The Expanded Access Use of Viltolarsen in Duchenne Muscular Dystrophy With Confirmed Exon 53 Amenable Mutation

August 14, 2020 updated by: NS Pharma, Inc.

The Expanded Access Use of Viltolarsen for the Treatment of Duchenne Muscular Dystrophy (DMD) Amenable to Exon 53 Skipping

This is an open label expanded access program for boys, 3 to 12 years old, for the treatment of Duchenne muscular dystrophy (DMD) with confirmed mutation(s) in the dystrophin gene that is amenable to skipping of exon 53.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Approved for marketing

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This expanded access program is designed to provide access to viltolarsen in patients with DMD with confirmed mutation(s) in the dystrophin gene amenable to skipping of exon 53, who in the opinion and clinical judgement of the treating physician, would benefit from treatment with viltolarsen.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Expanded Access

Expanded Access Type

Expanded Access Type

Describes the category of expanded access under U.S. Food and Drug Administration (FDA) regulations. There are three types of expanded access:
  • Individual Patients: Allows a single patient, with a serious disease or condition who cannot participate in a clinical trial, access to a drug or biological product that has not been approved by the FDA. This category also includes access in an emergency situation.
  • Intermediate-size Population: Allows more than one patient (but generally fewer patients than through a Treatment IND/Protocol) access to a drug or biological product that has not been approved by the FDA. This type of expanded access is used when multiple patients with the same disease or condition seek access to a specific drug or biological product that has not been approved by the FDA.
  • Treatment IND/Protocol: Allows a large, widespread population access to a drug or biological product that has not been approved by the FDA. This type of expanded access can only be provided if the product is already being developed for marketing for the same use as the expanded access use.
  • Individual Patients

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Male ≥ 3 and ≤ 12 years of age
  • Clinical signs compatible with DMD
  • Confirmed DMD mutation(s) in the dystrophin gene that is amenable to skipping of exon 53 to restore the dystrophin messenger ribonucleic acid (mRNA) reading frame
  • Able to walk independently without assistive device
  • Not able to participate in a Phase 3 trial

Exclusion Criteria:

  • Chronic systemic fungal or viral infections
  • An acute illness within 4 weeks prior to the first dose of viltolarsen
  • Symptomatic cardiomyopathy
  • Patient has a previous or ongoing medical condition, medical history, physical findings, or laboratory abnormality that could affect participant safety in the opinion of the treating physician
  • Surgery within the 3 months prior to the first anticipated administration of viltolarsen and in the opinion of the treating physician would impact weekly treatment schedule
  • Positive test results for hepatitis B antigen, hepatitis C antibody, or human immunodeficiency virus (HIV) antibody at screening
  • Currently taking any other investigational drug or has taken any other investigational drug within 3 months prior to the first dose of viltolarsen
  • Previously enrollment in any viltolarsen study.
  • Currently taking any other exon skipping agent or has taken any other exon skipping agent within 2 weeks prior to the first dose of viltolarsen (would need to be discontinued in order to be eligible)
  • Any gene therapy for DMD
  • Inadequate renal function as defined by a serum cystatin C > 1.5 x upper limit of normal (ULN). If the value is > 1.5 x ULN then the measurement can be repeated once. If repeat measurement is still > 1.5 x ULN then the patient should be excluded.
