- Target Recruitment
- Not specified
- Subject must voluntarily give written informed consent
- Subject must be between 18 and 70 years of age
- Subject must have chronic plaque psoriasis and stable plaques in an area sufficient for six treatment fields
- The physical examination must be without disease findings unless the investigator considers an abnormality to be irrelevant to the outcome of the study
- Sexually active females of childbearingpotential shoud either be surgically sterile (hysterectomy of tubal ligation), or should use a highly effective medically accepted contraceptive regimen. A highly effective method of birth control is defined as those which result in a lower failure rate (i.e. less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some IUDs, sexual abstinence or vasectomised partner. For subjects using a hormonal contraceptive method, information regarding the product under evaluation and its potential effect on the contraceptive should be addressed.
