In combination with fulvestrant for patients with HR+/HER2− aBC or mBC with PIK3CA, AKT1, or PTEN alterations following progression on or after ET ± CDK4/6i1

Mechanism of Disease

PIK3CA, AKT1, and PTEN alterations are key drivers of disease progression2-4

Up to 50% of patients with HR+/HER2- advanced or metastatic breast cancer have one or more of these actionable alterations4

After exposure to 1L ET ± CDK4/6i5-12

Reducing Discontinuation Rates Graph

Better treatment options have been urgently needed to improve outcomes while reducing discontinuation rates due to adverse reactions for patients with PIK3CA, AKT1, or PTEN alterations

Alterations in the PI3K/AKT/PTEN pathway are associated with poor prognosis, most notably for patients with PIK3CA mutations13,14

Biomarker testing: 

  • Biopsy of at least the first recurrence of disease (consider re-biopsy if progression occurs) 
  • Multigene panel testing (MGPT) (somatic and germline) to identify candidates for targeted therapies

TRUQAP Mechanism of Action

TRUQAP inhibits oncogenic signaling driven by PIK3CA, AKT1, or PTEN alterations12,17,18

TRUQAP + fulvestrant is the first and only combination to leverage the dual power of AKT inhibition + ER downregulation to reduce tumor growth driven by the PI3K/AKT/PTEN and ER pathways

Mechanisms of resistance and alterations in the PI3K/AKT/PTEN pathway in HR+/HER2– aBC or mBC

During first-line treatment with endocrine therapy plus a CDK4/6 inhibitor, mechanisms of resistance develop to allow cancer cells to escape treatment effects.

The most common treatment resistance pathway responsible for driving disease progression is the PI3K/AKT/PTEN pathway.

Mechanisms of resistance, like PIK3CA- and AKT1-activating mutations and PTEN loss of function alterations, can cause amplified signaling, resulting in uncontrolled tumor growth.

These alterations are present in up to 50% of patients with breast cancer, and, most notably, PIK3CA-activating mutations are associated with poor prognosis.

The estrogen receptor pathway can also fuel tumor growth independent of the PI3K/AKT/PTEN pathway, making it critical to use treatment strategies that target both pathways.

How TRUQAP and fulvestrant work

TRUQAP inhibits amplified signaling from PIK3CA- and AKT1-activating mutations, and PTEN loss of function alterations, by targeting AKT, the master switch of the pathway. This mechanism of action restricts the flow of amplified signals before they can have further downstream effects that drive tumor growth.

Fulvestrant binds to and causes downregulation of estrogen receptors to reduce estrogen-driven tumor growth. TRUQAP plus fulvestrant leverages the dual power of AKT inhibition and ER downregulation to reduce tumor growth with the goal of extending time on endocrine therapy. Test for PIK3CA, AKT1, and PTEN alterations. Treat with TRUQAP plus fulvestrant in second line.

Select Safety Information About TRUQAP® (capivasertib) tablets

TRUQAP is contraindicated in patients with severe hypersensitivity to TRUQAP or any of its components.

Serious adverse reactions include hyperglycemia, including diabetic ketoacidosis and fatal outcomes; diarrhea; and cutaneous adverse reactions. Monitor fasting glucose and hemoglobin A1C levels regularly. May cause fetal harm when administered to a pregnant woman. Among the 355 patients who received TRUQAP in CAPItello-291, the most common (≥20%) adverse reactions, including laboratory abnormalities, were diarrhea (72%), cutaneous adverse reactions (58%), increased random glucose (57%), decreased lymphocytes (47%), decreased hemoglobin (45%), increased fasting glucose (37%), nausea and fatigue (35% each), decreased leukocytes (32%), increased triglycerides (27%), decreased neutrophils (23%), increased creatinine (22%), vomiting (21%), and stomatitis (20%).

Indication and Usage

TRUQAP in combination with fulvestrant is indicated 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 alteration as detected by an FDA-authorized 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.
