STUDY DESIGN
The NEURO-TTRansform trial studied the efficacy
and safety of WAINUA in adults with hATTR-PN1,2
A phase 3, randomized, open-label, externally controlled, multicenter study1-3
The external placebo control from NEURO-TTR was appropriate because of similar eligibility criteria and endpoints1,3,4
*Patients included in NEURO-TTRansform were 18 to 82 years of age, and had a confirmed diagnosis of hATTR-PN as defined by all of the following: Stage 1 (ambulatory without assistance) or Stage 2 (ambulatory with assistance) familial amyloid polyneuropathy or Coutinho stage; documented mutation of the TTR gene; and signs and symptoms consistent with hATTR-PN, including NIS ≥10 and ≤130. Patients must have discontinued active treatment with any other approved drug for hATTR 2 weeks prior to study.2,3
†The inotersen reference group was intended to confirm sufficiently comparable disease progression and treatment response patterns between NEURO-TTR and NEURO-TTRansform trials.3
‡All endpoints were compared with the placebo arm of the earlier NEURO-TTR trial (NCT01737398).1,2,4
§The final analysis endpoints were distributed over 2 visits (Week 65 and Week 66), as prespecified in the protocol.3

IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
- Reduced Serum Vitamin A Levels and Recommended Supplementation WAINUA leads to a decrease in serum vitamin A levels. Supplement with recommended daily allowance of vitamin A. Refer patient to an ophthalmologist if ocular symptoms suggestive of vitamin A deficiency occur.
ADVERSE REACTIONS
Most common adverse reactions (≥9% in WAINUA-treated patients) were vitamin A decreased (15%) and vomiting (9%).
INDICATION
WAINUA injection, for subcutaneous use, 45 mg is indicated for the treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis
in adults.
