The most common adverse reactions reported in >1% of patients during clinical trials were anemia, nausea and vomiting, fever, abdominal pain, increased white blood cell count, ascites, itching, atrial fibrillation, pleural effusion, gastrointestinal hemorrhage, wound infection, hypophosphatemia, urinary tract infection and post-procedural bile leakage in hepatic surgery. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Corza Medical GmbH at 1-800-997-1067 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 drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Cardiovascular Surgery In the cardiovascular trial, the most frequently reported adverse reactions were atrial fibrillation and pleural effusion. Seventy-four percent (74%) of patients treated with TachoSil and 75% of comparator treated patients experienced one or more clinically relevant adverse reactions (see Table 2). Table 2. Most Frequent Adverse Reactions (Cardiovascular Trial) Adverse Reaction TachoSil Comparator Comparator: Hemostatic fleece material without additional active coagulation stimulating compounds. N = 62 As treated population (safety data set). n (%) N = 57 n (%) Atrial fibrillation 18 (29%) 14 (25%) Pleural effusion 14 (23%) 11 (19%) Pyrexia 4 (6%) 3 (5%) Hepatic Surgery In the hepatic surgery trial, the most frequently reported adverse reactions were nausea and anemia (see Table 3). Ninety-four percent (94%) of patients treated with TachoSil and 94% of comparator treated patients experienced one or more clinically relevant adverse reactions. Table 3. Most Frequent Adverse Reactions (Hepatic Resection Trial) Adverse Reaction TachoSil Comparator Comparator: Hemostatic fleece material without additional active coagulation stimulating compounds. N = 114 As treated population (safety data set). n (%) N = 109 n (%) Nausea 34 (30%) 29 (27%) Anemia 26 (23%) 23 (21%) Post-operative bile leakage was observed in 8 (7%) of patients after treatment with TachoSil and 13 (12%) after treatment with comparator. Immunogenicity Antibodies against components of fibrin sealant/hemostatic products may occur. However in a clinical trial with human fibrinogen/human thrombin sponge (patch) in hepatic surgery, in which patients were investigated for the development of antibodies, 26% of the 96 patients tested and treated with human fibrinogen/human thrombin sponge (patch) developed antibodies to equine collagen.

Thrombin human and fibrinogen dosage

Quoted from the “Dosage and Administration” section of the FDA-approved label. Your own dose is the one your doctor prescribes: do not change it on your own.

For topical use on cardiovascular or hepatic tissue only Determine the number of patches to be applied by the size of the bleeding area. Apply the yellow, active side of the patch to the bleeding area. When applying TachoSil, do not exceed the maximum number of patches shown in Table 1 [see Warnings and Precautions (5.6)]. Table 1.

Amount of Fibrinogen and Thrombin per Total Patch Size and Maximum Number of TachoSil Patches to be Applied TachoSil Patch Size Human Fibrinogen (mg) Human Thrombin (Units) Maximum Number of Patches to be Applied 3.7 inch x 1.9 inch (9.5 cm x 4.8 cm) 337.4 123.1 10 1.9 inch x 1.9 inch (4.8 cm x 4.8 cm) 170.5 62.2 14 Apply on the surface of cardiovascular or hepatic tissue only.

• Determine the number of TachoSil patches to be applied by the size of the bleeding area. (2)
• Apply the yellow, active side of the patch to the bleeding surface. (2) 2.1 Preparation for Application TachoSil comes ready to use in sterile packages and must be handled using sterile technique in aseptic conditions. Discard damaged packages as resterilization is not possible. When in the operating room, the outer aluminum foil pouch may be opened in a non-sterile environment (Fig. 1A). The inner sterile blister must be opened in a sterile environment (Fig. 1B). Remove the TachoSil patch from the blister (Fig. 1C), which can be used as a container for pre-moistening of the patch, if needed. Determine the size of patch(es) to be applied to the bleeding surface. Select the appropriate TachoSil patch so that it extends 1 to 2 cm beyond the margins of the wound. The patch can be cut to the correct size and shape if desired (Fig. 1D). If more than one patch is used, overlap patches by at least 1 cm. Prior to application, cleanse the area to be treated to remove disinfectants and other fluids. The fibrinogen and thrombin proteins can be denatured by alcohol, iodine or heavy metal ions. If any of these substances have been used to clean the wound area, thoroughly irrigate the area before the application of TachoSil. Apply TachoSil directly to the bleeding area either wet or dry. If applied wet, pre-moisten TachoSil in 0.9% saline solution and then apply immediately. In the case of a wet tissue surface (e.g., oozing bleeding) TachoSil may be applied without pre-moistening. Figure 1: Pictures illustrating steps for preparation for application of TachoSil A B C D 21a 21b 21c 21d 2.2 Method of Application To ensure TachoSil adheres effectively, follow the recommended handling, preparation, and application procedures. Incorrect handling may result in non-adherence and reduced efficacy of TachoSil. Cleanse surgical instruments, gloves and adjacent tissues with saline solution to reduce the adherence to the TachoSil patch. The white, inactive side of TachoSil may also adhere to surgical instruments (e.g., forceps), gloves or adjacent tissues covered with blood due to the affinity of collagen to blood. It is important to note that failure to adequately clean adjacent tissues may cause adhesions [see Warnings and Precautions (5.4)].
