SUMMARY

• Johnson & Johnson does not recommend the use of CARVYKTI in a manner that is inconsistent with the approved labeling.
• Outpatient administration of CARVYKTI is being explored in the CARTITUDE-2 and CARTITUDE-5 studies.^1,2 
• CARTITUDE-2 is a phase 2, open-label, multicohort, single-arm, multicenter study evaluating CARVYKTI in patients with multiple myeloma (MM) in various clinical settings.^3-6
  • Patients are assessed for suitability for outpatient administration at the time of apheresis, prior to lymphodepletion, and again prior to CARVYKTI infusion based on investigator’s discretion, patient’s willingness, institutional guidance, and sponsor’s approval.¹
  • Cohort A evaluates patients with relapsed/refractory multiple myeloma (RRMM) who received 1-3 prior lines of therapy (LOTs) and are refractory to lenalidomide.⁴
    • One patient was treated in an outpatient setting in Cohort A.⁴
      • Grade 2 cytokine release syndrome (CRS) occurred 9 days after CARVYKTI infusion, with a duration of 2 days; grade 2 isolated facial paralysis occurred 29 days after CARVYKTI infusion and resolved completely within 51 days of onset after treatment with dexamethasone.⁴
  • Cohort B evaluates patients with early relapse (≤12 months after frontline therapy or ≤12 months after autologous stem cell transplant [ASCT]).⁵
    • One patient was treated in an outpatient setting in Cohort B.⁵

CLINICAL DATA - REAL-WORLD STUDIES

Outpatient vs Inpatient CARVYKTI Administration in Patients With RRMM: Real‑World Claims Analysis

Janakiram et al (2025)⁷ conducted a retrospective, real‑world claims analysis evaluating the feasibility and HCRU associated with outpatient versus inpatient administration of CARVYKTI in patients with RRMM treated after ≥4 prior LOTs.

Study Design/Methods

• Open claims from the Komodo Research Database (January 1, 2016, to June 30, 2024) were used in a retrospective longitudinal cohort design.⁷
• The index date was defined as the date of CARVYKTI infusion on or after February 28, 2022. The baseline period comprised the 12 months prior to the index date; follow‑up period was defined as the period from the index date to the earliest of 30 days after CARVYKTI infusion, end of clinical activity, death, or end of data availability.⁷
• Patients were assigned to mutually exclusive inpatient or outpatient cohorts based on the CARVYKTI administration setting; outpatient administration was defined as infusion occurring in an outpatient setting.⁷
• Inclusion criteria (N=517):
  • Patients aged ≥18 years at the index date who received CARVYKTI after ≥4 prior LOTs on or after index date and had ≥12 months of clinical activity prior to the index date.⁷
  • ≥1 diagnosis of MM (International Classification of Diseases, 10th Revision [ICD-10-CM]: C90) on or prior to the index date.⁷
• Exclusion criteria (N=275)⁷:

  • Clinical trial participation on or prior to the index date (ICD-10-CM: Z00.6; Healthcare Common Procedure Coding System: S9988, S9990, S9991, S9992, S9994, S9996)
  • No claims for lymphodepleting therapy agents (ie, cyclophosphamide, fludarabine, or bendamustine) within 14 days before or 30 days after the index date
• Patients were monitored for adverse events (ie, CRS, fever, ICANS, pancytopenia) and related management strategies (ie, tocilizumab, dexamethasone), 30-day mortality rate and HCRU, including post-infusion hospitalization days.⁷

Results

• A total of 242 eligible patients were identified; 148 patients received CARVYKTI in the inpatient setting and 94 patients received CARVYKTI in the outpatient setting.⁷
• Baseline patient characteristics were similar between inpatients vs outpatients (median age, 64 years vs 64 years; female sex proportion, 47.3% vs 42.6%; median Quan-Charlson Comorbidity Index, 5 vs 5; median LOT of CARVYKTI, 6 vs 5).⁷

Safety

• Adverse events from the inpatient and outpatient cohorts are summarized in Table: Adverse Events and Management Strategies Post Infusion.

Healthcare Resource Utilization

• Among 148 patients in the inpatient cohort, the median length of the index admission was 15 days (mean, 15; standard deviation, 5.8), and 17 patients (11.5%) were re‑admitted within the first 30 days following discharge from the initial hospitalization.⁷
• HCRU among 94 patients in the outpatient cohort is summarized in Table: HCRU During the First 30 Days Post Infusion.
• Among patients with ≥1 inpatient day during the first 30 days post‑infusion, hospitalization days remained consistently higher in the inpatient cohort compared with the outpatient cohort across all evaluated timepoints, as summarized in Table: Number of IP Days Post Infusion Among Patients With ≥1 IP Day.
• In the outpatient cohort, 31.9% of patients (n=30) did not require hospitalization during the first 30 days post infusion.⁷

Outpatient CARVYKTI Administration in Patients With RRMM: Real‑World Analysis

Waqar et al (2024)⁸ conducted a single-center, retrospective study evaluating the outpatient administration of CARVYKTI in patients with RRMM through an established dedicated outpatient cellular therapy service, Immune Cell Therapy (ICE T), at the Moffitt Cancer Center (MCC).

Study Design/Methods

• The study was conducted at MCC between May 2022 and May 2023, with a focus on the first 30 days after CARVYKTI infusion in patients with RRMM.⁸
• Initially, patients received lymphodepleting chemotherapy as outpatient; then received CAR-T infusion and underwent monitoring as inpatient and were later discharged to the outpatient ICE T service.⁸
• Thereafter, the practice was modified to provide lymphodepleting chemotherapy, CARVYKTI infusion, and monitoring in the outpatient setting. Patients were admitted as inpatient as per clinical needs.⁸
• Patients were monitored and assessed for CRS and ICANS through day +30 post infusion.⁸

Results

• A total of 43 patients with RRMM were included in this analysis. The inpatient group included 6 patients (14%), the scheduled outpatient to inpatient group included 10 patients (23.3%) and the outpatient group included 27 patients (62.8%).⁸
• Baseline characteristics across inpatient (n=6), outpatient (n=27), and scheduled outpatienttoinpatient (n=10) groups included median age (62 years, 61 years, and 58.5 years), male sex proportion (83.3%, 44.4%, and 40% of patients), prior autologous hematopoietic cell transplantation (33.3%, 88.9%, and 90% of patients), and median number of prior LOTs of (5, 5, and 6), respectively.⁸

Efficacy

• OS and PFS rates were similar across the administration types. At a median follow-up of 7.7 months (range, 2.9-14.4), the 1-year OS was 96.3% (95% confidence interval [CI], 76.5-99.5; P=0.068) and the 1-year PFS was 85.8% (95% CI, 60.6-95.5; P=0.10) for the surviving patients from the outpatient group.⁸

Safety

• The median hospitalization duration for the inpatient group was 19 days (range, 9-36).⁸
  • Patients from the inpatient group were hospitalized for MM-related conditions (n=4), chemotherapy-related gastrointestinal toxicity (n=1), and patient preference (n=1).
• A total of 25 patients (92.6%) from the outpatient group were admitted after CARVYKTI infusion. The median hospitalization duration was 4 days (range, 1-33).⁸
  • Of these, 22 patients (81.5%) were primarily hospitalized for CRS and 5 patients were hospitalized for clinical indications (arrhythmia, infection, and social reasons).
  • Three patients (11.1%) who underwent outpatient ICE T, required a second hospital admission within 30 days of CARVYKTI infusion (2 for ICANS and 1 for infection).
• All patients from the scheduled outpatient to inpatient group were admitted on day -1 as planned with a median hospitalization duration of 11 days.⁸

Outpatient CARVYKTI Administration: Safety and Feasibility

Ly et al (2024)⁹ conducted a retrospective study on the safety and feasibility of CARVYKTI administration in an outpatient setting.

Study Design/Methods

• The study included patients who received CARVYKTI in an outpatient setting, with a data cutoff date of October 1, 2023.⁹
• CRS, ICANS, and IEC-HS were graded as per American Society for Transplantation and Cellular Therapy (ASTCT) 2019 and 2023 criteria, and responses were graded using standard criteria.⁹
• Patients received outpatient lymphodepletion chemotherapy and outpatient CARVYKTI infusion; daily monitoring was conducted for 14 days in the extended hour outpatient unit.⁹
• The first patient was preemptively admitted after CARVYKTI infusion to monitor CARVYKTI safety before instituting the full outpatient paradigm.⁹

Results

• A total of 14 patients received CARVYKTI in an outpatient setting, of which 1 patient had nervous system involvement.⁹
• Baseline characteristics of patients treated with outpatient CARVYKTI (N=14) included a median age (58.5 years), female sex proportion (36% of patients), Revised International Staging System stage I, II, and III disease (36%, 36%, and 21% of patients, respectively), a median of 9 prior LOTs, prior autologous/allogeneic transplantation in 64% of patients, and bridging therapy prior to chimeric antigen receptor T-cell therapy infusion in 72% of patients.⁹
• The median follow-up was 99.5 days (range, 13-282).⁹

Efficacy

Response

• Eleven patients were evaluable for ≥1 response assessment; of these, 5 patients (45%) showed ≥CR.⁹ The response rates in patients who received CARVYKTI is presented in Table: Response Rates in Evaluable CARVYKTI-Treated Patients.

Safety

• A summary of safety outcomes are presented in Table: Summary of Safety Outcomes.
