Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Pregnant women will be recruited while attending a routine antenatal visit. The research nurse will ask eligible women to participate, explain the trial and obtain informed consent, collect baseline data and ask women to self-collect a vaginal swab. Women who are culture positive for Candida will be randomised to receive active treatment with clotrimazole or no treatment and the screening result is not revealed. The women randomised to clotrimazole treatment will be notified by phone by a research nurse. A central pharmacy will be responsible for dispensing the study medication which will be sent to participants by mail from the coordinating centre. This approach has been acceptable and successful in a pilot study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule will be prepared by a researcher not involved with treatment allocation, and will use random permuted blocks and 1:1 randomisation.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Intervention assignment
Other design features
We will use a prospective, randomised, open-label, blinded-endpoint (PROBE) study design. Here (as in our pilot study) the strict randomisation and allocation concealment procedures are maintained but women will be randomised to open-label treatment (Canestan (Registerd Trademark)), or no treatment and the screening result is not revealed (consistent with current clinical practice).

Brief summary
Being born too early is a leading cause of perinatal death and morbidity. This trial seeks to determine whether screening for and treating asymptomatic candidiasis in pregnancy reduces the risk of this serious health problem. The trial will discover whether a simple treatment in pregnancy can reduce preterm birth. If positive, the results will be relevant to the management of every pregnancy.

No/undecided IPD sharing reason/comment
The investigators acknowledge, and concur with, the research community’s wish to publicly share trial data. Outcome data for this trial are obtained from routinely collected data that are maintained and administered by the Ministry of Health, with access predicated by the Ministry rules and regulations. To protect patient privacy, the ethics approval and data release requirements for this trial prohibit the trial researchers reporting or sharing individual patient data with other researchers, only summary data can be published or shared. Summary (aggregated) data can be provided to other researchers, as long as such data cannot result in identification of any individual patient. Any group wishing to access anonymised individual patient record data for research purposes must seek approval from the relevant Human Research Ethics Committees and, subject to ethical approval, the NSW Ministry of Health (for data release).
