| Key inclusion criteria | 1. Screening phase (pre-randomisation): a. Definite diagnosis of JIA with onset before the 16th birthday (Cimaz & Fink 1996 - href=¿http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?holding=f1000&cmd=Retrieve&db=PubMed&list_uids=8882046) b. Patients starting methotrexate for the first time (oral, subcutaneous [SC] or intramuscular [IM] 8-12.5 mg/m^2 once a week) c. At least two other abnormal variables of any of the six core set parameters. The physician and the parents' ratings must both be at least one on a 10 cm Visual Analogue Scale (VAS), and the Childhood Health Assessment Questionnaire (CHAQ) score greater than zero 2. Trial phase (post-randomisation): a. Only patients who fail to respond to at least four but no more than six months of treatment with a standard dose of methotrexate (oral, SC or IM 8-12.5 mg/m^2 once a week) according to the definition of improvement will be randomised to receive either medium dose parenteral methotrexate (SC or IM 15 mg/m^2 once a week, max dose 20 mg a week) in the randomised phase of the trial b. Patients must be on a stable dose of no more than one Non-Steroidal Anti-Inflammatory Drugs (NSAID) for at least one month before the randomised period, and during the trial c. Low dose steroids (0.2 mg/kg/day [max 10 mg/day]), if administered, will be maintained below 0.2 mg/kg/day (max 10 mg/day) one month before enrolment in the randomisation phase, and throughout the trial d. Females of child bearing potential must have a negative pregnancy test at the beginning of the trial. If sexually active, they must agree to use adequate contraception (i.e. oral contraceptive, diaphragm with spermicidal cream, or Intra-Uterine Device [IUD]), throughout study participation, and must have no intention of conceiving a child during the course of the study. e. Ability of the patients and/or parents to communicate meaningfully with the investigational staff, and competence to give written informed consent and/or assent, and ability to comply with the entire study procedures is essential f.
