SummaryBackground Rosacea is currently diagnosed by consensus-defined primary and secondary features and managed by subtype. However, individual features (phenotypes) can span multiple subtypes, which has implications for clinical practice and research. Adopting a phenotype-led approach may facilitate patient-centred management. Objectives To advance clinical practice by obtaining international consensus to establish a phenotype-led rosacea diagnosis and classification scheme with global representation. Methods Seventeen dermatologists and three ophthalmologists used a modified Delphi approach to reach consensus on statements pertaining to critical aspects of rosacea diagnosis, classification and severity evaluation. All voting was electronic and blinded. Results Consensus was achieved for transitioning to a phenotype-based approach to rosacea diagnosis and classification. The following two features were independently considered diagnostic for rosacea: (i) persistent, centrofacial erythema associated with periodic intensification; and (ii) phymatous changes. Flushing, telangiectasia, inflammatory lesions and ocular manifestations were not considered to be individually diagnostic. The panel reached agreement on dimensions for phenotype severity measures and established the importance of assessing the patient burden of rosacea. Conclusions The panel recommended an approach for diagnosis and classification of rosacea based on disease phenotype.
BackgroundApremilast, an oral, small‐molecule phosphodiesterase 4 inhibitor, has demonstrated efficacy in patients with moderate‐to‐severe psoriasis.ObjectiveEvaluate efficacy and safety of apremilast vs. placebo in biologic‐naive patients with moderate‐to‐severe plaque psoriasis and safety of switching from etanercept to apremilast in a phase IIIb, randomized, double‐blind, placebo‐controlled study (NCT01690299).MethodsTwo hundred and fifty patients were randomized to placebo (n = 84), apremilast 30 mg BID (n = 83) or etanercept 50 mg QW (n = 83) through Week 16; thereafter, all patients continued or switched to apremilast through Week 104. The primary efficacy endpoint was achievement of PASI‐75 at Week 16 with apremilast vs. placebo. Secondary endpoints included achievement of PASI‐75 at Week 16 with etanercept vs. placebo and improvements in other clinical endpoints vs. placebo at Week 16. Outcomes were assessed through Week 52. This study was not designed for apremilast vs. etanercept comparisons.ResultsAt Week 16, PASI‐75 achievement was greater with apremilast (39.8%) vs. placebo (11.9%; P < 0.0001); 48.2% of patients achieved PASI‐75 with etanercept (P < 0.0001 vs. placebo). PASI‐75 response was maintained in 47.3% (apremilast/apremilast), 49.4% (etanercept/apremilast) and 47.9% (placebo/apremilast) of patients at Week 52. Most common adverse events (≥5%) with apremilast, including nausea, diarrhoea, upper respiratory tract infection, nasopharyngitis, tension headache and headache, were mild or moderate in severity; diarrhoea and nausea generally resolved in the first month. No new safety or tolerability issues were observed through Week 52 with apremilast.ConclusionApremilast demonstrated significant efficacy vs. placebo at Week 16 in biologic‐naive patients with psoriasis, which was sustained over 52 weeks, and demonstrated safety consistent with the known safety profile of apremilast. Switching from etanercept to apremilast did not result in any new or clinically significant safety findings, and efficacy was maintained with apremilast through Week 52.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
