Phase 1
Completed
Conditions
Healthy
Interventions
Drug: Placebo
Registration Number
NCT02217917
Lead Sponsor
GlycoMimetics Incorporated
Brief Summary

This is a 2 part study designed to provide an initial assessment on the safety, tolerability, and PK of rivipansel, following single ascending (Part 1) and multiple ascending dosing (Part 2) given subcutaneously with rHuPH20, in healthy subjects. Part 1 of the study will be conducted using a cross-over design while Part 2 of the study will be conducted using a parallel design.

  • History of hepatitis or positive testing for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb) or hepatitis C antibodies (HCV).
  • Unwilling or unable to comply with the Lifestyle Guidelines described in this protocol.
  • Subjects who are investigational site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the Investigator, or subjects who are Pfizer employees directly involved in the conduct of the study.
