FULL PRESCRIBING INFORMATION
1 INDICATIONS AND USAGE
1.1 Control and Prevention of Bleeding Episodes
Kogenate® FS is an antihemophilic factor that is indicated for the control and prevention of bleeding episodes in adults and children (0-16 years) with hemophilia A.
1.2 Peri-operative Management
Kogenate FS is indicated for surgical prophylaxis in adults and children with hemophilia A.
1.3 Routine Prophylaxis in Children with Hemophilia A with No Pre-existing Joint Damage
Kogenate FS is indicated for routine prophylactic treatment to reduce the frequency of bleeding episodes and the risk of joint damage in children with no pre-existing joint damage.
Kogenate FS is not indicated for the treatment of von Willebrand’s disease.
2 DOSAGE AND ADMINISTRATION
For Intravenous Use After Reconstitution
- Treatment with Kogenate FS should be initiated under the supervision of a physician experienced in the treatment of hemophilia A.
- Each vial of Kogenate FS has the recombinant factor VIII (rFVIII) potency in international units stated on the label.
- Dosage and duration of treatment depend on the severity of the factor VIII deficiency, the location and extent of bleeding, and the patient’s clinical condition.1 Careful control of replacement therapy is especially important in cases of major surgery or life-threatening bleeding episodes. [See Table 1 and Table 2.]
The expected in vivo peak increase in factor VIII level expressed as IU/dL (or % normal) can be estimated using the following formulas:
Dosage (units) = body weight (kg) x desired factor VIII rise (IU/dL or % or normal) x 0.5 (IU/kg per IU/dL)
OR
IU/dL (or % normal)=Total Dose (IU)/body weight (kg) x 2 [IU/dL]/[IU/kg]
Examples (assuming patient’s baseline factor VIII level is <1% of normal):
- A dose of 1750 IU Kogenate FS administered to a 70 kg patient should be expected to result in a peak post-infusion factor VIII increase of 1750 IU x {[2 IU/dL]/[IU/kg]}/[70 kg] = 50 IU/dL (50% of normal).
- A peak level of 50% is required in a 15 kg child. In this situation, the appropriate dose would be:
50 IU/dL/{[2 IU/dL]/[IU/kg]} x 15 kg = 375 IU.
Doses administered should be titrated to the patient’s clinical response. Patients may vary in their pharmacokinetic (e.g., half-life, in vivo recovery) and clinical responses to Kogenate FS.2,3,4 Although the dose can be estimated by the calculations above, it is highly recommended that, whenever possible, appropriate laboratory tests including serial factor VIII activity assays be performed. [See Warnings and Precautions (5.4) and Clinical Pharmacology (12.3).]
2.1 Control and Prevention of Bleeding Episodes
The careful control of treatment dose is especially important in cases of life-threatening bleeding episodes or major surgery.
The following table can be used to guide dosing in bleeding episodes.
| Type of Bleeding Episode | Factor VIII Level Required (IU/dL or % of normal) | Dosage and Frequency Necessary to Maintain the Therapeutic Plasma Level |
|
Minor Early hemarthrosis, minor muscle or oral bleeds. | 20–40 |
10–20 IU per kg Repeat dose if there is evidence of further bleeding. |
|
Moderate Bleeding into muscles, bleeding into the oral cavity, definite hemarthroses, and known trauma. | 30–60 |
15–30 IU per kg Repeat dose every 12–24 hours until bleeding is resolved. |
|
Major Gastrointestinal bleeding. Intracranial, intra-abdominal or intrathoracic bleeding, central nervous system bleeding, bleeding in the retropharyngeal or retroperitoneal spaces, or iliopsoas sheath. Fractures. Head trauma. | 80–100 |
Initial dose 40–50 IU per kg Repeat dose 20–25 IU per kg every 8–12 hours until bleeding is resolved. |
2.2 Peri-operative Management
The careful control of treatment dose is especially important in cases of major surgery or life-threatening bleeding episodes.
The following table can be used to guide dosing in surgery:
| Type of Surgery | Factor VIII Level Required (IU/dL or % of normal) | Dosage and Frequency Necessary to Maintain the Therapeutic Plasma Level |
|
Minor Including tooth extraction | 30–60 |
15–30 IU per kg Repeat dose every 12–24 hours until bleeding is resolved. |
|
Major Examples include tonsillectomy, inguinal herniotomy, synovectomy, total knee replacement, craniotomy, osteosynthesis, trauma. | 100 |
Pre-operative dose 50 IU per kg Verify 100% activity prior to surgery. Repeat as necessary after 6 to 12 hours initially, and for 10 to 14 days until healing is complete. |
2.3 Routine Prophylaxis in Children with No Pre-existing Joint Damage.
The recommended dose for routine prophylaxis is 25 IU/kg of body weight every other day.5
2.4 Instructions for Use
Kogenate FS is administered by intravenous (IV) injection after reconstitution. Patients should follow the specific reconstitution and administration procedures provided by their physicians.
For instructions, patients should follow the recommendations in the FDA-Approved Patient Labeling. [See FDA-Approved Patient Labeling (17).]
Reconstitution, product administration, and handling of the administration set and needles must be done with caution. Percutaneous puncture with a needle contaminated with blood can transmit infectious viruses including HIV (AIDS) and hepatitis. Obtain immediate medical attention if injury occurs. Place needles in a sharps container after single use. Discard all equipment, including any reconstituted Kogenate FS product, in an appropriate container.
2.5 Preparation and Reconstitution
The procedures below are provided as general guidelines for the reconstitution and administration of Kogenate FS with BIO-SET®, a needleless self-contained reconstitution system. Always work on a clean surface and wash hands before performing the following procedures.
Vacuum Transfer and Reconstitution
- Warm the unopened diluent (as needed) and the concentrate to a temperature not to exceed 37°C or 99°F.
- Remove the cap from the concentrate. Take out the prefilled diluent syringe and remove the tip cap. (Fig. A).
- Connect the prefilled diluent syringe to the concentrate vial by gently screwing on to the BIO-SET connection (Fig. B).
- Place the vial on a rigid, non-skid surface and hold it firmly with one hand. With the other hand, strongly press down the fingerplate near the syringe tip using your thumb and index finger (Fig. C) until the fingerplate meets the top edge of the BIO-SET. This confirms that the system is activated (Fig. D).
- Grasp the plunger rod by the top plate and remove from carton. Avoid touching the sides and threads of the plunger rod. Immediately screw plunger rod into the syringe rubber stopper (Fig. E).
- Inject the diluent into the concentrate by pushing down the plunger rod slowly (Fig. F).
- Swirl gently until completely dissolved without creating excessive foaming (Fig. G).
- Kogenate FS should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
- Invert vial/syringe and transfer the solution into syringe that was used to deliver the diluent (Fig. H). Ensure that the entire contents of the reconstituted Kogenate FS vial are drawn into the syringe.
- Unscrew the filled syringe to disconnect it from the empty concentrate vial (Fig. I).
- Attach the filled syringe to the administration set provided and immediately inject intravenously (Fig. J). NOTE: See accompanying instructions for Infusion Set with Filter.
- If the same patient is to receive more than one vial, the diluent syringe provided should be used to reconstitute the powder in the product vials as described above. The reconstituted solutions should then be combined in a larger plastic syringe (not provided) and administered as usual (Fig. J).
2.6 Administration
For Intravenous Use Only After Reconstitution
- Kogenate FS should be inspected visually for particulate matter and discoloration prior to administration, wherever solution and container permit. Turbid or discolored solution should be discarded.
- Reconstituted Kogenate FS may be stored at room temperature prior to administration, but is to be administered within 3 hours. It is recommended to use the IV administration set provided.
- A dose of Kogenate FS may be administered over a period of 1 to 15 minutes. The rate of administration however, should be adapted to the response of each individual patient. The pulse rate should be determined before and during administration of Kogenate FS. If there is a significant increase in pulse rate, reducing the rate of administration or temporarily halting the injection allows the symptoms to disappear promptly.
3 DOSAGE FORMS AND STRENGTHS
Kogenate FS is available as a lyophilized powder in single use glass vials containing 250, 500, 1000, 2000, and 3000 International Units (IU).
Each vial of Kogenate FS is labeled with the recombinant antihemophilic factor activity expressed in IU per vial. This potency assignment employs a factor VIII concentrate standard that is referenced to a WHO International Standard for factor VIII concentrates, and is evaluated by appropriate methodology to ensure accuracy of the results.
4 CONTRAINDICATIONS
Kogenate FS is contraindicated in patients who have manifested life-threatening immediate hypersensitivity reactions, including anaphylaxis, to the product or its components, including mouse or hamster proteins.
5 WARNINGS AND PRECAUTIONS
5.1 General
The clinical response to Kogenate FS may vary. If bleeding is not controlled with the recommended dose, the plasma level of factor VIII should be determined and a sufficient dose of Kogenate FS should be administered to achieve a satisfactory clinical response. If the patient’s plasma factor VIII level fails to increase as expected or if bleeding is not controlled after the expected dose, the presence of an inhibitor (neutralizing antibodies) should be suspected and appropriate testing performed. [See Warnings and Precautions (5.4).]
5.2 Anaphylaxis and Severe Hypersensitivity Reactions
Allergic-type hypersensitivity reactions including anaphylaxis have been reported with Kogenate FS and have manifested as pruritus, rash, urticaria, hives, facial swelling, dizziness, hypotension, nausea, chest discomfort, cough, dyspnea, wheezing, flushing, discomfort (generalized) and fatigue. Discontinue Kogenate FS if symptoms occur and seek immediate emergency treatment.
Kogenate FS contains trace amounts of mouse immunoglobulin G (MuIgG) and hamster (BHK) proteins. Patients treated with this product may develop hypersensitivity to these non-human mammalian proteins.
5.3 Neutralizing Antibodies
Patients treated with antihemophilic factor (AHF) products should be carefully monitored for the development of factor VIII inhibitors by appropriate clinical observations and laboratory tests.6 Inhibitors have been reported following administration of Kogenate FS predominantly in previously untreated patients. If expected plasma factor VIII activity levels are not attained, or if bleeding is not controlled with an expected dose, an assay that measures factor VIII inhibitor concentration should be performed.[See Warnings and Precautions (5.4).]
5.4 Monitoring Laboratory Tests
- Monitor plasma factor VIII activity levels by the one-stage clotting assay to confirm the adequate factor VIII levels have been achieved and maintained, when clinically indicated. [See Dosage and Administration (2).]
- Monitor for development of factor VIII inhibitors. Perform assay to determine if factor VIII inhibitor is present. If expected factor VIII activity plasma levels are not attained, or if bleeding is not controlled with the expected dose of Kogenate FS. Use Bethesda Units ( BU) to titer inhibitors.
- If the inhibitor is less than 10 BU per mL, the administration of additional Kogenate FS concentrate may neutralize the inhibitor, and may permit an appropriate hemostatic response.
Adequate hemostasis may not be achieved if Inhibitor titers are above 10 BU per mL. The inhibitor titer may rise following Kogenate FS infusion as a result of an anamnestic response to factor VIII. The treatment or prevention of bleeding in such patients requires the use of alternative therapeutic approaches and agents.
6 ADVERSE REACTIONS
The most serious adverse reactions are systemic hypersensitivity reactions including bronchospastic reactions and/or hypotension and anaphylaxis and the development of high-titer inhibitors necessitating alternative treatments to AHF.
The most common adverse reactions observed in clinical trials (frequency ≥ 4% of patients) are inhibitor formation in previously untreated patients (PUPs) and minimally treated patients (MTPs), skin-related hypersensitivity reactions (e.g., rash, pruritus), infusion site reactions (e.g., inflammation, pain), and central venous access device (CVAD) line-associated infections in patients requiring a CVAD for intravenous administration.
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 clinical trials of another drug and may not reflect the rates observed in clinical practice.
Previously Treated Patients (PTPs)
During the clinical studies conducted in PTPs, 451 adverse events (irrespective of the relationship to the study drug) were reported in the course of 24,936 infusions (1.8%). Twenty-four of the 451 adverse events were assessed as related to Kogenate FS (0.1%).

Immunogenicity
In clinical studies with 73 PTPs (defined as having more than 100 exposure days), one patient had a pre-existing inhibitor. In the other 72 patients, followed over 4 years, no de-novo inhibitors were observed.
In clinical studies with pediatric PUPs and MTPs, inhibitor development was observed in 9 out of 60 patients (15%), 6 were high titer1 (>5BU) and 3 were low-titer inhibitors. Inhibitors were detected at a median number of 7 exposure days (range 2 to 16 exposure days).
In the Joint Outcome Study with Kogenate FS,5 de-novo inhibitor development was observed in 8 of 64 patients with negative baseline values (12.5%), 2 patients developed high titer1 (>5 BU) and were withdrawn from the study. Six patients developed low-titer inhibitors. Inhibitors were detected at a median number of 44 exposure days (range 5 to 151 exposure days).
6.2 Post-Marketing Experience
The following adverse reactions have been identified during post approval use of Kogenate FS. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Among patients treated with Kogenate FS, cases of serious allergic/hypersensitivity reactions (which may include facial swelling, flushing, hives, blood pressure decrease, nausea, rash, restlessness, shortness of breath, tachycardia, tightness of the chest, tingling, urticaria, vomiting) have been reported, particularly in very young patients or patients who have previously reacted to other factor VIII concentrates.
The following table represents the post-marketing adverse reactions as MedDRA Preferred Terms.

| Immune System Disorders | Anaphylactic reaction, other hypersensitivity reactions |
7 DRUG INTERACTIONS
None known.
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Pregnancy Category C.
Animal reproduction studies have not been conducted with Kogenate FS. It is also not known whether Kogenate FS can cause fetal harm when administered to a pregnant woman or affect reproduction capacity. Kogenate FS should be used during pregnancy only if clinically needed.
8.2 Labor and Delivery
There is no information available on the effect of factor VIII replacement therapy on labor and delivery. Kogenate FS should be used only if clinically needed.
8.3 Nursing Mothers
It is not known whether this drug is excreted into human milk. Because many drugs are excreted into human milk, caution should be exercised if Kogenate FS is administered to nursing mothers. Kogenate FS should be given to nursing mothers only if clinically needed.
8.4 Pediatric Use
Safety and efficacy studies have been performed in previously untreated and minimally treated pediatric patients. Children in comparison to adults present higher factor VIII clearance values and thus lower recovery of factor VIII. This may be explained by differences in body composition7 and should be taken into account when dosing or following factor VIII levels in such a population. [See Clinical Pharmacology ( 12.3).] Routine prophylactic treatment in children ages 0-2.5 years with no pre-existing joint damage has been shown to reduce spontaneous joint bleeding and the risk of joint damage. This data can be extrapolated to ages >2.5-16 years for children who have no existing joint damage. [See Clinical Studies (14).]
8.5 Geriatric Use
Clinical studies with Kogenate FS did not include patients aged 65 and over. Dose selection for an elderly patient should be individualized.
11 DESCRIPTION
Kogenate FS Antihemophilic Factor (Recombinant) is a coagulation factor VIII produced by recombinant DNA technology. It is produced by Baby Hamster Kidney (BHK) cells into which the human factor VIII gene has been introduced.8 The cell culture medium contains Human Plasma Protein Solution (HPPS) and recombinant insulin, but does not contain any proteins derived from animal sources. Kogenate FS is a purified glycoprotein consisting of multiple peptides including an 80 kD and various extensions of the 90 kD subunit. It has the same biological activity as factor VIII derived from human plasma. No human or animal proteins, such as albumin, are added during the purification and formulation processes of Kogenate FS.
The purification process includes a solvent/detergent virus inactivation step in addition to the use of the purification methods of ion exchange chromatography, monoclonal antibody immunoaffinity chromatography, along with other chromatographic steps designed to purify recombinant factor VIII and remove contaminating substances.
Additionally, the manufacturing process was investigated for its capacity to decrease the infectivity of an experimental agent of transmissible spongiform encephalopathy (TSE), considered as a model for the vCJD and CJD agents.9-21 Several of the individual production and raw material preparation steps in the Kogenate FS manufacturing process have been shown to decrease TSE infectivity of that experimental model agent. TSE reduction steps include the Fraction II+III separation step for HPPS (6.0 log10) and an anion exchange chromatography step (3.6 log10).
Kogenate FS is formulated with the following as stabilizers [see Table 7] in the final container and is then lyophilized. The final product is a sterile, nonpyrogenic, preservative-free, powder preparation for intravenous (IV) injection. Intravenous administration of sucrose contained in Kogenate FS will not affect blood glucose levels.
| Stabilizer | 250 IU, 500 IU, 1000 IU | 2000 IU, 3000 IU |
| Sucrose | 0.9–1.3% | 0.9–1.2% |
| Glycine | 21–25 mg/mL | 20–24 mg/mL |
| Histidine | 18–23 mmol/L | 17–22 mmol/L |
The following inactive ingredients/excipients are also contained in the final product:
| Inactive Ingredient/Excipient | 250 IU, 500 IU, 1000 IU | 2000 IU, 3000 IU |
| Sodium | 27–36 mEq/L | 26–34 mEq/L |
| Calcium | 2.0–3.0 mmol/L | 1.9–2.9 mmol/L |
| Chloride | 32–40 mEq/L | 31–38 mEq/L |
| Polysorbate 80 | 64–96 µg/mL | 64–96 µg/mL |
| Sucrose | 28 mg/vial | 52 mg/vial |
| Imidazole, tri-n-butyl phosphate, and copper | Trace amounts | Trace amounts |
Each vial of Kogenate FS contains the labeled amount of recombinant factor VIII in international units (IU). One IU, as defined by the World Health Organization standard for blood coagulation factor VIII, human, is approximately equal to the level of factor VIII activity found in 1 mL of fresh pooled human plasma.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Kogenate FS temporarily replaces the missing clotting factor VIII that is needed for effective hemostasis.
12.2 Pharmacodynamics
The aPTT is prolonged in patients with hemophilia. Determination of activated partial thromboplastin time (aPTT) is a conventional in vitro assay for biological activity of factor VIII. Treatment with Kogenate FS normalizes the aPTT over the effective dosing period.
12.3 Pharmacokinetics
The pharmacokinetic properties of Kogenate FS were investigated in two separate studies in previously treated patients, adults and children.
Pharmacokinetic studies with Kogenate FS were conducted in 20 PTPs (ages 12 to 33 years) with severe hemophilia A in North America. The pharmacokinetic parameters for Kogenate FS were measured in a randomized, crossover clinical trial with the predecessor KOGENATE product with a single dose administration of 50 IU/kg. After 24 weeks, the same dose of Kogenate FS was administered to the same patients. The recovery and half-life data for Kogenate FS were unchanged after 24 weeks of continued treatment with sustained efficacy and no evidence of factor VIII inhibition. [See Table 9.]
| Parameter | Kogenate FS | KOGENATE | |
| Initial PK Mean (±SD) | PK at week 24 Mean (±SD) | Reference Mean (±SD) | |
| AUC (IU • h/dL) | 1588.05 ± 344.32 | 1487.08 ± 381.73 | 1879.02 ± 412.32 |
| Cmax (IU/dL) | 114.95 ± 20.19 | 109.42 ± 20.09 | 127.40 ± 33.21 |
| Half-life (hr) | 13.74 ± 1.82 | 14.60 ± 4.38 | 14.07 ± 2.62 |
| In Vivo Recovery (IU/dL / IU/kg) | 2.20 ± 0.34 | 2.11 ± 0.37 | 2.43 ± 0.60 |
The pharmacokinetics of Kogenate FS were investigated in pediatric PTPs (4.4-18.1 years of age, average age 12).7 The pharmacokinetic parameters in children compared to adults show differences in higher clearance, lower incremental in vivo factor VIII recovery and a shorter factor VIII half-life. This might be explained by differences in body composition such as body surface area and plasma volume. The pharmacokinetic parameters are depicted in Table 10.
| Parameter | Mean (range) |
| AUC (IU • h/dL) | 1320.0 |
| Clearance (mL/h•kg) | 4.1 |
| Half-life (hr) | 10.7 (7.8–15.3) |
| In Vivo Recovery (IU/dL / IU/kg) | 1.9 (1.25–2.76) |
13 NONCLINICAL TOXICOLOGY
Preclinical studies evaluating Kogenate FS in hemophilia A with mice, rats, rabbits, and dogs demonstrated safe and effective restoration of hemostasis. Doses several fold higher than the recommended clinical dose (related to body weight) did not demonstrate any acute or subacute toxic effect for Kogenate FS in laboratory animals.
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
No studies have been conducted with Kogenate FS to assess its mutagenic or carcinogenic potential and impairment of fertility. Kogenate FS has been shown to be comparable to the predecessor product with respect to its biochemical and physiochemical properties, as well as its non-clinical in vivo pharmacology and toxicology. By inference, the predecessor product and Kogenate FS would be expected to have equivalent mutagenic and carcinogenic potential.
The predecessor product did not demonstrate reverse mutation or chromosomal aberrations at doses substantially greater than the maximum expected clinical dose. In vivo evaluation with the predecessor product in animals using doses ranging between 10 and 40 times the expected clinical maximum also indicated that the predecessor product did not possess a mutagenic potential. Long-term investigations of carcinogenic potential in animals have not been performed due to the immune response to heterologous proteins in all non-human mammalian species.
14 CLINICAL STUDIES
14.1 Previously Treated Patients (PTPs)
A total of 73 patients with severe (≤ 2% FVIII) hemophilia A, ages 12–59, who had been previously treated with other recombinant or with plasma-derived AHF products, were treated up to 54-months in open label studies with Kogenate FS in Europe and North America. A total of 5,684 bleeding episodes were treated during the studies. Patients could be treated on demand or on prophylaxis. Regularly scheduled prophylaxis treatment represented 76% of all infusions (treatment regimens of 2-3 infusions per week). [See Table 11.]
| Clinical Parameters | Results |
| No. of Infusions of Kogenate FS Administered | 24,924 |
| No. of IU Administered | 45 million IU |
| No. of Bleeds Treated with Kogenate FS | 5,684 |
| Percentage of Bleeds Treated with One or Two Infusions of Kogenate FS |
one infusion: 79.7%, two infusions: 13.0% total: 92.7% |
| Mean Kogenate FS Dose per Treatment Infusion (in Europe and North America, Respectively) | Approximately 32.5 and 29.6 IU/kg per treatment infusion |
A total of 31 patients received Kogenate FS for 43 surgical procedures during the PTP studies. There were both minor and major surgery types, 27 and 16 respectively. The surgeon or treating physician assigned a rating to the hemostatic outcome according to 4 categories; “excellent”, “good,” “moderate,” or “none.” Hemostasis was rated as satisfactory (“excellent” or “good”) in all cases. [See Table 13.]
14.2 Previously Untreated and Minimally Treated Patients (PUPs and MTPs)
Kogenate FS has been used in the treatment of bleeding episodes in pediatric previously untreated patients (PUPs) and minimally treated patients (MTPs) with severe (< 2% FVIII) hemophilia A. There were 37 PUPs and 24 MTPs (defined as having equal to or less than 4 exposure days) treated with a total of 9,419 infusions of Kogenate FS for a follow up duration up to 3.1 years. A total of 1047 bleeding episodes were treated.
| Clinical Parameters | Results |
| No. of Infusions of Kogenate FS Administered | 9,419 |
| No. of Exposure Days to Kogenate FS (median) | 115 exposure days |
| No. of IU Administered | 7.5 million IU |
| No. of Bleeds Treated with Kogenate FS | 1,047 |
| Percentage of Bleeds Treated with One or Two Infusions of Kogenate FS |
one infusion 73.1% two infusions 15.0% total: 88.1% |
A total of 29 surgical procedures were performed in 23 patients during the PUPs and MTPs study. There were both minor and major surgery types, 23 and 6 respectively. The surgeon or treating physician assigned a rating to the hemostatic outcome according to 4 categories; “excellent,” “good,” “moderate,” or “none.” Hemostasis was rated as satisfactory (“excellent” or “good”) in all cases. [See Table 13.]
| Type of Surgery | PTPs (N=31) | PUPs/MTPs (N=23) | ||
| No. of Surgical Events | Outcome “Good” or “Excellent” | No. of Surgical Events | Outcome “Good” or “Excellent” | |

|
Major Surgery (i.e., joint replacements, craniotomies, gastrointestinal resection) | 16 | 100% | 6 | 100% |
| Total | 43 | 29 | ||
14.3 Pediatric Prophylaxis and Joint Damage Risk Reduction
A total of 65 boys less than 30 months of age with severe hemophilia A (FVIII level ≤ 2 IU/dL) and with ≤ 2 bleeds into each index joint and normal baseline joint imaging, were observed for up to 5.5 years in a multicenter, open-label, prospective, randomized, controlled clinical study.5 Patients received either 25 IU/kg every other day (primary prophylaxis; n=32) or at least 3 doses totaling a minimum of 80 IU/kg at the time of a bleeding episode (enhanced episodic; n=33). Joint damage was evaluated by magnetic resonance imaging (MRI) or radiography, as well as the frequency of bleeding episodes. Joint damage detected by MRI or radiography in the ankles, knees, and elbows (i.e., index joints) was statistically significantly lower (p=0.002) for subjects receiving prophylactic therapy (7%) than for subjects receiving episodic therapy (42%). This corresponds to a 6.29-fold relative risk of joint damage for subjects treated with enhanced episodic therapy compared to prophylaxis. The mean rate of index joint hemorrhages for subjects on episodic therapy was 4.89 bleeds per year, versus 0.63 bleeds per year observed in the prophylaxis arm. Three of 33 (9.1%) of subjects in the episodic arm experienced recurrent life threatening bleeds (intracranial, gastrointestinal) compared to no subjects in the prophylaxis arm. On a per joint basis, joints in the regular prophylaxis arm were 8-fold more likely to remain damage-free than those in the episodic arm. Joint damage was most frequently observed in ankle joints and was detected at higher rates by MRI than by radiography. Ankles were also the index joint that demonstrated the highest frequency of bleeding events in this study (left ankle, mean 2.7 hemorrhages; right ankle, mean 2.6 hemorrhages).
As shown in Table 14 below, the incidence of joint damage was statistically significantly lower in the prophylactic group as compared to the episodic treatment group when assessed by MRI, or either MRI or radiography, using predefined criteria (described below) for establishing joint damage. However, there was no statistically significant difference between the two groups when joint damage was assessed by radiography alone.
To evaluate joint damage, MRIs were scored using a scale developed by Nuss et al. ,22 and X-rays were scored using the method of Pettersson et al.23 Both scales have been validated in various clinical trials and are routinely used for joint damage evaluation in hemophiliacs. Joint damage was defined as bone and/or cartilage damage including subchondral cysts, erosions and cartilage loss with narrowing of joint space. This corresponded to a total MRI score of ≥7 or an X-ray score of ≥ 1 in any of the following categories: subchondral cysts, erosions of joint surfaces or narrowing of joint spaces. Images were read separately by two independent radiologists centrally. Any discrepant reading was read by an independent third radiologist who was not aware of the initial reading results. The concordant reading of two out of three readers was used for analysis purposes.

Relative Risk is the risk of damage to one or more index joints on the given therapy as compared to the other therapy.
P-value is from the 2-sided Fisher Exact Test comparing the incidence of joint damage between treatment groups.
As shown in Table 15 below, the assessment of endpoints in all randomized subjects assuming that those without complete baseline and endpoint data are treatment failures (intention-to-treat analysis). The incidence of joint damage was statistically significantly lower in the prophylactic group as compared to the episodic treatment group, with similar p-values, when assessed by MRI, or either MRI or radiography.

17 PATIENT COUNSELING INFORMATION
See Patient Product Information and Instructions for Use
Advise patients to report any adverse reactions or problems following Kogenate FS administration to their physician or healthcare provider.
- Allergic-type hypersensitivity reactions have been reported with Kogenate FS. Warn patients of the early signs of hypersensitivity reactions [including hives (rash with itching), generalized urticaria, tightness of the chest, wheezing, hypotension] and anaphylaxis. Advise patients to discontinue use of the product if these symptoms occur and seek immediate emergency treatment with resuscitative measures such as the administration of epinephrine and oxygen.
- In clinical studies with Kogenate FS, a 15% incidence of inhibitor development was observed in PUPs/MTPs and zero de-novo inhibitors were observed with the PTPs. Inhibitor formation may occur at any time in the treatment of a patient with hemophilia A. Advise patients to contact their physician or treatment center for further treatment and/or assessment, if they experience a lack of clinical response to factor VIII replacement therapy, as this may be a manifestation of an inhibitor.

FDA-Approved Patient Labeling
Kogenate FS (kō-jen-ate)
Antihemophilic Factor (Recombinant)
Formulated with Sucrose
This leaflet summarizes important information about Kogenate FS with BIO-SET, a needleless self-contained reconstitution system. Please read it carefully before using this medicine. This information does not take the place of talking with your healthcare provider, and it does not include all of the important information about Kogenate FS. If you have any questions after reading this, ask your healthcare provider.
Do not attempt to self-infuse unless you have been taught how by your healthcare provider or hemophilia center.
What is Kogenate FS?
Kogenate FS is a medicine used to replace clotting factor (factor VIII or antihemophilic factor) that is missing in people with hemophilia A (also called “classic” hemophilia). Hemophilia A is an inherited bleeding disorder that prevents blood from clotting normally.
Kogenate FS is used to prevent and control bleeding in adults and children (0-16 years) with hemophilia A. Your healthcare provider may give you Kogenate FS when you have surgery. Kogenate FS can reduce the number of bleeding episodes when used regularly and reduce the risk of joint damage in children.
Kogenate FS is not used to treat von Willebrand's Disease.
Who should not use Kogenate FS?
You should not use Kogenate FS if you
- are allergic to rodents (like mice and hamsters).
- are allergic to any ingredients in Kogenate FS.
Tell your healthcare provider if you are pregnant or breast-feeding because Kogenate FS may not be right for you.
What should I tell my healthcare provider before I use Kogenate FS?
Tell your healthcare provider about all of your medical conditions.
Tell your healthcare provider and pharmacist about all of the medicines you take, including all prescription and non-prescription medicines, such as over-the-counter medicines, supplements, or herbal remedies.
Tell your healthcare provider if you have been told that you have inhibitors to factor VIII (because Kogenate FS may not work for you).
What are the possible side effects of Kogenate FS?
You could have an allergic reaction to Kogenate FS. Call your healthcare provider right away and stop treatment if you get
- rash or hives
- itching
- tightness of the chest or throat
- difficulty breathing
- light-headed, dizziness
- nausea
- decrease in blood pressure
Your body can also make antibodies, called “inhibitors,” against Kogenate FS, which may stop Kogenate FS from working properly. Consult with your healthcare provider to make sure you are carefully monitored with blood tests for the development of inhibitors to factor VIII.
Other common side effects of Kogenate FS are
- Local injection site reactions (pain, swelling, irritation at infusion site)
- Infections from implanted injection device
Tell your healthcare provider about any side effect that bothers you or does not go away.
Finding veins for injections may be difficult in young children. When frequent injections are required your child's healthcare provider may propose to have a device surgically placed under the skin to facilitate access to the bloodstream. These devices may result in infections.
These are not all the possible side effects with Kogenate FS. You can ask your healthcare provider for information that is written for healthcare professionals.
How do I store Kogenate FS?
Do not freeze Kogenate FS.
Kogenate FS vials containing powdered product (without sterile diluent added) should be stored in a refrigerator (2°C–8°C [36°F–46°F]), or at room temperature (up to 25°C or 77°F) for up to 3 months.
If you choose to store Kogenate FS at room temperature, be sure to note on the carton the date that the product is removed from refrigeration. Store vials in their original carton and protect them from extreme exposure to light.
Reconstituted product (after mixing dry products with wet diluent) must be used within 3 hours and cannot be stored.
Throw away any unused Kogenate FS after the expiration date.
Do not use reconstituted Kogenate FS if it is not clear to slightly cloudy and colorless.
What else should I know about Kogenate FS and hemophilia A?
Medicines are sometimes prescribed for purposes other than those listed here. Do not use Kogenate FS for a condition for which it is not prescribed. Do not share Kogenate FS with other people, even if they have the same symptoms that you have.
This leaflet summarizes the most important information about Kogenate FS. If you would like more information, talk to your healthcare provider. You can ask your healthcare provider or pharmacist for information about Kogenate FS that was written for healthcare professionals.
Instructions for use
How should I take Kogenate FS?
Do not attempt to self-infuse unless you have been taught how by your healthcare provider or hemophilia center.
See the step-by-step instructions for reconstituting Kogenate FS with BIO-SET at the end of this leaflet and the specific infusion instruction leaflet provided.
You should always follow the specific instructions given by your healthcare provider. The steps listed below are general guidelines for using Kogenate FS. If you are unsure of the procedures, please call your healthcare provider before using.
Call your healthcare provider right away if bleeding is not controlled after using Kogenate FS.
Your healthcare provider will prescribe the dose that you should take.
Your healthcare provider may need to take blood tests from time to time.
Talk to your healthcare provider before traveling. You should plan to bring enough Kogenate FS for your treatment during this time.
Carefully handle Kogenate FS. Dispose of all materials, including any leftover reconstituted Kogenate FS product, in an appropriate container.
Reconstitution and use of Kogenate FS
Always work on a clean surface and wash your hands before performing the following procedures:
1. Prepare
A. Open
The easiest way to remove the cap from the vials is to move the top from side-to-side while pulling upward at the same time. This breaks the small plastic tabs that connect the cap to the top of the vial.
B. Remove Tip Cap
Remove the tamper-evident tip cap from the syringe. Separate the tip cap from the syringe by gently breaking it off. Hold the syringe in one hand while snapping off the tip cap with the other hand. Do not try to twist it off. Move it from side to side.
C. Connect Syringe
Connect the prefilled syringe to the powder vial by gently screwing it on clockwise on to the top of the vial until finger tight. Do not overtighten.
2. Activate
A. Activate (Spike the vial)
Place the vial on a solid, non-skid surface. Hold the vial firmly with one hand. With the other hand, place your thumb and forefinger on the fingerplate of the syringe and press down firmly on the fingerplate until it meets the top of the powder vial. This is the most critical step in the process. If the syringe is not pushed down firmly enough, the system will not be fully activated.
B. Connect Plunger Rod
Grasp the plunger rod at the top. Avoid contact with the rest of the plunger rod. Immediately connect it to the syringe by screwing the plunger rod clockwise into the rubber stopper.
C. Inject
Inject diluent into the vial by slowly pressing down the plunger rod. Pushing down the syringe too quickly may cause foaming in the vial. If this occurs, wait until the foam subsides before continuing.
D. Mix
Mix the diluent and powder by swirling gently and slowly. DO NOT SHAKE THE VIAL. Be sure the powder is completely dissolved before using.
3. Transfer
A. Transfer
Invert the vial, with the syringe still attached and smoothly draw all the solution into the syringe. Tilt the vial to the side and back to check that all remaining solution has been drawn into the large opening in the rubber stopper.
B. Disconnect
Disconnect the syringe from the empty vial by unscrewing it counterclockwise. DO NOT PULL THE SYRINGE FROM THE VIAL WITHOUT UNSCREWING IT FIRST.
C. Infuse
Attach the syringe to the butterfly set by screwing it in clockwise and follow the infusion instructions provided with Kogenate FS with BIO-SET.
Rate of administration
The entire dose of Kogenate FS can usually be infused within 1 to 15 minutes. However, your healthcare provider will determine the rate of administration that is best for you.
