Australia has been at the forefront of medical research and innovation, with significant contributions to the field of healthcare. One notable example is the potential discovery of a cure for cancer. In 2016, researchers from Queensland isolated a chemical from an Australian berry that exhibited promising results as a tumor-killing agent. This breakthrough led to clinical trials in animals and humans, although it is important to note that the compound is not a cure-all for cancer and further research is needed. Additionally, Australia has made advancements in understanding the impact of social relationships on physical and mental health, a concept known as the social cure. This theory suggests that belonging to multiple social groups can positively influence well-being, although its effectiveness may vary across different cultures. Australia's history also sheds light on the devastating impact of diseases like smallpox, which had a significant toll on the Indigenous population.

COVID-19 cure using HIV and malaria drugs
In the early days of the COVID-19 pandemic, researchers scrambled to find treatments for the virus. In March 2020, infectious disease experts at the University of Queensland in Brisbane, Australia, believed they had found a cure for COVID-19 using existing drugs. They claimed that a combination of two drugs, chloroquine (an anti-malarial drug) and lopinavir/ritonavir (a combination of HIV-suppressing drugs), had promising results in human tests.
Professor David Paterson, who led the research, said that the drugs made the virus "`disappear`" in infected patients. He explained that the HIV medication lopinavir/ritonavir, when given to people infected with the coronavirus in Australia, led to the "disappearance of the virus". He told an Australian news site: "It's a potentially effective treatment. Patients would end up with no viable coronavirus in their system at all after the end of the therapy."
The HIV-suppressing combination lopinavir/ritonavir is most commonly sold under the name Kaletra. It is an antiviral medication that can be taken twice a day by people infected with HIV to reduce the levels of the virus in the body. This type of drug is called a protease inhibitor, which works by stopping viruses from using an enzyme called protease, which is vital for them to spread.
In addition to the University of Queensland research, doctors in France, the United States of America, and South Korea have used the anti-malarial drug hydroxychloroquine to treat patients with COVID-19. In February 2020, Thailand's health minister claimed its doctors had found a cure for coronavirus, and a combination of swine flu, malaria, and HIV/AIDS drugs has been the most effective treatment so far.
While these drugs have shown promising results in treating COVID-19, it is important to note that there is no specific medicine to prevent or cure COVID-19 infection. The world continues to search for effective treatment options for this disease.

Blushwood berries as a cancer cure
Blushwood berries, found exclusively in the rainforests of Far North Queensland, Australia, have been hailed as a powerful ally in the fight against cancer. The berries, scientifically known as EBC-46, have shown promising results in preclinical trials, demonstrating their ability to destroy cancer cells and inhibit tumour growth.
The potential of blushwood berries in cancer treatment was first recognised when scientists observed that an extract from the tree's berries, traditionally used as an antiseptic for treating wounds and burns, also exhibited anti-tumour properties when tested on animals with melanoma cells. Further research revealed that the compound EBC-46, derived from the berries, could trigger a rapid response in cancerous cells, leading to their destruction within just hours.
In addition to its immediate action against cancer cells, blushwood berry extract has also shown potential as a long-term treatment option without the harmful side effects commonly associated with conventional cancer therapies such as chemotherapy and radiation therapy. Clinical trials have demonstrated that blushwood berry extract is not toxic to healthy cells or beneficial bacteria in the digestive tract, indicating a lower risk of adverse side effects.
While the results of blushwood berry extract have been promising, particularly in animals, it is important to note that the compound has not yet been proven effective in treating metastatic cancers or cancers that have spread to other parts of the body. Additionally, as with any new potential drug, the majority of chemicals that reach the Phase I clinical trial stage for human use do not ultimately make it to market.
Despite these considerations, the discovery of blushwood berries and their remarkable properties offers renewed hope for better and more effective cancer treatments in the future. With further research and development, blushwood berry extract may play a significant role in the ongoing battle against this devastating disease.

Oncolytic viral therapy as a cancer cure
Oncolytic virus therapy is a promising approach to treating cancer. The concept of using viruses to combat tumours dates back to the early 20th century, but it is only recently that we have had the tools to control viral pathogenesis and direct viruses to specific targets.
Oncolytic viruses can be used to infect cancer cells, presenting tumour-associated antigens and activating "danger signals" that generate a less immune-tolerant tumour microenvironment. These viruses can be engineered to decrease their ability to infect healthy cells and to deliver therapeutic payloads specifically to tumours. After infecting tumour cells, oncolytic viruses can cause cancer cells to "'burst", releasing cancer antigens that can stimulate immune responses to seek and eliminate any remaining cancer cells in the body.
One example of an oncolytic virus is T-VEC (Imlygic®), a modified herpes simplex virus that infects tumour cells and promotes their destruction. T-VEC has been approved by the FDA for the treatment of melanoma and has been well tolerated by patients in clinical trials. In one trial, T-VEC was combined with pembrolizumab (Keytruda®), and the combination of the two therapies induced the infiltration of immune cells known as T cells into tumours that had previously lacked them. This suggests that the viral therapy can change the local microenvironment to make an immunologically "cold" tumour into an inflamed, or "hot", tumour.
Oncolytic virus therapy is currently being evaluated in clinical trials, and new platforms and approaches are constantly being developed and investigated. For example, in 2018, a study revealed that treating triple-negative breast cancer patients with oncolytic virus therapy prior to surgery increased their likelihood of responding to checkpoint immunotherapy. Another clinical trial is combining an oncolytic virus and a checkpoint inhibitor in patients with advanced appendiceal cancer, colorectal cancer, and ovarian cancer.

Australian researchers and COVID-19 cure
In March 2020, Australian researchers claimed that they may have found a cure for COVID-19. The researchers, a team of infectious disease experts at the University of Queensland in Brisbane, found that two existing medications, chloroquine (an anti-malarial drug) and lopinavir/ritonavir (an HIV-suppressing combination), managed to wipe out COVID-19 infections in human tests. The drugs were found to make the virus "disappear" in infected patients, and patients responded very well to the treatment.
Professor David Paterson, director of the Center for Clinical Research at Queensland University, expressed optimism about the potential of the drugs as a "treatment or cure" for COVID-19. He noted that when HIV medication was given to infected patients, the virus seemed to disappear, and similar methods were used in the early days of the outbreak in China. However, he acknowledged that more controlled testing was needed to definitively prove the effectiveness of the drugs.
Following the initial findings, Queensland University launched human trials of the two-drug treatment. The researchers received donations from a global appeal to cover the funding costs of the trials, estimated at A$750,000 (US$451,415). The trials were expected to take place across 50 hospitals in Australia, comparing the effectiveness of the individual drugs and their combination.
While the initial results were promising, it is important to note that as of May 2020, the drugs had not yet undergone extensive controlled testing. Professor Paterson emphasized the need for larger-scale pharmaceutical trials to confirm the effectiveness of the treatment.

COVID-19 cure using flu and HIV drugs
In March 2020, Australian researchers claimed to have found a cure for COVID-19 using flu, HIV, and anti-malaria drugs. The University of Queensland Centre for Clinical Research director Professor David Paterson told news.com.au that they had seen two drugs used to treat other conditions wipe out the virus in test tubes. One of the medications, given to some of the first people to test positive for COVID-19 in Australia, resulted in the "disappearance of the virus" and complete recovery from the infection.
The two drugs can be administered orally as tablets and are already manufactured. One of the drugs is an HIV drug, which has been superseded by newer-generation HIV drugs, and the other is an anti-malaria drug called chloroquine, rarely used due to malaria resistance. The HIV drug, Kaletra (also known as Aluvia), is a protease inhibitor that blocks the process the virus would normally use to clone itself and spread the infection further.
The research was sparked by Chinese patients who were first given the HIV drug in Australia. The doctors were surprised and sceptical but saw very positive results. The RBWH Foundation established a Coronavirus Action Fund to raise money for clinical drug trials and other medical research.
Professor Paterson said they wanted to give Australians the best treatment and gain real-world experience. He also said that the data coming from China was not gathered in a controlled way due to the chaos of being the outbreak's epicentre. He added that while the new COVID-19 medicines had successful outcomes in some patients, it had not been tested in a controlled or comparative manner.
The two drugs will be rolled out to 50 hospitals around the country in a clinical trial to treat COVID-19. The hospitals will attempt to determine the best way to use the drugs by comparing one drug versus the other and versus the combination of the two.
