Study Overview

Status

Status

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

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

The main purpose of this study is to determine the effect of MNK-1411 on motor function in participants with Duchenne Muscular Dystrophy (DMD). Information is collected only from caretakers who are fluent in English, using the Pediatric Outcomes Data Collection Instrument (PODCI).

The PODCI is a validated 86-question instrument completed by the parent or legal guardian of children 2 to 10 years of age to assess a variety of health outcome measures (Uzark et al, 2012). This study will only collect information for the PODCI domains of sports and physical functioning and transfer/basic mobility.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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

4 years to 8 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  1. Participants must have a documented diagnosis of Duchenne Muscular Dystrophy (DMD) confirmed by complete dystrophin deficiency (by immunofluorescence and/or immunoblot), or identifiable mutation in the DMD gene where reading frame can be predicated as "out of frame," or complete dystrophin gene sequencing consistent with DMD; AND in the opinion of the Investigator, a typical clinical profile consistent with DMD.
  2. Participants taking approved treatments for DMD (by a Health Authority) that target dystrophin gene mutations (e.g., eteplirsen or ataluren) may be enrolled in the study if they have been on a stable dose for 30 days prior to the first dose of study drug, and plan to remain on that dose throughout the study.

Exclusion Criteria:

  1. Participant has had previous systemic treatment with corticosteroids within 2 months prior to the Screening Visit. Exception: In subjects who were down-titrated to a physiological dose of corticosteroids (ie, 3mg/m2 of prednisone or deflazacort) a maximum of 1 month of no greater than a physiological dose followed by 1 month completely off corticosteroids prior to the Screening Visit will be acceptable for study entry. Transient previous use of corticosteroids will be evaluated on a case-by-case basis by the sponsor or designee. The use of topical or intra-articular corticosteroids is permitted during the study
  2. Participant is unable to complete the 10 meter Walk/Run test at the Screening and/or Baseline Visit.
  3. Participant has Type 1 or Type 2 diabetes mellitus.
  4. Participant has a history of chronic active hepatitis including acute or chronic hepatitis B, or acute or chronic hepatitis C.
  5. Participant has a history of tuberculosis (TB) infection, any signs/symptoms of TB, or any close contact with an individual with an active TB infection.
  6. Participant has known immune compromised status (not related to disease/condition under study), including but not limited to, individuals who have undergone organ transplantation or who are known to be positive for the human immunodeficiency virus.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to Complete 10 Meter Walk/Run[
Time Frame: Baseline, Week 24
10 Meter Walk/Run is a motor function test to measure the functional capability in patients with DMD.
Baseline, Week 24

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
North Star Ambulatory Assessment (NSAA) Score
Time Frame: Baseline, Week 24
The NSAA is comprised of 17 items, each of which is graded using the standard scorecard. Each assessment is rated as 0 - unable to achieve independently, 1 - modified method but achieves goal independent of physical assistance from another, or 2 - normal with no obvious modification of activity. The subscale scores are summed for a total score ranging from 0 to 34. The higher the total score, the better the outcome.
Baseline, Week 24
Time to Climb 4 Standardized Stairs
Time Frame: Baseline, Week 24
Time to Climb 4 Standardized Stairs is a motor performance test
Baseline, Week 24
Time to Stand From a Supine Position
Time Frame: Baseline, Week 24
Time to stand from a supine position is a motor function test to measure the functional capability in subjects with DMD.

Time Frame: Baseline
Quantitative muscle testing measured strength-knee flexion and extension measured in Newtons, using a dynamometer
