The primary aim of the pilot (SAPS) protocol is to determine the feasibility and utility of implementing the provisional design of the full scale TOM trial (e.g., the six month treatment period, the impact of the smoking cessation intervention).
There is no active hypothesis for the Vanguard Protocol.
|Condition or disease||Intervention/treatment||Phase|
|Asthma||Drug: Fluticasone 250 mg/salmeterol 50 mg Drug: Montelukast 10mg Drug: Theophylline 400 mg Drug: ipratropium||Phase 4|
The protocol is a small scale pilot of the full-scale TOM trial, and it will utilize a placebo design and incorporates 4 treatment arms. In the Vanguard Protocol all participants are to complete a 4 week run-in with Advair 100/50, followed by randomization to 1 of 4 arms of study treatment. The 4 drug treatment combinations are (2 inhalers, 2 pills):
- Advair 250/50, Placebo, Placebo, Placebo
- Advair 100/50 and montelukast, Placebo, Placebo
- Advair 100/50 and theophylline, Placebo, Placebo
- Advair 100/50 and ipratropium, Placebo, Placebo The 24 week treatment phase will be followed by a 4 week washout period on Advair 100/50. There is no crossover.

- Asthma Control Test [ Time Frame: Outcome measures were determined at the initial visit, at randomization following a wash-in period of 1 month, monthly for 24 weeks and0 that a follow-up visit 1 month off study drug. Mean scores over the 24 weeks of treatment were compared. ]The primary symptomatic measure, the Asthma Control Test (ACT), has been shown to be valid for measuring poor asthma control in asthmatic children and non-smoking adults. The ACT is a tool developed by Nathan and collaborators a decade ago for evaluating asthma control. It consists of five questions with five possible answers each. A maximum score of 25 points indicates complete asthma control. A score between 20 and 24 represents partially controlled asthma, while a score 19 or below indicates poorly controlled asthma and a score <16 indicates uncontrolled asthma. The minimally important clinical difference has been determined to be 3.
- The Asthma Symptom Utility Index(AUSI) [ Time Frame: Outcome measures were determined at the initial visit, at randomization following a wash-in period of 1 month, monthly for 24 weeks and0 that a follow-up visit 1 month off study drug. Mean scores over the 24 weeks of treatmen ]The Asthma Symptom Utility Index (AUSI), an important secondary outcome in the proposed full-scale TOM Trial, has also been shown to be useful in tracking the frequency and severity of asthma-related symptoms in non-smoking asthmatics.
- Physiologic Measures Were Determined at the Initial Visit, at Randomization Following a wash-in Period of 1 Month, Monthly for 24 Weeks and0 That a Follow-up Visit 1 Month Off Study Drug. Mean Scores Over the 24 Weeks of Treatment Were Compared. [ Time Frame: At each visit ]Physiologic measures of FEV1, FVC and FEV1/FVC ratio
