Pfizer Announces Enrollment Of First Patient In Phase 3 Trial In Sickle Cell Disease

RESET Trial to Assess Effectiveness and Safety of Rivipansel (GMI-1070) in the Treatment of Vaso-Occlusive Crisis in Hospitalized Individuals with Sickle Cell Disease

NEW YORK--(BUSINESS WIRE)-- Pfizer Inc. (NYSE: PFE) today announced that the first patient has been enrolled in the RESET (Rivipansel: Evaluating Safety, Efficacy and Time to Discharge) study – a Phase 3 clinical trial assessing the efficacy and safety of rivipansel for the treatment of vaso-occlusive crisis in hospitalized individuals with sickle cell disease who are six years of age or older.

Sickle cell disease is one of the most prevalent genetic disorders in the U.S. It is a rare and debilitating chronic disease with lifelong clinical impact and reduced life expectancy; life expectancy is 48 years for females and 42 years for males with sickle cell disease. There are more than 100,000 people in the U.S. living with sickle cell disease1, and many of them experience multiple vaso-occlusive crises each year. These painful crises result in more than 75,000 hospitalizations per year in the U.S., with an average hospital stay of approximately six days.

“Scientific innovation cannot forge ahead without the patients that are willing to work with the scientific community by participating in clinical trials,” said Sonja L. Banks, president and chief operating officer of the Sickle Cell Disease Association of America. “Patients should speak with their healthcare providers if they are interested in learning more about how to participate in a trial.”

About the RESET Trial

This phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group study is planning to enroll at least 350 people with sickle cell disease, aged six and older who are hospitalized for a vaso-occlusive crisis and will evaluate the efficacy and safety of treatment with rivipansel. Study participants must be receiving treatment with intravenous opioids for their vaso-occlusive crisis and must be able to receive the first dose of study drug within 24 hours of initiation of intravenous opioid therapy.

The primary endpoint for the study will be time to readiness-for- discharge. Key secondary endpoints will include time to discharge, cumulative IV opioid consumption and time to discontinuation of IV opioids.

“We are pleased to enroll the first patient in the RESET trial, which will further our understanding of the potential role of rivipansel for the treatment of painful crises in patients with sickle cell disease,” said Brenda Cooperstone, MD, vice president and medicine team lead, Rare Diseases, Global Innovative Pharmaceuticals Business, Pfizer Inc. “Pfizer has a deep history in researching and bringing to market therapies for hematologic rare diseases and is committed to working to find innovative solutions to the sickle cell patient community’s unmet needs.”

About Rivipansel

Rivipansel (GMI-1070) is an investigational pan-selectin inhibitor. Selectins are a family of molecules believed to play a key role in regulating cellular interactions within blood vessels. Rivipansel is not a narcotic or a pain medication.

The intense pain associated with sickle cell vaso-occlusive crisis is believed to be due to local tissue ischemia consequent upon blockage occurring in microvascular beds and capillaries. This results from occlusion or clogging of vessels with sickled red blood cells (which become rigid and inflexible when sickled) and subsequent, selectin-driven adhesion of white blood cells (leukocytes) to the inner wall of the blood vessel (endothelium) and the recruitment of platelets; events which collectively restrict blood flow.

In 2011, Pfizer entered into a worldwide license agreement with GlycoMimetics (NASDAQ: GLYC) for the development and, if approved by applicable regulatory authorities, commercialization of rivipansel. GlycoMimetics was responsible for development up to phase 2 and Pfizer will be responsible for all future clinical development of rivipansel.

Rivipansel has received Orphan Drug and Fast Track status from the U.S. Food and Drug Administration (FDA), and this study is being conducted under a Special Protocol Assessment (SPA), in agreement with the FDA.
