Real-world Efficacy and Safety of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) Modulator Therapy in Adult Patients With Cystic Fibrosis (CF)

August 30, 2022 updated by: Stefanie Vincken, Universitair Ziekenhuis Brussel

Real-world Efficacy and Safety of CFTR Modulator Therapy in Adult Patients With Cystic Fibrosis

In this trial real-world data on the safety (side effects and medication interactions) and efficacy (evolution of lung function testing, chronic bacterial airway infection, quality of life and endo- and exocrine pancreatic function) will be collected in adult people with cystic fibrosis (pwCF) eligible for elexacaftor-tezacaftor-ivacaftor (ETI) up until 2 years after the start of this therapy.

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.

Detailed Description

PwCF group A: CFTR-modulator-naive pwCF eligible for ETI (based on age and CFTR genotype)

PwCF group B: pwCF already on CFTR modulating therapy (i.e. ivacaftor-lumacaftor or ivacaftor-tezacaftor) and switching to ETI.

Patients in both groups will undergo these examinations:

  • Physical examination (including weight)
  • Anamnesis for current and recent medication use (including dosage of pancreatic enzymes) and for acute respiratory exacerbations
  • Lung function testing including spiometry, multiple breath washout testing and fractional exhaled nitric oxide
  • Blood sampling: liver function tests, creatine kinase, albumin, PT, red and white blood cell count, platelet count
  • Sputum/cough swab sampling
  • fecal elastase measurement
  • Cystic fibrosis questionnaire-revised (CFQ-R) questionnaire
  • Patient health questionnaire-9 (PHQ-9) questionnaire
  • General anxiety disorder-7 (GAD-7) questionnaire
  • Sino-nasal outcome test-22 (SNOT-22) questionnaire

These will be performed at baseline (prior to the start of ETI, on the same day of start of ETI), and every 3 months (+/- 7 days) thereafter. A blood sample will also be performed 14 (+/- 7 days) days after start of ETI (for safety). Fecal elastase measurement will only be performed at baseline if not available in the patient's medical record, and only 6 months after start of ETI.

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.

Enrollment (Anticipated)

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.
85

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • eligible for ETI (i.e. age above 18 years and CFTR genotype F508del/any) based on reimbursement criteria in Belgium

Exclusion Criteria:

  • inability to perform lung function testing

Other: ETI
pwCF which are CFTR-modulator naive and pwCF previously treated with a CFTR-modulator (i.e. tezacaftor-ivacaftor or lumacaftor-ivacaftor) will undergo standard-of-care examinations as well as examinations in the context of this trial (i.e. CFQ-R, PHQ-9, GAD-7 and SNOT-22 questionnaires, fecal elastase measurement)
Diagnostic test: CFQ-R questionnaire, SNOT-22 questionnaire, fecal elastase measurement

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.
