Lovastatin in Treating Patients At High Risk of Melanoma

A Randomized, Double-Blind, Placebo-Controlled Phase II Clinical Trial of Lovastatin for Various Endpoints of Melanoma Pathobiology

The use of lovastatin may slow disease progression in patients at high risk of melanoma. It is not yet known whether lovastatin is more effective than a placebo in treating patients at high risk of melanoma. This randomized phase II trial studies how well giving lovastatin or placebo works in treating patients at high risk of melanoma.

Study Overview

• Status: Completed
• Conditions: Precancerous Condition; Stage II Melanoma; Stage 0 Melanoma; Stage I Melanoma
• Intervention / Treatment: Procedure: biopsy; Other: placebo; Procedure: laboratory biomarker analysis; Drug: lovastatin

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the primary endpoint of the trial, by analysis of histopathologic regression of atypical nevi in response to a 6-month trial of oral (PO) lovastatin vs. placebo in subjects with atypical nevi.

SECONDARY OBJECTIVES:

I. To evaluate clinical regression of atypical nevi in the lovastatin vs. placebo group.

II. To evaluate the secondary endpoint of changes in nevi numbers on subjects' backs in the lovastatin vs. placebo groups.

III. To evaluate a number of molecular biomarkers as secondary endpoints in the lovastatin vs. placebo groups.

IV. To evaluate the correlation of serum markers known to be affected by lovastatin with the endpoints chosen above.

V. To evaluate the safety and tolerability of the dosing regimen, and the dose escalation.

OUTLINE: Patients are randomized into 1 of 2 treatment arms per group.

ARM I: Patients (with two matched nevi OR one large nevi) receive lovastatin PO once daily (QD) for up to 6 months in the absence of disease progression or unacceptable toxicity.

ARM II: Patients (with two matched nevi OR one large nevi) receive placebo PO QD for up to 6 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 2 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Histopathologic Regression of Target Atypical Nevi With Treatment - Pathologist 1's Evaluation	The level of atypia will be graded in a standard fashion which leads to seven levels of atypia, with zero being no atypia and six being a melanoma. For each patient, the change from baseline in the level of atypia was calculated. Only the Two Matched Nevi Group - Lovastatin and Two Matched Nevi Group - Placebo data were used and analyzed for the primary outcome. One-Large Nevi Group - Lovastatin and One-Large Nevi Group - Placebo sample data were not used or analyzed due to insufficient numbers.	From baseline up to 24 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical Regression of Atypical Moles - Average of Three Reviewers' Evaluations	From close-up photos of target atypical nevi, lesions will be graded clinically. After unblinding of pre- or post-treatment status for photos, the grading score was as follows: 1= Post-treatment (Post-TX) photo shows a complete resolution of atypia relative to pre-treatment (Pre-TX) photo, 2 = Post-TX photo shows a strong lessening of atypia relative to Pre-TX photo, 3 = Post-TX photo shows a mild lessening of atypia relative to Pre-TX photo, 4 = Post-TX and Pre-TX photos show same degree of atypia, 5 = Pre-TX photo shows a mild lessening of atypia relative to Post-TX photo, 6 = Pre-TX photo shows a strong lessening of atypia relative to Post-TX photo, 7 = Pre-TX photo shows a complete resolution of atypia relative to Post-TX photo.
