Abstract

Introduction

In the phase 2 CELEST study, positive efficacy results were obtained with the Janus kinase 1 inhibitor upadacitinib for adult patients with moderate to severe Crohn’s disease. We present the health-related quality of life and work productivity improvement results with upadacitinib from CELEST.

Methods

CELEST (NCT02365649) was a double-blind study where patients were randomized 1:1:1:1:1:1 in the 16-week induction period to placebo or upadacitinib 3 mg twice daily (BID), 6 mg BID, 12 mg BID, 24 mg BID, or 24 mg once daily (QD). Patients completing the induction period were re-randomized 1:1:1 to receive upadacitinib 3 mg BID, 12 mg BID, or 24 mg QD for 36 weeks or 3 mg BID, 6 mg BID, or 12 mg BID (after amendment). Inflammatory Bowel Disease Questionnaire (IBDQ), European Quality of Life-5 Dimensions visual analog scale (EQ-5D VAS), and Work Productivity and Activity Impairment (WPAI) questionnaire outcomes were assessed at baseline and Weeks 8, 16, and 52.

Results

At Week 16, a significant percentage (P ≤ 0.05) of patients receiving upadacitinib 6-mg BID dose or higher achieved IBDQ response (IBDQ score change ≥ 16 points; 49%–57% for upadacitinib vs. 24% for placebo) and IBDQ remission, except 24 mg QD (IBDQ score ≥ 170; 26%–39% for upadacitinib vs. 11% for placebo). Greater improvements in IBDQ total score, EQ-5D VAS, and activity impairment from baseline (P ≤ 0.1) versus placebo were also observed. Larger improvements (P ≤ 0.1) in IBDQ response and total score and EQ-5D VAS were observed at Week 8 with 6 and 24 mg BID versus placebo, with improvements for all dosages maintained or greater at Week 52 for IBDQ, EQ-5D VAS, and WPAI endpoints, in particular for the 12-mg BID group.

Conclusion

Improvements in health-related quality of life and work productivity were achieved and sustained with upadacitinib in patients with moderate to severe Crohn’s disease.

Key Summary Points

Why carry out this study?
Crohn’s disease has a major impact on a patient’s health-related quality of life, emphasizing the need for novel treatments.
We evaluated whether the Janus kinase 1 inhibitor upadacitinib improved quality of life and work productivity for patients with moderate to severe Crohn’s disease based on data from a phase 2b study.
What was learned from this study?
Statistically significant improvements from baseline were achieved as early as 8 weeks in quality of life and 16 weeks for work productivity and sustained for up to 52 weeks with upadacitinib in patients with moderate to severe Crohn’s disease.
These phase 2 findings support the further assessment of safety, efficacy, quality of life, and work productivity outcomes with upadacitinib in phase 3 studies.

Introduction

Crohn’s disease (CD) is a chronic, inflammatory gastrointestinal disease with a prevalence of 318.5 cases per 100,000 persons in North America and 322.0 cases per 100,000 persons in Western Europe [1–5]. CD is characterized by chronic diarrhea, abdominal pain, and fatigue with disease progression leading to bowel damage and disability [1–4]. Consequently, this disease has a significant negative impact on a patient’s health-related quality of life (HRQOL), including emotional and psychological issues, social and family interactions, and work-related difficulties [1, 6–8].

Current treatments for moderate to severe CD include corticosteroids, immunosuppressants, and biologic agents [2, 4]. However, issues with inadequate response, loss of response, and adverse events with these agents indicate the need for alternative medical treatments [2, 4, 9, 10]. This is particularly significant for the improvement of patients’ HRQOL and work productivity.

One relevant new target for CD is Janus kinase (JAK)-1, an important component of the signaling transduction pathway of cytokine receptors which play a major role in the pathogenesis of this disease [11–13]. Upadacitinib (ABT-494), an oral selective and reversible inhibitor of JAK-1 that more potently inhibits JAK-1 compared with JAK-2 and JAK-3, is currently being evaluated for the treatment of CD [14, 15]. Upadacitinib has recently been approved for adult patients with moderate to severe rheumatoid arthritis [16].

CELEST, a phase 2, placebo-controlled study of upadacitinib was completed in adult patients with moderate to severe CD who had inadequate response or intolerance to immunosuppressants or tumor necrosis factor (TNF) antagonists [15]. Upadacitinib induced endoscopic remission in a significant proportion of patients compared with placebo at Week 12 or 16. Efficacy was maintained for most endpoints through Week 52, with adverse events consistent with those from previous studies for JAK inhibitors [15]. However, the impact of JAK inhibition on HRQOL and work productivity for patients with CD is unknown. We now present the HRQOL and work productivity outcomes with upadacitinib for these patients at the end of the induction and maintenance periods from this phase 2 study.

Methods

Study Design

CELEST was a phase 2, 52-week, multicenter, double-blind, randomized study consisting of a 16-week placebo-controlled, induction period followed by a 36-week maintenance period (Clinicaltrials.gov identifier: NCT02365649) (Fig. 1) [15]. For the induction period, patients were randomized in a 1:1:1:1:1:1 ratio to receive placebo or the immediate-release formulation of upadacitinib in oral doses of 3 mg, 6 mg, 12 mg, or 24 mg twice daily (BID) or 24 mg once daily (QD). Patients who completed the 16-week induction period were re-randomized 1:1:1 to receive double-blind maintenance therapy with the immediate-release formulation of upadacitinib at 3 mg BID, 12 mg BID, or 24 mg QD for 36 weeks. A protocol amendment stopped the re-randomization into the 24-mg QD arm in the maintenance period and initiated a 6-mg BID arm. Patients who were already assigned to 24 mg QD continued to receive this dosage to the end of the study. All subsequent patients entering the maintenance period were re-randomized 1:1:1 to receive upadacitinib 3 mg, 6 mg, or 12 mg BID. Additional details have been previously reported [15].

This study was conducted in compliance with Good Clinical Practice guidelines, applicable local regulations, and the Declaration of Helsinki. This study protocol was approved by the relevant ethics committees or institutional review boards (see electronic supplementary material). All patients provided informed consent before study participation.

Study Participants

Patients 18–75 years old with confirmed ileal, ileocolonic, or colonic CD for ≥ 3 months, a CD Activity Index of 220–450, average daily liquid/very soft stool frequency ≥ 2.5 or daily abdominal pain score ≥ 2.0, and Simplified Endoscopic Score for Crohn's Disease (SES-CD) ≥ 6 (or ≥ 4 for those with isolated ileal disease) were included in the study. Patients were also required to have an inadequate response/intolerance to at least one of the TNF antagonists approved for CD (adalimumab, infliximab, or certolizumab pegol) or (based on protocol amendment) to azathioprine, mercaptopurine, or methotrexate. Additional inclusion/exclusion criteria have been previously reported in the manuscript presenting the primary CELEST study results [15].

Outcomes

The study endpoints were to evaluate the improvements in HRQOL and work productivity with upadacitinib after Weeks 8, 16, and 52 of treatment compared with placebo (Weeks 8 and 16) or the 3-mg dose (Week 52). HRQOL was assessed in terms of the Inflammatory Bowel Disease Questionnaire (IBDQ) and European Quality of Life-5 Dimensions (EQ-5D) index and visual analog scale (VAS). Work productivity was assessed with the Work Productivity and Activity Impairment (WPAI) questionnaire. HRQOL and work productivity measures are reported for baseline, Week 8, Week 16, and Week 52 timepoints.

IBDQ is a disease-specific instrument that has been validated and commonly used for CD [17–21]. IBDQ is composed of 32 items graded on a 7-point Likert scale, which contains four dimensional score domains: bowel, emotional, social, and systemic [17–19]. Total score ranges from 32 to 224, with higher scores indicating better HRQOL. Outcomes measured in this study were assessed at Weeks 8, 16, and 52: (1) percentage of patients with an increase in IBDQ score of ≥ 16 points (minimum clinically important difference [22]) from baseline (IBDQ response); (2) percentage of patients with IBDQ score ≥ 170 (IBDQ remission [23]); (3) mean change from baseline in IBDQ total score; (4) change in IBDQ domain scores from baseline to Week 16 and from Week 16 to Week 52; and (5) IBDQ score over the 52-week study period.

EQ-5D is a standardized, non-disease–specific instrument for describing and valuing quality-of-life consisting of five dimensions (index score): mobility, self-care, usual activities, pain/discomfort, and anxiety/depression [24]. Each dimension has 5 levels: no problem, slight problem, moderate problem, severe problem, or unable to do the activity. EQ-5D also contains a VAS that ranges from 0 to 100. Patients are asked to indicate the level that describes their current level of function or experience for each dimension. As a measure of health status, it provides a descriptive profile and can be used to generate a single index value for health status, where 0 is the worst health and 100 is the best health you can imagine. The outcome measured was mean change from baseline to Weeks 8 and 16 and from Week 16 to Week 52 in EQ-5D VAS score.

WPAI assesses the impact of the condition on work productivity losses and impairment in daily activity and is comprised of four domains: activity impairment, presenteeism (impairment while working), overall work impairment (productivity loss), and absenteeism (work time missed) [25–27]. Scores are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity. The outcome measured was mean change from baseline to Weeks 8 and 16 and from Week 16 to Week 52 in WPAI scores.

Statistical Analyses

All outcome measures were part of the primary analysis in the CELEST study. A full description of the statistical methods is reported in the primary manuscript of this study [15].

For the induction period, the modified intent-to-treat (mITT) analysis dataset was used for all the analyses. The mITT analysis dataset included randomized patients who took at least one dose of study drug during the induction period. Study outcomes were examined among treatment groups, with placebo as the reference group. The proportion of patients with IBDQ response and IBDQ remission, respectively, were analyzed based on the Cochran–Mantel–Haenszel test, adjusting for induction baseline SES-CD (< 15 and ≥ 15). For IBDQ total and domain, EQ-5D index score and VAS, and WPAI scores, analysis of covariance (ANCOVA) was used to evaluate within-group changes from baseline to Weeks 8 and 16, adjusting for treatment, baseline disease severity, and baseline value. Missing data were reported using nonresponder imputation (NRI) and last observation carried forward (LOCF).

The intent-to-treat (ITT) analysis dataset included re-randomized patients in the maintenance period who were clinical responders (defined as ≥ 30% decrease from baseline in average daily very soft/liquid stool frequency OR ≥ 30% decrease from baseline in average daily abdominal pain score, and neither worse than baseline) in the induction period. Study outcomes were examined among treatment groups, with upadacitinib 3 mg BID as the reference group. The proportion of patients with IBDQ response and IBDQ remission were analyzed based on the chi-square test (or Fischer’s exact test if ≥ 20% of the cells had expected cell count < 5). Mean change in IBDQ, EQ-5D VAS, and WPAI from Week 16 to Week 52 were analyzed using ANCOVA, adjusting for treatment and induction baseline value. Missing data were reported using NRI and observed cases.

All tests of significance were at the 2-sided 10% level of significance (P ≤ 0.1), as used in the previously reported primary study [15], and which is commonly used in phase 2b trials associated with dose selection for future phase 3 studies [28]. All reported P values are nominal. All data analyses were performed using SAS v.9.4 (SAS Institute, Cary, NC, USA).

Results

Study Population

A total of 220 patients with moderately to severely active CD were randomized to induction treatment, with 180 completing the induction phase and re-randomized to upadacitinib for the maintenance period (Fig. 1). Of these 180 patients, 153 received upadacitinib during induction of whom 94 patients were clinical responders. Maintenance phase results are provided for the 94 clinical responders.

At baseline, median disease duration was 9.6 years, with a high proportion (96%) having prior TNF antagonist exposure and 64% exposed to two or more biologics (Table 1) [15]. Baseline IBDQ scores, EQ-5D index score and VAS values, and WPAI domain scores were numerically similar between treatment groups (Table 1).

IBDQ Changes with Upadacitinib

At Week 16, a significantly higher percentage of patients had a clinically meaningful IBDQ response with upadacitinib compared with placebo for all dosages, with the upadacitinib 6-mg and 24-mg BID groups having the most significant increases (P ≤ 0.01) (Fig. 2a). Greater percentages of patients with a clinically meaningful IBDQ response were also observed at Week 8 with upadacitinib 6 mg BID, 12 mg BID, and 24 mg QD relative to placebo (P ≤ 0.1) and at Week 52 with upadacitinib 6 mg BID and 12 mg BID relative to the 3-mg dosage (P ≤ 0.05).

A significantly greater percentage of patients also achieved IBDQ remission at Week 16 with upadacitinib versus placebo for the 6-mg, 12-mg, and 24-mg BID dosages (P ≤ 0.05) (Fig. 2b), with higher percentages of patients achieving IBDQ remission at Week 8 with upadacitinib versus placebo, particularly for the 24-mg BID dose (P ≤ 0.1). At Week 52 of the maintenance period, a numerically higher percentage of patients achieved IBDQ remission with all dosages of upadacitinib compared with Week 16, although no significant improvements were observed versus the 3-mg dosage.

Significant mean increases from baseline in IBDQ total score were obtained at Weeks 8 and 16 with both the upadacitinib 6-mg and 24-mg BID dosages compared with placebo (P ≤ 0.05) (Fig. 2c; see Table S1 in the electronic supplementary material). IBDQ total scores rose further in the maintenance period with upadacitinib treatment for all treatment groups (Fig. 2c; see Table S2 in the electronic supplementary material).

Improvements in the individual IBDQ domain scores (bowel, social, emotional, and systemic) with upadacitinib were generally consistent with the total IBDQ score changes, with patients receiving upadacitinib 6 mg BID and 24 mg BID having the most significant mean changes in the induction period (P ≤ 0.05). In the maintenance period, the highest mean change from induction baseline was achieved with upadacitinib 12 mg BID compared with the other treatment groups for the individual IBDQ domain scores (see Fig. S1 in the electronic supplementary material).

EQ-5D Changes with Upadacitinib

Similar to IBDQ, upadacitinib 6 mg BID and 24 mg BID had the most significant mean EQ-5D VAS score increases from baseline compared with the other treatment groups in the induction period at both Weeks 8 and 16 (P values of 0.014 and 0.011 at Week 16, respectively, vs. placebo) (Fig. 3; see Table S1 in the electronic supplementary material). In the maintenance period, the upadacitinib 12-mg BID group had significant improvements from induction baseline in EQ-5D VAS score versus upadacitinib 3 mg BID (P = 0.052) (Fig. 3; see Table S2 in the electronic supplementary material).

The greatest changes from baseline in the EQ-5D index scores versus placebo were with the 12-mg BID (P ≤ 0.1) and 24-mg BID (P ≤ 0.01) dosages at Week 8 and with the 3-mg BID (P ≤ 0.1), 6-mg BID (P ≤ 0.05), 24-mg BID (P ≤ 0.01), and 24-mg QD (P ≤ 0.1) dosages at Week 16 (see Fig. S2 and Table S1 in the electronic supplementary material). In the maintenance period, numerical improvements were observed with the upadacitinib 12-mg BID group from induction baseline in EQ-5D index score versus upadacitinib 3 mg BID (see Fig. S2 and Table S2 in the electronic supplementary material).

WPAI Changes with Upadacitinib

Decreases of at least 7% in each of the WPAI domains are regarded as sizable changes and minimally important differences [29]. Compared with placebo, clinically meaningful improvements of more than 7% in activity impairment were observed with the 6-mg BID (P ≤ 0.05) and 24-mg BID (P ≤ 0.01) dosages; and in overall work impairment with 24 mg BID (P ≤ 0.1) at Week 16 (Fig. 4; see Table S1 in the electronic supplementary material). Although improvements in WPAI were numerically greater at Week 52 of the maintenance period compared with Week 16 for all upadacitinib dosages, no significant increases versus the 3-mg BID dosage were observed (Fig. 4; see Table S2 in the electronic supplementary material).

Discussion

In this placebo-controlled trial, patients with moderately to severely active CD had significant improvements in HRQOL and work productivity outcomes after a 16-week induction treatment with upadacitinib which were sustained in a 36-week maintenance period. In particular, significant improvements with upadacitinib in HRQOL were achieved after 16 weeks of treatment in IBDQ with the 6-, 12-, and 24-mg BID dosages and in EQ-5D VAS and activity impairment with the 6- and 24-mg BID dosages versus placebo. For the 6- and 24-mg BID dosages, these improvements were observed as early as Week 8 for mean change from baseline in IBDQ and EQ-5D VAS scores compared with placebo. Further improvements were observed after 1 year of treatment, with 79% and 69% of patients achieving IBDQ response with the 6- and 12-mg BID dosages.

The results observed with the BID dose regimen were consistent with what was reported for the primary clinical and endoscopic efficacy results [15]. The reduced HRQOL improvements with the QD dose regimen during the maintenance period may potentially be because of its modest pharmacokinetic properties, as previously reported [15].

To the best of our knowledge, this is the first report on the effects of a JAK inhibitor on HRQOL and work productivity for CD. HRQOL and work productivity outcomes that were positively affected by upadacitinib in this study included symptoms and functioning, which are considered highly important to patients with CD. This includes outcomes related to bowel symptoms (e.g., frequent and loose bowel movements and abdominal cramping), systemic symptoms (e.g., fatigue and general feeling of being unwell), emotional functioning (e.g., feelings of frustration and depression), social impairment (e.g., avoiding activities where no restrooms are near and cancelling social events), and performing daily activities (e.g., housework, childcare, shopping, exercising, and studying) [18, 27, 30, 31]. Thus, the improvements with upadacitinib noted in this study could have a major impact on multiple aspects of a patient’s quality of life.

These HRQOL and work productivity results are consistent with the positive findings that were recently reported for the primary and key secondary endpoints from the CELEST study program for upadacitinib [15]. Additionally, these findings are in line with reports for biologics (e.g., TNF, interleukin-12/23, and integrin receptor antagonists) that patients who have clinical responses to these agents have HRQOL and work productivity benefits [32–37].

There is a considerable need for novel treatments for CD, particularly as current therapeutic options, including corticosteroids, immunomodulatory agents such as azathioprine, 6-mercaptopurine, or methotrexate, and biologics, such as TNF antagonists, are ineffective in a relevant percentage of patients and can be associated with adverse effects that can limit their use [2, 4, 9, 10]. The CELEST study enrolled patients with longstanding and refractory CD, and yet clinical remission was achieved by up to 27% of patients at Week 16 with upadacitinib (6 mg BD vs. 11% for placebo; P ≤ 0.1), and endoscopic remission was obtained by up to 22% of patients at Week 12 or 16 (24 mg BID, none for placebo, P ≤ 0.01) [15]. Safety findings were consistent with those from previous studies of JAK inhibitors [15]. Results from clinical, endoscopic, HRQOL, and work productivity endpoints in the CELEST study together indicate that there is a potential for JAK-1 inhibitors to be an additional option for the treatment of moderate to severe CD. As this is a dose-finding study with a limited number of patients per treatment group, and no clear dose-response across the HRQOL measures, a more robust phase 3 trial is ongoing to confirm these findings.

Another limitation of this study was the lack of a placebo control during the maintenance phase, in which the use of upadacitinib 3 mg BID as a comparator could have resulted in an underestimation of the improvements observed with the other upadacitinib dosages. Therefore, conclusions regarding the maintenance of effects observed in the induction phase need to be viewed with caution. Furthermore, with all maintenance studies including only responders, care must be taken when interpreting effect size and extrapolating results to all patients.

Conclusions

This is the first study to evaluate the impact of JAK inhibition on HRQOL and work productivity in patients with CD. We demonstrated that 16 weeks of induction therapy with upadacitinib resulted in significant improvements in HRQOL and work productivity in patients with moderately to severely active CD that were sustained with an additional 36 weeks of treatment. A phase 3 trial is currently being initiated to confirm safety, efficacy, and HRQOL and work productivity outcomes with upadacitinib from the phase 2 study in patients with moderately to severely active CD.
