This new medical drug will enter the final stage of trials, and it is expected that it will treat those in the "last stages" of skin cancer, and they have weeks to die.
The way Xantrin works means it is a "world first" and there is hope it could be used to help thousands of patients with 25 different types of cancer.
The company, "Res Oncology", said that it will start clinical trials of the drug for the treatment next year 2022 and in cooperation with a team from Newcastle University, led by the chief skin cancer researcher Professor Xu Dong Zhang.
The drug "Xantrin" has been neglected for 15 years, as it was a chemotherapy drug in the eighties, before it lost its importance in the world and was hoarded in warehouses.
But researchers have discovered a new use for it today, which makes it a very important drug for cancer patients.
The drug will be used, along with other immunomodulatory drug treatments, to attack the "envelope" of a cancer cell, killing its ability to "hide" from the immune system.
The drug's main task is to stimulate the immune system to work, killing melanoma cells and producing "unexpected" cures in patients who are told they have only weeks to live.
