Study groups in NCT03601637
Study groupRoleWhat they receive
Part A: LUM/IVAExperimentalParticipants weighing 7 to less than (<)10 kilograms (kg) at screening received LUM 75 milligrams (mg)/IVA 94 mg fixed-dose combination (FDC) every 12 hours (q12h) and those weighing 10 to <14 kg at screening received LUM 100 mg/IVA 125 mg q12h for 15 days. Participants weighing greater than or equal to (>=)14 kg at screening received LUM 150 mg/IVA 188 mg FDC q12h for 15 days.
Receives: Drug: LUM; Drug: IVA
Part B: LUM/IVAExperimentalParticipants weighing 7 to <9 kg at screening received LUM 75 mg/IVA 94 mg FDC q12h and those weighing 9 to <14 kg received LUM 100 mg/IVA 125 mg q12h for 24 weeks. Participants weighing >=14 kg at screening received LUM 150 mg/IVA 188 mg FDC q12h for 24 weeks. Doses were adjusted upwards for changes in weight.
Receives: Drug: LUM; Drug: IVA

What is being measured

The primary outcome is the main question the study is designed to answer.

    Measured: Day 1 and Day 15

  2. Part A: Observed Pre-dose Plasma Concentration (Ctrough) of LUM and IVA

    Measured: Pre-dose at Day 8 and Day 15

  3. Part B : Safety and Tolerability as Assessed by Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

    Measured: From Day 1 up to Week 26

Secondary outcomes (4)
  1. Part A: Safety and Tolerability as Assessed by Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

  2. Part A: Observed Pre-dose Plasma Concentration (Ctrough) of LUM and IVA and Their Respective Metabolites (M28-LUM, M1-IVA and M6-IVA)

    Measured: Pre-dose at Day 8 and Day 15

  3. Part B: Absolute Change in Sweat Chloride

    Measured: From Baseline at Week 24

  4. Part B: Observed Pre-dose Plasma Concentration (Ctrough) of LUM and IVA and Their Respective Metabolites (M28-LUM, M1-IVA and M6-IVA)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing LUM and IVA in people with Cystic Fibrosis, run by Vertex Pharmaceuticals Incorporated at 27 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 2 inclusion and 3 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 6 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 27 sites in United States, Canada. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 6 Jan 2023). 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?

Part A: Observed Plasma Concentrations From 3-4 Hours (C3-4hr) of LUM and IVA (time frame: Day 1 and Day 15). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03601637, which also lists 3 linked publications.

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 6 Jan 2023.
