Actinic Keratosis Study (AK)

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Lynn Cornelius, MD, Washington University School of Medicine
ClinicalTrials.gov Identifier:
NCT02019355
First received: December 10, 2013
Last updated: May 18, 2016
Last verified: December 2013
  Purpose
The main purpose of this study is to determine the effectiveness of a new combination therapy for actinic keratosis. This study investigates a new indication for an FDA-approved topical medication, calcipotriol, for treatment of actinic keratosis, including how well it works and how safe it is when used in combination with the standard of care medication (5-fluorouracil) for the skin condition.

Condition Intervention Phase
Actinic Keratosis
Drug: 5-fluorouracil 5% cream
Drug: Calcipotriol 0.005% ointment
Drug: Vaseline
Early Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: The Role of Calcipotriol in Treatment of Pre-cancerous Skin Lesions

Primary Outcome Measures:
  • percentage of change in the number of actinic keratoses from baseline [ Time Frame: 8 weeks ]
    To compare the efficacy of topical 5-fluorouracil+calcipotriol vs. 5-fluorouracil alone in treatment of actinic keratosis in patients with multiple actinic keratoses at each of the four anatomical sites (scalp, face, right upper extremity and left upper extremity). The outcome of interest is percentage change from baseline number of actinic keratoses in the target treatment area on scalp, face, right upper extremity and left upper extremity at 8 weeks after treatment.


Secondary Outcome Measures:
  • complete and partial (>75%) clearance of actinic keratoses [ Time Frame: 8wks ]
    o To determine complete and partial (>75%) clearance of actinic keratoses at 8 weeks after treatment.

  • Composite score of erythema, itching and skin pain after topical 5-fluorouracil+calcipotriol vs. 5-fluorouracil alone treatment of actinic keratoses [ Time Frame: 4days ]
    To determine the composite scores of erythema, itching and pain (determined using standardized scales) following topical application of 5-fluorouracil+calcipotriol vs. 5-fluorouracil alone at the end of the 4-day treatment period.

  • Induction of TSLP expression in keratinocytes by calcipotriol [ Time Frame: 4 days ]
    To examine the induction of TSLP expression in keratinocytes by calcipotriol at the site of the actinic keratoses at the end of 4-day treatment of course.

  • differences in response to topical 5-fluorouracil+calcipotriol vs. 5-fluorouracil alone between the four anatomical sites [ Time Frame: 8wks ]
    To determine any differences in response to topical 5-fluorouracil+calcipotriol vs. 5-fluorouracil alone between the four anatomical sites at 8 weeks after treatment.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Age of at least 50 years
  • Presence of four to fifteen clinically typical, visible, and discrete actinic keratoses in 25 cm2 on any of the four anatomical sites: scalp, face, right upper extremity and left upper extremity
