32 patients with autoimmune disease treated with AlloNK plus anti-CD20 monoclonal antibody (mAb) as of October 1, 2025, data cutoff All patients received AlloNK as outpatients, and the majority were treated in community rheumatology trial sites with no specialized oncology oversight, demonstrating the feasibility of administering this regimen outside the hospital setting No cytokine release syndrome (CRS), or immune effector cell-associated neurotoxicity syndrome (ICANS) Consistent and complete B-cell deple ...

Core Viewpoint - Sanofi has completed the acquisition of DR-0201, now named SAR448501, to enhance its immunology pipeline and position itself as a leading immunology company [1][2]. Group 1: Acquisition Details - The acquisition involved an upfront payment of $600 million, with potential future payments totaling $1.3 billion based on development and launch milestones [4]. - Dren Bio will continue to operate independently to advance its pipeline of antibody therapeutics [4]. Group 2: Product Information - SAR448501 is a targeted bispecific myeloid cell engager that has demonstrated robust B-cell depletion in pre-clinical and early clinical studies [2]. - The product targets specific tissue-resident and trafficking myeloid cells to induce deep B-cell depletion through targeted phagocytosis [2]. Group 3: Clinical Implications - Recent studies suggest that deep B-cell depletion may reset the adaptive immune system, potentially leading to sustained treatment-free remission in patients with refractory B-cell mediated autoimmune diseases, such as lupus [3]. - There remains a significant unmet medical need in treating these autoimmune diseases [3].
