Study Description

Brief Summary:

This study is a randomised, double-blind, placebo-controlled, sequential, ascending single-dose, parallel group study to evaluate safety, tolerability, biological activity, and systemic exposure of COVA322 (tumor necrosis factor alpha (TNF-α) / interleukin 17 A (IL-17A) antibody fusion protein) in patients with stable chronic moderate-to-severe plaque psoriasis. Patients will receive ascending single-doses of COVA322 or placebo as a constant-rate i.v. infusion, followed by 12 weeks of evaluation.

Condition or disease	Intervention/treatment	Phase
Plaque Psoriasis	Drug: COVA322; Other: Placebo	Phase 1; Phase 2

Study Design

• Study Type: Interventional (Clinical Trial)
• Actual Enrollment: 24 participants
• Allocation: Randomized
• Intervention Model: Parallel Assignment
• Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
• Primary Purpose: Treatment
• Official Title: A Randomised, Double-blind, Sequential, Ascending Single-dose Study to Evaluate Safety, Tolerability, Biological Activity, and Systemic Exposure of COVA322, a Bispecific TNF-α / IL-17A Antibody Fusion Protein, in Patients With Stable Chronic Moderate-to-severe Plaque Psoriasis
• Study Start Date: April 2014
• Actual Primary Completion Date: September 2015

Arms and Interventions

Arm	Intervention/treatment
Experimental: COVA322; single i.v. infusion	Drug: COVA322
Placebo Comparator: Placebo; single i.v. infusion	Other: Placebo

Outcome Measures

Primary Outcome Measures :

1. Occurrence of Adverse Events as a Measure of Safety and Tolerability [ Time Frame: Up to 12 weeks ]
   The safety and tolerability of COVA322 will be assessed by monitoring the occurrence of local and systemic adverse events or abnormalities as identified by physical examinations, safety lab, vital parameters, ECG and immune response/antibodies to COVA322.
