Cryobiopsy Study to Assess Drug Distribution in Subjects With Suspected Interstitial Lung Disease

January 25, 2019 updated by: GlaxoSmithKline

Study to Assess Inhaled Drug Distribution in the Distal Lung and Interstitium Using Cryobiopsy Samples From Subjects With Suspected Interstitial Lung Disease Undergoing Cryobiopsy for Clinical Reasons

Interstitial lung disease (ILD) often affects distal lung, and the evaluation of drug distribution to the relevant lung compartments is essential for development of new treatment options. This single center study will utilize samples obtained by transbronchial cryobiopsy (TBCB) procedure to assess the distribution of inhaled drugs in the lungs of the subjects with fibrotic lung disease using mass spectrometry techniques. The study will have a single visit and will include approximately 20 adult subjects with suspected fibrotic ILD and requiring TBCB as part of their diagnostic assessment. This will provide TBCB samples from up to 20 subjects, up to 5 of whom may also provide endobronchial forceps biopsy samples. The study will have 3 phases including screening to check the eligibility, biopsy phase in which all subjects will receive nebulized ipratropium bromide 500 microgram (mcg) for 10 minutes immediately before undergoing bronchoscopy and follow up phase from 7 to 14 days after the procedure. Drug distribution in the lung will be assessed by analyzing biopsy samples collected using mass spectrometry and imaging techniques.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Male or female subjects above 18 years of age with suspected ILD referred for TBCB for clinical reasons, as part of their diagnostic work up, will be included in this study.

Description

Inclusion Criteria:

  • 18 and above years of age inclusive, at the time of signing the informed consent.
  • Subjects with suspected ILD listed for TBCB for clinical reasons following review by the ILD services at University College London Hospitals (UCLH) in whom diagnosis has remained unclear following radiological and clinical assessment.
  • A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied, may be included only if the investigator in consultation with the Medical Monitor agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
  • Male or Female.
  • Capable of giving signed informed consent which includes compliance with the requirements and restrictions.

Exclusion Criteria:

  • Subjects who have a known drug allergy or other contra-indication to ipratropium bromide.
  • Known hypersensitivity to atropine or ipratropium bromide or any other known drug allergies that, in the opinion of the investigator or GlaxoSmithKline (GSK) Medical Monitor, contraindicates their participation.
  • As a result of the medical history, physical examination or screening investigations, the physician responsible considers the subject unfit for the study.
  • The subject is unable or unwilling to perform study assessments and procedures correctly.
  • Subjects with a recognized co-existing respiratory disorder (other than ILD) that in the opinion of the investigator would confound the study outcomes.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Subjects with suspected fibrotic ILD
Eligible subjects will receive nebulized ipratropium bromide 500 mcg for 10 minutes. The subjects will be sedated for bronchoscopic procedure as per routine practice for subjects having bronchoscopy. Cryobiopsy samples for this study will be taken after samples required for diagnosis has been taken and it is safe to do so. One to three endobronchial forceps biopsy samples will be taken from up to 5 subjects to allow comparison of proximal and distal drug distribution.
Drug: Ipratropium Bromide
Single dose of 500 mcg Ipratropium nebulizer solution will be administered to all subjects via inhalation route using nebulizer for 10 minutes. Ipratropium bromide is a clear, colorless nebulizer solution available in white plastic ampoules.
Procedure: Flexible Bronchoscopy/Biopsy
After biopsy samples required for diagnosis have been collected, additional one to two TBCB samples will be taken for this study. 3-5 endobronchial biopsy samples will be taken from up to 5 subjects to compare drug distribution in proximal and distal lung.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame
Evaluation of the distribution of ipratropium bromide within the cryobiopsy samples
Time Frame: Up to Week 4
Images and data will be generated using mass spectrometric techniques and histology to show the distribution of ipratropium bromide within the lung cryobiopsy samples taken from subjects with suspected Interstitial Lung disease.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
