In Summary

  • Regeneron Pharmaceuticals' Otarmeni, approved by US FDA, treats hearing loss from OTOF gene mutations.
  • OTOF gene mutations cause severe-to-profound hearing loss, affecting 2%-8% of inherited non-syndromic cases.
  • Otarmeni is a one-time gene therapy using dual AAV vectors to deliver a functional OTOF gene copy.

In Summary

The therapy, called Otarmeni, made by Regeneron Pharmaceuticals  was approved by United States Food and Drug Administration under National Priority Voucher Program

Key Highlights of the Approved Therapy

  • OTOF Gene Mutation: Therapy is designed to treat hearing loss caused by OTOF gene mutations.
    • OTOF Gene codes for a protein called otoferlin, needed by inner ear cells to translate vibrations into signals interpreted by brain. 
    • When people carry two defective copies of  this gene (one from each parent), it causes severe-to-profound hearing loss, accounting for 2%- 8% of inherited, non-syndromic cases.
  • Otarmeni: Is a one-time biologic-device combination product including a dual adeno-associated virus serotype 1 (AAV1) vector gene therapy. 
    • It delivers a functional copy of OTOF gene to inner hair cells to restore otoferlin production and auditory signalling.
    • Dual adeno-associated virus (AAV) therapy, involves the use of two different adeno-associated viruses (AAVs) to deliver therapeutic genes.

About Gene Therapy

  • Meaning: Refers to a collection of methods that allows correction of a gene defect. It involves insertion of genes into a person’s cells and tissues to treat a disease. 
    • A vector is a carrier used to deliver the therapeutic gene into target cells

Vector (in Gene Therapy)

A carrier, often a modified virus or bacterium, used in gene therapy to deliver a therapeutic gene into a patient's target cells. In Otarmeni, adeno-associated viruses (AAVs) act as vectors.

Gene Therapy

A therapeutic approach that involves correcting a gene defect by introducing new genes into a person's cells and tissues. It is used to treat diseases caused by genetic mutations, as exemplified by Otarmeni, which aims to replace a defective OTOF gene.

Adeno-associated virus (AAV) serotype 1 (AAV1) vector

A type of delivery vehicle (vector) used in gene therapy. AAVs are small viruses that can infect cells without causing disease and are modified to carry therapeutic genes into target cells. AAV1 is a specific subtype of AAV used in Otarmeni for its efficacy in delivering the OTOF gene to inner ear cells.
