The U.S. biosimilars market size was valued at USD 6.73 billion in 2021 and is projected to grow from USD 9.48 billion in 2022 to USD 100.75 billion by 2029, exhibiting a CAGR of 40.2% during the forecast period. Based on our analysis, the market exhibited a higher growth of 105.4% in 2020 as compared to 2019. The global COVID-19 pandemic has been unprecedented and staggering, with experiencing higher-than-anticipated demand across all regions compared to pre-pandemic levels. 

Biosimilars became a new classification of Food and Drug Administration (FDA)-approved drugs according to the “Biologics Price Competition and Innovation Act” in 2010. They have the potential to allow for patient access to more cost-effective alternatives and may foster a competitive environment for the future development of biologic medicines. As the key biologics have begun to come off-patent in the U.S., there has been growing interest in biosimilars development that can compete with the potency and efficacy of existing biologics. Despite reflecting a slow start, the U.S. is expected to emerge as one of the fastest-growing markets in the coming years.

As of April 2022, the number of approved biosimilars by the U.S. FDA in the U.S. is 35, out of which 21 have been made commercially available in the U.S. market. They offer comparable clinical utility over their reference products at a lower cost, which is a key factor for their rising uptake in the U.S. market.


The Market Witnessed a Minimal Impact amid COVID-19 Pandemic

The outbreak of COVID-19 had minimal impact on the sales generated by these drugs in the U.S. The prevailing trend is attributable to improved supply chain management and enhanced R&D capabilities.

  • For instance, in 2021, the global biosimilars business of Pfizer reported a revenue of USD 2.34 billion. The U.S. contributed to almost 66.6% of the revenue by generating USD 1.56 billion.

However, due to the outbreak of COVID-19, the financial year 2021 witnessed only 4 FDA approval and two biosimilars were launched in the U.S., as compared to 10 approvals and 6 launches in 2019. The trend was mainly attributed to the cof regulatory approvals during the pandemic and increased focus on approvals and the development of vaccines and treatment related to COVID-19 therapy.

Despite the lower approvals in 2021, the FDA reported numerous biosimilars-related submissions in the pipeline at FDA for the fiscal year 2021. This is projected to compensate for the slower growth rate of the market in the U.S. in 2021 and limit the impact of COVID-19 on the overall revenues generated from them during the period.

Patent Expiry of Blockbuster Biologics to Increase the Uptake of these Drugs

According to McKinsey report, a number of blockbuster biologics with annual peak sales worth USD 60 billion will lose patent protection in the coming years. Since the top 25 biologics drive approximately 83% of the global sales, the patent expiry of many of these products has opened new possibilities for the market players. Taking complete advantage of the loss of patents for these biologics, the wave of biosimilars has entered the U.S. market with the introduction of highly effective and potent drugs.

  • For instance, in April 2020, Samsung Bioepis and Merck collaborated and launched the trastuzumab biosimilar Ontruzant in the U.S. market.

Also, the treatment with biologics therapy is much more expensive, owing to higher Average Sales Price (ASP) of biologics. Therefore, taking into consideration the growing prevalence of chronic diseases, such as cancer and rheumatoid arthritis, the adoption of these drugs is anticipated to be pronounced in the U.S. market.

  • For instance, according to a 2021 article by Dotdash Publishing, Amgen drug Neulasta to treat neutropenia costs more than USD 10,000 per ml, whereas its biosimilar, Ziextenzo, costs around USD 6,500 per ml, which saves around 37% overall cost.


Growing Strategic Partnerships and Commercial Agreements in the U.S. to Augment the U.S. Biosimilars Market Growth

Biosimilars' clinical and economic benefits are showing great promise in the U.S. healthcare industry. According to the RAND Corporation, the robust uptake of these drugs across the globe can reduce direct spending on biologics by USD 54 billion by the end of 2026. To gain a competitive advantage in such a growing industry in the U.S., various drug-makers are entering into strategic partnerships, collaborations, and acquisitions for their development, manufacturing, or commercialization. The collaborations aim to make high-quality, affordable drugs accessible to patients in various therapeutic areas.

  • For instance, in February 2022, Biocon Biologics entered into a definitive agreement to acquire the biosimilars business of Viatris, a global franchise focused on oncology, immunology, and endocrinology, with an aim to strengthen its position through its portfolio and future pipeline biosimilar drugs.

The market in the U.S. is considered to be fairly flat and is emerging at a slower pace with a regulatory framework being set in place. The partnerships are thus enabling the competing companies to strengthen their ability to deliver the next-generation drugs and improve the accessibility of these drugs in the U.S. Considering the ongoing litigations, the innovators are entering into agreements with biologic manufacturers. This is a factor attributed to driving the market during the forecast period.

  • In April 2018, AbbVie Inc., entered into an agreement with Samsung and Amgen for Humira biosimilars in which AbbVie will begin granting country-by-country licenses to both the companies in Europe, with the U.S. expecting the arrival by mid-2023.


Challenges with Drug Development, Clinical Processing, and Cost of Development to Hinder the Market Growth

Usually, generic drugs are 40% to 50% less expensive than branded pharmaceuticals and biologics. In contrast, biosimilars are just 15% to 20% cheaper than biologics. This is attributed to high development costs, clinical testing, and high resource investment. Additionally, generic drugs require fewer modifications, making the manufacturing process easy and less costly. The development costs for generic drugs range from around USD 2-3 million, whereas the development cost of biosimilars is higher.

  •  For instance, according to a 2021 article published by Springer Link, the cost of developing and gaining approval for a biosimilar in the U.S. ranges between USD 100.0 million to USD 200.0 million, which is significantly higher than the cost of developing generic drugs, which ranges between USD 1.0 million to USD 5.0 million.

Along with this, biosimilar development takes around five to nine years compared to the development of generic drugs, which takes approximately two years. So this time duration is considered very long from the investor's and manufacturers’ point of view. This restraining factor is anticipated to slow down the market growth during the forecast period.

Hence, the factors mentioned above, coupled with limited information on efficiency due to which the healthcare providers are reluctant to switch to biosimilars, are limiting the growth of these drugs in the U.S. market.
