Topical Perillyl Alcohol in Treating Patients With Sun Damaged Skin and Actinic Keratoses

• Status: Completed
• Trial end date: 2009-06-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy, such as perillyl alcohol, work in different ways to stop the growth of abnormal cells, either by killing the cells or by stopping them from dividing. It is not yet known which dose of topical perillyl alcohol is more effective in stopping the development of cancer in sun damaged skin.

PURPOSE: This randomized phase II trial is studying high-dose topical perillyl alcohol to see how well it works compared with low-dose topical perillyl alcohol in treating patients with sun damaged skin and actinic keratoses.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: University of Arizona
• Collaborators: Arizona Disease Control Research Commission; National Cancer Institute (NCI)
• Treatments: Ethanol; Perilla alcohol; Perillyl alcohol

Criteria

DISEASE CHARACTERISTICS:

• Resident of Pima or adjoining Southern Arizona county

• Patients outside of Pima County are also eligible

• Sun damaged skin as judged by the study physician and quantifiable, clinically diagnosed, and visible actinic keratoses (AK) on both dorsal forearms, with at least two AK on each arm

• AK lesions must not be clustered, confluent, or too numerous to count accurately

• Presence of AK on sites other than the test area allowed

• No significant inflammation or irritation of the skin of the upper extremities that is not clinically diagnosed as sun damage or AK

• Patients must agree to limit sun exposure as much as possible and may continue their normal pattern of sunscreen use

PATIENT CHARACTERISTICS:

Inclusion criteria:

• Females must not be of childbearing potential, and therefore must be post-menopausal or surgically sterile by hysterectomy

• Not pregnant or nursing

Exclusion criteria:

• Concurrent skin malignancy or disorder of the upper extremities

• Patients with Squamous cell carcinoma or basal cell carcinoma in an area other than the test area are eligible upon excision of the Squamous cell carcinoma or basal cell carcinoma

• Patients who are immunosuppressed by virtue of medication or disease

• Serious concurrent illness that could interfere with study regimen

• Invasive cancer within the past 5 years

PRIOR CONCURRENT THERAPY:

• At least 30 days since prior topical medications to the skin of the upper extremities except for emollients or sunscreens

• At least 30 days since prior and no concurrent mega-doses of vitamins, defined as any of the following:

• More than 5 times the recommended daily allowance

• More than 5 capsules of multivitamins

• 400 IU of vitamin E

• 200 μg of selenium

• 1 gm of vitamin C

• At least 6 months since prior and no concurrent therapy for squamous cell carcinoma (SCC) or basal cell carcinoma (BCC) anywhere in the test area (i.e., the forearms or hands)

• Treatment for Squamous cell carcinoma or basal cell carcinoma on sites other than the test area is allowed

• At least 4 weeks since prior surgical biopsy, surgical excision, or cryotherapy for AK in the test area and the sites must have healed

• At least 6 months since prior topical treatment (e.g., 5-fluorouracil or imiquimod) for AK

• No concurrent therapy that may interfere with clinical evaluations

• No concurrent topical drug treatment (e.g., retinoids, aminolevulinic acid, diclofenac sodium, imiquimod, or fluorouracil) to any area of skin, including test area

• No concurrent enrollment in another clinical trial

• No concurrent topical citrus peel or consumption of citrus peel
