ImportanceLebrikizumab (LEB), a high-affinity monoclonal antibody targeting interleukin (IL)-13, demonstrated efficacy and safety in patients with moderate-to-severe atopic dermatitis (AD) during 16 weeks of monotherapy in a phase 2b trial, and two 52-week phase 3 trials.ObjectiveTo evaluate efficacy and safety of LEB combined with low- to mid-potency topical corticosteroids (TCS) in patients with moderate-to-severe AD.Design, Setting, and ParticipantsThe ADhere trial was a 16-week randomized, double-blinded, placebo (PBO)-controlled, multicenter, phase 3 clinical trial conducted from February 3, 2020, to September 16, 2021. The study was conducted at 54 outpatient sites across Germany, Poland, Canada, and the US and included adolescent (aged ≥12 to <18 years weighing ≥40 kg) and adult patients with moderate-to-severe AD. The treatment allocation ratio was 2:1 (LEB:PBO).InterventionsOverall, 211 patients were randomized to subcutaneous LEB (loading dose of 500 mg at baseline and week 2, followed by 250 mg every 2 weeks [Q2W] thereafter) or PBO Q2W in combination with TCS for 16 weeks.Main Outcomes and MeasuresEfficacy analyses at week 16 included proportions of patients achieving Investigator’s Global Assessment score of 0 or 1 (IGA [0,1]) with 2 or more points improvement from baseline, and 75% improvement in the Eczema Area and Severity Index (EASI-75). Key secondary end points included evaluation of itch, itch interference on sleep, and quality of life. Safety assessments included monitoring adverse events (AEs).ResultsThe mean (SD) age of patients was 37.2 (19.3) years, 103 (48.8%) patients were women, 31 (14.7%) patients were Asian, and 28 (13.3%) patients were Black/African American. At week 16, IGA (0,1) was achieved by 145 (41.2%) patients in the LEB+TCS group vs 66 (22.1%) receiving PBO+TCS (P = .01); corresponding proportions of patients achieving EASI-75 were 69.5% vs 42.2% (P < .001). The LEB+TCS group showed statistically significant improvements in all key secondary end points. Most treatment-emergent adverse events (TEAEs) were nonserious, mild or moderate in severity, and did not lead to study discontinuation. The TEAEs frequently reported in the LEB+TCS group included conjunctivitis (7 [4.8%]), headache (7 [4.8%]), hypertension (4 [2.8%]), injection site reactions (4 [2.8%]), and herpes infection (5 [3.4%]) vs 1.5% or less patient-reported frequencies in the PBO+TCS group. Similar frequencies of patient-reported serious AEs following LEB+TCS (n = 2, 1.4%) and PBO+TCS (n = 1, 1.5%).Conclusions and RelevanceIn this randomized phase 3 clinical trial, LEB+TCS was associated with improved outcomes in adolescents and adults with moderate-to-severe AD compared with TCS alone, and safety was consistent with previously reported AD trials.Trial RegistrationClinicalTrials.gov Identifier: NCT04250337
Objectives: This study documents real-world patterns and additional costs of above-label (!10% above the recommended maintenance dose) use of biologics in patients with plaque psoriasis. Materials and methods: This was a descriptive, retrospective cohort analysis using the IBM MarketScan Commercial and Medicare Supplemental Databases. Adult patients diagnosed with plaque psoriasis initiating treatment with etanercept, adalimumab, ixekizumab, or secukinumab between 1 January 2015 and 30 November 2019 (index) were eligible. Only biologics approved prior to 2017 were included to ensure data for all agents was available throughout the study period. Patients had no other indications for biologics of interest. Outcomes were measured in the 12-month follow-up period after start of maintenance dosing. Results: Of 6453 patients included, 708 (11.0%) received etanercept, 4654 (72.1%) received adalimumab, 228 (3.5%) received ixekizumab, and 863 (13.4%) received secukinumab. Above-label dosing was recorded in 326 (46.0%) patients receiving etanercept, 513 (11.0%) receiving adalimumab, 40 (17.5%) receiving ixekizumab, and 79 (9.2%) receiving secukinumab. Mean time to above-label use for all treatments was 50.7-99.5 days; the median was 21-37 days. Mean duration of above-label use for all treatments was 130-196 days; the median was 35-175 days.
A 79-year-old male presented for removal of what was proven to be a keratoacanthoma. Additional tissue removed deep to the initial lesion revealed intravascular basal cell carcinoma (BCC). Intravascular BCC is exceedingly rare with only 8 cases previously reported in the literature. Intravascular BCC may be associated with more aggressive subtypes. Intravascular infiltration is more common in metastatic BCC, but this finding may not imply causality. More data are required in order to determine prognostic implications of intravascular BCC and to develop a protocol for managing patients with this unique finding.
Tumor necrosis factor alpha (TNFalpha) plays a key pathophysiological role in psoriasis and psoriatic arthritis (PsA). Recent interest has thus focused on the clinical potential of TNFalpha antagonists (e.g. etanercept) in these settings. In psoriasis, several large pooled analyses and well-designed clinical trials documented the significant clinical efficacy and generally favorable tolerability of etanercept for up to 96 weeks. Similarly, in PsA, a large phase III trial showed that, etanercept significantly reduced arthritic symptoms and inhibited radiographic disease progression; sustained clinical benefit was again evident for up to 2 years. Etanercept is at the forefront of psoriatic disease management, and continued evolution and evaluation of the compound - for example, in detailed comparative studies and economic analyses - is likely to confirm a key role for etanercept in the treatment of psoriasis and PsA.
