Note on Biologic Patents

Matching patents to biologic drugs is far more complicated than for small-molecule drugs.

DrugPatentWatch employs three methods to identify biologic patents:

1. Brand-side disclosures in response to biosimilar applications

These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

2. General brand-side disclosures

These patents were identified from searching drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

3. Patents from broad patent text search

For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

2) High Certainty: US Patents for trastuzumab-dttb Derived from Company Disclosures

No patents found based on company disclosures

3) Low Certainty: US Patents for trastuzumab-dttb Derived from Patent Text Search

No patents found based on company disclosures

Market Dynamics and Financial Trajectory of Trastuzumab Biosimilars

Introduction to Trastuzumab Biosimilars

Trastuzumab, a biologic drug used to treat human epidermal growth factor receptor 2 (HER2) overexpressing breast cancer and metastatic gastric cancer, has seen significant market evolution with the introduction of biosimilars. This article delves into the market dynamics and financial trajectory of trastuzumab biosimilars, highlighting key trends, regional analyses, and economic impacts.

Market Growth and Projections

The global trastuzumab biosimilars market is experiencing robust growth. From $2.08 billion in 2021, the market is projected to reach $2.64 billion in 2022, with a compound annual growth rate (CAGR) of 27.1%. By 2026, the market is expected to expand to $6.90 billion, maintaining the same CAGR[1].

Regional Market Analysis

North America

North America was the largest region in the trastuzumab biosimilar market in 2021. The launch of biosimilars such as Ogivri (trastuzumab-dkst) by Biocon and Mylan in the USA has significantly contributed to this growth[1].

Middle East and Other Regions

The Middle East is anticipated to be the fastest-growing region during the forecast period. Other regions, including Asia-Pacific, Western Europe, Eastern Europe, South America, and Africa, are also showing promising growth due to increasing awareness and adoption of biosimilars[1].

Market Share and Adoption

As of Q1 2024, the biosimilar share of the trastuzumab market has reached an impressive 86%, indicating rapid adoption and acceptance of these products. This high market share is driven by the launch of multiple biosimilars, such as Kanjinti, Ogivri, Trazimera, Herzuma, and Ontruzant[4].

Average Sales Price (ASP) Trends

The introduction of biosimilars has led to significant price reductions. As of Q3 2024, the average ASP of all trastuzumab products has decreased by 63% compared to the reference product's ASP at the time of the first biosimilar launch. Biosimilars alone have seen an ASP reduction of 70%[4].

Economic Impact

Cost Savings

The entry of biosimilars has introduced substantial cost savings. For instance, a study found that at a 15% lower cost than the reference drug, 14 additional patients could be treated; at a 35% discount, an additional 47 patients could be treated[2].

Healthcare System Benefits

In the context of the Croatian healthcare system, it was estimated that biosimilars could treat more patients at a lower cost. Similar benefits are expected in other healthcare systems, making trastuzumab more accessible and affordable[2].

Financial Implications for Stakeholders

While trastuzumab is covered by Medicare Part B and Medicaid plans in the United States, the high cost of the reference product still poses significant financial burdens on practices, health systems, and patients due to out-of-pocket costs. Biosimilars are helping to alleviate these financial pressures[2].

Clinical and Therapeutic Benefits

Efficacy and Survival Rates

Trastuzumab-based regimens have been shown to improve overall survival (OS) and disease-free survival (DFS) in both early and metastatic breast cancer settings. For example, in early breast cancer, OS improved by 33% and DFS by 40%[2].

Dosage and Administration

Studies like the PERSEPHONE trial have demonstrated that 6-month adjuvant trastuzumab treatment can be noninferior to 12-month treatment, with potential cost savings and reduced side effects. This flexibility in dosage and administration routes (IV and SC) further enhances the value of trastuzumab biosimilars[2].

Competitive Landscape

Major players in the trastuzumab biosimilars market are engaged in strategic initiatives such as new product development, partnerships, and geographical expansion. Companies like Biocon, Mylan, and Samsung Bioepis are continuously launching new products and expanding their product portfolios to maintain competitive positions[1].

Regulatory and Approval Environment

The approval of multiple trastuzumab biosimilars has been a key factor in market growth. For instance, the FDA approval of Ogivri in December 2019 marked a significant milestone. The regulatory environment continues to support the entry of new biosimilars, enhancing market competition and reducing prices[1][2].

Market Dynamics and Price Erosion

Biosimilar launches have led to significant price decreases over time. On average, the ASP declined by 41% three years post the first biosimilar launch. This trend is expected to continue as more biosimilars enter the market, increasing the cost differential between reference and biosimilar drugs[3].

Future Outlook

The future of trastuzumab biosimilars looks promising, driven by increasing demand, expanding market share, and ongoing regulatory support. As more regions adopt these biosimilars, the market is expected to continue its robust growth trajectory.
