Analyses will be conducted between end of the treatment phase (week 12) and the post-discontinuation of treatment visit (week 16).
Secondary outcome [9] 295803 0
Investigation of safety and tolerability using adverse events (for example, changes in skin pigmentation)
Timepoint [9] 295803 0
Adverse events will be recorded at each visit (from week 2 to week 12) and comparisons will be made between minocycline and placebo to determine differences in the frequency of events.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be sequentially allocated to recieve a recruitment number. Recruitment numbers are listed on the medication bottles (which are identical in each arm) with both the clincian and participant being blind to treatment. The person responsible for the randomisation code is independent of the study interviews.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer permutated blocks are used to generate the randomisation sequence. Blocks include a 2X4 allocation of treatment arms.

Summary
Brief summary
This study aims to investigate minocycline as an adjunctive treatment for unipolar depression. Participants will receive 200 mg/day of minocycline or placebo for 12 weeks with improvements on the MADRS being the primary outcome. Secondary outcomes include potential improvements in functioning, quality of life and clincial impressions. Based on previous studies, minocycline should be well-tolerated for the duration of the study, however safety monitoring will also be reported as a secondary outcome.
