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).

| Reference capsule GDC-0134 | Drug | Oral administration of a single dose of 200 milligrams (mg) GDC-0134 reference capsule administered as two 100 mg capsules. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Area Under the Plasma Concentration-Time Curve Extrapolated to Infinity (AUC0-inf) of GDC-0134 | The AUC0-inf is calculated in a plot of concentration of drug in blood plasma against time and extrapolated to infinity. | Periods 1-4: Day 1: pre-dose, post-dose at 0.5 hours (h), 1 h, 1.5 h, 2 h, 3 h, 4 h, 6 h, 8 h, 12 h and 16 h, Day 2: post-dose 24 h and 36 h, Day 3, Day 4, Day 6, Day 8, Day 15 and Day 22 |
| Area Under the Plasma Concentration-Time Curve up to Time Tau (AUC0-t) of GDC-0134 | The AUC0-t is calculated in a plot of concentration of drug in blood plasma against time and calculated up to the time of the last measurable GDC-0134 concentration. | Periods 1-4: Day 1: pre-dose, post-dose at 0.5 hours (h), 1 h, 1.5 h, 2 h, 3 h, 4 h, 6 h, 8 h, 12 h and 16 h, Day 2: post-dose 24 h and 36 h, Day 3, Day 4, Day 6, Day 8, Day 15 and Day 22 |
| Maximum Observed Concentration (Cmax) of GDC-0134 | Cmax is the maximum observed concentration of drug in blood plasma. | Periods 1-4: Day 1: pre-dose, post-dose at 0.5 hours (h), 1 h, 1.5 h, 2 h, 3 h, 4 h, 6 h, 8 h, 12 h and 16 h, Day 2: post-dose 24 h and 36 h, Day 3, Day 4, Day 6, Day 8, Day 15 and Day 22 |
| Time to Maximum Concentration (Tmax) of GDC-0134 | Tmax is the time elapsed from the time of drug administration to maximum plasma concentration. | Periods 1-4: Day 1: pre-dose, post-dose at 0.5 hours (h), 1 h, 1.5 h, 2 h, 3 h, 4 h, 6 h, 8 h, 12 h and 16 h, Day 2: post-dose 24 h and 36 h, Day 3, Day 4, Day 6, Day 8, Day 15 and Day 22 |
| Apparent Half-Life (t1/2) of GDC-0134 | Half-life is defined as the time required for the drug plasma concentration to be reduced to half. | Periods 1-4: Day 1: pre-dose, post-dose at 0.5 hours (h), 1 h, 1.5 h, 2 h, 3 h, 4 h, 6 h, 8 h, 12 h and 16 h, Day 2: post-dose 24 h and 36 h, Day 3, Day 4, Day 6, Day 8, Day 15 and Day 22 |

| Percentage of Participants with Adverse Events | 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. |
