About this study

Official title: A Phase 1, Randomized, Placebo-Controlled, Double-Blind, Single and Multiple Ascending Dose Study to Assess the Safety, Tolerability, and Pharmacokinetics of Intravenous and Subcutaneous RO7105705 Administered in Healthy Volunteers and Patients With Mild-to-Moderate Alzheimer's Disease

This is a Phase I, randomized, placebo-controlled, double-blind study to evaluate the safety, tolerability, pharmacokinetics, and preliminary activity of RO7105705 in two participant populations: healthy participants and participants with mild-to-moderate Alzheimer's disease. This study is a single dose, dose-escalation, and multiple dose study comprising approximately six single dose cohorts in healthy participants administered RO7105705, either intravenously (IV) or subcutaneously (SC), and comprising one or more multiple dose cohorts in healthy participants administered RO7105705 IV every week (QW), a total of 4 doses, and one or more multiple dose cohorts in participants with Alzheimer's disease administered RO7105705 IV QW, a total of 4 doses.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing RO7105705 in people with Alzheimer's Disease, run by Genentech, Inc. 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 22 inclusion and 24 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 21 Jul 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 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?

Number of Participants with Adverse Events (time frame: Screening up to Day 134). The study lists 3 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 NCT02820896, which also lists 2 linked publications.

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 21 Jul 2017.
