A liposomal delivery composition to be administered through intravenous injection is provided for the treatment of cancer. The delivery composition has a liposome composition with therein encapsulated a first cancer drug (e.g. oxaliplatin) and a second cancer drug (e.g. ascorbic acid or satraplatin). The liposomal delivery composition has negative surface potentials resulting in an encapsulation efficiency for e.g. of oxaliplatin of about 20-25%. The liposomal delivery composition has a particle size of less than 200 nm. The liposomal delivery offers protection of the drug cargo, which reduces their non-intentional and non-pharmacological interactions thus reducing side effects and increases efficacy. Increased efficacy reduces the amount of drug given to a patient, which would reduce healthcare cost. The combinatory approach of two different drug cargos within the same liposome delivery composition allows for the synergistic action of these drugs.
