Market Trends

Frontline Use of Enhertu in the U.s.

The use of Enhertu through advancing payloads is a key trend in the U.S. market. For example, Enhertu with pertuzumab has delivered a 40.7-month progression-free survival compared to 26.9 months for standard chemotherapy. This showcases ADCs as a potential first ­­­line treatment of care in HER2+ metastatic breast cancer across North America.

This fuels the demand for Enhertu in North America, which, in turn, contributes to the market growth.

Key Players' Consolidation Strategies

Global manufacturers are taking the ADC market towards consolidation by acquiring smaller companies to advance their clinical cancer pipelines. This highlights the importance of ADC innovation in the U.S.

• For example, in 2024, AbbVie acquired ImmunoGen to add ELAHERE to its cancer product portfolio. This acquisition proved highly beneficial for AbbVie as it generated USD 479 million in 2024, making AbbVie one of the key players in the antibody drug conjugates market.

Antibody Drug Conjugates Market Drivers

Manufacturing Scale-up Drives the Antibody Drug Conjugates Market Growth

The surge in ADC approvals has created supply challenges in the market. To overcome this, in January 2024, Samsung Biologics launched a new ADC facility, and Lonza also acquired Genentech's large-scale biologics manufacturing site in Vacaville in October 2024. These development shows that manufacturers are making production a strategic priority. Thus, manufacturers are scaling up production and securing supply chains to prepare for global demands and reduce the risk of shortage, thereby driving the market growth for ADCs.

Prescribing Adcs in Early Cancer Management Propels the Growth of the ADC Market

Global manufacturers are focusing on replacing chemotherapy with ADCs is a major factor supporting the adoption of ADCs in cancer therapy.

• For example, global manufacturers are designing trials to replace chemotherapy with ADC as a first-line therapy itself. In 2025, DESTINY-Breast09 trial proved that trastuzumab deruxtecan, when combined with pertuzumab, demonstrated higher clinical activity than chemotherapy for treating patients with HER2+ metastatic breast cancer.

Thus, by replacing chemotherapy, ADC manufacturers are developing new standards of care, where ADC is becoming a first-line treatment, which will boost the company’s revenue growth in the long run.

Market Restraints

Pricing and Rebate Competition Restrain the ADC Revenue Generation

Pricing, reimbursement, and competitive pressure reduce the revenue per unit, even when the product volume rises are a major restraint for ADC manufacturers. Gilead’s public filings and quarterly reporting for 2024 call out reimbursement pressures, rebates, and competition as explicit risks that are lowering prices of branded ADCs.

• For instance, the company’s oncology ADC Trodelvy sales increased from USD 1,063 million in 2023 to USD 1,315.0 million in 2024; however, the company finds that payer dynamics and price erosion remain key restraints for future revenue growth of ADC manufacturers.

Market Opportunities

Expanding the Application beyond Breast Cancer is A Key Opportunity for ADC Market Growth

Breast cancer is a major indication for ADC use; manufacturers are focusing on extending it into other solid tumors.

• For example, in June 2025, datopotamab deruxtecan was approved to treat non-small cell lung cancer by the FDA. Thus, for manufacturers, expanding ADC into lung cancer is a major opportunity because of the high number of patients suffering from lung cancer with high medical needs.

Thus, expanding into multiple cancers will help manufacturers to diversify revenue generation and gain a strong foothold in the market.
