What is being measured

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

  1. Visual Analog Scale (VAS) Pre-dose Pain Assessment

    VAS pain severity scale pre-dose, 6 hours post-operatively. The Visual Analog Scale (VAS) is a commonly used measurement of pain, discomfort, that goes from 0 meaning no pain to 100 meaning worst imaginable pain

    Measured: 6 hours

  2. Average Ocular Pain VAS Assessments

    VAS pain severity scale from the first post-operative assessment to pre-dose 12 hours post-operative assesment The Visual Analog Scale (VAS) is a commonly used measurement of pain, discomfort, that goes from 0 meaning no pain to 100 meaning worst imaginable pain

    Measured: 12 hours

Secondary outcomes (3)
  1. Incidence of and Amount of Rescue Oral Analgesics (Number of Participants Who Did Not Use Oral Rescue Medication)

    Summary of oral rescue medication use incidence (number of patients who DID NOT use oral rescue medication)

    Measured: 6,12, 24, 48 and 72 hours post-operatievly

  2. VAS Pain Assessments

    VAS pain assessment during the first 72 hours post-operatively. VAS pain severity scale from the first post-operative assessment to pre-dose 12 hours post-operative assesment The Visual Analog Scale (VAS) is a commonly used measurement of pain, discomfort, that goes from 0 meaning no pain to 100 meaning worst imaginable pain

    Measured: 72 hours

  3. Plasma Concentration of SAF312

    C Max

    Measured: day1, day 4

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SAF312 in people with Postoperative Ocular Pain After PRK Surgery, run by Novartis Pharmaceuticals 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 2 inclusion and 5 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 Oct 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 11 Apr 2019). 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?

Visual Analog Scale (VAS) Pre-dose Pain Assessment (time frame: 6 hours). The study lists 2 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 NCT02961062, which also lists 1 linked publication.

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 Oct 2021.
