News Release - April 1, 2016
Regeneron and Sanofi Announce Positive Dupilumab Topline Results from Two Phase 3 Trials in Inadequately Controlled Moderate-to-Severe Atopic Dermatitis Patientsdupilumab is first systemic therapy to show positive Phase 3 results in patients with moderate-to-severe atopic dermatitis, a serious, chronic inflammatory skin disease marked by widespread rash, itching and associated psychosocial comorbidities
U.S. regulatory submission for dupilumab planned for Q3 of 2016
TARRYTOWN, N.Y and PARIS, April 1, 2016 -- (Healthcare Sales & Marketing Network) -- Regeneron Pharmaceuticals, Inc. (REGN) and Sanofi today announced that two placebo-controlled Phase 3 studies evaluating investigational dupilumab in adult patients with inadequately controlled moderate-to-severe atopic dermatitis (AD) met their primary endpoints. In the studies, known as LIBERTY AD SOLO 1 and SOLO 2, treatment with dupilumab as monotherapy significantly improved measures of overall disease severity, skin clearing, itching, quality of life, and mental health.
"These are the first Phase 3 studies of a systemic therapy to demonstrate a significant improvement in moderate-to-severe atopic dermatitis, a chronic, debilitating inflammatory disease that impacts over one million Americans," said George D. Yancopoulos, M.D., Ph.D., Chief Scientific Officer of Regeneron and President of Regeneron Laboratories. "These data provide strong evidence that the IL-4 and IL-13 signaling pathway is a fundamental driver of inflammation in atopic dermatitis. dupilumab is the first in a new class of immunotherapies – in these 16 week trials, dupilumab blocked the aberrant activation of this pathway, resulting in significant efficacy without evidence of immune-suppressing side effects. We continue to evaluate the role of IL-4 and IL-13 signaling in related inflammatory conditions, including asthma and nasal polyposis, where we have ongoing dupilumab clinical development."
"There are no approved systemic therapies in the U.S. for people with moderate-to-severe atopic dermatitis, underscoring the clear unmet need. These results may bring new hope to atopic dermatitis patients, many of whom have suffered for years," said Elias Zerhouni, M.D., President, Global R&D, Sanofi. "In the U.S., where dupilumab in AD has been granted Breakthrough Therapy designation by the U.S. FDA, we plan to submit a regulatory application in the third quarter of this year and will work to bring this innovative therapy to patients as quickly as possible."
A total of 1,379 adult patients with moderate-to-severe AD were enrolled in the identically-designed SOLO 1 and SOLO 2 trials. Patients were enrolled if they were not adequately controlled with topical medications, or if topical treatment was not medically advisable. All patients were assessed via the 5-point Investigator's Global Assessment (IGA) scale, ranging from 0 (clear) to 4 (severe); entry criteria required a baseline score of 3 or 4. Patients were also assessed using the Eczema Area and Severity Index (EASI) and other measures. Patients were randomized into one of three treatment groups: dupilumab 300 mg subcutaneously once per week, dupilumab 300 mg subcutaneously every two weeks, or placebo for 16 weeks following an initial dupilumab loading dose of 600 mg subcutaneously, or placebo. Results at 16 weeks included the following:
- For SOLO 1 and SOLO 2, respectively, 37 and 36 percent of patients who received dupilumab 300 mg weekly, and 38 and 36 percent of patients who received dupilumab 300 mg every two weeks, achieved clearing or near-clearing of skin lesions (IGA 0 or 1), compared to 10 and 8.5 percent with placebo (p less than 0.0001). This was the primary endpoint of the study in the U.S.
- For SOLO 1 and SOLO 2, respectively, the percent improvement in EASI from baseline was 72 and 69 percent in patients who received the 300 mg weekly dose, and 72 and 67 percent for patients who received dupilumab 300 mg every two weeks, compared to 38 and 31 percent for placebo (p less than 0.0001).
- For SOLO 1 and SOLO 2, respectively, 52.5 and 48 percent of patients who received dupilumab 300 mg weekly, and 51 and 44 percent of patients who received dupilumab 300 mg every two weeks, achieved EASI-75 compared to 15 and 12 percent with placebo (p less than 0.0001). This was the key secondary endpoint in the US and one of the primary endpoints in the EU.
More detailed results from SOLO 1 and SOLO 2 will be submitted for presentation at a future medical congress.
The U.S. Food and Drug Administration (FDA) granted dupilumab Breakthrough Therapy designation in AD in November 2014. dupilumab is currently under clinical development and its safety and efficacy have not been fully evaluated by any regulatory authority.
The LIBERTY AD Phase 3 clinical program consists of five trials of patients with moderate-to-severe AD at sites worldwide.
About Atopic Dermatitis
Atopic dermatitis – a serious form of eczema – is a chronic inflammatory disease characterized by itchy, inflamed skin that can be present on any part of the body. Though symptoms appear externally, atopic dermatitis is characterized by underlying systemic inflammation. Atopic dermatitis affects approximately 7-8 million adults in the U.S. and 1-3 percent of adults worldwide. Based on a survey of 200 physicians, there are approximately 1.6 million moderate-to-severe diagnosed and treated patients in the U.S. with uncontrolled disease. About 70 percent of people with atopic dermatitis have a family history of other common atopic diseases, such as asthma or hay fever. The intense itching, scratching and skin damage associated with the disease can sometimes lead to infections, caused by bacteria, such as Staphylococcus aureus. In addition, the physical manifestations of the disease can lead to anxiety, depression, and feelings of social isolation.
