Study Assessing Pharmacokinetics and Bioavailability of Three Novel Triazine Compounds

100 mcg Carbon-14 radio labeled WR826647 at an exposure no greater than 250 nCi per dose, administered both IV (bolus) and PO with a six half-life wash-out period between IV and PO administration. Interim analyses will be done at Day 14 following the IV dosing groups in order to assess half-lives of the three compounds to ensure the wash-out period between IV and PO dosing is at least six half-lives long.

100 mcg Carbon-14 radio labeled WR909388 at an exposure no greater than 250 nCi per dose, administered both IV (bolus) and PO with a six half-life wash-out period between IV and PO administration. Interim analyses will be done at Day 14 following the IV dosing groups in order to assess half-lives of the three compounds to ensure the wash-out period between IV and PO dosing is at least six half-lives long.
