Clinical Evaluation of the OncAlert RAPID in Subjects Presenting for Evaluation and/or Initial Biopsy; Impact on Decision-Making

Overview

The OncAlert Oral Cancer RAPID Test (OncAlert RAPID) is a qualitative point-of-care lateral flow assay to aid in the decision to biopsy in patients with clinical features associated with oral potentially malignant disorders and or oral/oropharyngeal cancer (i.e. head and neck squamous cell carcinoma).

Proposed Intended Use Statement

The device measures soluble CD44 and total protein in saliva samples collected in saline. The test is an adjunct to the biopsy decision process, and not intended as a screening or stand-alone diagnostic assay. To be used in adults 23 years and older. Not intended for use in pregnant women.

STUDY OBJECTIVES

The principal objectives of this study are to:

• Validate the OncAlert RAPID Test, with an NPV ≥ (1-prevalence),
• Evaluate OncAlert RAPID Test results in patients without immediate biopsy, both at baseline and scheduled follow-up visit (approximately 1-3 months), to assess impact on outcome,
• Evaluate the independent and associated contribution of readily available clinical variables including age, race, gender, HPV status, socioeconomic level, tobacco, and alcohol use with the biopsy and test results.

STUDY OVERVIEW

Study Approach

Prospectively collect 5cc of normal saline after a combination of swish, gargle and spit into the provided collection specimen cup. 1cc will be removed and sequestered for subsequent downstream analyses (Section 7). Specimens will be collected at baseline (time of biopsy) as per standard practice at each site. The OncAlert RAPID Test cassette is inserted into the specimen cup and read directly from the cassette in 10 minutes. In addition, acquire comprehensive clinical - pathology and patient demographic features including age, gender, race, ethnicity, and all pathology biopsy results. Also, obtain any pertinent additional clinical data including HPV status, socioeconomic status, smoking, drinking history, and pertinent features related to oral health. It is presumed that some patients within the current biopsy protocol will undergo treatment as a result of the biopsy diagnosis. The clinical-pathology data, when accessible, for these patients will be collected for subsequent secondary analyses. A central pathology review for all biopsy results will be performed and incorporated into the final analyses.

Study Duration

For Cohorts 1a and 1b patients, the pathology results of clinically directed incisional / diagnostic biopsy will be followed until finalized and received.

Cohort 2 patients not having an initial incisional / diagnostic biopsy at the initial visit will have an additional OncAlert® RAPID test performed within 1 -3 months±14 days (or as defined by standard of care (SOC)after the initial visit.)

The study will conclude after all data is collected and analyzed. This could vary from 12 to 36 months or more depending on accrual rates at the open sites and other factors.
