NuCana Announces Upcoming Presentations on NUC-3373 at the American Association for
Cancer Research (AACR) Annual Meeting 2022
Checkpoint Inhibitor Nivolumab Activity Enhanced by NUC-3373 in vitro
NUC-3373 Shown to be a More Efficient DNA Damaging Agent in Cancer Cells than 5-FU
NUC-3373 Did Not Generate Metabolites Associated with 5-FU Dose-Limiting Toxicities
Edinburgh, United Kingdom, March 8, 2022 (GLOBE NEWSWIRE)NuCana plc (NASDAQ: NCNA) announced the release of two abstracts to be presented as posters at the American Association of Cancer Research (AACR) Annual Meeting being held from April 8 to 13, 2022.
Abstract 4992: NUC-3373 Potentiates Immune-Mediated Cytotoxicity of CRC Cells
NUC-3373 causes colorectal cancer (CRC) cell lines to release damage associated molecular patterns (DAMPs), molecular signals that can activate immune cells leading to immunogenic cell death (ICD). The addition of nivolumab, an anti-PD-1 antibody, to NUC-3373 enhanced tumor cell death in a model where cancer cells were incubated alongside human-derived immune cells, highlighting NUC-3373s potential as an attractive combination partner for checkpoint inhibitors.
Abstract 1835: NUC-3373 Targets the DNA-Directed Pathway More Effectively than 5-FU
NUC-3373 and 5-FU exert their anti-cancer effects through the metabolite, FUDR-MP (or FdUMP), which inhibits thymidylate synthase (TS), a critical enzyme for cancer cell growth and survival. Pre-clinical and clinical data show that NUC-3373 generates far higher levels of FUDR-MP than 5-FU and is more effective at inhibiting TS activity. Data indicate that NUC-3373 also induces anti-cancer activity via the DNA-targeting metabolite, FdUTP. Furthermore, NUC-3373 avoids the RNA damage associated with 5-FUs dose-limiting toxicities of diarrhea, myelosuppression and mucositis.
Through a more targeted, DNA-directed pathway, NUC-3373 may provide, if approved, a potentially more effective, safer and convenient therapeutic option than 5-FU for patients with cancer.
Hugh S. Griffith, NuCanas Founder and Chief Executive Officer said: We believe these data demonstrate NUC-3373s advantages over 5-FU and are highly supportive of our clinical development strategy. Our Phase 1/2 study of NUC-3373 in patients with colorectal cancer (NuTide:302) continues to generate data which will support our Phase 3 study for NUC-3373 in second-line colorectal cancer patients. In addition, NUC-3373 is entering a Phase 1/2 study (NuTide:303) in patients with solid tumors to identify additional indications for development, including in combination with checkpoint inhibitors.
About NuCana plc
NuCana is a clinical-stage biopharmaceutical company focused on significantly improving treatment outcomes for patients with cancer by applying our ProTide technology to transform some of the most widely prescribed chemotherapy agents, nucleoside analogs, into more effective and safer medicines. While these conventional agents remain part of the standard of care for the treatment of many solid and hematological tumors, their efficacy is limited by cancer cell resistance mechanisms and they are often poorly tolerated. Utilizing our proprietary technology, we are developing new medicines, ProTides, designed to overcome key cancer resistance mechanisms and generate much higher concentrations of anti-cancer metabolites in cancer cells. NuCanas pipeline includes NUC-3373 and NUC-7738. NUC-3373 is a new chemical entity derived from the nucleoside analog 5-fluorouracil, a widely used chemotherapy agent and is in a Phase 1b/2 study in patients with metastatic colorectal cancer. NUC-7738, is a transformation of a novel anti-cancer nucleoside analog (3-deoxyadenosine) and is in a Phase 1/2 study for patients with advanced solid tumors.
