For continuation requests, provide chart notes or medical record documentation supporting positive clinical response. These submission requirements are referenced in the criteria for initial and continuation authorization.

Initial requests: PIK3CA mutation test results
Continuation requests: chart notes/medical records showing positive clinical response

Billing Rule

Quantity limits enforced

Quantity limits are enforced for Vijoice product forms per the policy.

Tablets - 56 tablets per 28 days
Oral granules - 28 packets per 28 days

Clinical Evidence

27%Radiologic response rate at week 24 (≥20% reduction in sum of target lesion volume)

60%Duration of response ≥12 months among responders

14%Mean reduction in sum of target lesion volume among imaged patients

Key evidence sources supporting the approval and use of Vijoice for PROS include the EPIK-P1 retrospective chart review (compassionate use program) which reported a 27% radiological response rate at week 24 and a 60% duration of response ≥12 months, with reductions in target lesion volume and generally manageable safety findings, and the FDA approval documentation (Vijoice package insert, April 2024). Together these data supported the FDA approval of Vijoice for patients with severe PROS requiring systemic therapy.

Background & Definitions

PROS (PIK3CA-Related Overgrowth Spectrum) is a group of rare genetic disorders caused by activating PIK3CA mutations that lead to asymmetric regional overgrowth of various tissues (e.g., fat, muscle, bone, nerve, brain, and blood vessels) affecting areas such as the brain, limbs, trunk, and face. Vijoice (alpelisib) is a targeted PIK3CA inhibitor indicated for patients aged 2 years and older with severe manifestations of PROS who require systemic therapy; it inhibits the PIK3CA-driven signaling pathway implicated in these overgrowth disorders. Traditional management of PROS is primarily supportive and surgical (including surgery, sclerotherapy, and psychological and nutritional support), and some patients have received mTOR inhibitors (e.g., sirolimus) with moderate and inconsistent effects; targeted PIK3CA inhibition with alpelisib offers an approved therapeutic option for severe disease. Quantity limits are specified for dispensing: 56 tablets per 28 days for tablets and 28 packets per 28 days for oral granules.
