Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The Alfred Clinical Trials Pharmacy will perform trial randomisation, allocate, and dispense treatment. Study participants and research staff will remain blind to the intervention. A designated senior staff member who is not involved in the conduct of the study will facilitate unblinding due to any adverse event. Participants will receive notification of their results after the study is completed. Each participant will have a sealed opaque envelopes with their arm allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants who pass screening will be assigned by a permuted block 1:1 randomisation to be allocated to one of the two study arms
Masking / blinding

Efficacy
Statistical methods / analysis
Data will be collated, cleaned and validated using programmed edit checks, and stored in a secure database that will be locked to the Biostatistician and the Principal Investigators prior to reaching the recruitment target and analysis of the primary endpoint. This primary analysis will take place after all participants, apart from those who may have withdrawn, have had their final assessments. All randomised participants will be included in the statistical analysis (i.e., intention-to-treat) for primary and secondary outcomes
The primary analyses will compare, using the paired samples t-test:
1. The average of daily total DRSP scores for both the luteal and follicular phases between the pre-treatment (months 1 and 2) and treatment (months 3, 4 and 5) phases
2. The average of the total MADRS scores for both the luteal and follicular phases between the pre-treatment (months 1 and 2) and treatment (months 3, 4 and 5) phases
3. The average of the total DASS-21 scores for both the luteal and follicular phases between the pre-treatment (months 1 and 2) and treatment (months 3, 4 and 5) phases.

Summary
Brief summary
PMDD is a common condition that causes significant distress and disruption to daily life. The treatment options for PMDD are limited, however, newer forms of COCPs are becoming available and investigation of its efficacy is urgently needed. Moreover, no study to date has directly compared the efficacy of the first-line treatment options for PMDD. The proposed study aims to investigate whether nomegestrol acetate/17-beta estradiol (Zoely) or sertraline (Zoloft) is more effective in reducing symptoms of PMDD.
