Introduction: Treatment adherence continues to be a major challenge in psoriasis. Patient preference studies, especially discrete-choice experiments, are gaining popularity to gather insights into patient reported treatment outcomes. This systematic literature review aimed to critically assess all discrete choice experiments exploring patients' and physicians' preferences for psoriasis treatment characteristics. ⋯ Factors such as age, disease severity, and duration of condition significantly affected preferences for treatment attributes. Conclusions: This review provides insight into the types of attributes that patients and physicians value most, and therefore can help improve shared decision-making. The findings of this study also encourage regulatory agencies to continue integrating patient preferences in their decision-making.

Objective: Autoinjectors are a convenient and efficient way to self-administer subcutaneous injections of biopharmaceuticals. Differences in device mechanical design can affect the autoinjector functionality and performance. This study investigates the performance differences of two single-spring-actuated autoinjectors. ⋯ Lastly, confirmation "click" sound of Emgality occurs 0.75-1.53 s after dose completion, while in Aimovig, the confirmation "click" sound occurs 0.26-0.46 s before dose completion. Conclusions: This study revealed performance differences between Emgality and Aimovig autoinjector devices, despite the fact that the delivery principle of these single-spring-actuated autoinjectors are the same. These differences may result in different risk of intramuscular injection and premature device removal, both of which need to be further verified in clinical trials.

Randomized Controlled Trial
Efficacy and safety of ertugliflozin across racial groups in patients with type 2 diabetes mellitus.
Objective: To assess the efficacy and safety of the sodium-glucose cotransporter 2 inhibitor ertugliflozin across racial groups in patients with type 2 diabetes mellitus (T2DM). Methods: Pooled analysis of data from randomized, double-blind studies in the ertugliflozin phase III development program. Seven placebo- and comparator-controlled studies were used to assess safety (N = 4859) and three placebo-controlled studies were used to assess efficacy (N = 1544). ⋯ Conclusions: In patients with T2DM, treatment with ertugliflozin improved HbA1c, body weight and SBP across all racial subgroups. Ertugliflozin had a generally similar safety profile across racial subgroups and was generally well tolerated. Clinicaltrials.gov identifiers: NCT01986855, NCT01999218, NCT01958671, NCT02099110, NCT02036515, NCT02033889, and NCT02226003.

Background: In the United States, the number of new cases of hepatitis C virus infection has risen in recent years, driven largely by transmission among young white adults in their 20s and 30s. Herein, we report an integrated analysis of participants with hepatitis C virus infection aged ≤35 years from 12 phase II/III clinical trials of elbasvir/grazoprevir. Methods: Treatment-naive and -experienced adults with hepatitis C virus genotype 1 or 4 infection received elbasvir (50 mg/day)/grazoprevir (100 mg/day) for 12 weeks without ribavirin. ⋯ Safety was favorable, with the incidence of drug-related adverse events similar in younger and older participants (30.1% vs 30.6%). One participant (0.4%) aged ≤35 years and 15 participants (0.7%) aged >35 years discontinued treatment owing to adverse events. Conclusions: Elbasvir/grazoprevir for 12 weeks was safe and highly effective in participants aged ≤35 years with hepatitis C virus genotype 1 or 4 infection.
