Who cannot join

  • Past or present disease, which as judged by the investigator, may affect the outcome of the study. These diseases include, but are not limited to, cardiovascular disease, malignancy, hepatic disease, renal disease, hematological disease, neurological disease, psychiatric disease, endocrine disease, infectious disease, inflammatory disease or pulmonary disease (including but not confined to asthma, tuberculosis, bronchiectasis or cystic fibrosis)

  • Any clinically relevant abnormal findings in physical examination, clinical chemistry, hematology, urinalysis, vital signs, lung function, or ECG at Visit 1, which, in the opinion of the investigator, may either put the subject at risk because of participation in the study, or may influence the results of the study, or the subject's ability to participate in the study

About this study

Official title: Understanding the Lung Pharmacokinetics (PK) in Humans by Direct Sampling of Epithelial Lining Fluid (ELF) After Inhalation and Oral Administration of Model Drugs

The aim of the present study is to increase the general understanding of lung PK of selected compounds by sampling epithelial lining fluid ELF and lung tissue.

Read the detailed description

This study will investigate drug levels of selected compounds at multiple sites in the lung and explore different innovative sampling methods to obtain information on lung PK. The aim of the study is not to generate safety or efficacy data of the selected licensed drugs. The choice of drugs is based on general considerations regarding therapy of airway diseases and the physical-chemical properties of the compounds. It is not driven by the compounds per se.

Being tested
Inhalation, Systemic, Bronchoscopy

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • InhalationDrug

    Salbutamol(200µg), Salmeterol (50µg) and Fluticasone propionate (500µg) by inhalation

  • SystemicDrug

    Salbutamol 8mg M/R Tablet, Propranolol 40 mg administered orally

  • BronchoscopyOther

    Bronchoadsorption sample, bronchial brushing, mucosal biopsy, and BAL samples during bronchoscopy

Study groups in NCT03524066
Study groupRoleWhat they receive
Inhaled + BronchoscopyExperimentalOne-time Inhalation of Salbutamol 200 µg, Salmeterol 50µg and Fluticasone 500µg. During two bronchoscopic procedures two pre-specified lung tissue sites (middle lobe and lingula) will be sampled. Bronchoadsorption sample, bronchial brushing, mucosal biopsy, and bronchoalveolar lavage (BAL) samples will be taken from each site.
Receives: Drug: Inhalation; Other: Bronchoscopy
Systemic + BronchoscopyExperimentalOne-time Salbutamol (8 mg) and Propranolol (40mg) administered orally. During two bronchoscopic procedures two pre-specified lung tissue sites (middle lobe and lingula) will be sampled. Bronchoadsorption sample, bronchial brushing, mucosal biopsy, and BAL samples will be taken from each site.

    Measured: change from baseline to 1 hour and 24,5 hours post dose

  2. Maximum concentration of Salmeterol in the lung

    Maximum concentration of Salmeterol in samples from bronchoscopy (bronchoadsorption, bronchial brushing, mucosal biopsy, Bronchoalveolar lavage (BAL))

    Measured: change from baseline to 1 hour and 24,5 hours post dose

  3. Maximum concentration of Fluticasone in the lung

    Maximum concentration of Fluticasone in samples from bronchoscopy (bronchoadsorption, bronchial brushing, mucosal biopsy, Bronchoalveolar lavage (BAL))

    Measured: change from baseline to 1 hour and 24,5 hours post dose

  4. Maximum concentration of Propranolol in the lung

    Maximum concentration of Propranolol in samples from bronchoscopy (bronchoadsorption, bronchial brushing, mucosal biopsy, Bronchoalveolar lavage (BAL))

Questions about this trial

What is this clinical trial studying?

A study testing Inhalation, Systemic and Bronchoscopy in people with Healthy, run by Fraunhofer-Institute of Toxicology and Experimental Medicine at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum concentration of Salbutamol in the lung (time frame: change from baseline to 1 hour and 24,5 hours post dose). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2019; AzTrials last refreshed its copy on 3 Nov 2026.
