Combination of [6R]-methylenetetrahydrofolate with multi-targeting antifolates to reduce their toxicity while treating cancer

摘要

The use of tetrahydrofolate, methylene-tetrahydrofolate and/or methyl-tetrahydrofolate, and at least one multi-targeting antifolate, for the manufacture of a pharmaceutical composition for the treatment of cancer is disclosed. By combining the multi-targeting antifolate with tetrahydrofolate, methylene-tetrahydrofolate and/or methyl-tetrahydrofolate, it is possible to remarkably reduce toxic side-effects without diminishing the anti-tumour action of the drugs. A pharmaceutical composition, a kit comprising the pharmaceutical composition as well as a method for the treatment of cancer are also disclosed.
