Baricitinib, an oral Janus kinase (JAK)1/JAK2 inhibitor, is indicated in the European Union and Japan for treatment of moderate-to-severe atopic dermatitis (AD) in adults who are candidates for systemic therapy. In the ongoing, placebo-controlled, phase 3 trial BREEZE-AD5, once-daily oral baricitinib 2-mg monotherapy improved disease in moderate-to-severe AD patients who had an inadequate response or intolerance to topical corticosteroids. This post-hoc analysis aimed to identify responders to baricitinib 2 mg, using a proposed clinical tailoring approach based on baseline body surface area (BSA) affected and early clinical improvement, in BREEZE-AD5.
Methods
Classification and regression tree method was used to evaluate baseline predictors for the proportion of patients achieving ≥ 75% improvement in Eczema Area and Severity Index (EASI75) at week 16 among baricitinib 2-mg-treated patients. Two-by-two contingency tables evaluated the association between early response, defined as ≥ 50% improvement in BSA or ≥ 3-point improvement in Itch Numeric Rating Scale from baseline at weeks 4 or 8, and response at week 16 for the proportion of patients achieving EASI75, validated Investigator Global Assessment for AD (vIGA-AD) score of 0 or 1, or ≥ 4-point improvement in Itch (Itch ≥ 4), respectively. Missing data were imputed as non-responder.
Results
At week 16, EASI75 and vIGA-AD (0,1) were achieved by 37.5% and 31.7% of baricitinib 2-mg-treated patients with baseline BSA 10–50% compared with 9.5% and 4.8% with BSA > 50%. Early response in skin inflammation or itch at week 4 was associated with corresponding EASI75, vIGA-AD (0,1), and Itch ≥ 4 of 55.4%, 48.2%, and 39.3% at week 16, while early response at week 8 was associated with 66.7%, 56.1%, and 42.1% of patients achieving these endpoints.
Conclusion
Baseline BSA of 10–50% and early clinical improvement after 4 or 8 weeks of baricitinib 2-mg treatment may identify patients most likely to benefit from long-term baricitinib 2-mg therapy.

This post-hoc analysis aimed to identify patients who are likely to benefit from baricitinib 2 mg, using a clinical tailoring approach based on baseline body surface area (BSA) affected and early clinical improvement, in the phase 3 monotherapy trial BREEZE-AD5.
What was learned from the study?
Patients with moderate-to-severe AD affecting between 10% and 50% of their BSA account for the majority of week 16 responders to baricitinib 2 mg, and clinical assessment of patients after 4–8 weeks of initiation of baricitinib 2-mg treatment identified those who are likely to benefit from long-term baricitinib 2-mg therapy.
The proposed clinical tailoring approach for baricitinib 2 mg allows for the treatment of patients who are more likely to respond to therapy, and rapid decision on discontinuation of treatment for those who are not likely to benefit from baricitinib 2 mg.

Introduction
Atopic dermatitis (AD) is a common, chronic, inflammatory skin disease characterized by complex pathophysiology and heterogeneous clinical phenotypes [1‐3]. AD symptoms include intense itch, sleep disturbance, and skin pain, which significantly impact patient quality of life and work productivity [4‐6]. Emollients and topical corticosteroids (TCS) are the mainstay of AD therapy [7‐9]. In patients with moderate-to-severe AD for whom topical therapy does not adequately control the signs and symptoms of disease, addition of phototherapy and/or systemic treatment is recommended [10, 11]. Systemic treatments can be associated with variable efficacy and unnecessary cycling through ineffective medications resulting in prolonged burden and delayed improvements [10, 12]. Therefore, prediction of treatment efficacy is becoming increasingly important with the emergence of new therapies. An understanding of which patients are most likely to benefit from therapy can help tailor therapies to individual patient needs. Tailored therapeutic approaches can significantly refine the management of AD through improving patient experience with a treatment, increasing cost-effectiveness of a therapy, and ensuring that only patients who are likely to benefit from therapy are exposed to a given treatment.
Baricitinib, an oral selective Janus kinase (JAK) 1 and JAK2 inhibitor [13], is indicated in the European Union and Japan and being evaluated in the USA and other countries for treatment of moderate-to-severe AD in adult patients who are candidates for systemic therapy. Dependent upon country-specific approvals, the recommended starting dose of baricitinib for adults with moderate-to-severe AD is 2 mg or 4 mg [14‐16]. In BREEZE-AD5, an ongoing, randomized, placebo-controlled, phase 3 trial of moderate-to-severe AD patients who had an inadequate response or intolerance to TCS, once-daily oral baricitinib 2-mg monotherapy improved several clinical signs and symptoms of AD at week 16 compared with placebo, with a safety profile consistent with previous studies of baricitinib 2 mg in AD [17, 18]. The objective of this post-hoc analysis was to identify patients who are most likely to benefit from baricitinib 2 mg, using a proposed clinical tailoring approach based on baseline body surface area (BSA) affected at drug initiation and early clinical improvement, in the phase 3 monotherapy trial BREEZE-AD5.
Methods
Study Design and Patients
BREEZE-AD5 (NCT03435081) is an ongoing phase 3 randomized, double-blind, placebo-controlled trial conducted in the USA and Canada [17]. Patients (N = 440) were randomized 1:1:1 to receive once-daily placebo, baricitinib 1 mg, or baricitinib 2 mg (Fig. S1). Eligible patients were ≥ 18 years of age and had a diagnosis of AD, as defined by the American Academy of Dermatology [19], ≥ 12 months prior to screening. Enrolled patients had moderate-to-severe disease, defined by baseline Eczema Area and Severity Index (EASI) score ≥ 16, validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) score ≥ 3, and BSA involvement of ≥ 10%. Patients had a documented history of inadequate response or intolerance to topical therapies within 6 months before screening. Patients discontinued topical therapy 2 weeks and systemic therapy 4 weeks before randomization. This trial was conducted in accordance with the ethical principles of the Helsinki Declaration of 1964 and its later amendments and Good Clinical Practice guidelines and approved by the appropriate institutional review boards/ethics committees at each study site (Table S1), including the Quorum Review IRB (approval #33039). All patients provided written informed consent.

Outcomes
The primary endpoint of the trial was the proportion of patients who achieved 75% improvement in EASI score (EASI75) at week 16. Two secondary endpoints included the proportion of patients who achieved a vIGA-AD score of 0 (clear) or 1 (almost clear), with a ≥ 2-point improvement from baseline, and the proportion of patients who achieved a ≥ 4-point improvement from baseline in the Itch Numeric Rating Scale (NRS) [17]. These endpoints were analyzed in this post-hoc analysis in the subgroup of patients most likely to benefit from baricitinib 2-mg treatment.
Statistical Analyses
In this post-hoc analysis, classification and regression tree algorithm (CART) was used to identify baseline predictors of response. A variety of baseline measures were assessed, including, but not limited to patient demographics, prior treatment history, baseline disease severity [such as vIGA-AD, EASI, BSA, Itch NRS, Atopic Dermatitis Sleep Scale, Dermatology Life Quality Index (DLQI), SCORing Atopic Dermatitis, Hospital Anxiety Depression Scale], and laboratory parameters. Response was defined as the proportion of patients achieving EASI75 at week 16 among those treated with baricitinib 2 mg in the intent-to-treat (ITT) population. Two-by-two contingency tables with associated sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were generated between CART-identified baseline predictors and EASI75. As a sensitivity analysis, the same method was applied to identify baseline predictors for the proportion of patients who achieved vIGA-AD (0,1) at week 16. Sensitivity and NPV were examined closely. Sensitivity represents the proportion of patients with certain baseline characteristics, among those who were responders at week 16. A high sensitivity value indicates that most responders were identified by characteristics through the algorithm. NPV represents the proportion of patients who were not responders at week 16, among those without the same baseline characteristics. A high NPV indicates that patients in this group would likely not benefit from therapy. After baseline subgroups were identified using the CART method, response rate for EASI75, vIGA-AD (0,1), and ≥ 4-point improvement in Itch NRS by visits were analyzed with logistics regression models. Baseline disease severity (vIGA-AD), continuous version of endpoint at baseline, treatment group, baseline subgroup, and treatment-by-baseline subgroup interaction were included as model terms.
After identification of a baseline predictor of response, further analyses were conducted to determine if early response could be used to further refine the patient selection. The goal of this second analysis was to quickly identify any additional patients who are less likely to benefit from therapy and allow for quick clinical decision on whether to transition such patients to alternative therapies. Two-by-two contingency tables were used to evaluate the association between early response in skin inflammation (≥ 50% improvement in BSA) or itch (≥ 3-point improvement in Itch NRS) at week 4 or week 8, and response at week 16 for EASI75, vIGA-AD (0,1), and ≥ 4-point improvement in Itch NRS. Early measures of improvement (≥ 50% improvement in BSA and ≥ 3-point improvement in Itch NRS) were selected for being considered a meaningful improvement, easily noticeable by patients and physicians, and applicable in clinical practice [20]. EASI75, vIGA-AD (0,1), and ≥ 4-point improvement in Itch NRS are accepted regulatory endpoints in AD, which allowed for comparison between the ITT population results and this subgroup analysis. Sensitivity, specificity, PPV, and NPV were used to evaluate the performance of the two-by-two classification table.
Data collected after any rescue or treatment discontinuation were considered as missing. All missing data were imputed as non-responder. To use the same ITT population for evaluating skin inflammation and itch simultaneously in association with early improvement and week 16 response, a conservative approach to define improver and responder was used: any patient with a baseline Itch NRS score < 3 was automatically classified as a non-improver for ≥ 3-point improvement in Itch NRS at week 4 or 8, and any patient with a baseline Itch NRS score < 4 was automatically classified as a non-responder for ≥ 4-point improvement in Itch NRS at week 16.
Results
Classification and Regression Tree Analysis
Baseline BSA was identified as the strongest predictor of treatment outcome to optimize accuracy, with a cutoff of 50% being optimal for sensitivity and NPV. Application of baseline BSA 10–50% to predict response to baricitinib 2 mg resulted in selection of 90.7% (NPV 90.5%) and 94.3% (NPV 95.2%) of EASI75 and vIGA-AD (0,1) responders at week 16, respectively, in the overall study population.
Baseline Demographics and Disease Severity
Baseline demographics were balanced among the overall ITT population and baseline BSA 10–50% and BSA > 50% subgroups across treatment arms. EASI scores were lower in the BSA 10–50% subgroup compared with the ITT population; however, the overall burden of disease symptoms, including itch, sleep, skin pain, and impact on quality of life, was comparable between the two groups (Table 1).

Clinical Response among Patients with Baseline BSA 10–50%
We evaluated the impact of baseline BSA on clinical responses to baricitinib 2-mg monotherapy in the ITT population over time. Baricitinib 2 mg resulted in a significantly higher proportion of patients achieving EASI75 and vIGA-AD (0,1) at week 16 in those with baseline BSA 10–50%, but not in BSA > 50% (Fig. 1A and B). Among patients with baseline BSA 10–50%, EASI75 and vIGA-AD (0,1) were achieved at week 16 in 37.5% and 31.7% with baricitinib 2 mg, compared with 9.9% and 6.9% with placebo (p ≤ 0.001 for both). In contrast, in patients with baseline BSA > 50%, EASI75 and IGA (0,1) responses at week 16 were only achieved in 9.5% and 4.8% with baricitinib 2 mg, compared with 4.3% and 2.2% with placebo (p = not significant for both) (Fig. 1A and B). Response rates for itch were also slightly higher in patients with baseline BSA 10–50% treated with baricitinib 2 mg (Fig. 1C).

Early meaningful response in skin inflammation (≥ 50% improvement in BSA) or itch (≥ 3-point improvement in Itch NRS) at week 8 or week 4, was able to further refine which patients were most likely to benefit from baricitinib 2-mg therapy longer term (Fig. 2). Among baricitinib 2-mg-treated patients with baseline BSA 10–50%, early response in skin inflammation or itch at week 8 was associated with EASI75, vIGA-AD (0,1), and ≥ 4-point improvement in Itch NRS of 66.7%, 56.1%, and 42.1% at week 16, compared with 2.1%, 2.1%, and 0% for those who did not have an early response at week 8 (Fig. 2A, C, and E). Assessment of early response in skin inflammation or itch at week 4 was associated with corresponding EASI75, vIGA-AD (0,1), and ≥ 4-point improvement in Itch NRS of 55.4%, 48.2%, and 39.3% at week 16, compared with 16.7%, 12.5%, and 4.2% for those who did not have an early response at week 4 (Fig. 2B, D, and F). High NPVs showed that, without early improvement in skin inflammation or itch, there were almost no EASI75, vIGA-AD (0,1), and ≥ 4-point improvement in Itch NRS responders at week 16 with baricitinib 2-mg treatment (Table 2). Among baricitinib 2-mg-treated patients with baseline BSA 10–50%, early response in skin inflammation or itch was associated with improved clinical response at week 16.

Discussion
Personalized medicine has long been a goal in clinical practice [21, 22]. Providers seek to identify which patients are most likely to benefit from treatment in order to increase the probability of success with a given therapy and minimize risk of exposure to an ineffective treatment. In this study, we demonstrated that baricitinib 2 mg provides enhanced efficacy in patients with a baseline BSA ranging from 10% to 50%, with higher response rates for EASI75 and vIGA-AD (0,1), compared with patients with a baseline BSA > 50%.
Early assessment of clinical response was defined as an improvement of at least 50% in BSA or an improvement of at least 3 points in Itch NRS from baseline at week 4 or week 8. Early response in skin inflammation or itch resulted in an additional significant increase in patient response at week 16 among baricitinib 2-mg-treated patients with baseline BSA 10–50%, with as many as two-thirds of patients achieving an EASI75 at week 16 and over half of the patients achieving a vIGA-AD (0,1) at week 16. This is in contrast to 37.5% and 31.7% of responders observed for EASI75 and vIGA-AD (0,1), respectively, in the overall baseline BSA 10–50% group, and 29.5% and 24.0%, respectively, in the ITT population [17]. These high efficacy results were observed while maintaining a very high NPV for the analyses, showing that an early decision for discontinuation of therapy is possible in patients with a BSA of 10–50% at baseline. Patients who respond to baricitinib 2 mg experience clinical benefit early in their course of treatment. Patients who do not respond to baricitinib 2-mg treatment within the first 4–8 weeks are unlikely to respond to treatment in the long term.
Although BSA and associated EASI scores were lower in patients with BSA 10–50% at baseline, overall burden of disease by symptoms was comparable between the groups. Patients’ baseline itch, sleep disturbance due to itch, skin pain, Patient Oriented Eczema Measures scores, and quality of life (DLQI) were comparable between the groups, confirming the significant burden of disease in patients with baseline BSA 10–50%. Although the proposed clinical tailoring approach uses baseline BSA, a small increase in itch response was also observed in patients with baseline BSA 10–50% compared with patients with baseline BSA > 50%. Importantly, 100% of the patients who responded to baricitinib 2 mg with a ≥ 4-point improvement in Itch NRS at week 16 had achieved a ≥ 3-point improvement by week 8 (Table 2, sensitivity = 1.0, NPV = 1.0).
A limitation to this study is that these are post-hoc subgroup analyses as opposed to prespecified subgroup analyses [23]. The analyses focused on the 2-mg dose of baricitinib, and the lack of data from the 4-mg dose is a further limitation. In addition, patients discontinued topical and systemic treatments 2 and 4 weeks prior to randomization, respectively. The discontinuation of topical and systemic therapies weeks prior to the initiation of the study drug may lead to rescue earlier than if therapies were discontinued closer to the initiation of the clinical trial. In addition, this was a monotherapy trial. Although this study helped to better assess the impact of treatment in AD severity without the potential confounding effect of topical corticosteroids, topical calcineurin inhibitors, or topical phosphodiesterase-4 inhibitors, some of these treatments may be maintained in clinical practice during treatment. Other limitations are the lack of standardization in the assessment of BSA [24], as well as the inconsistent performance of a full-body skin examination in clinical practice. The BSA affords a rapid assessment on physical examination that may help to guide clinical decision-making, particularly with the advent of new therapies in the treatment armamentarium for AD.

In conclusion, patients with moderate-to-severe AD affecting between 10% and 50% of their BSA accounted for the majority of responders to baricitinib 2 mg. The clinical assessment of patients after 4–8 weeks of initiation of baricitinib 2-mg treatment predicted which patients are likely to benefit from long-term therapy. This analysis may allow for a precision-medicine approach to therapy in moderate-to-severe AD.
