Brief Summary

This study will be an open label, 2 period, fixed sequence study in healthy male subjects, performed at a single study center in the Unites States of America. The purpose of this study is to evaluate the effect of savolitinib on the PK of midazolam, a known cytochrome P450 (CYP) 3A substrate.

Detailed Description

This study is designed as an open-label, 2 treatment period, fixed sequence study in healthy male subjects, performed at a single study center.

The study will comprise:

• A screening period of maximum 28 days;
• Two treatment periods:

Treatment Period 1 consists of 5 days (Study Days -1 to 4), starting with admission to the Study Center on Study Day -1, dosing of midazolam alone on Study Day 1 and ending on Study Day 4, after a 3 day washout period.

Treatment Period 2 consists of 2 days (Study Days 5 and 6), with administration of midazolam in combination with savolitinib on Study Day 5. Subjects will be discharged from the Study Center on Study Day 6, after the last PK sample is collected.

• The Follow up Visit will occur at least 14 days (Study Day 19 or after) after the administration of savolitinib in Treatment Period 2.
• Subjects will be admitted to the Study Center on Study Day -1, prior to the evening meal the night before dosing with midazolam alone (Study Day 1) and will stay in house until at least 24 hours after dosing with midazolam in combination with savolitinib (Study Day 5). Subjects will thus be discharged on Study Day 6, after the last PK sample has been collected.

Each subject will be involved in the study between 21 and approximately 48 days.

Eligibility Criteria

Inclusion Criteria

1. Provision of signed and dated, written informed consent prior to any study specific procedures.

2. Healthy male subjects, aged 18 - 65 years (inclusive) , with suitable veins for cannulation or repeated venipuncture.

3. Have a body mass index (BMI) between 18 and 35 kg/m2 inclusive and body weight greater than 50 kg and no more than 100 kg.

4. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and Total Bilirubin (TBL) less than or equal to upper limit of normal for the institution at screening.

5. Have a calculated creatinine clearance (CrCL) greater than 80 mL/min using the Cockcroft-Gault formula at screening.

6. Provision of a signed, written and dated informed consent for optional genetic/biomarker research. If a subject decline to participate in the genetic component of the study, there will be no penalty or loss of benefit to the subject. The subject will not be excluded from other aspects of the study described in the protocol..

Exclusion Criteria

1. Healthy subjects of Japanese ethnicity and any healthy subject that has 1 parent or grandparent (maternal or paternal) of Japanese ethnicity.

2. History of any clinically significant disease or disorder which, in the opinion of the PI, may either put the volunteer at risk because of participation in the study, or influence the results or the volunteer's ability to participate in the study.

3. History or presence of gastrointestinal (GI), hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.

4. Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of IMP.

5. Planned in-patient surgery, dental procedure or hospitalizing during the study.

6. Any clinically significant abnormalities in clinical chemistry, hematology, or urinalysis results, as judged by the PI.

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

8. Abnormal vital signs, after 5 minutes supine rest, defined as any of the following:

(1) Systolic BP < 90 mmHg or ≥ 140 mmHg (2) Diastolic BP < 50 mmHg or ≥ 90 mmHg (3) Heart rate < 45 or > 85 beats per minute. 9 Any clinically significant abnormalities in rhythm, conduction or morphology of the 12-lead resting ECG that may interfere with the interpretation of QTc interval changes.

These include healthy subjects with any of the following:

1. Abnormal ST-T-wave morphology, particularly in the protocol defined primary lead (V2) or left ventricular hypertrophy.

2. PR interval shortening < 120 ms (PR > 110 ms but < 120 ms is acceptable if there is no evidence of ventricular pre-excitation).

3. PR interval prolongation (> 200 ms). Intermittent second (Type 1 second degree block [Wenckebach Phenomenon] while asleep is not exclusive) or third degree atrioventricular (AV) block, or AV dissociation.

4. Persistent or intermittent complete bundle branch block (BBB), incomplete bundle branch block (IBBB), or intraventricular conduction delay (IVCD) with QRS > 110 ms. Subjects with QRS > 110 ms but < 115 ms are acceptable if there is no evidence of e.g., ventricular hypertrophy or pre-excitation.

5. Mean resting correct QT interval (QTcF) > 450 ms for men on screening obtained from 3 ECGs or history or factors that may increase the risk of QTcF prolongation such as chronic hypokalemia 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 (TdP).

20 Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the administration of IMP in this study. The period of exclusion begins 3 months after the final dose or one month after the last visit, whichever is the longest.

Note: subjects consented and screened, but not randomized in this study or a previous phase I study, are not excluded.
