NuCana Reports Third Quarter 2018 Financial Results and Provides Business Update

Favorable Data Presented at ESMO on NUC-1031 (Acelarin®) and NUC-3373 First Patients Enrolled in Phase Ib Study of NUC-3373 in Advanced Colorectal Cancer Initiation of Phase III Study of Acelarin in Front-Line Advanced Biliary Tract Cancer and Phase I Study of NUC-7738 Expected by End of 2018 EDINBURGH, United Kingdom, Nov. 27, 2018 (GLOBE NEWSWIRE) — NuCana plc (NASDAQ: NCNA) announced financial results for the third quarter ended September 30, 2018 and provided an update on its extensive clinical program with its transformative ProTide™ therapeutics. As of September 30, 2018, NuCana had cash and cash equivalents of £78.4 million compared to £81.5 million as of June 30, 2018 and £86.7 million as of December 31, 2017.  NuCana reported a loss of £2.5 million for the quarter ended September 30, 2018, compared to £14.0 million for the quarter ended September 30, 2017 as the Company continued to advance its various clinical programs.  Basic and diluted loss per share was £0.08 for the quarter ended September 30, 2018, compared to £0.58 per share for the comparable quarter in 2017. “It has been a productive quarter for NuCana highlighted by the data presented at the European Society for Medical Oncology (ESMO) Congress held recently in Munich, Germany,” said Hugh Griffith, NuCana’s Founder and Chief Executive Officer.  “The data presented at ESMO further support the potential of our ProTide technology and its ability to transform some of the most widely prescribed chemotherapy agents into more efficacious and safer treatments.” Mr. Griffith continued: “In our ongoing Phase Ib study of patients with advanced biliary tract cancer, Acelarin® combined with cisplatin continued to show an approximate doubling of the response rate compared to the standard of care.  Furthermore, some patients showed continued tumor shrinkage over time, which is not typically seen in this setting, and a durable progression free survival.  In addition, we presented the latest data for our ongoing Phase I study of NUC-3373, our ProTide transformation of the active anti-cancer metabolite of 5-fluorouracil (5-FU), in patients with advanced solid tumors.  NUC-3373 demonstrated single-agent anti-cancer activity in patients who had exhausted all current standards of care, including three patients who achieved Stable Disease with responses lasting more than nine months at the time of data cut-off.  In addition, NUC-3373 was well tolerated with no cases of hand-foot syndrome, a common toxicity associated with 5-FU.” Mr. Griffith added: “We are delighted by the positive data generated with our first two ProTides, and we look forward to initiating a first-in-human Phase I study by the end of the year with NUC-7738, our third ProTide, which is a transformation of a novel nucleoside analog, cordycepin.  All of this, plus the recent initiation of a Phase Ib combination study of NUC-3373 in patients with advanced colorectal cancer and the expected launch of a Phase III study of Acelarin plus cisplatin in patients with advanced biliary tract cancer, points to 2019 being a very productive year for NuCana.” Anticipated Milestones Acelarin® is NuCana’s ProTide transformation of gemcitabine.  Over the remainder of 2018 and in 2019, NuCana anticipates a number of data read-outs and milestones including:  °  Contingent on regulatory guidance and other factors, initiate a Phase III study of Acelarin combined with cisplatin as a first-line treatment for patients with advanced biliary tract cancer by the end of 2018.  °  Report interim data in 2019 from our ongoing Phase II study (PRO-105) of Acelarin for patients with platinum-resistant ovarian cancer.  °  Contingent on regulatory guidance and other factors, evaluate the initiation in 2019 of a Phase II/III study of Acelarin in combination with a platinum agent for patients with ovarian cancer.  °  Continue enrollment in the Phase III study (Acelarate) of Acelarin as a first-line treatment compared to gemcitabine for patients with metastatic pancreatic cancer. In October 2018, we reported that 152 patients had been enrolled in this study. NUC-3373 is NuCana’s second ProTide in clinical development, a transformation of 5-fluorouracil (5-FU).  In 2019, NuCana expects to:  °  Report initial data from the ongoing Phase Ib study (NuTide:302) of NUC-3373 in patients with advanced colorectal cancer in combination with other approved agents with which 5-FU is typically combined, including leucovorin, oxaliplatin and irinotecan.  °  Report additional data from the ongoing Phase I study (NuTide:301) of NUC-3373 in patients with advanced solid tumors.  °  Contingent on regulatory guidance and other factors, initiate a Phase II/III study of NUC-3373 in combination with other agents for patients with advanced colorectal cancer. NUC-7738 is NuCana’s ProTide transformation of cordycepin, a novel nucleoside analog that has shown potent anti-cancer activity in preclinical studies across a range of different human cancer cell lines.  Over the remainder of 2018 and in 2019, NuCana expects to:  °  Contingent on regulatory guidance and other factors, initiate a first-in-human Phase I clinical study (NuTide:701) of NUC-7738 for patients with solid tumors or lymphoma in 2018.  °  Report initial data from the NuTide:701 study in 2019. 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 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 three clinical studies, including a Phase Ib study for patients with biliary tract cancer, a Phase II study for patients with ovarian cancer and a Phase III study for patients with pancreatic cancer. 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.
