GlycoMimetics to Present New Preclinical Data in Multiple Myeloma at AACR Annual Meeting 2017

ROCKVILLE, Md.--(BUSINESS WIRE)-- GlycoMimetics, Inc. (NASDAQ:GLYC) today announced that pre-clinical research demonstrating the potential of two of its drug candidates, GMI-1271 and GMI-1359, against multiple myeloma will be shared via an oral presentation at the American Association for Cancer Research (AACR) Annual Meeting 2017 in Washington, DC. The company and its collaborators at Washington University in St. Louis will highlight data on GMI-1271, an antagonist of E-selectin, and GMI-1359, a dual antagonist of E-selectin and CXCR4, showing anti-cancer activity in preclinical models of multiple myeloma.

The research demonstrated that:

  • In cell culture, GMI-1271 and, to a greater extent GMI-1359, reduced multiple myeloma cell adhesion to stromal cells and inhibited chemotaxis of multiple myeloma cells toward conditioned media.
  • The presence of GMI-1271 or GMI-1359 reduced stroma-induced drug resistance of multiple myeloma cells to carfilzomib and lenalidomide. In a preclinical model of multiple myeloma, combination therapy of GMI-1271 and lenalidomide profoundly delayed tumor growth.
  • Combination therapy of carfilzomib with GMI-1271 or GMI-1359 prolonged survival of mice with multiple myeloma over treatment with carfilzomib alone.

"Our results show a strong effect on cancer cells in combination with chemotherapy and importantly, are supportive of our ongoing Phase 1 clinical studies in multiple myeloma of GMI-1271 as well as our study of GMI-1359 in multiple cancers," said John Magnani, Ph.D., GlycoMimetics Senior Vice President and Chief Scientific Officer. "These results complement data from other preclinical studies and continue to build the rationale for our on-going clinical programs with both compounds."

Details of the AACR presentation include:

Abstract #5005—Muz, B.B., et al. "Inhibition of E-Selectin or E-selectin together with CXCR4 re-sensitizes multiple myeloma to treatment." Tuesday, April 4, 3:00-5:00 p.m. ET.

The AACR Annual Meeting 2017 takes place from April 1 to 5, at the Walter E. Washington Convention Center. Meeting abstracts are available at AACR's website.

GMI-1271 is currently being evaluated in an ongoing Phase 1/2 clinical trial as a potential treatment for acute myeloid leukemia (AML) and in a Phase 1 clinical trial in multiple myeloma. GMI-1359 is now in a Phase 1 clinical trial.
