About NuCana
NuCana is a clinical-stagebiopharmaceutical 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 effectiveand 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.Utili
zing 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'spipeline 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.
NUC-3373
is currently being evaluated in three ongoing clinical studies: a Phase 1b/2 
study (NuTide:302) in combination withleucovorin, irinotecan or oxaliplatin, 
and bevacizumab in patients with metastatic colorectal cancer; a randomized 
Phase 2 study (NuTide:323) in combination with leucovorin, irinotecan, and 
bevacizumab for the second-line treatment of patients withadvanced colorectal 
cancer; and a Phase 1b/2 modular study (NuTide:303) of
NUC-3373
in combination with the
PD-1
inhibitor pembrolizumab for patients with advanced solidtumors and in 
combination with docetaxel for patients with lung cancer.
NUC-7738
is a transformation of 3'-deoxyadenosine, a novel anti-cancer nucleoside analog.
NUC-7738
is in the Phase 2 part of a Phase 1/2 study in patients with advanced solid 
tumors which is evaluating
NUC-7738
as a monotherapy and in combination withpembrolizumab.
