AlphaGen Therapeutics to Present Preclinical Studies of Two Next-Generation Alpha Therapies at AACR 2026
SHANGHAI, April 20, 2026 /PRNewswire/ -- AlphaGen Therapeutics (AlphaGen), a biopharmaceutical company that focuses on developing next-generation targeted alpha radiotherapies, today announced that it will present preclinical data on two advanced radiopharmaceutical programs at the 2026 Annual Meeting of the American Association for Cancer Research (AACR), is being held in San Diego, California, from April 17–22.
[212Pb]Pb-AG1002 is a next-generation non-agonist SSTR2-targeting alpha radiopharmaceutical. In preclinical studies, the compound demonstrated high binding affinity and a superior tumor-to-kidney (T/K) ratio compared to agonist radioligands. It showed robust tumor growth inhibition and survival benefit across multiple models with a very favorable safety profile.
[212Pb]Pb-AG1206 is a novel FAP-targeted alpha radioligand based on a macrocyclic peptide scaffold with picomolar binding affinity. The compound has rapid tumor accumulation and renal clearance, giving rise to high T/K ratio. It showed strong anti-tumor activity in multiple preclinical tumor models. Consistent with preclinical observations, patient imaging IIT showed strong tumor uptake and clean tissue background.
"We have developed a robust pipeline of novel and differentiated targeted alpha radiotherapies. We are pleased to showcase our exciting progress in two such programs at AACR Annual Meeting 2026." said Dr. Mai-Jing Liao, CEO of AlphaGen Therapeutics. "The data to be presented underscore our commitment to advancing next-generation targeted alpha therapies and delivering significant improvements for patients with difficult-to-treat tumors."
