NuCana Announces First Patients Enrolled in Phase Ib Study of NUC-3373 in
Advanced Colorectal Cancer
NuTide:302 Study Will Evaluate NUC-3373 in Combination with Other Agents Typically
Administered with 5-FU
Edinburgh, United Kingdom, November 1, 2018 (GLOBE NEWSWIRE) NuCana plc (NASDAQ: NCNA) announced the first patients have been enrolled in the
NuTide:302 Study. This study is evaluating NUC-3373 in combination with other agents typically administered with 5-fluorouracil
(5-FU) in patients with advanced colorectal cancer. NUC-3373 is NuCana s ProTide transformation of the active anti-cancer metabolite of 5-FU.
The NuTide:302 study was preceded by the
first-in-human Phase I study (NuTide:301) of single-agent NUC-3373 in patients with advanced solid tumors. Initial results from
NuTide:301 were presented in October 2018 at the European Society for Medical Oncology (ESMO) Congress in which NUC-3373 was observed to have had durable single-agent anti-cancer activity in patients who had
exhausted all current standards of care. Furthermore, NuCana believes NUC-3373 demonstrated potential safety and dosing administration advantages as compared with 5-FU.
In that study, three patients achieved durable Stable Disease with responses lasting more than nine months at the time of data cutoff. Both dosing regimens were observed to be well tolerated with no unexpected adverse events (AEs). Of particular
note, no patients developed hand-foot syndrome, a common and debilitating side effect of fluoropyrimidine treatment.
Hugh Griffith, NuCana s Chief
Executive Officer, stated: NUC-3373 is our second product candidate developed from our proprietary ProTide technology. The goal, as with all our ProTides, is to significantly improve the efficacy and
safety of commonly used anti-cancer agents. We believe NUC-3373 has the potential to replace 5-FU as the standard of care in the treatment of a wide range of cancers and
we are pleased to have enrolled the first patients in this combination study.
NuTide:302 is a two-part
study of NUC-3373 administered every two weeks as an intravenous (IV) infusion. In part 1, NUC-3373 will be combined with leucovorin, with a plan to enroll 12
patients. In part 2, NUC-3373, with or without leucovorin, will be studied in separate combinations with oxaliplatin, oxaliplatin plus bevacizumab, oxaliplatin plus panitumumab and irinotecan, and irinotecan
plus cetuximab, with six patients planned per cohort. The primary objective of the study is to identify a recommended dose of NUC-3373 in combination with standard agents used in treating advanced colorectal
cancer. The study will also make a preliminary assessment of the anti-tumor activity of the combinations.
More information about this study may be found
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.
