Frequently asked questions about GPC-100

What is GPC-100 used for in multiple myeloma?

GPC-100 is an investigational small molecule being studied in multiple myeloma. It is being evaluated for its ability to mobilize stem cells in patients with multiple myeloma who are undergoing autologous stem cell transplant. The drug is studied in combination with propranolol, with or without G-CSF.

Who is developing GPC-100?

GPC-100 is being developed by Exicure, Inc., a biopharmaceutical company. Exicure is listed on the stock exchange under the ticker symbol XCUR. The company is conducting clinical research to evaluate the safety and efficacy of GPC-100 in patients with multiple myeloma.

What phase is GPC-100 in?

GPC-100 is in Phase 2 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The Phase 2 study of GPC-100 has been completed, and the drug remains under clinical investigation for its potential use in multiple myeloma.

What clinical trials is GPC-100 in?

GPC-100 has been studied in a Phase 2 clinical trial registered as NCT05561751. This trial assessed the safety and efficacy of GPC-100 and propranolol, with and without G-CSF, for stem cell mobilization in patients with multiple myeloma undergoing autologous stem cell transplant. The trial was conducted in the United States and enrolled 30 participants.

Is GPC-100 the same as other drugs?

GPC-100 is a distinct investigational small molecule. It is being studied in combination with propranolol and G-CSF for stem cell mobilization in multiple myeloma. No alternative names for GPC-100 have been reported in the clinical trial information.
