Investigators
Eligibility Criteria
Inclusion Criteria
- •Asthma patients will be selected using the following inclusion criteria:
- •Age 18\-50 years
- •History of episodic chest tightness and wheezing
Exclusion Criteria
- •Potential subjects who meet any of the following criteria will be excluded from participation in the study:
- •Women who are pregnant, lactating or have a positive urine pregnancy test at baseline visit
- •Participation in any clinical investigational drug treatment protocol within the preceding 5 half\-lives of the drug (or 12 weeks if the half life is unknown) before the screening visit
- •Concomitant disease or condition which could interfere with the conduct of the study, or for which the treatment might interfere with the conduct of the study, or which would, in the opinion of the investigator, pose an unacceptable risk to the patient
- •Furthermore the following additional exclusion criteria will be used in part 2 of the study:
- •RV16 titre \> 1:8 in serum, measured at screening (visit 1\) and also at Rhinovirus inoculation visit
- •History of clinical significant hypotensive episodes or symptoms of fainting, dizziness, or light\-headedness
- •History of an asthma exacerbation within the last 6 weeks prior to the study
- •Has had any acute illness, including a common cold, within 4 weeks prior to visit 1
- •Close contact with young children or with any immunosuppressed patients
