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

Mechanism of Disease

Up to 50% of patients with HR+/HER2- aBC or mBC have one or more PIK3CA, AKT1, or PTEN alterations1

After exposure to 1L ET ± CDK4/6i2-9

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 alterations10,11

NGS testing is recommended to identify drivers of disease progression and help inform personalized treatment plans12

National Comprehensive Cancer Network® (NCCN®) RECOMMENDATION12

At HR+/HER2- aBC or mBC diagnosis, NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Breast Cancer recommends:

Biomarker testing:

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

TEST patients for PIK3CA AKT1 PTEN alterations at aBC or mBC diagnosis13

Mechanism of Action

TRUQAP inhibits oncogenic signaling driven by PIK3CA, AKT1, or PTEN alterations9,14,15

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
