Haitong Securities International·2026-01-13 06:58Investment Rating - The report maintains a positive outlook on the development of dual and triple antibodies in multiple myeloma (MM) and recommends monitoring the progress of TCE monotherapy and combination therapies in MM, including the EMD population [1][15]. Core Insights - The 67th ASH Annual Meeting highlighted significant advancements in hematology, particularly in the treatment of multiple myeloma, diffuse large B-cell lymphoma (DLBCL), and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) [31]. - In multiple myeloma, the Tec-Dara combination therapy demonstrated a 36-month overall survival (OS) rate of 83.3%, significantly higher than the 65.0% in the control group, with a hazard ratio (HR) of 0.46 [32]. - The MSD ROR1 ADC showed promising first-line potential in DLBCL, with 24-month OS and progression-free survival (PFS) rates of 94% and 84%, respectively, outperforming existing treatments [33]. - Eli Lilly's Pirto showed improved PFS and OS trends compared to BR, but the executive admitted it may not become the first-line choice for CLL/SLL due to limited follow-up data and current treatment practices favoring covalent BTK inhibitors [34]. Summary by Sections 1. R/R MM: Focus on Dual/Triple Antibodies and TCE Therapies - Johnson & Johnson's BCMA/CD3+daratumumab therapy received FDA's "National Priority Voucher," reducing review time to 1-2 months, showing excellent efficacy in high-risk patients [7][15]. - IBI3003 from Innovent demonstrated an overall response rate (ORR) of 83.3% in high-risk patients, with a 100% minimal residual disease (MRD) negative rate in those achieving complete response (CR) [16]. - AstraZeneca's AZD0120 (BCMA/CD19 CAR-T) is projected to exceed $5 billion in sales, with a 100% ORR in treated patients [20][21]. 2. DLBCL: MSD ROR1 ADC Shows First-Line Potential - The MSD ROR1 ADC demonstrated a 24-month OS rate of 94% and a PFS rate of 84%, outperforming R-CHOP and Pola-CHP treatments [22][23]. - In high-risk populations, the ORR was 75% for patients with extramedullary disease (EMD), with a 100% ORR in the 1200 µg/kg dose group [23]. 3. CLL/SLL: Pirto May Not Become First-Line Choice - Pirto vs BR showed a 24-month PFS of 93.4% vs 70.7%, but the data is still immature, with a median follow-up of 28 months [25][27]. - The safety profile of Pirto indicated a 40% incidence of grade 3 or higher treatment-emergent adverse events (TEAEs), compared to 67.4% for BR [25][27].
