The Sponsor is developing the test medicine, AZD6094 (Savolitinib) for the potential treatment of cancer. Cancer is a condition where cells in a specific part of the body grow and reproduce uncontrollably, causing a growth called a tumour. The test medicine works to inhibit a pathway within the body which promotes tumours to grow and spread. The study involves radiolabelling (labelling the molecule with radioactive 14C) which is used to locate the molecule within the body.

The study will evaluate the absolute bioavailability of the test medicine (amount of the oral test medicine that enters the blood stream relative to the dose given into the vein), along with the mass balance (how much radioactivity can be recovered from the urine and faeces) and the rates and routes of elimination of [14C]savolitinib. It will also look to identify the breakdown products (metabolites) of the test medicine. The safety and tolerability of the test medicine will be assessed.

The study will consist of two parts, involving a minimum of eight healthy male volunteers. In Part one, following a high fat breakfast, volunteers will receive a single oral dose of the test medicine, followed by an intravenous infusion (solution into the vein) of radiolabelled test medicine. Volunteers will remain resident in the clinical unit until 72 hours post-oral dose.

There will then be a washout period of at least 14 days, after which the volunteers will return to the clinical unit for Part two. Volunteers will receive a single oral dose of radiolabelled test medicine as an oral solution. Blood, urine and faecal samples will be collected from volunteers whilst they are resident in the clinical unit for up to 168 hours postdose (Day 8). Volunteers will return for a follow-up visit at least 14 days after their last dose for safety assessments.

Mean resting corrected QT interval (QTcF) >450 msec on screening or pre-dose (Part 1 only) obtained from 3 ECGs or factors that may increase the risk of QTcF prolongation or any clinically important abnormalities in rhythm, conduction or morphology of resting electrocardiograms (ECGs), e.g., complete left bundle branch block, third degree heart block, second degree heart block, PR interval >250 msec.

8. Any factors that may increase the risk of QTcF prolongation such as chronic hypokalaemia not correctable with supplements, congenital or familial long QT syndrome, or family history of unexplained sudden death under 40 years of age in first-degree relatives or any concomitant medication known to prolong the QT interval and cause Torsade de Pointes.

9. Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody, and human immunodeficiency virus (HIV) antibody.

10. Known or suspected history of drug abuse, as judged by the investigator.

11. Has received another new chemical entity (defined as a compound which has not been approved for marketing; including radiolabelled chemical entity) within 90 days or five elimination half-lives, whichever is longer, of the first dosing date in this study. The period of exclusion lasts for 90 days or five elimination halflives after the final dose or 1 month after the last visit, whichever is the longest. Note: subjects consented and screened, but not administered IMP in this study or a previous Phase I study, are not excluded
