Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1. Pulmozyme was given once daily via nebuliser for 2 weeks @ 2.5mg/dose

2. During days 1-14 the subjects were given one order of therapy (eg placebo saline, followed by physio then Pulmozyme) and then days 15-28 they were given the reverse order, in this case (Pulmozyme, followed by physio then placebo)

3. the federal government allows doctors to trial Pulmozyme for one month (28-30 days) as part of the PBS S100 listing. We designed the trial to keep within this requirement.

4. Physiotherapy was optimised by an experienced physiotherapist before the trial. The patients performed the same physio techniques every day during the trial – by themselves, individually, at home, as per standard CF Physiotherapy used clinically–

Generally it takes about 30-40 minutes, but the patient does the same thing every day before during and after the trial, with the endpoint that they have no more sputum that requires clearance techniques.


This trial will directly compare Pulmozyme given before versus after physiotherapy. To maintain blinding, a matched saline nebulized therapy will be given at the other time point.
The study comprises three components – baseline, first period (two weeks) followed immediately (no wash out) where two weeks of the reverse order. This duration was chosen to maintain within the Pulmozyme one month trial.

Treatment: Drugs
Comparator / control treatment
Intervention = Pulmozyme given after physiotherapy
Pulmozyme given after physiotherapy is the test, compared with the control of Pulmozyme given before physiotherapy.
Given the requirement for a placebo, the two arms are
1) pre/post:- Pulmozyme/physiotherapy/saline followed by saline/physiotherapy/Pulmozyme., which is tested in half the subjects.
2) Post/pre:- The other half of the subjects undertake the trial in the reverse order.

Group 1 = Post / Pre = . During days 1-14 the subjects were given each day the following treatments : (saline, followed by physio then Pulmozyme) and then days 15-28 they were given (Pulmozyme, followed by physio then placebo).

Group 2 = Pre / Post =. During days 1-14 the subjects were given each day the following treatments : (Pulmozyme, followed by physio then placebo) and then days 15-28 they were given (saline, followed by physio then Pulmozyme).

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation to intervention was concealed using sealed envelopes as the allocation group performed in blocks of four, with allocation performed by a pharmacist who was not involved in trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequence generation created by randomized table from computer.
