Patient Information

GlycoMimetics has reported results in its Phase 2 clinical trial studying its lead investigational drug GMI-1070 in vaso-occlusive crisis (VOC) of sickle cell disease.

About Sickle Cell Disease

Sickle cell disease is one of the most prevalent genetic disorders, affecting between 90,000 and 100,000 people in the U.S. alone. It is a chronic condition with substantial illness and death, responsible for more than 70,000 hospitalizations per year in the U.S. One of the most debilitating effects of sickle cell disease is vaso-occlusive crisis (VOC), where changes in blood protein cause red blood cells to become rigid and stick inside small blood vessels.  This causes blockages in blood flow and results in pain, which can require medical care and hospital stays for pain medication. Other medical problems can also occur during vaso-occlusive crisis, which can complicate treatment and lead to longer hospital stays.

GMI-1070 for Treatment of Vaso-occlusive Crisis of Sickle Cell Disease

The first potential treatment use for GMI-1070, the lead investigational drug candidate in the GlycoMimetics pipeline, may be in “vaso-occlusive crisis of sickle cell disease.” GMI-1070 is intended to treat vaso-occlusive crisis by reducing the cell adhesion and inflammation that is believed to contribute to blocking blood flow. GlycoMimetics has begun to evaluate if this may reduce the pain experienced by individuals during sickle cell crisis and shorten their time in the hospital. GlycoMimetics, along with its partner Pfizer, is also studying whether this may reduce other medical problems that result from blood flow blockages.

GMI-1070 has received Orphan Drug status and Fast Track status from the U.S. Food and Drug Administration (FDA), which may lead to speedier delivery to people living with sickle cell disease, if the treatment is found to be effective.

In January 2013, GlycoMimetics, Inc. announced it had completed enrolling patients in a Phase 2 sickle cell disease trial with GMI-1070.  GlycoMimetics enrolled 76 patients ages 12 to 60 at 22 trial sites in the United States and Canada. The company reported topline data from the trial in April 2013. In this trial, patients treated with GMI-1070 experienced reductions in time to reach resolution of VOC, length of hospital stay and use of opioid analgesics for pain management, in each case as compared to patients receiving placebo.
