onset of any neurologic toxicities.
