About this study

Official title: An Open-Label, Phase I Study of GDC-0927 in Postmenopausal Women With Locally Advanced or Metastatic Estrogen Receptor Positive Breast Cancer

This is an open-label, dose-finding, safety, pharmacokinetics (PK), and evidence-of-activity study of GDC-0927 in postmenopausal women with locally advanced or metastatic Estrogen Receptor Positive (ER+) Human Epidermal Growth Factor Receptor 2 (HER2) breast cancer. The study will be conducted in two parts: Dose escalation and Dose expansion. During dose escalation, GDC-0927 will be administered orally as a single dose on Day -7 for PK evaluation during the lead-in period. Depending on safety and tolerability, participants will be assigned sequentially to escalating doses of GDC-0927 using standard 3+3 design. During dose expansion, there will be no PK week lead-in period. All participants will be treated until disease progression, unacceptable toxicity, participant withdrawal of consent or study termination.

Study groupRoleWhat they receive
Part I: Dose Escalation - GDC-0927ExperimentalParticipants will receive GDC-0927 orally as a single dose on Day -7. Continuous daily dosing will commence on Day 1. Depending on safety and tolerability, participants will be assigned sequentially to escalating doses of GDC-0927 with use of a standard 3 + 3 design. The starting dose will be 600 milligrams per day (mg/day), followed by dose escalation in 400 milligrams (mg) increments.
Receives: Drug: GDC-0927
Part II: Dose Expansion - GDC-0927ExperimentalParticipants in the expansion cohorts will receive GDC-0927 at MTD/RP2D starting from Day 1 of Cycle 1 (cycle length: 28 days) up to disease progression, unacceptable toxicity, participant withdrawal of consent or study termination.
Receives: Drug: GDC-0927

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GDC-0927 in people with Breast Cancer, run by Genentech, Inc. at 13 sites in 2 countries.

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 12 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 5 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in Spain, 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?

Maximum Tolerated Dose (MTD)/Recommended Phase II Dose (RP2D) of GDC-0927 (time frame: Day-7 through Cycle 1 (cycle length: 28 days)). 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 5 Oct 2020.
