On Track to Present Data Updates from All Ongoing Clinical Studies in the Second Half of 2023

Well Capitalized with Anticipated Cash Runway into 2025

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

As of June 30, 2023, NuCana had cash and cash equivalents of £24.6 million compared to £31.0 million at March 31, 2023 and £41.9 million at December 31, 2022. NuCana continues to advance its various clinical programs and reported a net loss of £5.4 million for the quarter ended June 30, 2023, as compared to a net loss of £3.9 million for the quarter ended June 30, 2022. Basic and diluted loss per share was £0.10 for the quarter ended June 30, 2023, as compared to £0.07 per share for the comparable quarter ended June 30, 2022.

“During the first half of 2023, we focused on advancing our ProTides through clinical development and look forward to providing data updates from these studies in the second half of this year,” said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. “We anticipate data updates from the three ongoing studies of NUC-3373, a ProTide that has the potential to replace 5-FU across multiple tumor types. These studies include: the Phase 2 part of the NuTide:302 study evaluating NUC-3373 combined with leucovorin and either irinotecan (NUFIRI) or oxaliplatin (NUFOX) plus bevacizumab in second-line patients with colorectal cancer; the randomized Phase 2 NuTide:323 study of NUFIRI plus bevacizumab compared to the standard of care FOLFIRI plus bevacizumab in patients with second-line colorectal cancer; and the Phase 1b/2 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.”

Mr. Griffith continued: “NUC-7738, our ProTide transformation of 3’-deoxyadenosine continues to progress well. We anticipate sharing data later this year from the Phase 2 part of the NuTide:701 study investigating NUC-7738 as monotherapy in patients with solid tumors and in combination with pembrolizumab in patients with melanoma.”

Mr. Griffith concluded, “With a cash runway expected to extend into 2025 and through many key milestones for both NUC-3373 and NUC-7738, we look forward to a busy and exciting rest of the year as we progress towards our goal of significantly improving treatment outcomes for patients with cancer.”

2023 Anticipated Milestones

      In 2023, NuCana expects to:
  
  
  • Announce data from the Phase 2 (NuTide:302) study of NUC-3373 combined with irinotecan and bevacizumab (NUFIRI-bevacizumab) and in combination with oxaliplatin and bevacizumab (NUFOX-bevacizumab) in second-line patients with colorectal cancer;
  • Announce preliminary data from the randomized Phase 2 (NuTide:323) study of NUFIRI-bevacizumab versus the standard of care FOLFIRI-bevacizumab 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 2023, NuCana expects to:
  
  
  • Announce data from the Phase 1 part of the NuTide:701 study of NUC-7738 in patients with solid tumors; and
  • Announce data from the Phase 2 part of the NuTide:701 study of NUC-7738 as monotherapy in patients with solid tumors and 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.
