A Phase 2 Open-label (Core Phase Plus Extension Phase) With 2 Cohorts Study to Assess the Pharmacokinetics and Safety of Givinostat in DMD Patients Ages From at Least 2 Years to Less Than 6 Years Old

This is a Phase 2 Open-label (Core Phase Plus Extension Phase) With 2 Cohorts Study to Assess the Pharmacokinetics and Safety of Givinostat in younger DMD Patients.

* Planned screening duration: approximately 4 weeks * Planned Core Treatment duration: approximately 48 weeks * Planned Extension Treatment duration: approximately 96 weeks * Planned Follow Up duration: approximately 4 weeks (± 7 days) * Total duration of study participation: up to 151 weeks (ie, 37-38 months)

Bevonási feltételek: Male children aged ≥2 to <6 years at screening (subjects ≥6 years of age at screening will not be enrolled into the study); Written consent provided by parent/legal guardian and subject written assent, if applicable (according to local regulation); A genetic diagnosis of DMD; Corticosteroid treatment considerations:; For subject receiving a stable dose or oral systemic corticosteroids:; No significant change in dose or dosing regimen (except for adjustments due to body weight change) for a minimum of 3 months immediately prior to the start of the study drug or; For subjects without current corticosteroid treatment:; Must not start corticosteroids in the Core Phase of the study (ie, first 48 weeks); Must have participated in the Core Phase study (48 weeks) and have attended the End of Treatment Visit; Give informed consent and /or assent in writing signed by the parent/legal guardian and/or subject (according to local regulation); In stable oral systemic corticosteroids treatment with no significant change in dose or dosing regimen (except for adjustments due to body weight change). For subjects without corticosteroids during the Core Phase, the treatment can be started based on the Investigator's clinical medical judgement.

Kizáró feltételek: Exposure to another investigational drug within 3 months prior to the start of the study drug; Exposure to any dystrophin restoration product (eg, Ataluren, Exon skipping) within 6 months prior to the start of study drug; Received any gene therapy (eg, AAV Micro-dystrophin delivery) within 12 months prior to start of study drug; Have had surgery that might have an effect on muscle strength or function within 3 months prior to start of the study drug or planned surgery at any time during the study; The presence of other clinically significant disease, which, in the Investigator's opinion, could adversely affect subject's safety, making it unlikely to complete the study or to be compliant with study-specific requirements that could impair the assessment of study results; Diagnosis of other uncontrolled neurological diseases or presence of relevant uncontrolled somatic disorders that are not related to DMD, based on Investigator clinical medical judgement; Positive test for hepatitis B surface antigen, hepatitis C antibody, or human immunodeficiency virus at screening; Psychiatric illness or social situations rendering the potential subject unable to understand and comply with the muscle function tests and/or with the study protocol procedures, based on the Investigator's clinical medical judgement; Hypersensitivity to any component of study drug; Have presence of other clinically significant disease, which, in the Investigator's opinion, could adversely affect the safety of the subject, making it unlikely that the course of treatment or follow-up would be completed, or could impair the assessment of study results; Evidence of psychiatric illness or social situations rendering the potential subject unable to understand and comply with the muscle function tests and/or with the study protocol procedures, based on the Investigator's clinical medical judgement; Use of any pharmacologic treatment, other than corticosteroids, that might have had an effect on muscle strength or function within 3 months prior to the start of the study drug (eg, growth hormone). Note: Vitamin D, calcium, and any other supplements will be allowed; Platelet count, white blood cells, and/or haemoglobin counts < lower limit of normal (LLN) at screening (Note: for abnormal screening laboratory test results [<LLN], the platelet count, white blood cell, and haemoglobin will be repeated once; if the repeat test result is still <LLN, the subject will be excluded); Current or history of liver disease or impairment, including but not limited to a baseline elevated total bilirubin (ie, >1.5 × upper limit of normal [ULN]), unless secondary to Gilbert disease or pattern consistent with Gilbert disease; Inadequate renal function, as defined by serum Cystatin C result >2 × ULN (Note: if the value is >2 × ULN, the serum Cystatin C will be repeated once; if the repeated test result is still >2 × ULN, the subject will be excluded); Fasting triglycerides >300 mg/dL (3.42 mmol/L) at screening (Note: if the value is >300 mg/dL, the triglycerides will be repeated once; if the repeated test result is still >300 mg/dL in fasting, the subject should be excluded); Baseline corrected QT interval using Fridericia's formula (QTcF) >450 msec (as the mean of 3 consecutive readings taken 5 minutes apart) or history of additional risk factors for torsades de pointes (ie, heart failure, hypokalaemia, or family history of long QT syndrome); Platelet count, white blood cells, and/or haemoglobin <LLN at EOT/V12 (Note: for abnormal laboratory test results [<LLN], the platelet count, white blood cell, and haemoglobin will be repeated once; if the repeat test result is still <LLN, the subject will be excluded); Current liver disease or impairment, including but not limited to an elevated total bilirubin (ie, >1.5 × ULN), unless secondary to Gilbert disease or pattern consistent with Gilbert disease; Inadequate renal function, as defined by serum Cystatin C result >2 × ULN (Note: if the value is >2 × ULN, the serum Cystatin C will be repeated once; if the repeated test result is still >2 × ULN, the subject will be excluded); Fasting triglycerides >300 mg/dL (3.42 mmol/L; Note: if the value is >300 mg/dL, the triglycerides will be repeated once; if the repeated test result is still >300 mg/dL in fasting condition, the subject should be excluded); Sorbitol intolerance or malabsorption or have the hereditary form of fructose intolerance; Body weight <10 kg at screening.
