An online survey among US patients with immune-mediated conditions: Attitudes about biosimilars. | LitMetric

AI Article Synopsis

  • A survey conducted by WebMD assessed the attitudes of US patients with rheumatoid arthritis, psoriasis, or inflammatory bowel disease towards biosimilars, revealing that 66% were unaware of them before the survey.
  • Among the participants, 44% were on biologics, and of those, 43% expressed willingness to switch to a biosimilar after learning about it, though many had concerns regarding side effects and long-term safety.
  • The findings showed that while awareness of biosimilars was low, most patients showed openness to the idea of switching to them, particularly if their insurance required it, indicating a clear interest in understanding biosimilars better.

Article Abstract

Few surveys about biosimilars have been conducted among US patients. To evaluate attitudes about biosimilars among patients with rheumatoid arthritis (RA), psoriasis and/or psoriatic arthritis (PsO/A), and/or inflammatory bowel disease (IBD). WebMD, LLC fielded a 16-item online survey to members of the US Dynata consumer panel meeting these criteria: aged 18 years or older; self-reported specialist diagnosis of RA, PsO/A, or IBD of at least 1 year; and not currently receiving an infliximab biosimilar. A quota of 500 was set, stratified by region and condition. The survey was exempt by the institutional review board, exploratory, and not registered. Overall, 44% (n = 221) of patients were on a biologic; 56% (n = 279) were not on a biologic (40% [n = 199] were biologic naive and 16% [n = 80] used biologics in the past). Among all patients, 66% were unaware of biosimilars and 24% were aware (10% unsure). After being shown the US Food and Drug Administration definition of a biosimilar, main concerns were side effects (59%), long-term safety (50%), and not knowing a lot (46%). Among current users, 43% would switch to a biosimilar and 26% would not (32% unsure). Of those unwilling to switch, 51% were concerned about side effects, 42% about financial support, and 40% about efficacy. When those not on a biologic were asked if their doctor prescribed an original anti-tumor necrosis factor α but their insurance required its biosimilar, 49% would switch and 8% would not (43% unsure). 51% of patients surveyed thought pharmacist-level substitution of an interchangeable biosimilar was acceptable with notification. Survey findings were consistent among the RA, PsO/A, and IBD subgroups. Although two-thirds of patients surveyed were unaware of biosimilars, the majority were potentially receptive to biosimilar treatment after being provided with the definition of a biosimilar. Patients expressed a desire to know more about biosimilars in general, how they compare with original biologics, their benefits, and cost. This study was funded by Boehringer Ingelheim Pharmaceuticals Inc. (BIPI). WebMD, LLC, fielded the survey. BIPI was given the opportunity to review the article for medical and scientific accuracy and intellectual property considerations.
