PRIMARY outcome

Timeframe: 6 months

Population: Data were not collected, study never advanced to Phase II.

6 month progression-free survival rate (PFS6) determined by tumor assessments, clinical tests and laboratory tests

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Day 28 (+/- 3) of even-numbered treatment cycles until progression

Population: Data not collected

Objective response rate determined by tumor assessments, clinical tests and laboratory tests.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: During study treatment, up to 2 years

Population: Data not collected

Determined by clinical and laboratory tests, and adverse events (AE) assessments

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: No time limit

Population: Data not collected

PTEN expression associated with better PFS determined by laboratory tests.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: No time limit

Population: Data not collected: study was terminated early due to dose limiting toxicities.

Greater reduction in PI3K-pathway signaling associated with better PFS determined by laboratory tests and tumor assessments.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: No time limit

Population: Data not collected

Responding tumors lack gene expression signatures of PI3K pathway activation, and progressing tumors demonstrate gene expression signatures of PI3K pathway activation - determined by laboratory tests and tumor assessments.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: No time limit

Population: Data not collected

Responding tumors lack gene expression signatures of MAPK pathway activation, and progressing tumors demonstrate gene expression signatures of MAPK pathway activation - determined by laboratory tests and tumor assessments.
