Study Description

Brief Summary: Primary Objective: * To determine the clinical sensitivity and specificity of the Biomoda CyPath™ Early Lung Cancer Detection Assay using sputum specimens from two cohorts of participants and estimate the required sample size to finalize a protocol for a pivotal study. Secondary Objectives: * To assess the capability of the Biomoda CyPath™ Early Lung Cancer Detection Assay in a clinical setting to identify cancer cells, as assessed by TCPP labeled cancer cells demonstrating red fluorescence under a microscope with ultraviolet (UV) light being observed with a FITC (Fluorescein isothiocyanate) Filter. * To assess the capability of the Biomoda CyPath™ Early Lung Cancer Detection Assay to detect pre-invasive cancer in comparison with PAP sputum cytology and routine CT scan.

Detailed Description: Meso Tetra (4-Carboxyphenyl) Porphine (TCPP) is a porphyrin that can label cancer cells by reacting to the increased number of low-density lipoproteins coating the surface of cancer cells and the porous nature of the cancer cell membrane, causing the cell to fluoresce under specific wavelengths of light. The primary objective of this clinical trial was to determine the clinical sensitivity and specificity of the CyPath® Lung Cancer Detection Assay ("CyPath® Assay") using sputum specimens from two cohorts of Participants. The Study design included a protocol to assess the capability of the Biomoda CyPath® Lung Cancer Detection Assay to detect cancer in comparison with routine high-resolution, low-dose Computed Tomography (LDCT) scans. Optimization of the Assay can lead to improved sensitivity and specificity. Increase in sample size and evaluation of the entire sputum sample can increase data collection and differentiation between cohorts. Technicians in the current Study examined 12 slides containing approximately 600,000 cells. The average sputum sample pellet translates to a potential of approximately 3.5 million cells for evaluation. Evaluating the full sputum sample with the CyPath® Assay can be accomplished through flow cytometry and would increase the capture and analysis of exfoliated cancer cells in the sample. In-house studies evaluated samples from five different cancer cell lines using flow cytometry. Preliminary results showed that cancer cell lines were detected with significant fluorescence apart from normal cell fluorescence. Refinements for using the flow cytometer include optimizing the liquid-based assay and sample analysis and focus on concentration, incubation time and optimal sample volume.
