Title: Asthma Clinical Research Network (ACRN) Trial - Best Adjustment Strategy for Asthma in Long Term (BASALT)
Brief Summary: Asthma can be effectively controlled using inhaled corticosteroid medication. Treatment with inhaled corticosteroids often requires periodic adjustments to medication dosing and frequency levels. This study examines whether it is more beneficial to adjust corticosteroid treatment based on asthma symptoms and/or biomarkers of lung function versus standard medical guidelines.


Options:
A: Inclusion Criteria:

* Diagnosis os asthma, taking 200-1000mcg budesonide or equivalent per day
* FENO greater than 30ppb on treatment

Exclusion Criteria:

* Recent RTI or prednisolone
* Smoking within 1 year or 10 pack years
* ABPA, COPD, bronchiectasis
B: Inclusion Criteria for BASALT and TALC Studies:

* Clinical history consistent with asthma
* Forced expiratory volume in one second (FEV1) greater than 40% of predicted value
* Asthma confirmed by one of the following two criteria:

  1. Beta-agonist reversibility to 4 puffs albuterol of at least 12% OR
  2. Methacholine provocative concentration at 20% (PC20) FEV1 of 8 milligrams per millimeter (mg/mL) or less when not on an inhaled corticosteroid, or 16 mg/mL or less when on an inhaled corticosteroid
* Need for daily controller therapy (i.e., inhaled corticosteroids, leukotriene modifiers, and/or long-acting beta-agonists) based on one or more of the following criteria:

  1. Received prescription for or used asthma controller within the 12 months prior to study entry OR
  2. Experienced symptoms for more than twice a week and not on asthma controller
* If on inhaled steroids (any drug at any dose not exceeding the equivalent of 1000 micrograms (mcg) of fluticasone daily), participant must have been on a stable dose for at least 2 weeks prior to study entry

* 75% compliance with recording peak flow measurements and symptoms in a symptom diary during the last 2 weeks of the adherence testing period
