Neoadjuvant Treatment With Nab-paclitaxel for Patients With Stage II and III Luminal Breast Cancer
Phase II, Open-label, Non-randomized Study of Nab-paclitaxel for the Neoadjuvant Treatment of Patients With Stage II and III Luminal Breast Cancer
Study Overview
Detailed Description
The primary objective of the trial is to determine the percentage of patients with poor response [residual cancer burden III (RCB-III) rate] in contrast to good response [residual cancer burden 0/I RCB-0/1] measured by the Symmans criteria [20] at surgery, in patients with stage II-III luminal breast cancer treated with neoadjuvant nab-paclitaxel.
The primary endpoint of the study is to determine the residual cancer burden grade III (RCB-III) after surgery.
The total number of patients to be included in this study is 78 patients.
The duration of the study, from first patient visit to last patient visit will be approximately 90 months (Including follow-ups)

Exclusion Criteria:

- Synchronous contralateral or multicentric breast cancer.
- Clinical or radiologic evidence of metastatic disease. Chest examination by x-ray or CT-scan, abdominal examination by CT-scan, bone examination by bone scan as well as other radiological methods in case of suspicion must be performed before enrollment in order to rule out metastasis.
- Second primary malignancy, except adequately treated carcinoma in situ of the cervix, stage I colon cancer, non-invasive melanoma, basal or squamous cell carcinomas of the skin, ipsilateral ductal carcinoma in-situ (DCIS) of the breast and lobular carcinoma in-situ (LCIS) of the breast; unless that prior malignancy was diagnosed and definitively treated more than 5 years ago with no subsequent evidence of recurrence.
- Prior or concurrent anti-cancer therapy for current disease (hormone therapy, chemotherapy, radiotherapy, immunotherapy, biological therapy other than the trial therapies).
- Concurrent treatment with any hormonal treatment either for osteoporosis or as replacement therapy.
- Patients with known hypersensitivity to nab-paclitaxel or any of its components.
- Previous neuropathy grade >1 according to the NCI-CTCAE vs 4.03 criteria

- Have any serious concomitant systemic disorder incompatible with the study (at the discretion of investigator).
- Patient is pregnant or breast feeding or planning to become pregnant within the six months after the end of treatment. Women with child-bearing potential must be performed a pregnancy serum or urine testing within 7 days prior to study entry according to institutional standards and should use an adequate non-hormonal contraceptive method (intra-uterine contraceptive device, barrier method of contraception in conjunction with spermicidal jelly or surgically sterilized) during treatment with study drugs and within the six months after the end of treatment.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The Residual Cancer Burden Grade III (RCB-III).
Time Frame: After surgery, up to 4 months
|
The RCB-III was reported, including a 95% confidence interval. The estimate of the RCB-III was calculated as follows: Overall Response Rate = Number of patients with RCB-III / Intent to treat (ITT) population |
After surgery, up to 4 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pathologic Complete Response (pCR) Rate
Time Frame: After surgery, up to 4 months
|
Objective Response was measured following the Response Evaluation Criteria In Solid Tumors (RECIST 1.1) criteria. For the purpose of this study a response is defined as the achievement of a complete or partial response measured by breast MRI. Pathological complete response (pCR) was evaluated following the Symmans method at the time of the definitive surgery. For the purpose of this study RCB-0 was considered a pCR. The pCR (RCB-0) rate (pCRR) was reported including a 95% confidence interval. The estimate of the pCR rate was calculated as follows by central laboratory: pCR Rate = Number of patients with pCR / ITT population. |
After surgery, up to 4 months
|
Objective Response Rate (ORR) by Magnetic Resonance Imaging (MRI)
Time Frame: After surgery, up to 4 months
|
The ORR was reported including a 95% confidence interval. The estimate of the ORR was determined according to RECIST 1.1 and measured by MRI and mammogram in patients treated with this regimen. ORR was calculated as follows: Overall Response Rate = Number of Complete Responses (CRs), Partial Responses (PRs) / ITT population |
After surgery, up to 4 months
|
Objective Response Rate (ORR) by Mammogram
Time Frame: After surgery, up to 4 months
|
The ORR was reported including a 95% confidence interval. The estimate of the ORR was determined according to RECIST 1.1 and measured by MRI and mammogram in patients treated with this regimen. ORR was calculated as follows: Overall Response Rate = Number of CRs, PRs / ITT population |
After surgery, up to 4 months
|
Invasive Disease Free Survival (IDFS)
Time Frame: Up to 6 years
|
IDFS was defined as the time (days) from the date of randomization until the date of objective recurrent disease (local, regional or distant), second primary invasive malignancy (breast or non-breast) or death from any cause.
For patients not known to have died as of the data cut-off date and who do not have recurrent disease or second primary tumor, invasive disease-free survival will be censored at the last contact date.
Ductal carcinoma in-situ (DCIS) will not be considered an event for the purpose of this analysis.
|
Up to 6 years
|
Rate of Conversion to Breast Conserving Surgery (BCS)
Time Frame: After surgery, up to 4 months
|
The conversion from the initially planned mastectomy to BCS was reported including a 95% confidence interval. The estimate of the rate of conversion to BCS was calculated as follows: BCS rate = Number of patients with BCS / Number of patients with initially planned mastectomy. |
After surgery, up to 4 months
|
The Number of Participants Who Experienced Adverse Events (AE)
Time Frame: During treatment and until 30 days after the last dose of each patient study treatment
|
Incidence of adverse events by maximum CTCAE grade (v4.03;
NCI 2010) that occur during the study treatment period or within 30 days of the last dose of study treatment, regardless of causality and according to the relationship to study drug as assessed by the investigator, were collected and evaluated.

During treatment and until 30 days after the last dose of each patient study treatment

|
Baseline visit
|
Caveolin-1 in Pre-treatment Tumor Samples as Tumor Predictive Marker of Nab-paclitaxel Response
Time Frame: Baseline visit

Caveolin (Cav)-1 was evaluated in the stroma and its expression was categorized in low, moderate, or high (tertile).
The high expression of Cav-1 was considered as positive.
|
Baseline visit
|
Secreted Protein, Acidic, Cysteine-rich (SPARC) in Pre-treatment Tumor Samples as Tumor Predictive Marker of Nab-paclitaxel Response
Time Frame: Baseline visit
|
SPARC was evaluated for both tumor and stroma.
Its expression was categorized as negative when the intensity was absent-to-weak (1), or moderate (11)-to-strong (111) with a proportion of stained cells <10%.
Immunolabeling was positive if the intensity was moderate (11)-to-strong (111) and the extent of staining was 10%.
