Brief summary
The purpose of this study is to evaluate different dose levels of IMO-3100 compared to placebo administered for 4 weeks to patients with moderate to severe plaque psoriasis.
Detailed description
To evaluate the safety, tolerability and treatment effect of different dose levels of IMO-3100 compared to placebo administered for 4 weeks to patients with moderate to severe plaque psoriasis.
Interventions

Saline for Injection 0.01 mL/kg SC q wk x 4 wk based on body weight at screening, not to exceed 1.25 mL
IMO-3100 at 0.32 mg/kg SC q wk x 4 wks based on body weight at screening, not to exceed 40 mg per injection

Recruitment details
This was a multicenter study conducted at 13 study centers in the Unites States (US).
Pre-assignment details
48 patients met inclusion/exclusion criteria; 4 were not randomized. The reasons for not randomizing these patients were: 2 patients withdrew consent, 1 whose calcium levels did not meet the criteria for randomization, and 1 for whom the study was closed prior to randomization
