Abrocitinib 100 mg Once Daily for Moderate-to-Severe Atopic Dermatitis: A Review of Efficacy and Safety, and Expert Opinion on Use in Clinical Practice.

ABSTRACT: Abrocitinib is a Janus kinase (JAK) 1-selective inhibitor approved for the treatment of moderate-to-severe atopic dermatitis (AD). Although specific dose recommendations for abrocitinib vary across regional product labels, abrocitinib 100 mg once daily is recommended as a starting and maintenance dose. This review summarizes the efficacy and safety of abrocitinib 100 mg once daily for patients with moderate-to-severe AD based on data from the pivotal phase 3 studies of the JAK1 Atopic Dermatitis Efficacy and Safety (JADE) clinical program, JADE MONO-1 (NCT03349060), JADE MONO-2 (NCT03575871), JADE COMPARE (NCT03720470), JADE TEEN (NCT03796676), and JADE REGIMEN (NCT03627767). Preliminary long-term efficacy and safety data are also summarized from the long-term extension study JADE EXTEND (NCT03422822). Expert opinion on use of abrocitinib 100 mg once daily in clinical practice is provided. In addition to efficacy, the decision to use abrocitinib for the treatment of AD should allow for individual patient factors such as age, comorbidities, previous therapy, quality of life, and treatment tolerability, and involve shared decision-making between the patient and clinician.

Project description:ImportanceAbrocitinib, an oral, once-daily Janus kinase 1 selective inhibitor, was effective and well tolerated in a phase 3 monotherapy trial of patients with moderate-to-severe atopic dermatitis (AD).ObjectiveTo investigate the efficacy and safety of abrocitinib in adolescents and adults with moderate-to-severe AD in an identically designed trial.Design, setting, and participantsThis phase 3, double-blinded, placebo-controlled, parallel-group randomized clinical trial included patients 12 years or older with a clinical diagnosis of moderate-to-severe AD for at least 1 year and inadequate response to topical medications given for at least 4 weeks within 6 months. Patients were enrolled from 115 centers in Australia, Bulgaria, Canada, China, Czechia, Germany, Hungary, Japan, South Korea, Latvia, Poland, United Kingdom, and the United States from June 29, 2018, to August 13, 2019. Data were analyzed from September 13 to October 25, 2019.InterventionsPatients were randomly assigned (2:2:1) to receive once-daily oral abrocitinib in 200- or 100-mg doses or placebo for 12 weeks.Main outcomes and measuresThe coprimary end points were the proportion of patients achieving Investigator Global Assessment (IGA) response (ie, clear [0] or almost clear [1], with improvement of ≥2 grades) and the proportion of patients achieving at least 75% improvement in Eczema Area and Severity Index score (EASI-75) at week 12. Key secondary end points included the proportion of patients achieving a Peak Pruritus Numerical Rating Scale (PP-NRS) response (ie, improvement of ≥4 points) at week 12. Other secondary end points included the proportion of patients achieving at least 90% improvement in EASI score (EASI-90). Safety was assessed via adverse events and laboratory monitoring.ResultsA total of 391 patients (229 male [58.6%]; mean [SD] age, 35.1 [15.1] years) were included in the analysis; of these, 155 received abrocitinib, 200 mg/d; 158, abrocitinib, 100 mg/d; and 78, placebo. Among patients with available data at week 12, greater proportions of patients in the 200- and 100-mg abrocitinib groups vs the placebo group achieved IGA (59 of 155 [38.1%] and 44 of 155 [28.4%] vs 7 of 77 [9.1%]; P < .001) and EASI-75 (94 of 154 [61.0%] and 69 of 155 [44.5%] vs 8 of 77 [10.4%]; P < .001), greater estimated proportions achieved PP-NRS (55.3% [95% CI, 47.2%-63.5%] and 45.2% [95% CI, 37.1%-53.3%] vs 11.5% [95% CI, 4.1%-19.0%]; P < .001), and/or greater proportions achieved EASI-90 (58 of 154 [37.7%] and 37 of 155 [23.9%] vs 3 of 77 [3.9%]) responses. Adverse events were reported for 102 patients (65.8%) in the 200-mg group, 99 (62.7%) in the 100-mg group, and 42 (53.8%) in the placebo group; serious adverse events were reported for 2 patients (1.3%) in the 200-mg group, 5 (3.2%) in the 100-mg group, and 1 (1.3%) in the placebo group. Decreases in platelet count (2 [1.3%]) and laboratory values indicating thrombocytopenia (5 [3.2%]) were reported in the 200-mg group.Conclusions and relevanceMonotherapy with once-daily oral abrocitinib was effective and well tolerated in adolescents and adults with moderate-to-severe AD.Trial registrationClinicalTrials.gov Identifier: NCT03575871.

Project description:BackgroundThe efficacy, safety and tolerability of lumiracoxib, a novel selective cyclooxygenase-2 (COX-2) inhibitor, has been demonstrated in previous studies of patients with osteoarthritis (OA). As it is important to establish the long-term safety and efficacy of treatments for a chronic disease such as OA, the present study compared the effects of lumiracoxib at doses of 100 mg once daily (o.d.) and 100 mg twice daily (b.i.d.) with those of celecoxib 200 mg o.d. on retention on treatment over 1 year.MethodsIn this 52-week, multicentre, randomised, double-blind, parallel-group study, male and female patients (aged at least 40 years) with symptomatic primary OA of the hip, knee, hand or spine were randomised (1:2:1) to lumiracoxib 100 mg o.d. (n = 755), lumiracoxib 100 mg b.i.d. (n = 1,519) or celecoxib 200 mg o.d. (n = 758). The primary objective of the study was to demonstrate non-inferiority of lumiracoxib at either dose compared with celecoxib 200 mg o.d. with respect to the 1-year retention on treatment rate. Secondary outcome variables included OA pain in the target joint, patient's and physician's global assessments of disease activity, Short Arthritis assessment Scale (SAS) total score, rescue medication use, and safety and tolerability.ResultsRetention rates at 1 year were similar for the lumiracoxib 100 mg o.d., lumiracoxib 100 mg b.i.d. and celecoxib 200 mg o.d. groups (46.9% vs 47.5% vs 45.3%, respectively). It was demonstrated that retention on treatment with lumiracoxib at either dose was non-inferior to celecoxib 200 mg o.d. Similarly, Kaplan-Meier curves for the probability of premature discontinuation from the study for any reason were similar across the treatment groups. All three treatments generally yielded comparable results for the secondary efficacy variables and all treatments were well tolerated.ConclusionLong-term treatment with lumiracoxib 100 mg o.d., the recommended dose for OA, was as effective and well tolerated as celecoxib 200 mg o.d. in patients with OA.Trial registrationclinicaltrials.gov NCT00145301.

Project description:ObjectiveMajor depressive disorder (MDD) is a significant public health concern and challenges health care providers to intervene with appropriate treatment. This article provides an overview of efficacy and safety information for duloxetine 60 mg/day in the treatment of MDD, including its effect on painful physical symptoms (PPS).DesignA literature search was conducted for articles and pooled analyses reporting information regarding the use of duloxetine 60 mg/day in placebo-controlled trials.SettingPlacebo-controlled, active-comparator, short- and long-term studies were reviewed.ParticipantsAdult (≥18 years) patients with MDD.MeasurementsEffect sizes for continuous outcome (change from baseline to endpoint) and categorical outcome (response and remission rates) were calculated using the primary measures of 17-item Hamilton Rating Scale for Depression (HAMD-17) or Montgomery-Åsberg Depression Rating Scale (MADRS) total score. The Brief Pain Inventory and Visual Analogue Scales were used to assess improvements in PPS. Glass estimation method was used to calculate effect sizes, and numbers needed to treat (NNT) were calculated based on HAMD-17 and MADRS total scores for remission and response rates. Safety data were examined via the incidence of treatment-emergent adverse events and by mean changes in vital-sign measures.ResultsTreatment with duloxetine was associated with small-to-moderate effect sizes in the range of 0.12 to 0.72 for response rate and 0.07 to 0.65 for remission rate. NNTs were in the range of 3 to 16 for response and 3 to 29 for remission. Statistically significant improvements (p≤0.05) were observed in duloxetine-treated patients compared to placebo-treated patients in PPS and quality of life. The safety profile of the 60-mg dose was consistent with duloxetine labeling, with the most commonly observed significant adverse events being nausea, dry mouth, diarrhea, dizziness, constipation, fatigue, and decreased appetite.ConclusionThese results reinforce the efficacy and tolerability of duloxetine 60 mg/day as an effective short- and long-term treatment for adults with MDD. The evidence of the independent analgesic effect of duloxetine 60 mg/day supports its use as a treatment for patients with PPS associated with depression. This review is limited by the fact that it included randomized clinical trials with different study designs. Furthermore, data from randomized controlled trials may not generalize well to real clinical practice.

Project description:BackgroundTopical 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.ObjectiveThe 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).MethodsCrisADe 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.ResultsOverall, 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.ConclusionsCrisaborole QD was effective and well tolerated for long-term maintenance treatment and flare reduction in adult and pediatric patients with mild-to-moderate AD.Trial registrationClinicalTrials.gov, NCT04040192, 31 July 2019.

Project description:Background and objectiveAbrocitinib is a Janus kinase 1 inhibitor in development for the treatment of atopic dermatitis (AD). This work characterized orally administered abrocitinib population pharmacokinetics in healthy individuals, patients with psoriasis, and patients with AD and the effects of covariates on abrocitinib exposure.MethodsAbrocitinib concentration measurements (n = 6206) from 995 individuals from 11 clinical trials (seven phase I, two phase II, and two phase III) were analyzed, and a non-linear mixed-effects model was developed. Simulations of abrocitinib dose proportionality and steady-state accumulation of maximal plasma drug concentration (Cmax) and area under the curve (AUC) were conducted using the final model.ResultsA two-compartment model with parallel zero- and first-order absorption, time-dependent bioavailability, and time- and dose-dependent clearance best described abrocitinib pharmacokinetics. Abrocitinib coadministration with rifampin resulted in lower exposure, whereas Asian/other race coadministration with fluconazole and fluvoxamine, inflammatory skin conditions (psoriasis/AD), and hepatic impairment resulted in higher exposure. After differences in body weight are accounted for, Asian participants demonstrated a 1.43- and 1.48-fold increase in Cmax and AUC, respectively. The overall distribution of exposures (Cmax and AUC) was similar in adolescents and adults after accounting for differences in total body weight.ConclusionsA population pharmacokinetics model was developed for abrocitinib that can be used to predict abrocitinib steady-state exposure in the presence of drug-drug interaction effects or intrinsic patient factors. Key covariates in the study population accounting for variability in abrocitinib exposures are Asian race and adolescent age, although these factors are not clinically meaningful.Clinical trial numbersNCT01835197, NCT02163161, NCT02201524, NCT02780167, NCT03349060, NCT03575871, NCT03634345, NCT03637790, NCT03626415, NCT03386279, NCT03937258.
