NCT Number: NCT01896531
This multicenter, randomized, double-blind, placebo-controlled study will evaluate the efficacy of ipatasertib in combination with oxaliplatin, 5-fluorouracil, and leucovorin (modified FOLFOX6 [mFOLFOX6]) chemotherapy in participants with advanced or metastatic gastric or gastroesophageal junction (GEJ) cancer. Participants will be randomized to receive either ipatasertib or placebo orally daily on Days 1 to 7 of each 14-day cycle in combination with mFOLFOX6 on Day 1 of each cycle.

Exclusion criteria
Participants will receive bolus and infusional 5-fluorouracil on Day 1 of each 14-day cycle (as a part of mFOLFOX6 therapy), until disease progression or unacceptable toxicity. The infusion times for infusional 5-fluorouracil may be determined per local and/or institutional standards and product labeling.
Participants will receive ipatasertib, 600 milligrams (mg) orally once daily on Days 1 to 7 of each 14-day cycle until disease progression or unacceptable toxicity.
Participants will receive leucovorin or equivalent substitute orally, on Day 1 of each 14-day cycle (as a part of mFOLFOX6 therapy), until disease progression or unacceptable toxicity.
Participants will receive oxaliplatin via intravenous (IV) infusion on Day 1 of each 14-day cycle (part of mFOLFOX6 therapy). Oxaliplatin will be discontinued after completion of 8 cycles
Participants will receive matching oral placebo capsules once daily on Days 1 to 7 of each 14-day cycle until disease progression or unacceptable toxicity.
Time frame: Screening, at the end of Cycle 4 (cycle = 14 days) and every fourth cycle thereafter until disease progression or death, whichever occurred first, assessed up to approximately 1.75 years
PFS was defined as the time from randomization to the first occurrence of disease progression (as determined using RECIST Version 1.1 and assessed by the investigator), or death from any cause on study. Progressive disease (PD): At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or progression of non-target lesions. Death on study was defined as death from any cause within 30 days of the last dose of study treatment regimen. Kaplan-Meier estimates were used for evaluation.
Time frame: Baseline up to end of study (up to approximately 7.5 years)
OS was defined as the time from the date of randomization to the date of death from any cause. Kaplan-Meier estimates were used for evaluation.
Time frame: Screening, at the end of Cycle 4 (cycle = 14 days) and every fourth cycle thereafter until disease progression or death, whichever occurred first, up to end of study (up to approximately 7.5 years)
Objective Response Rate was defined as the percentage of participants achieving either a complete response (CR) or a partial response (PR) based on the investigator assessment using RECIST v 1.1. CR: disappearance of all target lesions and all pathological lymph nodes below 10 mm. Partial response (PR): At least a 30% decrease in the sum of diameters of target lesions.
Time frame: Screening, at the end of Cycle 4 (cycle = 14 days) and every fourth cycle thereafter until disease progression or death, whichever occurred first, up to end of study (up to approximately 7.5 years)
Duration of objective tumor response in participants with measurable soft tissue disease at baseline was defined as the time from first observation of an objective tumor response until first observation of disease progression, as assessed by the investigator per modified RECIST Version 1.1. PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or progression of non-target lesions.
Time frame: Baseline until end of study (up to approximately 7.5 years)
An adverse event is any untoward medical occurrence in a subject 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. Death on study was defined as death from any cause within 30 days of the last dose of study treatment regimen.
Time frame: Day 1 at 1 hour and 4 hours post-dose; Day 5, pre-dose and 2 hours post-dose
