Outcome Measures

Primary Outcomes (1)

  • Evaluate the diagnostic accuracy of the Daye Diagnostic Tampon for detecting Chlamydia, Gonorrhea, BV and HPV

    Accuracy of the STI, BV and HPV detection using menstrual tampons compared to other specimen collection methods (clinician taken and self-swab) via assays

    Within 4 weeks of the samples being received at the lab.

Secondary Outcomes (9)

  • Assess the usability of the DDT (via After-Scenario Questionnaire - ASQ)

    Post-sampling (once all samples are collected) - at study completion usually after 4 weeks

  • Explore participants views of the usability and acceptability of the DDT

    Pre-sampling (baseline) and Post-sampling (once all samples are collected) - at study completion usually after 4 weeks

  • Explore participants views of the usability and acceptability of the DDT

    Through study completion, an average of 4-6 weeks

  • Assess whether the DDT is a preferred sampling method for participants

    Pre-sampling (baseline) and Post-sampling (once all samples are collected) - at study completion usually after 4 weeks

  • Assess if the order of sample collection (self-swab vs DDT) impacts diagnostic accuracy as assessed by assays

    Post sample analysis - 4 weeks after the last samples are received at the lab

  • +4 more secondary outcomes

Other Outcomes (2)

  • Explore the relationship between duration of wear and diagnostic accuracy.

    Post sample analysis - 4 weeks after the last samples are received at the lab

  • Sub-study Objective: Evaluate the diagnostic accuracy of the Daye Diagnostic Tampon for detecting STIs (Chlamydia, Gonorrhoea) specifically demonstrating a sensitivity of more than 70% for DDT.

    Samples will be analysed around 2 weeks after collection. The outcome will be assessed as soon as 21 positive samples have been obtained.

Study Arms (4)

Arm A: Self-swab then DDT

OTHER

Participants will take the self-swab sample, followed by the DDT sample at home. They will then have the clinician swab taken in the clinic.

Interventions

The DAYE Diagnostic Tampon is a class A in vitro diagnostic device. It has CE certification (self-certified via a declaration of conformity, following the IVDR (EU) 2017/746). The DDT is constructed entirely from woven cotton and consists of an absorbent core wrapped in a protective sleeve. The DDT is loaded in an applicator to aid with insertion.

Vaginal self-swabDIAGNOSTIC_TEST

A vaginal self-swab typically consists of a long, slender, and flexible stick or handle, often made of plastic or a similar material. At one end, there's a soft, absorbent tip made of cotton or synthetic material. This tip is designed to collect a sample from the vaginal walls or cervix.

Clinician vaginal swabDIAGNOSTIC_TEST

A clinician vaginal swab is a medical tool used by healthcare professionals to collect samples from the vaginal canal for diagnostic purposes. It's typically a long, thin, and flexible instrument. At one end, there's a cotton, rayon, or synthetic tip designed to collect cells, discharge, or other materials from the vaginal walls, cervix, or other areas within the vaginal canal. The clinician swab is not taken in sub-study participants.

Eligibility Criteria

Age25 Years - 65 Years
Sexfemale
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Individuals aged 25-65 years.
  • People assigned female at birth (AFAB).
  • Sexually active individuals. In this case, "sexually active" is defined as having penetrative vaginal sex.
  • Group 1 only: Confirmed HPV+ diagnosis within the past 4 weeks.
  • a. UK only: Ability to upload evidence of this diagnosis to the trial ePRO system (e.g. via a screenshot of the NHS app, or similar to be reviewed by the trial team).
  • Willingness to give informed consent and adhere to trial procedures.

You may not qualify if:

  • Previous hysterectomy or total hysterectomy with removal of cervix
  • Known allergy or sensitivity to tampons
  • History of TSS (both tampon-associated and non-tampon associated)
  • Individuals who are pregnant or breastfeeding.
  • Participation in another interventional clinical trial or use of investigational drugs in the last 30 days.
  • Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial. -

Model Details: MAIN STUDY: All participants will have 3 samples taken: DAYE Diagnostic Tampon (DDT), self-swab and clinician administered swab. Participants will be randomised into 2 groups for sampling order between the DDT and self-swab. SUB-STUDY In the sub-study will only perform the DDT and self-swab. Participants will be randomised according to sample order for the DDT and self-swab.
