Purpose
This is a two-part study that will determine, if: 1) the combination of ridaforolimus and dalotuzumab will improve progression-free survival compared to exemestane; and 2) the combination of ridaforolimus and dalotuzumab will improve progression-free survival compared to both ridaforolimus and dalotuzumab as single agents, in participants with breast cancer.

Primary Outcome Measures:
- Progression free survival (PFS) [ Time Frame: Assessed every 8 weeks until documentation of disease progression or death. ] [ Designated as safety issue: No ]Progression free survival is defined as the time from randomization to progressive disease or death, which ever occurs earlier.
Secondary Outcome Measures:
- Objective response rate (ORR) [ Time Frame: Assessed every 8 weeks until documentation of disease progression or death. ] [ Designated as safety issue: No ]Objective response rate (ORR) will be estimated by the proportion of patients who achieve partial response (PR) or complete response (CR) per Response Evaluation Criteria In Solid Tumors (RECIST) 1.1
- Overall survival (OS) [ Time Frame: Every 3 months after participants go off active treatment ] [ Designated as safety issue: No ]Overall survival is defined as the time from randomization to death due to any cause.

| Arms | Assigned Interventions |
|---|---|
|
Experimental: Part A: ridaforolimus + dalotuzumab
Approximately 15 patients will be enrolled to the ridaforolimus-dalotuzumab combination treatment arm. Subsequent Patients are randomly assigned in a 1:1 ratio to treatment with the ridaforolimus (20 mg daily five days a week)/dalotuzumab (intravenous infusion 10 mg/kg once weekly) combination therapy or cross-over to exemestane single-therapy treatment.
|
Drug: ridaforolimus + dalotuzumab
Ridaforolimus 20 mg once daily (QD) five days a week, with the possibility of escalation to 30 mg once daily (QD) after the first cycle and dalotuzumab intravenous infusion 10 mg/kg once weekly (QW). Treatment will continue until disease progression.
Other Name: MK-8669, MK-0646
|
|
Active Comparator: Part A: exemestane
Exemestane 25 mg daily; single-agent therapy.
|
Drug: exemestane
Exemestane 25 mg daily (QD). Treatment will continue until disease progression. Patients may cross-over to the combination therapy after disease progression at the discretion of the investigator with Sponsor approval.
|
|
Experimental: Part B: ridaforolimus + dalotuzumab
Patients are randomly assigned in a 1:1 ratio to treatment with the ridaforolimus (20 mg daily five days a week)/dalotuzumab (intravenous infusion 10 mg/kg once weekly) combination therapy or cross-over to one of two single-therapy treatments (ridaforolimus alone or dalotuzumab alone). With the implementation of Amendment 3, this study arm will not be opened.
|
Drug: ridaforolimus + dalotuzumab
Ridaforolimus 20 mg once daily (QD) five days a week, with the possibility of escalation to 30 mg once daily (QD) after the first cycle and dalotuzumab intravenous infusion 10 mg/kg once weekly (QW). Treatment will continue until disease progression.
Other Name: MK-8669, MK-0646
|
|
Experimental: Part B: ridaforolimus
Ridaforolimus; 40 mg daily five days a week, single-agent therapy. With the implementation of Amendment 3, this study arm will not be opened.
|
Drug: ridaforolimus
Ridaforolimus 40 mg QD five days a week. Treatment will continue until disease progression. Patients may cross-over to the combination therapy after disease progression at the discretion of the investigator with Sponsor approval. Note: the Sponsor-recommended dose of ridaforolimus when administered as a single agent is 40 mg/day, but when given in combination with dalotuzumab, it is given at 30 mg/day.
Other Name: MK-8669
|
|
Experimental: Part B: dalotuzumab
Dalotuzumab intravenous infusion 10 mg/kg weekly; single-agent therapy. With the implementation of Amendment 3, this study arm will not be opened.
|
Drug: dalotuzumab
Dalotuzumab intravenous infusion 10 mg/kg QW. Treatment will continue until disease progression. Patients may cross-over to the combination therapy after disease progression at the discretion of the investigator with Sponsor approval.
