Incyte Announces U.S. FDA Approval of Opzelura™ (ruxolitinib) Cream, a Topical JAK Inhibitor, for the Treatment of Atopic Dermatitis (AD)

- Opzelura is the first and only topical Janus kinase (JAK) inhibitor approved in the United States

- In Phase 3 studies, Opzelura significantly reduced the skin inflammation and itch associated with AD

- Investor conference call and webcast scheduled for September 22, 2021, at 8:00 a.m. ET

Incyte INCY today announced that the U.S. Food and Drug Administration (FDA) has approved Opzelura™ (ruxolitinib) cream for the short-term and non-continuous chronic treatment of mild to moderate atopic dermatitis (AD) in non-immunocompromised patients 12 years of age and older whose disease is not adequately controlled with topical prescription therapies, or when those therapies are not advisable. Opzelura is the first and only topical formulation of a JAK inhibitor approved in the United States. Research shows dysregulation of the JAK-STAT pathway contributes to key features of AD such as itch, inflammation and skin barrier dysfunction¹.

"Atopic dermatitis is a chronic immune-mediated disease that can be challenging to manage. Many patients do not respond well to existing treatments and have uncontrolled disease," said Jonathan Silverberg, M.D., Ph.D., M.P.H., Associate Professor of Dermatology and Director of Clinical Research and Contact Dermatitis at The George Washington University School of Medicine and Health Sciences. "As a clinician, I am excited to have a non-steroidal topical cream like Opzelura."

"The approval of Opzelura is an important advancement in the treatment of AD, and we are pleased to offer a novel topical treatment option that targets a pathway believed to be a source of inflammation," said Hervé Hoppenot, Chief Executive Officer, Incyte. "At Incyte, we are committed to transforming the treatment of immune-mediated dermatologic conditions like AD. We look forward to bringing Opzelura to the patient community and also continuing to explore its potential in other challenging skin diseases."

The FDA approval was based on data from the TRuE-AD (Topical Ruxolitinib Evaluation in Atopic Dermatitis) clinical trial program, consisting of two randomized, double-blind, vehicle-controlled Phase 3 studies (TRuE-AD1 and TRuE-AD 2) evaluating the safety and efficacy of Opzelura in more than 1,200 adolescents and adults with mild to moderate AD. Results from the studies showed patients experienced significantly clearer skin and itch reduction when treated with Opzelura cream 1.5% twice daily (BID), compared to vehicle (non-medicated cream):

• Significantly more patients treated with Opzelura achieved Investigator's Global Assessment (IGA) Treatment Success (IGA-TS, primary endpoint) at Week 8 (defined as an IGA score of 0 [clear] or 1 [almost clear] with at least a 2-point improvement from baseline): 53.8% in TRuE-AD1 and 51.3% in TRuE-AD2, compared to vehicle (15.1% in TRuE-AD1, 7.6% in TRuE-AD2; P<0.0001).

• Significantly more patients treated with Opzelura experienced a clinically meaningful reduction in itch from baseline at Week 8, as measured by a ≥4-point reduction in the itch Numerical Rating Scale (itch NRS4): 52.2% in TRuE-AD1 and 50.7% in TRuE-AD2, compared to vehicle (15.4% in TRuE-AD1, 16.3% in TRuE-AD2; P<0.0001), among patients with an NRS score of at least 4 at baseline.

In clinical trials, the most common (≥1%) treatment-emergent adverse reactions in patients treated with Opzelura were nasopharyngitis, diarrhea, bronchitis, ear infection, eosinophil count increased, urticaria, folliculitis, tonsillitis and rhinorrhea². See Important Safety Information below, including Boxed Warnings for serious infections, mortality, malignancy, major adverse cardiovascular events and thrombosis, seen with JAK inhibitors for inflammatory conditions.

"It can be hard for people to fully appreciate how difficult AD can be and the tremendous impact it has on patients," said Julie Block, President & CEO, National Eczema Association. "The chronic itch is difficult to cope with and related sleep issues can be exhausting. Many patients and their dermatologists are looking for additional options to meet current unmet needs in the management of AD. The approval of Opzelura is exciting news, and we welcome a new treatment option for our community."

AD is a chronic skin disease affecting more than 21 million people aged 12 years and older in the U.S. and is characterized by inflammation and itch³. Signs and symptoms include irritated and itchy skin that can cause red lesions that may ooze and crust. People with AD are also more susceptible to bacterial, viral and fungal infections⁴.

About TRuE-AD

The TRuE-AD clinical trial program evaluating the safety and efficacy of ruxolitinib cream compared to vehicle (non-medicated cream) in patients with atopic dermatitis (AD) consists of two randomized, double-blind, vehicle-controlled Phase 3 studies: TRuE-AD1 (NCT03745638) and TRuE-AD2 (NCT03745651). Both studies enrolled more than 600 patients (age ≥12 years) who had been previously diagnosed with AD for at least two years and who were candidates for topical therapy.

Key findings from the TRuE-AD1 and TRuE-AD2 studies were presented at the European Academy of Dermatology and Venereology (EADV) Congress, Revolutionizing Atopic Dermatitis Virtual Symposium and previously announced by Incyte.

IMPORTANT SAFETY INFORMATION

OPZELURA cream is for use on the skin only. Do not use OPZELURA cream in your eyes, mouth or vagina.

OPZELURA may cause serious side effects, including:

Serious Infections: OPZELURA cream contains ruxolitinib. Ruxolitinib belongs to a class of medicines called Janus kinase (JAK) inhibitors. JAK inhibitors are medicines that affect your immune system. JAK inhibitors can lower the ability of your immune system to fight infections. Some people have had serious infections while taking JAK inhibitors by mouth, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have been hospitalized or died from these infections. Some people have had serious infections of their lungs while taking OPZELURA. Your healthcare provider should watch you closely for signs and symptoms of TB during treatment with OPZELURA.

OPZELURA should not be used in people with an active, serious infection, including localized infections. You should not start using OPZELURA if you have any kind of infection unless your healthcare provider tells you it is okay. You may be at a higher risk of developing shingles (herpes zoster) while using OPZELURA.

Increased risk of death from all causes, including sudden cardiac death, has happened in people taking JAK inhibitors by mouth.

Cancer and immune system problems: OPZELURA may increase your risk of certain cancers by changing the way your immune system works. Some people have had lymphoma and other cancers while taking JAK inhibitors by mouth, especially if they are a current or past smoker. Some people have had skin cancers while taking OPZELURA. Your healthcare provider will regularly check your skin during your treatment with OPZELURA.

There is an increased risk of major cardiovascular events such as heart attack, stroke or cardiac death in people with cardiovascular risk factors and who are current or past smokers while using JAK inhibitors to treat inflammatory conditions.

Blood clots: Blood clots in the veins of your legs (deep vein thrombosis, DVT) or lungs (pulmonary embolism, PE) can happen in some people taking OPZELURA. This may be life-threatening.

Low blood cell counts: OPZELURA may cause low platelet counts (thrombocytopenia), low red blood cell counts (anemia), and low white blood cell counts (neutropenia). If needed, your healthcare provider will do a blood test to check your blood cell counts during your treatment with OPZELURA and may stop your treatment if signs or symptoms of low blood cell counts happen.

Cholesterol increases: Cholesterol increase has happened in people when ruxolitinib is taken by mouth. Tell your healthcare provider if you have high cholesterol or triglycerides.

Before starting OPZELURA, tell your healthcare provider if you:

• have an infection, are being treated for one, or have an infection that keeps coming back
• have diabetes, chronic lung disease, HIV, or a weak immune system
• have TB or have been in close contact with someone with TB
• have had shingles (herpes zoster) or hepatitis B or C
• live, have lived in, or have traveled to certain parts of the country (such as the Ohio and Mississippi River valleys and the Southwest) where there is an increased chance for getting certain kinds of fungal infections. These infections may happen or become more severe if you use OPZELURA. Ask your healthcare provider if you do not know if you have lived in an area where these infections are common.
• think you have an infection or have symptoms of an infection such as:

• have ever had any type of cancer, or are a current or past smoker.
• have had blood clots in the veins of your legs or lungs in the past.
• have high cholesterol or triglycerides
• have or have had low white or red blood cell counts
• are pregnant or plan to become pregnant. It is not known if OPZELURA will harm your unborn baby. There is a pregnancy exposure registry for individuals who use OPZELURA during pregnancy. The purpose of this registry is to collect information about the health of you and your baby. If you become exposed to OPZELURA during pregnancy, you and your healthcare provider should report exposure to Incyte Corporation at 1-855-463-3463.
• are breastfeeding or plan to breastfeed. It is not known if OPZELURA passes into your breast milk. Do not breastfeed during treatment with OPZELURA and for about 4 weeks after the last dose.

After starting OPZELURA:

• Call your healthcare provider right away if you have any symptoms of an infection. OPZELURA can make you more likely to get infections or make worse any infections that you have.
• Get emergency help right away if you have any symptoms of a heart attack or stroke while using OPZELURA, including:
  • discomfort in the center of your chest that lasts for more than a few minutes, or that goes away and comes back
  • severe tightness, pain, pressure, or heaviness in your chest, throat, neck, or jaw
  • pain or discomfort in your arms, back, neck, jaw, or stomach
  • shortness of breath with or without chest discomfort
  • breaking out in a cold sweat
  • nausea or vomiting
  • feeling lightheaded
  • weakness in one part or on one side of your body
  • slurred speech
• Tell your healthcare provider right away if you have any signs and symptoms of blood clots during treatment with OPZELURA, including: swelling, pain or tenderness in one or both legs, sudden, unexplained chest or upper back pain, or shortness of breath or difficulty breathing.
• Tell your healthcare provider right away if you develop or have worsening of any symptoms of low blood cell counts, such as:  unusual bleeding, bruising, tiredness, shortness of breath or fever.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

The most common side effects of OPZELURA include: pain or swelling in your nose or throat (nasopharyngitis), diarrhea, bronchitis, ear infection, increase in a type of white blood cell counts (eosinophil), hives, inflamed hair pores (folliculitis), swelling of the tonsils (tonsilitis), and runny nose (rhinorrhea).

These are not all of the possible side effects of OPZELURA. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1‑800-FDA-1088. You may also report side effects to Incyte Corporation at 1-855-463-3463.
