Added

On November 6, 2025, we disclosed the filing of a trademark application with the United States Patent and Trademark Office to protect the name CardioDialysisTM. The action reflects our intent to shift the previous therapeutic focus of Sigyn TherapyTM toward cardiovascular disease.

Added

This action provides us a pathway into a larger market opportunity, for which there is an FDA-approved device precedent that clinically demonstrates the ability of blood purification to reduce Major Adverse Cardiovascular Disease Events (MACE). As compared to our previously proposed treatment indications, we believe it will be significantly less burdensome to enroll cardiovascular disease subjects into pivotal efficacy studies that will be required for FDA market approval. Furthermore, we consider our potential value to the dialysis industry as a majority of their patients die from cardiovascular disease related events. Our previously proposed indications, which included the treatment of sepsis, drug-resistant bacterial infections, and life-threatening viruses will become downstream therapeutics opportunities.

On January 9, 2025, the Company initiated a Regulation D offering to sell up to 750,000 Units at a price of $5,000 per unit with each Unit consisting of one (1) $5,500 principal amount convertible debenture (convertible at two dollars ($2.00) per share into the Company’s common stock) and a Warrant to purchase 1,250 shares of common stock at $4.00 per share. The Debentures have a principal amount equal to 110% of such Purchaser’s subscription amount, convertible at $2.00 per share and maturing one (1) year from the date the subscription amount is accepted by the Company. The Warrants for a number of shares equal to the subscription amount divided by the conversion price with an exercise price of $4.00 per share, exercisable upon issuance and will expire five years from issuance. The Debentures will not be redeemable but contain an automatic conversion feature, which will cause all principal and interest due under the Debenture to automatically convert if our common stock is listed for trading on a national securities exchange, such as NASDAQ or the NYSE. As of JuneSeptember 30, 2025, 2025, a total of 69 Units were sold to accredited investors at a price of $5,500 per Unit totaling $379,717 (total of $345,197 cash was received).

Between June 2023 and September 2024, $3,069,348 in aggregate principal amount of the notes were converted into 371,110 common shares and 1,116.29 shares of Series B Convertible Preferred Stock. Each share of Series B Convertible Preferred Stock converts into 125.63 shares of the Company’s common stock, subject to antidilution adjustments for any stock splits and recapitalizations, and for the issuances of additional shares at an issue price of less than the conversion ratio.

Added

In addition, in August and September 2025, the Company entered into two Notes totaling $232,100 (total of $207,500 cash was received) that provide for a variable conversion price. The Notes provide for a variable conversion rate per share equal to 65% and 75%, respectively, of the lowest trading price for the proceeding 10 trading days prior to a conversion, are due in one year and provide for interest of 7% to 8% per annum. The Company determined that in accordance with ASC 815-15, Embedded Derivatives, it should bifurcate and separately recognize the variable conversion rate at its fair value and at each subsequent measurement date, remeasure its fair value with such changes in fair value recorded in earnings. The Company recognized a total value of $181,362 as a derivative on the grant dates (based on the Binomial valuation model on the date of grant). During the three and nine months ended September 30, 2025 and 2024, the Company did not recognize a remeasurement to fair value as it was deemed immaterial. The issuances of the foregoing securities are exempt from registration pursuant to Section 4(a)(2) of the Securities Act promulgated thereunder as the Sellers are sophisticated investors and familiar with the Company’s operations. No stock purchase warrants were issued as part of the agreement.

We are advancing CardioDialysis™ to treat cardiovascular disease, the leading cause of death globally. CardioDialysis™ aims to reduce the circulating presence of inflammatory molecules that fuel cardiovascular disease progression while simultaneously lowering levels of cholesterol-transporting lipoproteins that contribute to heart attacks, strokes, and other Major Adverse Cardiovascular Events (MACE).

Added

Our Initial Clinical and Commercialization Focus to Treat ESRD Dialysis Patients

Added

Our initial clinical and commercialization focus of CardioDialysisTM is directed toward the treatment of cardiovascular disease in end-stage renal disease (ESRD) patients. According to the U.S. Renal Data System (USRDS), cardiovascular disease is attributed to 67% of ESRD patient deaths and its incidence is 20 times higher in dialysis patients as compared to the general population.

Added

Beyond high mortality rates, we believe cardiovascular disease is a well-defined, yet substantial market opportunity, given an estimated 550,000 ESRD patients receive ~85 million dialysis treatments in the U.S. each year. To optimize potential market penetration within the dialysis industry, CardioDialysis™ can be conveniently integrated with regularly scheduled dialysis treatments.

Added

A Medical Device Precedent to Treat Cardiovascular Disease

Added

CardioDialysis™ targets multiple key therapeutic pathways, including cholesterol-transporting lipoproteins that play a central role in the development and progression of cardiovascular disease.

Added

Lipoprotein Apheresis (LA) is an FDA-approved device precedent that demonstrates blood purification can significantly reduce Major Adverse Cardiovascular Events (MACE) by lowering levels of lipoprotein(a) and low-density lipoprotein cholesterol (LDL-C) in the bloodstream. In a recent review article published by the American Heart Association, Lipoprotein Apheresis was reported to lower the incidence of MACE by 59% to 95% across 11 studies encompassing 1,387 treated patients. In contrast, pharmaceutical statins (Lipitor, Crestor, and Zocor) to reduce LDL-C levels are reported to reduce MACE by 20% to 45%.

Added

However, the clinical adoption of Lipoprotein Apheresis has remained constrained by a limited delivery infrastructure, with fewer than 60 specialized apheresis centers able to provide access to the therapy in the United States.

Added

Opportunity to Leverage the Global Dialysis Machine Infrastructure

Added

CardioDialysis™ is not constrained by delivery infrastructure as it can be deployed on dialysis machines already located in hospitals and clinics around the world. An estimated 150,000 dialysis machines are located in more than 7,500 kidney dialysis clinics in the United States alone. By leveraging this infrastructure, we envision a future possibility to transform current kidney dialysis clinics into Renal and CardioDialysis™ treatment centers.

Added

Potential Value of CardioDialysis™ to the Dialysis Industry

Added

If successfully advanced, we believe CardioDialysis™ could improve and extend the quality of life of ESRD patients who rely on dialysis for survival. Beyond introducing a potential new revenue source to the dialysis industry, CardioDialysis™ may offer a potential pathway to treat cardiovascular disease in the general population, which is the current commercialization focus of Lipoprotein Apheresis.

Added

Extending ESRD patient lives and reducing their hospitalizations may also provide quantifiable value to the dialysis industry. When ESRD patients are hospitalized, dialysis companies lose revenues as in-clinic dialysis treatments are suddenly administered at out-of-network hospitals. Based on average dialysis revenues of $400 per treatment, the U.S. dialysis industry could recoup up to $654 million in lost revenues for each week of reduced ESRD patient hospitalizations. The U.S. dialysis industry could also increase top-line revenues by ~$2.8 billion for each month of extending ESRD patient lives.

Added

Addressing the Unique Cardiovascular Disease Challenges of Dialysis Patients

Added

ESRD patients face unique cardiovascular disease challenges that are not addressed with drug therapies. Once they become dialysis dependent, the median length of ESRD patient survival is typically 3-5 years. Unlike the general population, clinical studies reveal that ESRD patients receive limited if any clinical benefit from LDL-C reducing statins, the leading class of drugs to treat cardiovascular disease. Additionally, circulating levels of cholesterol-transporting lipoprotein(a) are reported to be two to four times higher in ESRD dialysis patients.

Added

Compounding these treatment challenges is an unfortunate reality. Dialysis treatments induce inflammatory responses that further contribute to cardiovascular disease progression. More specifically, circulating levels of endotoxin and inflammatory cytokines are often elevated in response to dialysis treatment.

Added

At present, there are no market-cleared pharmaceutical products to address Lipoprotein(a), endotoxemia, or the broad-spectrum of inflammatory cytokines observed to be elevated in dialysis patients.

Added

In response, we believe CardioDialysis™ could provide a strategy to reduce circulating LDL-C and Lipoprotein(a) levels, which is clinically proven to reduce major adverse cardiovascular events (MACE). Simultaneously, CardioDialysis™ offers to control dialysis-induced spikes of endotoxin and inflammatory cytokines that contribute to cardiovascular disease progression.

Added

The Enrollment of ESRD Dialysis Patients in Clinic Studies

Added

To obtain potential FDA market approval, we need to demonstrate the safety of CardioDialysis™ in a human feasibility (safety) study and then subsequently conduct pivotal studies to demonstrate treatment efficacy of CardioDialysis™.

Added

Pivotal efficacy studies of our previously proposed indications (including sepsis, drug-resistant bacterial infections and life-threatening viruses) would have been limited to enrolling treatment subjects in a hospital intensive care unit (ICU) setting. Enrolling ICU subjects is a daunting challenge that can restrict the clinical advancement of extracorporeal blood purification technologies.

Added

Whereas we plan to advance feasibility and pivotal efficacy studies of CardioDialysis™ in dialysis clinics, which we believe all reduce the challenge and cost of conducting studies. As per our treatment protocol, ESRD subjects will receive CardioDialysis™ during their regularly scheduled dialysis treatments, which is anticipated to further increase the efficiency of conducting clinical studies.

Added

We plan to conduct first-human feasibility studies of CardioDialysis™ in 12-15 ESRD subjects at three dialysis clinic site locations. The protocol of this study has been incorporated into an Investigational Device Exemption (IDE) that we drafted for FDA submission. Based on our decision to advance CardioDialysis™ to address cardiovascular disease, we can now fulfill FDA’s requirement to clearly define the disease condition we intend to treat in our IDE submission.

Sigyn Therapeutics, Inc. (“Sigyn”, the “Company” “we,” “us,” or “our”) develops medical devices to treat cancer and infectious disease disorders. We believe our lineup of therapeutic candidates is among the most expansive in the field of extracorporeal blood purification. To optimize the benefit of drugs to treat cancer, we invented the ImmunePrepTM platform to enhance the performance of immunotherapeutic antibodies; ChemoPrepTM to improve the delivery of chemotherapy; and ChemoPureTM to reduce chemotherapy toxicity. Our lead therapeutic candidate is Sigyn TherapyTM to address infectious disease disorders that are not treatable with drugs. If successfully advanced, our therapies offer to provide strategic value to the pharmaceutical, dialysis, and organ transplant industry.

Infectious Disease Disorders

Removed

To address infectious disease disorders that are not treatable with drugs, we designed Sigyn TherapyTM to extract deadly pathogens and toxins from a patient’s bloodstream, while simultaneously providing a mechanism to dampen down excessive immune responses that are associated with life-threatening infections. Sigyn TherapyTM has been validated to extract viral pathogens, bacterial toxins (including endotoxin), hepatic toxins and inflammatory cytokines from human blood plasma. These expansive capabilities establish Sigyn TherapyTM as a novel strategy to address several unmet needs in global health:

Previous Infectious Disease Industry Achievements

Removed

We have relevant experience in developing blood purification technologies to treat infectious disease disorders. Most members of our team previously worked alongside our CEO while overseeing development of the first medical device to receive FDA “Emergency Use Authorization” approval to treat an infectious viral pathogen (Ebola) and the first to receive two “Breakthrough Device” designation awards from FDA. As a result of these achievements, TIME Magazine named the device to its list of “Top Inventions” and “Top Medical Breakthroughs.”

Removed

Sigyn TherapyTM Human Studies

Removed

First-in-human clinical studies of Sigyn TherapyTM plan to enroll end-stage renal disease (ESRD) subjects with endotoxemia and concurrent inflammation, which are prevalent, yet untreatable conditions that shorten the lives of dialysis patients. Approximately 550,000 individuals suffer from ESRD in the United States. A therapeutic strategy that helped to extend the lives of ESRD patients may have quantifiable value to the dialysis industry, which is dominated by Fresenius Medical Care and DaVita, Inc. in North America. Based on the number of ESRD patients treated in their networks, every month of extended life would equate to approximately $1 billion in added revenues for each company.

Removed

Emerging Opportunity in Xenotransplantation

Removed

Beyond the post-exposure treatment of infectious disease disorders, Sigyn TherapyTM offers a potential preventative strategy to reduce the spread of infection in organ transplantations, including xenotransplantation, an emerging field related to the transplantation of an organ from a donor animal species into a human recipient. The advancement of xenotransplantation is being fueled by a global shortage of transplantable human organs and the recent emergence of gene-editing technologies that have increased the compatibility of porcine-derived (pig) kidneys for human transplantation. In the United States, approximately 90,000 individuals are on the waitlist for a kidney transplant, yet fewer than 30,000 kidney transplants are performed each year.

Removed

To optimize xenotransplantation outcomes, Sigyn TherapyTM is proposed for administration to:

Removed

This use of Sigyn TherapyTM in these applications corresponds with published FDA guidance on the need for strategies to mitigate the risk of a known or unknown pathogen being transmitted from a porcine-derived organ to a human transplant recipient.
