“We are excited about the optimized development plan we recently announced for NUC-3373 in colorectal cancer and have initiated the randomized Phase 2 study, NuTide:323, in second-line patients”, said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. “We are also pleased to have initiated the NuTide:303 Phase 1b/2 study of NUC-3373 in combination with other agents, including PD-1 inhibitors, for the treatment of patients with solid tumors. In addition, we have enrolled the first patients into the Phase 2 part of the NuTide:701 study of NUC-7738. We look forward to providing numerous data updates throughout 2022 for both NUC-3373 and NUC-7738.”

Mr. Griffith continued: “Positive data that we have previously announced for NUC-3373 and NUC-7738 have demonstrated our ProTides’ potential to provide cancer patients with more efficacious and safer treatment options. These data continue to demonstrate our ProTides’ encouraging anti-cancer activity and favorable safety profiles and pharmacokinetic properties.”

Mr. Griffith concluded: “We have an anticipated cash runway which we expect will extend into 2025 and through many key milestones for both NUC-3373 and NUC-7738. We look forward to progressing towards our goal of significantly improving treatment options for patients with cancer.”

• Expand the Phase 1b/2 (NuTide:302) study of NUC-3373 in second-line colorectal cancer patients, and evaluate NUC-3373-based regimens in combination with bevacizumab;

• Announce data from the Phase 1b/2 (NuTide:302) study of NUC-3373 combined with leucovorin, irinotecan and bevacizumab in patients with colorectal cancer; and

• Announce data from the Phase 1b/2 (NuTide:303) modular study of NUC-3373 in combination with other agents in patients with solid tumors to identify additional indications for development.

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, their efficacy is limited by cancer cell resistance mechanisms and they are often poorly tolerated. Utilizing our proprietary technology, we are developing new medicines, ProTides, designed to overcome key cancer resistance mechanisms 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 and is in a Phase 1b/2 study in patients with metastatic colorectal cancer. NUC-7738, is a transformation of a novel anti-cancer nucleoside analog (3’-deoxyadenosine) and is in a Phase 1/2 study for patients with advanced solid tumors.
