Safety, Tolerability and Pharmacodynamics After Oral Administration of BIIF 1149 BS in Healthy Male Volunteers

August 5, 2014 updated by: Boehringer Ingelheim

A Single Increasing Dose Safety, Tolerability and Pharmacodynamics (Citric Acid Challenge) Study After Oral Administration of BIIF 1149 BS (Single Doses as Tablets: 40, 65, 100 mg) in Healthy Male Volunteers (Randomised, Double-blind Within Each Dose Group, Placebo-controlled, Parallel Groups)

The objective of the study is to obtain information about the safety and tolerability of BIIF 1149 BS45 (single dose: 40, 65, 100 mg), to determine the pharmacologically active dose (range) by performing a citric acid challenge test and to obtain preliminary pharmacokinetic data.

Study Overview

Status

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

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.

Study Type

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.

Ages Eligible for Study

21 years to 50 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

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.
Outcome Measure
Time Frame
Number of patients with adverse events
Time Frame: up to 8 days after last drug administration
up to 8 days after last drug administration
Number of patients with clinically relevant changes in vital functions (blood pressure, pulse rate)

up to 8 days after last drug administration

Secondary Outcome Measures

Secondary Outcome Measures

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.
