A review article described the totality of evidence supporting the approval of the adalimumab biosimilar AVT02 (Simlandi; Alvotech) for all approved indications of the reference product, Humira.

Despite more biosimilars entering the market and generating significant savings for payers and health care systems, these savings are not resulting in lower out-of-pocket (OOP) costs for patients, according to a recent study.

A real-world study surveying physicians and patients on adalimumab biosimilar ABP 501 (Amgevita) in inflammatory bowel disease (IBD) found both patients initiating ABP 501 and those who had switched from the reference product had higher satisfaction levels.

Two posters presented at the American Academy of Dermatology (AAD) annual meeting examined the effects of switching from reference ustekinumab and adalimumab to biosimilar versions in patients with different types of psoriasis.

Government policies, including those related to prescribing incentives and interchangeability, need to be reworked to encourage biosimilar adoption and create meaningful savings for health systems, according to speakers at a recent webinar.

A recent study used difference-in-difference analysis to assess adalimumab sales volumes and expenditures in 6 countries with and 8 countries without available biosimilar adalimumab products.

Posters from Association of Cancer Care Centers 50th Annual Meeting and Cancer Center Business Summit (AMCCBS) and the American Academy of Dermatology (AAD) highlight the benefits of incorporating biosimilars into electronic medical records and the biggest barriers for home injection of biologics.

The adalimumab biosimilar SB5 was reported to be as safe and effective as the reference product in a review of randomized controlled trials and real-world studies on immune-mediated inflammatory diseases.

Biocon Biologics settled with the maker of Eylea (aflibercept), announcing a launch date for its biosimilar competitor in Canada; Sandoz has officially acquired Cimerli, a ranibizumab biosimilar; AARP Medicare Rx from United Healthcare has added Cyltezo (adalimumab-adbm) and removed the originator (Humira) from its formulary.

A retrospective study analyzing 3 years of treatment patterns for patients with Crohn disease on biologics found that while more patients received infliximab, adalimumab, and vedolizumab initially, ustekinumab showed the highest persistence and lowest dose escalation rate, indicating potentially better clinical response compared to other biologics.

In its annual biosimilars report, Cardinal Health provided updates on how provider acceptance growth, evolving payer dynamics, and the growing pipeline for biosimilars will shape the biosimilar landscape over the next 5 years.

Samsung Bioepis provided multiple updates on its biosimilar projects, including a new partnership for its aflibercept biosimilar candidate as well as regulatory news in the European Union and Republic of Korea.

After receiving 3 complete response letters, Alvotech has officially received US approval for its adalimumab biosimilar (AVT02; Simlandi), making it the first approval for the company, the 10th biosimilar to reference Humira, and the third interchangeable adalimumab biosimilar.

At the Congress of European Crohn’s and Colitis Organisation (ECCO), Celltrion and Samsung Bioepis presented new finding from their respective biosimilar analyses, demonstrating positive safety and efficacy measures for the biosimilars as treatments for Crohn disease (CD) and ulcerative colitis (UC).

Cyltezo (adalimumab-adbm) was the first adalimumab biosimilar—and second biosimilar overall—to receive an interchangeability designation from the FDA.

Similar efficacy, safety, pharmacokinetics, and immunogenicity were found when comparing Stelara, originator ustekinumab, and CT-P43, an ustekinumab biosimilar candidate, in patients with moderate to severe plaque psoriasis.

Celltrion announced that 3 of its oncology biosimilar products have won tender contracts in France and Italy, and an experimental oral delivery device utilizing an ustekinumab biosimilar was successful in a phase 1 study.

The authors of a meta-analysis assessing several disease states found no significant differences in serious adverse events, deaths, or treatment discontinuations between patients who switched from reference products to biosimilars and those who did not.

Vizient’s most recent Pharmacy Market Outlook report showcased the success of biosimilars while also emphasizing the impact of inflation on different drug classes, particularly in oncology and immunology.

The PERFUSE study in France on biosimilar adalimumab SB5 for inflammatory bowel disease reveals high satisfaction overall, but significant variations in training and survey response rates across sites suggest a potential lack of support during treatment switches.

In addition to the several reports that have come out quantifying how the gastroenterology biosimilar market is progressing, January marks the 1-year anniversary of adalimumab biosimilar competition in the US.

The Center for Biosimilars® looks back at the first year of adalimumab biosimilars on the US market, including every product launch and approval as well as market trends and pricing strategies.
