TD-1473 formulation bridging & food effectTD-1473Subjects will receive, on Day 1 of each period, a single 100 mg oral dose of the tablet formulation of TD-1473 in the fed or fasted state, or the PIC formulation of TD-1473 in the fasted state, as part of a 3-period, crossover design.
TD-1473 without ItraconazoleTD-1473Subjects will receive a single 100 mg oral dose of the tablet formulation of TD-1473 in the fasted state on Day 1 of Period 1.
TD-1473 with ItraconazoleTD-1473Subjects will receive a single 100 mg oral dose of the tablet formulation of TD-1473 in the fasted state on Day 1 of Period 1. In Period 2, subjects will receive, in the fasted state, single oral doses of 200 mg itraconazole solution on Days -4 through 7 for a total of 11 days, with a single 100 mg oral dose of the tablet formulation of TD-1473 co-administered on Day 1.
TD-1473 with ItraconazoleItraconazoleSubjects will receive a single 100 mg oral dose of the tablet formulation of TD-1473 in the fasted state on Day 1 of Period 1.
