NEOK001 is a first-in-class bispecific ADC designed to target B7-H3 and ROR1, two surface proteins highly expressed in cancer cells. NEOK002 is a novel bispecific ADC targeting EGFR epidermal growth factor receptor (EGFR) and MUC1 (Mucin 1)-expressing solid tumors. Each Phase 1 study is evaluating the safety, tolerability, and efficacy of these candidates in patients with cancers that co-express these targets. Both candidates enter the clinic on a foundation of promising preclinical studies in which they have demonstrated superior in vivo efficacy in solid tumors compared to traditional monovalent ADCs.

"Advancing two ADC programs from preclinical development to first-in-human dosing in such a short time underscores the operational efficiency and execution capabilities of our team," said Mayank Gandhi, MD, CEO of NEOK Bio. "Our novel bispecific ADC approach holds significant promise for unlocking new therapeutic value for patients with hard-to-treat solid tumors who need more effective treatment options."

Initial clinical data from both Phase 1 studies are expected in 2027.
