Vitamin D as a Nutritional Neoadjuvant During Photodynamic Therapy of Basal Cell Carcinoma
Vitamin D as a Nutritional Neoadjuvant During Photodynamic Therapy of Basal Cell Carcinoma in Basal Cell Nevus Syndrome
The purpose of this study is to study 50 patients with multiple Basal Cell Carcinoma (BCC) who will be receiving Photodynamic Therapy (PDT) as treatment for their tumors. This study wants to establish the optimal conditions for treating BCC tumors with PDT. Previous research suggests that taking Vitamin D prior to the start of PDT could help improve the effectiveness of the treatment in eliminating the BCC. Overall, this study will help establish oral Vitamin D3/PDT as a new combination therapy for skin cancer (BCC).
Photodynamic Therapy (PDT) is an investigational (experimental) technique that works by combining a photosensitizing topical agent and an intense light source to kill tumor cells. PDT is currently approved for the treatment of BCC in Europe, Canada, and Australia. However, it is experimental in the United States because it is not approved by the Food and Drug Administration (FDA).

Detailed Description
The overall hypothesis is that PDT could provide exceptional benefit in patients with Basal Cell Nevus Syndrome (BCNS) and multiple BCC tumors because PDT is nonmutagenic, nonscarring, and can be safely repeated many times. The specific study hypothesis is that Vitamin D might be useful as a neoadjuvant to improve tumor responses to PDT. In preclinical studies, the investigators showed that epithelial tumors are more responsive to aminolevulinic acid (ALA)-based PDT when "primed" by pre-exposure to the dietary form of Vitamin D (cholecalciferol, D3). This study will test the hypothesis that oral D3 supplements, administered over a relatively short time, can boost the effectiveness of PDT for cutaneous (BCC) in this patient population. Patients with BCNS and multiple BCC, or normal patients with at least 3 BCC tumors, will be enrolled. They will receive three PDT treatments, at two-month intervals, over a 6 month period.
Primary Objective
• To determine tumor clinical clearance rates after neoadjuvant D3/PDT, and after PDT alone. To accomplish this, the first two PDT treatments in each study patient will be randomized, i.e. one PDT session will be performed after D3 pretreatment, the other without any pretreatment.
Secondary Objective(s)
- To assess the level of PpIX accumulation in BCC lesions at various treatment visits, in the absence or presence of neoadjuvant D3. (Fluorescence dosimetry measurements)
- To assess tolerability of the technique. (Pain scale measurements)
- To assess patient satisfaction with the technique. (Cosmetic result, and questionnaire)
- To assess D3 serum levels (in serum) and VDR status (in leukocyte DNA), and correlate these results to clinical outcomes.
Study Design:
In this clinical study, each patient will serve as his or her own control with respect to BCC tumor responsiveness to neoadjuvant D3 supplementation. The first two PDT treatments will be randomized. Thus, patients in Group A will take D3 pills prior to the first PDT treatment, and placebo pills prior to the second PDT treatment. For patients in Group B, the order is reversed. Total amounts of D3 supplementation given will be adjusted, based upon serum 25-hydroxy-D3 levels found at baseline. Patients with VD deficiency will take 14 days of neoadjuvant D3, vs. only 5 days if the initial VD level is normal.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Group A: D3 prior to first PDT
In both groups, one PDT session is preceded by neoadjuvant PDT while the other PDT session has no pretreatment. Group A will take dietary D3 pills prior to the first PDT treatment (day 1), and placebo pills prior to the second PDT treatment (at 2 months). Both Group A and Group B will take continuous serum D3 prior to the third PDT visit (Month 4). A final assessment of lesion clearance will be performed at 6 months |
The daily dose of D3 will always be 10,000 IU/day.
Total amounts of D3 supplementation given will be adjusted, based upon serum 25-hydroxy-D3 levels found at baseline.
Duration of pretreatment will be 14 days if the D3 level is < 31 ng/mL, and 5 days if the D3 level is > 31 ng/mL

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
BCC: Rate of tumor clearance
Time Frame: Up to 6 months after first treatment visit
|
Change in tumor diameter per month. For each participant, the investigators will analyze the difference in tumor clearance between treatments, one with neoadjuvant D3+PDT, the other with PDT alone, and the other with or without D3 in order to establish a D3 replete state. The order of the first two treatments is randomized in case the assumption of a linear tumor clearance rate is incorrect The statistical significance of the difference in Delta-T after D3+PDT versus the difference in Delta-T after PDT alone will be tested using ANOVA. |
