"Decades of research have shown that tetracyclines hold potential as anticancer agents, but to date, optimizing a tetracycline for oncology has proven elusive," said Guy Macdonald, President and Chief Executive Officer. "Leveraging our proprietary and productive discovery platform, we identified TP-2846, a structurally diverse tetracycline and potential new antileukemia agent with potent in vitro and in vivo activity. We look forward to further discussing the potential of TP-2846 at AACR (Free AACR Whitepaper) and building on this encouraging preclinical dataset."

"TP-2846 represents a new mechanism of action with potential application for AML patients regardless of mutation status," said Jacques Dumas, Ph.D., Chief Scientific Officer. "By using our fully synthetic technology for building tetracyclines, we have been able to optimize TP-2846 for AML, warranting its further study in this patient population."

The submission, which was initiated in December 2018, is based on data from the Phase III ARAMIS trial in men with non-metastatic castration-resistant prostate cancer (nmCRPC) showing a statistically significant improvement in metastasis-free survival (MFS) for darolutamide plus androgen deprivation therapy (ADT). Darolutamide plus ADT has shown a favorable safety profile compared to placebo plus ADT.1 These data were recently presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Genitourinary Cancers Symposium (ASCO GU) in San Francisco and published simultaneously in The New England Journal of Medicine.

"Darolutamide is highly effective in the patient population with non-metastatic castration-resistant prostate cancer, and it has a side-effect profile that parallels that of placebo. Patients who received Darolutamide had substantially longer MFS in the ARAMIS trial, and there was also a strong trend for improved overall survival. These results are truly exciting. We are looking forward to taking the next steps in bringing Darolutamide to men with nmCRPC and their treating physicians", said Christer Nordstedt, MD, PhD, Senior Vice President, Research and Development, Orion Corporation.

Bayer has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for darolutamide in men with nmCRPC. Bayer is also in discussions with other health authorities regarding a submission of darolutamide. The compound is being developed jointly by Orion Corporation and Bayer.

About ARAMIS

The ARAMIS trial is a randomized, Phase III, multi-center, double-blind, placebo-controlled trial evaluating the safety and efficacy of oral darolutamide in patients with nmCRPC who are currently being treated with ADT and are at high risk for developing metastatic disease. 1,509 patients were randomized in a 2:1 ratio to receive 600 mg of darolutamide twice a day or placebo along with ADT.

About darolutamide

Darolutamide is a non-steroidal androgen receptor antagonist with a distinct chemical structure that binds to the receptor with high affinity and exhibits strong antagonistic activity, thereby inhibiting the receptor function and the growth of prostate cancer cells. In preclinical studies, darolutamide demonstrated lower blood-brain barrier penetration compared to other currently available AR antagonists. This may also explain the overall low incidence of central nervous system (CNS)-related adverse events seen in the ARAMIS Phase III study.

In addition to the Phase III trial ARAMIS in men with nmCRPC, darolutamide is also being investigated in a Phase III study in metastatic hormone-sensitive prostate cancer (ARASENS). Information about these trials can be found at www.clinicaltrials.gov.

Darolutamide is not approved by the U.S. FDA, the European Medicines Agency or any other health authority.

About castration-resistant prostate cancer (CRPC)

Prostate cancer is the second most commonly diagnosed malignancy in men worldwide.2 In 2018, an estimated 1.2 million men were diagnosed with prostate cancer, and about 358,000 died from the disease worldwide.2 Prostate cancer is the fifth leading cause of death from cancer in men.2 Prostate cancer results from the abnormal proliferation of cells within the prostate gland, which is part of a man’s reproductive system.3 It mainly affects men over the age of 50, and the risk increases with age.4 Treatment options range from surgery to radiation treatment to therapy using hormone-receptor antagonists, i.e., substances that stop the formation of testosterone or prevent its effect at the target location.5 However, in nearly all cases, the cancer eventually becomes resistant to conventional hormone therapy.6

CRPC is an advanced form of the disease where the cancer keeps progressing even when the amount of testosterone is reduced to very low levels in the body. The field of treatment options for castration-resistant patients is evolving rapidly, but until recently, there have been no effective treatment options for CRPC patients who have rising prostate-specific antigen (PSA) levels while on ADT and no detectable metastases. In men with progressive nmCRPC, a short PSA doubling time has been consistently associated with reduced time to first metastasis and death.7

"2018 was a year of exceptional progress – in addition to generating total company net sales growth of 14 percent, we executed on our strategic objectives – advancing our pipeline and driving net sales growth of KRYSTEXXA, which increased 65 percent," said Timothy P. Walbert, chairman, president and chief executive officer, Horizon Pharma plc. "We enrolled the Phase 3 trial of our biologic candidate teprotumumab well ahead of schedule and are now expecting top-line data by the end of the first quarter.

"We are building on the momentum we established in 2018 and expect continued strong commercial execution across our operating segments," continued Walbert. "We plan to submit our biologics license application for teprotumumab in mid-2019 if the clinical data is positive and expect to initiate two important clinical trials for KRYSTEXXA, with the MIRROR trial initiating in the second quarter and a new study in kidney transplant patients with uncontrolled gout beginning in the second half of 2019."

Fourth-Quarter and Recent Company Highlights

Accelerated Teprotumumab Phase 3 Top-Line Data Read-Out Timeline: The Company announced in January that it expects top-line data results for its pivotal teprotumumab Phase 3 confirmatory trial, OPTIC (Treatment of Graves’ Orbitopathy (Thyroid Eye Disease) to Reduce Proptosis with Teprotumumab Infusions in a Randomized, Placebo-Controlled, Clinical Study), by the end of first quarter of 2019. This is accelerated from the initial second quarter of 2019 timeline, and the Company is tracking to a mid-2019 biologics license application (BLA) submission.

Teprotumumab is a fully human monoclonal antibody insulin-like growth factor-1 receptor (IGF-1R) inhibitor in Phase 3 development for the treatment of thyroid eye disease (TED), in which the muscles and fatty tissue behind the eye expand and become inflamed, which can lead to proptosis (eye bulging) and diplopia (double vision) as well as quality-of-life issues.
Phase 2 Teprotumumab Data Presented at American Thyroid Association (ATA)and American Academy of Ophthalmology (AAO) Meetings: Additional data for the pivotal Phase 2 teprotumumab trial presented at ATA and AAO demonstrated durability of the Phase 2 trial 48 weeks following the end of the treatment period (Week 24) and nearly a year off therapy. At Week 24, 71.4 percent (30 of 42) of patients responded with reductions of ≥2mm in proptosis and 61.9 percent of patients (26 of 42) responded with improvement of at least one grade in diplopia, both of which are considered a clinically meaningful change. At Week 72, 48 weeks following the study completion and nearly a year off therapy, 53.3 percent of the Week 24 proptosis responders maintained the reductions and 69.2 percent of patients with diplopia improvement maintained the benefit. These results demonstrate that teprotumumab has the potential to be the first and only disease-modifying therapy for thyroid eye disease.
New KRYSTEXXA Study in Kidney Transplant Patients with Uncontrolled Gout: The Company is announcing today that it plans to initiate a clinical trial in the second half of 2019 evaluating the effect of KRYSTEXXA, the Company’s medicine for uncontrolled gout, on serum uric acid levels in kidney transplant patients with uncontrolled gout (uncontrolled gout is chronic gout that is refractory to conventional therapies). Kidney transplant patients have more than a tenfold increase in the prevalence of gout when compared to the general population, and literature suggests that high serum uric acid levels are associated with organ rejection. Managing uncontrolled gout is one of the most common and significant unmet needs of kidney transplant patients.
New KRYSTEXXA Immunomodulation Data Presented at American College of Rheumatology/ Association of Rheumatology Health Professionals (ACR) Meeting: At the October 2018 ACR meeting, external investigators shared results from a case series of nine sequential patients with uncontrolled gout, evaluating the administration of KRYSTEXXA with the immunomodulator methotrexate to improve the durability of KRYSTEXXA response. The study stated that of the nine patients followed out to five months, all nine were responders as defined by >80 percent of serum uric acid levels being maintained at goal <6.0 mg/dL during the observation period.
Expanded Indication for RAVICTI: The Company received U.S. Food and Drug Administration (FDA) approval in December to expand the age range for chronic management of urea cycle disorders to birth and older from the previous age range of two months of age and older.
Recent Business Development Initiatives: On Dec. 28, 2018, the Company sold the rights to RAVICTI and AMMONAPS outside of North America and Japan to Medical Need Europe AB for $35 million. In addition, effective Jan. 1, 2019, the RAYOS and LODOTRA license and supply agreements were amended, including the transfer of LODOTRA to Vectura Group plc, the current third-party supplier. Beginning in 2019, the Company will no longer recognize revenue from RAVICTI and AMMONAPS sales outside of North America and Japan, or from sales of LODOTRA. AMMONAPS is known as BUPHENYL and LODOTRA is known as RAYOS in the United States.
Research and Development Programs

Orphan Candidate and Program:

Teprotumumab: The pivotal Phase 3 confirmatory study, OPTIC, is evaluating teprotumumab for the treatment of TED, which has no FDA-approved treatments. OPTIC completed enrollment September of 2018, ahead of the year-end target, and top-line results are expected by the end of first-quarter 2019. OPTIC-X, a 48-week extension study in which participants may receive up to eight additional infusions of teprotumumab, continues to enroll patients. The objective of OPTIC-X is to evaluate the potential for retreatment as well as longer duration of treatment with teprotumumab.
Rheumatology Pipeline Candidates and Programs:

KRYSTEXXA Study in Kidney Transplant Patients: The Company plans to initiate a clinical trial in the second half of 2019 evaluating the effect of KRYSTEXXA on serum uric acid levels in kidney transplant patients with uncontrolled gout. Kidney transplant patients have more than a tenfold increase in the prevalence of gout when compared to the general population, and literature suggests that high serum uric acid levels are associated with organ rejection. Managing uncontrolled gout is one of the most common and significant unmet needs of kidney transplant patients.
KRYSTEXXA Immunomodulation Study: The Company is evaluating the use of methotrexate to enhance the response rate to KRYSTEXXA through its MIRROR (Methotrexate to Increase Response Rates in Patients with UncontrolledGOut Receiving KRYSTEXXA) open-label study. Methotrexate, the immunomodulator most commonly used by rheumatologists, has been shown to reduce anti-drug antibodies when combined with other biologics. The Company is adapting MIRROR’s trial design to support the potential for registration, with enrollment expected to begin in the second quarter of 2019.
Next-generation Biologic Programs for Uncontrolled Gout: The Company is pursuing two development programs for next-generation biologics for uncontrolled gout, HZN-003 and PASylated uricase technology, to support and sustain the Company’s market leadership in uncontrolled gout. The programs are exploring the use of optimized uricase technology coupled with optimized PEGylation or PASylation technology, to improve the molecule’s half-life, with the potential for subcutaneous dosing.
Augmented Rheumatology Pipeline with HemoShear Collaboration: The Company is collaborating with HemoShear Therapeutics, LLC, a privately held biotechnology company, to discover and develop novel therapeutics for gout.
