A Study to Assess Safety/Tolerability, pk, Effects on Histology, Clinical Parameters of Givinostat in Children With DMD
Italy20 participantsStarted 2013-04
Plain-language summary
The primary objective of Parts 1 and 2 of the study were to establish the histologic effects of givinostat administered chronically at the selected daily dose.
The secondary objectives of Parts 1 and 2 of the study were as follows:
* To establish the effects of givinostat administered chronically at the selected daily dose on functional parameters, such as the 6-Minute Walk Test (6MWT), North Star Ambulatory Assessment (NSAA), and performance of upper limb (PUL)
* To establish the safety and tolerability of givinostat administered chronically at the selected daily dose in children with Duchenne muscular dystrophy (DMD)
* To explore the effects of givinostat administered chronically at the selected daily dose on parameters such as magnetic resonance imaging (MRI) and biomarkers
* To explore the acceptability/palatability of the oral suspension
* To explore whether the effects of givinostat on disease progression may be related to the type of DMD mutation.
The primary objective of the Extension of the study was to evaluate the safety and tolerability of long-term administration of givinostat administered chronically at the selected daily dose in children with DMD.
The secondary objectives of the Extensions were:
* To establish the effects of givinostat administered chronically at the selected daily dose on muscular functional parameters, such as the 6MWT, NSAA, and PUL (Extensions 1, 2, and 3)
* To explore the effects of givinostat administered chronically at the selected daily dose on parameters such as MRI (Extension 1)
* To collect information related to 2 biomarkers, latent Transforming growth factor β (TGFβ) binding protein 4 (LTBP4) and osteopontin genotype (at the beginning of Extension 2 only)
* To collect information related to time to wheelchair and how much time the children spend in wheelchair (Extension 3 - only for the children who were not able to complete the 6MWT)

Inclusion criteria
✓. Male children aged 7 to \<11 years with an immunohistochemical and molecular diagnosis of DMD.
✓. A parent/guardian and child can comply with all study evaluations/procedures and return for all study activities.
✓. Able to complete the 2 screening 6MWTs with a minimal distance of at least 250 m each. In addition, the results of these tests must be within ±30 m of each other.
✓. On a stable dose of systemic corticosteroids for at least 6 months.
✓. At least 6 months worth of data on the 6MWT (this will be the "historical" 6MWT). From the moment of the historical 6MWT assessment(s), the child must not have received any compound that could potentially affect the 6MWT, with the exception of the stable steroid treatment.
✓. Parent/guardian has signed the informed consent form and child has assented to be in the study (if applicable).
Exclusion criteria
✕. Initiation of systemic corticosteroid therapy within 6 months prior to the start of study drug or change in systemic corticosteroid therapy (e.g., initiation, change in type of drug, dose modification not related to body weight change, schedule modification, interruption, discontinuation, or re initiation) within 6 months prior to the start of study drug.
What they're measuring
1
Change From Baseline to Part 2 in the Value of Muscle Fiber Area (MFA) % Comparing the Histology Biopsies Before and After 12 Months of Treatment With Givinostat.
✕. Use of any pharmacologic treatment, other than corticosteroids, that might have an effect on muscle strength since the time of the historical 6MWT and in any case within 3 months prior to the start of study treatment (e.g., growth hormone). Vitamin D, calcium, and integrators will be allowed.
✕. Surgery that might have an effect on muscle strength or function within 3 months before study entry or planned surgery at any time during the study.
✕. Exposure to another investigational drug since the time of the historical 6MWT and in any case within 3 months prior to the start of study treatment.
✕. History of participation in gene therapy, cell-based therapy or oligonucleotide therapy.
✕. Presence of other clinically significant disease that in the opinion of the investigator places the child in unacceptable risk for an adverse outcome or that could affect study results.
✕. Symptomatic cardiomyopathy or heart failure. If child has a left ventricular ejection fraction \<45% at screening, the investigator should discuss inclusion of child in the study with the medical monitor.
