Drug Combination Slows Growth of Most Common Type of Advanced Breast Cancer
The combination of taselisib and fulvestrant has shown to slow the growth of cancer in post-menopausal women with estrogen receptor (ER)-positive, human epidermal growth factor receptor-2 (HER2) negative, PIK3CA-mutant, inoperable, locally advanced or metastatic breast cancer. Researchers from Memorial Sloan Kettering Cancer Center (MSK) presented this data, from the SANDPIPER trial, in a press conference at the annual meeting of the American Society of Clinical Oncology. This combination of a mutant-selective PI3K inhibitor and a selective estrogen receptor degrader halted the growth of advanced breast cancer for two months longer than hormone therapy alone and decreased the chance of cancer worsening by 30 percent.
