Zymeworks Inc is a clinical-stage company. It is dedicated to the discovery, development and commercialization of next-generation multifunctional biotherapeutics, initially focused on the treatment of cancer. The company's product candidate, ZW25, is a bispecific (dual-targeting) antibody being evaluated in an adaptive Phase 1 clinical trial, targeting two distinct domains of the human epidermal growth factor receptor 2, or HER2. Its design enables ZW25 to address patient populations with all levels of HER2 expression, including those with low to intermediate HER2-expressing tumors, who are otherwise limited to chemotherapy or hormone therapy.
