NuCana Showcases Promising Results of NUC-7738 in Cancer Therapy
NuCana Unveils Significant Findings on NUC-7738 and PD-1 Inhibitors
Discovering Synergy and Enhancing Efficacy
At a recent conference, NuCana plc (NASDAQ: NCNA) shared groundbreaking data concerning their investigational cancer therapy, NUC-7738, and its combination with PD-1 inhibitors. This revelation comes from studies conducted using primary organoids sourced from renal cell carcinoma (RCC) patients, shedding light on new avenues for cancer treatment.
The scientists used patient-derived organoids (PDOs) from a select group of ten individuals battling RCC, paired with autologous tumor-infiltrating lymphocytes (TILs). By performing co-culture experiments, they found that NUC-7738 significantly boosts the effectiveness of PD-1 inhibitors, leading to a more efficient elimination of tumor cells. This innovative combination approach may emerge as a viable treatment option for patients whose cancers have stopped responding to existing therapies.
Mechanism of Action and Clinical Insights
The presentation not only highlighted the compelling results but also reiterated the mechanism through which NUC-7738 operates, as illustrated in the ongoing Phase 1/2 NuTide:701 clinical trial. Preliminary findings from this study show positive safety profiles and substantial reductions in tumor volume, along with prolonged progression-free survival for patients who are resistant to PD-1 inhibitors.
Comments from NuCana Management
Andrew Kay, Executive Chairman, expressed the enthusiasm of the company about sharing these results at the European Society for Medical Oncology Congress. He stated, "The data not only demonstrates the advantages of pairing PD-1 inhibitors with NUC-7738 but suggests a personalized approach to immune checkpoint therapy could arise from this real-time organoid model system."
Optimizing Treatment Strategies for Patients
Mr. Kay further elaborated on the importance of this research, noting that the translational data generated elevates their confidence in NUC-7738's ability to address multiple facets of the tumor microenvironment while enhancing PD-1 inhibition. He emphasized that the findings are not confined to a single cancer type, indicating that NUC-7738 may sensitize a wide array of cancers to PD-1 inhibitor therapy.
Encouraged by these substantial results, regulatory bodies have given the green light to expand the NuTide:701 study, aiming to recruit an additional 28 patients with melanoma resistant to PD-1 inhibitors. This expansion is an important next step in advancing clinical research and NuCana is actively working to enroll participants for this extended phase.

About NuCana
NuCana is a forward-thinking biopharmaceutical company dedicated to transforming cancer treatment through their innovative ProTide technology, which significantly enhances the efficacy and safety of conventional chemotherapy agents. While standard therapies continue to play a vital role in treating various cancers, they can have limited effectiveness and be poorly tolerated by patients. NuCana’s focus on improving these treatments aims not only to address the shortcomings of traditional therapies but also to deliver higher concentrations of active metabolites directly to cancer cells.
The company's pipeline features NUC-7738, designed to disrupt RNA polyadenylation processes in cancer cells and targeting the tumor microenvironment robustly. NUC-7738 is currently being evaluated in advanced stages of clinical research, testing its effectiveness both alone and in conjunction with pembrolizumab for melanoma patients. Additionally, NUC-3373, derived from 5-fluorouracil, is undergoing studies targeting various advanced solid tumors.
