Economic impact of expanded use of biologic therapy for the treatment of rheumatoid arthritis and Crohn's disease in Argentina, Brazil, Colombia, and Mexico

Budget impact of upadacitinib in patients with moderate to severe rheumatoid arthritis in Argentina

OBJECTIVES.

To analyze the budget impact of upadacitinib (UPA) 15 mg + methotrexate (MTX) for the treatment of moderate-to-severe rheumatoid arthritis (RA) in patients with an inadequate response to conventional disease-modifying antirheumatic drugs (cDMARD-IR) from the perspective of social security and the private health sector in Argentina.

MATERIALS AND METHODS.

A budget impact analysis model was developed for a hypothetical cohort of 100,000 adults with health insurance coverage who were diagnosed with RA over a 5-year time horizon. The model parameters were obtained through literature review and validated by local experts. The costs are expressed in 2024 US dollars (USD).

RESULTS.

The introduction of UPA 15 mg + MTX for the treatment of moderate-to-severe RA and cDMARD-IR resulted in minimal increase, with a five-year total cumulative incremental cost of USD 1,855 for social security and USD 1,812 for the private health sector, representing 2% of the total budget. The acquisition cost of UPA was the most influential variable in the sensitivity analysis.

CONCLUSIONS.

The introduction of UPA 15 mg + MTX for the treatment of moderate-to-severe RA and cDMARD-IR can provide an effective treatment option with a minimal increase in costs for the healthcare system in Argentina, which is especially important in developing countries where health system budgets are more limited. Providing evidence-based estimates is a valuable tool for informing healthcare policies and can help policymakers make informed decisions about the allocation of healthcare resources to improve patient outcomes while also managing costs.

Motivation for the study. Rheumatoid arthritis (RA) is a disease that hasn’t cure, so it’s important to know the budget impact of treatment with upadacitinib (UPA) 15 mg + methotrexate (MTX) in patients with moderate to severe RA who didn’t respond well to conventional antirheumatic drugs. Main findings. UPA + MTX would entail a minimal increase in costs for the healthcare system in Argentina, potentially making this effective treatment option more accessible to patients with RA. Access to this treatment can improve the outcome of patients with RA. Public health implications. In resource-constrained settings such as Argentina, providing evidence-based cost estimates can help healthcare managers allocate resources efficiently while improving patient outcomes. This study provides evidence to inform healthcare policies and decisions regarding the inclusion of UPA + MTX in treatment guidelines or formularies for RA management.

Expenditure of biological drugs for rheumatoid arthritis treatment in the Brazilian public health system

OBJECTIVE

This work aims to analyze the quantity and expenses related to biological drugs used for the treatment of rheumatoid arthritis (RA) in outpatient public care within the Brazilian Unified Health System (SUS).

METHODS

It is a cross-sectional descriptive study based on secondary data from a historical series, referring to the purchase, volume, and the number of patients treated with different biological drugs (infliximabe, etanercept, adalimumab, rituximab, abatacept, tocilizumab, golimumab, and certolizumab pegol) for RA treatment in outpatient care from 2012 to 2017. The data were extracted from the SUS Outpatient Information System database-SIA/SUS and included ten drugs used for RA treatment. The study assessed the quantity and expenditure of these drugs, the number of RA patients treated, and the expenditure by RA subtypes. The National Broad Consumer Price Index was used to adjust the expenditures for December 2017.

RESULTS

The Ministry of Health allocated approximately $500 million to provide about 2 million units of biological drugs for RA patients from 2012 to 2017. The supply of adalimumab 40 mg and etanercept 50 mg accounted for 68.3% of the total expenditure. The subtypes "other rheumatoid arthritis with rheumatoid factor" (ICD-10 M05.8), "rheumatoid arthritis without rheumatoid factor" (ICD-10 M06.0), and "Felty's syndrome" (M05. 0) represented 84.5% of the total expenditures. The proportion of patients treated with biological drugs increased by 33.0%. There was a significant 83.0% increase in the number of patients using biological drugs compared to the overall number of RA patients treated during the study period.

CONCLUSIONS

The results obtained allow us to draw a more recent profile of expenditure on RA treatment and indicate trends in the use of biological drugs for this condition, generating data that can support management decisions in public health policies.

Intestinal complications in patients with Crohn’s disease in the Brazilian public healthcare system between 2011 and 2020

BACKGROUND

This is a secondary database study using the Brazilian public healthcare system database.

AIM

To describe intestinal complications (ICs) of patients in the Brazilian public healthcare system with Crohn’s disease (CD) who initiated and either only received conventional therapy (CVT) or also initiated anti-tumor necrosis factor (anti-TNF) therapy between 2011 and 2020.

METHODS

This study included patients with CD [international classification of diseases – 10^th revision (ICD-10): K50.0, K50.1, or K50.8] (age: ≥ 18 years) with at least one claim of CVT (sulfasalazine, azathioprine, mesalazine, or methotrexate). IC was defined as a CD-related hospitalization, pre-defined procedure codes (from rectum or intestinal surgery groups), and/or associated disease (pre-defined ICD-10 codes), and overall (one or more type of ICs).

RESULTS

In the 16809 patients with CD that met the inclusion criteria, the mean follow-up duration was 4.44 (2.37) years. In total, 14697 claims of ICs were found from 4633 patients. Over the 1- and 5-year of follow-up, 8.3% and 8.2% of the patients with CD, respectively, presented at least one IC, of which fistula (31%) and fistulotomy (48%) were the most commonly reported. The overall incidence rate (95%CI) of ICs was 6.8 (6.5–7.04) per 100 patient years for patients using only-CVT, and 9.2 (8.8–9.6) for patients with evidence of anti-TNF therapy.

CONCLUSION

The outcomes highlighted an important and constant rate of ICs over time in all the CD populations assessed, especially in patients exposed to anti-TNF therapy. This outcome revealed insights into the real-world treatment and complications relevant to patients with CD and highlights that this disease remains a concern that may require additional treatment strategies in the Brazilian public healthcare system.

IBD barriers across the continents: a continent-specific analysis: Latin America

Latin America (LATAM) is a large region comprising 47 countries and territories. Each one carries a different cultural and historical background, diverse political systems, and a particular approach to healthcare management. There is a lack of high-quality data on the epidemiology of inflammatory bowel diseases (IBD) in this region, including broad and detailed information about the penetration of biological and advanced therapies as treatment strategies. From an IBD perspective, patients experience, in general, fragmentations and inequities in the healthcare systems, with different and usually delayed access to qualified health services. This review explores the barriers to accessing IBD care throughout LATAM. The authors compiled data from multiple sources, such as studies focusing on epidemiology, biological penetration, and surgical rates. In addition, overall access to IBD treatments was assessed through a questionnaire distributed to physicians in LATAM via email and direct messaging to capture local perspectives.

Safety of biological therapy in patients with rheumatoid arthritis in administrative health databases: A systematic review and meta-analysis

Background: Rheumatoid arthritis (RA) is a systemic inflammatory disease that affects the synovial fluid of joints, tendons, and some extra-articular sites. Biologic agents have been highly effective and are comparable in reducing RA symptoms, slowing disease progression, and improving physical function; however, concerns have been raised about the risks of several potential adverse effects. Thus, this study aimed to assess the safety of biological therapy in patients with rheumatoid arthritis in observational studies using administrative health databases. Methods: PubMed, Embase, Lilacs, Ovid, Scopus, and Web of Science were searched from inception to 21 October 2021. The analysis was divided into five groups: tumor necrosis factor inhibitors (TNFi) versus non-TNFi; TNFi versus csDMARDs; bDMARDs versus csDMARDs; abatacept versus bDMARDs; and TNFi versus Janus kinase inhibitors (JAKi). The adverse events were cancer, cardiovascular events, infection, herpes zoster, tuberculosis, and death. The methodological quality of the studies was assessed by the Newcastle-Ottawa Scale. A random-effects model estimated risk ratios with 95% confidence intervals. Results: Thirty-one studies were eligible for inclusion in the present systematic review, published from 2014 to 2021. A total of 1,039,398 RA patients were assessed. The 31 studies evaluated eleven different biological drugs. No significant differences were found regarding safety between TNFi versus non-TNFi (RR 1.08; 95% CI 0.92-1.28; p < 0.01; I2 = 93.0%), TNFi versus csDMARDs (RR 0.91; 95% CI 0.75-1.10; p < 0.01; I2 = 87.0%), bDMARDs versus csDMARDs (RR 0.99; 95% CI 0.82-1.20; p < 0.01; I2 = 93.0%), abatacept versus bDMARDs (RR 0.80; 95% CI 0.54-1.18; p < 0.01; I2 = 90.0%), and TNFi versus JAKi (RR 3.54; 95% CI 0.30-42.09; p = 0.01; I2 = 81.0%). In the subgroup analysis, among studies comparing abatacept to TNFi, a lower risk of cardiovascular events was associated with abatacept (RR 0.37; 95% CI 0.24-0.55). Conclusion: Our results do not suggest an increased risk of adverse events associated with biological therapy in treating RA patients, indicating a lower risk of cardiovascular events with abatacept than TNFi. However, these findings must be interpreted with caution given the limitations of this study and the low/very low certainty of the evidence.

Impact of clinical and psychological factors associated with depression in patients with rheumatoid arthritis: comparative study between Germany and Brazil

OBJECTIVE

To investigate the prevalence of depressive symptoms and its association with clinical and psychological factors in patients with rheumatoid arthritis (RA) in Germany and in Brazil.

METHOD

A convenience sample of 267 RA patients, 176 from Germany (age 62.4 ± 12.3 years) and 91 from Brazil (age 56.3 ± 12.6 years), was used in this cross-sectional study. The following questionnaires were used: Beck Depression Inventory (BDI), painDETECT test, Perceived Stress Questionnaire, fatigue questionnaire (FACIT), Health Assessment Questionnaire Disability Index (HAQ-DI), and the SF-36 questionnaires (Short-Form 36 Health Survey). Disease activity score (DAS 28-CRP) and visual analogue scale (VAS) for pain were also evaluated. Statistical analysis is based on comparison of means and proportions. Statistical significance for non-normal data was evaluated by non-parametrical tests.

RESULTS

Depressive symptoms were more prevalent in the Brazilian sample (44% vs 22.9%, p = 0.025). Compared to German patients, the Brazilian ones also experienced more pain (current pain status on VAS: 4.67 ± 3.4 vs 3.67 ± 2.31 respectively, p < 0.01), were physically more limited (1.89 ± 1.85 vs 1.01 ± 0.75, p = 0.012), and had higher C-reactive protein levels (7.78 ± 18.3 vs 5.82 ± 10.45, p = 0.028). Despite receiving a more intensive treatment, German patients presented similar disease activity when compared to Brazilian patients (DAS28-CRP: Brazil 3.4 ± 1.5 vs Germany 3.3 ± 1.3, p = 0.307).

CONCLUSION

Depressive symptoms are frequent in RA patients from different countries and interact with psychological disorders and the experience of pain. They contribute negatively to their well-being suggesting the need for psychoeducational strategies. Key Points • New psychoeducational strategies for RA management.• Higher inflammation marker in rheumatoid arthritis patients is associated with depression.• Medical treatment in RA influences depressive symptoms.• Depressive symptoms are dependent on population group.• High disease activity is related to depression.

Beneficio económico de los ensayos clínicos controlados patrocinados: El gasto evitable en medicamentos para el tratamiento de la artritis reumatoidea

OBJECTIVES

To estimate the following: (1) the avoidable cost of biologic (bDMARDs) and conventional synthetic Rheumatoid Arthritis (RA) modifying antirheumatic drugs (csDMARDs) during controlled clinical trials (CCTs), their extension period, and for bDMARDs in post study drug programs; and (2) to evaluate the impact on health insurances.

METHODS

We analyzed 13 CCTs (233 patients) that evaluated bDMARDs. Avoidable cost was what the health insurance should have paid if the patient had not received the medication from the CCT sponsor and was estimated with a micro-costing approach (bottom-up method). Results were expressed as mean ± standard deviation (SD) or percentages. Approved by the Ethics Committee.

RESULTS

Mean age was 50.62 SD 11.8 years, 84% were women, 72% (n = 166) had health insurance. The mean annual cost of bDMARDs was US$ 30 567.40 while the cost for csDMARDs was US$ 104.90 during the CCTs. The mean annual cost in extension periods and post study drug programs for bDMARDs was US$ 36 016.20 and for csDMARs during the extension period was US$ 81.70. The avoidable cost for public health insurances exceeded one million dollars per year.

CONCLUSION

This work describes for the first time in Argentina the significant economic benefit that may represent for RA patients' health insurances the participation in CCTs with bDMARDs. It shows that during the execution of the CCT, its extension periods, or post study access programs, while medication provision is guaranteed, the economic burden imposed by the treatment of the RA is relieved.
