Gout is a type of
arthritis associated with
high amounts of uric
acid, also known as
hyperuricemia.1,3
  • When uric acid builds up, it can turn into crystals that cause painful flares, tophi, and other symptoms of gout2
  • Uric acid crystals can deposit almost anywhere in the body, in organs like the kidney and heart and in the joints and bones1,2

KRYSTEXXA has not been studied to reverse damage to the kidneys, heart, or any organ.

Identifying uncontrolled gout in your patients10

Identifying patients with uncontrolled gout is the first step to getting them appropriate treatment.

KRYSTEXXA is not indicated for the treatment of pain.

sUA, serum uric acid; ULTs, urate-lowering therapies.

While diet can help manage flares, it won’t treat the underlying
cause of gout11

Only one-third of uric acid crystal buildup in the body comes from what patients eat.11 For many patients, uric acid crystal buildup is primarily due to:

Genetics

Some people are naturally prone to retaining higher levels of uric acid12

Renal icon Renal icon Renal icon

Renal issues

Chronic kidney disease (CKD) can make it harder for the body to remove uric acid13

Even an improvement in diet can lower uric acid levels by only ~1 mg/dL.14

Pharmacologic
strategies to manage
gout

Oral gout treatments focus on either addressing acute symptoms or reducing uric acid levels but may not be sufficient for patients with uncontrolled gout.

Reduce symptoms of gout flare

  • Antigout anti-inflammatory agent
  • Non-steroidal anti-inflammatory drugs (NSAIDs)
  • Corticosteroids

Chronic15-17

Lower uric acid levels

  • Xanthine oxidase inhibitors (XOIs)
  • Uricosurics
  • Uricase

Even with a uric acid level of 5.4 mg/dL, it would take 2 years to dissolve a lump of uric acid the size of a small marble.18§

Help patients
understand the impact
of reducing their uric
acid levels

To reduce uric acid crystal buildup, a patient’s sUA must be low enough for crystals to dissolve.
Graphic showing uric acid levels above 6 mg/dL are associated with increased risk of future flares and joint damage, while uric acid levels below 6 mg/dL are associated with decreased risk of future flares and joint damage Graphic showing uric acid levels above 6 mg/dL are associated with increased risk of future flares and joint damage, while uric acid levels below 6 mg/dL are associated with decreased risk of future flares and joint damage Graphic showing uric acid levels above 6 mg/dL are associated with increased risk of future flares and joint damage, while uric acid levels below 6 mg/dL are associated with decreased risk of future flares and joint damage
  • Treat-to-target guidelines recommend lowering the sUA level to a minimum of <6 mg/dL10
  • Lowering the sUA level to <5 mg/dL may be needed to more rapidly dissolve crystals and reduce flare frequency20

Lower sUA levels have been shown to increase the speed of tophus resolution and reduce the frequency of flares, suggesting that a lower sUA target may be preferred for patients with more severe gout10

The lower the sUA level, the faster crystal buildup will dissolve10

IMPORTANT SAFETY INFORMATION

WARNING: ANAPHYLAXIS AND INFUSION REACTIONS, G6PD DEFICIENCY ASSOCIATED HEMOLYSIS AND METHEMOGLOBINEMIA

  • Anaphylaxis and infusion reactions have been reported to occur during and after administration of KRYSTEXXA.
  • Anaphylaxis may occur with any infusion, including a first infusion, and generally manifests within 2 hours of the infusion. Delayed hypersensitivity reactions have also been reported.
  • KRYSTEXXA 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 after administration of KRYSTEXXA.
  • 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 glucose-6-phosphate dehydrogenase (G6PD) deficiency prior to starting KRYSTEXXA. Hemolysis and methemoglobinemia have been reported with KRYSTEXXA in patients with G6PD deficiency. KRYSTEXXA is contraindicated in patients with G6PD deficiency.

CONTRAINDICATIONS:

  • In patients with G6PD deficiency.
  • In patients with history of serious hypersensitivity reactions, including anaphylaxis, to KRYSTEXXA or any of its components.

WARNINGS AND PRECAUTIONS

Gout Flares: An increase in gout flares is frequently observed upon initiation of anti-hyperuricemic therapy, including KRYSTEXXA. Gout flare prophylaxis with a non-steroidal anti-inflammatory drug (NSAID) or colchicine is recommended starting at least 1 week before initiation of KRYSTEXXA therapy and lasting at least 6 months, unless medically contraindicated or not tolerated.

Congestive Heart Failure: KRYSTEXXA has not been formally studied in patients with congestive heart failure, but some patients in the pre-marketing placebo-controlled clinical trials experienced exacerbation. Exercise caution in patients who have congestive heart failure and monitor patients closely following infusion.

ADVERSE REACTIONS

The most commonly reported adverse reactions (≥5%) are:

KRYSTEXXA co-administration with methotrexate trial:

KRYSTEXXA with methotrexate: gout flares, arthralgia, COVID-19, nausea, and fatigue; KRYSTEXXA alone: gout flares, arthralgia, COVID-19, nausea, fatigue, infusion reaction, pain in extremity, hypertension, and vomiting.

KRYSTEXXA pre-marketing placebo-controlled trials:

gout flares, infusion reactions, nausea, contusion or ecchymosis, nasopharyngitis, constipation, chest pain, anaphylaxis, and vomiting.

INDICATION

KRYSTEXXA® (pegloticase) is indicated for the treatment of chronic gout in adult patients who have failed to normalize serum uric acid and whose signs and symptoms are inadequately controlled with xanthine oxidase inhibitors at the maximum medically appropriate dose or for whom these drugs are contraindicated.

Limitations of Use: KRYSTEXXA is not recommended for the treatment of asymptomatic hyperuricemia.
