Efficacy and safety of oral roflumilast for moderate-to-severe psoriasis-a randomized controlled trial (PSORRO).

ABSTRACT:

Background

Roflumilast is a targeted inhibitor of phosphodiesterase (PDE)-4 and has been approved for treatment of severe chronic obstructive pulmonary disease for more than a decade. Generic versions are available in the United States. PDE-4 is involved in the psoriasis pathogenesis, but the efficacy and safety of oral roflumilast in patients with psoriasis have not previously been studied.

Methods

A company-independent, multicenter, randomized, double-blind, placebo-controlled trial (ClinicalTrials.govNCT04549870). Patients were randomized 1:1 to receive monotherapy with oral roflumilast 500 μg once daily or placebo. At week 12, placebo patients were switched to open-label roflumilast through week 24. The primary endpoint was a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI75) at week 12.

Findings

In all, 46 patients were randomized (roflumilast, n = 23; placebo, n = 23). At week 12, significantly more patients in the active arm achieved PASI75 (8 of 23 patients [35%]) vs. placebo (0 of 23 patients [0%], with a difference vs. placebo of 8 [35%] patients, 95% CI: 3 [13%]-13 [57%] patients) (p = 0.014). At week 24, 15 (65%), 10 (44%), 5 (22%), and 2 (9%) of patients treated with roflumilast from week 0 had PASI50, PASI75, PASI90, and PASI100 responses (key secondary endpoints), respectively. The most prevalent, drug-related adverse events in both treatment groups were transient gastrointestinal symptoms, weight-loss, headache, and insomnia. A total of three patients (roflumilast n = 2; placebo, n = 1) discontinued therapy due to adverse events.

Interpretation

Oral roflumilast was efficacious and safe in treating moderate-to-severe plaque psoriasis over 24 weeks. With generic versions available, this drug may represent an inexpensive and convenient alternative to established systemic psoriasis treatments.

Funding

Financial support was received from Herlev and Gentofte Hospital, University of Copenhagen, and independent grants from private foundations in Denmark. No pharmaceutical company, including the market authorization holder of roflumilast, was involved in the study at any point.

Project description:Background and objectivePlaque psoriasis is commonly treated topically with glucocorticoids and vitamin D derivatives. However, potential side effects such as skin atrophy underscore the need for safe and effective alternative topical therapies. Recently, the US Food and Drug Administration (FDA) and Health Canada approved roflumilast 0.3% cream as an option for treating this disease. A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to assess the efficacy and safety of topical roflumilast 0.3% compared with vehicle for plaque psoriasis.MethodsPubMed, Embase, ClinicalTrials.gov, and Cochrane databases were searched from inception to 1 May 2024, assessing the outcomes of Investigator's Global Assessment (IGA) or body-IGA success (clear or almost clear status plus an at least 2-grade improvement from baseline), Psoriasis Area and Severity Index (PASI)-50, PASI-75, PASI-90, intertriginous-IGA success (clear or almost clear status on the intertriginous-IGA plus an at least 2-grade improvement from baseline), and adverse events (AEs). Statistical analysis was performed using Review Manager, R software, and RStudio. Heterogeneity was determined using the Cochran Q test and I2 statistics.ResultsFour RCTs were included, comprising a total of 1403 patients, of whom 885 (63.1%) received topical roflumilast 0.3% and 518 (36.9%) received vehicle. At week 8, the achievement of IGA or body-IGA success was significantly higher among those treated with topical roflumilast than in the vehicle group [relative risk (RR) 5.07; 95% confidence interval (CI) 3.55-7.23; p < 0.01]. Similar findings were observed at week 8 for PASI-50 (RR 2.73; 95% CI 2.27-3.29; p < 0.01), PASI-75 (RR 4.48; 95% CI 2.26-8.89; p < 0.01), and PASI-90 (RR 5.61; 95% CI 2.57-12.25; p < 0.01). Corresponding outcomes were found at weeks 2, 4, and 6. Additionally, a higher percentage of patients treated with topical roflumilast 0.3% once daily achieved intertriginous-IGA success, compared with those receiving vehicle, at week 8 (71.9% versus 20.5%; RR 3.32; 95% CI 2.11-5.22; p < 0.01), with similar findings at weeks 2, 4, and 6. While a significant difference was observed in the overall incidence of AEs between the topical roflumilast and vehicle groups, there was no difference in treatment-related AEs, serious AEs, or AEs leading to study discontinuation.ConclusionThese findings support the superiority of topical roflumilast 0.3% over vehicle and suggest its use as a valuable asset for the treatment of plaque psoriasis.Protocol registrationInternational Prospective Register of Systematic Reviews (PROSPERO), CRD42023456494.

Project description:BackgroundPsoriasis is a chronic immune-mediated inflammatory skin disease affecting both adults and children. To better understand the efficacy-safety profile of biologics in children with moderate-to-severe psoriasis, this study aimed to analyze efficacy and safety data of randomized controlled trials (RCTs) performed in pediatric psoriasis and to compare efficacy outcomes in children with those in adults.MethodsRCTs investigating biologics in children with moderate-to-severe psoriasis were identified in a systematic literature review. PASI75/90 treatment responses at weeks 11/12 were analyzed comparing biologics with control arms. Serious adverse events (SAEs) were analyzed at the end of each study. Efficacy data from RCTs in adults with psoriasis were selected for the same biologics. Risk ratios (RR) of selected RCTs were pooled together in a statistical random effects model using the inverse variance method.ResultsFor children, there were 1 etanercept, 2 secukinumab, 1 ixekizumab and 1 ustekinumab placebo-controlled RCTs and 1 adalimumab RCT using methotrexate as reference arm at weeks 11/12. For adults, out of 263 RCTs, 7 adalimumab and 15 etanercept (TNF inhibitors) and 4 ixekizumab and 12 ustekinumab (IL-17 and IL-12/23 inhibitors) RCTs reported PASI75/90 efficacy responses at weeks 11/12. Regarding efficacy, all biologics showed improved PASI responses over control arms. RRs ranges were 2.02-7.45 in PASI75 and 4.10-14.50 in PASI90. The highest PASI75 responses were seen for ustekinumab 0.375 mg/kg (RR = 7.25, 95% CI 2.83-18.58) and ustekinumab 0.75 mg/kg (RR = 7.45, 95% CI 2.91-19.06) in the CADMUS study. The highest PASI90 response was seen for ixekizumab (RR = 14.50, 95% CI 4.82-43.58) in the IXORA-PEDS study. SAE incidences in pediatric and adult arms with biologics were 0 to 3% except for a pediatric arm with adalimumab 0.40 mg/kg (8%). For adults, pooled RR also showed improved PASI responses over placebo for all biologics, with highest PASI75 response observed for ixekizumab (pooled RR = 16.18, 95% CI 11.83-22.14).ConclusionBoth adults and children with psoriasis show superior efficacy with biologics compared to control arms after 3 months of treatment with SAE incidences in the low percentages. Additional longer-term clinical studies are warranted to fully understand the overall efficacy-safety profile of biologics in children with moderate-to-severe psoriasis.

Project description:Activation of Sirtuin (silent mating type information regulation 2 homolog) 1, or SIRT1, is an unexplored therapeutic approach for treatment of inflammatory diseases. The goal of this study was to evaluate the clinical activity and tolerability of multiple doses of SRT2104, a selective activator of SIRT1, in patients with moderate to severe psoriasis after day 84 of treatment. Forty patients were randomized 4:1 to three escalating doses of SRT2104 (250, 500, 1000 mg/d SRT2104 or placebo). Across all SRT2104 groups, 34.6% of patients (9 out of 26; 90% CI 18.0%-54.2%, p<0.0001) achieved good to excellent histological improvement based on skin biopsies taken at baseline and day 84. To evaluate the changes in expression profile with treatment and to identify pathways involved in histological improvement, a subset of 22 Pre and Post treatment biopsies from 11 patients (4 Placebo, 7 Active Treatment) were hybridized to hgu133plus2 chips. Improvement in histology was associated with modulation of IL-17 and TNF-_ signaling pathways and keratinocyte differentiation target genes. Various studies suggest a crucial role of TNF_ and IL-17 in psoriasis pathogenesis and IL-17/TNF_ synergism induces a strong induction of differentially expressed genes in psoriasis, thus advocating a crucial role of IL-17/TNF_ combination in the molecular basis of disease (Chiricozzi et al., 2010). In the current study, broad scale gene expression profiling revealed that SRT2104 significantly reduced known IL-17 and TNF_ responsive genes including SERPINB4, S100A12, SERPINB3, kynu etc. even though the sample size for this analysis was small. One of the most highly modulated genes by SRT2104 included Kynu, a gene that regulates tryptophan metabolism, known to confer antibacterial effector functions (Daubener and MacKenzie, 1999). Interestingly kynu is part of the etanercept residual genomic profile that is not modulated by etanercept therapy even though clinical efficacy is achieved. Possibly, SRT2104 may be modulating the lipid barrier of the epidermis of psoriatic skin via modulation of keratinocyte diferentiation genes, which would be consistent with the observed improvement in skin histology. These results indicate a combinatorial effect of SRT2104 on TNF_, and IL-17 inflammatory signaling pathways and keratinocyte differentiation that could be a contributing factor towards improvement in clinical scores by the SIRT1 activator, SRT2104. Paired Pre (Day 1) and Post (Day 84) Treatment samples were obtained from 4 Placebo Patients and 7 patients treated with SRT2104 at 3 different doses (250, 500, 1000 mg).

Project description:TitleSecukinumab efficacy and safety in Indian patients with moderate-to-severe plaque psoriasis: sub-analysis from FIXTURE (Full Year Investigative Examination of Secukinumab vs. Etanercept Using Two Dosing Regimens to Determine Efficacy in Psoriasis), a randomized, placebo-controlled, phase 3 study.BackgroundEvidence has suggested Interleukin (IL)-17A to be an important effector cytokine in the pathogenesis of psoriasis. Here, we report results for an Indian sub-population from a multinational study FIXTURE, designed to assess the safety, tolerability, and long-term efficacy of fully human anti-IL-17A monoclonal antibody secukinumab in patients with moderate-to-severe plaque psoriasis.Materials and methodsIn this double-dummy, placebo controlled, 52-weeks phase 3 study FIXTURE, 149 Indian patients were randomized 1:1:1:1 to receive secukinumab at a dose of 300 mg or 150 mg, etanercept, or placebo. The study objective was to show the superiority of secukinumab over placebo at week 12, vis-à-vis proportion of patients achieving a reduction of 75% or more from the baseline in the psoriasis area-and-severity index score (PASI 75) and a score of 0 (clear) or 1 (almost clear) on a 5-point modified investigator's global assessment (IGA mod 2011) (co-primary end points).ResultsAt week 12, 61.0% and 55.9% patients in secukinumab 300 mg and 150 mg groups, respectively, achieved PASI 75 response compared to 20.0% in the etanercept and 7.1% in the placebo groups. Similarly, IGA mod 2011 0 or 1 response was achieved by 43.9% and 20.6% in patients in the secukinumab 300 mg and 150 mg group, respectively, vs. 13.3% in the etanercept and 2.4% in the placebo groups at week 12. Likewise, higher proportions of patients in secukinumab 300 mg (41.5%) and 150 mg (20.6%) group were PASI 90 responders at week 12 than those in the etanercept (10.0%) or placebo (0.0%) groups. The incidences of adverse events (AEs), during the induction period were similar in all the treatment groups. Overall secukinumab was well-tolerated at both doses in the Indian sub-population.ConclusionThe results from the Indian sub-population suggest that secukinumab is an efficacious and safe drug for use in moderate-to-severe chronic plaque psoriasis.
