NuCana Reports Third Quarter 2019 Financial Results and Provides Business Update

Opens Phase III Global Biliary Tract Cancer Study (NuTide:121) with Potential for Accelerated Approval Filing

Focusing Resources on Key Value-Driving Programs of Biliary Tract Cancer and Colorectal Cancer

Cash and Cash Equivalents to Fund Operations into the Second Half of 2021

Numerous Clinical Data Announcements and Study Initiations Expected in 2020

EDINBURGH, United Kingdom, Nov. 13, 2019 (GLOBE NEWSWIRE) -- NuCana plc (NASDAQ: NCNA) announced financial results for the third quarter ended September 30, 2019 and provided an update on its extensive clinical program with its transformative ProTide™ therapeutics.

As of September 30, 2019, NuCana had cash and cash equivalents of £58.1 million compared to £65.2 million as of June 30, 2019 and £77.0 million as of December 31, 2018. NuCana continues to advance its various clinical programs and reported a net loss of £3.9 million for the quarter ended September 30, 2019, as compared to £2.5 million for the quarter ended September 30, 2018. Basic and diluted loss per share was £0.12 for the quarter ended September 30, 2019, as compared to £0.08 per share for the quarter ended September 30, 2018.

"We are making excellent progress advancing our pipeline of novel ProTides,” said Hugh S. Griffith, NuCana’s Founder and Chief Executive Officer. "We recently announced that we have received FDA clearance of our IND and have commenced patient enrollment in NuTide:121, our global Phase III study comparing Acelarin plus cisplatin to gemcitabine plus cisplatin in patients with advanced biliary tract cancer.  We are excited that NuTide:121 has the potential to support both accelerated as well as full approval filings and we look forward to expediting the recruitment of patients to this study.”  NuTide:121 will enroll up to 828 patients in approximately 120 sites across North America, Europe, Asia and Australia.  The primary objectives are Overall Survival (OS) and Objective Response Rate (ORR). Three interim analyses, including two designed to support accelerated approval, are planned as part of the Phase III study protocol in addition to the final analysis.

Mr. Griffith continued: "We are also excited about the potential of our other two ProTides in the clinic.  We recently presented initial PK data from part one of NuTide:302, the Phase Ib study of NUC-3373 in combination with other agents typically combined with 5-FU in patients with advanced colorectal cancer.  We believe NUC-3373 has significant commercial potential as more than 500,000 patients in North America are estimated to receive 5-FU each year.  We also announced non-clinical data on NUC-7738, our ProTide transformation of a novel nucleoside analog, 3’-deoxyadenosine, detailing multiple potential anti-cancer modes of action.”

NuCana also announced that it is prioritizing resources on its two key programs: Acelarin in biliary tract cancer and NUC-3373 in colorectal cancer. Mr. Griffith remarked: "While our ProTides have the potential to become the new standard of care across multiple indications, we need to focus on programs that we believe will deliver the greatest clinical benefit to patients and create the most value for shareholders. In prior studies, Acelarin has generated positive data in patients with ovarian cancer, both as a single agent as well as in combination with carboplatin. We plan to announce data from the ongoing PRO-105 study of single-agent Acelarin in patients with platinum-resistant ovarian cancer in the first half of 2020. However, the advent of PARP inhibitors has changed the treatment landscape for patients with ovarian cancer resulting in a more complex regulatory pathway for single-agent therapy. We have been highly encouraged by the synergy we have observed with Acelarin in combination with platinum agents, both in patients with biliary tract cancer and ovarian cancer. Thus, should we elect to pursue further development of Acelarin in patients with ovarian cancer, we would anticipate combining it with a platinum agent.”

Based on this prioritization of resources, NuCana believes its current cash and cash equivalents will be sufficient to fund its planned operations into the second half of 2021 as compared to its previous expectation of into 2021. In addition to continuing or completing the ongoing clinical studies, NuCana expects its current cash and cash equivalents will enable the following:   

  •  Continuing to run the Phase III study of Acelarin in combination with cisplatin in patients with biliary tract cancer;
  •  Initiating a Phase II/III study of NUC-3373 in combination with other agents for patients with colorectal cancer.

Mr. Griffith concluded: "We look forward to announcing more data throughout 2020.  We have continued to validate our ProTide technology’s ability to transform some of the most widely prescribed chemotherapy agents into what we believe will be more efficacious and safer treatments. With multiple milestones expected across our pipeline, we anticipate a busy and productive 2020 for NuCana.”

Anticipated Milestones

  •  Acelarin is NuCana’s ProTide transformation of gemcitabine. In 2020, NuCana expects to:

• Provide an update on enrollment in the Phase III study of Acelarin combined with cisplatin as a first-line treatment for patients with advanced biliary tract cancer.
• Report data from the ongoing Phase II study (PRO-105) of single-agent Acelarin for patients with platinum-resistant ovarian cancer.
• Provide an update on the investigator-sponsored Phase III study (Acelarate) of Acelarin as a first-line treatment compared to gemcitabine for patients with metastatic pancreatic cancer, for which enrollment has been suspended.

  •  NUC-3373 is NuCana’s second ProTide in clinical development, a transformation of the active anti-cancer metabolite of 5-FU. In 2020, NuCana expects to:

• Report data from the ongoing Phase Ib study (NuTide:302) of NUC-3373 in patients with advanced colorectal cancer and establish the recommended Phase II dose of NUC-3373 in combination with other agents with which 5-FU is typically combined, including leucovorin, oxaliplatin and irinotecan.
• Contingent on regulatory guidance and other factors, initiate a Phase II/III study of NUC-3373 in combination with other agents for patients with colorectal cancer.
• Report data from the ongoing Phase I study (NuTide:301) of NUC-3373 in patients with advanced solid tumors.
  

  •  NUC-7738 is NuCana’s ProTide transformation of a novel nucleoside analog, 3’-deoxyadenosine. In 2020, NuCana expects to: 

• Report data from the Phase I study (NuTide:701) of NUC-7738 in patients with advanced solid tumors.

About Biliary Tract Cancer

Biliary tract cancer, including cholangiocarcinoma, gallbladder and ampullary carcinoma, is cancer originating in the bile duct, a vessel that transports bile from the liver to the gall bladder and small intestine. Approximately 178,000 new cases of biliary tract cancer are diagnosed each year worldwide, with more than 18,000 of those diagnoses in the United States.  There are currently no agents approved for the treatment of biliary tract cancer; however, the worldwide standard of care in biliary tract cancer patients with locally advanced or metastatic disease is the combination of gemcitabine and cisplatin. Patients receiving this regimen have a median overall survival of 11.7 months.

About Colorectal Cancer

Colorectal cancer is a cancer that starts in the colon or the rectum.  In the United States, approximately 145,000 new cases of colorectal cancer and 51,000 deaths due to the disease are expected in 2019. Worldwide, there were over 1.8 million new colorectal cancer cases in 2018, and the global burden is expected to increase to more than 2.2 million new cases and 1.1 million deaths annually by 2030. Most systemic therapies for colorectal cancer include 5-FU, typically in combination with other therapeutic agents such as oxaliplatin or irinotecan. 5-FU remains the single most prescribed compound for the treatment of colorectal cancer.

About NuCana plc

NuCana is a clinical-stage biopharmaceutical company focused on significantly improving treatment outcomes for cancer patients 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. Our most advanced ProTide candidates, Acelarin and NUC-3373, are new chemical entities derived from the nucleoside analogs gemcitabine and 5-fluorouracil, respectively, two widely used chemotherapy agents. Acelarin is currently being evaluated in four clinical studies, including a Phase III study for patients with biliary tract cancer, a Phase Ib study for patients with biliary tract cancer, a Phase II study for patients with platinum-resistant ovarian cancer and a Phase III study for patients with metastatic pancreatic cancer for which enrollment has been suspended. NUC-3373 is currently in a Phase I study for the potential treatment of a wide range of advanced solid tumors and a Phase Ib study for patients with advanced colorectal cancer. Our third ProTide, NUC-7738, is a transformation of a novel nucleoside analog (3’-deoxyadenosine) and is in a Phase I study for patients with advanced solid tumors.
