Brief summary

This study will be a single center, open-label, 2-period, fixed-sequence, Phase 1 drug-drug interaction study in healthy subjects. The primary purpose of this study is to evaluate the effect of itraconazole on the PK of ipatasertib and its primary metabolite (G-037720).

Interventions

DRUGIpatasertib

Ipatasertib 100 mg tablet orally once daily.

DRUGItraconazole

Itraconazole 100 mg capsules orally once daily.

Inclusion criteria

* Within body mass index (BMI) range 18.5 to 32.0 kg/m2, inclusive * In good health, determined by no clinically significant findings from medical history, 12-lead ECG, and vital signs * Clinical laboratory evaluations (including chemistry panel \[fasted at least 8 hours\], hematology, and urinalysis \[UA\] with complete microscopic analysis within the reference range for the test laboratory, unless deemed not clinically significant by the Investigator) * Negative test for selected drugs of abuse at Screening (does not include alcohol) and at Check-in (Day -2) * Negative hepatitis panel (hepatitis B surface antigen and hepatitis C virus antibody) and negative human immunodeficiency virus (HIV) antibody screens

Exclusion criteria

* Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, GI, neurological, or psychiatric disorder (as determined by the Investigator) * History of diabetes requiring insulin or fasting glucose ≥160 mg/dL * History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the Investigator * history of stomach or intestinal surgery or resection, or other GI disorder that would potentially alter absorption and/or excretion of orally administered drugs, except that appendectomy, hernia repair, and/or cholecystectomy will be allowed * history or presence of an abnormal ECG, which, in the Investigator's opinion, is clinically significant

Primary

MeasureTime frameDescription
Maximum Observed Plasma Concentration (Cmax) of ipatasertib and its Metabolite (G-037720)Pre-dose, 0.167, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, 144 hours post dose on Day 1 and 19; 168, 192 hours post dose on Day 19Cmax is the maximum observed concentration.
Area Under the Plasma Concentration-Time Curve From Time Zero to Extrapolated Infinite Time (AUC[0-inf]) of Ipatasertib and its Metabolite (G-037720)Pre-dose, 0.167, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, 144 hours post dose on Day 1 and 19; 168, 192 hours post dose on Day 19AUC(0-inf) is the area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). AUC is a measure of the plasma concentration of a drug over time.
Area Under the Plasma Concentration-Time Curve From Hour 0 to the Last Measureable Concentration (AUC0-t) of Ipatasertib and its Metabolite (G-037720)Pre-dose, 0.167, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, 144 hours post dose on Day 1 and 19; 168, 192 hours post dose on Day 19Area Under the Plasma Concentration-Time Curve From Hour 0 to the Last Measureable Concentration (AUC0-t) will be reported.

Secondary

MeasureTime frameDescription
Number of Participants Who Experienced at Least 1 Adverse EventUp to 28 days after the last dose of the study drug (approximately up to 51 days)An adverse event is any untoward medical occurrence in a patient 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.
