Multiple Data Readouts on Track for the Second Half of 2022 and the First Half of 2023

Well Capitalized with Anticipated Cash Runway into 2025

EDINBURGH, United Kingdom, Aug. 17, 2022 (GLOBE NEWSWIRE) -- NuCana plc (NASDAQ: NCNA) announced financial results for the second quarter ended June 30, 2022 and provided an update on its broad clinical program with its transformative ProTide therapeutics.

As of June 30, 2022, NuCana had cash and cash equivalents of £46.5 million compared to £52.6 million as of March 31, 2022 and £60.3 million at December 31, 2021. NuCana continues to advance its various clinical programs and reported a net loss of £3.9 million for the quarter ended June 30, 2022, as compared to a net loss of £9.1 million for the quarter ended June 30, 2021. Basic and diluted loss per share was £0.07 for the quarter ended June 30, 2022, as compared to £0.17 per share for the quarter ended June 30, 2021.

“During the first half of the year, we have remained focused on the rapid and efficient implementation of our development plans,” said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. “In the past few months, we initiated two studies: NuTide:323, a randomized Phase 2 trial of NUC-3373 in combination with other agents for the treatment of second-line patients with colorectal cancer; and NuTide:303, a Phase 1b/2 study of NUC-3373 in combination with other agents including the PD-1 inhibitor pembrolizumab, for the treatment of patients with solid tumors. We also continue to enroll patients in the Phase 1b/2 NuTide:302 study of NUC-3373 in patients with colorectal cancer and the Phase 2 monotherapy part of the NuTide:701 study of NUC-7738 in patients with solid tumors, which will expand to include combination with pembrolizumab.”

Mr. Griffith continued: “From a corporate perspective, we recently announced that the Regional Court of Dusseldorf issued a judgement that Gilead’s sofosbuvir infringes our European composition-of-matter patent. We will continue to defend our patent rights and the foundational work of our late Chief Scientific Officer, Professor Chris McGuigan. Additionally, we regained compliance with the minimum bid price requirement for continued listing on the Nasdaq Global Select Market.”

Mr. Griffith concluded: “We have provided multiple data updates for both NUC-3373 and NUC-7738 that demonstrate the potential of our ProTides to offer more effective and safer treatment options for patients with cancer. These data have highlighted the compelling anti-cancer activity and favorable safety profiles and pharmacokinetic properties of our product candidates. With an anticipated cash runway into 2025 and through numerous key milestones for both NUC-3373 and NUC-7738, we remain on track to provide a number of data updates over the coming year as we continue to advance our pipeline.”

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 a PD-1 inhibitor, 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 a PD-1 inhibitor.
