Study Description

Brief 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.
Condition or disease Intervention/treatment Phase
Solid Tumors
Drug: Savolitinib
Drug: Rifampicin
Phase 1
Detailed 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).

15 Any intake of grapefruit, grapefruit juice, Seville oranges, Seville orange marmalade, or other products containing grapefruit or Seville oranges within 7 days of the first admission on Day -1.
16 Use of any prescribed or non-prescribed medication including antacids, analgesics (other than use of ibuprofen up to 72 hours before dosing day), herbal remedies, megadose vitamins (intake of 20 to 600 times the recommended daily dose) and minerals during the 2 weeks before the first administration of the IMP or longer (5 times the half-life) if the medication has a long half-life. No medications known to prolong the QT/QTc interval and cause TdP are allowed.
17 Positive screen for drugs of abuse, cotinine (nicotine) and/or alcohol at screening and at admission to the Study Centre (Day -1 [Period 1] and Day 14 [Period 2]) to the Study Centre.
18 History of severe allergy/hypersensitivity or ongoing clinically important allergy/hypersensitivity, as judged by the PI.
19 History of severe allergy/hypersensitivity or ongoing clinically important allergy/hypersensitivity, as judged by the PI or history of hypersensitivity to drugs with a similar chemical structure or class to savolitinib or rifampicin.
20 Plasma donation within 1 month of screening or any blood donation/blood loss > 500 mL during the 3 months prior to screening.
21 Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the first administration of IMP in this study. The period of exclusion begins 3 months after the final dose or 1 month after the last visit whichever is the longest.
Note: subjects consented and screened, but not enrolled in this study or a previous phase I study, are not excluded.
22 Involvement of any AstraZeneca, Parexel or study site employee or their close relatives 23 Subjects who have previously received savolitinib. 24 Judgment by the PI that the subject should not participate in the study if they have any ongoing or recent (i.e., during the screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions, and requirements.
25 Subjects who are vegans, vegetarians or have medical dietary restrictions and who are lactose intolerant.
26 Subjects who cannot communicate reliably with the PI. 27 Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
28 Subjects who wear soft contact lenses, unless the subject is prepared to refrain from wearing soft lenses throughout Period 2 until after the last PK sample collection in Period 3.
