Study groupRoleWhat they receive
methylphenidate hydrochlorideExperimentalThe study will include two sessions which will be conducted at the same time of the day, one week apart from each other. Each session will last approximately 6 hours. In each session subjects will be exposed to baseline experimental pain models and auditory tests. Then they will receive either one MP SR 20 mg tablet or an identical looking placebo.

What is being measured

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

  1. Experimental pain intensity measured on a visual analogue scale (0-100)

    Measured: 4 hours

Secondary outcomes (2)
  1. effect of Ritalin on auditory sensitivity, measured by the response to different auditory stimulations

    Measured: 4 hours

  2. pain intensity (NPS 0-100) in response to thermal stimuli and the measures of the auditory tests.

    Measured: 4 hours

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing methylphenidate hydrochloride in people with Pharmacological Action (PA), run by Rambam Health Care Campus at 1 site in Israel.

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 6 inclusion and 4 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 12 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Experimental pain intensity measured on a visual analogue scale (0-100) (time frame: 4 hours). 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 12 Sep 2017.
