Antibody-drug conjugates (ADCs) are transforming oncology by offering a precise, targeted approach to treatment. Combining the specificity of monoclonal antibodies with the potency of cytotoxic agents, ADCs are designed to selectively target cancer cells while reducing systemic toxicities compared to traditional therapies. As ADCs advance through clinical trials, each phase contributes essential insights into their safety, efficacy, and therapeutic potential.
The global ADC market has experienced significant growth, with a valuation of $7.35 billion in 2022. Projections indicate this market will exceed $28 billion by 2028, reflecting a compound annual growth rate (CAGR) of 25.4% during the forecast period from 2022 to 2028. This expansion is driven by the increasing prevalence of cancer, advancements in ADC technologies, and a growing pipeline of ADC candidates in clinical development.
The competitive landscape of the ADC market is marked by substantial licensing agreements and collaborations. Notably, the total licensing deal value for ADCs surged by 400% from 2017 to 2022, reaching a peak of $16.6 billion in 2022. This surge underscores the pharmaceutical industry’s commitment to investing in ADC development and commercialization. Companies are striving to differentiate themselves by exploring novel targets, innovative linker technologies, and optimized payloads to enhance the therapeutic index of ADCs. As of December 2024, there are 15 FDA-approved antibody-drug conjugates targeting 16 different cancer indications. These include both solid tumors (like breast, lung, and bladder cancers) and hematologic malignancies (like lymphomas and leukemia).
The development of ADCs involves a complex interplay of disciplines, including antibody engineering, cytotoxic drug development, and linker technology. The design of an effective ADC requires careful selection of a target antigen that is predominantly expressed on cancer cells, a potent cytotoxic agent capable of inducing cell death upon internalization, and a stable linker that ensures the conjugate remains intact in circulation but releases the drug upon reaching the target cell. Advancements in each of these components have been pivotal in overcoming previous limitations related to toxicity and efficacy, leading to the current generation of ADCs that offer improved therapeutic outcomes. ADCs offer higher probabilities of technical and regulatory success compared to other oncology drugs, making them attractive for both pharmaceutical companies and investors. The technology is seen as less risky and more modular, encouraging broader applications
Despite these advancements, challenges like immune-related side effects and payload optimization remain. However, the continued investment and focus on innovation signal a promising future for ADCs in cancer therapy.
Understanding the Antibody-Drug Conjugate Clinical Trial Landscape
To get a better idea of what ADC research looks like, we will use Citeline, a clinical trial intelligence platform, to outline what the Antibody-Drug Conjugate clinical trial landscape looks like today.
Antibody-Drug Conjugate Trials by Status
To date, there have been over 2,500 Antibody-Drug Conjugate Trials. Just over 1,300 are current. Here is a breakdown by status.

Trials by Phase
ADCs as a drug type are newer than many other approaches, so it is no surprise we are seeing a significant number of earlier phase trials, but that balance will shift as time goes on.

Antibody-Drug Conjugate Trials by Country
Looking at planned and ongoing Antibody-Drug Conjugate Trials by site location is also interesting. Here are the top 10 site locations for this phase research around the world. Rapid increase in ADC trials in China can be attributed to government support for innovative biologics, increasing domestic biopharma capabilities and a large patient pool. Also regulatory reforms in China have accelerated clinical trials approval and facilitated faster market access.
