PART
I
Item
1. Business
Business
Overview
bioAffinity
Technologies, Inc. (the “Company,” “bioAffinity,” “we,” or “our”) develops noninvasive
diagnostics to detect early-stage lung cancer and other diseases of the lung. We are advancing research into our therapeutic discoveries
which could result in broad-spectrum cancer treatments in the future. We develop proprietary noninvasive diagnostic tests using flow
cytometry and automated analysis developed by artificial intelligence (“AI”). Our diagnostic tests analyze cell populations,
including cancer and cancer-related cells, that are indicative of a specific diseased state.
We
were formed as a Delaware corporation on March 26, 2014. On June 15, 2016, we formed OncoSelect® Therapeutics, LLC (“OncoSelect®”),
a Delaware limited liability company and our wholly owned subsidiary which is a preclinical-stage biopharmaceutical discovery company
with a focus on therapeutics that deliver cytotoxic (cell-killing) effects on a broad selection of human cancers from diverse tissues
while having little or no effect on normal cells. On August 14, 2023, we formed Precision Pathology Laboratory Services, LLC (“PPLS”),
a Texas limited liability company and our wholly owned subsidiary. Research and optimization of our platform technologies for in vitro
diagnostics and technologies are conducted in laboratories at The University of Texas at San Antonio and PPLS in San Antonio, Texas.
Our
first diagnostic test, CyPath® Lung, addresses the need for noninvasive detection of early-stage lung cancer. Lung cancer
is the leading cause of cancer-related deaths worldwide. Physicians order CyPath® Lung to assist in their assessment of
patients who are at high risk for lung cancer. The CyPath® Lung test enables physicians to more confidently identify patients
who will likely benefit from timely intervention and more invasive follow-up procedures and those who are likely without lung cancer
and should continue routine screening. CyPath® Lung has the potential to increase overall diagnostic accuracy of lung
cancer, which could lead to increased survival, fewer unnecessary invasive procedures, reduced patient anxiety, and lower medical costs.
CyPath®
Lung uses flow cytometry technology to detect and analyze cell populations in a person’s sputum, or phlegm, to find characteristics
indicative of lung cancer, including cancer and/or cancer-related cells that have shed from a lung tumor. The flow cytometer is a well-established
instrument used in many commercial laboratories. Flow cytometry collects data pertaining to properties of single cells labeled with antibodies
and dyes specific to cell types and characteristics. Sputum is an excellent sample for analysis because it is in direct contact with
any malignancy in the lungs and can provide information about its area of field cancerization and the lung microenvironment. CyPath®
Lung uses automated data analysis developed by AI that allows an entire sample of sputum averaging 16 million cells to be examined
in approximately 30 minutes, allowing for cost-effective, large-scale commercialization.
We
conducted a 150-patient test validation trial of people at high risk for lung cancer including patients with the disease (N=28) and those
who were cancer-free (N=122) that resulted in CyPath® Lung’s overall 88% specificity, meaning the ability to correctly
identify a person without cancer, and 82% sensitivity, meaning the ability to correctly identify cancer in a person with the disease.
For the subset of patients in this trial who had lung nodules 20 millimeters (“mm”) or smaller, this trial resulted in 92%
sensitivity, 87% specificity, 99% negative predictive value, and 88% accuracy. In this subset of 132 individuals with small nodules,
119 patients were cancer-free and 13 had confirmed lung cancer. The detection of small lung nodules in people who have early-stage cancer
can increase lung cancer survival.
Through
OncoSelect®, our research has led to discoveries of novel potential cancer therapeutics that specifically and selectively
target cancer cells that have been grown in petri dishes.
In
September 2023, through our wholly owned subsidiary PPLS, we acquired the assets of Village Oaks Pathology Services, P.A.,(“Village
Oaks”) a Texas professional association d/b/a Precision Pathology Services, including a clinical anatomic and clinical pathology
laboratory and related services business in San Antonio, Texas. The laboratory is accredited by the College of American Pathologists
(“CAP”) and certified under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”).

Registered
Direct Offering
On
March 6, 2024, we raised $2.5 million in gross proceeds from the sale to four institutional investors of (1) 1,600,000 shares of our
common stock (the “Shares”), par value $0.007 per share (“Common Stock”) in a registered direct offering, and
(2) warrants to purchase an aggregate of 1,600,000 shares of Common Stock (the “Common Warrants”) with an exercise price
of $1.64 in a concurrent private placement. See “Management’s Discussion and Analysis of Financial Condition and Results
of Operations” for a more detailed discussion of this transaction.
CPT
Code Specific to CyPath® Lung for Proprietary Laboratory Analyses
On
November 30, 2023, we announced that the Centers for Medicare and Medicaid Services (“CMS”) had made a final determination
for payment for CyPath® Lung, our noninvasive test for early-stage lung cancer, for the 2024 calendar year. Effective
January 1, 2024, CyPath® Lung is on CMS’ 2024 clinical laboratory fee schedule. The CPT Proprietary Laboratory Analyses
(“PLA”) code assigned to CyPath® Lung is 0406U with the descriptor “Oncology (lung), flow cytometry,
sputum, 5 markers (meso-tetra [4- carboxyphenyl] porphyrin [TCPP], CD206, CD66b, CD3, CD19), algorithm reported as likelihood of lung
cancer.”
CyPath®
Lung Branding
In
2023, we developed a series of marketing tools based on branding for CyPath® Lung that emphasize our test’s
ability to assist physicians with next steps in patient care. In January 2024, we began using the new marketing materials with both physicians
and patients. The branding concepts were developed by the marketing and advertising firms of Havas Health & You, Trinity Life Sciences,
and K2MD to build the CyPath® Lung brand and position it for success in the cancer diagnostics sector.
PPLS
Passes CAP Inspection
On
January 11, 2024, PPLS successfully passed its bi-annual CAP inspection necessary for continuing operations. CAP accreditation ensures
that laboratories meet the highest standards of quality and patient care under the Clinical Laboratory Improvement Amendments (CLIA),
including personnel qualifications, equipment, facilities, safety protocols, and overall management and quality of testing.
Jamie
Platt, Ph.D., Joins Board of Directors
In
December 2023, Jamie Platt, Ph.D., Managing Director and Chief Executive Officer of Pictor Limited, where she is leading a turnaround
by restructuring and accelerating product development, joined the bioAffinity Technologies Board of Directors. Dr. Platt has more than
two decades of experience bringing novel diagnostic technologies to global markets. She was instrumental in merger and acquisition exits
for two diagnostic companies with a combined value of approximately $1 billion. She previously was Chief Operating Officer of Personal
Genome Diagnostics which was acquired by LabCorp for $575 million. We believe Dr. Platt’s scientific acumen, business leadership,
and board experience will contribute to the Company’s growth and successful commercialization of CyPath® Lung.
Sandeep
Bansal, M.D., Joins Medical and Science Advisory Board
In
February 2024, Sandeep Bansal, M.D., Medical Director of Pennsylvania’s Lung Innovations Network, joined our Medical and Scientific
Advisory Board. Dr. Bansal is Board certified in pulmonary disease, critical care medicine and interventional pulmonology and has also
served as principal investigator of multiple clinical research trials and peer reviewer for several medical journals. Lung Innovations
Network, a patient-centered practice that offers comprehensive lung care to over 10,000 patients in central and western Pennsylvania,
incorporated CyPath® Lung into its practice to aid in the detection of early-stage lung cancer in March 2024. We believe
Dr. Bansal’s experience as both clinician and researcher is an important asset for bioAffinity Technologies.
Continuation
of Department of Defense Research
In
the fourth quarter of 2023, we began selling CyPath® Lung tests to the Department of Defense (DOD) to conduct an observational
study, “Detection of Abnormal Respiratory Cell Populations in Lung Cancer Screening Patients Using the CyPath® Lung
Assay,” and for research and development on using bronchoalveolar lavage fluid as a biological sample to assess cardiopulmonary
function and exercise performance in military personnel post COVID-19 infection. An additional research study was opened by Brooke Army
Medical Center in March 2023 to collect bronchoalveolar lavage samples to advance the research and development of a lung cancer test
to be used in conjunction with bronchoscopy to improve diagnostic accuracy with combined testing.
Acquisition
of Laboratory
On
September 18, 2023, PPLS consummated the acquisition of a clinical anatomic and clinical pathology laboratory and related services business
in San Antonio, Texas, pursuant to the terms of an Asset Purchase Agreement dated September 18, 2023, that we entered into with Village
Oaks Pathology Services, P.A., a Texas professional association d/b/a Precision Pathology Services, and Roby P. Joyce, M.D. PPLS is accredited
by the College of American Pathologists (“CAP”) and certified under the Clinical Laboratory Improvement Amendments of 1988
(“CLIA”). Founded in 2007 by Dr. Joyce, the Medical Director and Laboratory Director of the clinical pathology laboratory
prior to and after the acquisition, has provided pathology services to physicians practicing in a variety of outpatient settings. Since
September 2021, Village Oaks, under the trade name Precision Pathology Services, has offered CyPath® Lung for sale as
a laboratory developed test (“LDT”) for the detection of early-stage lung cancer. In addition to CyPath® Lung,
PPLS intends to continue to offer a range of laboratory services including respiratory testing for SARS-CoV-2 and influenza, anatomical
pathology, morphological stains, histological services, DNA extractions, STI testing, and women’s and men’s health testing.
Pursuant
to the terms of the Asset Purchase Agreement, PPLS acquired the laboratory assets, which included all of the assets owned by Village
Oaks other than medical assets, including the CLIA certification and CAP accreditation, which are assets Village Oaks used in connection
with its management and operation of a clinical pathology laboratory, now owned by PPLS, and related services business and assumed certain
liabilities and obligations. Pursuant to the terms of the Asset Purchase Agreement, Village Oaks received $3,500,000 in consideration
for the assets to be purchased by PPLS, of which $1,000,000 was paid by the issuance of 564,972 shares of our restricted Common Stock
to a trust controlled by Dr. Joyce which share number was determined by dividing $1,000,000 by $1.77, the average of the trading day
closing prices for the 30 days prior to September 15, 2023, rounded to the nearest whole share.
Pursuant
to the Asset Purchase Agreement, PPLS assumed all liabilities and obligations and obtained any and all rights, title and interest of
Village Oaks in and to (1) all leases for equipment and personal property related to the laboratory assets, pursuant to an Assumption
Agreement by and between Village Oaks and PPLS; (2) certain other contracts related to the laboratory assets, including the license to
develop, manufacture, use, market, and sell CyPath® Lung pursuant to the Assumption Agreement; (3) all accounts payable
of Village Oaks as of September 18, 2023, that were incurred in the ordinary course of business consistent with past custom and practice;
and (4) the lease of the premises used in connection with operation of the CLIA-certified and CAP-accredited clinical pathology laboratory,
pursuant to an Assignment and Assumption of Lease by and between and PPLS.
In
connection with the Asset Purchase Agreement, PPLS entered into various other agreements, including a Management Services Agreement with
Village Oaks, a Succession Agreement with Village Oaks and Dr. Joyce, and a Professional Services Agreement with Village Oaks pursuant
to which PPLS will provide comprehensive management and administrative services to Village Oaks in connection with the operation of its
professional cytopathology, histopathology, and clinical and anatomic pathology interpretation medical services practice. PPLS will provide
space, equipment, administrative, management and clinical personnel, billing and collection, and related management services to Village
Oaks in exchange for a management fee of 70% of the net revenues received by Village Oaks from the provision of the medical services.
The
Succession Agreement provides that Dr. Joyce, as holder of 100% of the issued and outstanding stock of Village Oaks, and Village Oaks
are restricted from disposing of their equity interests in Village Oaks, subject to certain exceptions, without the prior written consent
of us and Village Oaks.
Pursuant
to a Professional Services Agreement, Village Oaks provides pathology interpretation services as requested on behalf of PPLS based on
the professional fees approved for the CPT code for the services provided under the Medicare Physician Fee Schedule in the locality where
the test is performed.
In
connection with the Asset Purchase Agreement, we entered into an Executive Employment Agreement with Dr. Joyce for a term of three years,
pursuant to which he serves as the Medical Director and Laboratory Director of PPLS, at a base salary of $333,333 per year. Pursuant
to the Joyce Employment Agreement, Dr. Joyce was also appointed to serve on our Board of Directors.
Our
First Diagnostic Test – CyPath® Lung
Lung
cancer remains the most commonly diagnosed cancer and the leading cause of cancer-related deaths worldwide. Globally, there were an estimated
2.21 million lung cancer cases and 1.8 million lung cancer deaths in 2020, as reported by the World Health Organization in its 2020 Cancer
Fact Sheet. According to the American Lung Association (“ALA”), screening for individuals at high risk for lung cancer has
the potential to improve lung cancer survival rates by finding disease at an earlier stage when it is more likely to be curable. A study
published in the New England Journal of Medicine titled “Survival of patients with stage I lung cancer detected on CT screening”
dated October 26, 2006, reported that the survival rate of individuals with Stage I lung cancer who underwent surgical resection within
one month after diagnosis had a ten-year survival rate of 92%, as compared to the overall five-year survival rate in the U.S. of 26.5%
as reported by the ALA. Unfortunately, most lung cancer is detected in late stages. The results of a large national clinical trial that
was reported in the New England Journal of Medicine in an article dated August 4, 2011, titled “Reduced Lung-Cancer Mortality
with Low-Dose Computed Tomographic Screening” showed that screening for lung cancer using low-dose computed tomography (“LDCT”)
resulted in a reduction of the mortality rate by 20% as compared to screening by X-ray if LDCT screening is used by patients at high
risk for lung cancer on an annual basis. Therefore, LDCT scans are recommended for screening of an estimated 14 million Americans who
are at high risk for lung cancer. If half of these high-risk individuals were screened, more than 12,000 lung cancer deaths could be
prevented, according to the ALA. However, the New England Journal of Medicine article also reported that LDCT was shown to have
a low positive predictive value of less than 4%. This means that for every 100 people who receive a positive result from LDCT screening
and are suspected of having lung cancer, only four actually have the disease. A reliable, noninvasive, and cost-effective diagnostic
test can increase diagnosis of early-stage lung cancer while lowering the number of unnecessary and invasive procedures for patients
with a false positive result from LDCT screening. (A false positive test result indicates that the patient has lung cancer when he or
she does not have the disease.)
CyPath®
Lung is a test for early-stage lung cancer that is designed to meet the need for greater diagnostic certainty. Based on our internal
analysis, its use in conjunction with LDCT is predicted to improve the positive predictive value (the probability that patients with
a positive LDCT scan truly have the disease) by a factor of five. Our analysis concludes that improving the positive predictive value
of LDCT with the use of CyPath® Lung has the potential to subject fewer patients to the stresses of misdiagnosis or unnecessary
diagnostic procedures, such as biopsies, while also reducing healthcare costs.
CyPath®
Lung uses flow cytometry technology to detect and analyze cell populations in a person’s sputum, or phlegm, to find characteristics
indicative of lung cancer, including cancer and/or cancer-related cells that have shed from a lung tumor. The flow cytometer is a well-established
instrument used in many commercial laboratories. Flow cytometry collects data pertaining to properties of single cells labeled with antibodies
and dyes specific to cell types and characteristics. Sputum is an excellent sample for analysis because it is in direct contact with
any malignancy in the lungs and can provide information about its area of field cancerization and the lung microenvironment. While studies
have shown that expert cytological analysis of sputum can detect cancerous and pre-malignant cells, the level of scrutiny required for
the analysis is not feasible in the laboratory routine, according to an October 22, 2009, article, “Premalignant and malignant
cells in sputum from lung cancer patients,” published in Cancer Cytopathology. The process of looking at microscopy slides
is an extremely laborious approach and demands years of expertise. CyPath® Lung uses flow cytometry and automated data
analysis developed by AI that allows for an entire sample of sputum averaging 16 million cells to be examined in approximately 30 minutes,
allowing for cost-effective, large-scale commercialization.
In
particular, CyPath® Lung uses a synthetic porphyrin called meso-tetra (4-carboxyphenyl) porphyrin (“TCPP”).
Porphyrins are biological pigments that, when exposed to ultraviolet light at certain wavelengths, can result in the cell fluorescing
a red or purplish color that can be detected under a microscope or by flow cytometry, according to an article titled “Laboratory
Diagnosis of Porphyria,” published in Diagnostics (Basel) on July 26, 2021. Porphyrins can be man-made, like TCPP, or they
can be naturally occurring, like heme that is responsible for the red color in red blood cells. Cancer cells are known to take up certain
porphyrins in higher amounts than non-cancer cells, and the high affinity for cancer cells displayed by TCPP makes it an excellent bio-label
for cancer, according to an article published in Progress in Clinical and Biological Research in 1984 titled “A comparative
study of 28 porphyrins and their abilities to localize in mammary mouse carcinoma: uroporphyrin I superior to hematoporphyrin derivative.”
As used in CyPath® Lung, the proportion of cells with high TCPP fluorescence intensity in a patient’s sputum sample
is a significant predictor of lung cancer. We hold multiple patents protecting our use of TCPP for the diagnosis, monitoring, and treatment
of cancer. In addition, we have multiple domestic and foreign patent applications to protect the use of flow cytometry and our AI-developed
automated analysis platform in the detection of lung cancer and other lung diseases using sputum as a sample.
We
developed an algorithm as part of a test validation trial that used machine learning to distinguish samples from high-risk patients who
had lung cancer from those who are cancer-free. Results of the trial were published January 21, 2023, in the peer-reviewed journal Respiratory
Research. Village Oaks developed CyPath® Lung for sale as an LDT in accordance with the standards of the CAP and the
regulations and guidance of the CLIA program, which is administered by CMS.
CyPath®
Lung can be put into routine lab use without requiring expert evaluation of samples or being subject to operator bias. Our approach
allows the entire sputum sample to be rapidly analyzed. The numerical analysis developed with machine learning captures complex interactions
between lung cancer, the microenvironment, and areas of field cancerization that would be difficult if not impossible for individuals
to predict or detect reliably by eye. For example, during test development, we discovered that viability staining density suggests a
link with apoptosis, or cell death, that is linked to many cancers, including lung cancer. Our model also suggests that specific markers
of immune cell populations may be informative as to the presence of cancer in the lung. These findings are the result of our machine
learning approach to automated analysis.
CyPath®
Lung uses sputum that is obtained noninvasively by patients in the privacy of their home. Physicians most often order the test
for patients after CT imaging reveals one or more pulmonary nodules that are suspected to be lung cancer. A patient collects his or her
sample using a hand-held, noninvasive assist device, ICU Medical’s Acapella® Choice Blue, that acts to break up
mucus in the lungs and help a person cough up sputum from the lung into a collection cup. The Acapella® Choice Blue has
been 510(k) cleared by the FDA as a positive expiratory pressure device to help mobilize lung secretions in people with certain lung
conditions.
The
sputum sample is shipped overnight by the patient to PPLS and processed into a single-cell suspension, then labeled with antibodies that
distinguish different cell types and the synthetic porphyrin TCPP that identifies cancer cells and/or cancer-associated cells. Our test
can analyze an average sputum sample containing about 16 million cells in approximately 30 minutes using integrated software for high-throughput,
user-friendly standardized analysis of flow cytometric sample data. A physician’s report is generated within minutes after data
acquisition. The report stratifies the patient into one of two risk groups. Those patients deemed “likely or very likely”
to have cancer may benefit from aggressive intervention. Those “unlikely or very unlikely” to have a malignancy may continue
imaging surveillance. The physician also receives a numerical score between 0.1 to 1.0, with 0.1-0.49 being a negative result and 0.5
to 1.0 considered positive for lung cancer. The proprietary automated analysis software was developed and is wholly owned and patent
protected by bioAffinity Technologies.
Physicians
receive test results within three days after the laboratory receives the patient’s sputum sample. CyPath® Lung testing
helps identify patients who should undergo more aggressive follow-up procedures to confirm a suspected lung cancer. When CyPath®
Lung sample analysis determines a patient is unlikely or very unlikely to have lung cancer, the result can serve to support a physician’s
decision to monitor this patient by following a recommended LDCT screening routine.
As
reported in an article titled “Detection of Early-Stage Lung Cancer in Sputum using Automated Flow Cytometry and Machine Learning,”
published in Respiratory Research on January 21, 2023, we conducted a 150-patient test validation trial of people at high risk
for lung cancer including patients with the disease (N=28) and those who were cancer-free (N=122) that resulted in CyPath®
Lung’s overall 88% specificity, meaning the ability to correctly identify a person without cancer, and 82% sensitivity, meaning
the ability to correctly identify cancer in a person with the disease. For the subset of patients in this trial who had lung nodules
20 mm or smaller or no nodules at all, this trial resulted in 92% sensitivity, 87% specificity, 99% negative predictive value, and 88%
accuracy. In this subset of 132 individuals with small nodules, 119 patients were cancer-free and 13 had confirmed lung cancer. Eight
out of 10 (80%) of Stage I tumors were correctly identified. Sensitivity is the percentage of persons with the disease – in this
case, lung cancer – who are correctly identified by the test. Specificity is the percentage of persons without lung cancer who
are correctly identified by the test. The cancer group included all lung cancer types, but mostly squamous cell carcinoma and adenocarcinoma
lung cancer (in near equal numbers), showing that CyPath® Lung detects all types of lung cancer. The detection of small
lung nodules in people who have early-stage cancer can increase lung cancer survival.
In
this 19-month test validation trial participants provided a sputum sample and were released from the study after a physician either confirmed
the individual was cancer-free by examination of CT imaging or confirmed the presence of lung cancer by biopsy. Flow cytometry and patient
data used in the analysis produced results that included (1) the proportion of cells with a high ratio of high TCPP fluorescence intensity
over cell size; (2) the proportion of cells with an intermediate ratio of fluorescence intensity caused by the viability dye (FVS510)
over cell size; (3) the proportion of cells that were CD206 negative but positive for one or more of the following markers: CD66b (granulocytes),
CD3 (T cells), and CD19 (B cells); and (4) patient age.
The
CyPath® Lung technology is based on scientific work originating at Los Alamos National Laboratory in collaboration with
St. Mary’s Hospital in Colorado. In the Los Alamos research study, sputum samples from lung cancer patients were differentiated
from non-cancer samples with 100% accuracy. This early research was conducted with sputum from 12 uranium miners. Microscope slides of
sputum samples were labeled with the synthetic fluorescent porphyrin TCPP. The Los Alamos research study of 12 uranium miners included
eight men with cancer and four healthy individuals. Researchers were blinded to the sample origin and looked for the presence of highly
fluorescent cells indicating uptake of TCPP as an indicator of lung cancer. The length of the study and specific follow-up was not reported,
but researchers did report that one patient entering the study as a healthy subject was correctly diagnosed with cancer by the test.
Later, a blinded clinical trial was conducted and results published September 2015 in an article titled “Early Detection of Lung
Cancer with Meso-Tetra (4-Carboxyphenyl) Porphyrin-Labeled Sputum” in the Journal of Thoracic Oncology. This study reported
on an earlier version of CyPath® Lung that used a fluorescent microscope to directly identify cells labeled with TCPP
in one-third or less of the sputum sample. For each trial participant, researchers manually scanned 12 microscope slides labeled with
TCPP for the presence of red fluorescent cells (“RFCs”) displaying a spectral signature that indicated uptake of TCPP in
the cell. In addition to measuring the spectral signature, the fluorescent intensity and cell size of RFCs were measured. The test data,
including fluorescent intensity over cell size, was analyzed. The trial was conducted over 24 months and resulted in 81% test accuracy,
77.9% sensitivity, and 65.7% specificity in the ability to correctly differentiate between samples from lung cancer patients and those
at high risk who were cancer-free. The Patriquin trial required participants to provide a sputum sample and CT imaging of the lungs.
Those in the cancer cohort underwent a biopsy to confirm lung cancer. High-risk patients displaying indeterminate nodules were followed
for 18 months to confirm they were cancer-free. The Patriquin study concluded that optimizing the test to provide for analysis of the
entire sputum sample would improve results.
On
January 1, 2024, the Medicare reimbursement code 0406U specific for CyPath® Lung became effective after multiple regulatory
decisions in 2023 leading to approval. On June 6, 2023, the American Medical Association (“AMA”) approved a Current Procedural
Terminology (“CPT”) Proprietary Laboratory Analysis (“PLA”) code specifically for use with CyPath®
Lung, which was publicly released on June 30, 2023. The new CPT code became effective for use on October 1, 2023. On November 30, 2023,
we announced CMS’ final determination for payment for CyPath® Lung, and CyPath® Lung is on CMS’
2024 clinical laboratory fee schedule. The CPT PLA code assigned to CyPath® Lung is 0406U with the descriptor “Oncology (lung),
flow cytometry, sputum, 5 markers (meso-tetra [4- carboxyphenyl] porphyrin [TCPP], CD206, CD66b, CD3, CD19), algorithm reported as likelihood
of lung cancer.”
We
have an agreement with GO2 Partners to produce patient collection kits and to provide warehousing and distribution services for sending
out the kits. Laboratory reagents, supplies, and equipment are commercially available through multiple vendors. Sample processing, labeling,
and data collection can be accomplished by a laboratory technician skilled in general laboratory techniques. Data analysis leading to
a physician’s report is done by automated analysis software fully integrated into the test.
To
our knowledge, CyPath® Lung is the first cancer diagnostic that combines flow cytometry and automated analysis to predict
the presence of lung cancer from sputum samples.
The
Cancer Diagnostics Market and CyPath® Lung
The
global cancer diagnostic market is projected to grow from an estimated $102.24 billion in 2022 to $162.57 billion in 2030, with a compound
annual growth rate (“CAGR”) of 6.1%, according to a market research report issued by Research and Markets in June
2023. A January 2023 report, also by Research and Markets, stated that the market worldwide for lung cancer diagnostic tests was
estimated at $2.6 billion in 2022 and is projected to reach $4.7 billion by 2030, with a CAGR of 7.8% over 2022-2030. We have the potential
to play a significant role in the cancer diagnostic market because our platform is noninvasive, cost-effective, and has the potential
to lead to better patient outcomes.
Comparison
of CyPath® Lung to Current Standards of Care
Our
business model is to immediately address the need for a quick-to-market, noninvasive, cost-effective lung cancer diagnostic that will
save lives and reduce medical costs. The U.S. Preventive Services Task Force recommended new guidelines for screening in March 2021,
nearly doubling the number of Americans at high risk for lung cancer who are recommended for annual screening to 14 million people, according
to the ALA. In November 2023, the American Cancer Society updated its guidelines for lung cancer screening to include all former smokers
over the age of 50 regardless of when they quit, increasing the number of American adults eligible for screening to 19 million. China
has an estimated 300 million smokers, according to the World Health Organization. In Europe, it is estimated that there is one new case
of lung cancer diagnosed every minute, with incidence rates for males the highest in Eastern European countries and a five-year survival
rate of only 13%, as reported by a May 2021 article, “Lung cancer screening in Europe: where are we in 2021?” published in
Translational Lung Cancer Research. We expect to pursue CE marking of CyPath® Lung for sale in the European Union.
We
conducted market research in the U.S. with pulmonologists, oncologists, cardiothoracic surgeons, radiologists, and internists engaged
in the diagnosis and treatment of lung cancer to help assess their reactions to our diagnostic tool. Research revealed a strong interest
in CyPath® Lung, driven by the high level of unmet clinical need for noninvasive diagnostics. A survey conducted with
240 pulmonologists and internists, the primary audience for the test, showed that 96% would use CyPath® Lung if it were
available today as an adjunct used for diagnosis after LDCT screening. Physicians responded favorably to a noninvasive diagnostic technology
that gives them more confidence in their decision to proceed with more aggressive follow-up procedures if the test comes back positive.
If test results are negative, physicians can rule out lung cancer, thus reducing the number of costly invasive procedures that result
from the LDCT false-positive rate.
CyPath®
Lung Business Development Plan
We
believe in the viability of our business plan based on the circumstances surrounding our business that are known to us as of the date
of this Annual Report. However, the timing, strategies, and stages of our business plan may evolve in light of new circumstances that
cannot be predicted with certainty at this time. Our business plan envisions four phases of expanding market entry into the U.S., the
EU, and worldwide that are timed to maximize our resources and minimize market risk. Phase 1 of our business plan has already begun with
a limited market launch of our LDT CyPath® Lung in Texas. This limited test market launch is designed to evaluate our
marketing program and help us ensure each step in the care pathway – from the initial order by physicians to sputum collection
and processing, to generating and delivering the patient report – is efficient and effective. This limited test market approach
allows us to refine future positioning and develop strategic insight for our CyPath® Lung test before expanding to a larger
market.
We
believe that our strategy related to a limited market launch is proving successful. On March 5, 2024, we reported accelerating growth
of 375% in CyPath® Lung tests ordered and processed over from December 1, 2023, through February 29, 2024, as compared
to the prior three-month period. We attribute the growth in sales to three 2023 initiatives that came to fruition early in 2024: (1)
CMS’ inclusion of reimbursement for CyPath® Lung on its 2024 clinical laboratory fee schedule; (2) the hiring of
our new National Director of Sales, Dallas Coleman, who is experienced and well respected in the pulmonary field; and (3) marketing materials
for the newly branded CyPath® Lung that emphasize our test’s ability to assist physicians with next steps in patient
care.
The
next step in our marketing plan is expansion into the Southwest market area in 2024 followed by a staged nationwide expansion of sales
and marketing beginning later in 2024. In addition to introducing pulmonologists, family practitioners, and other providers to CyPath®
Lung, we are selling CyPath® Lung tests to the Department of Defense, which represents a significant potential market
for CyPath® Lung. Phase 2 of our business plan anticipates entering the EU market with CyPath® Lung as
a CE-marked IVD test with sales in the Netherlands, followed by a staged EU expansion. Phase 3 of our business plan focuses on the marketing
of an FDA-cleared CyPath® Lung test, beginning with a pivotal clinical trial in the U.S. Toward that end, we intend to
voluntarily seek FDA clearance of the CyPath® Lung as a Class II IVD medical device for the detection of lung cancer.
We have designed our pivotal trial with guidance from our Clinical Research Organization (“CRO”), Courante Oncology, and
we are preparing a pre-submission that will be submitted to the FDA for review and feedback. We anticipate a three-year diagnostic trial
including an 18-month patient enrollment of approximately 1,800 patients. Similar to the test validation trial, the planned pivotal trial
will analyze flow cytometry and patient data including (1) the proportion of cells with a high ratio of high TCPP fluorescence intensity
over cell size; (2) the proportion of cells with an intermediate ratio of fluorescence intensity caused by the viability dye (FVS510)
over cell size; (3) the proportion of cells that were CD206 negative but positive for one or more of the following markers: CD66b (granulocytes),
CD3 (T cells), and CD19 (B cells); and (4) patient age. Patient enrollment is scheduled to begin in 2024 at up to 20 collection sites.
Assuming the study is successful, we intend to submit a de novo classification request to the FDA within six months of study completion.
Phase 4 of our business plan accelerates the market presence of CyPath® Lung in countries in Asia, Eastern Europe, and
Australia after obtaining FDA marketing authorization.
At
each phase of commercialization, we plan to develop messaging and marketing programs, including key convention attendance, digital marketing,
social media presence, and advertising, to create an “inbound” lead generation mechanism that delivers our message to our
target audience. In addition, we plan to collaborate with key opinion leaders (“KOLs”) to expand our pool of third-party
experts and speakers. We will provide support and collateral materials, including posters, presentations, videos, and peer-reviewed papers,
to our KOLs who will present data and their experience with CyPath® Lung at key meetings. This content can be shared across
platforms, including websites and sales tools, and will be used as references to support our product claims as well as sales and marketing
efforts to physicians, reference laboratories, and patients. We will also work with lung cancer advocacy groups throughout all phases
to support the message that routine screening can save lives by diagnosing cancer at an early stage.
The
Competition for CyPath® Lung
CyPath®
Lung has not been tested directly against its competitors’ products, but a comparison of the published performance numbers
suggests CyPath® Lung is among the highest performing tests on the market. Furthermore, CyPath® Lung is
noninvasive – not even requiring a needle stick – and cost effective, and processing and analysis procedures are easy to
perform.
Published
data and the results of clinical trials allow us to group lung cancer diagnostic tests into three categories: (1) balanced tests;( 2)
rule-out tests, and (3) rule-in tests. Balanced tests aim at excluding patients without cancer from unnecessary follow-up diagnostic
procedures and detecting patients with early-stage cancer who can proceed to more aggressive procedures to confirm diagnosis. Rule-out
tests aim to exclude patients without cancer from unnecessary follow-up procedures with high accuracy (if the test provides a “negative”
result), but among the remainder of patients who do not receive an unambiguous negative result, there is still uncertainty about who
has cancer and who does not. Cancer patients for whom time is of the essence are included in this group of patients still in uncertainty.
The patient can lose precious time with a rule-out test. Rule-in tests aim to identify patients with cancer but in doing so may identify
many people without cancer as positive. Therefore, rule-in tests have a low positive predictive value.
We
believe that balanced tests, like CyPath® Lung, can be the most cost effective. Those that perform well are most useful
to a physician and his or her patient because they provide the most information, allowing a quicker decision on what follow-up path to
choose: whether to move forward with more aggressive follow-up procedures (i.e., in the case of CyPath® Lung, if the test
reveals a “likely” or “highly likely” cancer result) or to follow a more conservative approach (i.e., when the
CyPath® Lung test reveals an “unlikely” or “very unlikely” cancer result).
We
completed a competitive analysis in 2022 of 67 companies that published research sufficient to provide a scientific basis for evaluation.
We found only seven tests, including CyPath® Lung, that represent a balanced test for early lung cancer detection and
have advanced to the point that there is sufficient data for evaluation. One test is sold by two companies: one from the U.S. and one
from China. In the U.S., the test is called Lung LB (sold by LungLife AI) and is now on the market. LungLB is a FISH-based test that
requires a significant amount of experience to conduct. Four companies, each selling unique tests for early lung cancer detection, conducted
their studies on a population that does not match the high-risk population for which the test is intended. Their clinical data, therefore,
is not necessarily representative of the results that would be achieved in the population of patients who actually will use the test.
The remaining balanced test, ProLung, is from IONIQ Sciences. The test requires an expensive machine to measure transcutaneous bioconductance.
The test is not on the market at this time.
Delphi’s
First Look was recently launched to assist in determining whether a person should be screened by LDCT. While CyPath Lung®
is positioned to help diagnose lung nodules in patients who have already undergone screening by LDCT, First Look is intended to be used
prior to LDCT. As such, this test may increase lung cancer screening uptake and potentially increase the need for CyPath Lung®.
We
found two rule-out tests on the market. Both REVEAL, offered by MagArray, and Nodify-XL2, offered by Biodesix, are rule-out tests, meaning
the tests aim to exclude patients without cancer. The REVEAL test is a blood test intended for patients with indeterminant nodules. In
their 97-patient clinical validation trial, only patients with an intermediate risk of cancer, based either on a physician’s judgement
or a clinical model, took part. This requirement led to 30% of high -risk patients being excluded at the onset of their analysis. In
addition, the positive predictive value of the REVEAL test was 13.5% as compared to CyPath® Lung’s positive predictive
value of 43.2%. Importantly, no patients were excluded from the CyPath® Lung test. The tests had negative predictive values
of 98% and 97.8%, respectively. The second rule-out test, Nodify-XL2, is used only by people with a pre-test probability of cancer less
than 50%. As with the REVEAL test, a large number of patients were excluded from analysis. In the case of Nodify-XL2, about 55% of patients
with lung nodules that physicians considered indeterminate, namely lung nodules sized between 8-30 mm, were excluded from the study.
In addition, Nodify XL-2 reported an AUC of 0.62 (unacceptable) and 0.76 (acceptable) for their two clinical trials, as compared to CyPath®
Lung with an AUC of 0.89 and 0.90 in two independent study groups (excellent).
Finally,
the Percepta nasal swab test offered by Veracyte is not widely available and is seeking a reimbursement code. The test classifies patients
in low- and high-risk categories, or for those whose results are unclear, an intermediate category. Test performance is different in
each risk category. In a recently published paper of the test validation trial, the sensitivity and specificity for low-risk classification
was 97% and 40%, respectively, with those at low risk having an 8% calculated risk of having a malignancy. The sensitivity and specificity
for the high-risk classification was 57% and 92%, respectively, and those patients who were put into the high-risk category had a 90%
risk of a malignancy. One of the limitations of this study is that the participants in the validation trial had a cancer prevalence of
54% as compared to the overall high-risk population that has an estimated lung cancer prevalence of 1.1%, according to the National Lung
Cancer Screening Trial. Therefore, we believe the nasal swab test’s performance may suffer when the classifier is tested on more
realistic cohorts with a cancer prevalence lower than 10%. Although it is a patient-friendly test, a major limitation of the test is
that nearly half of all patients who took part in the validation trial could not be classified as either low- or high-risk; instead,
they are considered “intermediate risk” with a 50:50 chance of having cancer. Thus, in nearly half of the patients who received
the Percepta nasal swab test, the results would not help advance the diagnostic process. In fact, for those patients in this indeterminate
category who do have cancer, valuable time in diagnosis may be lost.
We
believe there are many reasons why CyPath® Lung is a superior test when compared to its competitors. First, lung sputum
is an excellent medium for early lung cancer detection because sputum is in close contact with the tumor and pre-cancerous areas that
shed cancer and pre-cancerous cells directly into the sputum, can be obtained noninvasively, and can be transported easily. Moreover,
sputum contains immune cell populations in reaction to the presence of a tumor. Second, our proprietary technology is straightforward.
Our CyPath® Lung platform technology is not a molecular test and does not collect genetic material that requires immediate
processing. CyPath® Lung uses well-established flow cytometry techniques to investigate cells contained in the sputum
for characteristics that indicate the likelihood of lung cancer. Sample processing is straightforward, and laboratory technicians can
be easily trained. Reagents used by the test are widely available. Data acquisition and analysis is fully automated, allowing for non-biased,
efficient test results. Third, CyPath® Lung has shown high specificity and sensitivity that is similar to far more invasive
and more expensive procedures currently used to detect lung cancer. Fourth, CyPath® Lung is cost effective, with a Medicare
reimbursement code billable to both government and private insurance carriers. Fifth and as important as any of our test’s benefits,
CyPath® Lung is patient friendly, providing at-home sample collection that is noninvasive and offers particular benefit
during a public healthcare crisis like the coronavirus pandemic.
Research
and Development Activities
We
are continuing our research and development activities pertaining to diagnostics that include multiple studies we believe will support
FDA final approval of CyPath® Lung, which we will seek after completing the pivotal trial. With support from the DOD,
we are also conducting research advancing the development of CyPath® Lung for detection of COPD and a test for use with
bronchoalveolar lavage fluid (BAL) as a companion test to bronchoscopy. With regard to therapeutic research, we continue our experiments
focused on establishing proof-of-concept for our discovery that the silencing or knockdown of two genes that each encode a cell surface
receptor result in cancer death without perceived harm to healthy cells.
Other
Diagnostic Applications for the CyPath® Platform
We
expect to expand our platform technology to detect and monitor other lung diseases. Our research is conducted, in part, in collaboration
with Brooke Army Medical Center in San Antonio, Texas, and partially funded by the DOD.
Chronic
Obstructive Pulmonary Disease and Other Diseases of the Lung.
The
respiratory diagnostics market was valued at $5.6 billion in 2023 and is expected to reach $8.2 billion by 2029, according to a market
research study published by Research and Markets in November 2023. The World Health Organization reports that COPD is the third
leading cause of death in the world, causing nearly 3.23 million deaths in 2019. The disease is characterized as an abnormal inflammatory
response and airflow obstruction that cannot be fully reversed. Early detection allows for the use of therapies when the disease is less
severe, which slows the progression of the disease. We plan to build on our expertise in using sputum as a sample for flow cytometric
analysis to develop a test to detect COPD at an early stage and monitor for signs of impending exacerbations before clinical signs occur.
CyPath® Lung’s flow cytometry platform provides for identification of cell populations and other parameters of disease
in the lung. Our test illuminates the microenvironment of the lung. We believe that our flow cytometric test can be designed to identify
other lung diseases, such as COPD and asthma, using antibodies that characterize cell populations in sputum specific to the disease.
