Study of Intravenous GMI-1070 in Adults With Sickle Cell Disease - Full Text View

Purpose

This Phase 1/Phase 2 study will evaluate GMI-1070, a pan-selectin inhibitor, in adults with stable sickle cell disease. The study will assess safety, pharmacokinetics, and microvascular effects of intravenous GMI-1070 in the outpatient setting.

Primary Outcome Measures:

Safety as Measured by the Number of Participants With Adverse Events [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Total Plasma Clearance [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
Volume of the Central Compartment [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
Intercompartmental Clearance [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
Volume of the Peripheral Compartment [ Time Frame: 48 hours ] [ Designated as safety issue: No ]

Other Outcome Measures:

Blood Flow and Biomarkers of Adhesion [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
As an exploratory outcome mean change in microvascular blood flow from baseline to each time point was measured. Microvascular blood flow was also measured as microFI, perfused vessel density, and RBC velocity.
