A Pilot Study to Determine the Feasibility and Utility of Implementing of the Full Scale TOM Trial (SAPS)

2 gennaio 2019 aggiornato da: Joe Ramsdell, University of California, San Diego

SAPS:Smoking Asthmatics Pilot Study:

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.

Descrizione dettagliata

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.

Misura Descrizione
Lasso di tempo
Asthma Control Test
Lasso di tempo: Outcome measure was assessed at the initial visit, at randomization following a wash-in period of 1 month, monthly for 24 weeks and at follow-up visit 1 month off study drug. Median 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.
Outcome measure was assessed at the initial visit, at randomization following a wash-in period of 1 month, monthly for 24 weeks and at follow-up visit 1 month off study drug. Median scores over the 24 weeks of treatment were compared.

The Asthma Symptom Utility Index (ASUI)

The Asthma Symptom Utility Index (ASUI), 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. ASUI is a brief, interviewer-administered, patient preference-based scale assessing frequency and severity of selected asthma-related symptoms and treatment side effects. 11 items are reviewed, with 2-week recall to assess four symptoms (cough, wheeze, shortness of breath, and awakening at night) and medication side-effects each on two dimensions (frequency and severity). 4-point Likert scale is used to assess frequency (not at all, 1 to 3 days, 4 to 7 days, and 8 to 14 days) and severity (not applicable, mild, moderate and severe). Scores range from 0 (worst possible symptoms) to 1 (no symptoms). The change between two time points, initial visit and after 24 weeks of treatment, is reported. The median value is reported with the standard deviation.
Outcome measure was assessed at the initial visit, at randomization following a wash-in period of 1 month, monthly for 24 weeks and a follow-up visit 1 month off study drug. Median scores, change from initial visit and end of treatment, were compared
