The rising number of cases of breast cancer and clinical trials related to Trastuzumab further support regional market growth.
Europe is considered to be a significantly growing area. The growth of the Herceptin market in Europe can be driven by ongoing research into cancer. The availability of reimbursement policies for cancer drugs influences the market. In addition, the increasing burden of breast cancer and the region’s well-established healthcare sector contributes to the growth of the market in the region.
Herceptin is a targeted therapy that treats primarily HER2-positive breast cancer. Its generic name is Trastuzumab. Herceptin functions as a monoclonal antibody that selectively attaches to the human epidermal growth factor receptor 2 (HER2) protein that various cancers exhibit through excessive expression. The U.S. Food and Drug Administration approved Herceptin as a treatment for metastatic breast cancer in 1998. Herceptin receives attention for medical use for breast cancer at various stages of progression while treating some cases of HER2-positive gastric cancers.
The Herceptin market is witnessing rapid growth due to rising healthcare investments and the introduction of subcutaneous versions for enhanced convenience. The rapid expansion of the healthcare infrastructure and increasing investments in novel drug discovery and development further contribute to market expansion. Trastuzumab, an active ingredient in Herceptin, gains status as a vital treatment component for global oncology strategies because of improved diagnostic methods and growing public and private healthcare funding.

Growing Demand for Personalized Medicine
The rising demand for personalized medicine is a major factor that drives the growth of the Herceptin market. Medical practitioners can use genetic and companion diagnostics to provide care to HER2-positive tumor patients with fewer adverse effects. The specified treatment approach delivers superior results for patients with better healthcare resource efficiency. With the increasing prevalence of HER2-positive breast and genetic cancers, the need for personalized medicine is rising. Personalized medicine emerged as the fundamental treatment in oncology practice, strengthening its position in the precision medicine approach.
Patent Expiry and Growing Biosimilar Competition
One of the significant challenges in the Herceptin market is the expiry of the drug. The additional supply of biosimilars puts enormous pressure on pharmaceutical companies to discontinue their efforts in product innovation, the adoption of new drug delivery technology, and the development of combinational treatment approaches. The loss of brand loyalty and decreased exclusive status becomes a major challenge for companies to recover their original research and development investments. Biosimilar competition and patent expiry are major factors that reduce research and development progress within the market. Moreover, the availability of other HER2-targeted therapies restrains the market's growth.
Shift Toward Combination and Sequential Therapies
The Herceptin market continues to surge in the coming years due to rising doctors' recommendations for combination therapy and sequential treatments. This refers to the infusion of Trastuzumab with chemotherapy drugs, biologics, and antibody-drug conjugates (ADCs) that clinicians are using as the primary goal to improve the therapeutic outcomes of HER2-positive cancer patients. Patients with advanced conditions show better clinical outcomes using these combination treatments. These treatments make Herceptin effective throughout different therapeutic stages to enhance disease control. The increased use of combination treatments and sequence regimens expands the scope of applications of Herceptin, making it a vital component of advanced HER2-positive cancer therapy options.
The biosimilar segment led the Herceptin market with the largest share in 2024. This is mainly due to the increased acceptance of biosimilars in the treatment of HER2-positive cancer. Biosimilar adoption rates keep increasing because of the expiration of Herceptin patents. As healthcare providers seek affordable oncology treatments, the demand for biosimilars increases. Biosimilars are inexpensive, making them accessible to patients. The biologic segment is anticipated to witness notable growth in the market over the projection period. The growth of the segment is attributed to the increasing demand for personalized medicine. Biologics are suitable for personalized medicine, allowing for tailored treatments based on individual profiles. HER2-positive cancer can be effectively treated using biological drugs, serving as primary treatments.
The breast cancer segment held the largest share of the Herceptin market in 2024 and is expected to grow at a steady rate throughout the forecast period. This is mainly due to the rising prevalence of HER2-positive breast cancer worldwide, prompting the demand for Trastuzumab. Improved diagnostic methods and lifestyles and genetic changes have increased the number of breast cancer diagnoses, creating a greater need for effective treatments. Herceptin become more significant because of its proven efficacy in treating breast cancer. It is also used as a targeted HER2 treatment.
The stomach/gastric cancer segment is anticipated to grow at the fastest rate in the coming years. High numbers of diagnosed HER2-positive gastric and gastroesophageal junction (GEJ) cancers encourage the use of Herceptin. Therapeutic use of Herceptin expanded beyond first-line therapy after regulatory bodies approved its use in major markets such as North America, Europe, and Asia Pacific, enabling more patients to access this targeted therapy. Expanding research to explore the therapeutic effects of Trastuzumab in immunotherapy and chemotherapy is likely to continue to increase its role in evolving gastric cancer treatments.
The commercial/private segment dominated the Herceptin market with the largest share in 2024. This is mainly due to the increased commercial insurance coverage for trastuzumab originator versions and their biosimilar counterparts, which sustains patient treatment access. The increased prevalence of breast cancer and the high costs associated with treatments encourage commercial insurance providers to offer more insurance coverage that covers treatments. HER2-targeted therapy demand and increasing cancer rates reinforce the segment’s position in the market.
The public segment is expected to expand at the fastest rate over the studied period. The rising healthcare programs and oncology funding by governments serve as the driving force behind the segmental growth. Public insurers such as Medicare and Medicaid are providing coverage for biosimilar trastuzumab because these alternatives help manage HER2-positive cancer. The expansion of public trastuzumab treatment significantly reduces healthcare costs.
The hospital pharmacies segment contributed the largest market share in 2024. This is mainly due to the increased volume of patient with HER2-positive cancer. Herceptin and its biosimilar versions are typically administered intravenously, requiring professional supervision for proper monitoring. Hospital pharmacies often have skilled pharmacists, which help patients with administering Herceptin. The availability of insurance coverage and reimbursement policies for hospital treatments further bolstered the segment’s growth. Hospital pharmacies maintain their position as the main distribution channel due to the increased government support.
The specialty pharmacy segment is expected to grow substantially in the Herceptin market. Specialty pharmacies specializing in handling complex medications, including Herceptin. The rising demand for subcutaneous formulations and outpatient cancer treatments drives the growth of the segment. Specialty pharmacies deliver personalized services and counselling services, attracting more patients. These pharmacies collaborate with payers to secure payments and deliver the most suitable therapy to patients. Specialty pharmacies act as essential distribution channels by optimizing drug utilization while providing superior patient care services for trastuzumab treatments.
