  • 89 percent of evaluable patients achieved minimal residual disease (MRD) negativity with CARVYKTI® after three-year follow-up in CARTITUDE-4 study; the majority in less than 2 months

  • Results add to the overall survival (OS) benefit recently reported making CARVYKTI® the first and only cell therapy to significantly extend OS versus standard therapies in multiple myeloma

  • Landmark Phase 3 CARTITUDE-4 study data featured as an oral presentation at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition

SOMERSET, N.J., Dec. 09, 2024 (GLOBE NEWSWIRE) -- Legend Biotech Corporation (NASDAQ: LEGN) (Legend Biotech), a global leader in cell therapy, announced today new results from the Phase 3 CARTITUDE-4 study that show a single infusion of CARVYKTI® (ciltacabtagene autoleucel; cilta-cel) provided significantly higher rates of minimal residual disease (MRD)-negativity in patients with relapsed or lenalidomide-refractory multiple myeloma who have received at least one prior line of therapy, including a proteasome inhibitor (PI) and an immunomodulatory agent (IMiD, compared to standard therapies of pomalidomide, bortezomib, and dexamethasone (PVd) or daratumumab, pomalidomide, and dexamethasone (DPd).1 MRD negativity is a prognostic marker of prolonged survival outcomes for patients with multiple myeloma.1 These results reinforce the clinical value of CARVYKTI® as early as second line and support the recent achievement of overall survival (OS) benefit versus standard therapies1. The MRD negativity findings were featured as an oral presentation at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition (Abstract #1032) in San Diego, California.1

“The MRD data further underscores the benefits of treatment with CARVYKTI,” said Yi Lin, M.D., Ph.D., hematologist and oncologist at Mayo Clinic, Rochester, MN. “These new findings support CARVYKTI as a transformative therapeutic option, leading to improved progression-free survival, overall survival, and now minimal residual disease negativity.”

The Phase 3 CARTITUDE-4 study evaluated CARVYKTI® in comparison to standard therapies of PVd or DPd for the treatment of adults with relapsed or refractory multiple myeloma who have received one to three prior lines of therapy, including a PI and IMiD, and who were lenalidomide-refractory. In the trial, 208 adults were randomized to receive CARVYKTI®, and 211 to receive standard therapies.

The study assessed patients for MRD negativity at the 10-5 threshold (cilta-cel, n=145, standard therapies, n=103). At a median follow-up of almost three years (34 months), evaluable patients treated with CARVYKTI® achieved an MRD-negativity rate of 89% versus 38% for those treated with standard therapies (P<0.0001). High rates of overall MRD-negativity were rapidly achieved with CARVYKTI® with 69% of MRD-evaluable patients by day 56. At data cutoff, sustained MRD-negative ≥CR of at least 12 months was achieved in 52% of MRD-evaluable patients in the CARVYKTI® arm vs. 10% in the standard of care arm (P<0.0001). A post-hoc comparison of the CARTITUDE-4 and CARTITUDE-1 studies (1-3 versus 3+ prior lines of therapy) showed higher rates of MRD negativity, PFS, and OS were achieved when CARVYKTI® was administered earlier in the treatment regimen.
