Basic Information

• Recruitment Status: COMPLETED

Brief Summary

This will be an open-label, randomised, 2 part (Part A and Part B), 2 treatment (savolitinib alone or in combination with famotidine), crossover study in healthy, non Japanese, male subjects, performed at a single study centre.

Detailed Description

Parts A and B will each have 2 Periods (Period 1 and Period 2) with a crossover design. Part B will be conducted only if results of Part A suggest a clinically meaningful effect of famotidine on savolitinib pharmacokinetics (PK) parameters. In both parts subjects will be randomly assigned 1:1 to receive one of the 2 treatment sequences: savolitinib alone first followed by crossover to the combination treatment of savolitinib+famotidine, or the reverse sequence. Subjects will be admitted for 4 days from one day before the first dose of the study drug and discharged 2 days after. There will be a washout period (no study treatment) of 14 days between the 2 Periods. The essential difference between the 2 parts is that in the combination treatment, famotidine will be administered 2 hours before savolitinib in Part A and 6 hours before savolitinib in Part B. A given subject will receive a total of 1 dose of famotidine and 2 doses of savolitinib during the study.

In this 2 part study, 16 subjects will be randomised in each part to ensure at least 14 evaluable subjects at the end of the last study period. If Part B is conducted, a total of 32 subjects overall are planned to be enrolled in the study. Additional subjects may be enrolled to ensure 14 evaluable subjects in each part if more than 2 subjects are deemed non evaluable.

Eligibility Criteria

Inclusion Criteria

• Provision of signed and dated written informed consent prior to any study specific procedures.
• Healthy, non-Japanese male subjects with suitable veins for cannulation or repeated venipuncture: male subjects aged 18 to 65 years (inclusive).
• Have a body mass index (BMI) between 18 and 30 kg/m2 inclusive; and weigh at least 50 kg and no more than 100 kg inclusive.
• Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBL) less than or equal to the upper limit of normal for the institution.
• Have a calculated creatinine clearance greater than 80 mL/min using the Cockcroft-Gault formula at screening.
• Provision of signed, written and dated informed consent for optional genetic/biomarker research. If a subject declines 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 this protocol.

Exclusion Criteria

• Subject that has at least 1 parent or grandparent (maternal or paternal) of Japanese ethnicity.
• Subjects who screen positive for Helicobacter pylori bacteria.
• History of any clinically significant disease or disorder which, in the opinion of the Principal Investigator (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.
• 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.
• Any clinically important illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of either study drug (savolitinib or famotidine).
• Planned in-patient surgery, dental procedure, or hospitalisation during the study.
• Any clinically important abnormalities in clinical chemistry, haematology, or urinalysis results, as judged by the PI.
• Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody, and human immunodeficiency virus (HIV) antibody.
• 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.

• Any clinically important abnormalities in rhythm, conduction or morphology of the 12 lead resting electrocardiogram (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, incomplete bundle branch block, or intraventricular conduction delay with QRS >110 ms. Subjects with QRS >110 ms but <115 ms are acceptable if there is no evidence of eg, ventricular hypertrophy or pre-excitation.
