NuCana Reports First Quarter 2024 Financial Results and Provides Business Update

Key Data Readouts on Track for All Programs in 2024

Randomized Phase 2 Study of 182 Second-Line Colorectal Cancer Patients Fully Enrolled

NUC-7738 plus Pembrolizumab Demonstrated Encouraging Anti-Cancer Activity in Several Patients who were Resistant to PD-1 Inhibitors

Anticipated Cash Runway into Q1 2025

EDINBURGH, United Kingdom, May 16, 2024 (GLOBE NEWSWIRE) -- NuCana plc (NASDAQ: NCNA) announced financial results for the first quarter ended March 31, 2024 and provided an update on its broad clinical development program with its transformative ProTide therapeutics.

As of March 31, 2024, NuCana had cash and cash equivalents of £12.9 million compared to £17.2 million at December 31, 2023. NuCana continues to advance its numerous clinical programs and reported a net loss of £6.8 million for the quarter ended March 31, 2024, as compared to a net loss of £7.9 million for the quarter ended March 31, 2023. Basic and diluted loss per share was £0.13 for the quarter ended March 31, 2024, as compared to £0.15 per share for the comparable quarter ended March 31, 2023.

“Our focus remains on advancing our innovative ProTide pipeline to develop more efficacious and safer medicines for patients with cancer,” said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. “NUC-3373, a transformation of 5-FU, is currently being investigated in three ongoing clinical studies. Our randomized Phase 2 study (NuTide:323) is now fully enrolled with 182 patients, and compares NUC-3373 in combination with irinotecan, leucovorin and bevacizumab (NUFIRI + bev) with the standard of care, 5-FU in combination with irinotecan, leucovorin and bevacizumab (FOLFIRI + bev) for the second-line treatment of patients with metastatic colorectal cancer. We look forward to announcing initial data from this study in 2024. We also plan to announce additional data from our ongoing Phase 1/2 study (NuTide:302) of NUFIRI + bev and NUFOX + bev in patients with metastatic colorectal cancer this year. Our Phase 1b/2 study (NuTide:303) of NUC-3373 in combination with pembrolizumab in patients with solid tumors and in combination with docetaxel in patients with lung cancer also remains on track with data readouts expected in 2024.”

Mr. Griffith continued: “Moving to NUC-7738, we recently presented exciting data at the American Association of Cancer Research (AACR) Annual Meeting. These data highlighted NUC-7738’s ability to disrupt RNA polyadenylation, leading to profound alterations in the tumor biology of the patients’ cancers. We believe that this finding provides a rationale as to why NUC-7738 plus pembrolizumab has achieved encouraging anti-cancer activity in several patients who were resistant to PD-1 inhibitors. We are evaluating NUC-7738 in an ongoing Phase 1/2 study (NuTide:701) as a monotherapy in patients with advanced solid tumors and in combination with pembrolizumab in PD-1 inhibitor-resistant patients with melanoma. We plan to announce additional data from this study in 2024.”

Mr. Griffith concluded, “We look forward to providing updates from all of our ongoing clinical studies this year as we continue working towards our mission of improving treatment outcomes for patients with cancer.”

About NuCana

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, they have significant shortcomings that limit their efficacy and they are often poorly tolerated. Utilizing our proprietary technology, we are developing new medicines, ProTides, designed to overcome the key limitations of nucleoside analogs and generate much higher concentrations of anti-cancer metabolites in cancer cells. NuCana’s 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. NUC-3373 is currently being evaluated in three ongoing clinical studies: a Phase 1b/2 study (NuTide:302) in combination with leucovorin, irinotecan or oxaliplatin, and bevacizumab in patients with metastatic colorectal cancer; a randomized Phase 2 study (NuTide:323) in combination with leucovorin, irinotecan, and bevacizumab for the second-line treatment of patients with metastatic colorectal cancer; and a Phase 1b/2 modular study (NuTide:303) of NUC-3373 in combination with the PD-1 inhibitor pembrolizumab for patients with advanced solid tumors and in combination with docetaxel for patients with lung cancer. NUC-7738 is a transformation of 3’-deoxyadenosine, a novel anti-cancer nucleoside analog. NUC-7738 is in the Phase 2 part of a Phase 1/2 study which is evaluating NUC-7738 as a monotherapy in patients with advanced solid tumors and in combination with pembrolizumab in patients with melanoma.
