The
Company has generated material operating losses since inception. The Company has had recurring net losses since inception which has resulted
in an accumulated deficit of $85,361,229$88,427,246 and $82,450,781$85,361,229 as of December 31, 20242025 and 2023,2024, respectively, including net losses of $2,910,448$3,066,017
and $2,894,753$2,910,448 for the years ended December 31, 20242025 and 2023.2024, respectively. Historically, the Company has relied upon investor funds
to maintain its
operations and develop its business. The Company needs to raise additional capital from investors for working capital
as well as business
expansion, and there is no assurance that additional investor funds will be available on terms acceptable to the
Company, or at all.
If the Company is unable to unable to obtain additional financing to meet its working capital requirements, the Company
likely would
cease operations.

The
continued deployment of precision radionuclide therapy products and a worldwide regulatory approval effort will require additional resources
and personnel. The principal variables in the timing and amount of spending for the brachytherapyprecision radionuclide therapy products in the next
12 to 24 months will be the FDA’s
classification of the Company’s brachytherapyprecision radionuclide therapy products as Class II or
Class III devices (or otherwise) and any requirements for
additional studies,studies which may possibly include clinical studies. Thereafter,
the principal variables in the amount of the Company’s
spending and its financing requirements would be the timing of any approvals
and the nature of the Company’s arrangements with
third parties for manufacturing, sales, distribution and licensing of those products
and the products’ success in the United States
of America (“U.S.”, or the “United States”) and elsewhere. The Company intends to fund its activities

The Company has repeatedly attempted to gain FDA approval for the IDE and obtain clearance for its precision radionuclide therapy Y-90 RadioGelTM device, but no assurances have been received.
The next attempt to submit an IDE request is targeted to be submitted in the near future buttressed by additional animal and human therapy communicated using the recommend format of a well-respected FDA advisor.
TheOn
Company has been working with the FDA to obtain clearance for its precision radionuclide therapy Y-90 RadioGelTM device, but
no assurances have been received. On December 23, 2014, the Company announced that it submitted a de novo application to the FDA
for marketing clearance for its patented
Y-90 RadioGelTM device pursuant to Section 513(f)(2) of the U.S. Food, Drug and Cosmetic
Act (the “Act”).
In June 2015, the FDA notified the Company the de novo application was not granted. In February
2014, the FDA found the same device
under Section 510(k) of the Act not substantially equivalent and concluded that the device is classified
by statute as a Class III medical
device, unless the device is reclassified. The Company is seeking reclassification of the product to
Class II. If the Company is successful
in seeking reconsideration of the Company’s de novo application, as a regulatory
matter, the device could be on an easier
and faster path to market in the United States. However, there would still be the requirements
to complete the in vitro and in vivo testing,
and then some human clinical trials. That testing date is submitted in a de novo pre-market
application and if accepted we could then
go to market. As a practical matter, the Company would still need to secure funding and commercial
arrangements before marketing could
commence. If the de novo application is declined and if the Company obtains funding to permit
it to continue operations, the Company
will explore steps toward seeking approval for the device as a Class III medical device. Generally,
the time and cost of seeking approval
as a Class III medical device is materially greater than the time and cost of seeking approval
as a Class II medical device. If the Company
seeks approval as a Class III device, human clinical trials will be necessary. Generally,
human trials for Class III products are larger,
of longer duration and costlier than those for Class II devices.
To
mitigate this risk Dr. Korenko has been working with two internal candidates with the potential to seamlessly assume authority. Both
David SwanbergSwanberg, Chief Operating Officer of the Company, and Brad Weeks, currentPresident active consultants toof the Company with broad responsivities,Company, have been identified as high potential
candidates to succeed Dr. Korenko or to assume senior positions, although no formal arrangement has been reached. The Company Board would
make the final appointment.Korenko. See “Directors, Executive Officers and Significant Consultants” on page 29.36.
The
Company’s revenues relate to their commercializing of its products and procedures performed. The Company had $27,995$68,379 and $19,500$27,995
in operating revenues, net of discounts, forand the years ended December 31, 20242025 and 2023,2024, respectively, as we have commenced sales of

The Company currently relies on a single contract manufacturer in Texas (previously IsoTherapeutics, acquired by Telix Pharmaceuticals in April 2024) for the production of RadioGel® and IsoPet®, including the yttrium-90 (Y-90) phosphate particles and their integration with sterile hydrogel to create individual patient doses. This arrangement has been identified as a risk factor in prior corporate filings due to potential single-source vulnerabilities.
To mitigate these risks and support scalable growth, the Company is actively diversifying its manufacturing base. For the domestic side, Vivos has signed a contract for production space at the Applied Process Engineering Laboratory (APEL) in Richland, Washington, where the Company will serve as the manufacturer of record. Equipment has been ordered, installation is underway, and licensing applications have been submitted to enable operational readiness.
For international production, the Company is in ongoing discussions with experienced radiopharmaceutical contract manufacturers in India, aligned with the activities of Vivos Scientific India LLP (VSIL), to establish a second facility. These efforts aim to reduce shipping costs, improve logistical efficiency, and expand global market access for both RadioGel® (human) and IsoPet® (veterinary) therapies.
The Company’s strategic target is to have one domestic production facility (with Vivos as manufacturer of record) and one international production facility operational in 2026. Production with the existing Texas contract manufacturer will continue through Q2 2026 to ensure continuity during the transition.
In parallel, the Company has secured alternate suppliers for the hydrogel polymer component (PrecisionGel™), including Akina, Inc. (engaged in 2021 and expanding to supply sterilized hydrogel) and SciPoly. For particle production, Vivos is actively assessing both domestic and international candidates to develop additional alternatives beyond the current arrangement. These diversification steps—announced in the February 17, 2026, press release—address sole-source dependencies, accommodate increasing demand (particularly in the IsoPet® division), and support broader commercialization following regulatory advancements.
IsoTherapeutics
is our sole particle manufacturing contractor. Vivos now has alternate suppliers for its hydrogel and is actively engaged is selecting
an alternate supplier for the particle production. Both domestic and internation candidates are being assessed.
As
a public company, the Company is subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, and the Sarbanes-Oxley
Act of 2002. The Company’s management is required to evaluate and disclose its assessment of the effectiveness of the Company’s
internal control over financial reporting as of each year-end, including disclosing any “material weakness” in the Company’s
internal control over financial reporting. A material weakness is a control deficiency, or combination of control deficiencies, that
results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented
or detected. As a result of its assessment, management has determined that there is a material weakness due to the lack of segregation
of duties and, due to this material weakness, management concluded that, as of December 31, 20242025 and 2023,2024, the Company’s internal
control over financial reporting was ineffective. This material weakness has the potential of adversely impacting the Company’s
financial reporting process and the Company’s financial reports. Because of this material weakness, management also concluded that
the Company’s disclosure controls and procedures were ineffective as of December 31, 20242025 and 2023.2024. The Company needshas toengaged hirethe
services additional
qualifiedof both internal accounting personneland tax providers to resolve this material weakness. The Company also will need to expend any additional
resources and efforts
that may be necessary to establish and to maintain the effectiveness of the Company’s internal control over
financial reporting
and disclosure controls and procedures.

(5v) initiate regulatory approval processes outside of the United States.
Consolidation
The Company has a relationship with Vivos India, which is considered a variable interest entity (VIE) under the guidance in ASC 810, Consolidations. A VIE is an entity in which the equity investors do not have sufficient equity investment at risk or lack the characteristics of a controlling financial interest. The Company evaluates the interests in such entities to determine whether it is the primary beneficiary and therefore required to consolidate the VIE in its financial statements.
The Company has determined that it is the primary beneficiary of Vivos India because it has both (i) the power to direct the activities that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Accordingly, the assets, liabilities, and results of operations of Vivos India will be included in the Company’s consolidated financial statements. As of December 31, 2025, the Company is still waiting on regulatory approval in India to commence operations.
The
preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at
the date of financial statements and the reported amountsamount of revenuesrevenue and expensesexpense during the reporting period. Estimates the Company considers
considers include criteria for stock-based compensation expense, and valuation allowances on deferred tax assets. Actual results could
differ from
those estimates.
In
May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”)
No. 2014-09, Revenue from Contracts with Customers (Topic 606). This standard provides a single set of guidelines for revenue recognition
to be used across all industries and requires additional disclosures. The updated guidance introduces a five-step model to achieve its
core principle principal
of the entity recognizing revenue to depict the transfer of goods or services to customers at an amount that reflects
the consideration
to which the entity expects to be entitled in exchange for those goods or services. The Company adopted the updated
guidance effective
January 1, 2018 using the full retrospective method.
Under
the FASB’s Accounting Standards Codification (“ASC”) Topic 606, in order to recognize revenue, the Company is required
to identify an approved contract with commitments to preformperform respective
obligations, identify rights of each party in the transaction
regarding goods to be transferred, identify the payment terms for the goods
transferred, verify that the contract has commercial substance
and verify that collection of substantially all consideration is probable.
The adoption of ASC 606 did not have an impact on the Company’s operations or cash flows.
The
Company in 2024 also implemented a license program for clinics that pay for certification to perform these therapies. These revenues
are recognized upon the certification being completed. DuringIn addition, due to a pricing discount from the yearmanufacturer, endedthe DecemberCompany 31,sold

Segment Reporting
The Company follows Financial Accounting Standards Board issued Accounting Standards Update 2023-07 (“ASU 2023-07”) for its segment reporting. ASU 2023-07 requires more detailed information about reportable segments and expenses including the requirement to disclose qualitative information about factors used to identify reportable segments and quantitative information about profit and loss measures and significant expense categories. The Company has not yet begun generating significant revenue from its planned principal operations and operates as a single reportable segment. The revenue associated with the services that the clinics perform by way of treatments and the licensure of these clinics are not considered two distinct segments for the years ended December 31, 2025 and 2024, respectively. The benefit the clinics get by being licensed will assist in increased revenues associated with the treatments being administered. The chief operating decision maker is the Company’s chief executive officer who assesses performance based on total expenses, cash flows, and progress made in the Company’s ongoing development efforts. With the formation of the VIE, Vivos India, and the fact that this is consolidated for financial reporting purposes, the activities of Vivos India are a defined segment for geographical purposes. As of December 31, 2025, the Company is still waiting on regulatory approval in India to commence operations. All of the Company’s long-lived assets as of December 31, 2025 are located in the United States.

engagedfocused inon the development of its yttrium-90 (“Y-90”) based precision radionuclide therapy devices. ThisThese includesinclude RadioGel®
Precision Radionuclide Therapy™ (Human Division) for treatingthe treatment of solid tumors and positive surgical margins in humanshumans, and IsoPet®
(Animal Division) for treatingthe treatment of solid tumors and positive surgical margins in animals. The Company also sells PLGA-g-PEG polymers and PrecisionGel™,
a hydrogel
polymer platform designed for deliveringthe delivery of active pharmaceutical ingredients and therapeutic agents. A prominent team of radiochemists, scientists,
and engineers, collaborating with strategic partners, including national laboratories, universities, and private corporations, lead the
Company’s development efforts. The Company’s overall vision is to globally empower physicians, medical researchers, veterinarians,
and patients by providing them with new isotope technologies and advanced polymer solutions that offer safe and effective treatments
for cancer in both humans and animals.
In 2013, the United States Food and Drug Administration (“FDA”) issued the determination that RadioGel® is a device for human therapy for non-resectable cancers. In January 2018, the FDA Center for Veterinary Medicine classified IsoPet® (formerly RadioGel®) as a medical device for veterinary use. As a result, veterinary medical devices do not require premarket approval or notification for commercial distribution in the United States, provided the product is safe, effective, properly labeled, and compliant with applicable regulations. The Company markets RadioGel® as IsoPet® for veterinary use to distinguish it from the human therapy product.
The Company’s IsoPet® Solutions division was established in May 2016 to focus on the veterinary oncology market. The Company has collaborated with multiple university veterinary hospitals and national laboratories on IsoPet®/RadioGel® testing and development, including Washington State University, Colorado State University, the University of Missouri, and Johns Hopkins University. These studies demonstrated that the Y-90 particles remain localized at the injection site with minimal distribution to surrounding tissues.
Commencing in July 2019, the Company recognized its first commercial sale of IsoPet®. Since that time, IsoPet® has been used to treat solid tumors and positive surgical margins in companion animals.
RadioGel® is an injectable yttrium-90 (Y-90) particle-gel designed for precision radionuclide therapy. It consists of a hydrogel that is liquid at room temperature and gels upon reaching body temperature after injection into a tumor. The hydrogel contains small Y-90 phosphate particles that become locked in place, delivering localized beta radiation to the target tissue while minimizing exposure to surrounding healthy tissue. The Y-90 isotope has a half-life of 2.7 days.
In
2013, the United States Food and Drug Administration (“FDA”) issued the determination that RadioGel®
is a device for human therapy for non-resectable cancers in humans. This should result in a faster path than a drug for final approval.
In
January 2018, the Center for Veterinary Medicine Product Classification Group ruled that RadioGel® (now marketed as IsoPet® for
veterinary use) should be classified as a medical device for animal therapy, initially specified for feline sarcomas and canine soft
tissue sarcomas. Additionally, after legal review, the Company believes that this device classification from the FDA Center for Veterinary
Medicine is not strictly limited to canine and feline sarcomas but may extend to a broader population of veterinary cancers, including
all or most solid tumors in animals. As veterinary medical devices do not require premarket approval or notification (such as 510(k)
or PMA) for commercial distribution in the United States, IsoPet® is authorized for marketing and commercial distribution following
this classification, provided the product is safe, effective, properly labeled, and compliant with applicable laws and regulations. The
FDA does not exercise premarket authority over veterinary devices, and manufacturers bear responsibility for ensuring ongoing compliance.
This classification enables the commercial distribution of IsoPet® for treating solid tumors in animals.
Based
on the FDA’s recommendation, RadioGel® is being marketed as “IsoPet®” for use by veterinarians
to avoid any confusion between animal and human therapy. The Company already has trademark protection for the “IsoPet®”
name. IsoPet® and RadioGel® are used synonymously throughout this document. The only distinction between
IsoPet® and RadioGel® is the FDA’s recommendation that we use “IsoPet®”
for veterinarian usage, and reserve “RadioGel®” for human therapy. Historically, the Company’s primary
focus was on the development and marketing of Isopet® for animal therapy, through the Company’s IsoPet®
Solutions division. Over the last four years much effort has been directed to completing the testing require to obtain FDA approval for
an Investigational Device Exemption and to obtain approval for clinical trials in India.
The
Company’s IsoPet Solutions division was established in May 2016 to focus on the veterinary oncology market, namely engagement of
university veterinarian hospital to develop detailed therapy procedures to treat animal tumors and ultimately use of the technology in
private clinics. In January 2025 the Company restructured and aligned its internal resources and focused efforts to align with animal
therapy, human therapy, and recently other applications of its patented technologies.
The
Company has worked with five different national laboratories or university veterinarian hospitals on IsoPet®/RadioGel™
testing and therapy. Washington State University treated five cats for feline sarcoma and served to develop the procedures which are
incorporated in our label. They concluded that the product was safe and effective in killing cancer cells. Colorado State University
demonstrated the CT and PET-CT imaging of IsoPet®. The University of Missouri conducted an animal study to treat canine
sarcoma. Johns Hopkins University completed a study on VX2 Tumors in Rabbits. Every study confirmed that the Y-90 stayed at the injection
site with insignificant distribution outside that boundary.
Commencing
in July 2019, the Company recognized its first commercial sale of IsoPet®. A veterinarian from Alaska brought his cat with a re-occurrent
spindle cell sarcoma tumor on his face. The cat had previously received external beam therapy, but now the tumor was growing rapidly.
He was given a high dose of 400Gy with heavy therapy at the margins.
The
Company anticipates that any near-term profits, if any, will be derived from direct sales of RadioGel® (under the name
IsoPet®) and related services, and from certifying veterinary clinics to administer IsoPet Therapy. Until recently the
Company certified clinics at its own expense, but the demand has increased to the point that starting in 2025 the Company billed its
first clinic for the certification process. The Company has transitioned to “Volume Pricing” to stimulate broader interest
and adoption. With significant growth achieved in 2025—including a reported 1,200% year-over-year increase in administered therapies
and expansion of the certified clinic network—the Animal Therapy Division (IsoPet®) is positioned to reach breakeven status
in 2026, supported by ongoing profitability-focused initiatives, continued clinic expansion, and improved operational efficiency.
The
plan is to incorporate the data assembled from our work with Isopet® in animal therapy to support the Company’s
efforts in the development of our RadioGel™ device candidate, including obtaining approval from the FDA to market and sell RadioGel®
as a Class II medical device. RadioGel® is an injectable particle-gel for Precision Radionuclide Therapy radiation treatment
of cancerous tumors in people and animals. RadioGel® is comprised of a hydrogel, or a substance that is liquid at room
temperature and then gels when reaching body temperature after injection into a tumor. In the gel are small, less than two microns, Y-90
phosphate particles. Once injected, these inert particles are locked in place inside the tumor by the gel, delivering a very high local
radiation dose. The radiation is beta, consisting of high-speed electrons. These electrons only travel a short distance so the device
can deliver high radiation to the tumor with minimal dose to the surrounding tissue. Optimally, patients can go home immediately following
treatment without the risk of radiation exposure to family members. Since Y-90 has a half-life of 2.7 days, the radioactivity drops to
5% of its original value after ten days.
In
20212021, the Company modified itsthe Indicationproposed indication for Useuse fromfor skin cancerRadioGel® to cancerousfocus tissue oron solid tumors pathologically associated
with with

are not surgical candidates or who have declined surgery, or patients who require post-surgical
remnant ablation (for example, after prior incomplete radioiodine therapy). Papillary thyroid carcinoma belongs to the general class
of head and neck tumors for which tumors are accessible by intraoperative direct needle injection. The Company’s Medical Advisory
Board felt that demonstrating efficacy in clinical trials with this new indication provided a more efficient pathway to regulatory clearance.surgery.
In the third quarter ended September 30, 2025, the Company strengthened its leadership team with the appointment of Brad Allan Weeks as President (effective September 1, 2025) and David J. Swanberg as Chief Operating Officer (effective September 15, 2025).
On
September 17, 2025, the Board of Directors of the Company approved the creation of Vivos Scientific India LLP (“VSIL”), a
wholly owned separate legal entity in India. Vivos India was formally established in September 2025 (with incorporation completed and
government approvals finalized shortly thereafter), expanding the Company’s strategic initiatives in the region. The primary objectives
include establishing the Company’s first international manufacturing center for RadioGel® and IsoPet®, advancing expanded
human therapy demonstrations and clinical trials (including ongoing patient treatments initiated in December 2024 and progress toward
DCGI regulatory clearance for larger-scale trials), pursuing commercialization of therapies for both humans and animals in India, and
generating additional human trial data to support the Company’s regulatory processes with the U.S. Food and Drug Administration
(FDA), such as the planned Investigational Device Exemption (IDE) submission in early 2026. As of February 2026, discussions continue
with experienced radiopharmaceutical contract manufacturers in India to support the establishment of this international production facility,
with a target for operational status by the end of 2026 to reduce shipping costs, enhance logistical efficiency, and facilitate broader
global access to the Company’s precision radionuclide therapies.
In
the third quarter ended September 30, 2025, the Company strengthened its leadership team to support accelerating growth in both the U.S.
and international markets by appointing Brad Allan Weeks as President (effective September 1, 2025) and David J. Swanberg as Chief Operating
Officer (effective September 15, 2025). These appointments reflect the Company’s strategic response to rapid expansion, particularly
in the IsoPet® Animal Therapy Division—which achieved a reported 1,200% year-over-year increase in administered therapies from
2024 to 2025—and ongoing advancements in RadioGel® human therapy development, including progress toward FDA Investigational
Device Exemption (IDE) submission and the establishment of Vivos Scientific India LLP in September 2025. The new executive roles are
designed to enhance operational efficiency, scale commercial activities, drive clinic certifications and therapy adoption, and position
the Company for sustained growth and potential profitability in the Animal Therapy Division by 2026.
These
enhancements maintain the intended use while maximizing the submission’s clarity, completeness, and alignment with Agency expectations.
These recommendations required substantial effort to incorporate into our next submission.

cash needs closely and explore additional financing
avenues as it progresses toward regulatory milestones and operational profitability.
Following
receipt of required regulatory approvals (including potentialthe FDAFDA’s July 2026 IDE clearanceapproval for human trials) and necessary financing
to support
working capital and expansion, the Company plans to transition to greater operational control over key aspects of its supply

Research
and development of the Company’s precisionPrecision radionuclideRadionuclide therapyTherapy™ product line has been funded primarily with proceeds from
the sale of equity
and debt securities, including from theprior Regulation A+ Offerings. The Company requires additional funding of approximately
$3.0 million
annually to maintain its current level of operating activities. The Company continues to make progress with its IsoPet®
animal therapy division, narrowing the profitability gap with the goal of eventually operating it as a self-sustaining, standalone business.
Over the next 36 months, the Company believes it will require approximately $9.0 million in
additional capital to: (i) fund the FDA approval process to conductongoing
FDA-approved human clinical trialsprogram and related activities; (ii) conduct Phasethe I,Early pilot,Feasibility study, subsequent pivotal trials, and
other clinical trialsactivities;
(iii) activate several regional clinics to administer IsoPet® across the U.S.United States; (iv)
create an independent production center
within the current production site to createserve as a template for future international manufacturing;
and (v) initiate regulatory approval
processes outside of the United States. The proceeds raised from the Regulation A+ Offerings were used to fund this development and will
be used to continue such development efforts.
Proceeds raised from previous Regulation A+ Offerings have been used to fund these development efforts and proceeds from the March 2026 Regulation A+ Offering will be used to continue such development.
The continued deployment of Precision Radionuclide Therapy™ products and the Company’s worldwide regulatory approval efforts will require additional resources and personnel. The principal variables in the timing and amount of spending over the next 12 to 24 months will be the progress, enrollment, and results of the FDA-approved Early Feasibility IDE human feasibility study at Mayo Clinic in Jacksonville, FL, the transition to subsequent pivotal trials, ongoing and planned studies in India through Vivos Scientific India LLP, any additional FDA or international regulatory requirements, and broader clinical and manufacturing scale-up activities.
The
continued deployment of precision radionuclide therapy products and a worldwide regulatory approval effort will require additional resources

Clinical
experience at universities and Vista demonstrates IsoPet®’s effectiveness in ablating cancer tissue near injection sites, performing
best in early-stage tumors before metastasis. Later-stage cancers are more challenging due to poorly defined tendrils, increasing recurrence
risk.
Johns
Hopkins University Veterinary Clinical Trials Network (Baltimore, MD) is now a certified IsoPet® regional clinic, holding the required
radioactive material license and completing training. This partnership supports high-quality data collection across cancer types for
publication in leading journals, boosting awareness and acceptance in the veterinary oncology community. Johns Hopkins recently completed
a VX2 tumor study in rabbits, confirming IsoPet® (and by extension RadioGel®) safety, with hydrogel retention at the injection
site, activity decay curves, validation of Instructions for Use and Injection Guidance Table, and insights for refining human lymph node

The Company continues to see increased patient adoption of IsoPet® therapy, which is driving higher treatment volumes, growing revenue, and expanded shipments. Shipments from the Company’s new in-house production facility in Richland, Washington are expected to commence in the near term. This increased scale is allowing the implementation of operational efficiencies and supporting progress toward narrowing the profitability gap in the Animal Therapy Division.
The
division shifted from data collection to commercialization in 2024–2025, refining pricing for affordability, aligning production
with patient bookings to reduce costs, and implementing volume pricing. Starting Q1 2026, profitability initiatives include billing clinics
for certification and continued network expansion.
Objectives
include adding several more regional clinics in 2026 (with interested parties in the pipeline) and participating in at least four conferences
annually to promote IsoPet® for small animal and equine tumors. The Veterinary Medicine Steering Board advises patient acquisition
strategies. This nationwide growth supports the goal of breakeven in the Animal Therapy Division in 2026.
In
November 2020 the Company submitted a request for a Breakthrough Device Designation. Ultimately, this was denied, but the FDA acknowledged,
“The FDA does believe that RadioGel™® meets criterion #2a: Device represents breakthrough technology. Your device
does does
meet this criterion because it is a novel application of a precision radionuclide therapy device outside of the liver.”
More More
importantly, the process resulted in a rapid review of our existing data and approach. It led to a redirection of our efforts on
writing writing
the Investigational Device Exemptions (“IDEs”) and saved the Company much time in the review of that future
application.
The
FDA was supportive and had suggested this Q-Submission path for rapid turnaround and dialog. The Mayo Clinic physicians did an excellent
job presenting the need for Radiogel™RadioGel® to treat recurrent thyroid cancer and to answer a range of questions from the new
new FDA review team. The FDA provided many helpful suggestions on a range of subjects from labeling to dosimetry to the Mayo Clinic protocol
for clinical testing, and the need for some additional specific testing. They suggested having another Q-Sub Review and conference call
dedicated to the details of the dosimetry calculations.
We held another pre-submission meeting with the FDA on October 17, 2022 to obtain detailed feedback on the proposed VX-2/Rabbit Animal Test Plan and to submit the Risk Management Report (“RMR”). The RMR analyzed all hypothetical scenarios and concluded that RadioGel® is inherently safe.
After
providing additionadditional information to the FDA on December 18, 2023, the FDA classified us as a Breakthrough device to our proposed Indication
for Use.
In July 2025 we applied for FDA IDE with an application approval containing new India human therapy data. In FDA August 2025 the FDA declined approval based on their detailed questions/concerns. In November 2025 we participated in a Pre-Submission meeting focused on sterilization to address their comments confirming completion of container closure integrity testing and to introduce the Agency to the Company’s enhanced Electron Beam (E-Beam) sterilization process for the RadioGel® hydrogel to determine their reaction and recommendations.
The Company received U.S. FDA approval of its Early Feasibility Investigational Device Exemption (IDE) in July 2026, enabling initiation of the first-in-human clinical feasibility study for RadioGel® at Mayo Clinic in Jacksonville, FL. Extensive work with regulatory consultants, integration of human clinical data from India, reformatted pre-clinical information, and strong veterinary safety outcomes from IsoPet® (over 100 therapies with zero reportable serious adverse events) strengthened the submission. This approval, building on the FDA’s Breakthrough Device Designation, positions the Company to advance human clinical trials. This version fully updates the outdated “resubmitted… remains in review” language to reflect the current approved status while maintaining a professional tone suitable for a 10-Q or corporate disclosure.
Currently,
the IDE is in preparation under this expert’s guidance. The Company is positioned to incorporate final FDA input and submit the
complete IDE application in the near term (targeted by the end of the first quarter or in April 2026). This expert’s proven ability
to present complex IDE data in a format that this specific review panel can easily digest and understand has strengthened the submission,
alongside integration of newly available human clinical data, reformatted pre-clinical information, and leveraging veterinary outcomes
from IsoPet® (over 100 therapies with zero reportable serious adverse events). The Company remains encouraged by the constructive
ongoing dialogue with the FDA and is strongly positioned for IDE approval to advance human clinical trials.
The
Medical Advisory Board (“MAB”) selected 18 applications for RadioGel™®, each of which meet the criteria
described described
above. This large number confirms the wide applicability of the device and defines the path for future business growth. The
Company’s Company’s
application establishes a single Indication for Use - treatment of cancerous tissue or solid tumors pathologically associated
with locoregional
papillary thyroid carcinoma and recurrent papillary thyroid carcinoma.
Radiogel™®
Device Designation:
In
2014, the Company submitted a presubmission (Q130140) to obtain FDA feedback about the proposed product. The FDA requested that the Company
file a request for designation with the Office of Combination Products (RFD130051), which led to the determination that RadioGel™®
is a device for human therapy for non-resectable cancers, which must be reviewed and ultimately regulated by the Center for Devices and
Radiological Health (“CDRH”). The Company then submitted a 510(k) notice for RadioGel™® (K133368), which
was was
found Not Substantially Equivalent due to the lack of a suitable predicate, and RadioGel™® was assigned to the Class
III product
code NAW (microspheres). Class III products or devices are generally the highest risk devices and are therefore subject to
the highest
level of regulatory review, control, and oversight. Class III products or devices must typically be approved by FDA before
they are marketed.
Class II devices represent lower risk products or devices than Class III and require fewer regulatory controls to
provide reasonable
assurance of the device’s safety and effectiveness. In contrast, Class I products and devices are deemed to
be lower risk than
Class I or II, and are therefore subject to the least regulatory controls.
A
pre-submission meeting (Q140496) was held with the FDA on June 17, 2014, during which the FDA maintained that RadioGel™®
should should
be considered a Class III device and therefore subject to pre-market approval. On December 29, 2014, the Company submitted a de
novo novo
petition for RadioGel™® (DEN140043). The de novo petition was denied by the FDA on June 1, 2015, with the
FDA providing
numerous comments and questions. On September 29, 2015, the Company submitted a follow-up pre-submission informational
meeting request
with the FDA (Q151569). This meeting took place on November 9, 2015, at which time the FDA indicated acceptance of the
Company’s Company’s
applied dosimetry methods and clarified the FDA’s outstanding questions regarding RadioGel™®. Following
the November 2015
pre-submission meeting, the Company prepared a new pre-submission package to obtain FDA feedback on the proposed testing
methods, intended
to address the concerns raised by the FDA staff and to address the suitability of RadioGel™® for de
novo reclassification.
This pre-submission package was presented to the FDA in a meeting on August 29, 2017. During the August 2017
meeting, the FDA clarified
their position on the remaining pre-clinical testing needed for RadioGel™®. Specifically, the
FDA addressed proposed dosimetry calculating
techniques, dosimetry distribution between injections, hydrogel viscoelastic properties,
and the details of the Company’s proposed
animal testing.
The Company’s Precision Radionuclide Therapy™ platform, including its RadioGel® device (marketed as IsoPet® for veterinary use), utilizes a proprietary injectable hydrogel containing Y-90 phosphate particles for localized treatment of solid tumors. Key attributes include:
RadioGel® is currently not approved for human use in the U.S. and is advancing through regulatory pathways, while IsoPet® is commercially available for veterinary oncology applications.
The
Company’s RadioGel™ device has the following product features:
Steps
from Production to Therapy
During 2025, the Company advanced plans to establish one domestic and one international production center to support expanded demand for IsoPet® and future RadioGel® requirements. Manufacturing is conducted under Good Manufacturing Practices (GMP). The proprietary hydrogel and Y-90 phosphate particles are produced in large batches. The Company has implemented a ready-to-use (RTU) pre-mixed formulation in standard vials, which improves cost efficiency, simplifies clinic handling and training, and reduces risks of spills or contamination. Shipments are made in specialized packaging via common carriers in compliance with applicable radioactive material transport regulations. The product is administered by direct intratumoral injection per Instructions for Use, with dosing and technique tailored to tumor size.
During
2025 the Company decided to expand its manufacturing capabilities and to target for on domestic and one international production center.
Several candidates were assessed.
Production
of the Hydrogel
RadioGel™
is manufactured with a proprietary process under ventilated sterile hood by following strict Good Management Practices (“GMP”)
procedures. It is made in large batches that are frozen for up to three months. When the product is ready to ship, a small quantity of
the gel is dissolved in a sterile saline solution. It is then passed through an ultra-fine filter to ensure sterility. An alternate process
of E-Beam sterilization was developed and verified. Limited GDA recommended testing will be conducted next year to obtain FDA approval
for human therapy.
