    Measured: Day 1 and Day 15

  10. Part D: Area Under the Concentration Versus Time Curve From the Time of Dosing to the Last Measurable Concentration (AUC[0-last]) of VX-121, TEZ and Its Metabolites (M1-TEZ and M2-TEZ) and IVA and Its Metabolites (M1-IVA and M6-IVA)

    Measured: Day 1 and Day 15

  11. Part D: Pre-dose Plasma Concentration (Ctrough) of VX-121, TEZ and Its Metabolites (M1-TEZ and M2-TEZ) and IVA and Its Metabolites (M1-IVA and M6-IVA)

    Measured: Pre-dose at Day 8, Day 15, and Day 29

  12. Part D: Absolute Change in Sweat Chloride (SwCl) Concentrations

    Sweat samples were collected using an approved collection device.

    Measured: From Baseline Through Day 29

  13. Part D: Absolute Change in Percent Predicted Forced Expiratory Volume in 1 Second (ppFEV1)

    FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration.

    Measured: From Baseline Through Day 29

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing VX-121 (Suspension), TEZ/IVA and IVA in people with Cystic Fibrosis, run by Vertex Pharmaceuticals Incorporated at 7 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Netherlands, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Jul 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and Tolerability as Assessed by Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) (time frame: From Day 1 Through Safety Follow-up (up to Day 15 for Part A [except Cohorts A3 and A9], up to Day 26 for Cohort A3, up to Day 34 for Cohort A9, up to Day 20 for Part B, up to Day 24 for Part C and up to Week 9 for Part D)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jul 2022.
