Brief Summary

This is a two-part, open-label, randomized, crossover study in healthy subjects (vasectomized males and women of non-childbearing potential), performed at 2 study centers

Detailed Description

Part 1 of the study will comprise:

• A screening period of maximum 28 days.
• Three treatment periods [Treatment A: Single oral dose of capivasertib in overnight fasted state, Treatment B:Single oral dose of capivasertib in fed state (high-fat, high-calorie breakfast) and Treatment C:Twice daily oral doses of rabeprazole for 3 days and a single dose on Day 1, and a single oral dose of capivasertib in fasted conditions] during which subjects will be resident from the morning of Day -1 (Day -4 for subjects receiving rabeprazole [Treatment C]) and discharged after the last pharmacokinetic (PK) sample collection, 48 hours after dosing of capivasertib of each treatment period.
• A final visit 7 to 14 days after the last capivasertib PK sample in Treatment Period 3.

Part 2 of the study will only be initiated if the findings from Part 1 show an interaction or are inconclusive. Part 2 of the study will comprise:

• A screening period of at least 28 days.
• Three treatment periods [Any 3 treatments: Treatment D:Single oral dose of capivasertib in overnight fasted state, Treatment E: Single oral dose of capivasertib in fed state (low-fat, low-calorie breakfast), Treatment F: Single oral dose of capivasertib in partially fasted conditions (food restricted from 2 hours prior to dosing until 1 hour after dosing), Treatment G: Single oral dose of capivasertib and single dose of famotidine in fasted condition and Treatment H: Twice daily oral doses of rabeprazole for 3 days (Days -3 to -1) and a single oral dose of capivasertib in fed state] during which subjects will be resident from the morning of Day -1 (Day -4 for subjects receiving rabeprazole [Treatment H]) and will be discharged after the last PK sample collection 48 hours after dosing of capivasertib of each treatment period.
• A final visit 7 to 14 days after the last capivasertib PK sample in Treatment Period 3.

The interim results from Part 1 indicated a potentially clinically relevant food interaction only and therefore Treatments D, E, and F will be studied in Part 2.
