Brief summary
The EQUIP Study is testing whether high-risk human papillomavirus (hrHPV), the virus that causes most cervical cancers, can be accurately detected from menstrual blood collected at home. People who have been referred for colposcopy after an abnormal Pap or hrHPV test will use the Q-Pad Kit during their period to collect menstrual samples on a special menstrual pad and mail them to a central laboratory for hrHPV testing. The same participants will have a standard cervical sample collected for routine hrHPV testing and will undergo colposcopy as part of their usual care. By comparing hrHPV results from menstrual samples with results from cervical samples and biopsy findings, the study will evaluate how well the Q-Pad hrHPV Test System detects cervical precancer and will also assess how easy and acceptable it is for participants to use this at-home collection method.
Detailed description
The EQUIP Study is a prospective, multicenter method-comparison study designed to evaluate the diagnostic performance of the Q-Pad hrHPV Test System for cervical cancer screening. Menstruating adults referred for colposcopy after an abnormal cervical screening result receive a mailed Q-Pad Kit and use it during the menstrual cycle immediately after their clinic visit to collect a menstrual samples at home, guided by written instructions and an optional accompanying smartphone application. These samples are returned by mail to a central laboratory, where hrHPV testing is performed using a PCR assay. At the colposcopy visit, clinicians obtain a standard cervical specimen for routine cytology and hrHPV testing on the same assay platform and perform colposcopy with biopsy as clinically indicated. Each participant therefore provides both an at-home menstrual sample (index test) and a clinician-collected cervical sample (comparator) within the same episode of care, with biopsy and histopathology providing disease status. The study focuses on comparing hrHPV results between the two specimen types and on evaluating safety, specimen adequacy, and participant usability and acceptability of the Q-Pad at-home menstrual collection approach.
Interventions
Participants will receive a mailed Q-Pad Kit, which includes two Q-Pads (menstrual pads with removable collection strips called Q-Strips), a Q-Strip Container with desiccant for storing and shipping the strips, and a prepaid return mailer. During the menstrual cycle after their colposcopy visit, participants will follow the Instructions for Use to passively collect menstrual blood with the Q-Pads, then remove the Q-Strips and place them in the Q-Strip Container for mailing to the central laboratory for hrHPV testing. At the colposcopy visit, the clinician will also collect a cervical sample in ThinPrep liquid-based cytology medium for hrHPV testing, which will serve as the comparator specimen.

Eligibility
Inclusion criteria
* You are 25 years old or older and have an intact cervix. * You were referred for a colposcopy after an abnormal Pap or HPV screen. * Your periods come regularly-about every 21-35 days. * You own a smartphone, have an email address, and can read the Qvin app instructions in English. * You are willing to sign the consent form (electronically). * You agree to use a condom for any vaginal intercourse or shared penetrative toy use from Q-Pad collection until the colposcopy visit if engaging with a new sexual partner during this period.
Exclusion criteria
* You are pregnant or think you might be. * You are unwilling or unable to use the two Q-Pads and mail them back (mailing costs are covered). * You had treatment for cervical pre-cancer (CIN2+)-such as LEEP, cone, or ablation-within the last 12 months. * You have already joined this study or are in another cervical-screening / HPV study right now.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical Performance vs Histology | Through study completion, an average of 1 year. | Clinical sensitivity defined as the proportion of participants with biopsy-confirmed CIN2+ whose menstrual-blood hrHPV result (Q-Pad hrHPV Test System) is positive and Clinical specificity defined as the proportion of participants with \<CIN2 on histology whose menstrual-blood hrHPV result is negative. |
| Proportion of participants with at least one reportable device-related adverse event (ADE or SADE) | Through study completion, an average of 1 year. | Proportion of participants who experience at least one adverse event or device deficiency that is not on the protocol's non-reportable event list. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Positive, negative, and overall percent agreement between Q-Pad hrHPV testing and clinician-collected cervical hrHPV testing | Through study completion, an average of 1 year. | Positive percent agreement (PPA), negative percent agreement (NPA), and overall percent agreement (concordance) between the Q-Pad hrHPV Test System result on menstrual blood (index test) and the hrHPV result from the paired clinician-collected cervical ThinPrep specimen (comparator test). |
| Q-Pad hrHPV Test System validity rate and participant usability/acceptability | Through study completion, an average of 1 year. | Proportion of returned Q-Pad menstrual collections that yield a valid hrHPV test result in the central laboratory (i.e., not invalid or quantity-not-sufficient \[QNS\]), together with participant usability and acceptability scores for the Q-Pad kit. |
