Incyte Announces Long-Term Extension Data from Phase 3 TRuE-V Program Demonstrating Long-Term Safety and Durability of Response of Opzelura® (Ruxolitinib) Cream in Vitiligo

- Patients achieving a high level of facial repigmentation (≥F-VASI90) at Week 52 maintained durable response one year following withdrawal of treatment

- Continued treatment with Opzelura for up to two years resulted in sustained facial repigmentation and further improvements in facial and total body repigmentation

- Data featured as oral presentations in two late-breaking abstract sessions at the 2023 American Academy of Dermatology (AAD) Annual Meeting

Incyte (Nasdaq:INCY) today announced new 104-week results from the pivotal Phase 3 TRuE-V clinical trial program evaluating Opzelura^® (ruxolitinib) cream 1.5% in patients 12 years of age and older with nonsegmental vitiligo, a chronic autoimmune disease characterized by depigmentation of skin. These data were presented today in two late-breaking oral presentations (Session: S025 – Late Breaking Research: Session 1) at the 2023 American Academy of Dermatology (AAD) Annual Meeting, held from March 17-21 in New Orleans.

The 104-week long-term extension (LTE) data build on the positive 52-week TRuE-V1 and TRuE-V2 results previously announced and published in The New England Journal of Medicine.

“The results presented today at AAD are significant because they provide important long-term efficacy and safety data for nonsegmental vitiligo patients treated with Opzelura,” said Jim Lee, M.D., Ph.D., Group Vice President, Inflammation & Autoimmunity, Incyte. “The data, which showed improvements in both facial and total body repigmentation with continued treatment, further our understanding of the long-term benefits of Opzelura as a safe and meaningful pharmacologic treatment option for vitiligo patients.”

The LTE evaluated TRuE-V1 and TRuE-V2 study participants from Weeks 52 to 104 in two separate cohorts based on patients who achieved a complete or almost complete response by Week 52. In the cohort of patients who achieved complete or almost complete facial repigmentation (≥F-VASI90, Cohort A), patients were randomized in a double-blind fashion to receive Opzelura twice daily (BID) or vehicle (i.e., Opzelura withdrawal) through Week 104 to evaluate time to relapse (defined as <F-VASI75) and time to maintain ≥F-VASI90 response; time to regain F-VASI75 and F-VASI90 response after relapse (with reinitiation of Opzelura treatment) was also evaluated. In the cohort of patients who did not achieve complete or almost complete facial repigmentation (<F-VASI90, Cohort B), all patients were continued on Opzelura BID to evaluate long-term efficacy and safety.

Key findings from Cohort A:

• Many patients who achieved a high level of facial repigmentation (≥F-VASI90) in TRuE-V1/TRuE-V2 were able to maintain durable response for one year after discontinuing Opzelura treatment.
  • Approximately 29% of patients randomized to the withdrawal arm (i.e., applying vehicle cream) relapsed (<F-VASI75) during the extension period (through Week 104).
  • Among patients who relapsed (<F-VASI75) in the withdrawal arm, 75% of patients regained ≥F-VASI75 once treatment with Opzelura was reinitiated (median 12 weeks) and 69% of patients regained ≥F-VASI90.
• For those continuing Opzelura treatment, approximately 62% of patients who achieved ≥F-VASI90 at Week 52 maintained response for one year with ongoing Opzelura treatment.
• Opzelura was well tolerated with no serious treatment-related adverse events through Week 104. Mild or moderate treatment-related adverse events among patients in the Opzelura arm included application site dermatitis, application site rash and hyperlipidemia.

Key findings from Cohort B:

• In patients who did not achieve near complete facial repigmentation (<F-VASI90) at Week 52 and continued treatment with Opzelura, improvements in facial and total body repigmentation, as shown by greater proportions of patients reaching F-VASI75 and T-VASI50, were observed through Week 104.
  • For patients treated with Opzelura from Day 1 in the parent studies (TRuE-V1 and TRuE-V2), the percentage who achieved F-VASI75 at Week 104 more than doubled (66%) compared to Week 52 (31%), and approximately 34% attained F-VASI90 at Week 104.
  • Additionally, T-VASI50 was achieved at Week 104 by 64% of TRuE-V1 and TRuE-V2 patients applying Opzelura since Day 1, increasing from 43% at Week 52.
• Opzelura was well tolerated with no serious treatment-related adverse events through Week 104. All treatment–related adverse events in the Opzelura arm were mild or moderate, the most common being application site pruritus.

“I am extremely encouraged by these data, which show continued improvements in facial and total body repigmentation over two years of treatment with Opzelura,” said David Rosmarin, M.D., Chair, Department of Dermatology at Indiana University School of Medicine. “Vitiligo is a chronic condition and these results demonstrate the long-term potential of this medical treatment for people with vitiligo who are interested in repigmentation.”

About Vitiligo

Vitiligo is a chronic autoimmune disease characterized by depigmentation of skin that results from the loss of pigment-producing cells known as melanocytes. Overactivity of the JAK signaling pathway is believed to drive inflammation involved in the pathogenesis and progression of vitiligo. In the United States, more than 1.5 million people are diagnosed with vitiligo¹. The overall prevalence of the condition is estimated to be approximately 2-3 million², with the majority of patients (approximately 85%) suffering from nonsegmental vitiligo³. Vitiligo can occur at any age, although many patients with vitiligo will experience initial onset before the age of 30⁴.

About TRuE-V

The TRuE-V clinical trial program includes two Phase 3 studies, TRuE-V1 (NCT04052425) and TRuE-V2 (NCT04057573), evaluating the safety and efficacy of Opzelura in patients with vitiligo. Each study enrolled approximately 300 patients (age ≥12 years) who have been diagnosed with nonsegmental vitiligo.

About Opzelura^® (ruxolitinib) Cream 1.5%

Opzelura, a novel cream formulation of Incyte’s selective JAK1/JAK2 inhibitor ruxolitinib, approved by the U.S. Food & Drug Administration for the topical treatment of nonsegmental vitiligo in patients 12 years of age and older, is the first and only treatment for repigmentation approved for use in the United States. Opzelura is also approved in the U.S. for the topical 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. Use of Opzelura in combination with therapeutic biologics, other JAK inhibitors, or potent immunosuppressants, such as azathioprine or cyclosporine, is not recommended.

On February 24, 2023, Incyte announced that the European Medicines Agency (EMA) Committee for Medicinal Products for Human Use (CHMP) issued a positive opinion recommending the approval of ruxolitinib cream for the treatment of non-segmental vitiligo with facial involvement in adults and adolescents from 12 years of age. The marketing authorization application (MAA) and CHMP opinion are now under review by the European Commission, which has the authority to grant centralized marketing authorizations for medicinal products in the EU.

Incyte has worldwide rights for the development and commercialization of ruxolitinib cream, marketed in the United States as Opzelura. In April 2022, Incyte entered into a strategic alliance agreement with Maruho Co., Ltd. for the development, manufacturing and exclusive commercialization of ruxolitinib cream for treatment of autoimmune and inflammatory dermatology indications in Japan.

Opzelura is a trademark of Incyte.

IMPORTANT SAFETY INFORMATION

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

OPZELURA may cause serious side effects, including:

Serious Infections: OPZELURA 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 due to any reason (all causes): Increased risk of death has happened in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and are taking a medicine in the class of medicines called 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. Lymphoma and other cancers have happened in people taking a medicine in the class of medicines called JAK inhibitors by mouth. People taking JAK inhibitors by mouth have a higher risk of certain cancers including lymphoma and lung cancer, especially if they are a current or past smoker. Some people have had skin cancers while using OPZELURA. Your healthcare provider will regularly check your skin during your treatment with OPZELURA. Limit the amount of time you spend in the sunlight. Wear protective clothing when you are in the sun and use a broad-spectrum sunscreen.

Increased risk of major cardiovascular events: Increased risk of major cardiovascular events such as heart attack, stroke, or death have happened in people 50 years of age and older who have at least 1 heart disease (cardiovascular) risk factor and taking a medicine in the class of medicines called JAK inhibitors by mouth, especially in current or past smokers.

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. Blood clots in the vein of the legs (deep vein thrombosis, DVT) and lungs (pulmonary embolism, PE) have happened more often in people who are 50 years of age and older and with at least 1 heart disease (cardiovascular) risk factor taking a medicine in the class of medicines called JAK inhibitors by mouth.

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 had an infection that does not go away or keeps coming back
