Primary Outcome(s)
|
Main Objective: To assess the efficacy of gabapentin relative to tramadol for the treatment of moderate to 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
|
Secondary Objective: 1. To assess effect of gabapentin relative to tramadol on quality of life (physical, emotional, social and school functioning) and global satisfaction with treatment. 2. To assess safety of gabapentin relative to tramadol for treatment of chronic neuropathic or mixed pain in children 3 months to less than 18 years of age. 3. To characterise the population pharmacokinetic-pharmacodynamic (PKPD) relationship of gabapentin liquid formulation and provide confirmation of the recommended paediatric dose. Additional exploratory objectives of the study are: 4. To describe the metabolomic profile following drug treatments. 5. To explore genetic polymorphisms and their impact on pharmacokinetics (PK) and pharmacodynamics (PD). 6. To assess the population pharmacokinetics of tramadol and, if feasible, its PKPD relationship in the paediatric population.
