Sutro Biopharma, a California based, clinical-stage company, announced initial safety data in ovarian cancer patients from its ongoing phase I study (NCT03748186) of STRO-002. The drug is a folate receptor alpha (FolRα)-targeting antibody-drug conjugate (ADC) and potent anti-tumor activity in preclinical endometrial cancer patient-derived xenograft (PDX) models.
