Study Endpoints
Primary Endpoints
Part A: Area under the plasma concentration-time curve from zero to infinity for cocktail parent compounds (midazolam, omeprazole and caffeine)
Blood samples are collected on Day -8 and Day 3 of Part A at pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 10, 12 and 24 hours post cocktail dose

To assess the effect of AZD1775 on the PK of probe substrates for CYP1A2 (caffeine), CYP2C19 (omeprazole), and CYP3A (midazolam)

Part A: Area under the plasma concentration-time curve from time zero to the time "t" of the last quantifiable concentration for cocktail parent compounds (midazolam, omeprazole and caffeine)
Blood samples are collected on Day -8 and Day 3 of Part A at pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 10, 12 and 24 hours post cocktail dose

To assess the effect of AZD1775 on the PK of probe substrates for CYP1A2 (caffeine), CYP2C19 (omeprazole), and CYP3A (midazolam)

Part A: maximum plasma drug concentration for cocktail parent compounds (midazolam, omeprazole and caffeine)
Blood samples are collected on Day -8 and Day 3 of Part A at pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 10, 12 and 24 hours post cocktail dose

To assess the effect of AZD1775 on the PK of probe substrates for CYP1A2 (caffeine), CYP2C19 (omeprazole), and CYP3A (midazolam)

Part B: dECG intervals (QTcF) for absolute values and time-matched change from baseline
dECGs are measured on Day -1, Day 1 and Day 3 of Part B at pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12 and 24 hours post AZD1775 dose

To assess the effect on QT interval corrected for heart rate (QTc) following multiple oral doses of AZD1775

Secondary Endpoints
Time to reach maximum plasma concentration for cocktail parent compounds (midazolam, omeprazole and caffeine)
Blood samples are collected on Day -8, and Day 3 of Part A at pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 10, 12 and 24 hours post dose
Terminal half-life for cocktail parent compounds (midazolam, omeprazole and caffeine)
Blood samples are collected on Day -8, and Day 3 of Part A at pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 10, 12 and 24 hours post dose
Elimination rate constant for cocktail parent compounds (midazolam, omeprazole and caffeine)
Blood samples are collected on Day -8, and Day 3 of Part A at pre-dose, 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 10, 12 and 24 hours post dose

Wee-1 kinase inhibitor AZD1775EXPERIMENTALTo evaluate the effect of multiple doses of AZD1775 on the PK of substrates for CYP3A (midazolam), CYP2C19 (omeprazole), CYP1A2 (caffeine) and to evaluate the effect of multiple doses of AZD1775 on QT interval
Interventions
NameTypeDescription
CYP1A2 (caffeine)DRUGIn Part A, Period 1, patients will be administered a 3 drug cocktail of caffeine, omeprazole and midazolam on Day -8 followed by a washout period of at least 7 but no more than 14 days. In Part A, Period 2, AZD1775 capsules will be administered orally, 225 mg bid, until steady state for 2.5 days (total of 5 doses) and administered together with the cocktail on the morning of Day 3.
CYP2C19 (omeprazole)DRUGIn Part A, Period 1, patients will be administered a 3 drug cocktail of caffeine, omeprazole and midazolam on Day -8 followed by a washout period of at least 7 but no more than 14 days. In Part A, Period 2, AZD1775 capsules will be administered orally, 225 mg bid, until steady state for 2.5 days (total of 5 doses) and administered together with the cocktail on the morning of Day 3.
CYP3A (midazolam)DRUGIn Part A, Period 1, patients will be administered a 3 drug cocktail of caffeine, omeprazole and midazolam on Day -8 followed by a washout period of at least 7 but no more than 14 days. In Part A, Period 2, AZD1775 capsules will be administered orally, 225 mg bid, until steady state for 2.5 days (total of 5 doses) and administered together with the cocktail on the morning of Day 3.
Kytril (granisetron)DRUGPatients should be administered Kytril (granisetron) 1 mg orally, under fasted conditions (-2 to 2 hours away from meals), 30 minutes prior to administration of the AZD1775 capsules with a small amount of water.
Wee-1 kinase inhibitor AZD1775DRUGMultiple doses of 225 mg AZD1775, (3 x 75 mg, printed capsules) administered orally. The drug class of AZD1775 is Wee-1 kinase inhibitor.
