What is being measured

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

  1. Time-weighted Sum of the Pain Intensity Difference (SPID) Between VX-150 Versus Placebo as Recorded on a Numeric Pain Rating Scale (NPRS) 0 to 24 Hours After the First Dose

    SPID was calculated as the sum of the product of time (in hours) elapsed since previous measurements and pain intensity difference. Pain intensity difference was calculated by subtracting the pain intensity score at given post-dose time points from the baseline pain intensity scores (using pain rating score range: 0 =no pain to 10 =worst possible pain). SPID24 was calculated from 0 to 24 hours and the score range was -240 (worst score) to 240 (best score).

    Measured: 0 to 24 hours after the first dose

Secondary outcomes (11)
  1. Time-weighted Sum of the Pain Intensity Difference Between VX-150 Versus Placebo as Recorded on a NPRS 2 to 24 Hours After the First Dose

    SPID was calculated as the sum of the product of time (in hours) elapsed since previous measurements and pain intensity difference. Pain intensity difference was calculated by subtracting the pain intensity score at given post-dose time points from the baseline pain intensity scores (using pain rating score range: 0 =no pain to 10 =worst possible pain). SPID22 was calculated from 2 to 24 hours and the score range was -220 (worst score) to 220 (best score).

    Measured: 2 to 24 hours after the first dose

  2. Time-weighted Sum of the Pain Intensity Difference Between VX-150 Versus Placebo as Recorded on a NPRS 0 to 48 Hours After the First Dose

    SPID was calculated as the sum of the product of time (in hours) elapsed since previous measurements and pain intensity difference. Pain intensity difference was calculated by subtracting the pain intensity score at given post-dose time points from the baseline pain intensity scores (using pain rating score range: 0 =no pain to 10 =worst possible pain). SPID48 was calculated from 0 to 48 hours and the score range was -480 (worst score) to 480 (best score).

    Measured: 0 to 48 hours after the first dose

  3. Time to Onset of Perceptible Pain Relief After the First Dose of VX-150 Versus Placebo

    Time to onset of perceptible pain relief (any pain relief at all after the first dose) reported based on the first stopwatch assessment.

    Measured: up to 6 hours after the first dose

  4. Time to Onset of Meaningful Pain Relief After the First Dose of VX-150 Versus Placebo

    Time to onset of meaningful pain relief (relief that is meaningful to participants after the first dose) reported based on the second stopwatch assessment.

    Measured: up to 6 hours after the first dose

  5. Time to First Rescue Medication After the First Dose of VX-150 Versus Placebo

    Time to first rescue medication was the time elapsed from the first dose of VX-150 or placebo until the participants received the first dose of rescue medication.

    Measured: up to 48 hours after the first dose

  6. Percentage of Participants Using Rescue Medication After the First Dose VX-150 Versus Placebo

    Measured: 0 to 24 hours after the first dose and 24 to 48 hours after the first dose

  7. Total Rescue Medication Used After the First Dose of VX-150 Versus Placebo

    Total use of rescue medication was calculated as the sum of number of capsules multiplied by capsule strength at each dosing occasion of rescue medication. Rescue medication was ibuprofen (400 mg [oral] every 4 hours (q4h) as needed).

    Measured: 0 to 24 hours after the first dose and 24 to 48 hours after the first dose

  8. Maximum Observed Concentration (Cmax) of VRT- 1207355 (Active Moiety) and VRT- 1268114 (Metabolite M5)

    Measured: Day 1 and Day 2

  9. Time to Reach Maximum Observed Plasma Concentration (Tmax) of VRT- 1207355 and VRT- 1268114

    Measured: Day 1 and Day 2

  10. Area Under the Concentration Versus Time Curve From 0 to 12 Hours (AUC0-12h) of VRT- 1207355 and VRT- 1268114

    Measured: Day 1 and Day 2

  11. Safety and Tolerability as Assessed by Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Measured: From Day 1 up to Day 10

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing VX-150 and HB/APAP in people with Acute Pain, run by Vertex Pharmaceuticals Incorporated at 4 sites in United States.

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 7 inclusion and 13 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 3 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. 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 phase mean?

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 3 Feb 2021). 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?

Time-weighted Sum of the Pain Intensity Difference (SPID) Between VX-150 Versus Placebo as Recorded on a Numeric Pain Rating Scale (NPRS) 0 to 24 Hours After the First Dose (time frame: 0 to 24 hours after the first dose). 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 3 Feb 2021.
