Combination Therapy With 5-FU and PDT for the Treatment of Post-transplant Premalignant Skin Disease - Full Text View

Purpose

This randomized, intra-patient comparative study is designed to investigate the combination regimen of 5-FU and PDT, versus PDT alone, for its ability to generate significantly elevated levels of the target photosensitizer, PpIX, in lesions of actinic keratoses (AKs) and to more effectively treat and prevent recurrence of AKs. The target population comprises patients with solid organ transplants (renal, hepatic), as well as normal (immunocompetent) subjects to control for possible influences of immunosuppression.

Primary Outcome Measures:

Accumulation of PpIX [ Time Frame: Day 7 of the study ]
The primary endpoint of this study will be the accumulation of PpIX at 3 h after MAL application (measured noninvasively, in each treated region).

(Region refers to the half-face or half-scalp area treated with PDT monotherapy, or the contralateral area treated with the 5-FU/PDT combination regimen).

Secondary Outcome Measures:

AK clearance [ Time Frame: At Day 14 and at 3 months post-treatment ]
1) Rate of AK clearance at Day 14 (at the time of suture removal) and at 3 months
Development of new AKs [ Time Frame: At 3, 6, 9, and 12 months post-treatment ]
Rate of development of new AK at months 3, 6 9, and 12

Arms	Assigned Interventions
Experimental: Solid Organ Transplant with AKs Patients who have undergone kidney or liver transplant within 2 years and have at least 4 premalignant skin lesions on the face, ears, scalp, forearms and/or dorsal hands. Patients will serve as their own control, and one side of the body will be randomized to either 5-FU plus PDT, and the other will receive PDT alone.	Drug: 5-Fluorouracil All patients will receive one cream, 5-Fluorouracil, and will be instructed to apply the cream according to the randomization schema to AKs on either the right or left side of the face/scalp once a day for 6 days prior to PDT. A baseline measurement of the tumor's ability to produce PpIX will be done by applying methyl-aminolevulinic acid (Metvixia® topical cream) to the selected AKs and using the Aurora© dosimeter. Prior to Metvixia, and again 3 hours after application, surface measurements of the PpIX fluorescence will be taken. Then, the two largest precancer lesions (one on the left side, one on the right side) will be biopsied under local anesthesia, followed by red light PDT (lasting ~8 minutes). The biopsy sites will be shielded from the light with a circular spot bandage. Other Names: Fluorouracil Cream, USP 5% 5-FU
Active Comparator: Actinic Keratoses Patients with at least 4 actinic keratoses on the face, ears, scalp, forearms and/or dorsal hands. Patients will serve as their own control, and one side of the body will be randomized to either 5-FU plus PDT, and the other will receive PDT alone.

Detailed Description:

This clinical trial will test a new combination of 5-fluorouracil cream (5FU) and methylaminolevate photodynamic therapy (MAL-PDT), versus MAL-PDT alone, as treatment for actinic keratoses (AKs) in immunosuppressed organ transplant recipients (OTRs) and an immunocompetent control group. Objectives: 1) Determine whether topical pretreatment with 5-FU selectively increases the amount of photosensitizer (PpIX) produced within AK lesions, relative to non-pretreated lesions. 2) Determine whether the combination treatment improves lesion resolution and reduces the incidence of new AKs. 3) Determine whether biomarkers in tissue and blood are predictive of patient responsiveness to 5FU (PpIX induction, new lesion incidence, and clinical toxicity).

20 organ transplant recipients and 20 normal patients, with AKs on face, scalp, ears, forearms or back of the hand are enrolled through Dermatology and Transplant Clinic at Cleveland Clinic. Women of childbearing age must use contraception and have a negative pregnancy test.

Study participants will apply 5FU daily for 6 days; MAL/PDT is administered on 7th day. PpIX will be measured in lesions using a noninvasive dosimeter. Biopsies will be taken from selected lesions, and AKs will be photographed. Participants will be asked to complete a questionnaire to document adverse events. Patients are evaluated at day 14, and months 3, 6, 9, 12, to document AK clearance and new lesion appearance.
