Trial in Patients With Psoriasis Treated With Methotrexate Using an Optimized Treatment Schedule (METOP)
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.
This is a multicenter, multinational (12 centers planned, in Germany 9 centers and in France, the Netherlands and the United Kingdom (UK) 1 center in each country respectively), randomized, double-blinded, placebo-controlled study. The primary objective is to evaluate the efficacy of methotrexate (MTX) in patients with moderate to severe Psoriasis compared to Placebo as assessed by the primary endpoint "75% reduction of Psoriasis Area Severity Index" (PASI 75 ) during a 16 week treatment phase. As secondary objectives the safety and efficacy of the optimized treatment schedule will be assessed using multiple methods (e.g. (Serious) Adverse Events ((S)AE) occurrence and questionnaires)
The present study was initiated to further increase the knowledge about the optimal dosing regimen and to thus optimize the efficacy and safety of MTX treatment for patients with moderate to severe psoriasis. In view of the described risk-benefit profile of MTX, an initial dose of at least 15 mg per week administered subcutaneously followed by 5 mg folic acid p.o. 24 hours after MTX application seems appropriate. Since 20 mg MTX per week has been proven to be beneficial in a considerable part of patients, who did not respond sufficiently to 15 mg MTX per week, in this study the dosing starts with a dose of 17.5 mg MTX per week, administered subcutaneously. At such a starting dose, it was expected to find the highest MTX efficacy possible, but with appropriate safety margins. If in a patient, a "50% reduction of Psoriasis Area Severity Index" PASI50 response is not achieved in week 8, the dose will be increased to 22.5 mg MTX per week. All dosages used in this study lay within the approved dosing range of MTX. The study will be conducted in a double-blind, placebo controlled manner. Placebo was chosen as control since only this comparator allows a reliable interpretation of safety and efficacy data.

Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Psoriasis Vulgaris
  • 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
  • Drug: Placebo ( for Methotrexate)
    NaCl-Solution manufactured to mimic Methotrexate
  • 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.
    Intervention: Drug: Methotrexate
  • 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.
    Intervention: Drug: Placebo ( for Methotrexate)
