( 2.2 ) Patients weighing less than 50 kg: 150 mcg administered as a single spray ( 2.2 ) Should not be used in infants younger than 11 months. ( 2.2 ) Not indicated for patients who require less than a 150 mcg dose. ( 2.2 ) 2.1 Pretreatment Testing and On-Treatment Monitoring Hemophilia A Laboratory tests for assessing patient status include levels of Factor VIII coagulant, Factor VIII antigen and Factor VIII ristocetin cofactor (von Willebrand factor) as well as activated partial thromboplastin time. Factor VIII coagulant activity should be determined before giving STIMATE for hemostasis. If Factor VIII coagulant activity is present at less than 5% of normal, STIMATE should not be relied on. von Willebrand's Disease Laboratory tests for assessing patient status include levels of Factor VIII coagulant activity, VWF:RCo and VWF:Ag. Fluid Restriction Instruct patients about appropriate fluid restriction during STIMATE treatment. Fluid restriction should be observed, and fluid intake should be limited to a minimum, from 1 hour before desmopressin administration, until at least 24 hours after administration [see Warnings and Precautions ( 5.1 )]. 2.2 Recommended Dosage The recommended dosage for patients weighing at least 50 kg is 300 mcg intranasal spray (one spray in each nostril). The recommended dosage for patients weighing less than 50 kg is 150 mcg administered as a single intranasal spray. The use of STIMATE is not indicated for patients who require less than a 150 mcg dose or doses that are not multiples of 150 mcg because the spray pump can only deliver doses of 150 mcg [see Indications and Usage ( 1 )] . If other doses are required, DDAVP Injection may be used [see Warnings and Precautions ( 2.3 )] . If STIMATE is used preoperatively, it should be administered 2 hours prior to the scheduled procedure. The necessity for repeat administration of STIMATE or use of any blood products for hemostasis should be determined by laboratory response as well as the clinical condition of the patient. The tendency toward tachyphylaxis (lessening of response) with repeated administration given more frequently than once every 48 hours should be considered in treating each patient. Must prime the spray pump prior to the first use. Instruct patients to: Prime STIMATE before initial use by releasing 6 sprays or until a fine mist appears. When STIMATE has not been used within 3 days, re-prime the pump by pressing down on the pump twice, or until you see a fine mist. Discard STIMATE 6 months after it is opened, after 25 sprays, or by the expiration date, whichever is sooner. Pediatric Patients STIMATE should not be used in infants younger than 11 months in the treatment of hemophilia A or von Willebrand’s disease. Use in infants and children will require careful fluid intake restriction to prevent possible hyponatremia and water intoxication [see Warnings and Precautions ( 5.1 )] . 2.3 Switching Between Desmopressin Acetate Formulations Desmopressin acetate, for hemostatic use or therapeutic control of bleeding in patients with hemophilia A and mild to moderate von Willebrand’s disease (Type I), is also available as a solution for injection (DDAVP Injection). For surgical procedures, parenteral administration of desmopressin is primarily recommended. In situations where the intranasal route may be compromised, parenteral administration of desmopressin should be considered [see Warnings and Precautions ( 5.3 )] .

( 5.1 ) Hypotension and Hypertension : May cause hypotension with compensatory increase in heart rate or hypertension. Monitor blood pressure during STIMATE administration, especially in patients with heart disease. ( 5.2 ) Altered Absorption in Patients with Nasal Mucosa Abnormalities: changes in the nasal mucosa such as scarring, edema, or other disease may cause erratic, unreliable absorption. ( 5.3 ) Hypersensitivity Reactions : Severe reactions have occurred. Monitor for reactions during administration and interrupt if reaction occurs. ( 5.4 ) Increased Risk of Thrombosis in Patients with von Willebrand’s Disease Type IIB : Use of STIMATE in patients with Type IIB von Willebrand’s disease may cause thrombosis due to platelet aggregation. ( 5.5 ) 5.1 Hyponatremia Serious and fatal hyponatremia may occur with STIMATE use. STIMATE is contraindicated in patients with hyponatremia (or a history of it) and known or suspected syndrome of inappropriate antidiuretic hormone (SIADH) secretion [see Contraindications ( 4 )] . Excessive fluid intake when urine output is limited by the antidiuretic effect of desmopressin may lead to water intoxication with hyponatremia. Cases of hyponatremia have been reported from post-marketing experience in patients treated with desmopressin acetate. Unless properly diagnosed and treated, hyponatremia can be fatal. Observe patients receiving STIMATE for the following signs or symptoms associated with hyponatremia: headache, nausea/vomiting, decreased serum sodium, weight gain, restlessness, malaise, fatigue, lethargy, disorientation, depressed reflexes, loss appetite, irritability, muscle weakness, muscle spasms or cramps, and abnormal mental status such as hallucinations, decreased consciousness, and confusion. Severe symptoms due to an extreme decrease in serum sodium and plasma osmolality may include one or a combination of the following: seizure, coma, and/or respiratory arrest. Advise patients to restrict fluids in order to decrease the risk of water intoxication with hyponatremia. Careful fluid intake restriction is particularly important in pediatric and geriatric patients because these patients are at greater risk of developing hyponatremia [see Use in Specific Populations ( 8.4 , 8.5 )]. More frequent monitoring of serum sodium levels is recommended in the following patients: those with conditions associated with fluid and electrolyte imbalance, such as cystic fibrosis, heart failure, renal disorders, habitual or psychogenic polydipsia or those taking concomitant drugs that may cause hyponatremia or are known to induce SIADH . 5. 2 Hypotension and Hypertension STIMATE may cause changes in blood pressure. Changes have included elevation or reduction in blood pressure which may also cause a compensatory increase in heart rate. Monitor blood pressure and pulse more frequently if used in patients with coronary artery insufficiency and/or hypertensive cardiovascular disease. 5. 3 Altered Absorption in Patients with Nasal Mucosa Abnormalities Since STIMATE is used intranasally, changes in the nasal mucosa such as scarring, edema, or other disease may cause erratic, unreliable absorption in which case STIMATE should be discontinued until the nasal problems resolve. Avoid use of STIMATE in such patients and consider use of other formulations of desmopressin acetate given by other routes of administration [see Dosage and Administration ( 2.4 )] . 5.4 Hypersensitivity Reactions STIMATE is contraindicated in patients with known hypersensitivity to desmopressin acetate or to any of the components of STIMATE [see Contraindications ( 4 )] . Severe allergic reactions, including fatal anaphylaxis, have been reported with desmopressin. It is not known whether antibodies to desmopressin acetate are produced after repeated administration. 5.5 Increased Risk of Thrombosis in Patients with von Willebrand’s Disease Type IIB STIMATE is contraindicated in patients with Type IIB von Willebrand's disease [see Contraindications ( 4 )] .

There are risks associated with untreated hemophilia A and von Willebrand’s disease during pregnancy (see Clinical Considerations). In vitro studies with human placenta demonstrate poor placental transfer of desmopressin. No adverse developmental outcomes were observed in animal reproduction studies with administration of desmopressin during organogenesis to pregnant rats and rabbits at doses approximately <1 and 38 times, respectively, the maximum recommended human dose based on body surface area (mg/m 2 ) (see Data). The background risk of major birth defects and miscarriage for the indicated population are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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. Clinical Considerations Disease Associated Maternal and Embryo-fetal Risk Pregnant women with Hemophilia A or von Willebrand’s disease may be at an increased risk for bleeding diatheses and hemorrhagic events at delivery. A newborn born to a mother with Hemophilia A or von Willebrand disease may also be at risk for bleeding diatheses. Data Animal Data Desmopressin acetate at up to 50 ng/kg/day was given by subcutaneous injection to pregnant rats, from gestation day 1 to 20 during the period of early embryonic development and organogenesis without teratogenic effects. Desmopressin acetate at up to 10 mcg/kg/day was given to pregnant rabbits by subcutaneous injection from gestation day 6 to 18 during fetal organogenesis without teratogenic effects. These doses of desmopressin acetate represent approximately <1 times (rat) and 38 times (rabbit) the maximum recommended human dose based on body surface area (mg/m 2 ). 8.2 Lactation Risk Summary Breastfeeding is not expected to result in clinically relevant exposure of the infant to desmopressin following maternal intranasal administration. Desmopressin is transferred into human breastmilk at negligible amounts (see Data). There is no information on the effects of desmopressin on the breastfed infant or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for STIMATE and any potential adverse effects on the breastfed infant from STIMATE or from the underlying maternal condition. Data A trial was conducted in six healthy lactating women, at greater than 4 months postpartum, to evaluate intranasal administration of 300 mcg single dose of desmopressin acetate. Samples of maternal plasma and breastmilk were obtained at 0, 30, 60, 120, 240, 360 and 480 min after the drug administration. At 8 hours after dose intake, the levels in the milk ranged between 4.16 and 101 pg/ml, and the plasma levels ranged between 40 and 242 pg/ml. The total amount of desmopressin present in the milk over the 8 hours ranged between 491 pg and 16 ng, which corresponds to 0.0001 - 0.005% of the administered dose to the breastfeeding mother. 8.4 Pediatric Use The safety and effectiveness of STIMATE has been established in children between 11 months and 12 years with hemophilia A or von Willebrand’s disease. Use in infants and pediatric patients will require careful fluid intake restriction to prevent possible hyponatremia and water intoxication. Fluid restriction should be discussed with the patient and/or guardian [see Warnings and Precautions ( 5.1 )]. The safety and effectiveness of STIMATE have not been established in pediatric patients younger than 11 months old. 8.5 Geriatric Use Clinical studies of STIMATE did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at a low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy. Because elderly patients are more likely to have renal impairment, care should be taken in dose selection, and monitoring renal function is recommended .

The increase reaches a maximum at about 1.5 hours. The percentage increase of Factor VIII and von Willebrand factor levels in patients with mild hemophilia A and von Willebrand's disease was not notably different from that observed in normal healthy individuals when treated with 300 mcg of STIMATE. In patients with von Willebrand's disease, levels of Factor VIII coagulant activity and von Willebrand factor antigen remained greater than 30 U/dL for 8 hours after a 300 mcg dose of STIMATE. After 300 mcg of STIMATE, the percentage increase of Factor VIII and von Willebrand factor levels in patients with mild hemophilia A and von Willebrand's disease was less than observed after 0.3 mcg/kg of intravenous desmopressin acetate. 12.3 Pharmacokinetics Absorption Plasma concentrations of desmopressin acetate following administration of STIMATE were maximal approximately 40 to 45 minutes after dosing. The absolute bioavailability of STIMATE administered by the intranasal route as a 1.5 mg/mL solution is between 3.3 and 4.1 percent.
