Latisse





Dosage Form: ophthalmic solution
FULL PRESCRIBING INFORMATION

Indications and Usage for Latisse


Latisse® (bimatoprost ophthalmic solution) 0.03% is indicated to treat hypotrichosis of the eyelashes by increasing their growth including length, thickness and darkness.



Latisse Dosage and Administration


Ensure the face is clean, makeup and contact lenses are removed. Once nightly, place one drop of Latisse® (bimatoprost ophthalmic solution) 0.03% on the disposable sterile applicator supplied with the package and apply evenly along the skin of the upper eyelid margin at the base of the eyelashes. The upper lid margin in the area of lash growth should feel lightly moist without runoff. Blot any excess solution runoff outside the upper eyelid margin with a tissue or other absorbent cloth. Dispose of the applicator after one use. Repeat for the opposite eyelid margin using a new sterile applicator.


Do not reuse applicators and do not use any other brush/applicator to apply Latisse®.


Do not apply to the lower eyelash line (see WARNINGS AND PRECAUTIONS, 5.3, 5.4, and PATIENT COUNSELING INFORMATION, 17.1).


Additional applications of Latisse® will not increase the growth of eyelashes.


Upon discontinuation of treatment, eyelash growth is expected to return to its pre-treatment level.



Dosage Forms and Strengths


Bimatoprost ophthalmic solution 0.3 mg/mL.



Contraindications


None



Warnings and Precautions



Effects on Intraocular Pressure


Bimatoprost ophthalmic solution (LUMIGAN®) lowers intraocular pressure (IOP) when instilled directly to the eye in patients with elevated IOP. In clinical trials, in patients with or without elevated IOP, Latisse® lowered IOP, however, the magnitude of the reduction was not cause for clinical concern.


In ocular hypertension studies with LUMIGAN®, it has been shown that exposure of the eye to more than one dose of bimatoprost daily may decrease the intraocular pressure lowering effect. In patients using LUMIGAN® or other prostaglandin analogs for the treatment of elevated intraocular pressure, the concomitant use of Latisse® may interfere with the desired reduction in IOP. Patients using prostaglandin analogs including LUMIGAN® for IOP reduction should only use Latisse® after consulting with their physician and should be monitored for changes to their intraocular pressure (see PATIENT COUNSELING INFORMATION, 17.3).



Iris Pigmentation


Increased iris pigmentation has occurred when bimatoprost solution was administered. Patients should be advised about the potential for increased brown iris pigmentation which is likely to be permanent (see ADVERSE REACTIONS, 6.2 and PATIENT COUNSELING INFORMATION, 17.5).


The pigmentation change is due to increased melanin content in the melanocytes rather than to an increase in the number of melanocytes. The long term effects of increased pigmentation are not known. Iris color changes seen with administration of bimatoprost ophthalmic solution may not be noticeable for several months to years. Typically, the brown pigmentation around the pupil spreads concentrically towards the periphery of the iris and the entire iris or parts of the iris become more brownish. Neither nevi nor freckles of the iris appear to be affected by treatment. Treatment with Latisse® solution can be continued in patients who develop noticeably increased iris pigmentation.



Lid Pigmentation


Bimatoprost has been reported to cause pigment changes (darkening) to periorbital pigmented tissues and eyelashes. The pigmentation is expected to increase as long as bimatoprost is administered, but has been reported to be reversible upon discontinuation of bimatoprost in most patients (see PATIENT COUNSELING INFORMATION, 17.4).



Hair Growth Outside the Treatment Area


There is the potential for hair growth to occur in areas where Latisse® solution comes in repeated contact with the skin surface. It is important to apply Latisse® only to the skin of the upper eyelid margin at the base of the eyelashes using the accompanying sterile applicators, and to carefully blot any excess Latisse® from the eyelid margin to avoid it running onto the cheek or other skin areas (see PATIENT COUNSELING INFORMATION, 17.6).



Intraocular Inflammation


Latisse® solution should be used with caution in patients with active intraocular inflammation (e.g., uveitis) because the inflammation may be exacerbated.



Macular Edema


Macular edema, including cystoid macular edema, has been reported during treatment with bimatoprost ophthalmic solution (LUMIGAN®) for elevated IOP. Latisse® should be used with caution in aphakic patients, in pseudophakic patients with a torn posterior lens capsule, or in patients with known risk factors for macular edema.



Contamination of Latisse® or Applicators


The Latisse® bottle must be kept intact during use. It is important to use Latisse® solution as instructed, by placing one drop on the single-use-per-eye applicator. The bottle tip should not be allowed to contact any other surface since it could become contaminated. The accompanying sterile applicators should only be used on one eye and then discarded since reuse of applicators increases the potential for contamination and infections. There have been reports of bacterial keratitis associated with the use of multiple-dose containers of topical ophthalmic products (see PATIENT COUNSELING INFORMATION, 17.2).



Use with Contact Lenses


Latisse® contains benzalkonium chloride, which may be absorbed by soft contact lenses. Contact lenses should be removed prior to application of solution and may be reinserted 15 minutes following its administration (see PATIENT COUNSELING INFORMATION, 17.8).



Adverse Reactions



Clinical Studies Experience


The following information is based on clinical trial results from a multicenter, double-masked, randomized, vehicle-controlled, parallel study including 278 adult patients for four months of treatment.


The most frequently reported adverse events were eye pruritus, conjunctival hyperemia, skin hyperpigmentation, ocular irritation, dry eye symptoms, and erythema of the eyelid. These events occurred in less than 4% of patients.


Adverse reactions reported with bimatoprost ophthalmic solution (LUMIGAN®) for the reduction of intraocular pressure include, ocular dryness, visual disturbance, ocular burning, foreign body sensation, eye pain, blepharitis, cataract, superficial punctate keratitis, eye discharge, tearing, photophobia, allergic conjunctivitis, asthenopia, increases in iris pigmentation, conjunctival edema, abnormal hair growth, iritis, infections (primarily colds and upper respiratory tract infections), headaches, and asthenia.



Postmarketing Experience


The following reactions have been identified during postmarketing use of Latisse® in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. The reactions, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to Latisse®, or a combination of these factors, include: burning sensation (eyelid), erythema periorbital, eye swelling, eyelid irritation, eyelid edema, eyelids pruritus, iris hyperpigmentation, lacrimation increased, madarosis and trichorrhexis (temporary loss of a few eyelashes to loss of sections of eyelashes, and temporary eyelash breakage, respectively), periorbital and lid changes associated with a deepening of the eyelid sulcus, rash (including macular, erythematous, and pruritic limited to the eyelids and periorbital region), skin discoloration (periorbital), and vision blurred.



USE IN SPECIFIC POPULATIONS



Pregnancy


Pregnancy Category C



Teratogenic effects: In embryo/fetal developmental studies in pregnant mice and rats, abortion was observed at oral doses of bimatoprost which achieved at least 33 or 97 times, respectively, the maximum intended human exposure (based on blood AUC levels after topical ophthalmic administration to the cornea or conjunctival sac).


At doses at least 41 times the maximum intended human exposure, the gestation length was reduced in the dams, the incidence of dead fetuses, late resorptions, peri- and postnatal pup mortality was increased, and pup body weights were reduced.


There are no adequate and well-controlled studies of bimatoprost ophthalmic solution 0.03% administration in pregnant women. Because animal reproductive studies are not always predictive of human response, Latisse® should be administered during pregnancy only if the potential benefit justifies the potential risk to the fetus.



Nursing Mothers


It is not known whether Latisse® solution is excreted in human milk, although in animal studies, bimatoprost has been shown to be excreted in breast milk. Because many drugs are excreted in human milk, caution should be exercised when Latisse® is administered to a nursing woman.



Pediatric Use


Safety and effectiveness in pediatric patients have not been established.



Geriatric Use


No overall clinical differences in safety or effectiveness have been observed between elderly and other adult patients.



Latisse Description


Latisse® (bimatoprost ophthalmic solution) 0.03% is a synthetic prostaglandin analog. Its chemical name is (Z) - 7 - [(1R,2R,3R,5S) - 3,5 - Dihydroxy - 2 - [(1E,3S) - 3 - hydroxy - 5 - phenyl - 1 - pentenyl]cyclopentyl] - N - ethyl - 5 - heptenamide, and its molecular weight is 415.58. Its molecular formula is C25H37NO4. Its chemical structure is:



Bimatoprost is a powder, which is very soluble in ethyl alcohol and methyl alcohol and slightly soluble in water. Latisse® is a clear, isotonic, colorless, sterile ophthalmic solution with an osmolality of approximately 290 mOsmol/kg.


Contains: Active: bimatoprost 0.3 mg/mL; Preservative: benzalkonium chloride 0.05 mg/mL; Inactives: sodium chloride; sodium phosphate, dibasic; citric acid; and purified water. Sodium hydroxide and/or hydrochloric acid may be added to adjust pH. The pH during its shelf life ranges from 6.8 - 7.8.



Latisse - Clinical Pharmacology



Mechanism of Action


Bimatoprost is a structural prostaglandin analog. Although the precise mechanism of action is unknown the growth of eyelashes is believed to occur by increasing the percent of hairs in, and the duration of the anagen or growth phase.



Pharmacokinetics



Absorption


After one drop of bimatoprost ophthalmic solution 0.03% was administered once daily into both eyes (cornea and/or conjunctival sac) of 15 healthy subjects for two weeks, blood concentrations peaked within 10 minutes after dosing and were below the lower limit of detection (0.025 ng/mL) in most subjects within 1.5 hours after dosing. Mean Cmax and AUC0-24hr values were similar on days 7 and 14 at approximately 0.08 ng/mL and 0.09 ng•hr/mL, respectively, indicating that steady state was reached during the first week of ocular dosing. There was no significant systemic drug accumulation over time.



Distribution


Bimatoprost is moderately distributed into body tissues with a steady-state volume of distribution of 0.67 L/kg. In human blood, bimatoprost resides mainly in the plasma. Approximately 12% of bimatoprost remains unbound in human plasma.



Metabolism


Bimatoprost is the major circulating species in the blood once it reaches the systemic circulation. Bimatoprost then undergoes oxidation, N-deethylation, and glucuronidation to form a diverse variety of metabolites.



Elimination


Following an intravenous dose of radiolabeled bimatoprost (3.12 mcg/kg) to six healthy subjects, the maximum blood concentration of unchanged drug was 12.2 ng/mL and decreased rapidly with an elimination half-life of approximately 45 minutes. The total blood clearance of bimatoprost was 1.5 L/hr/kg. Up to 67% of the administered dose was excreted in the urine while 25% of the dose was recovered in the feces.



Nonclinical Toxicology



Carcinogenesis, Mutagenesis, Impairment of Fertility


Bimatoprost was not carcinogenic in either mice or rats when administered by oral gavage at doses of up to 2 mg/kg/day and 1 mg/kg/day respectively (approximately 192 and 291 times the recommended human exposure based on blood AUC levels after topical corneal and/or conjunctival sac administration respectively) for 104 weeks.


Bimatoprost was not mutagenic or clastogenic in the Ames test, in the mouse lymphoma test, or in the in vivo mouse micronucleus tests.


Bimatoprost did not impair fertility in male or female rats up to doses of 0.6 mg/kg/day.



Clinical Studies


Latisse® solution was evaluated for its effect on overall eyelash prominence in a multicenter, double-masked, randomized, vehicle-controlled, parallel study including 278 adult patients for four months of treatment. The primary efficacy endpoint in this study was an increase in overall eyelash prominence as measured by at least a 1-grade increase on the 4-point Global Eyelash Assessment (GEA) scale, from baseline to the end of the treatment period (week 16). Latisse® was more effective than vehicle as measured by the GEA score, with statistically significant differences seen at 8-week, 12-week, and 16-week (primary endpoint) treatment durations.

In this study, patients were also evaluated for the effect of Latisse® solution on the length, thickness and darkness of their eyelashes. Improvements from baseline in eyelash growth as measured by digital image analysis assessing eyelash length, fullness/thickness, and darkness were statistically significantly more pronounced in the bimatoprost group at weeks 8, 12, and 16.

How Supplied/Storage and Handling


Latisse® (bimatoprost ophthalmic solution) 0.03% is supplied sterile in opaque white low density polyethylene dispenser bottles and tips with turquoise polystyrene caps accompanied by 60 sterile, disposable applicators:


3 mL in a 5 mL bottle NDC 0023-3616-03



Storage: Latisse® should be stored at 2° to 25°C (36° to 77°F).



Patient Counseling Information



Nightly Application


Patients should be informed that Latisse® (bimatoprost ophthalmic solution) should be applied every night using only the accompanying sterile applicators. They should start by ensuring their face is clean, all makeup is removed, and their contact lenses removed (if applicable). Then, carefully place one drop of Latisse® solution on the disposable sterile applicator and brush cautiously along the skin of the upper eyelid margin at the base of the eyelashes. If any Latisse® solution gets into the eye proper, it will not cause harm. The eye should not be rinsed.


Additional applications of Latisse® will not increase the growth of eyelashes.


Patients should be informed not to apply to the lower eyelash line. Any excess solution outside the upper eyelid margin should be blotted with a tissue or other absorbent material.


The onset of effect is gradual but is not significant in the majority of patients until 2 months. Patients should be counseled that the effect is not permanent and can be expected to gradually return to the original level upon discontinuation of treatment with Latisse®.



Handling the Bottle and Applicator


Patients should be instructed that the Latisse® bottle must be maintained intact and to avoid allowing the tip of the bottle or applicator to contact surrounding structures, fingers, or any other unintended surface in order to avoid contamination of the bottle or applicator by common bacteria known to cause ocular infections. Patients should also be instructed to only use the applicator supplied with the product once and then discard since reuse could result in using a contaminated applicator. Serious infections may result from using contaminated solutions or applicators.



Potential for Intraocular Pressure Effects


Latisse® may lower intraocular pressure although not to a level that will cause clinical harm.


In patients using LUMIGAN® or other prostaglandin analogs for the treatment of elevated intraocular pressure, the concomitant use of Latisse® may interfere with the desired reduction in IOP. Patients using prostaglandin analogs for IOP reduction should only use Latisse® after consulting with their physician.



Potential for Eyelid Skin Darkening


Patients should be informed about the possibility of eyelid skin darkening, which may be reversible after discontinuation of Latisse®.



Potential for Iris Darkening


Patients should be advised about the potential for increased brown iris pigmentation which is likely to be permanent. Increased iris pigmentation has occurred when bimatoprost solution was administered.



Potential for Unexpected Hair Growth or Eyelash Changes


Patients should be informed of the possibility of hair growth occurring outside of the target treatment area if Latisse® repeatedly touches the same area of skin outside the treatment area. They should also be informed of the possibility of disparity between eyes in length, thickness, pigmentation, number of eyelashes or vellus hairs, and/or direction of eyelash growth. Eyelash changes are likely reversible upon discontinuation of treatment.



When to Seek Physician Advice


Patients should be advised that if they develop a new ocular condition (e.g., trauma or infection), experience a sudden decrease in visual acuity, have ocular surgery, or develop any ocular reactions, particularly conjunctivitis and eyelid reactions, they should immediately seek their physician's advice concerning the continued use of Latisse®. Patients on IOP-lowering medications should not use Latisse® without prior consultation with their physician.



Use with Contact Lenses


Patients should be advised that Latisse® solution contains benzalkonium chloride, which may be absorbed by soft contact lenses. Contact lenses should be removed prior to application of Latisse® and may be reinserted 15 minutes following its administration.

FDA-approved Patient Labeling



PATIENT INFORMATION


Latisse® (la teece) (bimatoprost ophthalmic solution) 0.03%


Read the Patient Information that comes with Latisse® before you start using it and each time you get a refill. There may be new information. This leaflet does not take the place of talking with your physician about your treatment.


What is hypotrichosis of the eyelashes?


Hypotrichosis is another name for having inadequate or not enough eyelashes.


What is Latisse® solution?


Latisse® solution is a prescription treatment for hypotrichosis used to grow eyelashes, making them longer, thicker and darker.


Who should NOT take Latisse®?


Do not use Latisse® solution if you are allergic to one of its ingredients.


Are there any special warnings associated with Latisse® use?


Latisse® solution is intended for use on the skin of the upper eyelid margins at the base of the eyelashes. Refer to Illustration 2 below. DO NOT APPLY to the lower eyelid. If you are using LUMIGAN® or other products in the same class for elevated intraocular pressure (IOP), or if you have a history of abnormal IOP, you should only use Latisse® under the close supervision of your physician.


Latisse® use may cause darkening of the eyelid skin which may be reversible. Latisse® use may also cause increased brown pigmentation of the colored part of the eye which is likely to be permanent.


It is possible for hair growth to occur in other areas of your skin that Latisse® frequently touches. Any excess solution outside the upper eyelid margin should be blotted with a tissue or other absorbent material to reduce the chance of this from happening. It is also possible for a difference in eyelash length, thickness, fullness, pigmentation, number of eyelash hairs, and/or direction of eyelash growth to occur between eyes. These differences, should they occur, will usually go away if you stop using Latisse®.


Who should I tell that I am using Latisse®?


You should tell your physician you are using Latisse® especially if you have a history of eye pressure problems.


You should also tell anyone conducting an eye pressure screening that you are using Latisse®.


What should I do if I get Latisse® in my eye?


Latisse® solution is an ophthalmic drug product. Latisse® is not expected to cause harm if it gets into the eye proper. Do not attempt to rinse your eye in this situation.


What are the possible side effects of Latisse®?


The most common side effects after using Latisse® solution are an itching sensation in the eyes and/or eye redness. This was reported in approximately 4% of patients. Latisse® solution may cause other less common side effects which typically occur on the skin close to where Latisse® is applied, or in the eyes. These include skin darkening, eye irritation, dryness of the eyes, and redness of the eyelids.


If you develop a new ocular condition (e.g., trauma or infection), experience a sudden decrease in visual acuity, have ocular surgery, or develop any ocular reactions, particularly conjunctivitis and eyelid reactions, you should immediately seek your physician's advice concerning the continued use of Latisse® solution.


What happens if I stop using Latisse®?


If you stop using Latisse®, your eyelashes are expected to return to their previous appearance over several weeks to months.


Any eyelid skin darkening is expected to reverse after several weeks to months.


Any darkening of the colored part of the eye known as the iris is NOT expected to reverse and is likely permanent.


How do I use Latisse®?


Latisse® solution is packaged as a 3 mL bottle of solution with 60 accompanying sterile, disposable applicators. The recommended dosage is one application nightly to the skin of the upper eyelid margin at the base of the eyelashes only.


Once nightly, start by ensuring your face is clean, makeup and contact lenses are removed. Remove an applicator from its tray. Then, holding the sterile applicator horizontally, place one drop of Latisse® on the area of the applicator closest to the tip but not on the tip (see Illustration 1). Then immediately draw the applicator carefully across the skin of the upper eyelid margin at the base of the eyelashes (where the eyelashes meet the skin) going from the inner part of your lash line to the outer part (see Illustration 2). Blot any excess solution beyond the eyelid margin. Dispose of the applicator after one use.


Repeat for the opposite upper eyelid margin using a new sterile applicator. This helps minimize any potential for contamination from one eyelid to another.

Illustration 2


DO NOT APPLY in your eye or to the lower lid. ONLY use the sterile applicators supplied with Latisse® to apply the product. If you miss a dose, don't try to “catch up.” Just apply Latisse® solution the next evening. Fifty percent of patients treated with Latisse® in a clinical study saw significant improvement by 2 months after starting treatment.


If any Latisse® solution gets into the eye proper, it is not expected to cause harm. The eye should not be rinsed.


Don't allow the tip of the bottle or applicator to contact surrounding structures, fingers, or any other unintended surface in order to avoid contamination by common bacteria known to cause infections.


Contact lenses should be removed prior to application of Latisse® and may be reinserted 15 minutes following its administration.


Use of Latisse® more than once a day will not increase the growth of eyelashes more than use once a day.


Store Latisse® solution at 36° to 77°F (2° to 25°C).

KOGENATE Bayer 3000 IU Powder and solvent for solution for injection.(Medimop)





1. Name Of The Medicinal Product



KOGENATE Bayer 3000 IU powder and solvent for solution for injection.


2. Qualitative And Quantitative Composition



2.1 General description



Each vial contains nominally 3000 IU human coagulation factor VIII (octocog alfa).



Human coagulation factor VIII is produced by recombinant DNA technology (rDNA) in baby hamster kidney cells containing the human factor VIII gene.



2.2 Qualitative and quantitative composition



One ml of KOGENATE Bayer 3000 IU contains approximately 600 IU (3000 IU / 5.0 ml) of human coagulation factor VIII (octocog alfa) after reconstitution.



The potency (IU) is determined using the one-stage clotting assay against the FDA Mega standard which was calibrated against WHO standard in International Units (IU).



The specific activity of KOGENATE Bayer is approximately 4000 IU/mg protein.



Solvent: water for injections.



For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Powder and solvent for solution for injection.



Powder: dry white to slightly yellow powder or cake.



Solvent: water for injection, a clear, colourless solution.



The reconstituted medicinal product is a clear and colourless solution.



4. Clinical Particulars



4.1 Therapeutic Indications



Treatment and prophylaxis of bleeding in patients with haemophilia A (congenital factor VIII deficiency).



This preparation does not contain von Willebrand factor and is therefore not indicated in von Willebrand's disease.



4.2 Posology And Method Of Administration



Treatment should be initiated under the supervision of a physician experienced in the treatment of haemophilia.



Posology



The number of units of factor VIII administered is expressed in International Units (IU), which are related to the current WHO standard for factor VIII products. Factor VIII activity in plasma is expressed either as a percentage (relative to normal human plasma) or in International Units (relative to the International Standard for factor VIII in plasma). One International Unit (IU) of factor VIII activity is equivalent to that quantity of factor VIII in one ml of normal human plasma. The calculation of the required dose of factor VIII is based on the empirical finding that 1 International Unit (IU) factor VIII per kg body weight raises the plasma factor VIII activity by 1.5% to 2.5% of normal activity. The required dose is determined using the following formulae:








I. Required IU = body weight (kg) × desired factor VIII rise (% of normal) × 0.5




 




II. Expected factor VIII rise (% of normal) =




2 × administered IU



body weight (kg)



On demand treatment



The dose, frequency and duration of the substitution therapy must be individualised according to the patient's needs (weight, severity of disorder of the haemostatic function, the site and extent of the bleeding, the presence of inhibitors, and the factor VIII level desired).



The following table provides a guide for factor VIII minimum blood levels. In the case of the haemorrhagic events listed, the factor VIII activity should not fall below the given level (in % of normal) in the corresponding period:






















Degree of haemorrhage/ Type of surgical procedure




Factor VIII level required (%) (IU/dl)




Frequency of doses (hours)/ Duration of therapy (days)




Haemorrhage



Early haemarthrosis, muscle bleed or oral bleed




 



20 - 40




 



Repeat every 12 to 24 hours. At least 1 day, until the bleeding episode as indicated by pain is resolved or healing is achieved.




More extensive haemarthrosis, muscle bleed or haematoma




30 - 60




Repeat infusion every 12 - 24 hours for 3 - 4 days or more until pain and disability are resolved.




Life threatening bleeds such as intracranial bleed, throat bleed, severe abdominal bleed




60 - 100




Repeat infusion every 8 to 24 hours until threat is resolved




Surgery



Minor



including tooth extraction




 



30 - 60




 



Every 24 hours, at least 1 day, until healing is achieved.




Major




80 - 100



(pre- and postoperative)




a) By bolus infusions



Repeat infusion every 8 - 24 hours until adequate wound healing occurs, then continue with therapy for at least another 7 days to maintain a factor VIII activity of 30% to 60%



b) By continuous infusion



Raise factor VIII activity pre-surgery with an initial bolus infusion and immediately follow with continuous infusion (in IU/Kg/h) adjusting according to patient's daily clearance and desired factor VIII levels for at least 7 days.



The amount to be administered and the frequency of administration should always be adapted according to the clinical effectiveness in the individual case. Under certain circumstances larger amounts than those calculated may be required, especially in the case of the initial dose.



During the course of treatment, appropriate determination of factor VIII levels is advised in order to guide the dose to be administered and the frequency at which to repeat the infusions. In the case of major surgical interventions in particular, precise monitoring of the substitution therapy by means of coagulation analysis (plasma factor VIII activity) is indispensable. Individual patients may vary in their response to factor VIII, achieving different levels of in vivo recovery and demonstrating different half-lives.



Continuous Infusion



It has been shown in a clinical study performed with adult haemophilia A patients who undergo a major surgery that KOGENATE Bayer can be used for continuous infusion in surgeries (pre-, during and postoperative). In this study heparin was used to prevent thrombophlebitis at the infusion site as with any other long term intravenous infusions. For the calculation of the initial infusion rate, clearance can be obtained by performing a pre-surgery decay curve, or by starting from an average population value (3.0-3.5 ml/h/kg) and then adjust accordingly.



Infusion rate (in IU/kg/h) = Clearance (in ml/h/kg) × desired factor VIII level (in IU/ml)



For continuous infusion, clinical and in vitro stability has been demonstrated using ambulatory pumps with a PVC reservoir. KOGENATE Bayer contains low level of polysorbate-80 as an excipient, which is known to increase the rate of di-(2-ethylhexyl)phthalate (DEHP) extraction from polyvinyl chloride (PVC) materials. This should be considered for a continuous infusion administration.



Prophylaxis



For long term prophylaxis against bleeding in patients with severe haemophilia A, the usual doses are 20 to 40 IU of KOGENATE Bayer per kg body weight at intervals of 2 to 3 days.



In some cases, especially in younger patients, shorter dose intervals or higher doses may be necessary.



Paediatric population



Data have been obtained from clinical studies in 61 children under 6 years of age and non-interventional studies in children of all ages.



Patients with inhibitors



Patients should be monitored for the development of factor VIII inhibitors. If the expected plasma factor VIII activity levels are not attained, or if bleeding is not controlled with an appropriate dose, an assay should be performed to determine if a factor VIII inhibitor is present. If the inhibitor is present at levels less than 10 Bethesda Units (BU) per ml, administration of additional recombinant coagulation factor VIII may neutralise the inhibitor and permit continued clinically effective therapy with KOGENATE Bayer. However, in the presence of an inhibitor the doses required are variable and must be adjusted according to clinical response and monitoring of plasma factor VIII activity. In patients with inhibitor titres above 10 BU or with high anamnestic response, the use of (activated) prothrombin complex concentrate (PCC) or recombinant activated factor VII (rFVIIa) preparations has to be considered. These therapies should be directed by physicians with experience in the care of patients with haemophilia.



Method of administration



For intravenous use.



KOGENATE Bayer should be injected intravenously over several minutes. The rate of administration should be determined by the patient's comfort level (maximal rate of infusion: 2 ml/min).



Continuous infusion



KOGENATE Bayer can be infused by continuous infusion. The infusion rate should be calculated based on the clearance and the desired FVIII level.



Example: for a 75 kg patient with a clearance of 3 ml/h/kg, the initial infusion rate would be 3 IU/h/kg to achieve a FVIII level of 100%. For calculation of ml/hour, multiply infusion rate in IU/h/kg by kg bw/concentration of solution (IU/ml).

Higher infusion rates may be required in conditions with accelerated clearance during major bleedings or extensive tissue damage during surgical interventions.



After the initial 24 hours of continuous infusion, the clearance should be recalculated every day using the steady state equation with the measured FVIII level and the rate of infusion using the following equation:



clearance = infusion rate/actual FVIII level.



During continuous infusion, infusion bags should be changed every 24 hours.



For instructions on reconstitution of the medicinal product before administration, see section 6.6 and the package leaflet.

Patients should be made aware that the potential occurrence of chest tightness, dizziness, mild hypotension and nausea during infusion can constitute an early warning for hypersensitivity and anaphylactic reactions. Symptomatic treatment and therapy for hypersensitivity should be instituted as appropriate. If allergic or anaphylactic reactions occur, the injection/infusion should be stopped immediately and patient should contact their physician. In case of shock, the current medical standards for shock treatment should be observed.



Antibodies (inhibitors)



The formation of neutralising antibodies (inhibitors) to factor VIII is a known complication in the management of individuals with haemophilia A. These inhibitors are usually IgG immunoglobulins directed against the factor VIII procoagulant activity, which are quantified in Modified Bethesda Units (BU) per ml of plasma. The risk of developing inhibitors is correlated to the exposure to anti-haemophilic factor VIII and to genetic factors among others, this risk being highest within the first 20 exposure days. Rarely, inhibitors may develop after the first 100 exposure days.



Cases of recurrence of inhibitors (low titre) have been observed after switching from one recombinant factor VIII product to another in previously treated patients with more than 100 exposure days who have a history of inhibitor development.



Patients treated with recombinant coagulation factor VIII should be carefully monitored for the development of inhibitors by appropriate clinical observations and laboratory tests. (See also section 4.8)



Continuous infusion



In a clinical study about the use of continuous infusion in surgeries, heparin was used to prevent thrombophlebitis at the infusion site as with any other long term intravenous infusions.



Registration



In the interest of the patients, it is recommended that, whenever possible, every time that KOGENATE Bayer is administered to them, the name and the batch number of the product is registered.



Sodium content



This medicinal product contains less than 1 mmol sodium (23 mg) per vial, i.e. essentially “sodium free”.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



No interactions of KOGENATE Bayer with other medicinal products are known.



4.6 Pregnancy And Lactation



Animal reproduction studies have not been conducted with KOGENATE Bayer.



Based on the rare occurrence of haemophilia A in women, experience regarding the use of KOGENATE Bayer during pregnancy and breast-feeding is not available. Therefore, KOGENATE Bayer should be used during pregnancy and breast-feeding only if clearly indicated.



There are no fertility data available.



4.7 Effects On Ability To Drive And Use Machines



KOGENATE Bayer has no influence on the ability to drive or to use machines.



4.8 Undesirable Effects



The most commonly reported adverse drug reaction occurring is the formation of neutralising antibodies (prevalent in previously untreated or minimally treated patients).



The frequencies of adverse reactions reported with KOGENATE Bayer are summarized in the table below. Within each frequency group, undesirable effects are presented in order of decreasing seriousness. Frequencies are defined as common (

Description of selected adverse reactions



The formation of neutralising antibodies to factor VIII (inhibitors) is a known complication in the management of individuals with haemophilia A. In studies with recombinant factor VIII preparations, development of inhibitors is predominantly observed in previously untreated haemophiliacs. Patients should be carefully monitored for the development of inhibitors by appropriate clinical observations and laboratory tests.



In clinical studies, KOGENATE Bayer has been used in the treatment of bleeding episodes in 37 previously untreated patients (PUPs) and 23 minimally treated pediatric patients (MTPs, defined as having equal to or less than 4 exposure days). Five out of 37 (14%) PUP and 4 out of 23 (17%) MTP patients treated with KOGENATE Bayer developed inhibitors: Overall, 9 out of 60 (15%) developed inhibitors, 6 out of 60 (10%) with a titre above 10 BU and 3 out of 60 (5%) with a titre below 10 BU. The median number of exposure days at the time of inhibitor detection in these patients was 9 days (range 3 - 18 days).



The median number of exposure days in the clinical studies was 114 (range: 4-478). Four of the five patients, who had not achieved 20 exposure days at the end of the study, ultimately achieved more than 20 exposure days in post-study follow-up and one of them developed a low titre inhibitor. The fifth patient was lost to follow-up.



In clinical studies with 73 previously treated patients (PTP, defined as having more than 100 exposure days), followed over four years, no de-novo inhibitors were observed.



In extensive post-registration studies with KOGENATE Bayer, involving more than 1000 patients the following was observed: Less than 0.2% PTP developed de-novo inhibitors. In a subset defined as having less than 20 exposure days at study entry, less than 11% developed de-novo inhibitors.



During studies, no patient developed clinically relevant antibody titres against the trace amounts of mouse protein and hamster protein present in the preparation. However, the possibility of allergic reactions to constituents, e.g. trace amounts of mouse and hamster protein in the preparation exists in certain predisposed patients (see sections 4.3 and 4.4).



4.9 Overdose



No case of overdose with recombinant coagulation factor VIII has been reported.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: antihemorrhagics: blood coagulation factor VIII, ATC code B02BD02.



The factor VIII/von Willebrand factor (vWF) complex consists of two molecules (factor VIII and vWF) with different physiological functions. When infused into a haemophilic patient, factor VIII binds to vWF in the patient's circulation. Activated factor VIII acts as a cofactor for activated factor IX, accelerating the conversion of factor X to activated factor X. Activated factor X converts prothrombin into thrombin. Thrombin then converts fibrinogen into fibrin and a clot can be formed. Haemophilia A is a sex-linked hereditary disorder of blood coagulation due to decreased levels of factor VIII:C and results in profuse bleeding into joints, muscles or internal organs, either spontaneously or as a result of accidental or surgical trauma. By replacement therapy the plasma levels of factor VIII are increased, thereby enabling a temporary correction of the factor deficiency and correction of the bleeding tendencies.



Determination of activated partial thromboplastin time (aPTT) is a conventional in vitro assay method for biological activity of factor VIII. The aPTT is prolonged in all haemophiliacs. The degree and duration of aPTT normalisation observed after administration of KOGENATE Bayer is similar to that achieved with plasma-derived factor VIII.



5.2 Pharmacokinetic Properties



The analysis of all recorded in vivo recoveries in previously treated patients demonstrated a mean rise of 2 % per IU/kg body weight for KOGENATE Bayer. This result is similar to the reported values for factor VIII derived from human plasma.



After administration of KOGENATE Bayer, peak factor VIII activity decreased by a two-phase exponential decay with a mean terminal half-life of about 15 hours. This is similar to that of plasma-derived factor VIII which has a mean terminal half-life of approx. 13 hours. Additional pharmacokinetic parameters for KOGENATE Bayer for bolus injection are: mean residence time [MRT (0-48)] of about 22 hours and clearance of about 160 ml/h. Mean baseline clearance for 14 adult patients undergoing major surgeries with continuous infusion are 188 ml/h corresponding to 3.0 ml/h/kg (range 1.6-4.6 ml/h/kg).



5.3 Preclinical Safety Data



Even doses several fold higher than the recommended clinical dose (related to body weight) failed to demonstrate any acute or subacute toxic effects for KOGENATE Bayer in laboratory animals (mouse, rat, rabbit, and dog).



Specific studies with repeated administration such as reproduction toxicity, chronic toxicity, and carcinogenicity were not performed with octocog alfa due to the immune response to heterologous proteins in all non-human mammalian species.



No studies were performed on the mutagenic potential of KOGENATE Bayer, since no mutagenic potential could be detected in vitro or in vivo for the predecessor product of KOGENATE Bayer.
