DUBLIN - Horizon Therapeutics plc (Nasdaq: HZNP) today announced updates on its 2020 financial results, TEPEZZA supply and new KRYSTEXXA trials.

'Amid the most challenging environment we have ever faced, we had a record year of performance, exceeding our full-year 2020 net sales and adjusted EBITDA guidance, driven by the significant outperformance of TEPEZZA and the strong second-half performance of KRYSTEXXA,' said Tim Walbert, chairman, president and chief executive officer, Horizon. 'We delivered exceptional shareholder value while expanding our pipeline, with six programs expected to begin this year, including two new KRYSTEXXA programs. Additionally, we successfully completed the first increased scale TEPEZZA lot and we are on track to submit the resultant data to the FDA by the end of this month.'

Full-Year 2020 Preliminary Financial Results (unaudited)

Full-year 2020 net sales exceeded the high end of the Company's guidance range of $2.12 billion to $2.14 billion; exceeding the high end of this guidance range represents year-over-year growth of more than 65 percent.

Full-year 2020 adjusted EBITDA exceeded the high end of the Company's guidance range of $920 million to $940 million; exceeding the high end of this guidance range represents year-over-year growth of more than 95 percent and an adjusted EBITDA margin expansion of more than 700 basis points compared to 2019.

The outperformance was driven by strong net sales from its two key growth drivers, TEPEZZA, its biologic for the treatment of Thyroid Eye Disease (TED), and KRYSTEXXA, its biologic for the treatment of uncontrolled gout (chronic gout refractory to conventional therapy), as well as continued growth of its Rare Disease Business Unit.

TEPEZZA full-year 2020 net sales exceeded $800 million, with double-digit sequential growth in the fourth quarter of 2020.

KRYSTEXXA full-year 2020 net sales exceeded $400 million, with double-digit sequential growth in the fourth quarter of 2020.

Cash and cash equivalents at Dec. 31, 2020 were $2.08 billion and gross leverage was less than 1.1 times.

These preliminary financial results are unaudited and subject to adjustment. Horizon will report its final fourth quarter and full-year 2020 financial results in February.

TEPEZZA Supply Update

As previously announced on Dec. 17, 2020 the Company expects a short-term disruption in TEPEZZA supply as a result of government-mandated COVID-19 vaccine production orders related to Operation Warp Speed that dramatically restricted capacity available for TEPEZZA at its drug product contract manufacturer, Catalent. The Company anticipates that this drug supply shortage could last through the first quarter. The length of the TEPEZZA supply disruption will depend on whether future manufacturing slots are successfully completed as well as decisions by the U.S. Food and Drug Administration (FDA) regarding the increased scale manufacturing process of TEPEZZA.

The Company has made significant progress with TEPEZZA drug product supply over the last several weeks, successfully completing its first manufacturing lot at increased scale and beginning its second manufacturing lot at increased scale. The Company continues to expect to submit data this month from the first increased scale drug product manufacturing lot to the FDA for its review and approval.

Pipeline Update

The Company also announced two new KRYSTEXXA development programs it expects to begin in 2021, bringing the total number of programs in its pipeline to 14.

KRYSTEXXA monthly dosing trial: This open-label trial will evaluate a monthly dosing regimen of KRYSTEXXA, with methotrexate, to treat people with uncontrolled gout. The current dosing schedule for KRYSTEXXA is every other week. The goal of the trial is to explore whether a monthly dosing regimen can provide similar outcomes as the current dosing schedule.

KRYSTEXXA retreatment trial: This open-label trial will evaluate KRYSTEXXA, with methotrexate, in patients who have previously failed KRYSTEXXA. The goal of the trial is to evaluate whether patients can benefit from KRYSTEXXA, with methotrexate, after developing an immune response to KRYSTEXXA when taken alone. Patients who have previously failed KRYSTEXXA have limited options available to address their uncontrolled gout.
