Kinevac Drug Information

The following clinically significant adverse reactions are described elsewhere in labeling: Anaphylaxis, anaphylactic shock, and other serious hypersensitivity reactions Evacuation of gallstones Adverse reactions with intravenous injection Preterm labor or spontaneous abortion The following adverse reactions associated with the use of Kinevac were identified in clinical trials or postmarketing reports. Because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency, reliably, or to establish a causal relationship to drug exposure. The most frequent adverse reactions (20% or greater) are gastrointestinal: abdominal discomfort or pain, and nausea; these may not necessarily indicate an abnormality of the biliary tract unless there is other clinical or radiologic evidence of disease.

Less common adverse reactions include: Hypersensitivity reactions : anaphylaxis and anaphylactic shock, hypotension, throat tightness, bradycardia, shortness of breath, nausea, abdominal cramping, diaphoresis, hives, rash, itching; and numbness of face, lips and eyes . Neurological reactions : seizures, headache. Vasovagal reactions : dizziness, loss of consciousness, nausea, diaphoresis, syncope and hypotension (generally self-limiting). Other: nausea, vomiting, flushing, hypertension, urge to defecate, diarrhea, sneezing. Most common adverse reactions (≥20%) are: abdominal discomfort or pain, and nausea.

Drugs that Affect Gallbladder Motility or Contractile Response Drugs that may stimulate

or inhibit gallbladder motility or contractile response may interfere with the response to sincalide. Consider discontinuing these drugs prior to administration of Kinevac, when used to stimulate contraction of the gallbladder.

Pregnancy Risk Summary Based on limited human data and mechanism of action, sincalide may cause preterm labor or spontaneous abortion. Available data with sincalide for injection are insufficient to establish a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. In animal embryo-fetal development studies in which sincalide was administered to hamsters and rats during the period of organogenesis, no effects were seen at doses comparable to the maximum recommended clinical dose on a mg/kg basis.

However, in a prenatal development study in which rats were administered sincalide during organogenesis through parturition, decreased weight gain and developmental delays were observed at a dose 122 times higher than the maximum recommended human dose based on body surface area. The estimated background risk of major birth defects and miscarriage for the indicated population is 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. Data Animal Data There were no effects on embryo-fetal development in hamsters when sincalide was administered subcutaneously at 250 or 750 ng/kg during organogenesis (Gestation Days 7 to 13) at doses up to 0.8 times the maximum recommended dose of 120 ng/kg on a body surface area basis. No effects on embryo-fetal development were observed in Sprague-Dawley rats at subcutaneous doses of 250, 450, or 750 ng/kg from Gestation Days 6 to16, representing 1.0 time the maximum recommended human dose on a body surface area basis.

In a separate study at a higher dose of 90 mcg/kg administered subcutaneously to CFY rats from Gestation Day 10 through parturition (representing 122 times the maximum recommended human dose on a body surface area basis), offspring showed decreased growth, behavioral changes, and developmental delays.

Pediatric Use The safety and effectiveness in pediatric patients have not been established.

is contraindicated in patients with: a history of hypersensitivity to sulfites or sincalide. Serious hypersensitivity reactions have included anaphylaxis and anaphylactic shock . intestinal obstruction. History of hypersensitivity to sulfites or sincalide.

Intestinal obstruction.

In the event of an overdose, symptoms related to vagal stimulation, such as gastrointestinal symptoms (abdominal cramps, nausea, vomiting and diarrhea), hypotension with dizziness or fainting may occur. Overdosage symptoms should be treated symptomatically and should be of short duration. A single bolus intravenous injection of 0.05 mcg/kg (approximately 2 to 3 times the human dose of 0.02 mcg/kg), sincalide caused hypotension and bradycardia in dogs.

In addition, higher doses injected intravenously once or repeatedly in dogs caused syncope and ECG changes (approximately 5 times the human dose of 0.02 mcg/kg). These effects were attributed to sincalide-induced vagal stimulation in that all were prevented by pretreatment with atropine or bilateral vagotomy.
