A Study Evaluating Trastuzumab Emtansine Plus Pertuzumab Compared With Chemotherapy Plus Trastuzumab and Pertuzumab for Participants With Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Breast Cancer
Study Details
Study Description
Brief Summary
This is a randomized, multicenter, open-label, two-arm study in treatment-naive participants with operable, locally advanced, or inflammatory, centrally-assessed HER2-positive early breast cancer (EBC) whose primary tumors were greater than or equal to (>/=) 2 centimeters (cm). The study was designed to evaluate the efficacy and safety of trastuzumab emtansine + pertuzumab (experimental arm; T-DM1 + P) versus chemotherapy, trastuzumab + pertuzumab (control arm; TCH + P). The study comprised a neoadjuvant treatment period, followed by surgery, and an adjuvant treatment period.
Treatment can be stopped due to disease recurrence, unacceptable toxicity, withdrawal of consent, or study termination.

Outcome Measures
Primary Outcome Measures
- Percentage of Participants With Total Pathological Complete Response (tpCR) Assessed Based on Tumor Samples [Pre-surgery (within 6 weeks after neoadjuvant therapy; up to approximately 6 months)]
tpCR was assessed by local pathology review on samples taken at surgery following completion of neoadjuvant therapy. tpCR was defined as the absence of any residual invasive cancer on hematoxylin and eosin evaluation of the resected breast specimen and all sampled ipsilateral lymph nodes ( that is [i.e.], ypT0/is, ypN0 in the American Joint Committee on Cancer [AJCC] staging system, 7th edition). Percentage of participants with tpCR was reported.
Secondary Outcome Measures
- Overall Survival [From randomization until death (up to approximately 47 months)]
Overall survival in the overall study population was defined as the time from the date of randomization to the date of death from any cause. 3 years OS event-free rate per randomized treatment arms in the ITT population were estimated using the Kaplan-Meier method and estimated the probability of a patient being event-free after 3 years after treatment.
- Percentage of Participants Who Received Breast-Conserving Surgery (BCS) [Surgery performed after completion of neoadjuvant therapy (approximately 6 months after neoadjuvant period)]
BCS rate was defined as the percentage of participants who achieve BCS out of the ITT population of participants without inflammatory breast cancer.
- Event-Free Survival [From randomization up to disease progression or recurrence or death (up to approximately 47 months)]
Event-free survival (EFS) is defined as the time from randomization to disease progression or disease recurrence (local, regional, distant, or contralateral, invasive or non-invasive), or death from any cause. 3 years EFS rate per randomized treatment arms in the ITT population were estimated using the Kaplan-Meier method and estimated the probability of a patient being event-free after 3 years after treatment.
- Invasive Disease-free Survival (IDFS) [From surgery to the first documented occurrence of IDFC event (up to approximately 47 months)]
IDFS is defined only for participants who undergo surgery. IDFS is defined as the time from surgery to the first documented occurrence of an IDFS event, defined as: Ipsilateral invasive breast tumor recurrence; Ipsilateral local-regional invasive breast cancer recurrence; Distant recurrence; Contralateral invasive breast cancer; and death from any cause. 3 years of IDFS event-free rate per randomized treatment arms in the ITT population were estimated using the Kaplan-Meier method and estimated the probability of a patient being event-free after 3 years after treatment.
- Percentage of Participants by Response for Neuropathy Single Item [Baseline,Cycle(C) 3,C5 of neoadjuvant period (each C=21 days); pre-surgery visit (within 6weeks after neoadjuvant therapy; up to approx 6months), C4 & 8 of Adjuvant Period (each C=21 days), End of Treatment, Follow up 2 & 4 (approx 47 months)]
Participants answered the question "Did you have tingling hands/feet?", from the Modified Quality of Life Questionnaire Breast Cancer 23 (mQLQ-BR23), on a 5-point scale (1 'Not at all', 2 'A little', 3 'Somewhat', 4 'Quite a bit', 5 'Very much'). Percentage of participants by each response was reported.

All valid GHS/QoL questionnaires of the neoadjuvant phase including surgery were used. Participants without deterioration were censored at the time of completing the last GHS/QoL plus 1 day. Median time to deterioration was estimated with Kaplan-Meier method. The 95% confidence interval (CI) for the median was computed using the method of Brookmeyer and Crowley.

Title | Percentage of Participants With a Clinically Meaningful Deterioration in Global Health Status (GHS)/Quality of Life (QoL) Score |
---|---|
Description | Participants rated their quality of life (global health status) on European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ- C30), with total scores ranging from 0 (worst) to 100 (best); where higher score indicates better quality of life. Clinically meaningful deterioration in GHS/QoL was defined as a decrease in score of 10 points in GHS/QoL. |
Time Frame | From Baseline (Day 1 Cycle 1) to Cycle 6 (each cycle = 21 days) in neoadjuvant period |
Outcome Measure Data
Analysis Population Description |
---|
The Intent-to-treat (ITT) Population comprised all randomized participants, whether or not they received any study treatment or completed a full course of study treatment. Participants were analyzed according to their randomized treatment. As per protocol, the analysis for this outcome measure was focused on the neoadjuvant period only. |

Participants received pertuzumab 840 mg (loading dose) and 420 mg (maintenance dose) IV infusion followed by trastuzumab 8 mg/kg (loading dose) and 6 mg/kg (maintenance dose) IV infusion q3w for rest of the cycles (12 cycles) in adjuvant period (up to a total of 18 cycles). | Participants received pertuzumab 840 mg (loading dose) and 420 mg (maintenance dose) IV infusion followed by trastuzumab emtansine 3.6 mg/kg IV infusion q3w for a total of 18 cycles (6 cycles of neoadjuvant period and 12 cycles of adjuvant period). |

Title | Time to Clinically Meaningful Deterioration in GHS/QoL Score |
---|---|
Description | Participants rated their quality of life (global health status) on EORTC QLQ C-30, with total scores ranging from 0 (worst) to 100 (best); where higher score indicates better quality of life. Time to deterioration was defined as the time from baseline to first 10-point (or greater) decrease as measured by GHS/QoL. All valid GHS/QoL questionnaires of the neoadjuvant phase including surgery were used. Participants without deterioration were censored at the time of completing the last GHS/QoL plus 1 day. Median time to deterioration was estimated with Kaplan-Meier method. The 95% confidence interval (CI) for the median was computed using the method of Brookmeyer and Crowley. |
