Metastatic Breast Cancer Clinical Trial
— PyrotinibOfficial title:
A Randomized, Open-label Study of First Line Pyrotinib, Trastuzumab With an Aromatase Inhibitors, in the Treatment of HER2 Positive and HR Positive Metastatic or Inoperable Locally Advanced Breast Cancer
This study is a randomized, open-label, phase II study, comparing the efficacy and safety of trastuzumab plus aromatase inhibitors, with or without pyrotinib, in the treatment of HR (hormone receptor)+/HER2 (human epidermal growth factor receptor 2) + MBC and inoperable LABC patients.

Major surgical procedure or significant traumatic injury within 28 days prior to study treatment start or anticipation of the need for major surgery during the course of study treatment 7. Severe organ dysfunction as assessed by signs and symptoms, laboratory studies and rapid progression of disease, which leading to a clinical indication for chemotherapy. 8.

History of myocardial infarction within 6 months of randomization 10. History of LVEF decline to below 50% during or after prior trastuzumab neo-adjuvant or adjuvant therapy 11. Pregnant or lactating women; 12. QT interval>470 ms; 13. Serious concomitant diseases (including severe hypertension, severe diabetes, active infection, thyroid disease, etc.) that are harmful to the patient's safety or affect the patient's completion of the study; |

Primary | Progression-Free Survival (PFS) | PFS was defined as the time from randomization to first documented disease progression (PD) using Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) or death from any cause, whichever occurred first. For target lesions, PD was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum of the longest diameter recorded since treatment started or the appearance of 1 or more new lesions. For non-target lesions, PD was defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing non-target lesions. The PFS will be will be estimated using Kaplan-Meier method. A Kaplan-Meier curve, median PFS, hazard ratio with appropriate confidence intervals will be reported. |
From randomization to 36 month | |
Secondary | Overall Survival (OS) | Overall Survival (OS), defined as the time from the date of randomization to the date of death, regardless of the cause of death. Participants who were alive at the time of the analysis were censored at the date of the last follow-up assessment. Participants without follow-up assessment were censored at the day of last study medication and participants with no post-baseline information were censored at the date of randomization. The OS will be will be estimated using Kaplan-Meier method. A Kaplan-Meier curve, median OS, hazard ratio with appropriate confidence intervals will be reported. |
From randomization to 36 month | |
Secondary | Objective Overall Response Rate (ORR) | ORR was defined as percentage of participants with best (confirmed) overall response (BOR) of either CR or PR. ORR was assessed by the investigator according to RECIST version 1.1 and is based on BOR, which is defined as best response recorded from start of study treatment until disease progression/recurrence or death. Participants needed to have two consecutive assessments of PR or CR to be a responder. Only participants with measurable disease at baseline were included in the analysis of BOR and who did not have any evaluable post-baseline assessments were classified as not evaluable. The ORR will be reported by percentage with each arms and appropriate confidence intervals. |
From randomization to 36 month | |
Secondary | Duration of Response (DoR) | DoR is defined as date of initial confirmed PR/CR until date of progressive disease or death from any cause. PR or CR or SD is according to RECIST version 1.1. The DoR will be estimated using Kaplan-Meier method. Kaplan-Meier curves, median DoR, hazard ratio with appropriate confidence intervals will be reported. |
From randomization to 36 month | |
Secondary | Time to Response (TTR) | Time to Response (TTR), defined as the time from the date of randomization to the date of first CR or PR. CR or PR is according to RECIST version 1.1. The TTR will be estimated using Kaplan-Meier method. A Kaplan-Meier curve, median TTR, hazard ratio with appropriate confidence intervals will be reported. |
From randomization to 36 month | |
Secondary | Clinical Benefit Response (CBR) | CBR is percentage of participants with best (confirmed) PR or CR or SD for at least 6 months. PR or CR or SD is according to RECIST version 1.1. The CBR will be reported by percentage with each arms and appropriate confidence intervals. |
From randomization to 36 month | |
Secondary | Adverse events (AEs) | AEs were graded according to the National Cancer Institute's Common Toxicity Criteria for Adverse Events (CTCAE) version 4.0.3. In general, AEs are graded according to the following: Grade 1 Mild AE Grade 2 Moderate AE Grade 3 Severe AE Grade 4 Life-threatening or disabling AE Grade 5 Death related to AE. The type, grade and frequency of AEs will be reported. |
From screening phase until AEs returns to Grade 0-1 or baseline | |
Secondary | Quality of Life (QoL) by FACT-B | QoL was assessed using Functional Assessment of Cancer Therapy for Breast Cancer (FACT-B). FACT-B is a 37-item questionnaire with 5 subscales assessing physical, social, emotional, and functional well-being, as well as a breast cancer specific subscale. FACT-B questionnaires were completed by patients on screening phase (baseline) and each 6 weeks after randomization. Mean change from baseline of FACT-B scores by each visit for each arms will be reported. |
From randomization to 36 month | |
Secondary | Quality of Life (QoL) by EQ-5D | QoL was assessed using EuroQoL 5-Dimensions (EQ-5D). EQ-5D is a standardized instrument developed by the EuroQol Group as a measure of health-related quality of life that can be used in a wide range of health conditions and treatments. EQ-5D questionnaires were completed by patients on screening phase (baseline) and each 6 weeks after randomization. Mean change from baseline of EQ-5D scores by each visit for each arms will be reported. |
