NEOK Bio

NEOK Bio is a Palo Alto-based clinical-stage biotechnology company developing bispecific antibody drug conjugates (ADCs) for solid tumors. Founded and led by physician-executive Mayank Gandhi and backed by Korean antibody specialist ABL Bio, NEOK launched from stealth in November 2025 with a $75 million Series A. Its dual-targeting approach binds two complementary tumor antigens at once, aiming to widen the therapeutic window and overcome the resistance and toxicity limits of conventional single-target ADCs. The company's two lead programs, NEOK001 (ROR1/B7-H3) and NEOK002 (EGFR/MUC1), both cleared FDA IND review in early 2026 and are headed into Phase 1 studies.
