Brief Summary
To evaluate the preliminary activity and pharmacokinetics of 2 separate doses and schedules of orally administered Temsirolimus (CCI-779) given in combination with daily letrozole, compared to letrozole alone, in the treatment of locally advanced or metastatic breast cancer in postmenopausal women. All patients must be appropriate to receive endocrine therapy as treatment for advanced disease.

Outcome Measures
Primary Outcomes (1)
Percentage of Participants With Objective Response (OR)
OR measured as Complete response (CR) or Partial response (PR) confirmed by assessments performed no less than 4 weeks after the criteria for the response are first met. CR=disappearance of all target and non-target lesions with normalization of tumor marker level; PR=at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, referencing the screening sum LD. Target lesions=all measurable lesions up to 5 lesions per organ (10 lesions in total), representative of all involved organs, if possible; recorded and measured at screening. Non-target lesions=all other lesions.
Baseline, every 4 cycles (1 cycle is defined as a 14 day duration) up to Cycle 25, then every 6 cycles until disease progression
Secondary Outcomes (11)
Percentage of Participants With Best Overall Response (Clinical Benefit)
Baseline, every 4 cycles (1 cycle is defined as a 14 day duration) up to Cycle 25, then every 6 cycles until disease progression)
Time to Disease Progression
Baseline, every 4 cycles (1 cycle is defined as a 14 day duration) up to Cycle 25, then every 6 cycles until disease progression)
Time to Treatment Failure
Baseline until Progressive disease, death, or discontinuation of study treatment
Percentage of Participants Exhibiting Freedom From Progression
Baseline, 8 weeks, 6 months, 12 months, and 24 months
Duration of Response
Baseline, every 4 cycles (1 cycle is defined as a 14 day duration) up to Cycle 25, then every 6 cycles until disease progression)
- +6 more secondary outcomes

Eligibility Criteria
You may qualify if:
- Postmenopausal women with histologically confirmed, measurable locally advanced disease or metastatic breast.
- Must be appropriate to receive endocrine therapy as treatment for advanced disease (chemotherapy; prior adjuvant therapy with antiestrogens other than aromatase inhibitors; prior adjuvant or first-line metastatic therapy with tamoxifen or trastuzumab, are permitted).
- Women may either present with de novo advanced or metastatic cancer, or have had tumor progression while receiving adjuvant tamoxifen or at any time after completing adjuvant tamoxifen, or have had tumor progression while receiving first-line metastatic therapy with tamoxifen.
You may not qualify if:
- Patients having known central nervous system (CNS) metastases.
- Prior therapy with Temsirolimus (CCI-779) or aromatase inhibitors.
- Tamoxifen, or other hormonal therapy, in the metastatic or adjuvant setting within 1 week prior to day 1 of treatment on study.

Limitations and Caveats
Clinical development of oral temsirolimus for treatment of locally advanced or metastatic breast cancer was terminated by Wyeth based on the results of a phase 3 clinical study with the combination temsirolimus and letrozole.
