Drug Details [pdf]

  • 1 INDICATIONS AND USAGE

    OLPRUVA is indicated as adjunctive therapy to standard of care, which includes dietary management, for the chronic management of adult and pediatric patients weighing 20 kg or greater and with a body surface area (BSA) of 1.2 m2 or greater, with urea cycle disorders (UCDs) involving deficiencies of carbamylphosphate synthetase (CPS), ornithine transcarbamylase (OTC), or argininosuccinic acid synthetase (AS).

    Limitations of Use

    Episodes of acute hyperammonemia may occur in patients while on OLPRUVA. OLPRUVA is not indicated for the treatment of acute hyperammonemia, which can be a life-threatening medical emergency that requires rapid acting interventions to reduce plasma ammonia levels.

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Recommended Dosage

    OLPRUVA treatment should be supervised by a healthcare provider experienced in the treatment of urea cycle disorders.

    The recommended dosage of OLPRUVA for patients with urea cycle disorders is 9.9 –13 g/m2/day orally. Divide the calculated total daily dose into three to six doses. Administer as three to six divided doses and take with food.

    Round each individual dose of OLPRUVA to the nearest available dosage strength. The maximum dosage is 20 grams per day. Combine OLPRUVA with dietary protein restriction and, in some cases, amino acid supplementation (e.g., essential amino acids, arginine, citrulline, and protein-free calorie supplements).

    If a dose is missed, take the missed dose as soon as possible on the same day.

    2.2 Dosage Administration and Monitoring

    Monitor plasma ammonia levels to determine the need for dosage adjustment. Adjust the OLPRUVA dosage to maintain the plasma ammonia level within the normal range for the patient's age, taking into consideration their clinical condition (e.g., nutritional requirements, protein intake, growth parameters, etc.).

    Monitor patients for potential neurotoxicity and obtain measurements of plasma phenylacetate and phenylacetylglutamine levels [see Warnings and Precautions (5.1), Adverse Reactions (6)]. If neurologic symptoms (e.g., vomiting, nausea, headache, somnolence, or confusion) are present in the absence of high ammonia levels or other incurrent illnesses, consider reducing the dose of OLPRUVA.

    2.3 Dosage Adjustment in Patients with Hepatic Impairment

    For patients with hepatic impairment, start at the lower end of the recommended dosing range and maintain patients on the lowest dose necessary to control plasma ammonia levels [see Use in Specific Populations (8.7)].

    2.4 Preparation and Administration Instructions

    For oral administration only. Do not administer via gastrostomy or nasogastric tubes.

    1. Pour the entire contents of the Mix-Aid packet into approximately 4 ounces of water in a cup and stir, forming a suspension.
    2. Pour the entire contents of the OLPRUVA packet(s) into the suspension and stir.
    3. Drink the entire suspension within 5 minutes after stirring to minimize dissolution of coating. After 30 minutes, the suspension should be discarded.
    4. Pour another 4 ounces of water into the cup and drink to make sure that any OLPRUVA remaining in the cup is consumed.
  • 3 DOSAGE FORMS AND STRENGTHS

    For oral suspension:

    2 g, 3 g, 4 g, 5 g, 6 g, and 6.67 g of sodium phenylbutyrate as white to off-white pellets in packet(s) for reconstitution.

  • 4 CONTRAINDICATIONS

    None.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Neurotoxicity of Phenylacetate

    Increased exposure to phenylacetate, the major metabolite of OLPRUVA, may be associated with neurotoxicity in patients with UCDs. In a study of adult cancer patients receiving intravenous phenylacetate, 250-300 mg/kg/day for 14 days, repeated at 4-week intervals, signs and symptoms of neurotoxicity, which were reversible upon discontinuation, were seen at plasma concentrations ≥ 3.5 mmol/L, and included somnolence, fatigue, and light headedness [see Adverse Reactions (6)]. OLPRUVA is not approved for intravenous use or for treatment of patients with cancer.

    If symptoms of vomiting, nausea, headache, somnolence, or confusion are present in the absence of high ammonia levels or other intercurrent illnesses, consider reducing the dose of OLPRUVA [see Dosage and Administration (2.2)].

    Phenylacetate caused neurotoxicity when given subcutaneously in rat pups [see Use in Specific Populations (8.4)].

    5.2 Hypokalemia

    Renal excretion of phenylacetylglutamine may induce urinary loss of potassium. Monitor serum potassium during therapy and initiate appropriate treatment when necessary.

    5.3 Conditions Associated with Edema

    OLPRUVA contains 124 mg (5.4 mmol) of sodium per gram of sodium phenylbutyrate (12.4% w/w) and the Mix-Aid contains 5 mg of sodium per packet, corresponding to 2.5 g (108 mmol) of sodium in the maximum daily dose of 20 g of OLPRUVA. In order to decide if administration of OLPRUVA is appropriate in patients with diseases that involve edema, such as heart failure, cirrhosis, or nephrosis, calculate the total amount of sodium patients will be exposed to based on their BSAs [see Dosage and Administration (2.1)]. If a patient develops new-onset edema or worsening edema while on treatment, discontinue administration of OLPRUVA and initiate appropriate therapy.

  • 6 ADVERSE REACTIONS

    The following adverse reactions associated with the use of sodium phenylbutyrate were identified in clinical studies or postmarketing reports. Because some of these reactions were 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.

    Most common adverse reactions (incidence ≥ 3%) are amenorrhea or menstrual dysfunction (irregular menstrual cycles), decreased appetite, body odor and bad taste or taste aversion.

    Less Common Clinical Adverse Reactions

    Blood and lymphatic system disorders: aplastic anemia, ecchymoses

    Cardiac disorders: arrhythmia

    Gastrointestinal disorders: abdominal pain, gastritis, nausea and vomiting, constipation, rectal bleeding, peptic ulcer disease, pancreatitis

    Metabolism and nutrition disorders: increased weight, edema

    Nervous system disorders: syncope, headache

    Psychiatric disorders: depression

    Renal and urinary disorders: renal tubular acidosis

    Skin and subcutaneous tissue disorders: rash

    Laboratory Adverse Reactions

    Blood and lymphatic system disorders: anemia, leukopenia and leukocytosis, thrombocytopenia, thrombocytosis

    Hepatobiliary disorders: hyperbilirubinemia, increased blood alkaline phosphatase, increased transaminases

    Metabolism and nutrition disorders: acidosis, alkalosis, hyperchloremia, hypophosphatemia, hyperuricemia, hyperphosphatemia, hypernatremia, hypokalemia, hypoalbuminemia, decreased total protein

    Clinical Adverse Reactions with Use of Phenylacetate

    Nervous system disorders: Neurotoxicity was reported in cancer patients receiving intravenous phenylacetate, the major metabolite of OLPRUVA (OLPRUVA is not approved for intravenous use or for treatment of patients with cancer). Signs and symptoms were predominately somnolence, fatigue, and dizziness (lightheadedness); less frequently reported were headache, dysgeusia, hypoacusis, disorientation, memory impairment, and exacerbation of a pre-existing neuropathy.

  • 7 DRUG INTERACTIONS

    7.1 Potential for Other Drugs to Affect Ammonia

    Corticosteroids

    Use of corticosteroids may cause the breakdown of body protein and increase plasma ammonia levels.

    Valproic Acid and Haloperidol

    Hyperammonemia may be induced by haloperidol and by valproic acid.

    Monitor plasma ammonia levels closely when corticosteroids, valproic acid, or haloperidol is used concomitantly with OLPRUVA.

    7.2 Potential for Other Drugs to Affect OLPRUVA

    Probenecid

    Probenecid may inhibit renal excretion of the metabolites of OLPRUVA including phenylacetate and phenylacetylglutamine. Monitor patients for potential neurotoxicity and measure plasma phenylacetate and phenylacetylglutamine levels when probenecid is used concomitantly with OLPRUVA [see Dosage and Administration (2.2)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Available data with sodium phenylbutyrate use in pregnant women are insufficient to identify a drug associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with sodium phenylbutyrate. Based on published animal data, phenylacetate may be neurotoxic to the developing brain (see Data).

    There are serious risks to the mother and fetus associated with untreated urea cycle disorders during pregnancy which can result in serious morbidity and mortality to the mother and fetus (see Clinical Considerations).

    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.

    Clinical Considerations

    Disease-Associated Maternal and/or Embryo/Fetal Risk

    Pregnancy is a time of increased metabolic demand which increases the risk for hyperammonemic episodes when metabolic demands are not met. Hyperammonemic episodes in pregnancy are associated with impaired cognition in the mother and an increased risk of maternal and fetal death.

    Data

    Animal Data

    In rats, intrauterine exposure to phenylacetate produced lesions in the neonatal brain in layer 5 of the cortical pyramidal cells; dendritic spines were longer and thinner than normal and reduced in number.

    8.2 Lactation

    Risk Summary

    There are no data on the presence of sodium phenylbutyrate and its metabolite in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for OLPRUVA and any potential adverse effects on the breastfed infant from OLPRUVA or from the underlying maternal condition.

    8.4 Pediatric Use

    The safety and effectiveness of OLPRUVA have been established as adjunctive therapy to the standard of care, which includes dietary management, in the chronic management of pediatric patients weighing 20 kg or greater and with a body surface area 1.2 m2 or greater, with urea cycle disorders (UCDs) involving deficiencies of carbamylphosphate synthetase (CPS), ornithine transcarbamylase (OTC), or argininosuccinic acid synthetase (AS).

    OLPRUVA is not indicated for the treatment of acute hyperammonemia which can be a life-threatening medical emergency that requires rapid acting interventions to reduce plasma ammonia levels.

    The sodium content of OLPRUVA has the potential to cause new-onset edema or worsening edema from salt and water retention, particularly in patients with underlying predisposing conditions [see Warnings and Precautions (5.3)].

    OLPRUVA is not approved in pediatric patients weighing less than 20 kg or in pediatric patients weighing 20 kg or greater with a BSA of less than 1.2 m2.

    Neurotoxicity has been observed in juvenile animals with phenylacetate exposure [see Warnings and Precautions (5.1)].

    Juvenile Animal Toxicity Data

    When given subcutaneously to neonatal rats, 190-474 mg/kg phenylacetate caused decreased proliferation and increased loss of neurons, and it reduced CNS myelin. Cerebral synapse maturation was retarded, and the number of functioning nerve terminals in the cerebrum was reduced, which resulted in impaired brain growth.

    8.5 Geriatric Use

    Clinical studies of OLPRUVA did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.

    8.6 Renal Impairment

    No studies with OLPRUVA were conducted in subjects with renal impairment. Monitor plasma ammonia levels when starting patients with impaired renal function on OLPRUVA [see Clinical Pharmacology (12)].

    8.7 Hepatic Impairment

    No studies with OLPRUVA were conducted in subjects with hepatic impairment. Start at the lower end of the recommended dosing range and maintain patients with hepatic impairment on the lowest dose necessary to control plasma ammonia levels [see Clinical Pharmacology (12), Dosage and Administration (2.3)].

  • 10 OVERDOSAGE

    Overdoses of OLPRUVA exceeding ten-fold the maximum recommended dosage may produce emesis, CNS depression, metabolic acidosis with or without respiratory alkalosis, hypernatremia, hypokalemia, and hypophosphatemia. Symptoms of overdose overlap with those of acute hyperammonemia. If overdose occurs, discontinue OLPRUVA, monitor plasma phenylacetate and ammonia levels closely, and institute appropriate emergency management, which may include hemodialysis, continuous veno-venous hemofiltration (CVVH) or extracorporeal membrane oxygenation (ECMO).

  • 11 DESCRIPTION

    OLPRUVA (sodium phenylbutyrate) for oral suspension is a nitrogen binding agent. Sodium phenylbutyrate is a white to yellowish-white powder. It is freely soluble in water and in methanol, and practically insoluble in acetone and diethyl ether. It is known chemically as sodium 4-phenylbutyrate with a molecular weight of 186.19 and molecular formula C10H11NaO2.

    Structural Formula:

    Structural Formula

    OLPRUVA is supplied in dosage envelopes containing 2 g (equivalent to 1.75 g phenylbutyrate), 3 g (equivalent to 2.63 g phenylbutyrate), 4 g (equivalent to 3.51 g phenylbutyrate), 5 g (equivalent to 4.38 g phenylbutyrate), 6 g (equivalent to 5.26 g phenylbutyrate), and 6.67 g (equivalent to 5.85 g phenylbutyrate) of sodium phenylbutyrate in one or two packets. OLPRUVA is a polymer coated formulation which contains the following inactive ingredients: amino methacrylate copolymer, hypromellose, microcrystalline cellulose, polyethylene glycol 6000, silicon dioxide, and talc.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Sodium phenylbutyrate is a pro-drug and is metabolized to phenylacetate. Phenylacetate is a metabolically active compound that conjugates with glutamine via acetylation to form phenylacetylglutamine. Phenylacetylglutamine is excreted by the kidneys, hence providing an alternate vehicle for waste nitrogen excretion.

    12.2 Pharmacodynamics

    In patients with urea cycle disorders, sodium phenylbutyrate decreased elevated plasma ammonia and glutamine levels.

    12.3 Pharmacokinetics

    The pharmacokinetics of phenylbutyrate and its metabolite phenylacetate were characterized in healthy adult subjects following a single oral administration of OLPRUVA (5 g of sodium phenylbutyrate) with suspension agent under fasted and fed conditions.

    Absorption

    The pharmacokinetic parameters for the maximum plasma concentration (Cmax) and area under the plasma concentration-time curve (AUC) of phenylbutyrate and phenylacetate under fasted conditions are summarized in Table 1.

    Table 1 Cmax and AUC of Phenylbutyrate and Phenylacetate Following a Single Oral Dose Administration of OLPRUVA (5 g) in Healthy Subjects Under Fasted Conditions
    PK ParametersPhenylbutyrate Results
    (Mean ± SD)
    Phenylacetate Results
    (Mean ± SD)
    Cmax (μg/mL) 229 ± 48 39 ± 14
    AUCinf (hrμg/mL) 510 ± 129 183 ± 76

    Effect of Food

    Compared to those under fasted conditions, phenylbutyrate Cmax was decreased by 50% and AUCinf decreased by 39% when OLPRUVA was administered with a high-fat meal (total 980 calories with 55% fat). For the metabolite phenylacetate, Cmax decreased by 32% and AUCinf decreased by 29% with a high-fat meal compared to fasted conditions.

    Distribution

    The apparent volume of distribution of phenylbutyrate was 7.2 L under fasted conditions.

    Elimination

    The mean half-life of phenylbutyrate was 0.5 hours under fasted conditions. The mean half-life of phenylacetate was 1.2 hours under fasted conditions.

    Metabolism

    Following oral administration, sodium phenylbutyrate is metabolized by β-oxidation into phenylacetate which is converted to its coenzyme A ester, phenylacetyl-coenzyme A and further conjugated with glutamine to form phenylacetylglutamine. Phenylacetylglutamine is excreted by the kidneys. The major sites for metabolism of sodium phenylbutyrate are the liver and kidneys. Phenylacetate is also hydrolyzed by esterases in liver and blood.

    Excretion

    Approximately 80-100% of sodium phenylbutyrate is excreted by the kidneys within 24 hours as phenylacetylglutamine. For each gram of sodium phenylbutyrate administered, it is estimated that between 0.12-0.15 grams of phenylacetylglutamine nitrogen are produced.

    Specific Populations

    Patients with Renal Impairment or Hepatic Impairment

    OLPRUVA has not been studied in patients with renal impairment or in patients with hepatic impairment.

    Drug Interaction Studies

    In vitro or clinical studies with OLPRUVA for determination of potential drug-drug interaction have not been conducted.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenicity, mutagenicity, and fertility studies of sodium phenylbutyrate have not been conducted.
