About this study

Official title: A Phase 3, Randomized, Double-Blind, Trial of Pamrevlumab (FG-3019) or Placebo in Combination With Systemic Corticosteroids in Ambulatory Subjects With Duchenne Muscular Dystrophy (DMD)

To evaluate the efficacy and safety of pamrevlumab versus placebo in combination with systemic corticosteroids administered every 2 weeks in ambulatory participants with Duchenne muscular dystrophy (DMD) (age 6 to <12 years).

Read the detailed description

This is a global, randomized, double-blind, trial of pamrevlumab or placebo in combination with systemic corticosteroids in participants with DMD, aged 6 to <12 years (ambulatory participants only). Approximately 70 participants will be randomized at a 1:1 ratio to Arm A (pamrevlumab + systemic deflazacort or equivalent potency of corticosteroids administered orally) or Arm B (placebo+ systemic deflazacort or equivalent potency of corticosteroids administered orally), respectively. Randomization will be stratified by exon 44 deletion for analysis. Stratification has no impact upon treatment assignment nor dosage.

Participants must be fully informed of the potential benefits of approved products and make an informed decision when participating in a clinical trial in which they could be randomized to placebo.

The main study has 3 study periods:

  • Screening period: Up to 4 weeks
  • Treatment period: 52 weeks
  • Safety Follow-up period/final assessment: A visit 28 days (+/- 3 Days) and a final safety follow-up phone call 60 days (+ 3 Days) after the last dose

Each participant will receive pamrevlumab or placebo at 35 mg/kg every 2 weeks for up to 52 weeks. Participants who complete 52 weeks of treatment may be eligible for an open-label extension (OLE), offering extended treatment with pamrevlumab.

Participants who discontinue study treatment for any reason should be encouraged to return to the investigative site to complete final safety and efficacy assessments.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in North Star Ambulatory Assessment (NSAA) Total Score at Week 52

    The NSAA consisted of 17 activities, each scored as 0 (activity could not be performed), 1 (modified method but achieved goal without physical assistance from another), or 2 (normal, achieved goal without assistance). The sum of these 17 scores was used to form a total score ranging from 0 (worst) to 34 (fully independent function). If fewer than 15 of the 17 activities were performed, the total score was considered missing. If 15 to 16 activities were performed, the total score was calculated by multiplying the sum of the scores in the x activities that were performed by 17/x. If an activity could not be performed due to disease progression/loss of ambulation, a score of 0 was assigned. Higher scores indicated better functioning. Least square (LS) mean and standard error (SE) were analyzed using a mixed model for repeated measure (MMRM).

    Measured: Baseline, Week 52

Secondary outcomes (4)
  1. Change From Baseline in 4-Stair Climb Velocity (4SCV) Assessment at Week 52

    The 4SCV (centimeters [cm]/second [sec]) was calculated as the ratio of the total height (cm) of stairs climbed divided by the number of seconds taken to complete the 4-stair climb.

    Measured: Baseline, Week 52

  2. Change From Baseline in the 10-Meter Walk/Run Test at Week 52

    The time (in sec) required for a participant to run or walk a distance of 10 meters as quickly as possible was calculated as velocity (meters/sec).

    Measured: Baseline, Week 52

  3. Change From Baseline in Time to Stand (TTSTAND) at Week 52

    The time (in sec) required for a participant to stand from supine position has been reported. A longer time taken reflected a worse outcome.

    Measured: Baseline, Week 52

  4. Time to Loss of Ambulation (LoA) From Baseline to Week 52

    Time (days) to LoA was defined as the number of days from randomization to the date of LoA, or all-cause death based on observed data, whichever occurred earlier during the on-study period. Median time (days) to LoA was calculated using Kaplan Meier Survival Estimates.

    Measured: Baseline to Week 52

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Pamrevlumab and Corticosteroids in people with Duchenne Muscular Dystrophy, run by Kyntra Bio at 52 sites in 11 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 25 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 26 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 52 sites in United States, China, Italy, Belgium, France and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Aug 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in North Star Ambulatory Assessment (NSAA) Total Score at Week 52 (time frame: Baseline, Week 52). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2024.
