CD70 Targeted Therapies In Cancer

Release Date: 25-Jan-2024

The attention of stakeholders in the dynamic landscape of cancer therapy is rapidly turning to CD70-targeted treatments as a possible avenue for innovative intervention. CD70, a protein seen in many malignancies, has piqued the interest of both researchers and pharmaceutical companies. Looking beyond the complicated nature of their functioning, the full significance of CD70-targeted therapies is shown in what they represent for both cancer patients and the pharmaceutical industry. The investigation of CD70 as a therapeutic target holds the prospect of more effective and customized therapy choices for cancer patients. Simultaneously, in the pharmaceutical sector, CD70-targeted treatments represent a possible breakthrough area, spawning a rush of research and development aimed at changing the course of cancer care.

CD70 is a surface molecule frequently overexpressed in various cancers and but shows restricted expression in non-malignant cells, that too only on cells of the hematopoietic system, therefore presents advantages over traditional cancer therapies. Unlike broad-spectrum treatments with indiscriminate effects on healthy cells, targeting CD70 allows for a more focused approach. this selectivity is crucial in reducing collateral damage and potential side effects, making CD70-targeting therapies a more patient-friendly option. Furthermore, CD70’s role in promoting cancer cell survival and immune evasion positions it as a strategic target for interventions that not only directly attack cancer cells but also disrupt the support mechanisms that sustain their growth.


The potential implications of CD70-targeted therapies for cancer patients are diverse and extend beyond a singular dimension. Through the precise targeted of cancer cells characterized by the overexpression of CD70, these therapeutic interventions carry the promise of not only bolstering treatment outcomes but also mitigate adverse effects. This specific targeting approach not only amplifies the efficacy of current treatment but also opens up novel possibilities for synergistic combination therapies. For patients navigating the challenging landscape of cancer treatment, this translates into an envisaged improvement in the overall treatment experience.


The study of CD70 as a therapeutic target has progressed beyond theoretical speculation and is now into the realm of current clinical research. A number of clinical trials are underway, examining the efficacy and safety characteristics of various CD70-targeted treatments. These trials span a wide range of cancer types, including both solid and hematological cancers, emphasizing on the remarkable versatility of CD70 as a viable target across various malignancies. A majority of these clinical trials are currently in early phase, demonstrating the recent boom in clinical development and evolution of CD70-targeting therapies. The knowledge gained from these ongoing trials will be crucial in shaping the trajectory of CD70-targeted treatments.


One notable advancement in CD70-targeted therapy is the development of monoclonal antibodies like Seagen’s SEA-CD70. Engineered to block the interaction between CD70 and its receptor CD27, SEA-CD70 functions by inducing antibody-dependent cellular cytotoxicity (ADCC). This innovative approach, developed on Seagen’s sugar engineered antibody (SEA) technology, underscores the potential of precise and targeted interventions. This specific mechanism of action highlights the sophistication of current research in tailoring therapeutic strategies to the intricacies of cancer biology.


In the dynamic landscape pf pharmaceutical advancements, licensing agreements play a pivotal role in propelling promising candidates toward clinical application. An example is the collaboration between argenx and OncoVerity, culminating in a licensing agreement for argenx’s Cusatuzumab in March 2023. argenx granted OncoVerity global licensing rights to the CD70-targeting monoclonal antibody Cusatuzumab and a fund of US$ 30 Million under this agreement. This strategic partnership signifies a shared commitment to advancing CD70-targeting therapies, pooling resources and expertise to navigate the intricate journey from research to clinical application.


Within the realm of cancer therapeutics, CAR-T (Chimeric antigen receptor T-cell) therapies have assumed a dominant position, with CD70 emerging as another prime target in several clinical trials. Some CD70 CAR-T cell therapies undergoing clinical trials at present have been developed by UTC Therapeutics, CRISPR Therapeutics, Chongqing Precision Biotech, Shenzhen Geno-Immune Medical Institute and the University of Florida. The involvement of pharmaceutical companies, cancer centers, hospitals and universities in advancing these CD70 CAR-T cell therapies exemplifies the collaborative efforts being put in propelling these candidates forward.


Looking ahead, the CD70 approach holds immense promise for altering the landscape of cancer treatment. Ongoing clinical trials, development of novel clinical trials and prominence of CAR-T therapies, and license agreements all present a picture of a rapidly evolving sector. The personalized nature off CD70-targeted therapies, with their potential advantages and fewer side effects, suggests that cancer care will become more individualized and successful in the future. In the progression of medical science, CD70 is a beacon of hope, delivering a targeted strategy in the relentless pursuit of better outcomes for cancer patients.
