Summary

RATIONALE: Drugs used in chemotherapy, such as tazarotene, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This randomized phase II trial is comparing two different schedules of topical tazarotene and topical placebo to see how well they work in treating patients with basal cell skin cancer and basal cell nevus syndrome on the chest.

Clinical Details

Official title: A Phase II Randomized, Double-Blind, Vehicle-Controlled, Crossover Clinical Trial of Tazarotene 0.1% and Vehicle Cream Each Applied Once-Daily for 12 or 24 Months in Subjects With Basal Cell Nevus Syndrome

Study design: Allocation: Randomized, Masking: Double-Blind, Primary Purpose: Treatment

Primary outcome:

Reduction in the observed numbers of basal cell carcinomas ≥ 9 mm² in diameter

Parameters of safety

Adverse events according to NCI CTCAE v3.0

Detailed description: OBJECTIVES: Primary

- To expand and refine chemopreventive strategies in individuals with basal cell nevus

syndrome (BCNS) on the chest and back, who are at high risk for the development of basal cell carcinomas (BCCs).

- To determine whether tazarotene 0. 1% cream applied to the chest for two years will

reduce the numbers of basal cell carcinomas (BCCs) observed, as compared to the number expected, based on changes in BCC numbers observed during months 0-12. Secondary

- To compare the difference in total BCC burden (measured as the total lesion surface

area) between chest and back over various time points and aggregated intervals of interest.

- To determine whether there are any detectable wash-in or wash-out periods for the

tazarotene effects.

- Explore the use of a random effects model for longitudinal analysis of total lesions

over time. OUTLINE: This is a multicenter study. Patients are randomized into 1 of 2 arms.

- Arm I: Patients apply 0. 1% tazarotene cream on months 0-12 and vehicle (placebo) on

months 13-36 once daily to the chest in the absence of disease progression or unacceptable toxicity.

- Arm II: Patients apply vehicle (placebo) on months 0-12 and 0. 1% tazarotene cream on

months 13-36 once daily to the chest in the absence of disease progression or unacceptable toxicity. Treated chest and untreated back is evaluated at 3 month intervals for 36 months.

Eligibility

Minimum age: 18 Years. Maximum age: 75 Years. Gender(s): Both.

Criteria:

DISEASE CHARACTERISTICS:

- Histologically or clinically diagnosed with at least 3 basal cell carcinomas (BCCs) ≥

9 mm² in diameter on both the chest and back within the past year

- Meets above criterion as well as one additional major criterion or two minor

criteria:

- Major criteria:

- More than 2 histologically confirmed BCCs (1 for patients under the age of

20 years)

- Odontogenic keratocysts of the jaw proven by histology

- Three or more palmar and/or plantar pits

- Bilamellar calcification of the falx cerebri (if less than 20 years old)

- Fused, bifid, or markedly splayed ribs

- First degree relative with basal cell nevus syndrome (BCNS)

- PTCH1 gene mutation in normal tissue

- Minor criteria:

- Macrocephaly determined after adjustment for height

- Congenital malformations (e. g., cleft lip or palate, frontal bossing,

"coarse face", moderate or severe hypertelorism)

- Skeletal abnormalities (e. g., Sprengel deformity, marked pectus deformity,

or marked syndactyly of the digits)

- Radiological abnormalities (e. g., bridging of the sella turcica, vertebral

anomalies such as hemivertebrae, fusion or elongation of the vertebral bodies, modeling defects of the hands and feet, or flame shaped lucencies of the hands or feet)

- Ovarian fibroma

- Medulloblastoma

PATIENT CHARACTERISTICS:

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception

- No history of invasive cancer within the past five years except nonmelanoma skin

cancer, stage I cervical cancer, or stage 0 chronic lymphocytic leukemia

- No history of hypersensitivity to any of the ingredients in the study medication

formulations

- No uncontrolled systemic disease, including known HIV positivity

- No history of other skin conditions or significant illness that would interfere with

evaluation of the study medication

- No history of any condition or situation that, in the opinion of the Investigator,

might interfere with the patient's ability to comply with the protocol or pose additional or unacceptable risk to the patient

- Able to return for follow-up tests

PRIOR CONCURRENT THERAPY:

- No prior topical or systemic therapies that might interfere with the evaluation of

the study medication including the following:

- Glucocorticoids (other than ≤ 1% triamcinolone)

- Retinoids (e. g., etretinate, isotretinoin, tazarotene, tretinoin, adapalene)

within the past six months

- Alpha-hydroxy acids (e. g., glycolic acid, lactic acid)

- At least 6 months since prior 5-fluorouracil or imiquimod (except as treatment

to discrete basal cell carcinomas)

- At least 30 days since prior systemic investigational medication or any topical

investigational medication to the chest or back

- At least 1 year since prior treatment with systemic chemotherapy

- No concurrent non-study topical medications to the skin of the chest and back,

including prescription and over the counter preparations (e. g., corticosteroids [other than ≤ 0. 1% triamcinolone applied no more than 6 times/month] or vitamin A)

- Concurrent moisturizers and emollients are allowed

- Patients must use sunscreen (SPF ≥ 15) at least once daily on all exposed skin sites

during study treatment
