Study summary

The purpose of this study is to validate the user interface of TOBI Podhaler by establishing that the product can support safe and effective use for the intended users

Read the detailed description

The objective is to conduct a human factors validation study to demonstrate that the user interface of TOBI® Podhaler™ can support safe and effective use for the intended users. The human factors validation study will be conducted in patients with cystic fibrosis aged 6 years and older under simulated yet representative of realistic use conditions where patients with no prior training or use of TOBI® Podhaler™ will be asked to inhale the contents of placebo capsules through the Podhaler device. Due to the use of placebo capsules, the study is considered an interventional clinical study and will be conducted accordingly. The study is an open label, un-blinded, non-randomized study which consists of one visit.

  • Male and female subjects aged 6 years and older
  • Confirmed diagnosis of CF by one or more of the following tests for CF as documented in the patient's medical history : (1) quantitative pilocarpine iontophoresis sweat chloride test of > 60 mmol/L or 60 mEq/L, (2) genotype with identifiable CF-causing mutations on both chromosomes, (3) an abnormal nasal transepithelial potential difference characteristic of CF
  • FEV1 value must be at least 25% of normal predicted values for age, sex, and height as documented in the patient's medical history (historical values within 3 months can be used for this criterion).
