Detailed Description

The study is a double-blind, randomized Phase 2 trial of Exemestane +/- MM-121. The trial is designed to demonstrate whether MM-121 + Exemestane is more effective than Exemestane alone in ER+ and/or PR+ and Her2 negative breast cancer patients that have failed first-line anti-estrogen therapy in the locally advanced or metastatic setting and patients that have progressed during (or within 6 months of completing) adjuvant treatment with a non-steroidal aromatase inhibitor (AI)and/or tamoxifen. Patients will be treated until radiologic or clinical progression of their disease is documented. Local radiologist and/or PI assessment is accepted.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Progression Free Survival (PFS)
Time Frame: Time from first dose to date of progression, the longest time frame of 79.1 weeks
To determine whether MM-121 + exemestane was more effective than placebo + exemestane in prolonging progression-free survival. PFS was a time to event measure, and progression of disease is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), "as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions". Progression free survival was defined as the number of months from the date of randomization to the date of death or progression. If neither death nor progression was observed during the study, PFS data was censored at the last non-progressive disease valid tumor assessment unless the patient was discontinued due to symptomatic deterioration. If this occurred, the patient was counted as having progressive disease (PD).
Time from first dose to date of progression, the longest time frame of 79.1 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Survival
Time Frame: Time from first dose to date of death, over approximately 2 years
To determine whether MM-121 + exemestane is more effective than placebo + exemestane in prolonging overall survival. This was a time-to-event analysis of time from first dose to date of death.
Time from first dose to date of death, over approximately 2 years
