WE ARE BREAKING BARRIERS

AveXis is relentlessly focused on bringing gene therapy out of the lab and into the clinical setting.

We are a clinical-stage gene therapy company, dedicated to developing and commercializing novel treatments for patients suffering from rare and life-threatening neurological genetic diseases. Our initial proprietary gene therapy candidate, AVXS-101, is currently in an ongoing Phase 1 clinical trial for the treatment of SMA Type 1.

MOMENTUM IN GENE THERAPY: AVXS-101

Our proprietary gene therapy candidate, AVXS-101, is in human clinical trials for the treatment of spinal muscular atrophy (SMA) Type 1. SMA is a severe neuromuscular disease caused by a genetic defect in the SMN1 (survival motor neuron 1) gene, leading to the loss of motor neurons and resulting in progressive muscle weakness and paralysis.

The AVXS-101 Design

We’ve developed AVXS-101 to possess four key elements of an optimal gene therapy approach to SMA.

  • 01

    Recombinant AAV9 Capsid Shell is a non-replicating adeno-associated virus capsid used to deliver a functional copy of the human SMN gene across the blood-brain barrier to cells without modifying the patient’s existing DNA

  • 02

    Human SMN Transgene is a stable, functioning SMN gene that is introduced into the cell’s nucleus

  • 03

    scAAV ITR
    (Self-complementary DNA Technology)
    is a human SMN transgene introduced as a self-complementary double- stranded molecule. The inclusion of this technology enables rapid onset of effect

  • 04

    Continuous Promoter activates the transgene and is designed to allow for continuous and sustained SMN expression

GOING AFTER THE #1 GENETIC CAUSE OF INFANT MORTALITY

Our initial focus is on helping patients and families affected by spinal muscular atrophy (SMA) Type 1—a life-threatening neuromuscular disease that currently has no approved treatment—with our clinical-stage, proprietary gene therapy candidate, AVXS-101.
