Mild to moderate psoriasis is highly prevalent in about 80% of the global psoriatic population. Current available treatment options for mild to moderate psoriasis are topical dosage forms and are associated variety of setbacks. To address these setbacks, Apremilast topical gels, 2% & 4%, w/w were developed, and a clinical proof of concept study (POC) was performed to establish efficacy and safety. A single centre randomized, double-blind, placebo-controlled study was conducted with apremilast topical gels 2% & 4% w/w in adult mild to moderate psoriatic patients for 12 weeks. The efficacy of the gels was evaluated by comparing the PASI scores before and after treatment of 12 weeks. Both gels exhibited a significant reduction in PASI values when compared with baseline PASI scores. An average percentage inhibition of PASI with test products, i.e. 2% and 4% w/w Apremilast topical gels, are about 46.8% and 34.6%, respectively, after 12 weeks of treatment. The results confirm that the apremilast topical gels are a good option for the treatment of mild to moderate psoriasis and have to be explored further.
