Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a Phase I, randomized, two-part, single-center pharmacokinetics (PK) study to assess the relative bioavailability of capsule and tablet formulations of GDC-0941 in the fasted state (Part 1) and to determine the effect of food and proton pump inhibition on the PK of the tablet formulation of GDC-0941 (Part 2). Approximately 18 subjects will be enrolled in Part 1 and up to 32 subjects will be enrolled in Part 2. Subjects who participate in Part 1 are not eligible to participate in Part 2.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GDC-0941 and rabeprazole in people with Healthy Volunteers, 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 8 inclusion and 23 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 9 Feb 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. 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?
Incidence, nature, and severity of adverse events (time frame: Through study completion or early study discontinuation). 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?
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 9 Feb 2017; AzTrials last refreshed its copy on 7 Nov 2026.
