Coherus BioSciences Reports Promising Clinical Data for Novel Liver Cancer Treatment
Coherus BioSciences, Inc. a biotechnology firm, has recently shared optimistic findings from a Phase 2 clinical trial of a new therapeutic candidate, casdozokitugatezolizumabbevacizumab (casdozo), for the treatment of liver cancer. The results were presented at the 2024 ASCO Gastrointestinal Cancers Symposium, marking a significant milestone in the company’s pursuit of innovative cancer treatments.
The clinical trial concentrated on patients with unresectable locally advanced or metastatic hepatocellular carcinoma (uHCC), a particularly aggressive form of liver cancer. The data revealed an objective response rate of 38%, which included three instances of complete response, indicating the potential efficacy of the treatment.
Casdozo, a selective antibody that targets IL-27, has been identified as a promising new approach in cancer therapy. IL-27, an immunoregulatory cytokine, plays a crucial role in the immune system’s response to cancer. The uniqueness lies in its status as the sole clinical stage immunomodulatory cytokine antagonist that specifically targets IL-27. This specificity could offer a new avenue for combination therapy in treating advanced solid tumors.
The initial portion of the trial evaluated the safety and tolerability of combining casdozo with atezolizumab and bevacizumab, which are standard-of-care therapies. The assessment involved 30 treatment-naïve patients with uHCC. The primary focus was on safety, while secondary endpoints included progression-free survival (PFS) and overall response rate (ORR) based on the review by investigators. The findings up to November 9, 2023, suggest that the combined blockade of IL-27, PD-(L)1, and VEGF pathways by casdozoatezobev is well-tolerated.
Dr. Daneng Li, an Associate Professor at the City of Hope Comprehensive Cancer Center, underscored the urgency for new treatment modalities that can enhance survival rates for liver cancer patients without increasing toxicity. He also noted the potential to allow for the identification of biomarkers that predict response to treatment, which could be particularly beneficial given the individual variability of tumors and related factors.
Coherus BioSciences’ extensive clinical development program is actively pursuing additional trials in combination with toripalimab-tpzi, an anti-PD-1 antibody. The objective is to extend patient survival and enhance outcomes by counteracting immune suppression within the tumor microenvironment.
The early clinical data in the treatment of uHCC are indeed promising, demonstrating a balance of efficacy and safety. The potential for casdozo to redefine the standard of care for liver cancer patients is bolstered by its novel mechanism of action and the positive outcomes of the Phase 2 clinical trial. As Coherus BioSciences proceeds with further clinical development, the company remains dedicated to improving treatment options for patients contending with this formidable disease. This commitment is reflected in their continuous research and development endeavors aimed at delivering innovative therapies that could substantially improve patient care.
The preliminary clinical results for casdozo present a hopeful outlook for the future of liver cancer treatment. With its unique mechanism and encouraging trial outcomes, the therapy stands as a testament to the company’s dedication to advancing medical care for those afflicted by this challenging condition. The ongoing research and development are set to continue shaping the landscape of liver cancer therapy, with a steadfast focus on patient benefit and outcome enhancement.
