Intervention/exposure

Description of intervention(s) / exposure
Cognitive Behavioural Therapy (CBT) will be administered once a week, over a period of 12 weeks

Antidepressant fluoxetine hydrochloride or a placebo tablet will be administered in conjunction with CBT over a period of 12 weeks. The starting dose of fluoxetine or placebo will be 1 capsule or 20mg, administered orally. The dose may be increased at week 5 of the study to a maximum dose of 2 capsules or 40 mg.

Each treatment session will last 45 to 50 minutes. Typically, an individual CBT session comprises 3 components. The first third of the session is devoted to reviewing the take-home practice activities and setting an agenda for the current session by reviewing mood, events, incidents or issues that have arisen during the previous week. The middle third of the session is devoted to the skill to be taught that week, linking it with any issues or incidents raised in the first third of the session. The final third of the session addresses issues that have been generated in the first third of the session, and plans are made for the next take-home practice activity.
It is anticipated that all therapists will attend fortnightly supervision sessions with senior clinicians. The fidelity of CBT treatment will be assessed throughout the trial to ensure that the treatment delivered by the trial therapists adheres to the CBT manual. Each CBT session will be recorded, and the de-identified recording will be stored on the OYHRC secure server. A random session from the course of therapy for each participant will be independently rated by an expert CBT practitioner using specifically designed scales for measuring CBT fidelity

Participants will commence on 1 tablet of fluoxetine 20 mg or 1 tablet of the placebo pill. The medication can be increased to fluoxetine 40 mg daily (or 2 placebo pills) if there has been a poor clinical response after the first 4 weeks. The medication will be prescribed by the treating doctor after the baseline visit has been completed and the participant has been randomised. The trial medications will be supplied on a 4-weekly basis by the RMH Royal Park Campus pharmacy, with a total of 3 dispensations per patient

Comparator / control treatment
Placebo will be administered as a control treatment instead of fluoxetine. Placebo capsules will be made of Microcrystalline Cellulose and matched in appearance to the fluoxetine medication (all manufacturing will be conducted under Good Manufacturing Practice-GMP). It will be administered orally and in conjunction with CBT over a period of 12 weeks. The starting dose will be 1 capsule or 20mg of placebo, which may be increased at week 5 of the study to a maximum dose of 2 capsules or 40 mg of placebo.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After the baseline assessment has been completed, the participant will be randomised to one of the two treatment groups. A randomisation list has been generated by an independent, unblinded statistician and passed onto the electronic database technician/designer. Therefore, allocation concealment is performed via central randomisation by a computer, which will then be inputted into the eCRF by the technician. Upon randomisation, an email will be sent directly to the pharmacy specifying whether the participant should be allocated fluoxetine or placebo. Participants will be randomised sequentially (within the applicable stratum based on site, age and gender information) as they become eligible for randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation will be enabled by computer generated numbers programmed into the electronic CRF (eCRF) by an independent statistician.The randomisation will be stratified by site, age and gender.
