Provider must document disease progression while on adjuvant endocrine therapy or disease recurrence within 12 months after completing adjuvant endocrine therapy.

Documentation Required

Document ovarian suppression or surgical status for pre/perimenopausal females or males

For pre/perimenopausal females or males, document receipt of a gonadotropin‑releasing hormone (GnRH) agonist or surgical bilateral oophorectomy/ovarian irradiation (female) or orchiectomy (male).

GnRH agonist examples: leuprolide acetate, triptorelin, goserelin
Surgical options: bilateral oophorectomy, ovarian irradiation (female); orchiectomy (male)

Denial Risk

Not covered for other uses

Itovebi is considered experimental, investigational or unproven for any use not listed in the Recommended Authorization Criteria; coverage is not recommended for other indications and claims for such uses may be denied.

Background and Evidence

Background: Itovebi is a kinase inhibitor indicated in combination with Ibrance (palbociclib) and fulvestrant for treatment of hormone receptor–positive, HER2-negative, PIK3CA‑mutated, endocrine‑resistant locally advanced or metastatic breast cancer in adults, per FDA labeling. The labeling recommends evaluating fasting plasma glucose/blood glucose and hemoglobin A1c (HbA1c) before initiating therapy, optimizing blood glucose prior to initiation, and monitoring glucose at regular intervals during treatment. NCCN guidance endorses the combination (category 1) for patients with disease progression on adjuvant endocrine therapy or relapse within 12 months of adjuvant endocrine therapy completion.
