For decades, topical corticosteroids have been the mainstay of treatment for mild-to-moderate inflammatory skin diseases, even though only short-term use is approved for these agents and systemic inflammation is not addressed. Increased understanding of the immunopathogenesis of these conditions, especially for psoriasis and atopic dermatitis, has facilitated the development of antibody-based drugs that neutralize single key cytokines or their associated receptors, such as interleukin (IL)-17A/F, IL-23, and IL-17RA in psoriasis and IL-13 and IL-4Rα in atopic dermatitis. However, oral therapy is still preferred by many patients owing to the ease of use and needle-free administration. Phosphodiesterase 4 (PDE4) inhibitors have been approved for both oral and topical use for inflammatory skin diseases. In this review, we present a summary of an emerging class of selective PDE4B/D inhibitors under clinical development and compare the differences in selectivity of this new generation of PDE4 inhibitors with the less selective currently approved PDE4 inhibitors.

Introduction: Patients with moderate-to-severe plaque psoriasis who experience poor clinical outcomes, including patients with obesity or prior treatment, need improved treatment options. Risankizumab specifically inhibits interleukin 23 and has demonstrated superior efficacy in active-comparator studies in patients with moderate-to-severe plaque psoriasis. We compared the efficacy of risankizumab with that of secukinumab across patient subgroups. Methods: Subgroup analyses using data from the phase 3 IMMerge study (NCT03478787) were performed. Efficacy in adults with moderate-to-severe psoriasis treated with risankizumab 150 mg and secukinumab 300 mg was assessed as the proportion of patients who achieved ≥ 90% improvement in Psoriasis Area Severity Index (PASI 90) at week 52 across demographics and disease characteristics. Post hoc analyses evaluated the proportion of patients who achieved PASI 90 and the least-squares mean percent PASI improvement from baseline at week 52 by body weight and body mass index (BMI), PASI 90 by prior treatment, and clinical response [PASI 90, PASI 100, and/or static Physician's Global Assessment (sPGA) score of clear (0) or almost clear (1)] at week 16 and maintained particular response at week 52. Logistic regression analyses examined the effect of covariates (age, sex, BMI, baseline PASI, treatment) and potential interactions on PASI 90 at week 52. Results: More patients who received risankizumab (n = 164) compared with secukinumab (n = 163) achieved PASI 90 at week 52, regardless of demographics and disease characteristics (BMI, prior treatment, disease duration, and maintenance of clinical response at week 52). Improvements in PASI were greater in patients taking risankizumab than those taking secukinumab, regardless of weight or BMI. Results from logistic regression analysis showed treatment type had a significant impact on PASI 90 (risankizumab versus secukinumab, p < 0.0001). Conclusion: Risankizumab showed consistently greater efficacy compared with secukinumab across different patient subgroups, and this was maintained through 52 weeks. Trial Registration: ClinicalTrials.gov identifier; NCT03478787. Plain Language Summary: Patients with moderate-to-severe plaque psoriasis are often unable to achieve treatment success with currently available biologic therapies when they have other conditions, such as obesity, or have previous biologic therapy exposure and/or failure. We studied patients in the IMMerge phase 3 clinical trial (NCT03478787) to assess the efficacy of risankizumab compared with secukinumab for the treatment of plaque psoriasis and to determine risankizumab's ability to remain effective after 52 weeks of administration. In our analysis, we looked across patient subgroups including patient body weight, body mass index, previous use of biologic therapies, length of time patients had been living with their disease, and the durability of risankizumab efficacy at 52 weeks. Results from our analysis showed that patients had greater success with risankizumab compared with secukinumab in treating their plaque psoriasis, despite their age, sex, race, and disease characteristics, and that risankizumab remained effective in treating plaque psoriasis at week 52. Previously reported safety results from the IMMerge clinical trial showed that there were no new concerns regarding side effects for either risankizumab or secukinumab. Overall, these results support the use of risankizumab to treat patients, including those who have other conditions or may not have had success with other therapies in treating their plaque psoriasis.

Introduction: Since the 2012 Multinational Assessment of Psoriasis and Psoriatic Arthritis (MAPP) survey, several systemic treatments for psoriasis (PsO) and/or psoriatic arthritis (PsA) have been approved. The population-based UPLIFT survey was conducted to understand how perceptions of treatment-related outcomes have evolved, particularly for patients with mild to moderate PsO and/or PsA and their dermatologists. Methods: This population- and web-based survey was conducted from 2 March to 3 June 2020, in North America, Europe, and Japan. Adults with self-reported healthcare practitioner (HCP)-diagnosed PsO and/or PsA and dermatologists who spent > 50% of time treating patients and treated ≥ 20 patients with PsO, including plaque PsO, per month were included. Patient participants were recruited at random from online panels; dermatologists were recruited randomly from representative physician panels. Results: Of 264,054 patient responses, 3806 who self-reported an HCP diagnosis of PsO and/or PsA were included in the final sample; 67% had PsO alone, 28% had PsO and PsA, and 5% had PsA alone. The estimated population prevalence of psoriatic disease was 7% (PsO only: 4%; PsO and PsA: 2%; PsA only: 1%). Most patients (78%) reported PsO-involved body surface area (BSA) ≤ 3 palms, and ~ 90% or more reported itching, redness, flaking, and scales. Many PsO patients without diagnosed PsA reported musculoskeletal symptoms suggestive of PsA (63%). Across BSA categories, approximately one in four patients was not currently receiving treatment and > 50% had Dermatology Life Quality Index score > 5. Patients and dermatologists had different perceptions of PsO severity, office visit discussions, treatment goals, and treatment satisfaction. The survey was conducted during the coronavirus disease 2019 (COVID-19) pandemic, which could have affected assessments of patient-reported outcomes and ability to have in-person HCP visits. Conclusions: Patients with PsO and PsA in UPLIFT reported high disease burden, including patients with limited skin involvement. An opportunity exists to align patient and dermatologist perceptions to optimize management of PsO and PsA.

Plain Language Summary: In recent years, several new treatments for psoriasis and psoriatic arthritis have become available. The UPLIFT survey was conducted to understand how viewpoints on psoriatic disease outcomes have changed, especially for patients whose disease is mild or moderate. UPLIFT was a large, online, population-based survey conducted in North America, Europe, and Japan. Adults with psoriasis and/or psoriatic arthritis and dermatologists who treated at least 20 patients with psoriasis per month were included. There were 3806 patients who participated; of these, most had psoriasis and few had psoriatic arthritis. Most patients (78%) with mild to moderate psoriasis had a limited area of skin affected by psoriasis. Psoriasis symptoms were common and included itching, redness, flaking, and scales. Many patients without a diagnosis of psoriatic arthritis reported symptoms that could be related to this disease (such as joint discomfort). Although many patients had psoriasis symptoms, approximately one in four was not currently receiving treatment and more than half reported psoriasis impacted their quality of life. Patients and dermatologists had different perceptions of psoriasis severity, office visit discussions, treatment goals, and treatment satisfaction. There is an opportunity to improve treatment of psoriasis and psoriatic arthritis and to better align patient and physician perceptions of psoriasis. This survey was conducted during the COVID-19 pandemic, which could have partially affected some assessments and the ability to have in-person doctor visits. [ABSTRACT FROM AUTHOR]
