A Trial of Pulmozyme Withdrawal on Exercise Tolerance in Cystic Fibrosis Subjects With Severe Lung Disease (TOPIC)

May 12, 2017 updated by: Genentech, Inc.

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial of Pulmozyme Withdrawal on Exercise Tolerance in Cystic Fibrosis Subjects With Severe Lung Disease

This was a multicenter, randomized, double-blind, placebo-controlled study of patients with severe, though stable, cystic fibrosis (CF) whose routine treatment included Pulmozyme. Patients were randomized to either continue Pulmozyme or have therapy withdrawn for 2 weeks (placebo group). Patients must have had stable CF symptoms without any change in therapy for 2 weeks prior to enrollment in order to participate.

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

14 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Measure Description
Time Frame
Change in Distance Walked in the 6-minute Walk Test
Time Frame: From baseline to Day 14
Change in distance walked was defined as (distance walked in 6 minutes at baseline [Day 0]) - (distance walked in 6 minutes at Day 14) in meters.
From baseline to Day 14

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.
Outcome Measure
Measure Description
Time Frame
Change in Pulmonary Function as Measured by FEV1 and FVC
Time Frame: From baseline to Day 14
FEV1 (forced expiratory volume in 1 second) and FVC (forced vital capacity) were recorded at Day 0 (baseline) and Day 14. Change in FEV1 and FVC from baseline to Day 14 was reported as a percentage of values predicted for age, height, and race.
From baseline to Day 14

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2007

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.
November 1, 2008

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
