Vanzacaftor

Clinical trials are studying Vanzacaftor in people with cystic fibrosis. These studies look at long-term safety, tolerability, and treatment effects in children and adults, including patients 1 year of age and older. The trials are in Phase 3 and focus on how well the treatment is used over time.

Trial overview

The available studies of Vanzacaftor are all in people with cystic fibrosis, and all are Phase 3 interventional trials.[1][2][3]

These trials are authorised and are designed to look mainly at long-term safety and tolerability, with one study also looking at pharmacokinetics, which means how the treatment is handled by the body.[1][3]

Who is being studied

One trial includes subjects 1 year of age and older, showing that the research covers both children and adults with cystic fibrosis.[1]

Another trial is focused on subjects 1 through 11 years of age, which means it is aimed at younger children with cystic fibrosis.[3]

A third Phase 3 study includes subjects with cystic fibrosis in a broader group and has the largest planned enrollment in the source data.[2]

What the trials measure

The main safety outcomes include adverse events, clinical laboratory values, ECGs, vital signs, and pulse oximetry.[1][2][3]

Adverse events are any unwanted medical problems seen during a study, whether or not they are caused by the treatment.[1]

ECGs are heart tests, vital signs are basic body measurements, and pulse oximetry checks blood oxygen levels.[1][2][3]

One study also measures PK parameters, a short name for pharmacokinetic data, which describes how the body absorbs and processes the treatment and its related metabolites.[3]

Trial phases and status

All three trials are in Phase 3, which is a later stage of clinical research used to study treatment performance in larger groups of patients.[1][2][3]

Each study is listed as Authorised, so they are approved to move forward according to the source data.[1][2][3]

The planned enrollment numbers are 134, 844, and 122 participants, showing that the studies vary in size.[1][2][3]

Trial designs and treatment groups

All listed studies are interventional, meaning researchers give study treatments and then observe the results.[1][2][3]

The source data lists several treatment forms, including film-coated tablets and granules, and also includes product names such as Alyftrek, Kalydeco, and Kaftrio in the intervention lists.[1][2][3]

In the study titles and summaries, the treatment is described as Vanzacaftor/tezacaftor/deutivacaftor or VX-121/TEZ/D-IVA, which appears as the main triple-combination study treatment in the source data.[1][2][3]

Key patient points

These trials are focused on cystic fibrosis, not on other diseases.[1][2][3]

The main question is whether long-term treatment can be used safely and well over time in the studied age groups.[1][2][3]

One study also adds body-processing data, which can help researchers understand how the treatment behaves in younger children and other participants.[3]

Glossary

  • Cystic fibrosis: A long-term genetic disease studied in all of the listed trials. The trials focus on people living with this condition.
  • Phase 3: A later stage of clinical research. These studies are usually larger and help show how safe and useful a treatment is in a patient group.
  • Interventional study: A study where people receive a treatment being tested, so researchers can measure its effects.
  • Safety: How well a treatment can be used without causing major problems. In these trials, safety is checked with tests and patient monitoring.
  • Tolerability: How well people can handle a treatment. It looks at whether the treatment is acceptable and manageable over time.
  • Adverse events: Medical problems or unwanted health changes that happen during a study, whether or not they are caused by the treatment.
  • Clinical laboratory values: Results from blood or other lab tests that help researchers watch health and safety during the study.
  • ECG: Short for electrocardiogram. It is a test that records the heart’s electrical activity.
  • Vital signs: Basic body measurements such as heart rate, blood pressure, and temperature.
  • Pulse oximetry: A simple test that measures oxygen level in the blood.
  • Pharmacokinetics: A way to study how the body absorbs, moves, and removes a treatment.
  • Enrollment: The number of people planned or included in a study.
