Outcomes

Primary Outcome Measures

Number of Participants of Clinically Relevant Toxicities (CRT)
Clinically relevant toxicities will include the composite incidence of grade 3 or higher non-hematologic toxicity, grade 2 or higher neurotoxicity, and grade 4 or higher hematologic toxicity. These toxicities will only be assessed at the pre-specified toxicity-assessment visits. In addition, the following events, regardless of timing of their occurrence, will also count towards the composite endpoint: febrile neutropenia, any toxicity requiring dose-delay, discontinuation of any study treatment (Paclitaxel, Trastuzumab, or T-DM1) for toxicity, and any serious adverse event (SAE).
3-year Disease Free Survival (DFS) Rate of Trastuzumab Emtansine (TDM-1)
Disease-free survival (DFS) is evaluated and defined per protocol: from the time of randomization until the to the occurrence of the first of the following events: Local/regional recurrence: a recurrent or new invasive ipsilateral breast cancer, invasive breast cancer in the axilla, regional lymph nodes, chest wall, or skin of the ipsilateral breast. Contralateral invasive breast cancer, Distant recurrence: metastatic disease that has either been biopsy confirmed or clinically diagnosed as recurrent invasive breast cancer. A single new lesion on a bone scan without evidence of lytic disease on x-ray and without symptoms does not in and of itself constitute distant recurrence, but multiple new bone lesions, or increased isotope uptake associated with new bone symptoms are more likely due to metastases. Bone metastases must be documented with x-rays and clinical description. Death from any cause

Secondary Outcome Measures

5. Study Description

Brief Summary
This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is still being studied and that research doctors are trying to find out more about it-such as the safest dose to use, the side effects it may cause, and if the drug is effective for treating different types of cancer. It also means that the FDA has not approved this drug for use patients undergoing adjuvant treatment for HER2+ breast cancer. Trastuzumab emtansine (T-DM1) is a drug that may stop cancer cells from growing. This drug has been used in other research studies and information from those other research studies suggests that this drug may help to prevent the recurrence of breast cancer in this research study. The use of T-DM1 in this research study is experimental, which means it is not approved by any regulatory authority for the adjuvant treatment of HER2-positive breast cancer. However, it FDA-approved for metastatic HER2-positive breast cancer. T-DM1 has caused cancer cells to die in laboratory studies. In preclinical studies, this drug has prevented or slowed the growth of breast cancer. The breast cancer treatments (paclitaxel and Trastuzumab) used in this study are considered part of standard-of-care regimens in early breast cancer. A standard treatment means that this is a treatment that would be accepted by the majority of the medical community as a suitable treatment for your type of breast cancer. In this research study, the investigators are looking to see if the study drug T-DM1 will have less side effects than traditional HER2-positive breast cancer treatment of trastuzumab and paclitaxel. The investigators are also hoping to learn about the long term benefits and disease-free survival of participants who take the study drug T-DM1 in comparison to those participants to take the combination of trastuzumab and paclitaxel.
Detailed Description
If a participant agrees to participate in this study she will be asked to undergo some screening tests or procedures to confirm that she is eligible. Many of these tests and procedures are likely to be part of regular cancer care and may be done even if turns out that she does not take part in this research study. If she has had some of these tests or procedures recently, they may or may not have to be repeated. These tests and procedures will include: a medical history, performance status, assessment of your tumor, blood tests, cardiac tests, pregnancy test and a collection of tumor tissue. If these tests show that she is eligible to participate in the research study, she will begin the study treatment. If she does not meet the eligibility criteria, she will not be able to participate in this research study. Because no one knows which of the study options is best, the participant will be "randomized" into one of the study groups after she has had her breast surgery: Group 1 or Group 2. Randomization means that she is put into a group by chance. Neither the participant nor the research doctor will choose what group she will be in. The participant will have a one in three chance of being placed in any group. Approximately 375 study participants will receive the study drug, while 125 study participants will receive the standard therapy of trastuzumab and paclitaxel. Group 1 participants will receive the study drug T-DM1 every three weeks by IV (intravenous injection) for 17 treatments (total of 51 weeks). Group 2 participants will receive the FDA-approved drugs Paclitaxel and Trastuzumab once per week by IV for 12 weeks. Then beginning week 13, participants will receive Trastuzumab only by IV injection every three weeks for the next 13 treatments. During all cycles the participant will have a physical exam and tumor assessment. The investigators would like to keep track of the participant's medical condition for the next five years after the final dose of study drug. The investigators would like to do this by regular visits every 6 months for 3 years after completion of study treatment, and then once a year for the next two years. The investigators may ask for additional follow-up by phone after completion of these visits. Participants who undergo lumpectomy (breast conserving surgery) need to receive breast radiation therapy to participate in this study. Participants who have undergone a mastectomy may receive chest wall and lymph node radiation (as determined by discussion with their physician). Radiation Therapy will begin after the conclusion of all study paclitaxel doses, and after 12 weeks fo the study drug T-DM1.

Title
Number of Patients Have Alopecia
Description
alopecia assessment is a 5-item questionnaire that will assess the impact alopecia has had on these patients and will be conducted electronically at pre-specified study visits. If electronic evaluation is not possible, paper evaluation will be conducted.
Time Frame
Median follow-up was 3.9 years. The AE data cutoff date is 21 April 2020.
Title
3-year T-DM1 iDFS Percentage by Tumor Size and Hormone Receptor (HR) Status
Description
Disease-free survival (DFS) is evaluated in patients treated with trastuzumab emtansine, which is defined per protocol: from the time of randomization until the to the occurrence of the first of the following events: Local/regional recurrence: a recurrent or new invasive ipsilateral breast cancer, invasive breast cancer in the axilla, regional lymph nodes, chest wall, or skin of the ipsilateral breast. Contralateral invasive breast cancer, Distant recurrence: metastatic disease that has either been biopsy confirmed or clinically diagnosed as recurrent invasive breast cancer. A single new lesion on a bone scan without evidence of lytic disease on x-ray and without symptoms does not in and of itself constitute distant recurrence, but multiple new bone lesions, or increased isotope uptake associated with new bone symptoms are more likely due to metastases. Bone metastases must be documented with x-rays and clinical description. Death from any cause
Time Frame
3 years
Title
Number of Incidence of Grade 3-4 Cardiac Left Ventricular Dysfunction
Description
All grade 3 - 4 adverse events (AE) with treatment attribution of possibly, probably or definite based on CTCAEv4 as reported on case report forms were counted. Incidence is the number of patients experiencing at least one treatment-related grade >=3 AE of any type during the time of observation
Time Frame
AE is reported every 3 weeks for the first 12 weeks, then every 9 weeks for the subsequent 39 weeks, then follow-up up to 5 years after completion of study treatment or until death, whichever occurs first. Median follow-up 3.1 years.
Title
Number of Incidence of T-DM1 Induced Grade 2-3 Thrombocytopenia
Description
Reversible Grade 1-4 thrombocytopenia has been observed in ongoing studies with trastuzumab emtansine.
Time Frame
AE is reported every 3 weeks for the first 12 weeks, then every 9 weeks for the subsequent 39 weeks, then follow-up up to 5 years after completion of study treatment or until death, whichever occurs first. Median follow-up 3.1 years.
Title
Number of SNPs With Top Associations of Trastuzumab Emtansine-induced Grade 2-4 Thrombocytopenia in the T-DM1 Arm
Description
DNA will be genotyped for SNPs and CNV markers using the Infinium Human Omni1 array (1.2 million SNP platform) from Illumina. A gene-based association analyses for thrombocytopenia or bleeding is applied with significancy (p-value). This analysis was only conducted in the T-DM1 arm.
Time Frame
DNA sample collected at pre-treatment. AE is reported every 3 weeks for the first 12 weeks, then every 9 weeks for the subsequent 39 weeks.
Title
Percentage of Patients With Amenorrhea
Description
All grade 3 - 4 adverse events (AE) with treatment attribution of possibly, probably or definite based on CTCAEv4 as reported on case report forms were counted. Incidence is the number of patients experiencing at least one treatment-related grade >=3 AE of any type during the time of observation. For those who were premenopausal pre-chemotherapy, at each follow-up visit (every six months) in order to assess for duration of amenorrhea and also premature ovarian failure.
Time Frame
Surveys are took at month 6 and 12 during treatment, and month 18, 24, 30 and 36 during follow up.
Title
Gene Mutation Assessed Using High-throughput Mutation Profiling System (Oncomap)
Description
Archival tumor tissue from all patients will be assessed using a high-throughput mutation profiling system (Oncomap) to query a large panel of cancer gene mutations.
