NuCana Reports Fourth Quarter and Year-End 2022 Financial Results and

Provides Business Update

Multiple Important Data Readouts Expected in 2023

Well Capitalized with Anticipated Cash Runway into 2025

Edinburgh, United Kingdom, April 4, 2023 (GLOBE NEWSWIRE) – NuCana plc (NASDAQ: NCNA) announced financial results for the fourth quarter and year ended December 31, 2022 and provided an update on its broad clinical program with its transformative ProTide therapeutics.

As of December 31, 2022, NuCana had cash and cash equivalents of £41.9 million compared to £50.8 million as of September 30, 2022 and £60.3 million at December 31, 2021. NuCana continues to advance its various clinical programs and reported a net loss of £15.2 million for the quarter ended December 31, 2022, as compared to a net loss of £13.6 million for the quarter ended December 31, 2021. Net loss for the year ended December 31, 2022 was £32.0 million, compared to a net loss of £40.5 million for the year ended December 31, 2021. Basic and diluted loss per share was £0.29 for the quarter and £0.61 for the year ended December 31, 2022, as compared to £0.26 per share for the comparable quarter and £0.78 for the year ended December 31, 2021.

“We had a very productive 2022 as we achieved numerous development milestones for NUC-3373 and NUC-7738,” said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. “During the year, we determined the recommended Phase 2 dose for both NUC-3373 and NUC-7738. Both of these product candidates have progressed to Phase 2 development and are being evaluated in novel combinations and additional indications. We also presented promising efficacy and safety data that continue to demonstrate the potential of our ProTides to offer more effective and safer treatment options for patients with cancer.”

Mr. Griffith continued: “Looking ahead to 2023, we expect to make several important data announcements across our pipeline. For NUC-3373, which we believe has the potential to replace 5-FU across multiple tumor types, we plan to provide updates from three clinical studies: the Phase 2 part of NuTide:302 in which NUC-3373 is being combined with leucovorin and either irinotecan (NUFIRI) or oxaliplatin (NUFOX) plus bevacizumab in patients with second-line colorectal cancer; NuTide:323, a randomized Phase 2 study of NUFIRI plus bevacizumab compared to the standard of care FOLFIRI plus bevacizumab for the second-line treatment of patients with colorectal cancer; and NuTide:303, a Phase 1b/2 modular study of NUC-3373 in combination with pembrolizumab in patients with various solid tumors and in combination with docetaxel in patients with lung cancer.”

Mr. Griffith added: “NuTide:323 will include 171 patients and compare NUFIRI plus bevacizumab based on weekly and alternate weekly NUC-3373 dosing schedules to FOLFIRI plus bevacizumab. We believe NuTide:323 has the potential to provide meaningful data in our target population of second-line patients with colorectal cancer and enable us to optimize a Phase 3 study. Additionally, given 5-FU’s broad usage across multiple tumor types, we are excited to be expediting the NuTide:303 study, which is designed to identify novel combinations and additional indications for development.”

Mr. Griffith said: “For NUC-7738, which is based on a novel nucleoside, 3’-deoxyadenosine, we look forward to announcing data from the Phase 2 part of the NuTide:701 study which is investigating NUC-7738 both as a monotherapy in patients with solid tumors and in combination with pembrolizumab in patients with melanoma.”

Mr. Griffith concluded: “Overall, we are pleased with the progress we have made with NUC-3373 and NUC-7738 in 2022. With a cash runway expected to fund operations into 2025, we look forward to an exciting year for NuCana.”

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, in combination with other agents, is in a Phase 1b/2 study in patients with metastatic colorectal cancer. NuCana has also initiated a randomized Phase 2 study of NUC-3373, in combination with other agents, for the second-line treatment of patients with advanced colorectal cancer. In addition, NuCana has initiated a Phase 1b/2 modular study of NUC-3373 in combination with other agents, including

the PD-1 inhibitor pembrolizumab, in patients with advanced solid tumors to identify additional indications for development. 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 in patients with advanced solid tumors which is evaluating NUC-7738 as a monotherapy and in combination with pembrolizumab.
