Initiation of Expansion Study of NUC-7738 in Combination with Pembrolizumab for Patients with PD-1 Inhibitor-Resistant Melanoma
Initial Data from the Expansion Study of NUC-7738 Expected in Q4 2025 with Final Data in 2026
Additional Data from the Ongoing Phase 1b/2 Study of NUC-3373 in Combination with Pembrolizumab Remain on track for 2025
Anticipated Cash Runway Extended into Q4 2026 to Support Key Value-Driving Milestones and Complete the Expansion Study of NUC-7738
EDINBURGH, United Kingdom, June 02, 2025 (GLOBE NEWSWIRE) -- NuCana plc (NASDAQ: NCNA) announced financial results for the first quarter ended March 31, 2025 and provided an update on its clinical development program with its two lead anti-cancer medicines.
“We have entered 2025 with a clear focus on the advancement of our pipeline through key milestones, into late-stage development, and towards commercialization,” said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. “Our lead program, NUC-7738, continues to show significant promise. NUC-7738 is a novel agent that profoundly impacts gene expression in cancer cells and targets multiple aspects of the tumor microenvironment. In our ongoing Phase 1/2 NuTide:701 study, we have observed a favorable safety profile, meaningful tumor volume reduction and prolonged progression free-survival in patients with PD-1 inhibitor refractory and resistant metastatic melanoma. Based on these compelling results, we have recently initiated an expansion trial of NUC-7738 in an additional 28 patients with PD-1 inhibitor-resistant melanoma, that supports our registrational path. Based on this, we plan to meet with the U.S. Food and Drug Administration to determine the optimal regulatory strategy forward towards commercialization.”
Mr. Griffith continued, “Turning to our second program, NUC-3373 is a targeted thymidylate synthase inhibitor with immune modulating properties. We are encouraged by the data from the ongoing Phase 1b/2 NuTide:303 study. This study is evaluating NUC-3373 in combination with pembrolizumab in patients with advanced solid tumors, and NUC-3373 with docetaxel in patients with lung cancer. To date, we have seen notable tumor volume reductions and prolonged progression free survival in these patients. We look forward to sharing additional data from this trial later this year.”
Mr. Griffith concluded, “Lastly, we strengthened our balance sheet with a financing in May, extending our cash runway through key value-driving milestones. With multiple data readouts ahead, we are well-positioned to deliver on our mission of improving treatment outcomes for patients with cancer.”
2025 Anticipated Milestones
NUC-7738
Initiate an expansion of the Phase 1/2 study (NuTide:701) of NUC-7738 in combination with pembrolizumab in patients with PD-1 inhibitor-resistant melanoma;
Announce data from the Phase 1/2 expansion study (NuTide:701) of NUC-7738 in combination with pembrolizumab; and
Obtain regulatory guidance from the U.S. Food and Drug Administration on pivotal study design for NUC-7738 in melanoma.
NUC-3373

First Quarter 2025 Financial Highlights and Cash Position
As of March 31, 2025, NuCana had cash and cash equivalents of £4.0 million compared to £6.7 million at December 31, 2024. Subsequent to March 31, 2025, NuCana completed a financing, raising an additional £8.8 million in gross proceeds before expenses and commission. NuCana expects that its cash and cash equivalents as of March 31, 2025, together with amounts raised through its financing, will be sufficient to fund its planned operations into Q4 2026.
NuCana continues to advance its numerous clinical programs and reported a net loss of £2.5 million for the quarter ended March 31, 2025, as compared to a net loss of £6.8 million for the quarter ended March 31, 2024. Basic and diluted loss per ordinary share was £0.02 for the quarter ended March 31, 2025, as compared to £0.13 per ordinary share for the comparable quarter ended March 31, 2024.
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-7738 and NUC-3373. NUC-7738 is a novel anti-cancer agent that disrupts RNA polyadenylation, profoundly impacts gene expression in cancer cells and targets multiple aspects of the tumor microenvironment. 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. 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 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.
