Background:
Mild-moderate psoriasis vulgaris is a common dermatological autoimmune condition with limited conventional therapeutic options. Safe and effective adjunct therapies to topical non-steroidal antipsoriatic therapy are needed. The oral Chinese herbal medicine (CHM) formula PSORI-CM01 has been evidenced potential antipsoriatic pharmacological activity. This article reports a pilot study which was designed as a double-blinded, placebo-controlled randomized controlled trial (RCT) evaluating the effects of PSORI-CM01 when added to topical calcipotriol cream.
Methods:
People with moderate psoriasis vulgaris were randomized to receive oral PSORI-CM01 or placebo administered for 12 weeks in combination with calcipotriol. The primary clinical outcome was the change of psoriasis area severity index (PASI) score at week 12 and week 24. Secondary clinical outcomes were PASI75, PASI50, relapse rate, change in body surface area, dermatology life quality index and Skindex29, and adverse events (AEs). Participants' satisfaction and willingness to repeat were also assessed.
Results:
The pilot study was conducted in Australia and China, 29 participants were randomized with 26 completed the treatment and follow-up. Participants' baseline basic characteristics were comparable. No between-group statistical significance was found on pre-defined clinical outcome measures, although there seemed a trend of treatment effects favoring the combination of PSORI-CM01 with calcipotriol. Frequency and severity of AEs were similar between two groups, with no severe AEs reported.
Conclusions:
The design and duration of the study appears feasible. A proper powered RCT with slight adjustments in the methods is needed to reveal the add-on effects of oral CHM PSORI-CM01. The experience and results from this pilot study will contribute to the refine of objectives and design of a future study, and assist the sample size calculation for the full-scale RCT.
