A retrospective analysis of treatment patterns, drug discontinuation and healthcare costs in Crohn's disease patients treated with biologics

BACKGROUND/AIMS

This real-world analysis evaluated the persistence and direct healthcare costs of Crohn's Disease (CD) patients treated with biologics in Italy.

METHODS

A retrospective analysis on administrative databases of Italian healthcare entities, covering 10.4 million residents, was performed. Adult CD patients under biologics between 2015 and 2020 were included and attributed to first/second treatment line based on absence/presence of biologic prescriptions 5-years before index-date (first biologic prescription).

RESULTS

Of 16,374 CD patients identified, 1,398 (8.5%) were biologic-treated: 1,256 (89.8%) in first line and 135 (9.7%) in second line. Kaplan-Meier curves estimated a higher persistence for ustekinumab-treated patients followed by vedolizumab, infliximab and adalimumab, in both lines. Considering baseline variables and adalimumab as reference, infliximab in first line (HR: 0.537) and ustekinumab in first (HR: 0.057) and second line (HR: 0.213) were associated with significantly reduced risk of drug-discontinuation. First line total/average healthcare direct-costs were €13,637, €11,201, €17,104 and €18,340 in patients persistent on adalimumab, infliximab, ustekinumab and vedolizumab, respectively.

CONCLUSIONS

This real-world analysis showed differences in persistence over 12-months between biologic treatments, being higher in ustekinumab-treated group, followed by vedolizumab, infliximab and adalimumab. Patients' management was associated with comparable direct healthcare costs among treatment lines, mainly driven by drug-related expenses.

A Systematic Review of the Economic and Health-Related Quality of Life Impact of Advanced Therapies Used to Treat Moderate-to-Severe Ulcerative Colitis

INTRODUCTION

The clinical benefits of advanced therapies (i.e., biologics and small-molecule drugs) in the treatment of moderate-to-severe ulcerative colitis (UC) have been demonstrated; however, there is less clarity regarding the economic and health-related quality of life (HRQoL) impact of these treatments. We conducted a systematic literature review to synthesize data on cost, healthcare resource utilization (HCRU), and HRQoL for patients who received approved advanced therapies for moderate-to-severe UC in the United States and Europe.

METHODS

Databases including MEDLINE, Embase, the Database of Abstracts of Reviews of Effects (DARE), the National Health Service Economic Evaluation Database (NHS EED), and EconLit were searched systematically to identify observational studies published between January 1, 2010 and October 14, 2021 that assessed the impact of advanced therapies on cost, HCRU, and/or HRQoL in adults with moderate-to-severe UC. Supplementary gray literature searches of conference proceedings from the past 4 years (January 2018 to October 2021) were also performed.

RESULTS

47 publications of 40 unique cost/HCRU studies and 13 publications of nine unique HRQoL studies were included. Findings demonstrated that biologics have a positive impact on indirect costs (i.e., productivity, presenteeism, and absenteeism) and HRQoL. High costs of biologics were not always fully offset by reductions in cost and HCRU associated with disease management. For many patients, treatment switching and dose escalations were required, thus increasing drug costs, particularly when switching across treatment classes.

CONCLUSION

These findings highlight a high unmet need for therapies for moderate-to-severe UC that can reduce the healthcare burden and impact on society. Further research is warranted, as the reported evidence was limited by the small sample sizes of some treatment groups within a study.

The Magnitude of Crohn's Disease Direct Costs in Health Care Systems (from Different Perspectives): A Systematic Review

BACKGROUND

The prevalence of inflammatory bowel disease (IBD) has been increasing worldwide, causing high impact on the quality of life of patients and an increasing burden for health care systems. In this systematic review, we reviewed the literature concerning the direct costs of Crohn's disease (CD) for health care systems from different perspectives: regional, economic, and temporal.

METHODS

We searched for original real-world studies examining direct medical health care costs in Crohn's disease. The primary outcome measure was the mean value per patient per year (PPY) of total direct health care costs for CD. Secondary outcomes comprised hospitalization, surgery, CD-related medication (including biologics), and biologics mean costs PPY.

RESULTS

A total of 19 articles were selected for inclusion in the systematic review. The studies enrolled 179 056 CD patients in the period between 1997 and 2016. The pooled mean total cost PPY was €6295.28 (95% CI, €4660.55-€8503.41). The pooled mean hospitalization cost PPY for CD patients was €2004.83 (95% CI, €1351.68-€2973.59). The major contributors for the total health expenditure were biologics (€5554.58) and medications (€3096.53), followed by hospitalization (€2004.83) and surgery (€1883.67). No differences were found between regional or economic perspectives, as confidence intervals overlapped. However, total costs were significantly higher after 2010.

CONCLUSIONS

Our review highlighted the burden of CD for health care systems from different perspectives (regional, economic, and temporal) and analyzed the impact of the change of IBD treatment paradigm on total costs. Reducing the overall burden can depend on the increase of remission rates to further decrease hospitalizations and surgeries.

An overview of ozanimod as a therapeutic option for adults with moderate-to-severe active ulcerative colitis

INTRODUCTION

Ulcerative colitis (UC) is a chronic inflammatory condition of the gastrointestinal tract involving a dysregulated immune response. Sphingosine-1-phosphate (S1P) is involved in immune cell regulation. S1P-receptor modulators, such as ozanimod, inhibit lymphocyte migration and have therapeutic potential in UC.

AREAS COVERED

Ozanimod is the first S1P-receptor modulator approved for the treatment of UC. It acts as a functional antagonist, causing internalization of S1P receptors on T-cells. Lymphocyte egress from lymph nodes is inhibited, and migration to sites of active inflammation is curtailed. There are several S1P-receptor subtypes, present in various organs, which inform understanding of ozanimod's side-effect profile including bradycardia and macular edema. In this review, the authors discuss the mechanism of action, pharmacokinetics, clinical efficacy, and safety profile of ozanimod in the treatment of patients with moderate-to-severe UC.

EXPERT OPINION

The S1P-receptor modulator ozanimod is an oral small molecule with a rapid onset of action and a novel therapeutic mechanism in the treatment of UC. It is an effective treatment both in bio-naïve and bio-exposed patients. Although the safety profile of ozanimod looks favorable, more long-term data are needed. Further studies are required to compare ozanimod to currently available therapies to best define its positioning in UC treatment algorithms.

Dose-escalation of adalimumab, golimumab or ustekinumab in inflammatory bowel diseases: characterization and implications in real-life clinical practice

OBJECTIVES

Dose-escalation is a common practice to optimize treatment with subcutaneously administered biologicals in Crohn's disease (CD) and ulcerative colitis (UC). However, limited data is available on the extent of dose-escalation in real-life. Here, we analyzed treatment persistence, dose-escalation, concomitant corticosteroid use, and costs of adalimumab, golimumab, and ustekinumab in inflammatory bowel diseases (IBD).

METHODS

This was a nationwide, retrospective, non-interventional registry study. All adult patients who were diagnosed with CD or UC and had purchased adalimumab, golimumab, or ustekinumab from Finnish pharmacies between 2008 and 2018 were included in the study and followed up for 24 months after treatment initiation.

RESULTS

A total of 2884 patients were included in the analyses. For adalimumab, treatment persistence was higher for CD patients compared to UC patients both at months 12 (46.2% versus 37.1%; p < .0001) and 24 (26.1% versus 19.7%; p < 0.0001). For golimumab (UC), treatment persistence was 48.3% at month 12 and 28.1% at month 24. The 12-month treatment persistence rate for patients on ustekinumab (CD) was 47.1%. Cumulative doses exceeding the regular dosing according to the summary of product characteristics (SPC), was observed for adalimumab in CD during the first 6 months of treatment (62.9% of the treatment periods), golimumab in the later stages of the UC treatment (52-54% of treatment periods at months 7-24), and ustekinumab during the first 6 months (70.7%).

CONCLUSIONS

Based on this study, dose-escalation of subcutaneously administered biologicals is a common clinical practice in IBD. This has implications for treatment costs, use of concomitant medications, and treatment outcomes.
