Brief Summary

Diagnostic trial comparing the diagnostic accuracy of the DAYE Diagnostic Tampon (DDT) with a vaginal swab (self-collected and clinician taken).

Detailed Description

MAIN STUDY DESIGN

A diagnostic trial comparing the diagnostic accuracy, usability and acceptability of the DAYE Diagnostic Tampon (DDT) compared to standard vaginal self-swabs and clinician administration of a vaginal swabs. Diagnostic accuracy will be compared for detection of Chlamydia, Gonorrhoea, BV & HPV.

A total of 350 eligible participants will be enrolled into the trial in the UK and Italy. To adequately assess DDT performance on specificity and sensitivity, participants will be recruited from one of two groups:

• Group 1: 50 participants with a recent confirmed HPV diagnosis (UK and Italy)
• Group 2: 300 participants from the general population (UK only)

All participants will be randomised according to sample order for the DDT and self-swab using block randomisation:

• Group A: Approximately half the participants will perform the self-swab followed by the DDT.
• Group B: Approximately half the participants will perform the DDT followed by the self-swab

All eligible participants will be provided with a trial kit containing the DDT and self-swab and attend at least 1 clinic visit as part of their participation in the trial. Participants will also provide answers to questionnaires at baseline and after all sampling is complete.

Participation in the trial is expected to last approximately 2-3 weeks (dependent on timing of clinic appointment(s)). All samples collected during the trial will be sent to a central laboratory for analysis, either in the UK or Italy i.e., samples will be analysed in the country they were collected.

SUB-STUDY DESIGN

A maximum of 210 eligible participants will be recruited and provide 2 samples to a decentralised sub-study to assess the DDTs performance compared to a self-taken vaginal swab. Recruitment will be stopped as soon as 21 positive cases of STI are confirmed by the lab.

• Group 3: 210 participants with suspected or recently confirmed chlamydia or gonorrhoea.

All participants will be randomised according to sample order for the DDT and self-swab using block randomisation:

• Group A: Approximately half the participants will perform the self-swab followed by the DDT.
• Group B: Approximately half the participants will perform the DDT followed by the self- swab

Pre-screening, informed consent, screening and eligibility assessments will occur online. Trial team will confirm e-consent and eligibility. Randomisation will be performed at the point of enrolment by a member of the trial team using a re-generated list of treatment allocation blocks. Some demographic information and medical history will be collected at baseline. All eligible participants will be provided with a trial kit containing the DDT and self-swab which they will use at home and send directly to the testing laboratory. Participants will also provide answers to questionnaires at baseline and after all sampling is complete. Participants will enter data directly into the EDC platform. Participation in the sub-study is expected to last approximately 1 week. All samples collected during the trial will be sent to a central accredited laboratory(s) for analysis in the UK.

Study Groups

Arm A: Self-swab then DDT

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.

Group Type: OTHER

DAYE Diagnostic Tampon

Intervention Type: DEVICE

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-swab

Intervention Type: DIAGNOSTIC_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 swab

Intervention Type: DIAGNOSTIC_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.

Arm B: DDT then self-swab

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