Acellular Tissue Engineered Vessel

1 INDICATIONS AND USAGE SYMVESS™ is an acellular tissue engineered vessel indicated for use in adults as a vascular conduit for extremity arterial injury when urgent revascularization is needed to avoid imminent limb loss, and autologous vein graft is not feasible.

6 ADVERSE REACTIONS The most common adverse reactions (incidence ≥3%) were thrombosis, fever, pain, anastomotic stenosis, rupture or anastomotic failure, and infection. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Humacyte Global, Inc. at 1-833-591-0081 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a product cannot be directly compared to adverse reaction rates in clinical trials of other products, and they may not reflect the rates observed in real-world clinical practice.

8.1 Pregnancy Risk Summary The limited clinical data that are available with SYMVESS use in pregnant women are insufficient to inform a drug-associated risk. No animal reproductive and developmental toxicity studies have been conducted with SYMVESS to assess whether it can cause harm to the mother or fetus when administered to a pregnant woman. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

WARNING: GRAFT FAILURE Loss of SYMVESS integrity due to mid-graft rupture or anastomotic failure can result in life threatening hemorrhage. [See Warnings and Precautions (5.1 , 5.2) ] WARNING: GRAFT FAILURE See full prescribing information for complete boxed warning. Loss of SYMVESS integrity due to mid-graft rupture or anastomotic failure can result in life threatening hemorrhage. ( 5.1 , 5.2 ) 5 WARNINGS AND PRECAUTIONS Graft Rupture. ( 5.1 ) Anastomotic Failure. ( 5.2 ) Thrombosis. ( 5.3 ) Transmission of Infectious Diseases ( 5.4 ) 5.1 Graft Rupture Vascular graft rupture has occurred in patients treated with SYMVESS [see Clinical Trials Experience (6.1) ] . Advise patients that arterial bleeding can be life-threatening and to seek emergent medical evaluation for any signs or symptoms of graft rupture such as bleeding, pain and swelling in the extremity, or signs of extremity ischemia. Follow appropriate procedures for handling and administering SYMVESS [see Dosage and Administration (2) ] . 5.2 Anastomotic Failure Anastomotic failure has occurred in patients treated with SYMVESS [see Clinical Trials Experience (6.1) ] . 4 CONTRAINDICATIONS DO NOT use SYMVESS in patients who have a medical condition that would preclude long-term antiplatelet therapy (such as aspirin or clopidogrel) after resolution of acute injuries.
