Scientific titleEfficacy of methotrexate on chronic calcium pyrophosphate dihydrate deposition disease (chondrocalcinosis) - a randomised controlled trial
Study objectivesMethotrexate is efficient in controlling symptoms and signs of chronic chondrocalcinosis.
Ethics approval(s)Ethics approval received from Swissmedic, the Swiss Agency for Therapeutic Products on the 2nd July 2007 (ref: 2007DR3150; protocol: 06-167)
Health condition(s) or problem(s) studiedChronic calcium pyrophosphate dihydrate (CPPD) arthropathy
InterventionPatients will be randomised to receive either methotrexate (10 - 15 mg/week intramuscular [im] injections) or placebo during an initial treatment period of three months, followed by a wash-out period of one month, and a subsequent treatment period of three months with the alternative regimen. The total duration of follow-up will be eight months (three months in one arm and two months wash-out and three months in the other arm).
Intervention typeDrug
PhaseNot Specified
Drug / device / biological / vaccine name(s)Methotrexate
Primary outcome measure(s)

The primary outcome will be arthritic disease activity, measured by the DAS44 (disease activity score on 44 joints), and pain levels, measured by a patient visual analogue scale.

Key secondary outcome measure(s)

Secondary outcomes will be:
1. Number of acute arthritis flares
2. Patient’s global assessment
3. Function of the target joints
4. Erythrocyte sedimentation rates
5. Number of tender and swollen joints
6. Number of analgesic pills
7. Safety and tolerability of methotrexate
