Biocytogen Pharmaceuticals , a global biotech company specializing in antibody and ADC therapeutic discovery, announced that IDEAYA Biosciences , focused on precision oncology, has secured an exclusive worldwide license for Biocytogen’s B7H3/PTK7 bispecific ADC (BsADC) program, IDE034, and designated it as a development candidate.
Dr. Yuelei Shen, CEO of Biocytogen, expressed enthusiasm for IDEAYA’s decision to license IDE034, which incorporates Biocytogen’s proprietary topoisomerase linker-payload, noting it as a validation of the RenLite® platform and a promising step toward treatments for solid tumors. IDEAYA’s CSO, Dr. Michael White, highlighted IDE034's potential as a first-in-class B7H3/PTK7 topo-I-payload BsADC, demonstrating significant tumor regression in preclinical models, particularly in lung, colorectal, and head and neck cancers. IDE034 may be used as a monotherapy or combined with IDEAYA's PARG inhibitor, IDE161.
IDEAYA aims for an IND submission to the FDA in 2025 for IDE034, following the completion of preclinical studies. Under the licensing agreement, Biocytogen will receive up to $406.5 million in fees, including up to $100 million in milestone payments, plus royalties on net sales.
