Detailed Description
PRIMARY OBJECTIVE:
I. To evaluate the sensitivity and specificity of a diagnostic strategy combining esophageal sponge sampling with the 'EsophaCap' sponge device with use of the EsoCAN assay, a novel molecular biomarker assay, among patients with histologically-confirmed ESCC cases and controls.
SECONDARY OBJECTIVES:
I. To evaluate the sensitivity and specificity of a diagnostic strategy combining esophageal sponge sampling with the 'EsophaCap' sponge device with use of the the EsoCAN assay, among patients with histologically-confirmed ESD and controls.
II. To evaluate the safety and feasibility of 'EsophaCap' a swallowable and retrievable sponge, as a non-invasive strategy for screening and early detection of ESCC and its precursor, ESD, in Tanzania.
EXPLORATORY OBJECTIVES:
I. Sensitivity and specificity of esophageal sponge sampling with standard cytological examination among histologically-confirmed ESCC cases and controls.
II. Sensitivity and specificity of esophageal sponge sampling with standard cytological examination among histologically-confirmed ESD cases and controls.
III. To examine methylation levels in new and previously identified genes among patients recruited as suspected ESCC cases who are found to have an alternative diagnosis, with the goal of optimizing the EsoCAN Assay.
OUTLINE:
Each participant will undergo esophageal sponge sampling suing the 'EsophaCap' sponge device. Participants will be on study for up to 38 days.

Intervention / Treatment |
---|---|
Experimental: Esophageal Squamous Cell Carcinoma (ESCC) Cases
Each study participant will undergo esophageal sponge sampling using the 'EsophaCap' sponge device.
Group 1 will include a safety-phase, which will consist of a lead-in cohort of 8 patients with ESCC.
Subsequent recruitment of ESCC Cases (Group 1) will not commence until the Data Safety Monitoring Board (DSMB) has deemed the safety lead-in data appropriate for continuation.
Following collection of esophageal cells, samples will be assessed using the EsoCAN assay.
Study participant evaluations will be taken at baseline, immediately after undergoing esophageal sponge sampling, and 7 days following administration of the 'EsophaCap' device.
