TRPV1 x JAK2 x JAK1 x JAK3

This is a Phase 1, randomized, double-blinded, placebo controlled study. The study consists of 4 parts: Part 1 is a single ascending dose (SAD) study in healthy volunteers; Part 2 is a multiple ascending dose (MAD) study in subjects with stable, mild asthma; Part 3 is a repeat dose in patients with moderate to severe asthma and Part 4 is a repeat dose in patients with COPD.

Asthma is a long term disease of the lungs. In asthma patients the sensitive airway tubes narrow in reaction to something that irritates the airways such as allergens or environmental pollutants. There is currently no cure for asthma and new medicines or combinations of medicines are needed that will be of benefit to patients particularly those with a more severe disease.
Activation of certain signal molecules inside the lung cells may participate in the development of asthma and the response to allergens. Blocking these signal molecules specifically with medicines might therefore be beneficial in the treatment of asthma. In this study we want to test a new medicine that specifically targets a subset of signal molecules that are associated with the allergen response in the lung. In particular, we want to test this medicine on cells obtained from the lungs of asthma patients. Understanding the effects of this new medicine on these asthmatic lung cells will give vital information on how this new medicine works before we can test it in asthma patients.
