Y-mAbs Presents Translational Pharmacokinetics of CD38-SADA from Pretargeted RIT Platform at 2025 American Association for Cancer Research (AACR) Annual Meeting

Core Insights - Y-mAbs Therapeutics, Inc. presented preclinical and translational pharmacokinetics (PK) data of CD38-SADA at the 2025 AACR Annual Meeting, focusing on its potential for cancer treatment [1][2] Group 1: Presentation Details - The poster titled "Preclinical and translational pharmacokinetic (PK) modeling of the self-assembling and disassembling (SADA) bispecific fusion protein CD38-SADA for first-in-human (FIH) pretargeted radioimmunotherapy (PRIT)" was presented, detailing plasma concentrations of CD38-SADA in animal models [2][5] - The presentation took place on April 27, 2025, from 2:00 p.m. to 5:00 p.m. CT at Poster Section 25 [5] Group 2: Research Findings - The study characterized the concentration- and time-dependent equilibrium between CD38-SADA tetramers and monomers, with the model showing that low molecular weight CD38-SADA monomers cleared from plasma 20 times faster than the tetramers [3] - The preclinical PK model provided insights into the circulating levels of CD38-SADA protein in vivo, which informed the design and initial dosing regimen of the first-in-human Phase 1 Trial 1201 [4] Group 3: Company Overview - Y-mAbs is a commercial-stage biopharmaceutical company focused on developing novel radioimmunotherapy and antibody-based therapeutic products for cancer treatment [6] - The company's product pipeline includes DANYELZA®, the first FDA-approved treatment for relapsed or refractory high-risk neuroblastoma [6] Group 4: CD38-SADA PRIT Technology - CD38-SADA is a bispecific fusion protein that binds to CD38 and Lu-DOTA, facilitating a two-step pre-targeted radioimmunotherapy process [7][8] - The technology has shown robust anti-tumor efficacy in preclinical studies and is currently being investigated in adults with relapsed, progressive, or refractory non-Hodgkin lymphoma [8]
