We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
The investigational medicinal product (study medication) is F03 and the comparator is F03- matching placebo. F03 will be in the form of capsules in 5 mg strength.
Dose administered in each cohort will be as follows:
Cohort 1: F03 5mg or placebo once daily
Cohort 2: F03 5mg or placebo twice daily
Duration of administration: 8 weeks.
Mode of administration: oral capsule
Adherence of study drug administration will be checked at each visit (Baseline, Weeks 1, 2, 4, 6 and 8) through the study diary cards that the participants are required to complete and study medication returns.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The study will be stratified by Centre only and a randomisation list will be prepared for each centre. A randomised block design will be used for each randomisation list. The randomisation number will be used for the medication kits and the numbering system for the case report form. An independent statistician will be assigned to prepare the final randomisation list.
This study is double - blind; therefore the Sponsor personnel, Investigator, site staff and patient will not know which treatment has been assigned.
If an emergency treatment code break is required then the Sponsors Medical Monitor and the site pharmacist will have access to the treatment assignment for each randomisation number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An independent statistician will be assigned to prepare the final randomisation list. The randomisation list will be produced by using a randomisation table created by computer software (namely SAS version 9.2).
