- Johnson & Johnson's Phase 2 RedirecTT-1 study shows a 78.9% overall response rate for new multiple myeloma therapies.
- TALVEY® and TECVAYLI® represent significant advancements in treating triple-class exposed relapsed/refractory multiple myeloma with extramedullary disease.
- The company's commitment to innovative cancer therapies aims to improve patient care and survivorship in complex malignancies.
Johnson & Johnson's Breakthrough in Multiple Myeloma Treatment
Johnson & Johnson announces groundbreaking results from the Phase 2 RedirecTT-1 study, which evaluates the investigational combination therapy of TALVEY® (talquetamab-tgvs) and TECVAYLI® (teclistamab-cqyv) for treating patients with triple-class exposed relapsed/refractory multiple myeloma (RRMM) that also presents with extramedullary disease (EMD). The findings reveal an impressive overall response rate (ORR) of 78.9%, significantly surpassing the less than 40% ORR associated with current standard therapies for patients with EMD. This study represents a major advancement in addressing the treatment challenges posed by EMD, characterized by the presence of plasmacytomas in soft tissues and organs, which complicates therapeutic options and generally leads to poorer patient outcomes.
Conducted with a cohort of 90 participants, the RedirecTT-1 trial is the largest of its kind focusing on EMD in patients with multiple myeloma. Notably, 84.4% of the enrolled patients are triple-class refractory, and 35.6% are penta-drug refractory, indicating a population that has exhausted most available treatment options. Furthermore, 20% of patients included in the study have previously undergone BCMA CAR-T therapy, showcasing the severe treatment landscape these individuals navigate. The results suggest that dual targeting of GPRC5D and BCMA—two critical antigens involved in multiple myeloma—could enhance treatment efficacy by mitigating target antigen-related escape mechanisms, ultimately leading to improved response rates and deeper treatment responses.
Dr. Yael Cohen, Head of the Myeloma Unit at Tel-Aviv Sourasky Medical Center, highlights the potential of this combination therapy to offer durable responses in a patient population where existing therapies frequently fall short. The RedirecTT-1 study underscores the necessity for innovative treatment strategies in managing aggressive forms of multiple myeloma, marking TALVEY and TECVAYLI as significant advancements in the therapeutic landscape for EMD patients. As these findings are presented at the 2025 European Hematology Association Congress, they pave the way for future research and development aimed at improving treatment outcomes for those battling this challenging disease.
In addition to these promising results, Johnson & Johnson's commitment to advancing cancer therapies aligns with its broader strategic focus on innovative healthcare solutions. By leveraging the potential of new combination therapies, the company aims to enhance patient care and improve survivorship rates in complex malignancies. As the landscape of multiple myeloma treatment evolves, Johnson & Johnson's contributions could play a pivotal role in transforming the prognosis for patients facing relapsed and refractory forms of this disease.
