Safety, Tolerability and Pharmacokinetics of Multiple Rising Inhalative Doses of Butylated Hydroxytoluene Via Respimat Soft MistTM Inhaler B (Sub-study 1) and Safety, Tolerability and Pharmacokinetics of Multiple Rising Inhalative Doses of BI 54903 XX Via Respimat Soft MistTM Inhaler B as Randomised, Double-blind, Placebo-controlled Phase I Trial in Healthy Male Volunteers (Main Study) and Comparison of Systemic Exposure Following a Single Dose of BI 54903 XX Via Respimat Soft MistTM Inhaler B and of a Single Dose of Ciclesonide Via MDI (Randomised, Open-label, Two-way Crossover Sub-study 2)

The objective of the study was to investigate safety, tolerability and pharmacokinetics of butylated hydroxytoluene (BHT) (sub-study 1) administered via Respimat® Soft MistTM Inhaler B (SMI B); to assess safety, tolerability and pharmacokinetics of multiple rising doses of BI 54903 XX administered via Respimat® SMI B (main study), and to compare systemic exposure of single dose BI 54903 XX administered via Respimat® SMI B (sub-study 2) with single dose Alvesco® (ciclesonide) administered via HFA-134a propellant metered dose inhaler (MDI).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
