A Study of Pulmozyme® (Dornase Alpha) in 3- to 5-Year-Old Patients With Cystic Fibrosis

November 25, 2016 updated by: Genentech, Inc.

A Phase IV, Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial of Pulmozyme® in 3- to 5-Year-Old Patients With Cystic Fibrosis

This was a Phase IV, multicenter, randomized, double-blind, placebo-controlled trial designed to evaluate the effect of Pulmozyme on pulmonary function, health-related quality of life (HRQOL), and respiratory symptoms in 3- to 5-year-old children with cystic fibrosis (CF). Approximately 40 patients were planned to be enrolled in this study. However, only 3 patients were eligible for random allocation and received treatment: 1 patient in the Pulmozyme group and 2 patients in the placebo group. All 3 patients completed the study assessments but did not have usable pulmonary function test (PFT) data.

Study Overview

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

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

3 years to 5 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Signed Informed Consent Form
  • Aged 3-5 years
  • Diagnosis of cystic fibrosis

Exclusion Criteria:

  • Children taking scheduled inhaled Pulmozyme or hypertonic saline within 56 days prior to Visit 1 or any Pulmozyme in the 28 days before Visit 1
  • Involvement in a clinical intervention trial within the 4 weeks prior to Visit 1
  • Use of an investigational drug or device within 28 days prior to Visit 1
  • Any other condition that might increase the risk of participation to the patient in the judgement of the investigator

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 Reactance at 8 Hz (Xrs8) From Visit 2 to Visit 3 (Change From Baseline at Visit 2 to Visit 3, After Study Drug Treatment).
Time Frame: from Visit 2 to Visit 3 (16 +/- 2 days)
The fundamental principle of forced oscillometry is that lung function can be assessed by measuring changes in pressure and flow in response to external pressure applied at the airway opening. Reactance is complex measure that incorporates the changes in pressure and volume and the rate of these changes in response to pressure oscillations at a specific frequency. (8Hz was used for the primary endpoint). Reactance is thought to reflect the elastic properties of the lung.
from Visit 2 to Visit 3 (16 +/- 2 days)

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 Reactance at 4, 6, and 10 Hz (Xrs4, Xrs6, and Xrs10)
Time Frame: from Visit 2 to Visit 3 (16 +/- 2 days)
The fundamental principle of forced oscillometry is that lung function can be assessed by measuring changes in pressure and flow in response to external pressure applied at the airway opening. Reactance is complex measure that incorporates the changes in pressure and volume and the rate of these changes in response to pressure oscillations at a specific frequency. (8Hz was used for the primary endpoint). Reactance is thought to reflect the elastic properties of the lung.
from Visit 2 to Visit 3 (16 +/- 2 days)
Change in Resistance at 4, 6, 8, and 10 Hz (Rrs4, Rrs6, Rrs8, and Rrs10)
Time Frame: from Visit 2 to Visit 3 (16 +/- 2 days)
The fundamental principle of forced oscillometry is that lung function can be assessed by measuring changes in pressure and flow in response to external pressure applied at the airway opening. Resistance is complex measure that incorporates the lack of changes in pressure and volume and the rate of these changes in response to pressure oscillations at a specific frequency. (10Hz was used for the secondary endpoint).
from Visit 2 to Visit 3 (16 +/- 2 days)
Change in Respiratory Symptom Domain Score From the Cystic Fibrosis Questionnaire Revised (CFQ-R) for Parents of Preschoolers and for Preschoolers
Time Frame: from Visit 2 to Visit 3 (16 +/- 2 days)

The CFQ-R for Preschoolers and the CFQ-R for Parents of Preschoolers was designed specifically to measure the impact of CF for patients with a diagnosis of CF. Each question is answered using a 4-point Likert scale.

In order to calculate the domain/symptom scale scores, the following algorithm is followed

  • Re-number items which have been reverse coded
  • Calculate the mean of the items to be included. If more than half of the items are missing, then the score is considered missing
  • Re-scale to result in a scaled score which ranges from 0 to 100, with higher scores indicating better health
from Visit 2 to Visit 3 (16 +/- 2 days)
