About this study

Official title: Phase IIB Study to Evaluate the Safety and Efficacy of Topical Difluoromethylornithine and Topical Diclofenac in the Treatment of Sun-Damaged Skin on the Forearm

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of eflornithine and diclofenac may stop cancer from growing in patients with sun-damaged skin.

PURPOSE: This randomized phase II trial is studying the side effects and how well eflornithine works compared with diclofenac, given alone or together, in treating patients with sun-damaged skin.

Read the detailed description

OBJECTIVES:

Primary

  • To determine if combination therapy with topical eflornithine hydrochloride ointment and topical diclofenac sodium gel over 3-months increases the efficacy versus either agent used alone in the treatment of moderately sun-damaged skin.

Secondary

  • To evaluate the safety of sequential administration of topical eflornithine hydrochloride ointment and topical diclofenac sodium gel.
  • To determine the correlation of karyometric changes with histopathologic, immunohistochemical, clinical, and genetic polymorphism data.
  • To obtain materials for microarray analysis.

OUTLINE: Patients are randomized to 1 of 3 treatment arms.

  • Eflornithine hydrochloride : Patients apply topical eflornithine hydrochloride ointment to their left forearm twice daily on days 1-90.
  • Diclofenac sodium : Patients apply topical diclofenac sodium gel to their left forearm once daily on days 1-90.
  • Eflornithine hydrochloride/Diclofenac sodium : Patients apply topical eflornithine hydrochloride ointment as in arm I twice daily and topical diclofenac sodium gel as in arm II once daily on days 1-90.

Prior to treatment, three 4-mm punch biopsies are taken from the skin of the left lateral forearm for assessment of histopathology, the cyclooxygenase-2 enzyme and p53 expression, apoptosis, and nuclear chromatin karyometry. Tissue is also obtained for future use in microarray analysis. Blood is drawn for assessment of ornithine decarboxylase polymorphisms and for banking for subsequent studies. Biopsies are repeated 2-3 weeks after completion of treatment.

Digital photographs are taken at baseline and 1-2 weeks after completion of study therapy to document improvement of sun damage, appearance of new skin lesions, and toxicity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes in Putrescine Over 3 Months

    Putrescine is measured in nmole/g skin per biopsy. Baseline and End of Study biopsies were measured and the change was produced by subtracting baseline levels from End of Study levels. There was one baseline biopsy and one End of Study biopsy per participant.

    Measured: 3 months

  2. Safety of Combination Therapy With Topical Eflornithine Hydrochloride Ointment and Topical Diclofenac Sodium Gel Over 3-months

    Adverse events were compared across three treatment groups by severity determined by the clinician. All adverse events were resolved by the end of follow up.

    Measured: 3 months

Secondary outcomes (1)
  1. Change in Histologic Score Diagnosis and Treatment Group

    Change scores were computed by subtracting baseline histologic score from End of Study histologic score. Slides were formalin fixed. Histologic Score has been developed by this research group over the course of Grant (reference below). A standardized form captures data on the following criteria: basal or suprabasilar pleomorphism (atypia); inflammation; hyperkeratosis; parakeratosis. The atypia and inflammation were rated as: none (0), mild to moderate(1), and severe (2). The remaining criteria were rated as present (1) or absent (0). Histologic Scores were computed by adding together the codes for the histologic criteria. Higher scores reflected higher level of epidermal /dermal damage.

    Measured: 3 months

A Phase 2 study testing Diclofenac Na gel and Eflornithine HCL ointment in people with Other Benign Neoplasm of Skin, Unspecified, run by University of Arizona at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 25 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in Putrescine Over 3 Months (time frame: 3 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00601640, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Mar 2017.
