Ten-year safety and clinical benefit from open-label etanercept treatment in children and young adults with juvenile idiopathic arthritis.

OBJECTIVES: CLIPPER2 was an 8-year, open-label extension of the phase 3b, 2-year CLIPPER study on the safety and efficacy of etanercept in patients with JIA, categorized as extended oligoarticular arthritis (eoJIA), enthesitis-related arthritis (ERA) or PsA. METHODS: Participants with eoJIA (2-17 years old), ERA or PsA (each 12-17 years old) who received ≥1 etanercept dose (0.8 mg/kg weekly; maximum 50 mg) in CLIPPER could enter CLIPPER2. Primary end point was occurrence of malignancy. Efficacy assessments included proportions achieving JIA ACR 30/50/70/90/100 criteria and ACR inactive disease criteria, and clinical remission (ACR criteria) or Juvenile Arthritis DAS (JADAS) ≤1. RESULTS: Overall, 109/127 (86%) CLIPPER participants entered CLIPPER2 [n = 55 eoJIA, n = 31 ERA, n = 23 PsA; 99 (78%) on active treatment]; 84 (66%) completed 120 months' follow-up [32 (25%) on active treatment]. One malignancy (Hodgkin's disease in 18-year-old patient with eoJIA treated with methotrexate for 8 years) was reported; there were no cases of active tuberculosis or deaths. Numbers and incidence rates (events per 100 patient-years) of TEAEs (excluding infections/ISRs) decreased from 193 (173.81) in Year 1 to 9 (27.15) in Year 10; TE infections and serious infections also decreased. Over 45% of participants (n = 127) achieved JIA ACR50 responses from Month 2 onwards; 42 (33%) and 34 (27%) participants achieved JADAS and ACR clinical remission, respectively. CONCLUSIONS: Etanercept treatment up to 10 years was well tolerated, consistent with the known safety profile, with durable response in the participants still on active treatment. The benefit-risk assessment of etanercept in these JIA categories remains favourable. TRIAL REGISTRATION: ClinicalTrials.gov IDs: CLIPPER (NCT00962741); CLIPPER2 (NCT01421069).

Efficacy and safety of crisaborole ointment, 2%, in participants aged ≥45 years with stasis dermatitis: Results from a fully decentralized, randomized, proof-of-concept phase 2a study.

BACKGROUND: Crisaborole ointment, 2%, is a nonsteroidal topical phosphodiesterase 4 inhibitor approved for the treatment of mild-to-moderate atopic dermatitis. OBJECTIVE: To evaluate the efficacy and safety of crisaborole in stasis dermatitis (SD). METHODS: In this randomized, double-blind, vehicle-controlled, decentralized phase 2a study (NCT04091087), 65 participants aged ≥45 years with SD without active ulceration received crisaborole or vehicle (1:1) twice-daily for 6 weeks. The primary end point was percentage change from baseline in total sign score at week 6 based on in-person assessment. RESULTS: Crisaborole-treated participants had significantly reduced total sign score from baseline versus vehicle based on in-person (nondermatologist) assessment (-32.4% vs -18.1%, P = .0299) and central reader (dermatologists) assessment of photographs (-52.5% vs -10.3%, P = .0004). Efficacy according to success and improvement per Investigator's Global Assessment score and lesional percentage body surface area reached statistical significance based on central reader but not in-person assessments. Skin and subcutaneous tissue disorders were common all-causality treatment-emergent adverse events with crisaborole. LIMITATIONS: Small sample size and short treatment duration were key limitations. In-person assessment was not conducted by dermatologists. CONCLUSION: Crisaborole improved signs and symptoms of SD and was well tolerated. Central reader assessment represents a promising approach for siteless clinical research.

Crisaborole reverses dysregulation of the mild to moderate atopic dermatitis proteome toward nonlesional and normal skin.

BACKGROUND: Safe and effective long-term topical treatments for atopic dermatitis (AD) remain limited. OBJECTIVE: In this phase 2a, single-center, intrapatient, and vehicle-controlled study, we examine the mechanism of action of crisaborole 2% ointment, a topical nonsteroidal PDE4 (phosphodiesterase-4) inhibitor, in a proteomic analysis of 40 adults with mild to moderate AD and 20 healthy subjects. METHODS: Within the AD cohort, 2 target lesions were randomized in an intrapatient (1:1) manner to double-blind crisaborole/vehicle applied twice daily for 14 days. Punch biopsy specimens were collected for biomarker analysis at baseline from all participants, then from AD patients only at day 8 (optional) and day 15. RESULTS: Compared to the vehicle, crisaborole significantly reversed dysregulation of the overall lesional proteome and of key markers and pathways (eg, Th2, Th17/Th22, and T-cell activation) associated with AD pathogenesis toward both nonlesional and normal skin. Significant clinical correlations were observed with markers associated with nociception and Th2, Th17, and neutrophilic activation. LIMITATIONS: Study limitations include predominance of white patients in the cohort, relatively short treatment time, and regimented administration of crisaborole. CONCLUSION: Our results demonstrate crisaborole-induced normalization of the AD proteome toward a nonlesional molecular phenotype and further support topical PDE4 inhibition in the treatment of mild to moderate AD.

Correlation between burst suppression and postoperative delirium in elderly patients: a prospective study.

OBJECTIVE: To explore the correlation between intraoperative burst suppression (BS) and postoperative delirium (POD) in elderly patients, and provide more ideas for reducing POD in clinical. METHODS: Ninety patients, aged over 60 years, who underwent lumbar internal fixation surgery in our hospital were selected. General information of patients was obtained and informed consent was signed during preoperative visits. Patients were divided into burst suppression (BS) group and non-burst suppression (NBS) group by intraoperative electroencephalogram monitoring. Intraoperative systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were recorded, and the variation and minimum value were obtained by calculating. Hemoglobin (HGB), C-reactive protein (CRP), system immune inflammatory index (SII) at 24 and 72 h after surgery, the incidence of postoperative adverse reactions, postoperative hospital stay, and total cost were recorded after operation. POD assessment was performed using CAM within 7 days after surgery or until discharge. SPSS25.0 was used for statistical analysis. RESULTS: Compared with the NBS group, the number of elderly patients with high frailty level in BS group was more (P = 0.048). There is correlation between BS and POD (OR: 4.954, 95%CI 1.034-23.736, P = 0.045), and most of the POD patients in BS group behave as hyperactive type. CONCLUSION: The occurrence of intraoperative BS is associated with POD, and elderly patients with frailty are more likely to have intraoperative BS. BS can be used as a predictor of POD.

Efficacy and safety of crisaborole in patients with mild-to-moderate atopic dermatitis and other atopic comorbidities.

Background: Crisaborole is a nonsteroidal anti-inflammatory phosphodiesterase 4 inhibitor that is approved for the treatment of patients with mild-to-moderate atopic dermatitis (AD); however, the efficacy and safety of crisaborole in patients with AD and other atopic comorbidities have not been investigated. Objective: This post hoc pooled analysis of the pivotal phase III studies (CrisADe CORE 1 and CORE 2) assessed the efficacy and safety of crisaborole versus vehicle in patients aged ≥ 2 years with mild-to-moderate AD and other atopic comorbidities. Methods: Patients with mild-to-moderate AD and a medical history of asthma, allergic rhinitis, or food allergies were identified. Efficacy assessments included the proportion of patients who achieved Investigator's Static Global Assessment (ISGA) success at day 29, ISGA clear or almost clear at day 29, and improvement in the Severity of Pruritus Scale score at week 4. Safety was assessed via treatment-emergent adverse events (TEAEs). Results: This analysis included 1522 patients (crisaborole, 1016; vehicle, 506); 26.2, 15.9, and 16.5% had a medical history of asthma, allergic rhinitis, and food allergies, respectively. The mean age was 12.2 years. A significantly greater proportion of patients treated with crisaborole achieved ISGA success at day 29 compared with patients treated with vehicle for most subgroups analyzed. Furthermore, a significantly greater proportion of patients treated with crisaborole achieved ISGA clear or almost clear at day 29 across all subgroups and demonstrated improvement in the Severity of Pruritus Scale score at week 4 versus patients treated with vehicle in most of the subgroups. Overall, most TEAEs were mild or moderate in severity; the most common treatment-related TEAE in patients with atopic comorbidities was application-site pain (crisaborole, 5.1%; vehicle, 1.7%). Conclusion: Crisaborole was efficacious and well tolerated in patients with mild-to-moderate AD and other atopic comorbidities, which suggested that crisaborole should be considered for the management of AD in this population.

Demographics and Baseline Disease Characteristics of Early Responders to Crisaborole for Atopic Dermatitis.

INTRODUCTION: Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate atopic dermatitis (AD). This post hoc, pooled analysis identified demographic characteristics associated with early response to crisaborole. METHODS: Early response was defined as day 8 Investigator’s Static Global Assessment (ISGA) success (clear [0] or almost clear [1] with ≥2-grade improvement), ISGA clear/almost clear, or Severity of Pruritus Scale (SPS) response (≥1-point improvement). Correlations between early response and day-29 response were calculated. RESULTS: Patients were more likely to be early ISGA success responders if they were aged <12 years (P=0.0023), were white (P=0.0316), had moderate baseline disease by ISGA (P=0.0003), had not received prior AD treatment (P=0.0213), had disease duration shorter than or equal to the median (≤6.45 years; P=0.0349), or did not concurrently use antihistamines (P=0.0148). Similar early response results were observed for patients achieving ISGA clear or almost clear; however, they were more likely to have mild baseline disease by ISGA (P<0.0001) or mild percentage of treatable body surface area involvement (5 to <16; P<0.0001). Patients aged <12 years (P=0.0001) or with moderate baseline disease (P=0.0475) were more likely to be early responders based on SPS criteria. By all 3 definitions, patients who achieved early response at day 8 were more likely to be responders at day 29 (P<0.0001). CONCLUSION: Based on this analysis, patients aged <12 years were more likely to be early responders to crisaborole per all 3 definitions. Early response to crisaborole was a predictor of response at day 29.

Topical Agents for the Treatment of Atopic Dermatitis

Approval of the new topical phosphodiesterase 4 inhibitor crisaborole ointment, 2%, to treat mild-to-moderate atopic dermatitis (AD) warrants careful consideration of available efficacy and safety data for topical therapies to contribute to a better understanding of the role of crisaborole in the treatment of mild-to-moderate AD. A literature review was conducted to identify results of randomized, blinded, vehicle-controlled trials of topical agents for the treatment of AD published from January 1, 1997 to April 30, 2018. This review summarizes the efficacy and safety data of topical therapies including corticosteroids, calcineurin inhibitors, and crisaborole and it shows that comparison among available agents is difficult because of differing methodologies used across clinical trials and that there is considerable variability in safety reporting among AD trials. Published clinical studies for crisaborole demonstrate its efficacy and manageable safety profile. J Drugs Dermatol. 2020;19(1):50-64. doi:10.36849/JDD.2020.4508

Improvement in disease severity and pruritus outcomes with crisaborole ointment, 2%, by baseline atopic dermatitis severity in children and adolescents with mild-to-moderate atopic dermatitis.

BACKGROUND/OBJECTIVES: Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate atopic dermatitis (AD). This pooled post hoc analysis of two phase 3 trials (NCT02118766, NCT02118792) assessed improvement and time to improvement in Investigator's Static Global Assessment (ISGA) and Severity of Pruritus Scale (SPS) outcomes in pediatric patients with mild-to-moderate AD. METHODS: Patients aged ≥2 years were randomly assigned 2:1 to receive twice-daily crisaborole or vehicle for 28 days. Patients aged 2-17 years were pooled for this analysis. Proportions of patients and time to achieving ISGA success (clear [0] or almost clear [1] with ≥2-grade improvement from baseline), ISGA clear/almost clear, ≥1-grade improvement in ISGA, SPS success (SPS score ≤1 with ≥1-grade improvement), or ≥1-grade improvement in SPS score were analyzed and stratified by baseline ISGA. RESULTS: At first postbaseline assessment (day 8), significantly higher proportions of crisaborole- than vehicle-treated patients achieved ISGA success, ISGA clear/almost clear, ≥1-grade ISGA improvement, SPS success, or ≥1-grade improvement in SPS regardless of baseline ISGA. Differences were significantly greater over time for all outcomes for patients with moderate baseline ISGA and numerically greater for those with mild baseline ISGA. Median times to ISGA and SPS outcomes were shorter for crisaborole versus vehicle. CONCLUSION: Improvement in ISGA and SPS outcomes were observed with crisaborole in pediatric patients with mild-to-moderate baseline AD.

Crisaborole and atopic dermatitis skin biomarkers: An intrapatient randomized trial.

BACKGROUND: Crisaborole ointment 2% is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate atopic dermatitis (AD). The mechanism of action of crisaborole and its effects on lesional measures of disease severity are not yet well defined. OBJECTIVE: This phase 2a, single-center, vehicle-controlled, intrapatient study was designed to further characterize the mechanism of action of crisaborole through evaluation of clinical efficacy and changes in skin biomarkers in adults (n = 40) with mild-to-moderate AD. METHODS: Two target lesions were randomized in an intrapatient (1:1) manner to double-blind crisaborole/vehicle applied twice daily for 14 days. Patients then applied crisaborole (open-label) to all affected areas for 28 days. Punch biopsy specimens were collected for biomarker analysis at baseline, day 8 (optional), and day 15. RESULTS: Crisaborole treatment resulted in early improvement in lesional signs/symptoms versus vehicle, with improvement in pruritus (pruritus numeric rating scale) observed as early as 24 hours after the first application. Crisaborole-treated lesions showed significant percentage improvement from baseline in lesional transcriptomic profile compared with vehicle at day 8 (91.15% vs 36.02%, P < 10-15) that was sustained until day 15 (92.90% vs 49.59%, P < 10-15). Crisaborole significantly modulated key AD biomarkers versus vehicle, including TH2 and TH17/TH22 pathways and epidermal hyperplasia/proliferation. Molecular profiles and epidermal pathology normalized toward nonlesional skin and correlated with clinical changes in lesion severity and barrier function. CONCLUSION: Crisaborole reversed biomarker profiles of skin inflammation and barrier function, with associated improvements in clinical efficacy measures, highlighting the therapeutic utility of targeting phosphodiesterase 4 in patients with AD.

Tavaborole 5% Topical Solution for the Treatment of Toenail Onychomycosis in Pediatric Patients: Results from a Phase 4 Open-Label Study

Background: This study was designed to evaluate the safety, tolerability, pharmacokinetics (PK), and efficacy of tavaborole in pediatric patients. Study Design: In this open-label, single-arm study, pediatric patients (aged 6 to <17 years) with distal subungual onychomycosis affecting ≥20% of the target great toenail applied tavaborole once daily to all affected toenails (2 drops/great toenail, 1 drop/other toenail) for 48 weeks. In addition, a maximal-use subgroup (aged 12 to <17 years) applied tavaborole to all 10 toenails and ≤2 mm of surrounding skin for the first 28 days. Results: Treatment-emergent adverse events (TEAEs) were reported by 55.6% of patients; the most frequently reported (≥5% of patients) were nasopharyngitis, contusion, sinusitis, and vomiting. Most TEAEs and local treatment reactions (LTRs) were mild or moderate and considered unrelated to treatment. There was 1 serious AE (severe appendicitis, considered unrelated to treatment) and there were no deaths, discontinuations because of AEs, or dose adjustments because of AEs. The most frequently reported LTRs were erythema and scaling. The incidence of LTRs diminished over time. Tavaborole was absorbed systemically, and plasma concentrations were measurable. The PK parameters determined in this study under maximal-use conditions indicate that steady state was achieved within the study period. For efficacy, 8.5% of patients achieved complete cure (clear nail and negative mycology [negative fungal culture and negative potassium hydroxide wet mount]) at week 52, and 14.9% achieved complete/almost complete cure at week 52 (clear or almost clear nail [≤5% dystrophic or discolored distal toenail plate] and negative mycology). Conclusion: Tavaborole was well tolerated in this pediatric population, and safety, PK, and efficacy profiles were comparable with those in adults.

Tofacitinib versus methotrexate in rheumatoid arthritis.

BACKGROUND: Methotrexate is the most frequently used first-line antirheumatic drug. We report the findings of a phase 3 study of monotherapy with tofacitinib, an oral Janus kinase inhibitor, as compared with methotrexate monotherapy in patients with rheumatoid arthritis who had not previously received methotrexate or therapeutic doses of methotrexate. METHODS: We randomly assigned 958 patients to receive 5 mg or 10 mg of tofacitinib twice daily or methotrexate at a dose that was incrementally increased to 20 mg per week over 8 weeks; 956 patients received a study drug. The coprimary end points at month 6 were the mean change from baseline in the van der Heijde modified total Sharp score (which ranges from 0 to 448, with higher scores indicating greater structural joint damage) and the proportion of patients with an American College of Rheumatology (ACR) 70 response (≥70% reduction in the number of both tender and swollen joints and ≥70% improvement in three of five other criteria: the patient's assessment of pain, level of disability, C-reactive protein level or erythrocyte sedimentation rate, global assessment of disease by the patient, and global assessment of disease by the physician). RESULTS: Mean changes in the modified total Sharp score from baseline to month 6 were significantly smaller in the tofacitinib groups than in the methotrexate group, but changes were modest in all three groups (0.2 points in the 5-mg tofacitinib group and <0.1 point in the 10-mg tofacitinib group, as compared with 0.8 points in the methotrexate group [P<0.001 for both comparisons]). Among the patients receiving tofacitinib, 25.5% in the 5-mg group and 37.7% in the 10-mg group had an ACR 70 response at month 6, as compared with 12.0% of patients in the methotrexate group (P<0.001 for both comparisons). Herpes zoster developed in 31 of 770 patients who received tofacitinib (4.0%) and in 2 of 186 patients who received methotrexate (1.1%). Confirmed cases of cancer (including three cases of lymphoma) developed in 5 patients who received tofacitinib and in 1 patient who received methotrexate. Tofacitinib was associated with increases in creatinine levels and in low-density and high-density lipoprotein cholesterol levels. CONCLUSIONS: In patients who had not previously received methotrexate or therapeutic doses of methotrexate, tofacitinib monotherapy was superior to methotrexate in reducing signs and symptoms of rheumatoid arthritis and inhibiting the progression of structural joint damage. The benefits of tofacitinib need to be considered in the context of the risks of adverse events. (Funded by Pfizer; ORAL Start ClinicalTrials.gov number, NCT01039688.).

Efficacy and safety of open-label etanercept on extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis and psoriatic arthritis: part 1 (week 12) of the CLIPPER study.

OBJECTIVE: To investigate the efficacy and safety of etanercept (ETN) in paediatric subjects with extended oligoarticular juvenile idiopathic arthritis (eoJIA), enthesitis-related arthritis (ERA), or psoriatic arthritis (PsA). METHODS: CLIPPER is an ongoing, Phase 3b, open-label, multicentre study; the 12-week (Part 1) data are reported here. Subjects with eoJIA (2-17 years), ERA (12-17 years), or PsA (12-17 years) received ETN 0.8 mg/kg once weekly (maximum 50 mg). Primary endpoint was the percentage of subjects achieving JIA American College of Rheumatology (ACR) 30 criteria at week 12; secondary outcomes included JIA ACR 50/70/90 and inactive disease. RESULTS: 122/127 (96.1%) subjects completed the study (mean age 11.7 years). JIA ACR 30 (95% CI) was achieved by 88.6% (81.6% to 93.6%) of subjects overall; 89.7% (78.8% to 96.1%) with eoJIA, 83.3% (67.2% to 93.6%) with ERA and 93.1% (77.2% to 99.2%) with PsA. For eoJIA, ERA, or PsA categories, the ORs of ETN vs the historical placebo data were 26.2, 15.1 and 40.7, respectively. Overall JIA ACR 50, 70, 90 and inactive disease were achieved by 81.1, 61.5, 29.8 and 12.1%, respectively. Treatment-emergent adverse events (AEs), infections, and serious AEs, were reported in 45 (35.4%), 58 (45.7%), and 4 (3.1%), subjects, respectively. Serious AEs were one case each of abdominal pain, bronchopneumonia, gastroenteritis and pyelocystitis. One subject reported herpes zoster and another varicella. No differences in safety were observed across the JIA categories. CONCLUSIONS: ETN treatment for 12 weeks was effective and well tolerated in paediatric subjects with eoJIA, ERA and PsA, with no unexpected safety findings.

Impact of Crisaborole in Treatment-Experienced Patients With Mild-to-Moderate Atopic Dermatitis.

Background: Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of patients with mild-to-moderate atopic dermatitis (AD). Objective: To assess the efficacy and safety of crisaborole in patients with AD who had received prior treatment with (a) corticosteroids (systemic or topical) or topical calcineurin inhibitors (TCIs) or (b) topical corticosteroids (TCSs) or TCIs or (c) who were treatment-naive (TN). Methods: This post hoc analysis comprised patients aged ≥2 years with mild-to-moderate AD. Patients were assigned (2:1) to receive crisaborole or vehicle twice daily for 28 days. Patient response was assessed with the Investigator's Static Global Assessment (ISGA), Dermatology Life Quality Index (DLQI), Children's Dermatology Life Quality Index (CDLQI), and Dermatitis Family Impact (DFI) tools. Safety was also assessed. Results: A significantly higher percentage of patients treated with crisaborole versus vehicle achieved ISGA success regardless of treatment history. Patients treated with crisaborole had significant reductions in DLQI, CDLQI, and DFI scores versus those who received vehicle regardless of treatment history, with the exception of DLQI and DFI scores in the TN group. Crisaborole was well tolerated in all subgroups. Conclusion: Crisaborole demonstrated a favorable efficacy and safety profile in both treatment-experienced and TN patients.

A phase 3 randomized, double-blind, multicenter comparative study evaluating the effect of etanercept versus methotrexate on radiographic outcomes, disease activity, and safety in Japanese subjects with active rheumatoid arthritis.

OBJECTIVES: The aim of this phase 3, double-blind study was to compare the radiographic and clinical effects of etanercept (ETN) versus methotrexate (MTX) over 52 weeks in Japanese subjects with active rheumatoid arthritis. METHODS: The study population comprised 550 subjects with inadequate response to ≥1 disease-modifying anti-rheumatic drugs who were randomized to treatment groups of ETN 25 mg twice weekly (BIW; n = 182), ETN 10 mg BIW (n = 192), or MTX (≤8.0 mg/week; n = 176). RESULTS: Of the 550 subjects initially enrolled in the three treatment groups, 21.6% discontinued the study; a significantly higher proportion of those who withdrew from the study due to lack of efficacy were in the MTX (21.6%) group compared with the ETN 25 mg (3.3%) and ETN 10 mg (6.8%) groups (P < 0.001). Mean change from baseline in the modified total Sharp score at week 52 (primary endpoint) was significantly lower in the ETN 25 mg [3.33; standard error (SE), 0.73] and ETN 10 mg (5.19; SE 0.93) groups than in the MTX group (9.82; SE 1.16; P < 0.0001 vs. either ETN group). Compared with subjects receiving MTX, significantly higher percentages of subjects treated with ETN 25 and 10 mg achieved American College of Rheumatology (ACR) ACR20 and ACR50 response rates at all time points (P < 0.01). ETN was well-tolerated, with no unexpected safety findings. CONCLUSIONS: ETN 25 mg BIW and ETN 10 mg BIW slowed radiographic progression and improved clinical outcomes more effectively than MTX in this Japanese population.

Effect of opioid-free anesthesia on the incidence of postoperative nausea and vomiting: A meta-analysis of randomized controlled studies.

BACKGROUND: Research on opioid-free anesthesia has increased in recent years; however, it has never been determined whether it is more beneficial than opioid anesthesia. This meta-analysis was primarily used to assess the effect of opioid-free anesthesia compared with opioid anesthesia on the incidence of postoperative nausea and vomiting. METHODS: We searched the electronic databases of PubMed, the Cochrane Library, Web of Science and Embase from 2014 to 2022 to identify relevant articles and extract relevant data. The incidence of postoperative nausea and vomiting, time to extubation, pain score at 24 hours postoperatively, and time to first postoperative rescue analgesia were compared between patients receiving opioid-free anesthesia and those receiving standard opioid anesthesia. Differences in the incidence of postoperative nausea and vomiting were evaluated using risk ratios (95% confidence interval [CI]). The significance of the differences was assessed using mean differences and 95% CI. The heterogeneity of the subject trials was evaluated using the I2 test. Statistical analysis was performed using the RevMan 5.4 software. RESULTS: Fourteen randomized controlled trials, including 1354 participants, were evaluated in the meta-analysis. As seen in the forest plot, the OFA group had a lower risk of postoperative nausea and vomiting than the control group (risk ratios = 0.41, 95% CI: 0.33-0.51, P < .00001; n = 1354), and the meta-analysis also found that the OFA group had lower postoperative analgesia scores at 24 hours (P < .000001), but time to extubation (P = .14) and first postoperative resuscitation analgesia time (P < .54) were not significantly different. CONCLUSIONS: Opioid-free anesthesia reduces the incidence of postoperative nausea and vomiting while providing adequate analgesia without interfering with postoperative awakening.

Impact of Crisaborole on Sleep Outcomes in Pediatric Patients with Mild-to-Moderate Atopic Dermatitis.

INTRODUCTION: Using data from three clinical trials, the effect of crisaborole treatment on sleep outcomes for pediatric patients with atopic dermatitis (AD) and their families was examined. METHODS: This analysis comprised patients aged 2 to < 16 years from the double-blind phase 3 CrisADe CORE 1 (NCT02118766) and CORE 2 (NCT02118792) studies, families of patients aged 2 to < 18 years from CORE 1 and CORE 2, and patients aged 3 months to < 2 years from the open-label phase 4 CrisADe CARE 1 study (NCT03356977), all with mild-to-moderate AD who received crisaborole ointment 2% twice daily for 28 days. Sleep outcomes were assessed via the Children's Dermatology Life Quality Index and Dermatitis Family Impact questionnaires in CORE 1 and CORE 2 and the Patient-Oriented Eczema Measure questionnaire in CARE 1. RESULTS: In CORE 1 and CORE 2, a significantly lower proportion of crisaborole-treated patients than vehicle-treated patients reported sleep disruption at day 29 (48.5% versus 57.7%, p = 0.001). The proportion of families whose sleep was affected by their child's AD in the preceding week was also significantly lower in the crisaborole group (35.8% versus 43.1%, p = 0.02) at day 29. At day 29 in CARE 1, the proportion of crisaborole-treated patients who experienced ≥ 1 night of disturbed sleep in the previous week decreased by 32.1% from baseline. CONCLUSION: These results suggest that crisaborole improves sleep outcomes in pediatric patients with mild-to-moderate AD and their families.

Atopic dermatitis (AD), also known as eczema, is a chronic skin disease that causes red or flaky skin patches that can become infected and itch. Children with AD often experience sleep disturbance, including difficulty falling asleep, restless sleep, waking up more frequently, and daytime drowsiness. Problems with sleep quality negatively impact children with AD, as well as their caregivers. Crisaborole ointment is applied to the skin and has been shown to improve the symptoms of AD in children and adults. This study examined how treatment with crisaborole affected sleep quality for children and their caregivers in three clinical trials. Children in these studies took crisaborole for 28 days. Researchers found that crisaborole treatment improved sleep in children with mild-to-moderate AD and their caregivers. This was determined using four measures. First, a smaller proportion of children who were treated with crisaborole experienced sleep disruption compared with those to whom a vehicle was applied (an ointment with no drug). Second, a smaller proportion of caregivers of children with AD who were treated with crisaborole reported effects on their sleep, compared with children to whom a vehicle was applied. Third, a smaller proportion of children with AD who were treated with crisaborole, as well as their caregivers, had ≥ 1 night per week of disturbed sleep after treatment compared with before treatment. Fourth, the caregivers of children treated with crisaborole reported significantly less exhaustion and tiredness because of the child's AD. These results suggest that treatment with crisaborole improves sleep outcomes in children with mild-to-moderate AD and their caregivers.

Once-Daily Crisaborole Ointment, 2%, as a Long-Term Maintenance Treatment in Patients Aged ≥ 3 Months with Mild-to-Moderate Atopic Dermatitis: A 52-Week Clinical Study.

BACKGROUND: Topical treatments for atopic dermatitis (AD) used reactively often fail to achieve lasting disease control; many of these therapies are associated with safety concerns that limit long-term use. Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate AD that has potential as a long-term maintenance therapy. OBJECTIVE: The aim was to evaluate the long-term efficacy and safety of crisaborole once daily (QD) compared to vehicle QD as a maintenance therapy to reduce the incidence of flares in patients with AD who previously responded to crisaborole twice daily (BID). METHODS: CrisADe CONTROL was a randomized, double-blind, vehicle-controlled, 52-week, phase III study of patients aged ≥ 3 months with mild-to-moderate AD involving ≥ 5% treatable body surface area. Eligible patients received crisaborole BID during an open-label run-in period of up to 8 weeks. Responders were randomly assigned in the double-blind maintenance period to receive either crisaborole QD or vehicle QD. Responders were defined as patients who achieved Investigator's Static Global Assessment (ISGA) success (ISGA score of 0 [clear] or 1 [almost clear] with a ≥ 2-grade improvement) and ≥ 50% improvement in Eczema Area and Severity Index total score (EASI-50) from baseline. Patients who experienced a flare (ISGA score ≥ 2) during the double-blind maintenance period switched to crisaborole BID for up to 12 weeks. During this period, patients were assessed every 4 weeks; if the flare resolved (ISGA score ≤ 1), patients resumed their assigned treatment. The primary endpoint was flare-free maintenance until onset of the first flare. Key secondary endpoints were number of flare-free days, number of flares, and maintenance of pruritus response until onset of the first flare. The incidence of treatment-emergent adverse events was also analyzed. RESULTS: Overall, 497 patients entered the open-label run-in period with crisaborole BID, of which 270 patients were randomized into the 52-week double-blind maintenance period of the study. Of the 270 patients, 135 were randomly assigned to the crisaborole QD group and 135 were randomly assigned to the vehicle QD group. Median time of flare-free maintenance was longer for patients who received crisaborole versus vehicle (111 vs 30 days, respectively; p = 0.0034). The mean number of flare-free days was higher for patients who received crisaborole versus vehicle (234.0 vs 199.4 days, respectively; p = 0.0346). The mean number of flares was lower for patients who received crisaborole versus vehicle (0.95 vs 1.36, respectively; p = 0.0042). No clear trend was observed in maintenance of pruritus response between crisaborole- and vehicle-treated patients. Crisaborole was well tolerated, with no new or unexpected safety findings when used as maintenance treatment. CONCLUSIONS: Crisaborole QD was effective and well tolerated for long-term maintenance treatment and flare reduction in adult and pediatric patients with mild-to-moderate AD.

Atopic dermatitis (AD) is an immuno-inflammatory skin disease that can last a long time. It causes skin lesions and intense itching. Topical AD treatments used reactively often fail to control the disease over a long period of time. Many are associated with safety concerns that limit long-term use. Crisaborole ointment is a nonsteroidal treatment for the skin and is used to treat mild-to-moderate AD. Previous studies showed that using crisaborole twice daily was effective and had few side effects in patients with mild-to-moderate AD. This study evaluated how effective and safe long-term treatment with once-daily crisaborole was compared with an ointment with no drug (vehicle). The study included patients aged ≥ 3 months with mild-to-moderate AD whose AD improved after previous treatment with twice-daily crisaborole. This study was designed to investigate how much crisaborole reduced the incidence of AD flares over 52 weeks in these patients.The study included 270 patients whose AD had improved after treatment with twice-daily crisaborole. Of these patients, 135 were randomly assigned to receive crisaborole once a day and 135 to receive vehicle once a day. Patients who received crisaborole had a significantly longer time before experiencing AD flares than those who received vehicle. Crisaborole was well tolerated, and no new or unexpected side effects were found when used as a once-daily maintenance treatment for 52 weeks. These results indicate that once-daily treatment with crisaborole could be a potential long-term maintenance treatment option in children and adults with mild-to-moderate AD.

Etanercept Withdrawal and Retreatment in Nonradiographic Axial Spondyloarthritis: Results of RE-EMBARK, an Open-Label Phase IV Trial.

OBJECTIVE: RE-EMBARK investigated etanercept (ETN) withdrawal and retreatment in patients with nonradiographic axial spondyloarthritis (nr-axSpA) achieving inactive disease. METHODS: Patients received ETN and a background nonsteroidal antiinflammatory drug for 24 weeks in period 1 (P1); those achieving inactive disease (Ankylosing Spondylitis Disease Activity Score [ASDAS] with C-reactive protein [CRP] < 1.3) discontinued ETN for 40 weeks or less (period 2 [P2]). Patients who flared (ASDAS with erythrocyte sedimentation rate [ESR] ≥ 2.1) were retreated for 12 weeks in period 3 (P3). The primary endpoint was the proportion of patients with inactive disease who flared within 40 weeks of ETN withdrawal. Baseline characteristics were analyzed post hoc as predictors of maintenance and regaining of inactive disease, respectively, using univariate logistic and stepwise multivariable logistic regression models. RESULTS: The proportion of patients experiencing flare following ETN withdrawal (P2) increased from 22.3% (25/112) after 4 weeks to 67% (77/115) after 40 weeks; 74.8% (86/115) experienced flare at any time during P2. Median time to flare was 16.1 weeks. Most patients (54/87, 62.1%) who were retreated with ETN in P3 reachieved inactive disease. Absence of both sacroiliitis detected on magnetic resonance imaging (MRI) and high-sensitivity CRP (hs-CRP) > 3 mg/L at baseline predicted inactive disease maintenance in P2 following ETN withdrawal in multivariable analysis; male sex and age younger than 40 years predicted regaining of inactive disease in P3 after flare/retreatment. There were no unexpected safety signals. CONCLUSION: Approximately 25% of patients maintained inactive disease for 40 weeks after discontinuing ETN. Absence of both MRI sacroiliitis and high hs-CRP at baseline predicted response maintenance after ETN withdrawal. (ClinicalTrials.gov: NCT02509026).

Potential application of PS-OCT in the safety assessment of non-steroidal topical creams for atopic dermatitis treatment.

Crisaborole 2% ointment is a non-steroidal treatment for mild-moderate atopic dermatitis (AD) and may produce fewer adverse effects than topical corticosteroids (TCS). We used PS-OCT to quantify dermal collagen at baseline and after 29 days of treatment with crisaborole and betamethasone valerate (BMV), in 32 subjects. PS-OCT detected a mean increase 1 × 10-6, 95% CI (6.3, 1.37) × 10-6 in dermal birefringence following TCS use (p < 0.0001, ad-hoc, not powered), whereas a change of -4 × 10-6, 95% CI (-32, 24) × 10-6 was detected for crisaborole (p = 0.77, ad-hoc, not powered). These results could suggest a differential effect on dermal collagen between the two compounds. PS-OCT may thus find an important role in safety assessment of novel AD treatment' and larger trials are warranted.

Effects of different levels of controlled hypotension on regional cerebral oxygen saturation and postoperative cognitive function in patients undergoing total knee arthroplasty.

Background: Controlled hypotension technique was usually used to reduce intraoperative bleeding, and it could improve visualization of the surgical field during total knee arthroplasty (TKA). However, inappropriate controlled hypotension, through reducing cerebral blood flow or cerebral perfusion pressure, may cause postoperative cognitive dysfunction (POCD), so it is important to identify the appropriate level of controlled hypotension. Objective: To investigate the effects of different levels of controlled hypotension on regional cerebral oxygen saturation and postoperative cognitive function in patients undergoing TKA. Methods: Patients meeting inclusion criteria were enrolled through preoperative visits and basic information was obtained. The patients were randomly divided into three groups: Group A, MAP was maintained at 90-100% of the baseline; Group B, MAP was maintained at 80-90% of the baseline; Group C, MAP was maintained at 70-80% of the baseline. The MAP, HR, and rSO2 were observed and recorded during the operation. The C-reactive protein (CRP), hemoglobin (Hb) and MMSE score at 1, 3, and 7 days after operation were recorded. SPSS25.0 was used for data analysis. Result: When the MAP had a decrease among the three groups, rSO2 did not decrease significantly, and none of the patients experienced POCD which was measured by MMSE. And there was no correlation between the decline in rSO2 and that in MAP. Conclusion: No POCD was experienced in the three groups, and we recommend that the controlled hypotensive target indicated by MAP was maintained at 70-80% of the baseline which not only decreases intraoperative bleeding and improve the quality of the surgical field, but also is still within safe levels.
