Insights

Pharmaceutical Analyst

An analysis of the recent clinical trial results for upadacitinib shows a notable advancement in the treatment of moderate-to-severe atopic dermatitis (AD). Benchmarked against a competitor, dupilumab, the medication demonstrated a higher proportion of patients achieving significant skin clearance and itch relief. Understanding the patient-reported outcomes measures such as EASI and WP-NRS is critical for evaluating drug efficacy in dermatological conditions. Increased scores in these assessments may translate into better quality of life for patients, which can be a strong selling point for the drug's adoption in medical practice.

From a financial perspective, superior clinical outcomes can potentially lead to an increased market share for upadacitinib. It is important to consider the competitive landscape and how this drug's performance might influence payer and prescriber decisions, possibly affecting AbbVie's revenue stream in the AD market segment.

Medical Research Analyst

Given that the safety profile of upadacitinib aligns with previous studies while no new safety signals were observed, this consistency is reassuring for continued use. However, long-term data will be important to further understand the risk-benefit ratio, which is a pivotal factor in the adoption rate among patients and healthcare providers. In the context of adverse events, the comparison of nasopharyngitis incidence and serious AEs between upadacitinib and dupilumab provides vital information for risk assessment.

Furthermore, the study's open-label design might be less robust than a double-blind methodology, potentially introducing bias. It will be interesting to see if subsequent research corroborates these findings under more stringent trial conditions.

• Upadacitinib demonstrated superiority versus dupilumab in primary endpoint of simultaneous achievement of near complete skin clearance (EASI 90) and no to little itch (WP-NRS 0/1) at Week 16¹
• LEVEL UP, a Phase 3b/4 head-to-head study, compared upadacitinib to dupilumab for the treatment of adult and adolescent patients with moderate-to-severe atopic dermatitis who had inadequate response to systemic therapy or when use of those therapies was inadvisable¹
• The safety profile of upadacitinib was consistent with the profile in previous atopic dermatitis studies with no new safety signals identified during the 16-week period^1,2

NORTH CHICAGO, Ill., April 25, 2024 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced positive topline results from LEVEL UP, an open-label, efficacy assessor-blinded head-to-head Phase 3b/4 study that evaluated the efficacy and safety of upadacitinib (RINVOQ^®, 15 mg once daily starting dose and dose-adjusted based on clinical response) versus dupilumab (DUPIXENT^®, per its labeled dose) in adults and adolescents (≥12 years of age) with moderate-to-severe atopic dermatitis (AD) who had an inadequate response to systemic therapy or when use of those therapies was inadvisable.

"Even while receiving conventional treatments, many patients with atopic dermatitis still continue to live with significant itch and inflammatory skin symptoms that can profoundly impact their everyday lives," said Roopal Thakkar, M.D., senior vice president, chief medical officer, global therapeutics, AbbVie. "Results from this study show that patients with moderate-to-severe atopic dermatitis can strive for both little to no itch and clearer skin."

In the LEVEL UP study, upadacitinib showed superior efficacy versus dupilumab in the primary endpoint, demonstrating that a significantly higher proportion of patients simultaneously achieved both a 90% or greater reduction in Eczema Area and Severity Index (EASI 90) and a Worst Pruritus Numerical Rating Scale of 0 or 1 (WP-NRS 0/1) at Week 16 [(19.9% vs 8.9% for upadacitinib and dupilumab respectively, p<0.0001)].¹

The EASI is a clinically validated measure used to assess the severity and extent of atopic dermatitis, while the WP-NRS is an assessment tool that patients use to report the intensity of their pruritus daily (with 0 being 'no itch' and 10 being the 'worst imaginable itch').

Upadacitinib also showed superiority versus dupilumab for all ranked secondary endpoints, including the rapid onset of achieving near complete skin clearance and no to little itch. For the first two ranked secondary endpoints, the study showed that a significantly higher proportion of patients treated with upadacitinib:

• Achieved EASI 90 at Week 16 [(40.8% vs 22.5%, p<0.0001)].¹
• Achieved a WP-NRS of 0/1 at Week 16 [(30.2% vs 15.5%, p<0.0001)].^1,a

AbbVie plans to present results from the LEVEL UP study at a future medical congress.

The LEVEL UP study is the first head-to-head trial in atopic dermatitis assessing upadacitinib at a starting dose of 15 mg daily versus dupilumab at its labeled dose. Upadacitinib was initiated in adults and adolescents (≥12 years of age, weighing at least 40 kg) at 15 mg once daily (QD) and dose-escalated to 30 mg QD based on clinical response. Dupilumab was initiated at 600 mg, followed by 300 mg every other week (Q2W) in adults and adolescents weighing ≥60 kg; adolescents weighing less than 60 kg received an initial dose of 400 mg, followed by 200 mg Q2W.¹

"Too many patients are still not achieving optimal disease control in atopic dermatitis despite taking steps to manage their condition," said Jonathan Silverberg, M.D., Ph.D., MPH, professor of dermatology and director of clinical research at the George Washington University School of Medicine and Health Sciences. "Results from the LEVEL UP study highlight how treatment options such as upadacitinib can achieve high treatment goals in atopic dermatitis with combined measures of EASI 90 and NRS 0/1, not just itch resolution or just skin clearance."

The observed safety profile for upadacitinib in LEVEL UP was consistent with that observed in previous upadacitinib atopic dermatitis clinical studies.^1,2 No new safety signals were identified during the study period.¹ In Period 1, the most common adverse events (AE) reported were nasopharyngitis for both the upadacitinib and dupilumab group.¹ The rate of serious AEs (0.9%) was the same for both upadacitinib and dupilumab. There was one serious infection reported in the dupilumab group and none in the upadacitinib group.¹ No malignancies, adjudicated major adverse cardiac events, adjudicated venous thromboembolic events (VTEs) or treatment-emergent deaths were reported in either treatment group.¹

^[a] This endpoint was evaluated among patients with a baseline WP-NRS >1.

About Atopic Dermatitis 
Atopic dermatitis is a chronic, relapsing inflammatory condition characterized by a cycle of intense itching and scratching leading to cracked, scaly, oozing skin.^3,4 It affects up to an estimated 10% of adults and 24.6% of adolescents.^4-6 Between 20% and 46% of adults with atopic dermatitis have moderate-to-severe disease.⁷ The range of symptoms poses significant physical, psychological and economic burden on individuals impacted by the disease.^4,8

About LEVEL UP 
LEVEL UP is a Phase 3b/4, multi-center, randomized, open-label, efficacy assessor-blinded study, comparing the efficacy and safety of upadacitinib versus dupilumab in adult and adolescent (≥12 years of age, weighing at least 40 kg) patients with moderate-to-severe atopic dermatitis who had inadequate response to systemic therapy or when use of those therapies was inadvisable. The study comprises a 35-day screening period, a 16-week treatment Period 1 and a 16-week treatment Period 2. During Period 1, participants were randomly assigned in one of two groups to receive upadacitinib 15 mg QD or dupilumab as per its label. In Period 2, participants received upadacitinib as per protocol-defined criteria. The primary endpoint was the simultaneous achievement of a 90% or greater reduction in Eczema Area and Severity Index (EASI 90) and a Worst Pruritus Numerical Rating Scale of 0 or 1 (WP-NRS 0/1) at Week 16. Key ranked secondary endpoints included the achievement of EASI 90 at Week 16, and the achievement of a WP-NRS of 0/1 at Week 16 among those with a Baseline WP-NRS >1. The mean body surface area (BSA) among patients enrolled in the study was 38%, and 42% of patients had severe disease (vIGA-AD = 4) at baseline.

What is the most important information I should know about RINVOQ?
RINVOQ may cause serious side effects, including:

• Serious infections. RINVOQ can lower your ability to fight infections. Serious infections have happened while taking RINVOQ, including tuberculosis (TB) and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections. Your healthcare provider (HCP) should test you for TB before starting RINVOQ and check you closely for signs and symptoms of TB during treatment with RINVOQ. You should not start taking RINVOQ if you have any kind of infection unless your HCP tells you it is okay. If you get a serious infection, your HCP may stop your treatment until your infection is controlled. You may be at higher risk of developing shingles (herpes zoster).
• Increased risk of death in people 50 years and older who have at least 1 heart disease (cardiovascular) risk factor.
• Cancer and immune system problems. RINVOQ may increase your risk of certain cancers. Lymphoma and other cancers, including skin cancers, can happen. Current or past smokers are at higher risk of certain cancers, including lymphoma and lung cancer. Follow your HCP's advice about having your skin checked for skin cancer during treatment with RINVOQ. Limit the amount of time you spend in sunlight. Wear protective clothing when you are in the sun and use sunscreen.
• Increased risk of major cardiovascular (CV) events, such as heart attack, stroke, or death, in people 50 years and older who have at least 1 heart disease (CV) risk factor, especially if you are a current or past smoker.
• Blood clots: Blood clots in the veins of the legs or lungs and arteries can happen with RINVOQ. This may be life-threatening and cause death. Blood clots in the veins of the legs and lungs have happened more often in people who are 50 years and older and with at least 1 heart disease (CV) risk factor.
• Allergic reactions. Symptoms such as rash (hives), trouble breathing, feeling faint or dizzy, or swelling of your lips, tongue, or throat, that may mean you are having an allergic reaction have been seen in people taking RINVOQ. Some of these reactions were serious. If any of these symptoms occur during treatment with RINVOQ, stop taking RINVOQ and get emergency medical help right away.
• Tears in the stomach or intestines. This happens most often in people who take nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids. Get medical help right away if you get stomach-area pain, fever, chills, nausea, or vomiting.
• Changes in certain laboratory tests. Your HCP should do blood tests before you start taking RINVOQ and while you take it. Your HCP may stop your RINVOQ treatment for a period of time if needed because of changes in these blood test results.

Do not take RINVOQ if you are allergic to upadacitinib or any of the ingredients in RINVOQ. See the Medication Guide or Consumer Brief Summary for a complete list of ingredients.

What should I tell my HCP BEFORE starting RINVOQ?
