Experimental: TSO 7500
Subjects in this arm will receive doses of 7500 trichuris suis ova every two weeks, starting at the baseline visit, for a total of 8 doses.

During the treatment phase, study drug will be provided in a liquid form and will be administered every 2 weeks, starting with the Baseline visit, through Week 14.
Other Name: TSO 7500
- Physician's area and severity index (PASI) [ Time Frame: Screening, baseline, weeks 2, 4, 6, 8, 10, 12, 14, and 16 ]The PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. PASI produces a numeric score that can range from 0 to 72 based on the body surface area of involvement and the severity of disease (induration, erythema and scale). A PASI-50 response is defined as ≥50% improvement in PASI score from baseline; PASI-75 and PASI-90 are similarly defined.
- Safety and tolerability [ Time Frame: Screening, baseline, weeks 2, 4, 6, 8, 10, 12, 14, 16, 20, and 38 ]Evaluated via the frequency and severity of adverse events, changes in physical examinations, stool studies (ova and parasites, culture, clostridium difficile toxin, and blood), clinical laboratories (liver function tests, creatine phosphokinase, complete metabolic profile, complete blood count), and vital signs (blood pressure, pulse and temperature).
