The primary objective of this study is to compare Assay results to diagnoses determined by currently accepted standards for lung cancer detection. This will be accomplished by analysis of sputum samples from three cohorts including healthy Participants, high risk Participants, and cancer patient Participants using the Assay as developed in accordance with findings of bioAffinity protocol BA-001 to confirm assay results. Adjustments will be made as necessary to finalize Assay design for clinical trials and commercialization.

The secondary objective of this study is to determine optimum methods for collection of sputum samples. Three sputum collection methods used by high risk Participants will be compared. Individuals at high risk for lung cancer will be assigned to one of three sputum collection cohorts including (1) acapella® airway assist device under medical supervision to obtain a single sputum sample; (2) acapella® airway assist device to obtain a sputum sample over a three-day period, and (3) individuals who under medical supervision will collect a single sputum sample assisted by nebulization of between 0.9% to 10% hypertonic saline. Samples will be compared to determine the optimal collection method for sample analysis by CyPath® Lung.

This study will be performed at multiple study centers to collect sputum samples from three cohorts including (1) healthy Participants, (2) individuals at high risk for lung cancer and (3) individuals who have been diagnosed with lung cancer. Participants in the high risk cohort will undergo low dose computed tomography (LDCT) scans to confirm they do not have lung cancer. LDCT scans will be evaluated by a radiologist at each site. Each subject's sputum specimen will be processed in accordance with individual experimental protocol at the laboratory of bioAffinity Technologies, Inc. (BA) located at the University of Texas at San Antonio 1604 main campus in San Antonio, Texas, or at the Research DX laboratory in Irvine, California.

Once a sample is obtained and delivered to the laboratory, the Assay methodology consists of chemical dissociation of sputum to produce a single cell suspension sample that is labeled with antibodies to identify various types of cell populations in the sample. Thereafter, sputum samples are stained with the cancer detection compound, CyPath® Lung. This compound has a unique fluorescent spectrum that can be analyzed by a flow cytometer. The flow cytometric analysis confirms that the sample is from the deep lung and identifies various cell populations based on characteristics such as cell size, granularity, and antigen expression. Cancer samples can be distinguished from non-cancer samples by the presence of highly fluorescent cells labeled by CyPath®. In this manner, CyPath® can identify lung cancer cells and other distinguishing cells that have been sloughed off in the lungs and coughed up in the sputum sample, including cancer cells.

Researchers who will be blinded as to the Participant's identity will perform the experiments that compare the characteristics of samples collected by the alternate sample collection methods and labeled by CyPath® Lung. In the latter phase of the study, the analytical results of sputum sample analysis requires that the researchers be blinded to the classification of the sputum sample and methods of collection.

Findings from the CyPath® Lung Assay will not be used in the diagnosis of Participants or subsequent treatment decisions.

The primary objective of this study is optimization of the assay to discriminate between cancer cells and non-cancer cells in sputum samples by the performance of experiments that will determine methods to liquefy sputum, select proper fixatives and buffers, determine the efficacy of use of methyl-beta-cyclodextrin (MBCD) in sputum processing and determine the use of flow cytometry for high-throughput, and in the establishment of cell count and sputum cell populations in patient samples.

The secondary objective of this study is comparison of the characteristics of sputum from three cohorts labeled with CyPath Lung to determine differential characteristics between samples taken from Participants who are not at high risk for lung cancer, Participants at high risk for lung cancer who are free of the disease and Participants with confirmed lung cancer.

A clinical study was completed to determine the clinical sensitivity and specificity of the CyPath® Early Lung Cancer Detection Assay (the "Assay") by comparing sputum specimens from three cohorts of Participants including healthy individuals, individuals at high risk for lung cancer and individuals diagnosed with lung cancer. Results were published in the Journal of Thoracic Oncology- see reference. Research now is planned to optimize the Assay as described below. Therefore, collection and analysis of sputum samples from three cohorts including healthy Participants, high risk Participants and cancer patient Participants are needed to conduct continuing research leading to optimization of the Assay.

This study will be performed at multiple study centers to collect sputum samples from three cohorts including healthy Participants who have no known lung disease, individuals at high risk for lung cancer and individuals at high risk for lung cancer who have been diagnosed with lung cancer. The sputum samples will be collected at the study site or at the Participant's home after explanation of the collection procedure by study staff. Samples will be identified with an identification number blinding the sample identity. However, the cohort classification of the sputum sample will be known by the Researcher as required to conduct the experiments. In the latter phase of the study that requires comparison of results between cohorts, researchers will be blinded to the classification of the sputum sample. Each subject's sputum specimen will be processed in accordance with individual experimental protocol at the laboratory of bioAffinity Technologies, Inc. (BA) located at the University of Texas at San Antonio 1604 main campus in San Antonio, Texas. The BA laboratory will process each sputum sample for use in optimizing the Assay. bioAffinity researchers who will be blinded as to the Participant's identity will perform the experiments that will determine methods to liquefy sputum, select proper fixatives and buffers, determine the efficacy of use of methyl-beta-cyclodextrin (MBCD) in sputum processing and determine the cell count in sputum, as described below. In the latter phase of the study, the analytical results of sputum sample analysis requires that the researchers will be blinded to the classification of the sputum sample. To ensure sample adequacy as it relates to its collection for the deep lung, samples will be analyzed by a cytologist who will perform PAP staining for the presence of macrophages. Macrophages are an indication that the sputum sample is from deep within the lungs. Findings of the experiments and comparative study will not be used in the diagnosis or treatment of Participants.

Later optimization efforts including the comparative study will require that participants in the high-risk cohort undergo low dose computed tomography (LDCT) scans to confirm they do not have lung cancer. LDCT scans will be evaluated by a licensed, independent radiologist who may advise the participant to seek additional medical advice if warranted by LDCT imaging. Participants in the cancer cohort will have undergone LDCT scans identifying them as likely to have lung cancer prior to sample collection. Findings from the CyPath® Early Lung Cancer Detection Assay will not be used in the diagnosis of Participants or subsequent treatment decisions.

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.

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.

Various measurements were taken to report the validity of the findings. Sensitivity in this study was defined as the percentage of tumor cells that were positively identified. Specificity was the percentage of true positive signals and accuracy calculated as the percentage of those patients identified as having cancer.

Testing for the study was performed at multiple locations to assess the efficacy of the CyPath Assay to detect lung cancer cells exfoliated from lung tumors present in deep-lung sputum. Participants who satisfied the inclusion/exclusion criteria were enrolled in the study and assigned to one of two cohorts (smoker with clear Low dose CT scan or "high-risk" normals," and lung cancer confirmed by pathology or "cancer").
