About this study
Official title: Human Abuse Liability Study in Recreational Drug Users to Investigate the Abuse Liability Potential of RO4917838
This randomized, placebo- and active-controlled, crossover study will evaluate the abuse liability potential of RO4917838 in recreational drug users. In a pre-study (Part 1), subjects will receive a single dose of either diazepam or placebo in an inpatient crossover design, with a wash-out period of at least 10 days between treatments. Subjects who are clearly able to distinguish the positive control from placebo will be enrolled in the main study (Part 2) and will be randomized to single oral doses of RO4917838 (3 dose levels), diazepam and placebo in a double-blind, double-dummy inpatient crossover design. Washout-periods between the 5 treatment periods in Part 2 will be at least 10 days.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This randomized, placebo- and active-controlled, crossover study will evaluate the abuse liability potential of RO4917838 in recreational drug users. In a pre-study (Part 1), subjects will receive a single dose of either diazepam or placebo in an inpatient crossover design, with a wash-out period of at least 10 days between treatments. Subjects who are clearly able to distinguish the positive control from placebo will be enrolled in the main study (Part 2) and will be randomized to single oral doses of RO4917838 (3 dose levels), diazepam and placebo in a double-blind, double-dummy inpatient crossover design. Washout-periods between the 5 treatment periods in Part 2 will be at least 10 days.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing RO4917838 and diazepam in people with Healthy Volunteer, run by Hoffmann-La Roche at 1 site 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 4 inclusion and 10 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 2 Nov 2016. 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 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 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.
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?
Pharmacodynamics: Abuse potential measured by Visual analogue scales (VAS) (time frame: approximately 11 months). 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 2 Nov 2016.
