Intervention(s)
|
Product Name: gabapentin Pharmaceutical Form: Syrup INN or Proposed INN: gabapentin hydrochloride CAS Number: 60142-95-2 Current Sponsor code: not applicable Other descriptive name: GABAPENTIN HYDROCHLORIDE Concentration unit: mg/ml milligram(s)/millilitre Concentration type: equal Concentration number: 75- Pharmaceutical form of the placebo: Syrup Route of administration of the placebo: Oral use

Primary Outcome(s)
|
Secondary Objective: 1.To assess the effect of gabapentin as adjunctive therapy to morphine compared to morphine alone on quality of life (physical, emotional, social and school functioning) and global satisfaction with treatment. 2.To assess the safety of gabapentin combined with morphine compared to morphine alone in the treatment of severe neuropathic or mixed pain in children from 3 months to less than 18 years of age. 3.To characterise the population pharmacokinetic-pharmacodynamic (PKPD) relationship of gabapentin liquid formulation with and without morphine and provide confirmation of the recommended paediatric dose. Additional exploratory objectives of the study are: 4.To explore the metabolomic profile of drug treatments. 5.To explore genetic polymorphisms and their impact on pharmacokinetics (PK) and pharmacodynamics (PD).
|
Main Objective: to evaluate the efficacy of gabapentin as adjunctive therapy to morphine in the treatment of severe chronic neuropathic or mixed pain in children from 3 months to less than 18 years of age assessed by the difference in average pain scores between treatment arms at the end of the treatment period.
