About this study
Official title: A Phase I/II Study of Preoperative (Neoadjuvant) Combination of Letrozole (Femara), Everolimus (Afinitor), and TRC105 in Postmenopausal Women With Newly Diagnosed Local or Locally Advanced Potentially Resectable Hormone-Receptor Positive and Her2 Negative Breast Cancer
This study will test how well a new combination of three drugs (Letrozole, Everolimus, and TRC105) is tolerated and how well it works in Stage 2 and 3 breast cancer when given prior to definitive surgery. Letrozole blocks the estrogen receptor expressed by many breast cancers while everolimus blocks signals that drive cancer cells to grow. TRC105 is an investigational drug that blocks the formation and growth of blood vessels that feed the cancer and promote its growth. The goal of this study is to investigate the safety and efficacy of this multitargeted approach in breast cancer.
Read the detailed description
In postmenopausal women with hormone receptor-positive and Her2 negative non-metastatic breast cancer, downstaging or the achievement of a complete pathologic remission before definitive surgery has been associated with the lowest risk of recurrence of breast cancer. In order to achieve a better response in these patients in the preoperative setting, this study combines 3 potentially synergistic agents. Letrozole blocks the synthesis of estrogens and, in doing so, deprives the tumor from hormones which drive its growth. Everolimus is a drug that blocks growth factor signaling which is essential for tumor cells to maintain their growth and proliferation. Everolimus has already been shown to work very well in this subtype of breast cancer in the recurrent and metastatic setting. TRC105 is an investigational agent that prevents the formation and growth of new blood vessels that support tumors by providing oxygen and nutrients.
The study has 2 components. First the investigators will determine the ideal in terms of tolerance combination of doses of the 3 agents. Once the ideal regimen is determined, more patients will be treated with the investigational combination. During this second stage, the investigators will get a preliminary idea of how effective the investigational therapy is. Further studies will need to be done to confirm the efficacy of the investigational combination.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants Who Experienced Dose-limiting Toxicities
This outcome will report the number of patients who experienced a dose-limiting Toxicity (DLT) in Phase I Cohort 1, Phase I Cohort 2, and Phase I Cohort -1. A DLT was defined as:
- A grade 3 or 4 non-hematologic toxicity except anorexia, alopecia, nausea (which is not refractory to antiemetics), fatigue, and fever without neutropenia;
- Failure to recover to baseline (except alopecia) after delaying the next dose by more than 14 days;
- Grade 3 or 4 neutropenia complicated by fever >38.5°C or infection, or grade 4 neutropenia of ≥7 days duration; or
- Grade 4 thrombocytopenia, or grade 3 thrombocytopenia complicated by hemorrhage.
The maximum tolerated dose (MTD) is defined as the highest dose at which 0 out of the first 3 or 1 out of a total of 6 patients experience DLT during the first cycle of therapy; this dose level will be the recommended phase 2 dose (RP2D) in the Phase II Group.
Measured: 4 weeks
Secondary outcomes (10)
Rates of Pathologic Complete Remission (pCR)
The 2-dimensional size of the surgically excised residual tumor was measured and compared to the radiographic size of the tumor at baseline.
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by MRI:
Complete Response (CR), Disappearance of all target lesions and reduction in short axis of any pathological lymph nodes to <10 mm; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Measured: 24 weeks up to time of surgery
C Max - Letrozole
Maximum serum concentration of Letrozole.
Measured: Day 1 and Day 29
Tumor Proliferation Changes
This outcome will report the change in tumor cell proliferation. This was measured by the change in the percentage of Ki67 positive cells from pretreatment to surgery (up to 24 weeks): (%Ki67(+) cells pretreatment - %Ki67(+) cells posttreatment)/(%Ki67(+) cells pretreatment) * 100 Ki67 is a protein found in cells that are dividing. The Ki-67 assessment was performed by the clinical histology laboratory using a validated assay. The results were evaluated by a board-certified pathologist, who estimated the proportion of cancer cells stained for Ki-67. The individual tissue sections were analyzed blindly and at the completion of the assay, results were correlated per case as to changes in Ki-67 with the investigational therapy.
Measured: 24 weeks (pretreatment to time of definitive surgery)
T Max - Letrozole
T Max is the time to the maximum serum concentration of a drug in the blood. This outcome will report the T Max of Letrozole at Day 1 in Phase 1 Cohort 1, Phase 1 Cohort 2, and Phase 2. All patients in the trial received the same dose of letrozole.
Measured: Day 1
AUC - Letrozole
This outcome will report the area under the serum concentration of letrozole versus time curve (AUC-L).
AUC-L is the integral of the concentration of letrozole in the blood as a function of time. AUC-L measures how much letrozole reaches the bloodstream in a period of time after a dose is given. This is useful in dose determination and assessing drug interactions.
This outcome was assessed on Day 1 and on Day 29 for Phase I Cohort I, Phase I Cohort 2, and Phase 2.
Measured: Day 1 and Day 29
T 1/2 - Letrozole
T ½ is the half-life of a drug in the blood. This is the time it takes for the concentration of the drug in the blood to be reduced by half. This outcome will report the T 1/2 of Letrozole.
Measured: Day 1
C Max - Everolimus
Cmax is the maximum serum concentration of a drug in the blood. This outcome will report the Cmax of Everolimus in Phase 1 Cohort 1 and Phase 1 Cohort 2 combined with Phase 2 (since the dose of everolimus was the same in these cohorts) at Day 1 and Day 29.
Measured: Day 1 and Day 29
T Max Everolimus
T Max is the time to the maximum serum concentration of a drug in the blood. This outcome will report the T Max of Everolimus in Phase 1 Cohort 1, and combined Phase 1 Cohort 2 and Phase 2 (since patients received the same dose of everolimus) at Day 1.
Measured: Day 1
AUC - Everolimus
This outcome will report the area under the serum concentration everolimus of versus the time curve (AUC-E).
AUC-E is the integral of the concentration of everolimus in the blood as a function of time. AUC-E measures how much everolimus reaches the bloodstream in a period of time after a dose is given. This is useful in dose determination and assessing drug interactions.
This outcome was assessed on Day 1 and on Day 29 for Phase I Cohort I, and combined Phase I Cohort 2 and Phase 2 (since patients in Phase I cohort 2 and Phase 2 received the same dose of everolimus).
Measured: Day 1 and Day 29
T 1/2 - Everolimus
T ½ is the half-life of a drug in the blood. This is the time it takes for the concentration of the drug in the blood to be reduced by half. This outcome will report the T 1/2 of Everolimus in Phase 1 Cohort 1 and combined Phase 1 Cohort 2 and Phase 2 at Day 1 (since patients in Phase 1 Cohort 2 and Phase 2 at Day 1 received the same dose of everolimus).
Measured: day 1

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Letrozole, Everolimus and TRC105 in people with Breast Cancer, run by University of Alabama at Birmingham at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 21 Aug 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants Who Experienced Dose-limiting Toxicities (time frame: 4 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02520063, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2026.
