BF-200 ALA is a very effective, well-tolerated new formulation for AK treatment with PDT and is superior to a registered MAL medication. Efficacies and adverse events vary greatly with the different light sources used.

Objective. To describe a group of patients who were treated with tumor necrosis factor ␣ (TNF␣) antagonists and who developed coccidioidomycosis, and to test the hypothesis that patients with inflammatory arthritis receiving TNF␣ antagonist therapy are at higher risk for developing symptomatic coccidioidomycosis.Methods Conclusion. Patients with inflammatory arthritis who are undergoing treatment with infliximab appear to be at higher risk for developing symptomatic coccidioidomycosis as compared with those not receiving infliximab.

BackgroundTwo phase III trials of photodynamic therapy (PDT) with BF-200 ALA, a recently approved nanoemulsion formulation of 5-aminolaevulinic acid (ALA) demonstrated high clearance rates in mild-to-moderate actinic keratosis (AK). The comparison to a registered methyl aminolaevulinate (MAL) cream demonstrated significantly superior total patient clearance rates.ObjectivesTo evaluate long-term efficacy and safety of PDT for AK 6 and 12 months after the last PDT with BF-200 ALA, MAL or placebo.MethodsThe follow-up phase (FUP) was performed with patients of two phase III studies. Both studies compared BF-200 ALA with placebo, one of the studies additionally with MAL. Overall recurrence rates and various subgroups (light source, lesion severity, lesion location, complete responders after first PDT) were assessed 6 and 12 months after the last PDT.ResultsRecurrence rates were similar for BF-200 ALA and MAL, with a tendency to lower recurrence rates for BF-200 ALA. The proportion of patients who were fully cleared during PDT and remained completely clear for at least 12 months after PDT were 47% for BF-200 ALA (both studies) and 36% for MAL treatment. The subgroup that was illuminated with narrow wavelength LED lamps reached 69% and 53% for BF-200 ALA (both studies, respectively) and 41% for MAL. No safety concerns were reported.ConclusionsThe FUP data confirmed the high efficacy and safety of PDT with BF-200 ALA. The slightly lower recurrence rates after BF-200 ALA treatment compared with MAL treatment enhanced the better treatment outcome due to the significantly superior efficacy.

A prospective randomized exploratory study comparing the efficacy of once-daily topical 0.5% 5-fluorouracil in combination with 10.0% salicylic acid (5-FU/SA) vs. cryosurgery for the treatment of hyperkeratotic actinic keratosis Mean change in lesion count from baseline to Day 98 was À5.2 and À5.7 lesions per patient for 0.5% 5-FU/SA and cryotherapy groups respectively. Histological AK clearance rates on Day 98 were 62.1% and 41.9% respectively. At 6-month posttreatment follow-up, recurrence of cleared lesions (no clinically visible lesions in treatment area) occurred in 39.4% of 0.5% 5-FU/SA and 84.8% of cryosurgery patients. Drug-related adverse events (AEs), including local skin reactions considered 'severe' by the investigator, were reported in 24.2% of 0.5% 5-FU/SA and 6.1% of cryosurgery patients. All drug-related AEs were skin reactions.Conclusions Although the study was not powered to explore statistical differences in clinical efficacy between treatments, a short (6-week) schedule of topical treatment with 0.5% 5-FU/SA achieved greater histological clearance and lower recurrence of grade II/III hyperkeratotic AKs than cryosurgery. AE incidence across both treatment groups was relatively low and AEs were generally mild or moderate. Clinical trials.gov identifier: NCT01358851.
