A Study to Confirm the Long-term Safety and Effectiveness of Kalydeco in Patients With Cystic Fibrosis Who Have an R117H-CFTR Mutation, Including Pediatric Patients

February 4, 2020 updated by: Vertex Pharmaceuticals Incorporated

A Study in US Cystic Fibrosis Patients With the R117H-CFTR Mutation to Confirm the Long-term Safety and Effectiveness of Kalydeco, Including Patients <18 Years of Age, Combining Data Captured in the Cystic Fibrosis Foundation Registry From an Interventional Cohort and a Non-Interventional Cohort

The purpose of this study is to confirm the long-term safety and effectiveness of Kalydeco® (ivacaftor) in US CF patients with the R117H-CFTR mutation <18 years of age and to describe the long-term safety and effectiveness of Kalydeco in CF patients with the R117H-CFTR mutation overall and in patients ≥18 years. The long-term safety and effectiveness of Kalydeco will be examined in totality through the evaluation of the primary outcome measures.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

Patient follow-up (i.e., collection of outcomes data after treatment initiation) in the Non-Interventional Cohort will be at least 36 months. The study also includes retrieval of retrospective data entered into the registry for 36 months before the initiation of Kalydeco treatment, from patients matched for Non-Interventional Cohorts. This will permit a within-group comparison of outcomes before and after Kalydeco treatment for effectiveness and safety. The interventional cohort will not be utilized.

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.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

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.
Cohort 1 - Interventional
The Interventional cohort will not be utilized.
Cohort 2 - Non Interventional
A Non-Interventional Cohort comprising pediatric (<18 years of age) and adult R117H-CFTR patients treated with commercially-available Kalydeco.
Cohort 3 - Historical
A Historical Cohort comprising data from an earlier time period for pediatric (<18 years of age) and adult patients with the R117H-CFTR mutation who have never been exposed to Kalydeco and matched on age, gender, and lung function to patients in the Non-Interventional Cohort.

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
Lung function measurements (percent predicted forced expiratory volume in 1 second [FEV1] and forced vital capacity [FVC])
Time Frame: 36 Months
Spirometry will be performed according to the standard procedure at each site, and FEV1 values as recorded in the registry will be evaluated. All descriptive and summary data collected for FEV1 will be repeated for FVC
36 Months
Pulmonary exacerbations, use of IV antibiotics
Time Frame: 36 Months
Pulmonary exacerbation data will be collected as recorded in the registry.
36 Months
Nutritional parameters (body mass index [BMI], BMI-for-age z-score, weight, and weight-for-age z-score)
Time Frame: 36 Months
Height and weight measurements as recorded in the registry will be evaluated. BMI, BMI-for-age z-score, and weight-for-age z-score will be derived
36 Months
Death or transplantation
Time Frame: 36 months
Death will be collected from the registry database.
36 months
Hospitalizations
Time Frame: 36 Months
Hospitalizations will be collected from the registry database.
36 Months
Selected Complications (Symptomatic sinus disease, Pulmonary complications, CF-related diabetes (CFRD) and distal intestinal obstruction syndrome (DIOS), Hepatobiliary complications, Pancreatitis)
Time Frame: 36 Months
Information for the above shown CF-related complications as recorded in the registry will be evaluated
36 Months
Select pulmonary microorganisms (e.g., P. aeruginosa, S. aureus)
Time Frame: 36 Months
Data on microorganisms as recorded in the registry will be evaluated
36 Months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

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.

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.
