Research in PNAS by Hydra shows that TRP ion channel drug can treat allergy-induced asthma
May 19, 2009Hydra Biosciences, Inc., a biotech company developing novel ion channel drugs, today announced that research published by Hydra Biosciences scientists and collaborators at Yale University for the first time identified the ion channel TRPA1 as playing an essential role in allergic asthma and demonstrated that Hydra's TRPA1 antagonist HC-030031 effectively treated allergic asthma in mice. The paper, titled "A sensory neuronal ion channel essential for airway inflammation and hyperreactivity in asthma," will appear this week in Proceedings of the National Academy of Sciences (PNAS).
"This study demonstrates - for the first time - that TRPA1 plays a key role in asthma," said Sven-Eric Jordt, Ph.D, of Yale University, the paper's lead author and a member of the Hydra Biosciences Scientific Advisory Board. "These data have extraordinary implications for treating asthma, and a number of other inflammatory conditions, in a completely new way, as we believe that blocking TRPA1 may prevent the infiltration of the lung by the inflammatory cells responsible for asthma symptoms such as wheezing and mucus overproduction."
This breakthrough research could open a completely new avenue of drug treatment for asthma. There has been a dramatic increase in the number of asthma cases reported in recent decades. Scientists know that asthma involves an immune response to inhaled allergens that results in inflammation, mucus secretion and bronchial constriction. But the limited efficacies of therapies aimed at the immune system suggest that additional physiological mechanisms may be involved in asthmatic inflammation. Targeting the TRPA1 ion channel could represent a therapeutic breakthrough in the treatment of allergic asthma.
Hydra Biosciences, a leader in the field of TRP drug discovery, is currently developing a novel TRPA1 inhibitor and is advancing this drug candidate into human clinical trials within 12 months.
In the study, the research team evaluated the ability of a TRPA1 antagonist to inhibit TRPA1 function in a murine model of asthma. The antagonist successfully alleviated inflammation, airway constriction, and mucus overproduction associated with allergic asthma. Genetic deletion of TRPA1 in mice elicited similar effects, confirming the central role of TRPA1 in asthma.
"The finding that TRPA1 plays an essential role in allergic asthma is revolutionary, and suggests that a drug candidate that successfully modulates this ion channel has the potential to treat asthma and other allergic inflammatory conditions," said Russell Herndon, Chief Executive Officer, Hydra. "Due to our experience and expertise with TRP ion channels, Hydra is on the leading edge in this field, and we are aggressively advancing a TRPA1 drug candidate into clinical studies within 12 months."

Allergic Asthma Current Events and Allergic Asthma News RSSPreventing allergies
Allergic diseases are becoming increasingly common in Western industrialized countries. As there is still no etiologically based treatment of allergic asthma, hay fever, or atopic eczema, the prevention of these diseases is a matter of special importance.
Asthma and other allergies tied to absence of specialized cells
When it comes to allergies, both the problem and the solution are found within us. Our immune systems respond to foreign substances with an arsenal of cells.
Handling pesticides associated with greater asthma risk in farm women
New research on farm women has shown that contact with some commonly used pesticides in farm work may increase their risk of allergic asthma.
Fight against hay fever and other allergies helped by new immune system discovery
A mechanism which can lead to hay fever and other allergic reactions, by preventing the immune system from regulating itself properly, has been discovered by scientists.
Scientists puzzled by severe allergic reaction to cancer drug in the middle Southern US
A patient's expectations about the side effects of chemotherapy usually focus on nausea, hair loss, fatigue and other side effects. Worries about severe allergic reactions to their therapy is usually not a concern.
Study indicates different treatment may be needed for infection-related breathing problems
New research suggests that different treatments may be needed for chronic asthma, depending on whether it results from allergies or lung infections.
UT Southwestern tests new asthma medicine targeting vulnerable inner-city children
UT Southwestern Medical Center is one of a handful of top research institutions evaluating a promising new medication researchers hope can reduce the severity and frequency of asthma attacks in inner-city children, a population known to have a high prevalence of severe asthma.
Self-Hypnosis Was Found To Be Effective On Hay Fever Symptoms
A group of researchers of the University of Basel has performed a randomized controlled trial on the use of self-hypnosis (which was likely to induce relaxation) on a hay fever symptoms. Many people suffer from hay fever symptoms. Hypnosis has proved to be a useful adjunct in the treatment of conditions where allergic phenomena have an important role.: Randomised parallel group study over an observation period of two consecutive pollen seasons. Outcome data include nasal flow under hypnosis, pollinosis symptoms from diaries and retrospective assessments, restrictions in well-being and use of anti-allergic medication. We investigated 79 patients with a mean age of 34 years (range 19-54 years;
White blood cell plays key role in body's excessive repair response to asthma - Airway scarring can be disrupted by targeting eosinophils
Researchers in London and Montreal report today that they have discovered an important link in the development of the body's response to allergic asthma. They have found that one type of white blood cell, an eosinophil, which was known to cause inflammation of lung airways, is also responsible for driving the process which leads to an excessive 'repair response' by the body. The response, which is called airway remodelling, causes structural changes in the airway walls and can sometimes lead to permanent scarring and narrowing of the airways, resulting in worse and repeated asthma episodes for sufferers. The team of scientists from Imperial College London, the Royal Brompton Hospital, Londo
