Summary
Pfizer's innovative drug palbociclib (trade name: Ibrance) got China National Drug Administration (CNDA) approval on July 31, 2018. Palbociclib combined with an aromatase inhibitor can be used to treat hormone receptor-positive/human epidermal growth factor receptor 2-negative locally advanced breast cancer or metastatic breast cancer. This brings more treatment options for hormone receptor-positive/human epidermal growth factor receptor 2-negative locally advanced breast cancer. How to scientifically evaluate the efficacy, tolerability, and safety of palbociclib combined with an aromatase inhibitor and to establish a more suitable treatment strategy for Chinese patients is one of the questions that need to be answered in clinical practice. This multi-center parallel-group randomized controlled trial will address on this issue.
Description
Breast cancer is one of the most common cancers in women. Once advanced, it is usually not cured. Studies have shown that patients with advanced breast cancer have a median survival of 2-3 years. For inoperable locally advanced breast cancer, systemic therapy is the first choice of treatment. Systemic treatments of hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer mainly include endocrine monotherapy, multi-drug combination therapy and chemotherapy. The overall survival is similar between patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer receiving chemotherapy and those receiving endocrine therapy. But quality of life and progression-free survival of patients receiving endocrine therapy are superior to those of receiving chemotherapy. Therefore, both the National Comprehensive Cancer Network (NCCN) and the 2018 Chinese Expert Consensus on the Clinical Diagnosis and Treatment of Advanced Breast Carcinoma guidelines confirm that endocrine therapy is the preferred treatment for hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer.
Palbociclib is a cyclin-dependent kinase (CDK) 4/6 inhibitor that reduces the proliferation of estrogen receptor-positive breast cancer cells by blocking cells from the G1 phase to the S phase. Pfizer's innovative drug palbociclib (trade name: Ibrance) was approved by the China National Drug Administration on July 31, 2018 for the treatment of hormone receptor-positive/human epidermal growth factor receptor 2-negative locally advanced breast cancer or metastatic breast cancer. In addition, aromatase inhibitors such as letrozole (trade name: Femara ) can prolong the progression-free survival in the first-line therapy for advanced breast cancer to 10-13 months. Palbociclib combined with letrozole has been shown to exhibit stronger inhibitory effects on phosphorylation of retinoblastoma gene (Rt), downstream signaling and tumor growth than monotherapy. Since 2015, palbociclib combined with letrozole has been recommended by the NCCN guideline as one treatment option for advanced breast cancer. However, since palbociclib has been approved for market entry in China for only 1 year, little is reported in China regarding large-sample clinical trials regarding the efficacy, tolerability, and safety of palbociclib combined with an aromatase inhibitor in hormone receptor-positive/human epidermal growth factor receptor 2-negative locally advanced breast cancer.
