Krstic M, Devaud JC, Sadeghipour F, Marti J. Does the introduction of an infliximab biosimilar always result in savings for hospitals? A descriptive study using real-world data. HEALTH ECONOMICS REVIEW 2024; 14:31.

Abstract
BACKGROUND Biosimilars are biologic drugs that have the potential to increase the efficiency of healthcare spending and curb drug-related cost increases. However, their introduction into hospital formularies through initiatives such as non-medical switching must be carefully orchestrated so as not to cause treatment discontinuation or result in increased health resource utilization, such as additional visits or laboratory tests, among others. This retrospective cohort study aims to assess the impact of the introduction of CT-P13 on the healthcare expenditures of patients who were treated with originator infliximab or CT-P13. METHODS Gastroenterology, immunoallergology and rheumatology patients treated between September 2017 and December 2020 at a university hospital in Western Switzerland were included and divided into seven cohorts, based on their treatment pathway (i.e., use and discontinuation of CT-P13 and/or originator infliximab). Costs in Swiss francs were obtained from the hospital's cost accounting department and length of stay was extracted from inpatient records. Comparisons of costs and length of stay between cohorts were calculated by bootstrapping. RESULTS Sixty immunoallergology, 84 rheumatology and 114 gastroenterology patients were included. Inpatient and outpatient costs averaged (sd) CHF 1,611 (1,020) per hospital day and CHF 4,991 (6,931) per infusion, respectively. The mean (sd) length of stay was 20 (28) days. Although immunoallergology and rheumatology patients had higher average costs than gastroenterology patients, differences in costs and length of stay were not formally explained by treatment pathway. Differences in health resource utilization were marginal. CONCLUSIONS The introduction of CT-P13 and the disruption of patient treatment management were not associated with differences in average outpatient and inpatient costs and length of stay, in contrast to the results reported in the rest of the literature. Future research should focus on the cost-effectiveness of non-medical switching policies and the potential benefits for patients.

Abstract
OBJECTIVES The objective was to assess the adherence, persistence, and costs of bDMARDs through a multicentre study of nine Italian hospital pharmacies. METHODS The drugs analysed were Abatacept, Adalimumab, Certolizumab, Etanercept, Golimumab and Tocilizumab.Adult subjects with Rheumatoid Arthritis were considered in the analysis.In this study, we calculated the following metrics: Adherence to treatment was evaluated as dose-intensity, which is the ratio between the amount of medication received and probably taken by the patient at home (Received Daily Dose, RDD) and the amount prescribed by the clinician (Prescribed Daily Dose, PDD). Persistence was calculated as the number of days between the first and last dispensing of the same drug. Lastly, costs were assessed based on persistence to treatment and normalized for adherence. RESULTS Adherence to treatment was found to be above 0.8 for all drugs studied. The median persistence for a 5-year treatment period was 1.4 years for Abatacept, 1.7 years for Adalimumab, 1.8 years for Certolizumab, 1.4 years for Etanercept, 1.3 years for Golimumab, and 1.6 years for Tocilizumab. CONCLUSIONS This multicentre retrospective observational study of bDMARDs used in the treatment of RA showed that, for all the drugs studied, there was no problem with adherence to treatment but rather a difficulty in maintaining treatment with the same drug over time.

Abstract
To date, numerous biosimilars are available in Europe and the practice of switching between originator and biosimilar or between two different biosimilars has become very widespread. However, multiple switching has not been adequately studied. The aim of this study is to conduct a literature review to assess the effectiveness and safety of multiple switches. All PubMed articles involving multiple switches from originator to biosimilars or between different biosimilars were considered. The relevant data on effectiveness and safety were extracted from these studies and the results were reported through descriptive analysis. Fifteen studies were considered, of which 11 were observational and 4 clinical trials. Inflammatory bowel disease and psoriasis were the most studied diseases. All studies reported that the effectiveness and safety in patients whose treatment involved multiple switches, was comparable to patients whose treatment involved a single or no switch at all. Some therapeutic fields such as oncology and renal insufficiency were not represented at all in the multiple switch studies. New evidence is desperately needed and should be made available to the scientific community and decision-makers.

Abstract
INTRODUCTION To examine the prevalence rates of biosimilar discontinuation and switchback to the originator tumor necrosis factor alpha (TNF) inhibitors following non-medical switch (NMS) in patients. METHODS Real-world studies reporting biosimilar discontinuation and switchback rates following NMS published between January 2012 and August 2018 were identified through a systematic literature review. A meta-analysis estimated the annualized discontinuation and switchback rates. A subsequent meta-analysis assessed annualized incremental discontinuation rate among studies reporting both discontinuation rates in patients who underwent an NMS (switchers) and patients who remained on originators (non-switchers). RESULTS A total of 66 publications were identified: 31 in gastroenterology, 32 in rheumatology, and 3 in both. Half of the studies reported switchback rates; only 9 studies reported discontinuation rates for both switchers and non-switchers. Across studies, the mean/range sample size of the NMS patient population was 136/9-1641; mean/range follow-up was 10/3-24 months. Annualized biosimilar discontinuation rate was 21% (95% confidence interval [CI] 18%, 25%). Switchback rate was 14% (95% CI 10%, 17%) among all NMS patients and 62% (95% CI 44%, 80%) among discontinuers. The mean/range sample size of switchers and non-switchers was 344/89-1621 and 768/19-2870, respectively; mean/range follow-up was 11/6-18 and 12/6-8 months, respectively. Annualized incremental biosimilar discontinuation rate was 18% (95% CI 4%, 31%). CONCLUSION Biosimilar discontinuation was found to be prevalent among patients who underwent an NMS from an originator TNF inhibitor to its biosimilar(s) in the real world. In addition, switchback to the originator TNF inhibitors was common following biosimilar discontinuation. Careful consideration is necessary when switching patients already on an originator TNF inhibitor to its biosimilar(s). Main limitations included the heterogeneity of the studies and the limited comparability of the data.

Abstract
Background Drug coverage policies that incentivize switching patients from originator to biosimilar products may result in significant health care savings. Our study aimed to detect early impacts on health services utilization following a mandated switch from originator to biosimilar etanercept in British Columbia (BC), Canada. Methods We conducted a prospective, population-based cohort study using linked administrative health data from BC (2010–2020). The policy cohort consisted of patients with inflammatory arthritis who used originator etanercept in 2019, prior to BC’s Biosimilars Initiative switching policy. Three historical cohorts included patients with inflammatory arthritis who used originator etanercept in the years 2016, 2017, and 2018. We compared the daily cumulative incidences of drug refills and outpatient and inpatient services between the policy and historical cohorts. A likelihood ratio sustained (≥ 31 days) at 7.1 or higher compared with the null hypothesis was chosen a priori as a threshold for a potential impact of the policy. Results Each cohort contained between 1694 and 1963 patients. We detected several potential impacts: 1) a transient increase in etanercept refills between months three and eight (cumulative incidence difference of + 3.0%); 2) an anticipated increase in visits to physicians of any specialty between months three and eight (+ 2.6%); and 3) an anticipated increase in visits to a rheumatologist from the end of month three onwards (+ 12.8%). The policy had no impact on incidences of switching to a different biologic antirheumatic drug, visits to emergency departments, or admissions to hospitals. Conclusions Only transient and/or anticipated increases in drug refills and physician visits were observed during the study period. Additional research on clinical outcomes is recommended to strengthen the evidence that no long-term unintended negative health impacts are associated with BC’s Biosimilars Initiative [switching policy].

Abstract
BACKGROUND In 2019, British Columbia's public drug plan, PharmaCare, was the first in Canada to implement a nonmedical switching policy from originator infliximab to its biosimilar, for patients with inflammatory arthritis or psoriasis. We aimed to detect signals of impact on health services utilization during the first year of policy implementation and to provide early data to policy-makers. METHODS We constructed cohorts of users of originator infliximab: 3 historical cohorts (2016-2018) and 1 policy cohort (2019). We extracted data from BC Ministry of Health databases from 2015 to 2020, as we followed each cohort for 365 days from May 27 of each cohort's respective year. We excluded patients with gastrointestinal conditions and those not covered by PharmaCare. We examined the cumulative incidence of infliximab prescription refills, switching to other biologic drugs and use of additional health services. A log-likelihood ratio of 1.96 compared with the null hypothesis was used as the threshold for differences between the policy cohort and the historical cohorts. RESULTS The study included a total of 572 unique patients: 520 in the 2016 historical cohort, 461 in the 2017 historical cohort, 423 in the 2018 historical cohort and 377 in the policy cohort (with some patients included in multiple cohorts; 335 [58.6%] were included in all 4 cohorts). During months 8 and 9 of follow-up, a transient signal was observed in infliximab refills (7.2% decrease in refilling infliximab for the fourth time for the policy cohort, log-likelihood ratio > 1.96). An anticipated increase in visits to specialists was observed from month 4 forward (15.0%, log-likelihood ratio > 1.96). No signal was observed for increased use of other health services (log-likelihood ratio < 1.96). INTERPRETATION Early monitoring did not detect signals of negative impacts on health services use during the first year of the policy. Detailed, longer-term cohort studies and hypothesis-testing methods could provide additional assurance about the safety of the policy.

Abstract
INTRODUCTION To save costs to the healthcare system, forced non-medical switch (NMS) policies that cut drug coverage for originator biologics and fund only less expensive biosimilars are being implemented. However, costs related to the impact of NMS on healthcare resource utilization (HCRU) must also be considered. This study aims to summarize the evidence on the economic impact of an originator-to-biosimilar NMS. METHODS A systematic literature review (SLR) was conducted. Publications reporting on HCRU or costs associated with originator-to-biosimilar NMS in the real-world setting were searched in MEDLINE and EMBASE from January 2008 to February 2020. In addition to hand searching the reference lists of relevant publications and SLRs, key conference websites, PubMed, and various government sites were also searched for the 2 years preceding the search (2018-2020). RESULTS A total of 1845 citations were identified, of which 49 were retained for data extraction. Most studies reporting on the HCRU associated with NMS reported on post-NMS HCRU alone without a comparison pre-NMS. However, four studies described a difference in HCRU (i.e., investigations pre- vs post-switch or between non-switchers vs switchers), all of which reported a relative increase in HCRU, including laboratory testing, imaging, medical visits, and hospitalizations, amongst patients who underwent an originator-to-biosimilar NMS. Most studies reporting on the costs associated with NMS reported significant savings following NMS on the basis of drug costs alone. However, four studies specifically reporting on the difference of costs following originator-to-biosimilar NMS all demonstrated an increase in HCRU-related costs associated with NMS (increase in HCRU-related costs of 4-37% or 148-2234 2020 Canadian dollars). CONCLUSION Amongst the studies that reported on the difference in HCRU pre- vs post-switch or between non-switchers and switchers, all showed an increase in HCRU and related costs associated with NMS, suggesting that the expected overall savings due to less costly drug prices may be reduced as a result of an increase in HCRU and its associated costs post-switch. Nevertheless, more real-world studies that include NMS-related healthcare costs in addition to drug costs are needed.

Abstract
Over time, clinicians have become increasingly comfortable embracing the prescription of biosimilars-highly similar versions of innovator or reference biological agents-for their patients with inflammatory diseases. Although a switch from a reference product to a licensed biosimilar version (or vice versa) is a medical decision robustly supported by the stepwise accumulation of clinical trial evidence concerning comparable safety, immunogenicity, and efficacy between these products, a switch from one biosimilar to another biosimilar of the same reference product, or a cross-switch, is not. Similarity among biosimilars of a reference product is not a regulatory agency concern and therefore is unlikely to be investigated in randomized controlled trials in the foreseeable future. Yet in clinical practice, across a diverse range of patients, the option to cross-switch from one biosimilar to another can and does arise for valid reasons such as convenience or tolerability issues, or driven by third parties (e.g., payers). In the absence of clinical trial data, clinicians must attempt to objectively evaluate the emerging real-world cross-switching evidence within the context of what is known about the science underpinning a designation of biosimilar. That knowledge then needs to be integrated with what clinicians know about their patients and their disease on a case-by-case basis. This review aims to consolidate relevant emerging real-world data and other key information about biosimilar-to-biosimilar cross-switching for prescribing clinicians. In the absence of clear clinical guidelines addressing this topic at present, this review may serve to facilitate discretionary and educated treatment decision making.

Abstract
The biosimilar concept is now well established. Clinical data accumulated pre- and post-approval have supported biosimilar uptake, in turn stimulating competition in the biologics market and increasing patient access to biologics. Following technological advances, other innovative biologics, such as “biobetters” or “value-added medicines,” are now reaching the market. These innovative biologics differ from the reference product by offering additional clinical or non-clinical benefits. We discuss these innovative biologics with reference to CT-P13, initially available as an intravenous (IV) biosimilar of reference infliximab. A subcutaneous (SC) formulation, CT-P13 SC, has now been developed. Relative to CT-P13 IV, CT-P13 SC offers clinical benefits in terms of pharmacokinetics, with comparable efficacy, safety, and immunogenicity, as well as increased convenience for patients and reduced demands on healthcare system resources. As was once the case for biosimilars, nomenclature and regulatory pathways for innovative biologics require clarification to support their uptake and ultimately benefit patients.

Abstract
PURPOSE We explored changes in health services utilization associated with the Biosimilars Initiative introduced in British Columbia on May 27, 2019. To maintain drug coverage, the policy requires users of originator infliximab or etanercept to transition to biosimilar versions. We present a three-month interim analysis of this initiative. METHODS We conducted a rapid monitoring analysis to evaluate changes in health services utilization three months after the policy was introduced compared with a three-year period before the policy's introduction. Using the administrative claims data of the British Columbia Ministry of Health, we assembled three historical cohorts and one policy cohort of users of each originator drug (8 cohorts in total). Cumulative incidences of medication refills, switching, and visits to physicians were the outcome measures used to compare policy and historical cohorts. Likelihood ratios were used to quantify statistical differences between each policy cohort and its respective historical controls. Likelihood ratios above 7.1 were considered statistically significant. RESULTS The four infliximab cohorts included 436 patients on average, mean age 56 to 59, 53% to 55% females. The four etanercept cohorts included 1826 patients on average, mean age 57 to 58, 60% to 63% females. Three months after the policy's introduction, 21% of patients treated in the policy cohorts transitioned to the biosimilar versions. Health services utilization in the policy cohorts were consistent with the historical cohorts. CONCLUSIONS An increase in visits to physicians was expected but not detected in the first three months of the Biosimilars Initiative. The impacts of the policy will continue to be monitored.

Impact of a medical interview on the decision to switch from originator infliximab to its biosimilar in patients with inflammatory bowel disease. Dig Liver Dis 2020; 52:281-288. [PMID: 31648920 DOI: 10.1016/j.dld.2019.09.012] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2019] [Revised: 09/05/2019] [Accepted: 09/09/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND To lighten the burden on health-care spending, switching from the infliximab originator to a biosimilar in patients with inflammatory bowel disease (IBD) is advocated. However, the uptake of biosimilars lacks initiatives aimed at educating patients. AIMS To explore the impact of a gastroenterologist's interview on IBD patients' acceptance for switching from infliximab bio-originator Remicade® to its biosimilar CT-P13 Inflectra®. METHODS After the interview of 138 included patients, 120 properly responded to a self-administered questionnaire to collect consent about the switch and relevant data. French national IBD patients' association (Association François Aupetit) provided an information sheet on biosimilars. RESULTS 93 (67.0%) out of 138 and 82 (68.3%) out of 120 patients switched treatment. 114 (79.8%) had never heard about biosimilars. Paradoxically, having heard about biosimilars was associated with a poorer chance to switch (Odds Ratio OR [95% CI] = 0.13 [0.02-0.72]). On the contrary, the more satisfied about generics, the more patients accepted the switch (OR [95% CI] = 1.31 [1.01-1.69]). There were 1.47 (Relative Risk RR [95% CI] = 1.47 [1.07-2.01]) times more chance to agree to the switch if the interview modified the patient's opinion on biosimilars. CONCLUSION This study confirms that an organized information provided to the patient is a contributive way to enhance patient's acceptance of biosimilars in IBD.

Abstract
Biologics have transformed the treatment of immune-mediated inflammatory diseases such as rheumatoid arthritis (RA) and inflammatory bowel disease (IBD). Biosimilars-biologic medicines with no clinically meaningful differences in safety or efficacy from licensed originators-can stimulate market competition and have the potential to expand patient access to biologics within the parameters of treatment recommendations. However, maximizing the benefits of biosimilars requires cooperation between multiple stakeholders. Regulators and developers should collaborate to ensure biosimilars reach patients rapidly without compromising stringent quality, safety, or efficacy standards. Pharmacoeconomic evaluations and payer policies should be updated following biosimilar market entry, minimizing the risk of imposing nonmedical barriers to biologic treatment. In RA, disparities between treatment guidelines and national reimbursement criteria could be addressed to ensure more uniform patient access to biologics and enable rheumatologists to effectively implement treat-to-target strategies. In IBD, the cost-effectiveness of biologic treatment earlier in the disease course is likely to improve when biosimilars are incorporated into pharmacoeconomic analyses. Patient understanding of biosimilars is crucial for treatment success and avoiding nocebo effects. Full understanding of biosimilars by physicians and carefully considered communication strategies can help support patients initiating or switching to biosimilars. Developers must operate efficiently to be sustainable, without undermining product quality, the reliability of the supply chain, or pharmacovigilance. Developers should also facilitate information sharing to meet the needs of other stakeholders. Such collaboration will help to ensure a sustainable future for both the biosimilar market and healthcare systems, supporting the availability of effective treatments for patients.

Simoens S, Cheung R. Tendering and biosimilars: what role for value-added services? JOURNAL OF MARKET ACCESS & HEALTH POLICY 2020; 8:1705120. [PMID: 32002174 PMCID: PMC6968494 DOI: 10.1080/20016689.2019.1705120] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Revised: 11/06/2019] [Accepted: 11/19/2019] [Indexed: 05/12/2023]
Abstract
Background: Access to biologic medicines (including biosimilars) across Europe is largely governed by a process of tendering conducted by health authorities. Over-reliance on treatment costs in awarding tenders has the potential to hinder competition and undermine the long-term sustainability of biosimilars. Objective: To assess the extent and impact of consideration of 'value-added services' (VAS) in tendering for biosimilars, we conducted a narrative review of published literature. Results: Findings from survey-based publications indicated that tendering practices for biosimilars are widely used, with cost being the main determinant of success and little detail being available on other criteria where these apply. Criteria (of therapeutic and technical interest) beyond price were included in one tendering specification for infliximab (originator and biosimilars), while a separate tender for the same product included VAS in the form of therapeutic drug monitoring, measurement of antibodies and calprotectin. Conclusions: Published evidence concerning inclusion of VAS in tendering for biosimilars is lacking. Development and implementation of standardized criteria and methods of assessment for tenders may avoid manufacturers facing segmented markets, encourage competition and the longer-term sustainability of biosimilars, and realize the healthcare system and patient benefits these treatments can bring.

Abstract
Objectives In year 2016, Danish national guidelines included a mandatory switch of patients with inflammatory rheumatic diseases treated with originator etanercept (ETA) to biosimilar SB4 in routine care. We aimed to explore if switching lead to increased healthcare utilisation and costs. Methods Observational cohort study. Adult patients who switched from ETA to SB4 were identified in the Danish nationwide DANBIO registry. In the National Patient Registry, we identified health utilisation (hospital admissions/hospital days/outpatient visits/prescription medication use) and comorbidities. Estimation of health utilisation included average use and costs 1 year before/after switch, changes after the switch, and whether patient characteristics affected changes. Analyses were by adjusted two-step gamma distributed regression models, and for changes over time a generalized estimation equations (GEE) model was applied. Impact of comorbidities was explored as interaction terms in the model. Medication costs of ETA and SB4 were not included in model. Results 1620 patients were included (mean age 55 years (SD 14.7), 40% male). Costs before and after switching were mainly driven by outpatient visits (67%/72% of all costs). Monthly fluctuations of costs were similar before/after switch. After switching, use (8%) and costs (7%) of outpatient services increased, whereas costs of admissions (55%) and medication (5%) decreased. Patients with longer ETA treatment duration had an increase in use and costs of healthcare resources, whereas gender and comorbidities had no impact. Higher age was associated with an increase in costs of inpatient services. Conclusion We demonstrated no obvious changes in overall use and costs of healthcare services following switch from originator to biosimilar etanercept.

Economic Impact of Non-Medical Switching from Originator Biologics to Biosimilars: A Systematic Literature Review. Adv Ther 2019; 36:1851-1877.

Abstract
Introduction A systematic literature review was conducted to review and summarize the economic impact of non-medical switching (NMS) from biologic originators to their biosimilars (i.e., switching a patient’s medication for reasons irrelevant to the patient’s health). Methods English publications reporting healthcare resource utilization (HRU) or costs associated with biosimilar NMS were searched in PubMed and EMBASE over the past 10 years and from selected scientific conferences over the past 3 years, along with gray literature for all biologics with an approved biosimilar (e.g., tumor-necrosis factor inhibitors, erythropoiesis-stimulating agents, insulin and hormone therapies). Results A total of 1311 publications were retrieved, where 54 studies met the selection criteria. Seventeen studies reported increased real-world HRU or costs related to biosimilar NMS, e.g., higher rates of surgery (11%), steroid use (13%) and biosimilar dose escalating (6–35.4%). Among the studies that the estimated cost impact associated with NMS, 33 reported drug costs reduction, 12 reported healthcare costs post-NMS without a detailed breakdown, and 5 reported NMS setup and managing costs. Cost estimation/simulation studies demonstrated the cost reduction associated with NMS. However, variation across studies was substantial because of heterogeneity in study designs and assumptions (e.g., disease areas, scenarios of drug price discount rates, cost components, population size, study period, etc.). Conclusion Real-world studies reporting the economic impact of biosimilar NMS separately from drug costs are emerging, and those that reported such results found increased HRU in patients with biosimilar NMS. Studies of cost estimation have been largely limited to drug prices. Comprehensive evaluation of the economic impact of NMS should incorporate all important elements of healthcare service needs such as drug price, biologic rebates, HRU, NMS program setup, administration and monitoring costs.

Abstract
Introduction: The expiry of patents for biologics has led to the introduction of biosimilars for the treatment of immune-mediated inflammatory diseases (IMIDs). These treatment alternatives may allow earlier and wider access to appropriate therapy for patients without increasing the economic burden on health-care systems. Prescription of biosimilars to treatment-naïve patients is well accepted; however, additional considerations must be taken into account when switching clinically stable patients from reference products to biosimilars. Area covered: We discuss the current considerations related to switching from reference products to biosimilars from a physician and patient perspective. We review the clinical data and real-life experience on switching patients with IMIDs, present the position of the relevant medical societies, and discuss the importance of patient-physician communication and need for shared decision-making. Expert opinion: The introduction of biosimilars provides an opportunity to expand access to treatment for patients with IMIDs across Europe and support the financial sustainability of health-care systems. We anticipate that as the real-world evidence base grows, confirming the results of clinical trials, there will be a corresponding increase in physician and patient acceptance, not only to initiating treatment with a biosimilar, but also to switching medication from a reference product to a biosimilar.
