Keytruda is an immunotherapy medicine that helps the body use its own immune system to fight certain cancers including Hodgkin Lymphoma.
The potentially life-saving cancer medicine that patients must self-fund at a cost of more than 200-thousand dollars, is being made available on prescription.
The move brings down the cost to less than forty-dollars, every three weeks.
It's one of five new drugs added to the Pharmaceutical Benefits Scheme.
