Brief Summary
This is a 73-day phase II, open label trial of the true human monoclonal antibody RA-18C3 in subjects with moderate to severe plaque psoriasis. Ten (10) subjects will receive 200 mg of RA-18C3 via subcutaneous injection. Subjects will receive injections at Days 0, 21, and 42 for a total of 3 injections. Study drug will be administered under close observation in a facility equipped to handle medical emergencies. Subjects will not be discharged from the facility until at least 1 hour following the end of the injection or 1 hour after their vital signs have stabilized. Safety will be assessed by pre- and post-treatment serial measurements of vital signs, clinical laboratory assessments, and the recording of adverse clinical events.

Eligibility Criteria
You may qualify if:
- Subjects 18 years of age or older
- Diagnosis of plaque psoriasis for ≥ 6 months; INCLUDING subjects with chronic guttate lesions.
- Psoriasis area-and-severity index (PASI) score of ≥ 12
- Involvement of ≥ 5% of body-surface area
- For female subjects of childbearing age, a negative urine pregnancy test at screening and at specified time points throughout the trial. For subjects with reproductive potential, a willingness to utilize adequate, double barrier contraception during the study and including 3 months after study completion. Sexually active men must use an accepted method of contraception during the study and including 3 months after study completion.
- Signed and dated Institutional Review Board (IRB) approved informed consent before any protocol-specific screening procedures are performed
You may not qualify if:
- Treatment with any biologicals or investigational agents within the last 4 weeks (or 5 half-lives, whichever is longer).
- Treatment with conventional systemic psoriasis therapy within last 4 weeks
- Treatment with phototherapy within the last 4 weeks
- Topical psoriasis treatment with the last 2 weeks
- History of uncontrolled diabetes, unstable ischemic heart disease, active inflammatory bowel disease, active peptic ulcer disease, recent stroke (within 3 months), ongoing congestive heart failure, and any other condition which, in the opinion of the investigator, would put the subject at risk by participation in the protocol.
- Hemoglobin \<10.0 g/dL, WBC \<3.0 x 103/mm3, platelet count \<125 x 103/mm3, creatinine \> 1.5mg/dL, AST/ALT \>2 x ULN, alkaline phosphatase \>2 x ULN
- Known HIV antibody, hepatitis B surface antigen and/or hepatitis C antibody.
- History of malignancy within 5 years prior to study entry other than carcinoma in situ of the cervix, or adequately treated, non-metastatic squamous or basal cell carcinoma of the skin.
- History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies.
- History of tuberculosis (latent or active) or positive Interferon-gamma release assay (IGRA)
- Infectious disease:
- CRP \>30 mg/L, fever, or infection requiring treatment with antibiotics within 3 weeks prior to Screening
- Immunodeficiency
- History of treatment with Tysabri or Raptiva
- Female subjects who are pregnant, planning to become pregnant during the course of the study, or breast-feeding
