Cervical Carcinoma, Human Papillomavirus Infection
Conditions
Brief summary
This clinical trial evaluates the use of self-collected vaginal samples for human papillomavirus (HPV) testing in patients referred for a colposcopy and/or cervical excisional procedures to improve cervical cancer prevention. HPV is a common virus which usually causes infections that last only a few months, but sometimes can last longer. It is known to cause a variety of cancers including cancer of the cervix. Even though there are ways to detect cervical cancer early, many individuals do not undergo screening that involves pelvic exams. Over half of all new cervical cancer cases are among those who have either never been screened or who are not screened enough. Without appropriate screening and care, preventable pre-cancers may turn into cancer. A new way to detect cervical cancer is to have individuals collect their own vaginal sample for HPV testing to know their risk for cervical cancer. This may give individuals more flexibility and comfort having the ability to collect samples themselves, compared to a doctor performing a speculum examination and collecting the samples in a clinic. This study compares clinical accuracy of HPV testing on self-collected vaginal samples versus cervical samples collected by clinician. The Self-collection for HPV Testing to Improve Cervical Cancer Prevention (SHIP) Trial is part of the National Cancer Institute (NCI)'s Cervical Cancer 'Last Mile' Initiative, a public private partnership that seeks to increase access to cervical cancer screening. The SHIP Trial focuses on developing clinical evidence to inform the US Food and Drug Administration (FDA)'s regulatory reviews of self-collection approaches as alternative sample collection approaches for cervical cancer screening. Several industry partner-specific self-collection device and assay combinations will be non-competitively and independently evaluated with a similar study design framework to inform pre-approval and/or post-approval regulatory requirements.
Detailed description
PRIMARY OBJECTIVES: I. To evaluate clinical accuracy (including clinical sensitivity, clinical specificity, false positive rate, and false negative rate) for the detection of cervical precancer/cancer and agreement/concordance (including positive percent agreement and negative percent agreement) on self-collected (SC) versus clinician collected (CC) samples for the following HPV genotype detections and groupings by Becton, Dickinson and Company (BD) Onclarity (trademark) HPV assay: Any high risk (HR) HPV genotype, HPV16, HPV18, HPV31, HPV45, HPV51, HPV52, HPV33/58, HPV35/39/68, HPV56/59/66, HPV16 and/or HPV18, other 12 HR-HPV types (grouped). (Group A) II. To conduct an observational study among women attending regular cervical cancer screening ("intended use population" for the at-home collection indication). (Group B) EXPLORATORY OBJECTIVES: I. To evaluate human factors affecting usability, acceptability, and preferences for self-collection. (Group A) II. To evaluate agreement/concordance (including positive percent agreement and negative percent agreement) on SC versus CC samples for the following HPV genotype detections and groupings by BD Onclarity™ HPV assay: Any HR HPV genotype, HPV16, HPV18, HPV31, HPV45, HPV51, HPV52, HPV33/58, HPV35/39/68, HPV56/59/66, HPV16 and/or HPV18, other 12 HR-HPV types (grouped). (Group B) III. To evaluate human factors affecting usability, acceptability, and preferences for self-collection. (Group B) OUTLINE: Patients are assigned to 1 of 2 groups. GROUP A: Patients undergo self-collection of two vaginal samples and then undergo clinician-collection of a cervical test sample. Patients then undergo standard of care colposcopy with biopsy/endocervical curettage and/or cervical excisional procedures as clinically indicated. GROUP B: Patients undergo self-collection of two vaginal samples and then undergo clinician-collection of 1 or 2 cervical test samples. Patients may undergo standard of care colposcopy with biopsy/endocervical curettage and/or cervical excisional procedures as clinically indicated. After completion of study intervention (one time), laboratory results available within 30 days are collected for study analysis purposes.
