Expanded Access Protocol for Boys With Duchenne Muscular Dystrophy

January 16, 2026 updated by: Santhera Pharmaceuticals

An Open-Label, Expanded Access Protocol for Boys With Duchenne Muscular Dystrophy Who Have Completed the Long-Term Extension (VBP15-LTE) or VBP15-004 or VBP15-006 Studies

The intent of this protocol is to provide continued access to vamorolone for subjects in the United States and Canada who have completed the VBP15-LTE, VBP15- 004, or VBP15-006 protocols (and are thereby ineligible to enroll in another trial of vamorolone therapy), during the time a new drug application for vamorolone is under preparation and review.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Available

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

Vamorolone will be shipped to the subject's family by the study site. The patient will receive standard of care treatment and procedures for management of DMD. Treating Physicians participating in the expanded access program are required to collect and document any physician, patient, or caregiver reported safety events and report to the Sponsor. The subject's dose of vamorolone may be increased or decreased within a range of 2.0 to 6.0 mg/kg/day (only doses of 2 mg/kg, 4 mg/kg and 6 mg/kg are allowed), given once daily. Administration of vamorolone (taken with an 8 ounce (240 ml) glass of full fat milk, or equivalent high-fat food portion) will be unchanged from the VBP15-LTE, VBP15-004, or VBP15-006 studies. In the absence of safety concerns, and while this Expanded Access protocol is active, vamorolone may be provided indefinitely or until approval, provided that the Treating Physician and family agrees that continued administration of vamorolone is in the best interest of the child.

VBP15-EAP (under IND 118942) has been closed as vamaorolone is approved for marketing in the US VBP15-EAP CANADA has been approved by Health Canada on 11 July 2019 and is currently on-going,but not recruiting

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.
  • Intermediate-size Population

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.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

  • Subject and parent/guardian are willing and able to comply with recommended study drug administration plan, and standard of care follow-up and monitoring as recommended by their Treating Physician
