This study evaluated the toxicity and efficacy of topical topitriol (calcitriol, 1,25-dihydroxyvitamin D3) to prevent chemotherapy-induced alopecia (CIA). Patients with breast cancer scheduled to receive FAC chemotherapy (5-fluorouracil, adriamycin and cyclophosphamide) were eligible for the study. Initially, the first six patients were randomized in a double-blind fashion to have received topitriol or placebo with all subsequent patients being treated with topitriol. Topitriol cream (0.0025 or 0.005%; 25 and 50 microg/g concentration) was administered topically twice a day. Three different doses and schedules of administration were evaluated including: 500 and 1000 microg daily for 7 days prior to chemotherapy, and 2000 microg daily for 5 days prior and 5 days post-chemotherapy. Fourteen patients were treated (12 with topitriol and two with placebo) at three different dose levels. All patients developed grade 2 alopecia between day 20 and 30 after chemotherapy, demonstrating the lack of efficacy of topical topitriol on this schedule of administration to prevent CIA. Eight patients exposed to topitriol developed a toxic maculopapular dermatitis in areas exposed to the drug. In conclusion, topical topitriol at the doses and schedules evaluated in this trial was ineffective to prevent CIA and induced a local dermatitis in areas exposed to the drug.
