Definitions
- the present invention relates to a pharmaceutical composition for preventing or treating cancer comprising vaccinia virus and hydroxyurea as active ingredients.
- Anti-cancer virus has excellent tumor-specific targeting ability, proliferation ability in cancer cells, and cancer cell killing ability, and a variety of clinical studies based on anti-cancer viruses are recently being conducted.
- T-Vec talimogene laherparepvec
- an anticancer virus based on the herpes simplex virus in the United States and Europe as a treatment for advanced melanoma.
- vaccinia virus-based anticancer viruses after anticancer virus treatment, acute tumor necrosis, durable response, or complete response may appear, but sometimes tumor progression (progressive disease). ) Or early death, leading to unpredictable outcomes (pharmacodynamics variability).
- Pexa-vec which is based on vaccinia virus, it is related to continuous systemic inflammatory response and organ dysfunction after anticancer virus treatment in a phase 1 clinical trial. Some patients died prematurely within a month.
- transient flu symptoms (high fever) and hypotension after anti-cancer virus treatment are the most frequent adverse reactions of anti-cancer virus treatment.
- the present inventors studied to enhance the anticancer effect of vaccinia virus used as an anticancer virus.
- vaccinia virus and hydroxyurea are co-administered to an individual with cancer, when only the existing vaccinia virus is administered. It can be used safely by significantly reducing systemic inflammatory reactions.
- vaccinia virus is administered systemically, when hydroxyurea is administered in combination, the present invention has been completed by confirming that the cancer cell-specific selectivity and proliferation ability are excellent.
- an aspect of the present invention provides a pharmaceutical composition for treating cancer comprising vaccinia virus and hydroxyurea as active ingredients.
- Another aspect of the present invention provides a method for treating cancer comprising administering vaccinia virus and hydroxyurea to an individual suffering from cancer.
- Another aspect of the invention provides the use of a composition comprising vaccinia virus and hydroxyurea for preventing or treating cancer.
- Another aspect of the present invention provides the use of a composition comprising vaccinia virus and hydroxyurea for preparing a medicament for preventing or treating cancer.
- Another aspect of the present invention provides an anticancer adjuvant comprising hydroxyurea as an active ingredient.
- the pharmaceutical composition for cancer treatment comprising vaccinia virus and hydroxyurea of the present invention as active ingredients has superior anticancer effect and safety compared to the case of administering only the existing vaccinia virus. Therefore, the pharmaceutical composition comprising the vaccinia virus and hydroxyurea of the present invention as active ingredients can be usefully used to treat cancer.
