Sernova Receives Orphan Drug and Rare Pediatric Disease Designations for its Hemophilia A Program from FDA

---

Sernova announces research collaboration with Professor Antonia Follenzi, expert in hemophilia A at the University of Piemonte Orientale

LONDON, Ontario; WINDHAM COUNTY, Connecticut – November 27, 2023 – Sernova Corp. (TSX:SVA) (OTCQB:SEOVF) (FSE/XETRA:PSH), a clinical-stage company and leader in cell therapeutics, today announced the U.S. Food and Drug Administration (FDA) has granted both Orphan Drug Designation (ODD) and Rare Pediatric Disease Designation (RPDD) for the company’s Hemophilia A program.

The FDA grants orphan designation, also referred to as orphan status, to therapies intended for the treatment of rare diseases that affect fewer than 200,000 people in the US. This designation provides certain benefits, including tax credits for qualified clinical testing, waiver or partial payment of FDA application fees and seven years of market exclusivity, if approved. Separately, rare pediatric disease designations are granted for rare diseases that primarily affect children under 18 years old with recipients of this designation being awarded a priority review voucher, upon approval. The priority review voucher may be redeemed, transferred, or sold.

“We are pleased with the FDA’s decision to grant these designations for our novel treatment for Hemophilia A, which uses the Cell Pouch™ in combination with cells corrected for the production of Factor VIII,” commented Cynthia Pussinen, Chief Executive Officer of Sernova. “Hemophilia A is a serious, life limiting condition and we are committed to advancing development of the program, with a hope to positively impact patients around the world who are waiting for improved treatments.”

About Sernova’s Hemophilia A Cell Pouch System Program

Sernova’s Hemophilia A program combines the Sernova Cell Pouch™ with a patient’s own cells and will not require the use of immunosuppression medications. This therapy is intended to replace Factor VIII (FVIII) - an essential blood-clotting protein that is deficient or absent in patients with hemophilia A; this is accomplished by correcting the patient’s own Blood Outgrowth Endothelial Cells (BOECs) and subsequently returning them to the patient via the Cell Pouch™. These modified cells function to release FVIII into the bloodstream, restoring the patient’s ability for clotting during periods of bleeding.

Sernova and research partners, through a Horizon 2020 grant which is part of the EU's research and innovation funding program in proof-of-concept work, successfully corrected human blood cells from patients with hemophilia A to produce Factor VIII using a novel first-in-class gene and cell therapy approach where the corrected cells were transplanted into the pre-implanted, vascularized Cell Pouch in a preclinical model of Hemophilia A. The work demonstrated an improvement in blood clotting using the combined technologies (Efficient and safe correction of hemophilia A by lentiviral vector-transduced BOECs in an implantable device; Molecular Therapy: Methods & Clinical Development Vol.23, Dec 2021).

Collaboration with the University of Piemonte Orientale

The company is pleased to announce a collaboration with the University of Piemonte Orientale, Italy under the direction of Antonia Follenzi MD, Ph.D. Professor of Histology and Cell and Gene therapy. Dr. Follenzi is a pioneer of cell and gene therapy approaches to cure Hemophilia A. Her laboratory has expertise in the generation of BOECs from Hemophilic patients and correcting the FVIII gene using Lentiviral vectors.

The purpose of the new collaboration is to optimize the technology using lentiviral vectors to drive the expression of FVIII transgene under the control of novel promoters into BOECs of hemophilia patients to achieve optimal sustained production of FVIII using an optimized cell dose within the Cell Pouch in an animal model of Hemophilia A. The overall goal of the collaboration is to develop a product combination along with pre-clinical results that support advancing into clinical trials in patients with Hemophilia A.

Professor Follenzi stated, “I am pleased to be working with the Sernova team on these advanced technologies for a new and safe treatment of patients with Hemophilia A using a gene and cell therapy approach within the Cell Pouch. Our goal is to advance these new technologies to further maximize the release of FVIII into the bloodstream and to extend the duration of that release for a sufficient duration of time to eliminate the need for weekly infusions of FVIII and to significantly improve the lives of people with Hemophilia A.”

BENEFITS OF ODD AND RPDD

Combined benefits of these designations include exclusive marketing rights for a seven-year period, after marketing approval, a 25% federal tax credit for clinical research expenses incurred in the US which is applicable for up to 20 years, waiver of Prescription Drug User Fee Act (PDUFA) fees for orphan drugs (currently worth >US$3 million), ability to qualify to compete for research grants from the Office of Orphan Products Development (OOPD) to support clinical studies for the orphan indication, and eligibility to receive regulatory assistance and guidance from FDA to design the development plan.

Furthermore, once the therapy is approved for marketing, it cannot be copied and sold in the US for 7 years regardless of patent life and the sponsor will be granted a Priority Voucher which can be used to receive approximately 4 months reduction time of the standard FDA review period or sold.

ABOUT HEMOPHILIA A

Hemophilia encompasses a group of inherited disorders that alter blood coagulation. Classical hemophilia, also known as hemophilia A, is a hereditary hemorrhagic disorder resulting from a congenital deficit of FVIII that manifests as protracted and excessive bleeding either spontaneously or secondary to trauma. 1 Hemophilia A is the most common form of Hemophilia and is a genetic disorder caused by missing or defective FVIII, a blood clotting protein. Severe Hemophilia A occurs in about 60% of cases where the deficiency of FVIII is less than 1% of normal blood concentration. While it is passed down from parents to children, about 1/3 of cases are caused by a spontaneous change in the gene.

According to the US Centers for Disease Control and Prevention, Hemophilia A occurs in about 1 in 5,000 births. Prolonged bleeding, in areas such as the brain, of a person with Hemophilia A, can be fatal. Prolonged bleeding in joints can cause inflammatory responses and permanent joint damage. Approximately 20,000 people in the United States, 2,500 in Canada and 10,000 in Europe have moderate to severe forms of Hemophilia A. Though there is no cure for the disease, Hemophilia A can be controlled with regular infusions of recombinant clotting FVIII. Treatment costs per patient are as high as US $200,000 or more each year, with an aggregate therapeutic cost of over US$ 10 billion per year.

Sernova Announces New Advancements of Conformal Coating Technology in Combination with the Cell Pouch System™ at the 2023 IPITA-IXA-CTRMS Joint Congress

---

LONDON, Ontario; WINDHAM COUNTY, Connecticut – October 30, 2023 – Sernova Corp. (TSX:SVA) (OTCQB:SEOVF) (FSE/XETRA:PSH), a clinical-stage company and leader in cell therapeutics, today announced an update on its conformal coating immune protection technology program, that is used in combination with the Cell Pouch™.

The goal of the program is to eliminate the need for chronic immunosuppression medications, currently used in islet cell transplantation for type 1 diabetes (T1D) treatment.

The update was presented by Dr. Alice Tomei, of the University of Miami, at the International Pancreas and Islet Transplant Association (IPITA)-International Xenotransplantation Association (IXA)-Cell Transplant and Regenerative Medicine Society (CTRMS) Joint Congress, taking place from October 26-29 in San Diego, California.

The presentation showcased positive advancement in the refinement of the coating composition and process, outcomes of preclinical studies with the Cell Pouch as well as rationale and historical development of the technology.

The following summarizes key advancements presented: • The final conformal coating composition exhibits significantly improved cell compatibility and overall biocompatibility, representing evolution across years of process development work and preclinical testing. • Coating process enhancements resulted in a 500% increase in conformal coating production capacity (number of starting islets to be coated) and an 89% overall islet encapsulation yield (ratio of conformal coated islets to initial islets). These enhancements have a direct positive impact on the in vitro and in vivo efficacy of the coated islets. • The final conformal coated product was purified using a process to contain 98% conformal coated islets and only 2% empty capsules. This enables an increase in the number of functional coated islets that are transplanted within the Cell Pouch chambers and minimization of graft volume. • Using these composition and process development improvements, the coated islets were tested, in combination with the Cell Pouch, in a syngeneic gold standard animal model of T1D to assess the safety and efficacy of the combined product. o Biocompatibility of the coated islets within the Cell Pouch was confirmed histologically demonstrating healthy islets within the vascularized tissue matrix; o Importantly, normal physiological transfer of glucose-stimulated insulin from the conformal coated islets within the Cell Pouch was confirmed; o Diabetic animals that received conformal coated islets within the Cell Pouch exhibited controlled blood glucose to non-diabetic levels - which reversed upon removal of the Cell Pouch - proving function of the conformal coated islets. • A series of pilot studies using conformal coated islets, in combination with the Cell Pouch, in an allogeneic rat model of T1D established the optimal conditions to achieve diabetes reversal. These conditions, which are being used in confirmatory allogeneic studies in additional upcoming preclinical work, included: o Drug kinetic studies which identified the optimal dose and frequency of a single selective immune response agent to be used in combination with conformal coated islets; o Islet dose-dependent glucose control was demonstrated using conformal coated islets in the Cell Pouch with the selective immune response agent.

• The release criteria essential for clinical manufacturing have been developed, including coating conformality, completeness, stiffness, thickness, and selective permeability. Using these criteria, the conformal coating material showed long term mechanical stability, durability and selective permeability to insulin and glucose molecules but not to antibodies or inflammatory cells. These are key requirements for long-term function of the conformal coating technology in vivo.

• Significant progress was achieved in manufacturing of the coating scale up equipment. Prototype devices are manufactured, and testing is in progress. Final system design will provide fully automated, GMP- compliant coating applied to transplantable coated islets. The system function will involve conformal coating, washing, counting and production monitoring.

“We have made significant advancements in the evolution of the conformal coating technology in our collaboration with Sernova and are confident we have the final formulation. I look forward to our continuing studies and presenting more results,” said Dr. Alice Tomei, Miami Engineering Career Development Associate Professor of Biomedical Engineering at the University of Miami and director of the Islet Immunoengineering Lab at the Miller School of Medicine Diabetes Research Institute.

“We understand that eliminating the standard immune suppression regimen is key to Sernova delivering a ‘functional cure’ for all T1D patients,” said Cynthia Pussinen, Chief Executive Officer at Sernova. “Our goal is to continue to drive this technology ahead and ultimately bring a local immune-protected cell product into the clinic combined with the Sernova Cell Pouch and iPSC islet-like clusters.”

RELEVANT PRESENTATION DETAILS

Title: Transplantation of Conformal Coated Islets in a Pre-Vascularized Cell Pouch™ Device for Beta Cell Replacement in Diabetic Rats Session: Islet Transplantation: Engineering the Islet Site Session Date: Friday, October 27, 2023

ABOUT THE CONFORMAL COATING TECHNOLOGY

The conformal coating technology is a proprietary, mechanically stable, thin, biocompatible, and cross-linked polymer hydrogel that coats the outside of each individual islet housed within the Cell Pouch. The conformal coating technology offers selective permeability, with immuno-protective capability, while not interfering with the kinetics of insulin and glucose release. Importantly, the conformal coating configuration also allows for the physiological transfer of oxygen and nutrients needed for islet survival and long-term function within the pre- vascularized Cell Pouch.

Sernova Announces Positive Ongoing Interim Phase 1/2 Clinical Data for the Cell Pouch System™ for Type 1 Diabetes Trial at the 2023 IPITA, IXA, and CTRMS Joint Congress

---

• All six patients in the first cohort (Cohort A) were successfully implanted with the 8-channel Cell Pouch System with post-transplant follow-up periods ranging from 6 months to 3.5 years; • 5 of 6 patients in Cohort A discontinued insulin therapy (insulin independent) following islet transplantation into the Cell Pouch and modest islet top-up via portal vein. All 6 patients achieved HbA1c values in the non-diabetic range (<6.5%); • In Cohort B, the first 6 of 7 planned patients have received the higher capacity 10-channel Cell Pouch and 5 patients have received a first islet transplant; • Stable fasting and stimulated serum C-peptide levels were observed following a single islet transplant into the 10-channel Cell Pouch in the first assessable Cohort B patient who subsequently achieved insulin independence with a modest portal vein top up.

LONDON, Ontario; WINDHAM COUNTY, Connecticut – October 27, 2023 – Sernova Corp. (TSX:SVA) (OTCQB:SEOVF) (FSE/XETRA:PSH), a clinical-stage company and leader in cell therapeutics, today presented interim positive results from its ongoing Phase 1/2 clinical trial investigating islet allotransplantation into pre- vascularized Sernova Cell Pouch™ during an oral presentation at the 2023 IPITA, IXA, and CTRMS Joint Congress in San Diego, California.

Enrollment in Cohort A, which utilizes the 8-channel Cell Pouch, is complete with post-transplant data available for periods of follow-up ranging from 6 months to 3.5 years. Enrollment in Cohort B, which utilizes the higher capacity Cell Pouch and a revised and better-tolerated immunosuppressive regimen, began in November 2022 and 6 of the 7 planned patients have now been successfully implanted.

The primary objective of the study is to investigate the safety and tolerability of islet transplantation into Cell Pouch in patients with T1D, impaired hypoglycemia awareness, and a history of severe hypoglycemic episodes. Secondary study objectives include establishment of islet release criteria predictive of outcomes from islet transplant into the Cell Pouch and optimal dose and concentration ranges for purified islets transplanted into the Cell Pouch.

Interim results from Cohort A demonstrated successful implantations of the 8-channel Cell Pouch in the 6 treated patients that were well tolerated with no seromas and no unexpected AEs (adverse events), chronic pain or discomfort. Data showed histological evidence of surviving and functional islets and positive fasting and stimulated serum C-peptide (a measure of islet insulin secretion) in patients who maintained optimal immunosuppression. All 6 patients eventually received supplemental, marginal-dose islet infusions via the portal vein with the first 5 having achieved sustained insulin independence. All 6 Cohort A patients achieved HbA1c values in the non-diabetic range (<6.5%) with persistent serum fasting and stimulated C-peptide levels for current durations out to 3.5 years.

In Cohort B, 6 of the planned 7 patients have been implanted with the higher capacity 10-channel Cell Pouch, without complications. Among the 6 patients that have been implanted, 5 have completed at least one of the two protocol-defined islet transplants to Cell Pouch.

The first assessable patient in Cohort B following the first Cell Pouch islet transplant showed persistent fasting and stimulated serum C-peptide, with stable BETA-2 scores (a measure of islet graft function) that continued at Day 180 following their first islet transplant to Cell Pouch. The same patient showed modest but favorable improvements in HbA1c from 7.5% at baseline to 6.9% also at Day 180.

The day following the second islet transplant to Cell Pouch, results from a sample of the islets taken from the donor pancreas on the day of transplant came back positive for the yeast, Candida albicans. Out of an abundance of caution, Cell Pouches containing the contaminated islets were immediately removed. The Cell Pouches that were previously transplanted with the first dose of uncontaminated, healthy islets were not removed and remained in place, continuing to function. Explantation of the Cell Pouches containing contaminated islets was completed without complications and the patient fully recovered without any wound or systemic blood infection, demonstrating the designed retrievability of the transplanted Cell Pouch. Following recovery, this patient received a modest intraportal islet transplant and remains insulin independent. The revised immunosuppression protocol, used in Cohort B, continues to demonstrate favorable protection for the islet grafts with no donor islet rejection or donor specific antibodies observed under the new regimen.

“I am pleased with the overall patient outcomes and learnings from the first trial cohort. We have applied those learnings to the second patient cohort along with the introduction of the higher capacity 10-channel Cell Pouch.” commented Dr. Piotr Witkowski, Director of the Pancreatic and Islet Transplant Program at The University of Chicago, and principal investigator for the Sernova trial. “I am encouraged by the positive safety profile observed with Cell Pouch implants longer than 4 years, and early patient outcomes with the enhanced 10-channel device that we are using in the second cohort. Enrollment of the second cohort is nearly complete, and I look forward to reporting further results.”

“We are very encouraged by the results and our learnings from our trial to date.” said Cynthia Pussinen, Chief Executive Officer at Sernova. “Having recently advanced the trial into Cohort B, using our higher capacity 10- channel Cell Pouch, we are already seeing positive signals for both safety and efficacy. We look forward to sharing the next trial update, in the coming months.”

These results were presented by Piotr Witkowski, Professor of Surgery at the University of Chicago at the International Pancreas and Islet Transplant Association (IPITA), the International Xenotransplantation Association (IXA), and the Cell Transplant and Regenerative Medicine Society (CTRMS) Joint Congress, taking place from October 26 – 29 in San Diego, CA as an oral presentation entitled “Islet allotransplantation into pre- vascularized Sernova Cell Pouch - Lessons learned from the first patient cohort” (Abstract #105, Session: “Islet Transplantation: Engineering the Islet Site Session,” Thursday, October 26, 2023 2:45 p.m. to 3:45 p.m. PT)

Sernova Presents Compelling New Data on the Cell Pouch System™ as a Promising Treatment for Post-Operative Hypothyroidism at the 2023 American Thyroid Association Annual Meeting

---

Proof-of-concept data supports the clinical evaluation of the Cell Pouch System as a potential treatment for post-operative hypothyroidism

LONDON, Ontario; WINDHAM COUNTY, Connecticut – September 29, 2023 – Sernova Corp. (TSX:SVA) (OTCQB:SEOVF) (FSE/XETRA:PSH), a clinical-stage company and leader in cell therapeutics, today announced new preclinical data for its novel cell therapy platform, the Cell Pouch System, as a potential treatment for post-operative hypothyroidism at the 2023 American Thyroid Association (ATA) Annual Meeting being held in Washington, D.C., from September 27 to October 1, 2023.

Key insights from the poster:

• After total thyroidectomy, re-implantation of thyroid tissue into the pre-vascularized Cell Pouch™ resulted in the restoration of the two main thyroid hormones, i.e., free thyroxine (FT4) and triiodothyronine (T3), to the baseline levels.

• Thyroid stimulating hormone (TSH) levels had a significant peak immediately after thyroidectomy, with a gradual decline observed starting five weeks after the re-implantation of thyroid glands. This pattern underscores the re-establishment of the intrinsic thyroid feedback loop's impact.

• Newly reported radio-isotope uptake imaging and histology assessments confirmed the presence of healthy and functional thyroid tissues within the Cell Pouch six months following re-implantation.

“Currently, thyroidectomy patients are bound to life-long thyroid hormone replacement therapy. A significant subset of those patients grapple with persistent symptoms of thyroid dysfunction including weight gain, fatigue, depression, memory and cognitive impairment, negatively impacting their quality of life,” said Cynthia Pussinen, Chief Executive Officer at Sernova. “With Sernova’s Cell Pouch System, we aim to improve quality of life with a treatment for post-operative hypothyroidism. These new data replicate a human clinical scenario in which thyroid tissue is reimplanted into the patient, via the Cell Pouch, leading to the restoration of normal thyroid function. Sernova is assessing the commercial opportunity and pathways for accelerated development of the thyroid program.”

Approximately 150,000 thyroidectomies are performed annually in the U.S. alone, representing a significant market opportunity*. Sernova’s potential first-generation product would utilize healthy tissue from the patient’s own gland removed during thyroidectomy for benign disease. This therapeutic approach would negate the need for immune suppression medication. A second-generation stem cell-derived technology could potentially be used to treat the broader population with hypothyroid disease.

(*Sun, G. H., DeMonner, S., & Davis, M. M. (2013). Epidemiological and economic trends in inpatient and outpatient thyroidectomy in the United States, 1996–2006. Thyroid, 23(6), 727-733.)

Title: Auto-Transplantation of Rat Thyroid into a Pre-Vascularized Retrievable Cell Pouch™ Device for the Treatment of Post-Operative Hypothyroidism Presenter: Dr. Arash Memarnejadian, Senior Research Scientist, Sernova Corp. Date and Time: September 29 from 9:50 a.m. to 12:40 p.m. Eastern Time Poster #: 323

ABOUT SERNOVA CORP. AND THE CELL POUCH SYSTEM PLATFORM FOR CELL THERAPY Sernova Corp. is a clinical-stage biotechnology company that is developing therapeutic cell technologies for chronic diseases, including insulin-dependent diabetes, thyroid disease, and blood disorders that include hemophilia A. Sernova is currently focused on developing a ‘functional cure’ for insulin-dependent diabetes with its lead asset, the Cell Pouch System, a novel implantable and scalable medical device with immune protected therapeutic cells. On implantation, The Cell Pouch forms a natural vascularized tissue environment in the body for long-term survival and function of therapeutic cells that release essential factors that are absent or deficient in the bodies of patients with certain chronic diseases. Sernova’s Cell Pouch System has demonstrated its potential to be a ‘functional cure’ for people with T1D in an ongoing Phase 1/2 clinical study at the University of Chicago, with Cell Pouches implanted for periods of more than four years and counting.

Sernova is also advancing a proprietary technology in collaboration with the University of Miami to shield therapeutic cells from immune system attack with the goal to eliminate the need for chronic, systemic immunosuppression. In May 2022, Sernova and Evotec entered into a global strategic partnership to develop an implantable off-the-shelf iPSC (induced pluripotent stem cells) based islet replacement therapy. This partnership provides Sernova a potentially unlimited supply of insulin-producing cells to treat millions of patients with insulin-dependent diabetes (type 1 and type 2). Sernova continues to progress two additional development programs that utilize its Cell Pouch System: a cell therapy for hypothyroid disease resulting from thyroid gland removal and an ex vivo lentiviral Factor VIII gene therapy for hemophilia A.

Sernova Provides Development Update on Proprietary Cellular Conformal Coating Technology in Combination with Cell Pouch Device

---

Dr. Alice Tomei of the University of Miami, Miller School of Medicine, to present updates in podium presentation at the 2023 IPITA-IXA-CTRMS Joint Congress being held in San Diego from October 26-29

LONDON, Ontario; WINDHAM COUNTY, Connecticut – September 7, 2023 – Sernova Corp. (TSX:SVA) (OTCQB:SEOVF) (FSE/XETRA:PSH), a clinical-stage company and leader in cell therapeutics, today provided a development update on its exclusively licensed, proprietary conformal coating immune protection technology, being advanced in combination with the Cell Pouch™ through a collaboration with Dr. Alice Tomei at the University of Miami, Miller School of Medicine. The goal of the technology is to eliminate the need for long- term use of conventional immunosuppressive medications currently required to prevent graft rejection with Sernova’s flagship cell therapy program for treatment of type 1 diabetes (T1D).

“One of the biggest challenges in bringing a ‘functional cure’ to people living with T1D is preventing therapeutic cell transplantation from eliciting an immune response without the need for conventional life-long immunosuppressive agents,” said Dr. Philip Toleikis, Chief Technology Officer of Sernova Corp. “Our conformal coating technology closely surrounds insulin-producing islets without altering the genetic makeup or function, offering potential protection from the human immune system while maintaining normal cell function. We are encouraged by both our ongoing preclinical results, and our continued progress with manufacturing scale-up of conformally coated islets, which is a key hurdle prior to initiation of clinical studies.”

The conformal coating technology has been developed in partnership with Dr. Alice Tomei, Miami Engineering Career Development Associate Professor of Biomedical Engineering at the University of Miami and director of the Islet Immunoengineering Lab at the Miller School of Medicine Diabetes Research Institute. Dr. Tomei will provide a detailed update of the technology in a podium presentation at the 2023 IPITA-IXA-CTRMS Joint Congress being held in San Diego from October 26-29. Presentation details will be shared in October 2023.

Dr. Tomei added, “I am pleased with the technical advancements we have made in collaboration with the Sernova scientific team. We have achieved success in pre-clinical safety and efficacy studies demonstrating the optimal conditions for conformally coated islets within the Cell Pouch. We have also made significant progress in developing release criteria which are essential for the clinical manufacturing process. Furthermore, along with Sernova, we have optimized the manufacturing process and are currently scaling up the GMP production of the conformally coated islets. These elements are critical to advancing the conformal coating technology into the clinic for the potential treatment of all patients with T1D. I look forward to sharing more on our progress at the 2023 IPITA-IXA-CTRMS Joint Congress in San Diego.”

Pre-clinical studies conducted at the University of Miami in collaboration with Sernova demonstrated that conformally coated islets transplanted into the pre-vascularized Cell Pouch achieved normal blood glucose control and reversed the effects of T1D in a syngeneic rat model of T1D. Conformally coated islets show normal responsiveness to glucose and fully regulated insulin production when transplanted in the Cell Pouch. Treated animals ultimately achieved full insulin independence (return to normal glucose levels).

In optimization studies in T1D animal models transplanted with conformally coated allogeneic islets in an implanted Cell Pouch, subjects treated with a single selective immune response agent achieved sustained, normalized blood glucose levels during the study period. These findings support our approach and the potential to eliminate the need for the immunosuppressive cocktails that are typically used for islet transplant patients and are frequently associated with toxic side effects.

As prerequisites for clinical testing in humans, characterization assays have been identified to develop and validate product release criteria for conformal coating. Long-term in vitro stability and durability studies have been successfully completed and release testing is routinely conducted for the finished coated islet product to ensure quality, safety, and efficacy potential, prior to the transplantation of conformally coated islets into Cell Pouch. Sernova is also undertaking a standard array of biocompatibility studies and is completing an allogeneic optimization study using conformally coated islets in the Cell Pouch with the addition of a selective immune response agent which has proven effective in the ongoing Phase 1/2 clinical trial of the Cell Pouch System™ in T1D at the University of Chicago. A single agent provided intermittently with the conformal coating technology would be a significant advancement in the field of cellular immune protection.

Additionally, through a design and manufacturing partner, Sernova is developing a bench-top, scalable, fully automated, and GMP-compatible cell coating system. The clinical-scaled system is designed for installation in GMP cell manufacturing facilities that produce coated islets for clinical trials.

ABOUT THE CONFORMAL COATING TECHNOLOGY The conformal coating technology is a proprietary, mechanically stable, thin, biocompatible, and cross-linked polymer hydrogel that coats the outside of each individual islet housed within the Cell Pouch. The conformal coating technology offers selective permeability, with immuno-protective capability, while not interfering with the kinetics of insulin and glucose release. Importantly, the conformal coating configuration also allows for the physiological transfer of oxygen and nutrients needed for islet survival and long-term function within the pre- vascularized Cell Pouch.
