A Study in Healthy Subjects to Assess the Pharmacokinetics of Savolitinib When Administered Alone and in Combination With Rifampicin

2019-10-15 11:11:31 | BioPortfolio

Summary

This is a phase I, open-label, 3 treatment period, fixed-sequence study in healthy non-Japanese vasectomized male subjects, aged 18 to 55 years or healthy non-Japanese male subjects over 45 to 55 years old, performed at a single study centre. Treatment Period 1 will establish the single dose pharmacokinetic (PK) profile of savolitinib. Dosing of daily rifampicin during Treatment Period 2 will result in maximal induction of the CYP450 enzymes including CYP3A4. Treatment Period 3 will then establish the single dose PK profile of savolitinib under maximum CYP450 induction conditions. Comparison of the PK profile of savolitinib between Treatment Period 1 and Treatment Period 3 will quantify the effect of CYP450 enzyme induction.

Description

The treatment starts with a single dose of savolitinib (Treatment Period 1), followed by a washout period at least of 14 days after savolitinib dosing and before the start of Treatment Period 2, followed by rifampicin administration for 5 days (Treatment Period 2), and lastly, a combination of savolitinib + rifampicin (Treatment Period 3). Overall, all subjects will receive 2 single doses of 600 mg savolitinib and 7 daily doses of 600 mg rifampicin. Subjects will be resident in the study centre when receiving study drug administrations (savolitinib [Treatment Period 1], rifampicin [Treatment Period 2] and savolitinib+rifampicin [Treatment Period 3]). Subjects are required to fast overnight before each dosing day. Rifampicin will be administered 1 hour before breakfast with 240 mL water. The subjects will need to complete high-fat, high calorie breakfast before administration of savolitinib in Treatment Period 1, Day 1 (Study Day 1) and Treatment Period 3 Day 1 (Study Day 20).

Medical and Biotech [MESH] Definitions

An alkylating agent of value against both hematologic malignancies and solid tumors.

An internationally recognized set of published rules used for evaluation of cancer treatment that define when tumors found in cancer patients improve, worsen, or remain stable during treatment. These criteria are based specifically on the response of the tumor(s) to treatment, and not on the overall health status of the patient resulting from treatment.

A smooth, solid or cystic fibroepithelial (FIBROEPITHELIAL NEOPLASMS) tumor, usually found in the OVARIES but can also be found in the adnexal region and the KIDNEYS. It consists of a fibrous stroma with nests of epithelial cells that sometimes resemble the transitional cells lining the urinary bladder. Brenner tumors generally are benign and asymptomatic. Malignant Brenner tumors have been reported.

A complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors.

A group of methylazirinopyrroloindolediones obtained from certain Streptomyces strains. They are very toxic antibiotics used as ANTINEOPLASTIC AGENTS in some solid tumors. PORFIROMYCIN and MITOMYCIN are the most useful members of the group.
