Condition: Moderate to Severe Plaque Psoriasis
MeSH terms: Psoriasis
Intervention: BCD-085 Q2W; BCD-085 Q4W; Placebo
Intervention description: In Arm 1, the test drug BCD-085 will be used at a dose of 120 mg given as two SC injections according to the following schedule: once a week for the first 3 weeks (induction treatment) and then once every 2 weeks through Week 10.
On Week 12, the treatment efficacy will be assessed with a PASI75 score, and the therapies will be unblinded. During the open-label patients will receive BCD-085 through week 50. The follow-up will continue through week 54.; In Arm 2, and then once every 4 weeks through Week 10. On Week 12, the treatment efficacy will be assessed with a PASI75 score, and the therapies will be unblinded. During the open-label period, patients from Arm 2 will be given BCD-085 once every 4 weeks through week 50.

Summary:

      BCD-085 is an innovative drug, a monoclonal antibody against interleukin-17. The toxicity,
      safety, and pharmacokinetics of BCD-085 were investigated in animals, in phase I clinical
      study in healthy volunteers, and in phase III clinical study in patients with moderate to
      severe plaque psoriasis. This clinical study aims at investigating the efficacy and safety of
      BCD-085 every other week regimen (after induction for the first 3 weeks) versus BCD-085 one
      per month regimen (after induction for first 3 weeks) versus placebo in patients with
      moderate to severe plaque psoriasis.

      Study purpose:

      To investigate the efficacy and safety of BCD-085 versus placebo in patients with moderate to
      severe plaque psoriasis (psoriasis vulgaris)

      Study objectives:

        1. To compare the efficacy of BCD-085 every 2 weeks versus BCD-085 every 4 weeks versus
           placebo, based on the proportion of patients who achieved a PASI75, target sPGA score,
           and on other secondary efficacy measures.

        2. To evaluate the proportion of patients in each study arm who develop adverse events with
           multiple injections of BCD-085 and placebo. Compare the safety profiles of BCD-085 when
           used every 4 weeks and when used every 2 weeks.

        3. 4. To assess the immunogenicity of BCD-085 defined as the proportion of patients who
           develop anti-drug antibodies (binding or neutralizing).
