-- Oral presentation on KRYSTEXXA® (pegloticase injection) plus methotrexate to be held June 2, 2022 at 11:35 a.m. CEST--
-- Additional data presentations provide new insights on psychosocial and comorbidity impact of gout to help inform evolving treatment strategies --
Horizon Therapeutics plc (Nasdaq: HZNP) today announced a series of data presentations during The EULAR 2022 European Congress of Rheumatology, June 1 – 4 in Copenhagen.
As part of Horizon’s efforts to continually improve the understanding and treatment of gout, the company will present data on KRYSTEXXA® (pegloticase injection), including six-month results from the MIRROR randomized controlled trial, as well as data from the PROTECT trial. The company will also present data on the experiences of people with gout, including comorbidities, complications and the potential impact of stigma on treatment considerations.
“The EULAR congress provides an important opportunity to discuss our findings with leading global experts in rheumatology and to understand how new insights can improve patient care,” said Theresa Podrebarac M.D., MSc., senior vice president, clinical development, Horizon. “Importantly, we look forward to sharing data on the MIRROR randomized controlled trial, which demonstrated a significant improvement in response rate and overall safety. We believe data like this will reset the current standard of care for uncontrolled gout patients.”

INDICATION AND USAGE
KRYSTEXXA® (pegloticase injection) is a PEGylated uric acid specific enzyme indicated for the treatment of chronic gout in adult patients refractory to conventional therapy.
Gout refractory to conventional therapy occurs in 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.
Important Limitations of Use: KRYSTEXXA is not recommended for the treatment of asymptomatic hyperuricemia.
IMPORTANT SAFETY INFORMATION
WARNING: ANAPHYLAXIS AND INFUSION REACTIONS
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. However, delayed-type hypersensitivity reactions have also been reported. KRYSTEXXA should be administered in healthcare settings and by healthcare providers prepared to manage anaphylaxis and infusion reactions. Patients should be premedicated with antihistamines and corticosteroids. Patients should be closely monitored for an appropriate period of time for anaphylaxis after administration of KRYSTEXXA. Serum uric acid levels should be monitored prior to infusions, and healthcare providers should consider discontinuing treatment if levels increase to above 6 mg/dL, particularly when 2 consecutive levels above 6 mg/dL are observed.
The risk of anaphylaxis and infusion reactions is higher in patients who have lost therapeutic response.
Concomitant use of KRYSTEXXA and oral urate-lowering agents may blunt the rise of sUA levels. Patients should discontinue oral urate-lowering agents and not institute therapy with oral urate-lowering agents while taking KRYSTEXXA.
In the event of anaphylaxis or infusion reaction, the infusion should be slowed, or stopped and restarted at a slower rate.
Patients should be informed of the symptoms and signs of anaphylaxis and instructed to seek immediate medical care should anaphylaxis occur after discharge from the healthcare setting.
CONTRAINDICATIONS: G6PD DEFICIENCY ASSOCIATED HEMOLYSIS AND METHEMOGLOBINEMIA
Patients should be screened for G6PD deficiency prior to starting KRYSTEXXA. Hemolysis and methemoglobinemia have been reported with KRYSTEXXA in patients with G6PD deficiency. KRYSTEXXA should not be administered to these patients.
An increase in gout flares is frequently observed upon initiation of anti-hyperuricemic therapy, including treatment with KRYSTEXXA. If a gout flare occurs during treatment, KRYSTEXXA need not be discontinued. 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 studied in patients with congestive heart failure, but some patients in the clinical trials experienced exacerbation. Caution should be exercised when using KRYSTEXXA in patients who have congestive heart failure, and patients should be monitored closely following infusion.
The most commonly reported adverse reactions in clinical trials with KRYSTEXXA were gout flares, infusion reactions, nausea, contusion or ecchymosis, nasopharyngitis, constipation, chest pain, anaphylaxis and vomiting.
