Clinical Trial 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).

• Any other underlying conditions (including but not limited to metabolic, hematologic, hepatic, renal, pulmonary, neurological, endocrine, cardiac, gastrointestinal conditions and infections) that, in the opinion of the investigator, may affect the course of psoriasis, affect the assessment of signs/symptoms of psoriasis, or put patients using the study treatment at additional risk

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	• The Proportion (Number) of Patients in Each Study Arm Who Achieved a PASI 75 at Week 12 of Treatment	The Psoriasis Area and Severity Index (PASI) allows evaluating the extent and severity of skin symptoms of psoriasis. Body is divided into 4 areas for scoring (head, arms, trunk, legs); each area is scored by itself and scores are combined for final PASI: 0 (no disease) to 72 (maximal disease).; Relative (percentage) change in PASI score from baseline (screening) is calculated as 100 x (baseline value - time point t value) / (baseline value) PASI 75 indicates a 75% or greater reduction in PASI scores from baseline and is indicative of excellent disease improvement.	week 12
