Primary outcome [1] 5642 0
To evaluate the safety and pharmacokinetics of FBS0701
Timepoint [1] 5642 0
Safety assessments and blood sampling for pharmacokinetic analysis will be preformed whilst patients are confined in the clinical facility for 24 hours, followed by visits at 36, 48 and 72 hours following dosing.
Secondary outcome [1] 241526 0
To determine dose-proportionality of ascending doses of FBS0701 by frequent blood sampling and urine collection, and pharmacokinetic analyses. Thirteeen blood samples will be taken during the first 12 hours following dosing on Day 1 of the study. Blood samples will then be taken every 12 hours to 48 hours following dosing, and then a final sample on Day 4 of the study. A continuous urine collection for 24 hours will occur following dosing.
Timepoint [1] 241526 0
For 72 hours post-dose
Secondary outcome [2] 241527 0
To characterise pharmacodynamics of FBS0701 by measuring urinary iron and magnesium.
Timepoint [2] 241527 0
For 72 hours post-dose
