A Study to Assess the Effects of Savolitinib on the Pharmacokinetics of Digoxin, Rosuvastatin, Metformin, and Furosemide in Healthy Male Subjects

AstraZeneca6 enrolled

Overview

This study will assess the effects of savolitinib on the pharmacokinetics (PK) of substrates of human transporters digoxin (P-gp), rosuvastatin (OATP1B1/3), metformin (OCT2, MATE1/2K), and furosemide (OAT1/3) in healthy male subjects, performed at a single clinical unit.

This study will be performed at a single clinical unit. Subjects will be admitted to the clinical unit on Day -1 of Period 1 and Period 2. Subjects will have a washout period of 14 days between Period 1 and Period 2. Period 1: Subjects will recieve a single dose of a drug cocktail of 4 medications (digoxin Dose B, furosemide Dose C, metformin hydrochloride Dose D, and rosuvastatin Dose E). Period 2: Participants will receive savolitinib (Dose A) in combination with the drug cocktail of 4 medications as received in Period 1. The study will consist of 4 visits: Visit 1 (Enrollment): Following full written informed consent, subjects will be screened for eligibility. Visit 2 (Period 1: Treatment and Sample Collection Period): Each subject will be admitted to the clinical unit on Day -1 of Period 1, single dose of drug cocktail is administered on Day 1, and remain in clinical unit until Day 5 assessments. A washout period of 14 days is followed. Visit 3 (Period 2: Treatment and Sample Collection Period): Each subject will be admitted to the clinical unit on Day -1 of Period 2, single dose of savolitinib and drug cocktail is administered, and remain in clinical unit until Day 5 assessments. Visit 4 (Follow-up): Subjects will attend the clinical unit for a final Follow-up Visit 5 to 7 days post Day 5 in Period 2. Each subject will be involved in the study for 9 weeks including screening to final follow up.

History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the investigator or history of hypersensitivity to drugs with a similar chemical structure or class to savolitinib, or drug cocktail medications or their excipients. 10. Subject has clinical signs and symptoms consistent with Coronavirus disease (COVID-19), eg, fever, dry cough, dyspnea, sore throat, fatigue, or confirmed infection by appropriate laboratory test within the last 4 weeks prior to screening or on admission unless confirmed by a negative severe acute respiratory syndrome coronavirus 2 polymerase chain reaction test (SARS-CoV-2 PCR test). 11.
