Official Title: | An International Prospective, Double-blind, Placebo-controlled Phase III Randomised Controlled Trial (RCT) in Patients With Moderate to Severe Psoriasis Are Treated With Subcutaneous (s.c.) Methotrexate Using an Optimized Treatment Schedule. |

Arm | Intervention/treatment |
---|---|
Active Comparator: methotrexate
Once weekly (every 7 days) s.c. administration of 17.5 mg MTX. If PASI50 is not reached after 8 weeks (week 8) or PASI75 is not reached after 24 weeks, the dosing will be increased to 22.5 mg MTX/week. If patients were already dosed with 22.5 mg MTX/week in week 24 and PASI50 is not reached, patients will be excluded from treatment. Primary endpoint after 16 weeks.

Drug: Methotrexate
methotrexate 50 mg/ml in syringes for sub-cutaneous injection; Once weekly (every 7 days) s.c. administration of 17.5 mg MTX; If PASI50 is not reached after 8 weeks, the dosing will be increased to 22.5 mg
Other Name: MTX |
Placebo Comparator: Placebo (NaCl-Solution)
Once weekly (every 7 days) s.c. administration of 0.35 mL placebo If PASI50 is not reached after 8 weeks (week 8), the dosing will be increased to 0.45 mL placebo/week. Primary endpoint after 16 weeks. After 16 weeks patients will receive 17.5 mg MTX / week. If PASI50 is not reached after 8 weeks of MTX treatment (week 24), uptitration to 22.5 mg MTX/ 0.45 mL Plac / week will be done. Patients, who will reach PASI75 under placebo treatment after 16 weeks, will be dosed neither with placebo nor with MTX until relapse. After relapse the patients will be dosed with a starting dose of 17.5 mg MTX / week.
