About this study

Official title: A Phase I, Randomized, Open-Label, Single Center Study to Investigate the Effect of Formulation and Food on the Pharmacokinetics of GDC-0810 in Female Healthy Subjects on Non-Childbearing Potential

This is a phase 1, randomized, open-label, single center, crossover study to investigate the effect of formulation and food on the pharmacokinetics of GDC-0810 in female healthy participants of non-childbearing potential. This study is divided into three parts. Participants in each part will be randomized to one of three treatment sequences. Part 1 study in 4 periods will investigate the effect of formulation on the pharmacokinetics (PK) of GDC-0810 administered with low-fat food. Each participant in this part will receive a single dose of GDC-0810 dose level A following consumption of a low fat meal (30 minutes after the start of the meal) in each treatment period. Part 2 is an optional Phase I study in 3 periods to investigate the effect of formulation on the PK of GDC-0810 administered with low-fat food in healthy female participants of non-childbearing potential. Part 3 study in three periods will compare the PK of a Phase III prototype tablet formulation selected from Parts 1 and 2 of the study with the Phase II tablet formulation (both administered 30 minutes after the start of a low fat meal) at dose level B and to investigate the PK of the Phase III prototype formulation administered in the fasted state.

Being tested
GDC-0810 Phase II Tablet, GDC-0810 Phase III Prototype Tablet

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GDC-0810 Phase II Tablet and GDC-0810 Phase III Prototype Tablet 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 4 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 22 Aug 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 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?

Maximum Observed Plasma Concentration (Cmax) of GDC-0810 (time frame: Pre-dose (1 hour before dosing), 0.5, 1, 2, 3, 4, 6, 8, 12, 16 hours post-dose on Day 1, 24 and 36 hours post-dose (Day 2), 48 hours post-dose (Day 3) of each treatment period). The study lists 12 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 22 Aug 2017.
