The primary objective of the study is to evaluate vigabatrin pharmacokinetics (PK) in neonates receiving vigabatrin for infantile spasms (IS); and to determine the safety of vigabatrin.

Condition Intervention Phase
Infantile Spasms Drug: Vigabatrin Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: An Open-Label, Single and Multiple Oral Dose Pharmacokinetic Study of Vigabatrin in Infants With Infantile Spasms

Further study details as provided by Lundbeck LLC:

Primary Outcome Measures:
  • Non-compartmental pharmacokinetic profile of vigabatrin after oral administrations in infants(>=1 and <6 months of age) [ Time Frame: 24 hrs post dose on Day 1 and 12 hrs post dose on Day 5 ]
    Serial blood for plasma generation will be collected on Days 1 and 5 and vigabatrin concenrations determined to the determine the pharmacokinetic profile of vigabatrin

Secondary Outcome Measures:
  • To determine the safety of vigabatrin following oral dose administrations in infants (>=1 and <6 months of age) [ Time Frame: Safety collected throughout the 5-day study ]
    Safety and tolerability parameters such as adverse events, clinical safety laboratory tests and vital signs will be summarised using descriptive statistics

Enrollment: 0
Study Start Date: June 2012
Estimated Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vigabatrin Drug: Vigabatrin
Oral vigabatrin as a single 25 mg/kg dose on Days 1 and 5, 25 mg/kg twice a day (50 mg/kg daily dose, orally) on Days 2-4
Other Name: Sabril®


Ages Eligible for Study:   1 Month to 6 Months   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • The patient's parent or legally authorized representative is able to read and understand the Patient Information Sheet and Informed Consent Form.
  • The patient's legally authorized representative has signed the Informed Consent Form.
  • The patient has IS, diagnosed according to the International League Against Epilepsy (ILAE) criteria.
  • The patient is a full term (38 weeks gestation) male or female, aged >=1 month to <6 months at the time of enrollment.
  • The patient's length and body weight for gestational age is >=5th and <=95th percentile, according to Centers for Disease Control and Prevention (CDC) Growth Charts.

Exclusion Criteria:

  • The patient is currently being treated or has been previously treated with vigabatrin.
  • The patient is a member of the site personnel's immediate family.
  • The patient takes or has taken disallowed recent or concomitant medication or it is anticipated that the patient will require treatment with at least one of the disallowed concomitant medications during the study.
  • The patient has a history of severe drug allergy or hypersensitivity, or known hypersensitivity to the investigational medicinal product (IMP) or the excipients (povodone/iodine) of the IMP.
  • The patient has any other disorder for which the treatment takes priority over treatment of IS or is likely to interfere with study treatment or impair treatment compliance.
  • The patient has been treated with any IMP within 30 days or 5 half lives (whichever is longer) prior to the Screening Visit.
  • The patient has a disease or takes medication that could, in the investigator's opinion, interfere with the assessments of safety, tolerability, or efficacy, or interfere with the conduct or interpretation of the study.
  • The patient has been diagnosed or is judged by the investigator to have anemia.
  • The patient has been diagnosed or is judged by the investigator to have renal insufficiency.
  • The patient's parent or legally authorized representative is, in the investigator's opinion, unlikely or unwilling to comply with the protocol or the patient is unsuitable for any reason.
