About this study

Official title: An Exploratory Fixed Dose Randomized Double Blind Parallel-group Placebo-controlled Study of the Safety and of the Therapeutic Effects of Ro 4917523 in Patients With Treatment- Resistant Depression

This study will evaluate the safety, tolerability and efficacy of RO4917523, in comparison to placebo, in patients with treatment-resistant depression. Following a washout period from existing anti-depressant medication, cohorts of patients will be randomized to receive daily oral RO4917523 at up to five different doses (according to the safety and tolerability observed at the lower doses during the study), or placebo. The anticipated time on study treatment is 10 days (in an inpatient unit), and the target sample size is <100 individuals.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RO4917523 in people with Depression, run by Hoffmann-La Roche at 9 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 5 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 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 9 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?

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?

Safety and tolerability: Adverse events, ECGs, laboratory parameters,vital signs (time frame: Throughout study). 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.
