F901318 Multiple Ascending Dose Study
Study Details
Study Description
Brief Summary
Double blind, placebo controlled, parallel group ascending dose study evaluating single and multiple (x8 days) dose levels of F901318 in groups of male healthy subjects with the objective of defining a dosing schedule for phase ll clinical trials. F901318, a novel and potent antifungal agent for the treatment of invasive aspergillosis, will be delivered intravenously in a range of dosing schedules driven by pharmacokinetic evaluation in real time. Safety and tolerability of those schedules will also be assessed.

Detailed Description
Double blind, placebo controlled, ascending single and multiple intravenous dose, sequential group study. This will be a study in two parts. In the first part, up to twenty four subjects will complete the study in up to 3 cohorts (Groups A to C), each group consisting of 8 subjects, six of whom will receive active compound and two will receive placebo for eight days. Each subject will be on study for approximately 7 weeks. Each subject will participate in one treatment cohort only, residing at the Clinical Research Unit (CRU) from Day -1 (the day before dosing) to Day 13 (120 hours post the last dose).
This first part (Part 1) will test doses already evaluated in the previous single ascending dose study (F901318-01-01-14, 0.25-4 mg/kg given over 4 hours). The dose levels for the study are expected to be 1.5, 3 and 4 mg/kg/day given as a four hour infusion once daily.
In the second part of the study (Part 2), doses higher than those previously evaluated may be studied and/or different dosing schedules designed to deliver a maximum tolerated dose over 24 hours. If a dose level higher than those previously studied is chosen, there will be an optional single dose studied initially for safety and pharmacokinetic profile (Part 2A), followed about 14 days later in another group of subjects by exposure at that same dose level over 8 consecutive days (Part 2B). These higher doses may be given in a once or twice daily dosing schedule. Six subjects will receive active compound and two will receive placebo in both the single dose and multiple dose cohorts. The single dose cohorts will receive study drug in a sentinel group design in which two subjects receive study drug (one active and one placebo) on the first day and the rest of the group one day later. There will be a review of safety data by the Principal Investigator and the Medical Monitor after the first two subjects have been dosed and before the last six subjects are dosed in each cohort in part 2A.
In Part 2, up to forty-eight subjects will complete the study in up to 6 cohorts (Part 2A, Groups D1 to F1, single day dosing, and Part 2B, Groups D2 to F2 eight days' dosing). Subjects in Parts 1 and 2B will be on the study for approximately 7 weeks and Part 2A for approximately 8 weeks. Each subject will participate in one treatment cohort only, residing at the Clinical Research Unit (CRU) from Day -1 (the day before dosing) to Day 6 (120 hours after the single dose in Parts 1 and 2A) and from Day -1 (the day before dosing) to Day 13 (120 hours after the first dose in Part 2B). The proposed total daily dose levels for Part 2 will be up to 10 mg/kg/day given either once daily or in two split daily doses. The duration of the infusions will be between 2 and 24 hours which may include a loading dose to achieve therapeutic plasma concentrations as quickly as possible.
All subjects will return for a post-study visit 8 to 10 days after the last dose of study medication.
