NuCana Reports Third Quarter 2023 Financial Results and Provides Business Update

Announced Encouraging Updates from NUC-3373 and NUC-7738 Demonstrating Promising Efficacy and Safety Data

Pipeline Continues to Advance with Data Updates Expected for all Programs in 2024

Well Capitalized with Anticipated Cash Runway into 2025

EDINBURGH, United Kingdom, Nov. 16, 2023 (GLOBE NEWSWIRE) -- NuCana plc (NASDAQ: NCNA) announced financial results for the third quarter ended September 30, 2023 and provided an update on its broad clinical development program with its transformative ProTide therapeutics.

As of September 30, 2023, NuCana had cash and cash equivalents of £17.8 million compared to £24.6 million at June 30, 2023 and £41.9 million at December 31, 2022. NuCana continues to advance its various clinical programs and reported a net loss of £6.7 million for the quarter ended September 30, 2023, as compared to a net loss of £4.5 million for the quarter ended September 30, 2022. Basic and diluted loss per share was £0.13 for the quarter ended September 30, 2023, as compared to £0.09 per share for the comparable quarter ended September 30, 2022.

“We were excited to have recently presented promising clinical data for both NUC-3373 and NUC-7738 that continue to support the potential of our ProTides to transform the treatment of patients with cancer.” said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. “For NUC-3373, we presented the first data in second-line patients with colorectal cancer from Part 3 of the NuTide:302 study. These data supported NUC-3373’s favorable safety profile and demonstrated encouraging signs of efficacy, including tumor volume reductions in patients who have failed prior fluoropyrimidine treatment. The data also showed that most patients dosed with NUC-3373 in combination with irinotecan, leucovorin and bevacizumab (NUFIRI-bev) achieved a longer progression free survival compared to their first-line treatment with a 5-FU-based therapy. We were also pleased to report that NuTide:323, our randomized Phase 2 study of NUFIRI-bev compared to the standard of care FOLFIRI-bev in second-line patients with colorectal cancer remains on track to reach full enrollment in the coming months and that no new safety signals have been observed.”

Mr. Griffith continued: “We also presented data from the Phase 2 part of the NuTide:701 study evaluating NUC-7738 both as a monotherapy in patients with solid tumors and in combination with the anti-PD-1 therapy pembrolizumab in patients with metastatic melanoma who had exhausted standard therapies. The data showed NUC-7738 to be well tolerated with promising signs of efficacy, including tumor volume reductions and prolonged time on treatment. Importantly, these data indicated that NUC-7738 may potentiate the activity of anti-PD-1 agents in patients who were refractory to or progressed on prior immunotherapy, including anti-PD-1 therapy. We look forward to sharing additional updates as these data continue to mature.”

Mr. Griffith concluded, “We have executed on all of our goals this year and we look forward to providing numerous data updates throughout 2024, including additional data from the NuTide:323 study. With a cash runway that is expected to extend into 2025, we are excited as we continue towards our goal of improving treatment outcomes for patients with cancer.”

2024 Anticipated Milestones

• NUC-3373 (a ProTide transformation of 5-FU)
        In 2024, NuCana expects to:

  • Announce data from the Phase 2 (NuTide:302) study of NUC-3373 in combination with irinotecan, leucovorin and bevacizumab (NUFIRI-bev) and in combination with oxaliplatin, leucovorin and bevacizumab (NUFOX-bev) for the second-line treatment of patients with colorectal cancer; and

  • Announce data from the Phase 1b (NuTide:303) modular study of NUC-3373 in combination with pembrolizumab in patients with solid tumors and in combination with docetaxel in patients with lung cancer to identify additional indications for development.
    

• NUC-7738 (a ProTide transformation of 3’-deoxyadenosine)
       In 2024, NuCana expects to:

  • Announce data from the Phase 2 part of the NuTide:701 study of NUC-7738 in combination with pembrolizumab in patients with melanoma.
    

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 advanced 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 in patients with advanced solid tumors which is evaluating NUC-7738 as a monotherapy and in combination with pembrolizumab.
