Applies to pegloticase: intravenous solution.

Warning

Intravenous route (Solution)

Anaphylaxis and infusion reactions have been reported to occur during and after administration of pegloticase. Anaphylaxis may occur with any infusion, and generally manifests within 2 hours of the infusion. Pegloticase should be administered in healthcare settings and by healthcare providers prepared to manage anaphylaxis and infusion reactions. Premedicate with antihistamines and corticosteroids and closely monitor for anaphylaxis for an appropriate period of time after administration of pegloticase. Monitor serum uric acid levels prior to each infusion and discontinue treatment if levels increase to above 6 mg/dL, particularly when 2 consecutive levels above 6 mg/dL are observed. Screen patients at risk for G6PD deficiency prior to starting pegloticase Hemolysis and methemoglobinemia have been reported with pegloticase in patients with G6PD deficiency. Pegloticase is contraindicated in patients with G6PD deficiency.

For Healthcare Professionals

Applies to pegloticase: intravenous solution.

General

The most commonly reported adverse reactions included gout flares, infusion reactions, nausea, contusion, and ecchymosis.[Ref]

Hematologic

Life-threatening glucose-6-phosphate dehydrogenase (G6PD) deficiency associated hemolysis and methemoglobinemia have been reported in patients treated with this drug.

Frequency not reported: Glucose-6-phosphate dehydrogenase (G6PD) deficiency associated hemolysis and methemoglobinemia

Hypersensitivity

Common (1% to 10%): Anaphylaxis[Ref]

Diagnostic criteria for anaphylaxis included skin or mucosal tissue involvement, and either airway compromise, and/or reduced blood pressure with or without associated symptoms, and a temporal relationship with the injection as well as no other identifiable cause. In clinical trials, 6.5% (n=8) patients receiving this drug every 2-weeks and 4.8% (n=6) of patients receiving this drug every 4 weeks experienced anaphylaxis. All patients had been pretreated with oral antihistamine, IV corticosteroid, and/or acetaminophen. There were no instances in placebo patients. For those experiencing anaphylaxis, manifestations included wheezing, peri-oral or lingual edema, or hemodynamic instability with or without rash or urticaria. Pre-treatment may have blunted or obscured symptoms, and therefore frequency may be an underestimate.[Ref]

Local

Infusion reactions occurred in 26% of patients receiving this drug every 2-weeks and 41% of patients receiving this drug every 4 weeks. Manifestations have included urticaria, dyspnea, chest discomfort, chest pain, erythema, and pruritus. These symptoms overlap with those that constitute anaphylaxis, but in the individual patient did not satisfy the clinical criteria for anaphylaxis. Infusion reactions are thought to result from the release of various mediators, such as cytokines. They may occur at any time during the course of treatment with approximately 3% occurring with the first infusion and 91% occurring during the time of infusion. Some infusion reactions improved with the slowing of the infusion rate.[Ref]

Very common (10% or more): Infusion reactions (up to 26%)[Ref]

Other

Postmarketing reports: Asthenia, malaise

Metabolic

Very common (10% or more): Gout flares (up to 77%)[Ref]

An increase in gout flares is frequently observed upon initiation of anti-hyperuricemic therapy due to changing serum uric acid levels resulting from mobilization of urate from tissue deposits. During clinical trials, the frequency of gout flares was 74%, 81%, and 51% for patients receiving 8 mg every 2 weeks, 8 mg every 4 weeks, and placebo, respectively. In the subsequent 3 months, the frequencies were 41%, 57%, and 67%, respectively. Patients were receiving gout flare prophylaxis with colchicine and/or a NSAID.[Ref]

Cardiovascular

Common (1% to 10%): Chest discomfort, chest pain

Postmarketing reports: Peripheral swelling[Ref]

During clinical trials, 2 cases of congestive heart failure (CHF) exacerbation were reported among patients receiving 8 mg every 2 weeks. During the open-label extension study while patients continued to receive 8 mg every 2 weeks, 4 patients reported CHF exacerbation.[Ref]

Immunologic

Very common (10% or more): Anti-pegloticase antibodies (up to 92%)[Ref]

Gastrointestinal

Very common (10% or more): Nausea (up to 12%)

Common (1% to 10%): Constipation, vomiting[Ref]

Dermatologic

Contusions were generally not reported on the day of infusion; most were thought to be related to other factors such as concomitant medications relevant to contusion or ecchymosis, type 1 diabetes mellitus.[Ref]

Very common (10% or more): Contusion (up to 11%), ecchymosis (up to 11%), urticaria (up to 10.8%)

Common (1% to 10%): Erythema, pruritus[Ref]

Respiratory

Common (1% to 10%): Dyspnea, nasopharyngitis[Ref]
