Outcome Measures

Primary Outcome Measures :
  1. The population mean change from baseline in GFS (Growth Factor Signature) score [ Time Frame: Baseline and Day 15 ]

Secondary Outcome Measures :
  1. The population mean change from baseline in Ki67 among participants receiving ridaforolimus/dalotuzumab combination therapy [ Time Frame: Baseline and Day 15 ]
  2. The correlation between change in Ki67 expression and change in GFS after two weeks of treatment with ridaforolimus/dalotuzumab (MK-8669/MK-0646) combination therapy, ridaforolimus (MK-8669) monotherapy and/or dalotuzumab (MK-0646) monotherapy [ Time Frame: Baseline and Day 15 ]
