nbe-002 in patients with advanced solid tumors

Conditions: Advanced Solid Tumor; Advanced Cancer; Triple Negative Breast Cancer

Summary: this first-in-human study will evaluate the recommended dose for further clinical development, safety, tolerability, anti-tumor activity, immunogenicity, pharmacokinetics and pharmacodynamics of nbe-002, a novel anti-ror1 antibody-drug conjugate, in patients with advanced solid tumors.
