Trial design

64 participants in 4 patient groups

Cohort 1

Experimental group

Description:

Single dose of 500mg deferiprone or placebo administered via intravenous infusion. First 2 subjects to enroll: 1 will be randomized to receive deferiprone and the other to receive placebo. Next 14 subjects enrolled: 13 will be randomized to receive deferiprone and 1 to receive placebo.

Treatment:

Drug: Placebo

Drug: Deferiprone

Cohort 2

Experimental group

Description:

Single dose of 1000mg deferiprone or placebo administered via intravenous infusion and oral solution. Randomization will be done for all 16 subjects at the same time: 14 will be randomized to receive deferiprone and 2 to receive placebo. Subjects enrolled to cohort 2 will receive an oral dose of deferiprone.

Treatment:

Drug: Placebo

Drug: Deferiprone

Cohort 3

Experimental group

Description:

Single dose of 1500mg deferiprone or placebo administered via intravenous infusion. Randomization will be done for all 16 subjects at the same time, 14 will be randomized to receive deferiprone and 2 to receive placebo.

Treatment:

Drug: Placebo

Drug: Deferiprone

Cohort 4

Experimental group

Description:

Single dose of 2000mg deferiprone or placebo administered via intravenous infusion. First 2 subjects to enroll: 1 will be randomized to receive deferiprone and the other to receive placebo. Next 14 subjects enrolled: 13 will be randomized to receive deferiprone and 1 to receive placebo.

Treatment:

Drug: Placebo
