About this study
Official title: A Phase I, Single Center, Randomized, Open-Label, Study Investigating the Effect of Food, Rabeprazole, Methotrexate and Formulation on the Pharmacokinetics of GDC-0853 and the Effect of GDC-0853 on the Pharmacokinetics of Methotrexate in Healthy Subjects
This study is a Phase I, single center, randomized (Parts 1 and 2 only), open-label, 3 part study. Parts 1 and 2 are 2-way crossover, with 1-fixed sequence, 3-period designs to investigate the effect of formulation, food and rabeprazole on the PK of GDC-0853 in healthy male and female (of non-childbearing potential) participants. Part 3 is a fixed-sequence study with 3 treatments to characterize the steady-state PK of the GDC-0853 tablet; the effect of simultaneous administration of a single dose of methotrexate on the steady-state kinetics of GDC-0853; and the effect of dosing GDC-0853 to steady-state on the single dose PK of methotrexate in healthy male participants.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study is a Phase I, single center, randomized (Parts 1 and 2 only), open-label, 3 part study. Parts 1 and 2 are 2-way crossover, with 1-fixed sequence, 3-period designs to investigate the effect of formulation, food and rabeprazole on the PK of GDC-0853 in healthy male and female (of non-childbearing potential) participants. Part 3 is a fixed-sequence study with 3 treatments to characterize the steady-state PK of the GDC-0853 tablet; the effect of simultaneous administration of a single dose of methotrexate on the steady-state kinetics of GDC-0853; and the effect of dosing GDC-0853 to steady-state on the single dose PK of methotrexate in healthy male participants.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Folic Acid, GDC-0853 and Methotrexate in people with Healthy Volunteer, run by Genentech, Inc. at 1 site in United Kingdom.
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 3 inclusion and 7 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 Mar 2020. 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 Kingdom. 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?
Part 1: Relative Bioavailability of GDC-0853 tablet Compared to GDC-0853 Capsule (time frame: Part 1 (Periods 1 to 2 [Period length=5 days]): Predose (</=1 hour before dosing), 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 hours postdose on Day 1; 24, 36 hours postdose on Day 2; 48 hours postdose on Day 3; 72 hours postdose on Day 4). The study lists 26 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 2 Mar 2020; AzTrials last refreshed its copy on 7 Nov 2026.
