Detaljerad beskrivning
This was a Phase I, double-blind, cross-over, single-dose study of the orally administered anti-orthopoxvirus compound, ST-246, to 12 healthy, fed volunteers between the ages of 18 and 50 years. Subjects were randomized such that 6 subjects received either ST-246 Form I (monohydrate) followed 10 days later after a wash-out period by Form V (hemihydrate), and 6 subjects received ST-246 Form V followed by Form I, as for the previous group.
Both forms of ST-246 were similar in the way they were manufactured. The only difference between Form I and Form V may be related to how it dissolves, and this may affect the way that it is absorbed in the human body. Information about any side-effects that may occur will also be collected in this study.

Aktiv komparator: Group ST-246 Form I (followed by Form V)
Each of six subjects receive a single oral 400 mg dose (2×200 mg) of ST-246 Form I (monohydrate) in the first intervention period, followed 10 days later (3 days post-treatment monitoring and 7 days wash-out period) in the second intervention period by a single oral 400 mg dose (2×200 mg) of ST-246 Form V (hemihydrate). Both forms of drug are orally administered within 30 minutes after a standard light meal consisting of 400-450 calories and approximately 25% fat. |
First Intervention is on Days 1 - 3, and includes 6 patients dosed once orally with ST-246 Form I (Arm 1), and 6 patients dosed once orally with ST-246 Form V (Arm 2).
Andra namn:
Second Intervention is on Days 11 - 13 (after a 3 day post-treatment monitoring and 7 day wash-out period) where the 6 patients previously given ST-246 Form I (Arm 1) are now dosed once orally with ST-246 Form V, and the 6 patients previously given ST-246 Form V (Arm 2) are now dosed once orally with ST-246 Form I.
