|Official Title:||An Open-Label, Dose-Escalating, Study to Evaluate the Safety, Efficacy and Tolerability of Oral Nadolol for the Treatment of Adults With Mild Asthma|
|Study Start Date :||January 2007|

Experimental: Open Label treatment with oral Nadolol
Dose escalation through 1.25mgs, 2.5mgs, 5.0mgs, 10mgs, 20mgs, and 40mgs of nadolol at 2 week intervals as tolerated.
Nadolol, oral taken daily, doses will be escalated every two weeks over 13 weeks following a 2 week run-in.

- Mean Daily Dose at Study Termination Across Participants [ Time Frame: Baseline to end of study (105 days) ]The outcome measure describes the mean daily dose achieved by the subjects at study termination. This data includes one subject who terminated early, having reached 2.5mgs and subsequently reducing to 1.25mgs prior to dropping out.
- Daily Dose at Study Termination Across Participants [ Time Frame: Baseline to end of study (105 days) ]The outcome measure describes the final daily dose achieved by the subjects in this study. The subjects described below who finished on less than the highest dose (i.e., 1.25, 5, and 10mgs) had all been down-titrated one dose (i.e., from 2.5, 10, and 20mgs) prior to completing the study on the dose reported.
- Change in Airway Hyper-reactivity Compared to Baseline (Change in PC20 Doubling Dose by Methacholine Challenge) [ Time Frame: Baseline to end of study (105 days) ]Bronchoprovocation assessment was done by doubling doses of methacholine in accordance with the methodology recommended by the American Thoracic Society in the official policy statement adopted by the ATS Board of Directors, July 1999 (Guidelines for Methacholine and Exercise Challenge Testing-1999).
- Percent Change in FEV1% Predicted From Baseline to End of Study [ Time Frame: Baseline to end of study (105 days) ]
- Change in Asthma Control Questionnaire (ACQ) Score Compared to Baseline [ Time Frame: Baseline to end of study (105 days) ]In the E.F. Juniper Asthma Control Questionnaire, a lower number reflects better control of asthma symptoms. A positive change in ACQ score reflects a reduction in control compared to baseline; conversely, a negative change in ACQ score reflects an increase in control compared to baseline. The ACQ has 7 questions (the top scoring 5 symptoms, FEV1% pred. and daily rescue bronchodilator use). Patients are asked to recall how their asthma has been during the previous week and to respond to the symptom and bronchodilator use questions on a 7-point scale (0=no impairment, 6= maximum impairment). Clinic staff score the FEV1% predicted on a 7-point scale. The questions are equally weighted and the ACQ score is the mean of the 7 questions and therefore between 0 (totally controlled) and 6 (severely uncontrolled).
