Sanofi and Regeneron Pharmaceutical announce Start of Phase 3 Study of Dupilumab in patients with Atopic Dermatitis
Monday, October 20, 2014
Sanofi and Regeneron Pharmaceuticals, Inc. today announced that the first patients have been dosed in a Phase 3 clinical study of dupilumab, an investigational therapy that blocks IL-4 and IL-13 signaling, in adults with moderate-to-severe atopic dermatitis (AD) that is not adequately controlled with topical AD medications.
LIBERTY AD CHRONOS, the first trial in the Phase 3 clinical program for dupilumab, is a randomized, double-blind, placebo-controlled, multi-national study with the primary objective of demonstrating the efficacy of dupilumab in adults with moderate to severe AD when administered concomitantly with topical corticosteroids through 16 weeks. Secondary objectives of the study will evaluate the long-term safety and efficacy of dupilumab up to 52 weeks. The trial will enroll approximately 700 adult patients.
“Moderate-to-severe atopic dermatitis is a serious disease characterized by severe itching, sleep disturbances and widespread rash, and existing treatment options have limited efficacy,” said Donald Y. M. Leung, MD, PhD, a member of the LIBERTY AD Clinical Trials Steering Committee and Head of the Division of Pediatric Allergy and Immunology at National Jewish Health in Denver, CO. “This Phase 3 program will evaluate if blocking IL-4 and IL-13, two key cytokines in the Th2 inflammatory pathway, may provide a potential new approach for this chronic, difficult-to-manage disease.”
The LIBERTY AD Phase 3 clinical program will consist of at least five trials of patients with moderate-to-severe AD at sites worldwide. For more information on the LIBERTY AD CHRONOS study, please

About the IL-4/IL-13 Pathway and Atopic Dermatitis
Moderate-to-severe atopic dermatitis, a serious, chronic form of eczema, is a systemic inflammatory disease characterized by an allergic response driven by a subset of immune cells called Type 2 helper T cells, or Th2 cells. IL-4 and IL-13 are key cytokines that are required for the initiation and maintenance of this Th2 immune response.
Moderate-to-severe forms of atopic dermatitis can be characterized by pronounced pruritus (itch), cutaneous dryness, and skin lesions marked by redness, infiltration/papulation, crusting/oozing, and lichenification (skin thickening), with periods of lesion exacerbation. Intense itching, scratching, and skin damage can lead to secondary infections. Atopic dermatitis is often associated with other inflammatory disorders such as asthma. Moderate-to-severe atopic dermatitis can negatively impact patients'' lives and is associated with a high burden to society in terms of direct costs of medical care and prescription drugs and loss of productivity.
