Frequently asked questions about GPC-100

What is GPC-100 used for in multiple myeloma?

GPC-100 is being developed for stem cell mobilization in patients with multiple myeloma who are undergoing autologous stem cell transplant. It is studied in combination with propranolol, with and without G-CSF, to help move stem cells from the bone marrow into the bloodstream for collection.

Who is developing GPC-100?

GPC-100 is being developed by Exicure, Inc., which trades on the Nasdaq under the ticker XCUR. Exicure is the sponsor of the clinical program evaluating GPC-100 in multiple myeloma.

What phase is GPC-100 in?

GPC-100 is in Phase 2 clinical development. The Phase 2 study in multiple myeloma has been completed. GPC-100 is investigational and has not been approved by the FDA for any indication.

What clinical trials is GPC-100 in?

GPC-100 has been evaluated in one clinical trial, NCT05561751, a Phase 2 study titled "Ph2, Study to Assess the Safety and Efficacy of GPC 100 and Propranolol With and Without G-CSF for the Mobilization of Stem Cells in Patients With Multiple Myeloma Undergoing Autologous Stem Cell Transplant." The trial enrolled 30 participants in the United States and is completed.

What does the GPC-100 Phase 2 trial involve?

The Phase 2 trial NCT05561751 assessed GPC-100 and propranolol, with and without G-CSF, for stem cell mobilization in patients with multiple myeloma undergoing autologous stem cell transplant. It was a controlled, randomized study that enrolled 30 participants aged 18 years and older in the United States.
