Why are biosimilars important for patients?
Biosimilars are important because they have an opportunity to provide competition in the market and expand patient access to critical medicines, much like the advent of generic medications more than 35 years ago.
Are there benefits and risks to biosimilars from a patient perspective?
From a patient's perspective, the benefit of a lower-cost biosimilar that has been approved by a regulatory authority in a highly regulated area should be its therapeutic effect with a reduced financial burden.
What is the potential benefit of biosimilars?
BF The main benefit of using biosimilars in patients with inflammatory bowel disease (IBD) is reduced drug acquisition costs. Biosimilars are not generic drugs—they are highly similar to originator biologic agents—but, like generics, biosimilars are less expensive than the originators.
What is the purpose of biosimilars?
The primary purpose of biosimilars is to reduce the healthcare costs associated with the use of biologics and thereby increase access to healthcare. Unlike small molecule generics, the bioequivalence approach is not considered appropriate for the approval of biosimilars.
Are biosimilars as effective as biologics?
Biosimilars are as safe and effective as the original biologic; both are rigorously and thoroughly evaluated by the FDA before approval. Before approving a biosimilar, FDA experts must conclude it is highly similar to and has no clinically meaningful differences from the original biologic.
What is the difference between biosimilars and biologics?
And can it truly replace a biologic? Biologic drugs are large, complex proteins made from living cells through highly complex manufacturing processes. Unlike generic drugs, which are copies of chemical drugs, a biosimilar is a copy of a biologic medicine that is similar, but not identical, to the original medicine.
Why are biosimilars better than generics?
Biosimilars also have significantly higher research and development costs and risks and are more complex to manufacture than small-molecule generics. Biosimilars have the potential to provide additional treatment options at lower cost, but development requires significant investment.
Why are biosimilars better than biologics?
Biologics have revolutionized the prevention, diagnosis, and treatment of cancer, autoimmune conditions, and other diseases. Biosimilars have the potential to enhance treatment accessibility, and with biologic patents beginning to expire, this is an interesting era for the two treatment options.
Why are biosimilars cheaper than biologics?
Biosimilars cost less because the path to their approval is shorter and cheaper. Manufacturers do not need to go through the same number of clinical trials and spend as much on research and development as biologics. That doesn't make them any less safe, though.

How are biosimilars different from generics?
Generic drugs are chemically identical to the original branded drug and, as such, cost significantly less because they don't require much testing. Because biosimilars are made from living organisms, though, and don't contain identical ingredients to their name-brand counterparts, they still require some testing.

Is Sandoz a biosimilar?
With four FDA-ap proved biosimilars and a strong pipeline, Sandoz is well-positioned to lead the US biosimilars industry in development, manufacturing and commercialization.
What is a biosimilar?
The US Public Health Service Act [Section 351 (i)] defines a biosimilar as a “biologic product that is highly similar to the reference biologic, notwithstanding minor differences in clinically inactive components.” 9 (p282) Similarly, the European Union defines a biosimilar medicine as a medicinal product, which is a copy of a biologic product (the reference product) that has already received authorization. 10 Biosimilars are also referred to as follow-on biologicals, similar biotherapeutic products, or subsequent-entry biologics. 11 The term biogenerics is also used occasionally but should be avoided because it may imply that biosimilars are identical to the original compounds, as in the case of generic versions of small-molecule drugs. 10
How do biosimilars affect immunology?
Biologics and biosimilars have the potential to induce antibody responses, which may result in hypersensitivity reactions and other adverse events (AEs) as well as decreased activity. 1 In particular, biosimilars with post-translational modifications are not exactly identical to reference biologics and can trigger an immune response. 36 Immunogenicity may be influenced by patient-, disease-, and/or product-related factors. Patient- and disease-related factors can be derived from original product data. Therefore, evaluations should focus on product-related factors, such as differences in structure between the biosimilar and reference medicine, impurities in preparation of the biosimilar, and changes in storage and/or distribution conditions of the biosimilar. Even seemingly small differences in these factors can affect immunogenicity and pose a risk to patients. Thus, appropriate clinical studies with comprehensive efficacy and safety end points are necessary for each biosimilar, especially because analytic or animal data cannot predict immune response in humans. 1, 61
What are biologics used for?
Biologics are important components of the modern cancer treatment armamentarium 1 and are recommended for the treatment of various types of cancers by National Comprehensive Cancer Network (NCCN) and American Society for Clinical Oncology (ASCO) guidelines because they improve clinical outcomes, including overall survival (OS). 2, 3 Although only 15% of the agents listed in the NCCN Drugs and Biologics Compendium are biologics, they account for the majority of drug-related expenditures in outpatient and hospital settings in the United States. 2 According to a 2011 drug expenditure analysis, biologics accounted for approximately 55% of the total expenditure on antineoplastic drugs in the US health care system; among the biologics, bevacizumab (Avastin; Roche, Basel, Switzerland), rituximab (Rituxan/MabThera; Roche), and trastuzumab (Herceptin; Roche) accounted for more than half of the top 20 antineoplastic expenditures in outpatient clinics. 1, 2, 4, 5 Bevacizumab is approved for the treatment of colorectal, brain, lung, fallopian tube, renal, and other cancers 6; rituximab is approved for the treatment of CD20-positive non-Hodgkin lymphoma and leukemia 7; and trastuzumab is approved for the treatment of human epidermal growth factor receptor 2 (HER2) –positive breast cancer and metastatic gastric and gastroesophageal junction adenocarcinomas. 8 Although effective, biologics are expensive because of the complex manufacturing and development processes, adding to the already high cost associated with cancer treatment.
What are the challenges of biosimilars?
Likewise, generating clinician and patient interest in enrolling for such trials is a challenge in itself, because novel drugs offer the possibility of increased disease control and therefore tend to foster the greatest interest. 56 Other challenges include limited guidelines on extrapolation of approved indications for biosimilars, the possibility of immunogenicity events in patients during testing, interchangeability with the originator drug, appropriate formulation and manufacturing of biosimilars, limited awareness of the effica cy and safety of biosimilars among health care providers, and potential political barriers. These issues are discussed in greater detail in subsequent paragraphs.
What are the end points of biosimilars?
2 For biosimilars, end points should be relevant to the disease and sensitive enough to detect clinically relevant differences between the biosimilar and its reference drug. 28 The EMA and FDA recommend using end points that can facilitate detection of differences but are not influenced by patient- or disease-related factors. 28 According to EMA guidance on end point selection, a clinical end point that measures activity (eg, ORR) as a primary end point may be considered. Assessment of ORR at a certain time point or percentage change in tumor mass from baseline is also considered appropriate. 32 OS, the preferred efficacy end point in oncology, may not be suitable to establish biosimilarity, because it can be influenced by factors that are unrelated to the differences between a biosimilar and its reference product; also, OS as an end point would require conducting much larger trials with longer follow-up periods. 32
Why is it important to validate the effectiveness of biosimilars?
Although most regulatory authorities demand clinical trials that demonstrate safety and efficacy in a structured setting , reimbursement authorities may require data in real-world settings where patient selection is not restricted by strict inclusion and exclusion criteria. 57 Real-world studies with encouraging results can also help build clinicians’ confidence in prescribing biosimilars. 58 Manufacturers realize the emerging importance of real-world data, leading to more studies of this type being conducted to complement clinical trials. 58
Is CT-P6 a biosimilar to trastuzumab?
In 2014, a trastuzumab biosimilar called CT-P6 (Celltrion; alternative name, Herzuma) was approved in Korea for the treatment of early and advanced HER2-positive metastatic breast cancers and advanced metastatic stomach cancer, the same indications as its reference biologic, Herceptin. 96 Results of a double-blind, randomized phase I/IIb study of 174 women with HER2-positive breast cancer and an Eastern Cooperative Oncology Group score of 0 or 1 showed that CT-P6 and trastuzumab had similar PK profiles. CT-P6 was well tolerated, with a safety profile comparable to that of trastuzumab. 97 In a phase III trial, which enrolled 475 patients with breast cancer at 115 sites in 18 countries, safety and efficacy (ORR, median time to progression, and median time to response) of CT-P6 plus paclitaxel compared with trastuzumab plus paclitaxel were not significantly different. In fact, there were fewer infusion and hypersensitivity reactions with the biosimilar molecule (CT-P6 plus paclitaxel, 15.6%; trastuzumab plus paclitaxel, 26%). 21
