Abstract
Introduction: Topical therapies are used in almost all patients with psoriasis. A novel fixed topical combination cream (GN-037) with a lower concentration (0.0356%) of clobetasol 17-propionate (CP) was developed together with urea, salicylic acid, and retinoic acid to provide a better benefit-risk ratio. The present multicenter randomized double-blind vehicle-controlled parallel group phase 2 study aimed to investigate the efficacy and safety of GN-037 in patients with mild-to-moderate plaque psoriasis (MMPP).
Methods: Patients (n = 190) were randomized (2:2:1) to receive GN-037 or CP or vehicle (V) cream twice daily to a selected target body lesion for 4 weeks. The primary endpoint was treatment success defined as percentage of patients with at least two-grade improvement in Investigator's Global Assessment Score (IGA) and IGA score equal to 0 or 1 evaluated at weeks 2, 4, 6, and 8 in each arm compared with baseline. Treatment-emergent adverse events (TEAEs) and safety were evaluated throughout the study.
Results: GN-037 demonstrated statistically significant superiority over V throughout the study. At week 4, treatment success was achieved in 37.9% of patients in the GN-037 arm compared with 29.2% and 9.1% in the CP and V arms, respectively. At least two-grade improvement compared with baseline was achieved by 57.6%, 72.7%, and 80.3% of the patients in the GN-037 arm for erythema, plaque elevation, and scaling, respectively. The mean changes in affected BSA were -2.1 ± 2.9, -1.8 ± 2.4, and -0.5 ± 1.6 in the GN-037, CP, and V arms, respectively. The TEAEs were similar among the arms and the most frequently observed TEAEs were Psoriasis Area and Severity Index (PASI) increase in all arms.
Conclusions: GN-037 was more effective than V in achieving primary and all secondary endpoints throughout the study. Safety data did not reveal any new safety concerns with the combination cream product. Therefore, 4 weeks of GN-037 treatment demonstrated an excellent efficacy and safety profile in patients with MMPP.
期刊介绍：
Dermatology and Therapy is an international, open access, peer-reviewed, rapid publication journal (peer review in 2 weeks, published 3–4 weeks from acceptance). The journal is dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of dermatological therapies. Studies relating to diagnosis, pharmacoeconomics, public health and epidemiology, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to all clinical aspects of dermatology, such as skin pharmacology; skin development and aging; prevention, diagnosis, and management of skin disorders and melanomas; research into dermal structures and pathology; and all areas of aesthetic dermatology, including skin maintenance, dermatological surgery, and lasers.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols, and short communications. Dermatology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an International and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. The journal appeals to a global audience and receives submissions from all over the world.
