Therapeutic Response Statement (Sensitivity)
This therapeutic response statement supports the relationship that AKT1 amplification, HER2-negative, PR positive status confers therapeutic sensitivity to Capivasertib, Fulvestrant in patients with Invasive Breast Carcinoma.
The U.S. Food and Drug Administration granted approval to capivasertib in combination with fulvestrant for the treatment of adult patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer with one or more PIK3CA/AKT1/PTEN-alterations as detected by an FDA-approved test following progression on at least one endocrine-based regimen in the metastatic setting or recurrence on or within 12 months of completing adjuvant therapy. The efficacy of capivasertib in combination with fulvestrant was evaluated in CAPItello-291 (NCT04305496), which described biomarker eligibility as PIK3CA/AKT1 activating mutations or PTEN loss of function alterations.
This statement is based on a regulatory approval from the Food and Drug Administration:
TRUQAP is a kinase inhibitor indicated, in combination with fulvestrant for the treatment of adult patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer with one or more PIK3CA/AKT1/PTEN-alterations as detected by an FDA-approved test following progression on at least one endocrine-based regimen in the metastatic setting or recurrence on or within 12 months of completing adjuvant therapy.
