The first pediatric formulation of vigabatrin

Kigabeq® : a pediatric formulation of the antiepileptic drug vigabatrin

The evaluation of Kigabeq® by the European Medicine Agency (EMA) has been completed and the Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for Kigabeq® on 26 July 2018, recommending the issuance of a European marketing autorisation. Kigabeq® has been exclusively developed for young children (1 – 7 years) and will thus benefit from a Pediatric Use Marketing Autorisation (PUMA).

Kigabeq® is a pediatric formulation of the antiepileptic drug vigabatrin which inhibits the GABA transaminase enzyme. Vigabatrin has been marketed throughout Europe since 1989 and in the USA since 2009 (Sabril®). Vigabatrin is currently approved for the treatment of infantile spasms and pharmaco-resistant focal-onset seizures (partial seizures).

Infantile spasms is a rare and devastating form of epileptic encephalopathy with peak incidence at about 6 months of age. It is an orphan disease with about 2,500 new annual cases in Europe. If left untreated, the prognosis is poor with deleterious effect on brain maturation and cognitive development.

Unmet medical need in pediatric patients

The EMA, in the “Revised priority list for studies into off-patent pediatric medicinal products” published in 2014 underlined the need of an “age-appropriate formulation” of vigabatrin. The formulation of Kigabeq® fully responds to this need.

Kigabeq® allows precise and convenient dosage of vigabatrin

  • Bioequivalent to Sabril™ sachet,
  • 100 mg and 500 mg scored soluble tablets with fast water dispersion (< 30 seconds),
  • 50 mg dosing steps for dose-to-bodyweight adjustment and titration of the drug,
  • Possibility to obtain concentrated solutions, 
  • Easy handling for care givers, 
  • No wastage of the medicine.
