J&J(US:JNJ) 智通财经网·2025-12-11 08:31Core Insights - Morgan Stanley highlights Johnson & Johnson's (JNJ.US) recent clinical data presented at the American Society of Hematology (ASH) annual meeting, particularly the promising results of the Tecvayli and Darzalex combination therapy (Tec-Dara) for relapsed/refractory multiple myeloma (RRMM) in the phase III trial (MajesTEC-3) [1] Group 1: Clinical Trial Results - The MajesTEC-3 trial included 587 patients, showing that the Tec-Dara combination significantly outperformed the control group (DPd/DVd regimen) in key efficacy metrics [1] - The combination therapy also reduced the risk of patient mortality and extended treatment duration, benefiting even those previously treated with anti-CD38 therapy [1] Group 2: Safety Profile - The incidence of grade 3/4 treatment-related adverse events for the Tec-Dara combination was similar to the control group, with low treatment discontinuation rates [2] - Although the combination had a higher infection rate initially, the introduction of an immunoglobulin prophylaxis regimen in February 2023 led to a significant decrease in grade 3 and above infection rates after six months, with only one case of fatal infection reported [2] - The incidence of cytokine release syndrome was 60.1%, while immune effector cell-associated neurotoxicity syndrome occurred in only 1.0% of patients [2] Group 3: Market Potential - Morgan Stanley predicts that Tecvayli's global sales will grow from $1 billion in 2026 to $9.3 billion by 2033, with its efficacy being competitive against Legend Biotech's and Johnson & Johnson's BCMA CAR-T therapy, Carvykti [2] - Darzalex, expected to generate $14 billion in annual sales, has established a strong position in frontline treatment, with approximately 76% of U.S. patients remaining sensitive to it after their first relapse, laying a foundation for Tec-Dara's advancement in treatment lines [2] Group 4: New CAR-T Therapy - Morgan Stanley also mentioned Johnson & Johnson's collaboration with Kelonia on a new CAR-T therapy, KLN-1010, which uses a lentiviral vector for delivery without preconditioning, potentially reducing logistical burdens and production costs [3] - In a preliminary phase I trial involving four patients who had undergone at least three lines of treatment, all achieved minimal residual disease negativity, with one case of complete response and three cases of partial response, demonstrating good safety without neurotoxic side effects [3] - If subsequent trials are successful, KLN-1010 could become a new treatment option for multiple myeloma, further strengthening Johnson & Johnson's leadership in this field and posing long-term competitive pressure on existing BCMA CAR-T therapies [3]
