Bioavailability of GDC-0134 and the Effect of Food and Proton Pump Inhibitor on Pharmacokinetics of GDC-0134 in Healthy Female Participants
February 29, 2024 updated by: Genentech, Inc.
A Phase I Open-Label Study to Determine the Relative Bioavailability of GDC-0134 and to Investigate the Effect of Food and Proton Pump Inhibitor on Pharmacokinetics of GDC-0134 in Healthy Female Subjects of Non-childbearing Potential
This study will evaluate the pharmacokinetics and safety of GDC-0134 in healthy female volunteers of non-childbearing potential.
The first part of the study will compare the bioavailability of a prototype capsule of GDC-0134 relative to an existing GDC-0134 reference capsule (Periods 1 and 2).
The second part of the study will assess the effect of GDC-0134-in-applesauce preparation under fasting conditions, the effect of low and high fat foods as well as the effect of elevated stomach pH via pre-treatment with rabeprazole, a proton pump inhibitor (PPI), under fasted and high-fat meal conditions (Periods 3 and 4).

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants with Adverse Events
Time Frame: From baseline until 21 days after the last dose of study drug up to approximately 16 weeks
|
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment.
An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product.
Preexisting conditions which worsen during a study are also considered as adverse events.
