| Scientific title | The effect of Der p 1 inhalation on bronchial responsiveness to inhaled cat allergen in asthmatics sensitised to cat but not to house dust mite |
| Study objectives | To detect whether bronchial responsiveness to cat allergen, in a subject sensitised to cat, but not dust mite, may be enhanced by the presence of Dermatophagoides pteronyssinus 1 (Der p 1), a cysteine peptidase allergen. |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Asthma |
