RESUMEN

OBJECTIVES: The safety, efficacy, and cost savings associated with biosimilar medications are well established. However, a lack of pediatric data exists surrounding clinical outcomes when switching from an originator to a biosimilar. Our primary aim is to evaluate clinical outcomes following a nonmedical switch from the infliximab originator to a biosimilar in children and young adults with inflammatory bowel disease (IBD). Our secondary aim is to estimate cost savings associated with this switch. METHODS: A quality improvement project was implemented to establish safe switching protocols, then those patients who underwent a nonmedical switch from the infliximab originator to the biosimilar were retrospectively reviewed. Demographic data, physician global assessments (PGAs), and laboratory values were recorded 1 year pre- and post-switch. Continuation rates on the biosimilar were reported at 6 and 12 months. Cost savings were estimated using two different pricing models. RESULTS: Fifty-three patients underwent a nonmedical switch. Laboratory values including inflammatory markers, infliximab levels, and PGA scores remained similar when assessed pre- and post-switch. No infusion reactions or antidrug antibody development occurred. Two patients reported psoriasis-like rashes. Five patients switched back to the originator during the study period. There were 379 biosimilar infusions completed with an estimated total cost savings of $11,260 (average sales price) and $566,223 (wholesale acquisition cost). CONCLUSIONS: Clinical remission rates, inflammatory laboratory markers, serious adverse events, infliximab levels, and antidrug antibodies remained similar after a one-time nonmedical switch to an infliximab biosimilar. Nonmedical switching to biosimilars resulted in significant cost savings.

RESUMEN

BACKGROUND: Biosimilars are biological agents that have been demonstrated to have similar safety and efficacy profiles as the originator. The objective of this study was to evaluate the perspectives of pediatric gastroenterologists in the United States (U.S.) toward biosimilar use and to explore factors that impact their comfort level with prescribing infliximab biosimilars. METHODS: A cross-sectional survey was developed and distributed to pediatric gastroenterology physicians from the U.S. via a listserv (Pediatric gastroenterology Bulletin Board). Respondent's demographics were recorded. Using a 6-point Likert scale, the survey assessed the respondent's perceptions toward biosimilars and initiating switches from the originator to biosimilar agent along with factors impacting provider's comfort level. Fischer exact tests were used to detect statistically significant differences in responses for hypotheses of interest. RESULTS: One hundred thirty-nine pediatric gastroenterologists completed the online survey (response rate 5.4%). Eighty-seven percent of respondents reported being comfortable prescribing infliximab biosimilars to anti-tumor necrosis factor naive patients, and 69% reported being comfortable doing a one-time switch if the patient was in clinical remission. Factors that negatively impacted a respondent's comfort level included respondents not practicing at an ImproveCareNow (ICN) center and managing less than 50 patients with inflammatory bowel diseases (IBD). CONCLUSIONS: Nearly 90% of pediatric gastroenterologists felt comfortable prescribing an infliximab biosimilar, and 70% felt comfortable with a one-time switch to the biosimilar if the patient was in clinical remission. Involvement in ICN a learning health system and caring for higher numbers of patients with IBD was associated with increased provider comfort with biosimilar use.

RESUMEN

BACKGROUND: Studies assessing adult inflammatory bowel disease (IBD) patient perspectives on biosimilar use revealed that most were unfamiliar with biosimilars and had a negative perception. The objective of this study was to evaluate the perspectives of pediatric patients with IBD and their caregivers regarding biosimilar use and non-medical switches. METHODS: A survey was given to a cross section of patients with IBD ages 11-21 years receiving the intravenous anti-tumor necrosis factor originator and caregivers of patients with IBD ages 3-21 years receiving the originator. Recruitment occurred via mail, during clinic visits, and infusions. Fisher exact tests were used to test for statistically significant differences. RESULTS: Response rate amongst caregivers was 49% (n = 98) and among patients was 35% (n = 67). Sixty-four percent of caregivers and 79% of patients had never heard of biosimilars. There was increased discomfort surrounding the use of biosimilars and switching to a biosimilar amongst caregivers who had previously heard of biosimilars compared to caregivers who had not previously heard of biosimilars ( P < 0.05). Similar concerns were not seen in patient respondents. The length of time on the originator had no effect on patient or caregiver concerns related to biosimilar efficacy, adverse effects, or switches. CONCLUSION: The majority of pediatric patients and caregivers had never heard of biosimilars. Caregivers that had heard of biosimilars before the study were more likely to have a negative perception of them. This study highlights the importance of providing thorough and accurate education to pediatric patients and families regarding the safety and efficacy of biosimilars.

RESUMEN

BACKGROUND: Tumor necrosis factor-alpha inhibitors (anti-TNFs) are a primary treatment for inflammatory bowel disease. Pharmaceutical expenditures and usage of specialty drugs are increasing. In the United States, biosimilars continue to be underutilized, despite opportunities for health care cost savings. Through quality improvement (QI) methodology, we aimed to increase biosimilar utilization among eligible patients initiating intravenous (IV) anti-TNF therapy and describe patient outcomes and associated cost savings. METHODS: Beginning in July 2019, all patients initiating IV anti-TNF therapy were identified and tracked. Using the Institute of Healthcare Improvement Plan-Do-Study-Act cycle, a four-stage problem-solving model used for carrying out change, we trialed interventions to increase biosimilar utilization, including provider, staff, and family education, and utilization of a clinical pharmacist and insurance specialist. Statistical process control charts were used to show improvement over time. Patients' clinical outcome and cost savings were reviewed. RESULTS: Using QI methodology, we increased biosimilar utilization from a baseline of 1% in June 2019 to 96% by February 2021, with sustained improvement. The originator (infliximab) was the insurance company's preferred product for 20 patients (20%). Patient outcomes (IV anti-TNF levels, absence of antidrug antibodies, and physician global assessment) between biosimilars and originators were similar. Estimated cost savings over the project duration were nearly $381,000 (average sales price) and $651,000 (wholesale acquisition cost). CONCLUSIONS: Through QI methodology, we increased biosimilar utilization from 1% to 96% with sustained improvement, without compromising patient outcomes or safety. Estimated cost savings were substantial. Similar methodology could be implemented at other institutions to increase biosimilar utilization and potentially decrease health care costs.
