– New findings in human sensory neurons highlight role of IL-13 in amplifying itch and lebrikizumab’s role in inhibiting itch signals in atopic dermatitis
– Lebrikizumab Phase 3 program is currently enrolling adult and adolescent patients with moderate-to-severe atopic dermatitis
MENLO PARK, Calif.–(BUSINESS WIRE)–Dermira, Inc. (NASDAQ: DERM), a biopharmaceutical company dedicated to bringing biotech ingenuity to medical dermatology by delivering differentiated, new therapies to the millions of patients living with chronic skin conditions, today announced that new scientific findings highlighting the role of interleukin-13 (IL-13) in amplifying itch and the role lebrikizumab plays in reducing itch, will be presented at the 10th World Congress on Itch taking place November 17-19 in Sydney, Australia.
Itch is defined as an unpleasant sensation causing the desire to scratch the surface of the skin. Chronic itch affects approximately one-fifth of the global population and can have a significant impact on a person’s quality of life. Itch is often associated with sleep disorders, depression and anxiety and is cited as one of the most burdensome aspects of atopic dermatitis, as underscored during a recent Patient-Focused Drug Development meeting.
IL-13 is believed to be a central pathogenic mediator that drives multiple aspects of the pathophysiology underlying the range of signs and symptoms of atopic dermatitis by promoting type 2 inflammation and mediating its effects on tissue, resulting in skin barrier dysfunction, itch, skin thickening and infection.
Key Research Findings
In laboratory experiments, cultured human sensory neurons were stimulated with IL-13 and subsequently introduced to several common itch-inducing agents (pruritogens), including histamine, serotonin and BAM8-22. The experiments demonstrated that IL-13 directly interacts with human sensory neurons, enhancing the itch induced by these itch-inducing agents.
When lebrikizumab was introduced, it significantly inhibited these potentiated itch signals to known pruritogens, demonstrating that lebrikizumab has the potential to block enhanced itch signals in inflammatory skin conditions such as atopic dermatitis. This finding supports the results observed in Dermira’s Phase 2b dose-ranging study evaluating lebrikizumab in patients with moderate-to-severe atopic dermatitis, who reported improvements in itch symptoms as early as day two of treatment.
The findings will be submitted for publication in a peer-reviewed journal.
“People suffering from chronic itch associated with a host of dermatologic diseases often cite it as the most debilitating symptom,” said Luis Peña, chief development officer of Dermira. “We believe these findings support our understanding of the role of lebrikizumab in reducing itch, helping to explain the improvement in itch observed in atopic dermatitis patients treated with the investigational therapy in our Phase 2b study.”
Lebrikizumab is a novel, investigational, monoclonal antibody designed to bind IL-13 with very high affinity, specifically preventing the formation of the IL-13Rα1/IL-4Rα heterodimer complex and subsequent signaling, thereby inhibiting the biological effects of IL-13 in a targeted and efficient fashion.
The findings on itch will be presented by Ferda Cevikbas, Ph.D., director of research at Dermira, on November 19, 2019 during a session titled, Concurrent Session 2: New receptors, channels and pathways for itch. Dr. Cevikbas is also serving as co-chair of the session.
Dr. Cevikbas is a noted expert in the pathophysiology of itch, having spent much of her career at the University of California, San Francisco, where she studied the differences and similarities between itch and pain. Prior to joining Dermira, she worked with a team of researchers at a biotechnology company exploring the mechanism of action for research compounds in inflammation and itch. Dr. Cevikbas is trained in dermatology and neuroscience.
“IL-13 has long been viewed as an important target in atopic dermatitis,” said Dr. Cevikbas. “For the first time, IL-13 has been investigated in translational neuroscience studies in human sensory neurons to understand its role in chronic itch and the ability of lebrikizumab to block the effects of neuroactive IL-13. This translational work will inform future research and enhance our understanding of chronic itch in atopic dermatitis.”
About Atopic Dermatitis
Atopic dermatitis is the most common and severe form of eczema, a chronic inflammatory condition that can present as early as childhood and continue into adulthood. A moderate-to-severe form of the disease is characterized by a range of signs and symptoms, including rashes on the skin that often cover much of the body, as well as intense, persistent itching. The condition can have a negative impact on patients’ mental and physical functioning, limiting their daily activities and health-related quality of life. Patients with moderate-to-severe atopic dermatitis have reported a larger impact on quality of life than patients with psoriasis.
Lebrikizumab is a novel, investigational, monoclonal antibody designed to bind IL-13 with very high affinity, specifically preventing the formation of the IL-13Rα1/IL-4Rα heterodimer complex and subsequent signaling, thereby inhibiting the biological effects of IL-13 in a targeted and efficient fashion.
