MacroGenics Doses First Patient In Phase 1 Study Of MGC030, Antibody-Drug Conjugate Directed Against Undisclosed Target, In Patients With Advanced Solid Tumors

MacroGenics, Inc. (NASDAQ:MGNX), a clinical-stage biopharmaceutical company focused on developing innovative antibody-based therapeutics for the treatment of cancer, today announced that the first patient has been dosed in the Phase 1 study of MGC030, a first-in-class antibody-drug conjugate (ADC) directed against an undisclosed target, in patients with advanced solid tumors.

The Phase 1, open-label, multi-center, dose-escalation, dose-optimization and cohort-expansion study of MGC030 is designed to characterize the safety, tolerability, pharmacokinetics (PK), immunogenicity and preliminary antitumor activity of MGC030, as well as explore biomarkers that may be associated with these endpoints. Participants with relapsed or refractory solid tumors that are unresectable, locally advanced, or metastatic, including urothelial, colorectal, gastric or gastroesophageal junction, esophageal, and pancreatic cancers, will be enrolled. The dose escalation portion of the study will enroll up to 54 participants with the potential to further expand enrollment at selected dose levels.
