Study Arms (4)

The DDI of GP681 and Rosuvastatin Calcium Tablets

EXPERIMENTAL

Subjects will receive a single dose of Rosuvastatin Calcium 10 mg on Day 1, then take a single doses of 40mg GP681, 10mg Rosuvastatin Calcium on Day 8.

Drug: GP681; Drug: Rosuvastatin

The DDI of GP681 and Digoxin Tablets

EXPERIMENTAL

Subjects will receive a single dose of Digoxin 0.25 mg on Day 1, then take a single doses of 40mg GP681, 0.25mg Digoxin on Day 15.

Drug: GP681; Drug: Digoxin

The DDI of GP681 and Itraconazole Capsules

EXPERIMENTAL

Subjects will receive a single dose of GP681 20mg on Day 1, then take Itraconazole 200 mg twice-daily on Day 22 and 200 mg once-daily on Day 23 through Day 36, and took a single dose of GP681 20 mg on Day 26.

Drug: GP681; Drug: Itraconazole

The DDI of GP681 and Oseltamivir Capsules

EXPERIMENTAL

Subjects will receive all three treatments in a crossover fashion according to the randomized sequence. The treatments were as follows: single oral administration of GP681 at 40 mg on day 1 in the fasted state; single oral administration of oseltamivir at 75 mg on day 1 and day 5in the fasted state, followed by repeated twice-daily administration of oseltamivir at 75 mg until day 5 after each meal; co-administration of GP681 at 40 mg and oseltamivir at 75 mg simultaneously on day 1 in the fasted state, followed by repeated twice-daily administration of oseltamivir at 75 mg until day5 after each meal. There was an at least 21-day washout interval between each treatment.

Drug: GP681; Drug: Oseltamivir
