Study of SOR007 Ointment for Actinic Keratosis

Inclusion Criteria

• •Signed informed consent.
• •Men and women with actinic keratosis.
• •Age 45-85.
• •Women who have had surgical sterilization or are post-menopausal (absence of menses for at least one year) are eligible. Women of child-bearing potential who are non-pregnant, non-nursing, and willing to avoid pregnancy during the course of the study and during the menstrual cycle following completion of their participation in the study are eligible. (Adequate contraception is defined as regular use of diaphragm with condoms, IUD with condoms, or systemic contraceptives if used for at least three months prior to enrollment in the study.) A negative pregnancy test is required as an entry criteria. Women must continue to use the method of contraceptive for at least 30 days after the last administration of study drug.
• •Male subjects must agree to sexual abstinence or use adequate contraception when sexually active in combination with their female partners, if they are of childbearing potential. That means the volunteer must be vasectomized or use a condom and his female partner must either be surgically sterile (hysterectomy or tubal ligation) or agree to use a reliable method of contraception with a failure rate of less than 1% per year when used consistently and correctly such as implants, injectables, combined oral contraceptives, or non-DalKon Shield IUDs. This applies from signing of informed consent form until 90 days after the last study drug administration. Methods of contraception must have been effective for at least 30 days on the day of signing of informed consent. Male volunteers must also refrain from sperm donation from the time of singing informed consent form until 90 days after the last study drug administration.
• •Presence of 4-8 AK lesions total in a 25 cm2 area identified on the face through transparency mapping and photographs. The face area will be defined from hair line to jaw line. The scalp will not be included. An imaginary normal hair line will be the upper boundary for bald men.
• •Able to refrain from the use of all other topical medications to the facial area during the treatment period.
• •Considered reliable and capable of understanding their responsibility and role in the study.
