Abstract:
Antibody-drug conjugates (ADCs) are designed to manipulate the toxic efficacy of specific chemotherapeutic compounds, employing the high affinity of antibody-mediated delivery so as to drive them selectively to target cancer cells. These immunoconjugates encompass the general tendency towards precision medicine and avert the systemic toxicities of conventional chemotherapy, accomplishing an improved therapeutic index. Cumulative experience acquired from first-generation ADCs offers new perspectives to these promising therapeutic modalities for various hematological and solid cancers and propels their clinical development in a faster-than-ever pace, as indicated by the approval of four novel ADCs during the last year. This paper aims to provide an up-to-date overview of the eight ADCs approved by the US Food and Drug Administration and their current indications in oncological practice. Starting from their bio-pharmaceutical background, we track their clinical evolution, with an emphasis on the pivotal trials that led to their commercial release. Late-stage studies examining these eight ADCs in other-than-approved settings as well as the investigation of potential new candidates are also reviewed. In the close future, more data are expected to expand ADCs' oncological utility and to further reshape their role in cancer therapeutics.
Insights
Antibody-drug conjugates (ADCs) offer targeted cancer therapy with reduced side effects. This review details eight FDA-approved ADCs, their clinical evolution, and future potential in oncology.
Area of Science:
- Oncology
- Pharmacology
- Biotechnology
Background:
- Antibody-drug conjugates (ADCs) represent a precision medicine approach, combining antibody-based targeting with potent chemotherapy.
- ADCs aim to improve the therapeutic index by selectively delivering cytotoxic agents to cancer cells, minimizing systemic toxicity.
- Advancements in ADC technology and clinical experience are accelerating their development and application in various cancers.
Purpose of the Study:
- To provide an updated overview of ADCs approved by the US Food and Drug Administration (FDA).
- To examine the clinical evolution and pivotal trials of these approved ADCs.
- To review ongoing late-stage studies and emerging ADC candidates in oncology.
Main Methods:
- Review of FDA-approved ADCs and their indications.
- Analysis of clinical trial data supporting ADC approvals.
- Survey of current research on ADCs in non-approved settings and new candidates.
Main Results:
- Eight ADCs have been approved by the FDA for oncological practice.
- Significant clinical development has occurred, with four new ADCs approved recently.
- Ongoing studies are exploring expanded indications and new ADC therapies.
Conclusions:
- ADCs are a rapidly advancing therapeutic modality in oncology.
- The clinical utility of ADCs is expected to grow with further research and data.
- ADCs are poised to significantly reshape future cancer treatment strategies.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
