Summary

• CARTITUDE-1 is a phase 1b/2, open label, multicenter study of CARVYKTI in patients with relapsed or refractory multiple myeloma (RRMM) after ≥ 3 prior lines of therapy (LOT) including a proteasome inhibitor (PI), an immunomodulatory drug, and an anti-CD38 monoclonal antibody (mAb).^1-3
• CARTITUDE-4 is a phase 3, open-label, multicenter study evaluating CARVYKTI versus standard care regimens, DARZALEX FASPRO (daratumumab and hyaluronidase), pomalidomide, and dexamethasone (DPd) or pomalidomide, bortezomib, and dexamethasone (PVd), in patients with RRMM who received 1-3 prior LOT, including a proteasome inhibitor and an immunomodulatory drug, and are refractory to lenalidomide.⁴
• The washout periods for CARTITUDE-1 and CARTITUDE-4 are summarized below.

Clinical data - CARTITUDE-1 - PHASE 1B/2 STUDY

CARTITUDE-1 (NCT03548207) was a phase 1b/2, open-label study evaluating the efficacy and safety of CARVYKTI in patients with RRMM after ≥3 prior LOT including a PI, an immunomodulatory drug, and an anti-CD38 mAb.^1-3 

• In CARTITUDE-1, a washout period from bridging therapy was required prior to administration of the lymphodepleting chemotherapy regimen of cyclophosphamide and fludarabine.⁵
• Patients were excluded from participation in the study if they received prior antitumor therapy as follows, prior to apheresis/leukapheresis⁵:
  • Targeted therapy, epigenetic therapy, or treatment with an investigational drug or used an invasive investigational medical device within 14 days or at least 5 half-lives, whichever is less.
  • Monoclonal antibody treatment for multiple myeloma within 21 days.
  • Cytotoxic therapy within 14 days.
  • PI within 14 days.
  • Immunomodulatory agent within 7 days.
  • Radiotherapy within 14 days. However, patients were eligible irrespective of the end date of radiotherapy if the radiation portal covered ≤5% of the bone marrow reserve.
  • Received a cumulative dose of corticosteroids equivalent to ≥70 mg prednisone within the 7 days prior to apheresis or the first dose of lymphodepleting regimen.

Clinical data - CARTITUDE-4 - Phase 3 study

CARTITUDE-4 (NCT04181827) is a phase 3, randomized, open-label study evaluating the efficacy and safety of CARVYKTI versus standard care (physician's choice of DPd or PVd) in adult patients with lenalidomide-refractory MM after 1-3 prior LOT.⁴

• In CARTITUDE-4, patients in the CARVYKTI arm had to have received a washout period that occurred from the last dose of bridging therapy until prior to initiating the conditioning regimen (cyclophosphamide and fludarabine), the length of which depended on whether PVd or DPd was given as bridging therapy.⁶ 
  • Cycles beyond bridging cycle 1 may have been truncated to allow for adequate washout and minimize time off therapy.
• Patients were excluded from participation in the study if they received prior antitumor therapy as follows, prior to randomization⁶:
  • Targeted therapy, epigenetic therapy, or treatment with an investigational drug or used an invasive investigational medical device within 14 days or at least 5 half-lives, whichever is less.
  • Investigational vaccine within 4 weeks.
  • Monoclonal antibody treatment within 21 days.
  • Cytotoxic therapy within 14 days.
  • PI within 14 days.
  • Immunomodulatory agent therapy within 7 days.
  • Radiotherapy within 14 days. However, if the radiation is given for palliative purposes and the radiation portal covered ≤5% of the bone marrow reserve, the patient is eligible irrespective of the end date of radiotherapy. Radiotherapy within 14 days on measurable extramedullary plasmacytoma(s) is not permitted even in the setting of palliation for symptomatic management.
  • Received a cumulative dose of corticosteroids equivalent to ≥70 mg of prednisone within the 7 days prior to randomization or conditioning regimen.
