OVERALL CLINICAL OBSERVATIONS FOR HAV • The HAV has been in clinical use since December 2012 , with over 800 patient - years of exposure to the product. • Patient exposure across 6 countries, in subjects ranging from 18 – 89 years of age, having multiple pre - existing co - morbidities. • The HAV has been studied in three different clinical indications: Trauma , AV access , PAD . • Clinical outcomes have shown the HAV is highly resistant to infection , across clinical indications. • The HAV is durable and resists aneurysm formation. • There is no evidence to date of immune sensitization to the HAV. • After implantation, evidence suggests that the HAV repopulates with cells from the patient, reminiscent of living tissue , which may underpin the durability and infection resistance of the HAV. 16

 

 

HUMAYCTE PLATFORM HAS BROAD APPLICATION ACROSS MULTIPLE DISEASES Co r on ary Graft • CABG patients not always ideal for vein stripping: obesity, diabetes • HAVs are designed to be off - the - shelf and universal • 500,000 grafts per year in US Pediatric Heart Surgery • Babies born with heart defects often require repeated heart surgeries • HAVs as BT shunts may grow with the child: no need for repeat surgeries • 10,000+ U.S. babies/year Bio V ascu lar Pancreas • 1.2 million with Type 1 diabetes in U.S. • Insulin palliation is the only therapy, since pancreas transplants are dangerous • HAVs may deliver curative islets and insulin with low risk Trachea • No options exist for patients with tracheal injury • Off - the - shelf engineered airway may integrate into the host • 4,000+ operations per year in US Lung • Lung disease is a growing killer • Transplants are limited by organ shortage • Stem cells can be grown inside of acellular lung matrix to make new lungs H AV BT shunt Engineered Lung 17

3 4 TIME TO RE - VASCULARIZATION IS CRITICAL IN TRAUMA CASES 1) Alarhayem A.Q. et al, 2019; Journal of Vascular Surgery 2) Glass, G. et al. 2009; Journal of Plastic and Reconstructive Surgery. • In vascular trauma: quicker revascularization significantly reduces risk of amputation . 1 • Extending time to revascularization to 6 hours (“clinical standard”) doubles rate of amputation compared to 1 hour. • Steep increase in amputation rate as revascularization time approaches 3 - 4 hours after initial injury. 2 • Lower extremity trauma comprises the clear majority of civilian and military vascular trauma. • With current standard of care (vein, ePTFE), overall amputation rate is approximately 13% 2 • ePTFE rarely used; saphenous vein takes an hour to harvest. Amputation Risk and Revascularization Time

 

 

LIMB SALVAGE IS A DEFENSE DEPARTMENT PRIORITY • In 2018, the DoD listed Humacyte’s HAV as a Medical Product Priority under Public Law 115 - 92. • Public Law 115 - 92 requires enhanced collaborations and communication between the U.S. Department of Defense (DoD) and the U.S. Food and Drug Administration (FDA) on DoD’s Medical Product Priorities for military emergencies. • Public Law 115 - 92 allows the Secretary of Defense to request, and authorizes FDA to take, specific actions to expedite the development of Medical Product Priorities . • Based on Medical Product Priority status, Humacyte and FDA are in discussions to convert V005 from a Phase 2 to a Phase 3 trial . Feasibility of HAV in vascular trauma. Initially 7 clinical sites, US only In 2017, DoD provided a grant for a Humacyte Phase 2 Vascular Trauma Trial. DoD - Funded V005 Trial, Phase 2 35

 

 

ONGOING PHASE 2/3 V005 TRIAL IN VASCULAR TRAUMA Enrollment: Discussions with FDA are ongoing on final trial design (41 subjects enrolled through May 2021); Unblinded trial for repair of vascular traumatic injury. NCT03005418: A Study for the Evaluation of Safety and Efficacy of Humacyte’s Human Acellular Vessel for Vascular Replacement or Reconstruction in Subjects with Life or Limb - threatening Vascular Trauma DOD PRIORITY DESIGNATION Targeting 27 centers in the US, Poland, and Israel. HAV implanted in patients with vascular injury below the neck. (Currently with 20 active centers in the U.S., up from 7 centers in early 2020.) Cohort: Focus analysis on Lower Extremity Trauma (75% of injuries) to speed approval. No Active C o m p ara to r: Single - arm Trial Historical comparators and prior publications of ePTFE efficacy; finalizing with FDA Duration and Objectives: V005 is deemed suitable for Accelerated Approval Pathway.

HAV HAD FEWER REMOVALS THAN ePTFE • For HAVs, 42% had angioplasties with over - sized balloons, and these HAVs had a significant increase in interventions. • When HAVs were handled as directed, interventions were similar for HAV and ePTFE. • In V006, ePTFE grafts had to be removed from patients more often than HAVs. Conduit Removal in V006 Trial 17 12 ~3x ~4x 5 3 Partial F u ll H AV eP T FE 68

 

 

SECONDARY PATENCY WAS HIGHER IN CLINICAL SITES WITH PREVIOUS HAV EXPERIENCE • Kaplan - Meier curve of HAV and ePTFE graft secondary patency at 4 sites with previous HAV experience • HAV secondary patency was 100% until 18 months at sites with prior HAV experience (from Phase 2 studies) 69

 

 

FACTORS POTENTIALLY AFFECTING V006 HUMANITY TRIAL OUTCOMES MONITORING and FOLLOW - UP: • Frequent study - mandated ultrasounds (at 1, 3, 6, 12, 18 and 24 months), which exceed standard of care, provided enhanced ability of surgeons to monitor ePTFE study conduits. • Over 40% of HAVs in the HUMANITY trial had interventions “not as directed” , including the use of over - sized angioplasty balloons that are typically used in ePTFE grafts, but which likely damaged the HAVs. COMPLEX MANAGEMENT and Care Patterns of Dialysis Patients: • Surgeons, as the clinical study Principal Investigators, were not the only physicians/medical staff managing the care of patients or the HAV as the dialysis conduit – Lack of understanding on how to handle the HAV across all aspects of dialysis care after surgical implantation was likely detrimental • Updating ESRD patient practices and management to account for the biological HAV is a key focus – Training and education on how to handle the HAV being implemented across all patient care touch points and applied to V007 - ie. dialysis centers/ technicians, nephrologists, interventionalists. 70

 

 

V006 HUMANITY TRIAL SUPPORTS UTILITY OF HAV IN PATIENTS AT RISK FOR INFECTION OR FISTULA NON - MATURATION 71 • The HUMANITY trial showed that the HAV is safe and functional for dialysis access . • HAV in the HUMANITY trial performed as expected, and predicted, from Phase 2 data. • The performance of the HAV was better than reported historical patency for both ePTFE grafts and AV fistulas. • ePTFE in the HUMANITY trial performed unexpectedly well, compared to historical literature. • HAV had significantly fewer infections than ePTFE, along with fewer hospitalizations for infection. • HAV had fewer PRA increases than ePTFE, implying kidney transplantation may be easier for HAV subjects. • HAV had superior cellular repopulation and healing after implantation, as compared to ePTFE. • Inappropriate handling of the HAV may have impacted relative outcomes in the HUMANITY trial. • Using the pre - specified Cox test, secondary patency for the HAV did not achieve the primary endpoint of non - inferiority (after all subjects were at least 18 months). • HUMANITY results support the proposed utility in patients who are at risk for fistula non - maturation or for access infection. • HUMANITY Trial, combined with V007 Trial and Phase 2 data, will be utilized to support indication in patients at risk for fistula non - maturation or access infection.

 

 

ENROLLING PHASE 3 TRIAL IN DIALYSIS ACCESS VERSUS AV FISTULA (V007) 72 Enrollment: Target 240 total subjects (over 185 subjects enrolled through April 2021);1:1 Prospective randomization HAV (6mm x 42cm) vs. autogenous fistula NCT03183245: Compare the Efficacy and Safety of Humacyte’s Human Acellular Vessel with that of an Autologous Arteriovenous Fistula in Subjects with End - Stage Renal Disease (currently enrolling) 30 centers in the US . HAV implanted in patients in need of dialysis access and who were suitable for single - stage arteriovenous fistula . Comparators: Single - stage arteriovenous fistula in the upper extremity Objectives: • Primary Efficacy: Useability for dialysis at 6 months; Secondary patency at 12 months; • Primary Safety: Compare rates of interventions, infections, host remodeling, and dialysis efficiency Duration: Each subject is followed for 24 months after implantation, irrespective of patency status. Thereafter, all subjects with a HAV irrespective of patency status and only subjects with a patent fistula will be followed for up to 5 years. V007 Trial, combined with HUMANITY Trial and Phase 2 data, will be utilized to support indication in patients at risk for fistula non - maturation or access infection.

 

 

LEARNINGS FROM HUMANITY THAT HAVE BEEN APPLIED TO V007 TRIAL MONITORING and FOLLOW - UP: • Pro - active teaching at all clinical sites around suitable interventions for the HAV : angioplasty balloon size, etc . • Monitoring sites for inappropriate interventions and provide additional, specific instruction to sites and investigators not following V007 trial guidelines. COMPLEX MANAGEMENT and Care Patterns of Dialysis Patients: • Working with Fresenius to provide targeted teaching to dialysis access centers on the use of the HAV in the V007 trial – technicians will not feel a “pop” that accompanies needle puncture of ePTFE. • Emphasizing that ultrasounds are for patency assessment and should not be utilized as a sole basis for intervention on the access conduit . 73

Peripheral Artery Disease (PAD) JACK L. CRONENWETT, M.D. Caused by atherosclerosis • Like coronary heart disease • Most commonly affects legs (can involve any artery) A ge % US Population Prevalence of PAD in U.S. Affects 10 Million Americans > age 40 • Increases with age, > 20% by age 80 Narrowed arteries reduce blood flow • Initial symptom is muscle pain with exercise • Termed Claudication • Can affect all leg arteries • Usually causes calf pain 79

 

 

Peripheral Artery Disease (PAD) JACK L. CRONENWETT, M.D. Can progress to multiple leg arteries, further reducing circulation Treatment requires restoration of blood flow • Non - surgical, catheter - based intervention • Surgical bypass Critical Limb Threatening Ischemia • Tissue does not receive enough blood flow to survive • If untreated, leads to tissue loss, gangrene, and ultimately amputation 80

 

 

Peripheral Artery Disease Treatment JACK L. CRONENWETT, M.D. Peripheral Vascular Intervention (PVI) Balloon Angioplasty or Stenting • Less invasive, percutaneous procedure • Used for less severe disease • Increasing in frequency Surgical Bypass • Used for more severe disease • Different levels based on disease location • Conduit: Synthetic or vein graft • More invasive, especially with vein harvest ~ 50,000 Cases in U.S. per year 81

 

 

Conduit Used for Leg Bypass Surgery JACK L. CRONENWETT, M.D. Saphenous Vein Grafts (54%) • Best patency, lowest reintervention rate • More resistant to infection • Only suitable in ~ half of cases • Require long leg incision to harvest – Increases risk and complications – Other veins (arm) used in only 5% of cases Synthetic Teflon Grafts (35%) • Lower patency, less resistant to infection • Used when veins not available, despite worse outcomes Biologic Grafts (6%) • Human frozen vein/artery or treated bovine arteries • More resistant to infection, subject to degeneration / aneurysm formation • Used in cases with infection or size mis - match when vein not suitable S aph e n o us Vein, 54% Other Veins, 5% T e fl o n, 35% Biologic, 6% Conduit Used in SVS VQI Registry 82

 

 

Leg Bypass Grafts: Current Challenges JACK L. CRONENWETT, M.D. • Saphenous vein grafts often not suitable and require morbid incisions • Synthetic grafts have worse patency, higher reintervention/ amputation • Biologic grafts have worse patency and degeneration Opportunities for HAV in treatment of PAD: • Patients without suitable saphenous vein or cannot tolerate vein harvest • Cases with high infection risk or an infected graft that needs replacement • Half of all leg bypass grafts that are required in current practice Ideal bypass graft: off - the - shelf, require small incisions, infection resistant with good patency with low reintervention rate 83

SMALL DIAMETER HAV IN PEDIATRIC HEART SURGERY Tremendous opportunity to help pediatric patients in numerous applications with BT Shunt identified as a first step The Small Diameter, 3.5mm HAV is currently being investigated as a BT Shunt in a preclinical juvenile primate model using angiography, MRI, ultrasound, and histology to evaluate function. Five primates have been implanted and followed for more than 4 months. 103

SUMMARY AND NEXT STEPS 5 primates have been evaluated with our 3.5mm small diameter HAV implanted as a BT Shunt and followed for 4 - 6 months • Surgeons determined size, handling, ability to suture, and durability of the HAV was appropriate for pediatric cardiac surgery. • Juvenile primate model was challenging due to differing anatomy, however technical success was achieved • Animals appeared to be healthy throughout study (eg, no evidence of heart failure) • Three remained patent until time of explant showing good durability; two additional animals showed evidence of HAV rejection (human - to - macaque cross - species implant). • Remodeling was evident in HAVs • Analysis of histological remodeling and histopathology is ongoing, will be submitted to the FDA in advance of a pre - IND meeting. Next Steps: 106 Submit results for publication Request Pre - IND Meeting with FDA Discuss data with FDA to determine if more data is required prior to initiating Phase I clinical trials

 

 

VIDEO OF CORONARY ARTERY BYPASS IN ADULT BABOON HAV is being tested as a coronary artery bypass graft (CABG) in adult, non - human primates. This video shows a 3.5mm HAV supporting blood flow to the coronary artery of an adult baboon. If successful, data will be utilized for Pre - IND meeting request to support a Phase 1 trial in CABG in patients. 107

 

 

Type 1 Diabetes Dr. Laura Niklason

 

 

109 TYPE 1 DIABETES IS A GROWING HEALTH PROBLEM • Like many other auto - immune diseases, Type 1 diabetes is growing at a rate of 2% in the Western world – cause of this is unknown 1 . • Insulin injections, insulin pumps, finger sticks: $10k/year 2 • Constant vigilance for blood sugar control impairs quality of life . • 1/3rd of patients unable to maintain adequate blood sugar control , leading to kidney failure, blindness, amputation, and heart attacks 3 . Diabetes is Expensive, and Debilitating: 1 in 300 people in US and Europe suffer from Type 1 diabetes. Auto - immune destruction of the islets in the pancreas that sense blood sugar, and secrete insulin in response. 1) Center for Disease Control 2) https://www.businessinsider.com/costs - to - manage - type - 1 - diabetes - 2016 - 9 3) Hoerger, T.J., Diabetes Care, 2008; 31: 81 - 86

 

 

1 1 0 A CURATIVE THERAPY FOR TYPE 1 DIABETES HAS NOT YET ARRIVED 1) https://health.costhelper.com/pancreas - transplant - cost.htm l 2) https://www.kidmey.org/atoz/content/kidpantx 3) CITR 9 th Annual Report, 2016, Collaborative Islet Transplant Registery Pancreas t r ansp l anta t i on is dangerous and expensive: ~ $280,000 1 . Only ~1,000 pancreas transplants done in U.S. last year 2 . Edmonton Protocol – Islets Injected into Liver Portal Vein Beta - Air – Islets in an Oxygen Cannister Islet Transplantation has poor clinical outcomes. • Edmonton Protocol, which is the gold standard, cures only 16% of patients at 2 years 3 . • Islets die in the portal vein because clots and inflammation form around islets, robbing them of oxygen. Islet cannisters under the skin are not practical • Frequent manual injections of oxygen through the skin.

 

 

BIOVASCULAR PANCREAS MAY DELIVER CURATIVE ISLETS TO DIABETICS • Islets die after implantation under the skin, or after injection into the abdomen, due to lack of oxygen and nutrients. • Without a blood supply, pancreatic islets cannot survive transplantation. • Humacyte’s HAV is being developed as a means to provide oxygen and nutrients to islets that are coated on the outside of the vessel : a “ Biovascular Pancreas”, or BVP • Once implanted in the vasculature, blood flow supplies oxygen and nutrients to islets, via diffusion through the HAV wall. • Islets survive and secrete insulin. One 42 - cm HAV can accommodate all of the islets in an entire human pancreas. Islets + HAV = Biovascular Pancreas (BVP) Blood flow supports islets BVP Implanted in the arm 111
