Study Description

Brief Summary

This study will be an open-label, fixed sequence study in healthy subjects (vasectomized males and females of non-childbearing potential), performed at a single study centre.

Condition or Disease	Intervention/Treatment	Phase
Healthy Volunteers (Intended Indication: Metastatic Patients With Triple Negative or HR+ Breast Cancer, or Hormone Sensitive Prostate Cancer)	Drug: Capivasertib Drug: Itraconazole	Phase 1

Detailed Description

The study will comprise:

A screening period of maximum 21 days;
A fixed sequence of 3 treatment periods: Treatment Period 1: Capivasertib only,

Treatment Period 2: Itraconazole pre-treatment (run-in) period, and Treatment Period 3:
