Coverage Summary

This policy covers Wainua (eplontersen) with prior authorization/medical necessity for treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis (hATTR) in adults. Prescriber requirement: must be prescribed by or in consultation with a neurologist. Diagnostic requirements: documented diagnosis of hATTR with polyneuropathy and documentation of a pathogenic TTR mutation (e.g., V30M). Severity requirements: baseline disease severity must meet one of the following thresholds — PND score ≤ IIIb, FAP Stage 1 or 2, or NIS score ≥ 10 and ≤ 130. Combination therapy exclusions: not to be used in combination with specified oligonucleotide agents (e.g., Onpattro/patisiran, Amvuttra/vutrisiran, Tegsedi/inotersen) or transthyretin stabilizers (e.g., Vyndaqel/Vyndamax/tafamidis, Attruby/acoramidis). Authorization duration: 12 months.

Initial Therapy Criteria

Initial Authorization

Wainua will be approved based on all of the following criteria:

ALL of the following

Both of the following
- Diagnosis of hATTR amyloidosis with polyneuropathy
- Documentation that the patient has a pathogenic TTR mutation (e.g., V30M)
Prescribed by or in consultation with a neurologist
Documentation of one of the following
- Patient has a baseline polyneuropathy disability (PND) score ≤ IIIbPND score ≤ IIIb
- Patient has a baseline FAP Stage 1 or 2FAP Stage 1 or 2
- Patient has a baseline neuropathy impairment (NIS) score ≥ 10 and ≤ 130NIS score between 10 and 130 inclusive
Patient has not had a liver transplant
Presence of clinical signs and symptoms of the disease (e.g., peripheral sensorimotor polyneuropathy, autonomic neuropathy, motor disability, etc.)
Not receiving Wainua in combination with either of the following
- Not receiving oligonucleotide agents (e.g., Onpattro [patisiran], Amvuttra [vutrisiran], Tegsedi [inotersen])
- Not receiving a transthyretin stabilizer (e.g., Vyndaqel/Vyndamax [tafamidis], Attruby [acoramidis])

Continuation / Reauthorization Criteria

Reauthorization

Wainua will be approved for reauthorization when BOTH of the following are met:

ALL of the following

Documentation that the patient has experienced a positive clinical response to Wainua therapy (e.g., improved neurologic impairment, motor function, quality of life, slowing of disease progression, etc.)
Clinical measures should be documented in chart / prior auth submission
Not receiving Wainua in combination with either of the following
- Not receiving oligonucleotide agents (e.g., Onpattro [patisiran], Amvuttra [vutrisiran], Tegsedi [inotersen])
- Not receiving a transthyretin stabilizer (e.g., Vyndaqel/Vyndamax [tafamidis], Attruby [acoramidis])

Authorization will be issued for 12 months.

Provider Actions & Requirements

Prior Authorization

Prior authorization required for Wainua

Prior authorization / medical necessity is required for Wainua (eplontersen). Initial approval requires documentation of: diagnosis of hATTR amyloidosis with polyneuropathy; a pathogenic TTR mutation (e.g., V30M); prescriber is a neurologist or in consultation with one; baseline disease severity meeting one of the specified thresholds (PND ≤ IIIb, FAP Stage 1 or 2, or NIS score between 10 and 130); no prior liver transplant; presence of clinical signs/symptoms of disease; and not receiving Wainua in combination with disallowed agents.

Documentation Required

Documentation of mutation and baseline severity required

Submit documentation of the pathogenic TTR mutation (example: V30M) and the patient’s baseline disease severity — e.g., PND score, FAP stage, or NIS score — with the prior authorization request.

Documentation Required

Reauthorization clinical response documentation

For reauthorization, provide documentation that the patient has experienced a positive clinical response to Wainua (examples include improved neurologic impairment, improved motor function, improved quality of life, or slowing of disease progression).

Billing Rule

Authorization duration

Authorizations for Wainua are issued for 12 months.

Background

Wainua (eplontersen) is a transthyretin-directed antisense oligonucleotide indicated for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis (hATTR) in adults. This policy documents that prior authorization/medical necessity is required under UnitedHealthcare Pharmacy Clinical Pharmacy Programs (Program 2025 P 2326-2).

Definitions: hATTR — hereditary transthyretin-mediated amyloidosis; PND — polyneuropathy disability score; FAP Stage — familial amyloid polyneuropathy stage; NIS — Neuropathy Impairment Score.
