Sernova Announces Advancements with its Novel Cell Pouch SystemTM to Preserve Thyroid Function Following Total Thyroidectomy

- Preclinical proof of concept study demonstrates that thyroid auto-transplantation into the Cell Pouch can restore thyroid hormone production following removal of the thyroid gland - Sernova has engaged with regulatory authorities towards initiating clinical development of a prospective therapy for hypothyroidism

LONDON, Ontario – January 30, 2023 – Sernova Corp. (TSX:SVA) (OTCQB:SEOVF) (FSE/XETRA:PSH), a clinical-stage company and leader in cell therapeutics, today announced advancements in its thyroid cell therapy program – one of three cell therapy development programs utilizing the Company’s proprietary Cell Pouch System™. In a preclinical proof of concept study, the Company demonstrated that auto-transplantation of thyroid tissue into the Cell Pouch can compensate for removal of the thyroid gland (total thyroidectomy), restoring normal thyroid hormone levels in an animal model.

The thyroid is a vital hormone-producing gland that is critical for metabolism and regulation of body functions.1 Loss of thyroid function occurs following surgical removal of the gland and is associated with memory impairment, depression, intolerance to cold, chronic fatigue, constipation, weight gain and lethargy.2 It is estimated that more than 150,000 patients in the US undergo thyroidectomies annually3, and subsequently require lifelong thyroid hormone replacement therapy.

Despite some benefits, patients on thyroid replacement medications often experience significant impairment in psychological well-being.4 The primary goal of Sernova’s thyroid program is to restore normal thyroid function without life-long medication, and avoid the burden of repeated laboratory testing in patients who have undergone thyroid surgery.

Data from Sernova’s preclinical program demonstrates that total thyroidectomy with auto-transplantation into the Cell Pouch allows for reestablishment of production of triiodothyronine (T3) and thyroxine (T4).

The study was conducted in a pre-clinical animal model whereby the Cell Pouch was pre-implanted for several weeks prior to each subject undergoing total thyroidectomy. The thyroid gland of each Treatment Group subject was removed, prepared with minimal manipulation, and transplanted into the pre-implanted Cell Pouch. Thyroid hormones were monitored over several months with weekly measurements of circulating thyroid hormones (T3, T4). Following thyroidectomy in the Treatment Group, the T3 and T4 levels fell initially but subsequently recovered to normal or near-normal levels following thyroid transplant into the Cell Pouch. Control Group subjects received the Cell Pouch implant and underwent total thyroidectomy but did not receive a thyroid transplant. In the Control Group, post-thyroidectomy T3 and T4 rapidly decreased and remained below baseline concentrations throughout the experiment.

“Along with previously published preclinical data that reported survival and function of human thyroid tissue transplanted into the Cell Pouch5, this preclinical study also supports the viability of Sernova’s Cell Pouch System approach and represents an important step towards establishing an entirely new treatment option for post-thyroidectomy hypothyroidism,” commented Dr. Sam Wiseman, BSc, MD, FRCSC, FACS.

“These findings demonstrate a further therapeutic application of Sernova’s Cell Pouch System,” said Dr. Philip Toleikis, President and Chief Executive Officer of Sernova. “In addition to type 1 diabetes [and hemophilia], this study shows the potential to treat the significant number of patients undergoing removal of their thyroid glands each year. We have already begun to interact with regulatory authorities towards initiating clinical trials with this novel therapy.”

Sernova intends to present data from the Company’s thyroid development program at a scientific conference later this year.

ABOUT SERNOVA’S CELL THERAPY THYROID DISEASE PROGRAM

Sernova is utilizing its Cell Pouch System platform as a potential treatment for hypothyroid disease. Our approach is to transplant a patient’s own healthy thyroid tissue following thyroidectomy into the pre-implanted vascularized Cell Pouch to preserve the normal thyroid function and reduce or eliminate the need for lifelong daily thyroid replacement therapy. Sernova plans to conduct clinical assessments of the Cell Pouch with transplanted thyroid tissue in patients suffering from post-surgical hypothyroidism with the aim of preserving thyroid function and improving patient quality of life.

Thyroidectomy is commonly performed for cancer diagnosis or treatment and for treatment of benign (non- cancerous) disease that includes goiter and hyperthyroidism. It is estimated that about 150,000 thyroidectomies are performed in the US yearly. Patients undergoing total thyroidectomy, and many patients undergoing partial thyroidectomy, require life-long thyroid hormone medication. Post-surgical thyroid hormone replacement therapy, if monitored carefully, can be effective; however, patients often suffer from deleterious side-effects including weight gain, depression, headaches, and cardiovascular disease, with resultant negative impact on quality of life, and significant costs to the healthcare system. The development of new therapeutic strategies to overcome hypothyroidism remains an important unmet medical need.

Sernova Announces First Two Patients Implanted with Cell Pouch™ in the Second Cohort of its US Phase 1/2 Clinical Trial for Type 1 Diabetes

- Company’s recent recruitment strategy change has resulted in an unprecedented level of inquiries regarding potential study participation - Transplantation of islets into the enhanced 10-channel Cell Pouch is anticipated in early 2023 - Company continues to anticipate first interim safety/efficacy data from second cohort in 2023

LONDON, Ontario – November 17, 2022 – Sernova Corp. (TSX:SVA) (OTCQB:SEOVF) (FSE/XETRA:PSH), a clinical-stage company and leader in cell therapeutics, announced today that the first two patients in the second cohort of its active U.S. Phase 1/2 type 1 diabetes (T1D) clinical trial have been implanted with its 10- channel Cell Pouch, which provides >50% more capacity relative to the Cell Pouches used for the first cohort. The transition to this new 10-channel Cell Pouch under the revised protocol enables optimized dosing and shorter efficacy evaluation periods to ultimately decrease time to key efficacy endpoints. These endpoints include survival of transplanted islet cells, reduction of severe hypoglycemic episodes, changes in HbA1c, increased C-peptide production, and reduction in insulin requirements.

Sernova has engaged a clinical trial recruitment partner with extensive experience and success in accelerating T1D clinical trial patient enrollment. The second cohort of the study is intended to enroll up to seven patients with insulin dependent T1D who also suffer from severe hypoglycemic episodes and hypoglycemia unawareness. The Company anticipates reporting interim data in 2023. Results from the combined cohorts will inform the design of Sernova’s anticipated Phase 3 T1D pivotal study.

“Our drive to liberate individuals suffering with type 1 diabetes from the burden of daily insulin injections has been strengthened by the safety and efficacy observations in the first cohort of patients in our Phase 1/2 study, and we are pleased to have commenced the treatment phase for the second cohort,” said Dr. Philip Toleikis, President and Chief Executive Officer of Sernova. “We believe the new 10-channel Cell Pouch configuration provides for optimal dosing of islets towards achievement of a potential ‘functional cure’. We look forward to reporting interim data from the second cohort in 2023. Planning and preparations are underway for the pivotal trial program, while we advance our iPSC-derived islet program into the clinic in collaboration with Evotec.”

ABOUT THE US PHASE 1/2 SECOND STUDY COHORT

The US Phase 1/2 study (NCT03513939) is an open-label single-arm trial to assess the safety, tolerability, and efficacy of Sernova’s Cell Pouch System™ for clinical transplantation of human donor islets in patients with T1D. Six patients were transplanted in the first cohort utilizing the 8-channel Cell Pouch System and interim data have been previously reported by Dr. Piotr Witkowski and his colleagues. With the expansion into the second cohort utilizing the 10-channel Cell Pouch System, patient eligibility criteria remain unchanged and includes those aged 18-65 with T1D who suffer from both hypoglycemic unawareness and severe hypoglycemic episodes, and who are eligible for donor islet transplantation. Eligible trial patients have had at least one episode of severe hypoglycemia in the previous 12 months and an absence of stimulated C-peptide (a marker of insulin production by the body) in response to a mixed meal tolerance test.

Islets are transplanted into the Cell Pouch approximately six weeks after Cell Pouch implantation to allow development of fully vascularized native tissue chambers and achieve a stable immunosuppressant regimen. At 90 days post-islet transplant, safety and efficacy are assessed prior to initiating a second transplant of islets. At 90 days following each patient’s second islet transplant to Cell Pouch, safety and efficacy endpoints are evaluated again. Trial patients who remain dependent on insulin for at least 6 months following the second islet transplant to Cell Pouch may be eligible for a third supplemental islet transplant via the portal vein.

Patients who elect to retain their implants will be followed for up to 3 years after the final islet transplant into the Cell Pouch. Multiple transplanted patients from the first cohort have implant durations of more than 3 years and none have elected to have their Cell Pouch implants removed. The primary objective of the Phase 1/2 study is safety and tolerability. Secondary objectives include the following efficacy endpoints: production of C-peptide, insulin use, HbA1c and frequency of hypoglycemic events.

ABOUT SERNOVA CORP. AND THE CELL POUCH SYSTEM™ PLATFORM FOR CELL THERAPY Sernova Corp. is a clinical-stage biotechnology company that is developing regenerative cell therapeutic technologies for chronic diseases, including insulin-dependent diabetes, thyroid disease, and blood disorders including 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 necessary proteins or factors missing from the body to treat chronic diseases. Sernova’s Cell Pouch System has already shown it can potentially provide a ‘functional cure’ to people with type 1 diabetes in an ongoing Phase 1/2 clinical study at the University of Chicago. Sernova is also advancing a proprietary technology in collaboration with the University of Miami to cloak the therapeutic cells from the immune system attack with the goal to eliminate the need for chronic immunosuppressives. In May 2022, Sernova and Evotec entered into a global strategic partnership to develop an implantable off-the-shelf iPSC-based (induced pluripotent stem cells) beta cell 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 is also in development of two additional programs that utilize its Cell Pouch System – an implantable cell therapy for benign thyroid disease resulting from thyroid gland removal and an ex-vivo lentiviral Factor VIII gene therapy for hemophilia A.

Sernova Receives Authorization to Enroll Second Patient Cohort of Phase 1/2 Trial with Cell Pouch System™ for Type 1 Diabetes

Sernova plans to begin enrollment of second cohort in the coming weeks and implant multiple patients with the enhanced capacity 10-channel Cell Pouch before the end of 2022

Positive interim results from patients in the first cohort informed the islet dose and density threshold optimizations for the second cohort

Expedited enrollment is anticipated with Sernova’s engagement of an experienced clinical trial patient recruitment agency and the Company expects to report interim data in 2023

Results from the combined cohorts will help guide the design of Sernova’s pivotal study, which would support an anticipated BLA submission to the US FDA and accelerate our iPSC stem cells into the clinic

LONDON, Ontario – November 3, 2022 – Sernova Corp. (TSX:SVA) (OTCQB:SEOVF) (FSE/XETRA:PSH), a clinical-stage company and leader in cell therapeutics, is pleased to announce, in conjunction with the advancement of its ongoing Phase 1/2 clinical trial of the Sernova Cell Pouch System™ for patients with type 1 diabetes (T1D) who suffer from hypoglycemia unawareness (the “T1D Study”), the approval of a protocol amendment by the University of Chicago Institutional Review Board (IRB) and no objections from FDA, allowing the Company to proceed with a strategically optimized protocol reducing the time required for patient treatment while accelerating potential secondary endpoint efficacy achievement with more optimal dosing.

Following promising interim results from the first six patients of Sernova’s active T1D Study, the protocol amendment enables the testing of a small second cohort of up to seven patients, to evaluate the Company’s optimized 10-channel Cell Pouch™, which provides 50% more islet capacity compared to the 8-channel Cell Pouch used to date for the T1D Study. Study data from the first six patients formed the basis for the amended optimized treatment plan for the additional new cohort of patients. Results from the combined cohorts will help guide the design of Sernova’s pivotal study, supporting an anticipated BLA submission to the US FDA.

With the protocol amendment, enrollment of the first cohort of patients has concluded and patient enrollment for the new second cohort will begin. The first three patients of the first cohort with completed islet transplants have achieved insulin independence and the remaining three are progressing towards completion of the treatment regimen. Data from these first patients has enabled Sernova to determine dose thresholds and islet concentrations intended to optimize endogenous insulin production in treated patients. Furthermore, safety observations to date support reducing the time between Cell Pouch islet transplants from 180 to 90 days, which substantially reduces the overall treatment period in the amended protocol update. To expedite rapid enrollment of the second cohort, Sernova has engaged a clinical trial patient recruitment partner with extensive experience and success in accelerating T1D clinical trial patient enrollment.

“Sernova is committed to developing a potential ‘functional cure’ with the goal of freeing patients from the life- limiting burdens of T1D and dramatically enhancing their quality of life,” said Dr. Philip Toleikis, President and Chief Executive Officer. “We are pleased with the positive interim results demonstrating that the Cell Pouch System is well tolerated, reduces or eliminates the frequency of severe hypoglycemic events and continues to contribute to durable insulin independence among patients. Based on our now expanded recruitment activities and efforts, we anticipate implanting multiple patients before the end of 2022. The results from these additional patients will directly contribute to our pivotal T1D trial design and help accelerate entry into the clinic with our iPSC stem cell derived islet technology in conjunction with our Evotec partnership that is progressing ahead of our expectations.”

ABOUT PHASE 1/2 STUDY SECOND COHORT

The Phase 1/2 study (NCT03513939) is an open-label single-arm trial to assess the safety, tolerability, and efficacy of Sernova’s Cell Pouch System for clinical transplantation of human donor islets in patients with T1D. Six patients were transplanted in the first cohort utilizing the 8-channel Cell Pouch System and interim data have been previously reported by Dr. Piotr Witkowski and his colleagues. With the expansion into the second cohort utilizing the 10-channel Cell Pouch System, patient eligibility criteria remain unchanged and includes those aged 18-65 with T1D who suffer from both hypoglycemic unawareness and severe hypoglycemic episodes, and who are eligible for donor islet transplantation. Eligible trial patients have had at least one episode of severe hypoglycemia in the previous 12 months and an absence of stimulated C-peptide (a marker of insulin production by the body) in response to a mixed meal tolerance test.

Islets are transplanted into the Cell Pouch approximately six weeks after Cell Pouch implantation to allow development of fully vascularized native tissue chambers and achieve a stable immunosuppressant regimen. At 90 days post-islet transplant, safety and efficacy are assessed prior to initiating a second transplant of islets. At 90 days following each patient’s second islet transplant to Cell Pouch, safety and efficacy endpoints are evaluated again. Trial patients who remain dependent on insulin for at least 6 months following the second islet transplant to Cell Pouch may be eligible for a third supplemental islet transplant via the portal vein.

Patients who elect to retain their implants will be followed for up to 3 years after the final islet transplant to Cell Pouch. Multiple transplanted patients from the first cohort have implant durations of more than 3 years and none have elected to have their Cell Pouch implants removed.

The primary objective of the Phase 1/2 study is safety and tolerability. Secondary objectives include the following efficacy endpoints: production of C-peptide, insulin use, HbA1c, and frequency of hypoglycemic events.
