Frequently asked questions about MGC028

What is MGC028 used for?

MGC028 is an investigational monoclonal antibody being studied for the treatment of advanced solid tumors. The Phase 1 trial is enrolling adults with advanced solid tumors, including NSCLC adenocarcinoma, cholangiocarcinoma, pancreatic carcinoma, and colorectal carcinoma. It is not approved for any indication and remains in clinical development.

What does MGC028 target?

MGC028 targets ADAM9, a protein that is part of the ADAM family of cell surface and secreted proteins. By binding ADAM9, MGC028 is designed to act against tumor cells that express this target. The Phase 1 study is biomarker selected, meaning participants are chosen based on the presence of the relevant biomarker.

Who is developing MGC028?

MGC028 is being developed by MacroGenics, Inc., a clinical-stage biopharmaceutical company. MacroGenics trades on the Nasdaq under the ticker symbol MGNX. The company is the sponsor of the ongoing Phase 1 trial of MGC028 in advanced solid tumors.

What phase is MGC028 in?

MGC028 is in Phase 1 clinical development. The single trial is currently recruiting participants and has an estimated enrollment of 124 adults. MGC028 is investigational and has not been approved by the FDA for any indication.

What clinical trials is MGC028 in?

MGC028 is being evaluated in one clinical trial, NCT06723236, titled A Study of MGC028 in Participants With Advanced Solid Tumors. The trial is a Phase 1, controlled study that is currently recruiting in the United States. It enrolls adults 18 years and older and does not include healthy volunteers.
