In March 2020, Australian researchers claimed to have found a cure for the novel coronavirus. The cure was discovered by a team of infectious disease experts at the University of Queensland in Brisbane, who found that two existing medications used to treat HIV and malaria, Chloroquine and Lopinavir, were able to wipe out COVID-19 infections. The researchers planned to conduct a large-scale clinical trial across Australia to test the effectiveness of the drugs, but it is unclear if this took place. While the drugs showed promising results, it is important to note that as of June 2025, COVID-19 is still prevalent in Australia, with over 11 million cases reported.

What You'll Learn
HIV and malaria drugs as a treatment
In the early days of the COVID-19 pandemic, before vaccines were developed, scientists around the world were testing existing medications to see if they could be used to treat the novel coronavirus.
In March 2020, Australian researchers at the University of Queensland in Brisbane claimed that two drugs used to treat HIV and malaria showed promising results in treating COVID-19 infections. The drugs were chloroquine, an anti-malarial drug, and the HIV-suppressing combination lopinavir/ritonavir (also known by the brand name Kaletra). Professor David Paterson, an infectious disease physician, stated that the drugs could be considered a "potentially effective treatment", as they led to the "'disappearance' of the virus" in patients.
The use of HIV medications to treat COVID-19 was particularly surprising to doctors, as this family of viruses had no known treatment. However, the HIV drug lopinavir/ritonavir had previously been tested during the 2003 SARS outbreak, with early studies indicating that the medication was effective in fighting the virus. The combination of lopinavir/ritonavir works by stopping enzymes called proteases from allowing the virus to mature and replicate.
In addition to Australia, doctors in other countries also explored the use of HIV and malaria drugs to treat COVID-19. In Thailand, doctors successfully treated a 71-year-old woman infected with COVID-19 using a combination of anti-viral drugs for flu and HIV. In India, a woman from Italy who was treated in Rajasthan was cured using a combination of HIV, swine flu, and malaria drugs. In the United States, then-President Donald Trump claimed that chloroquine had been approved by the FDA to treat COVID-19, although the FDA later clarified that it had not been approved for this use.
While these early findings were promising, it is important to note that, at the time, Professor Paterson emphasized the need for controlled testing to confirm the effectiveness of these drugs against COVID-19. As of January 2024, there are still no FDA-approved medications to treat or cure COVID-19.

Lopinavir/ritonavir medication
In March 2020, Australian researchers claimed that they had found a cure for the novel coronavirus. The cure was in the form of two drugs: lopinavir and ritonavir, which are typically used to treat HIV. Professor David Paterson, director of the University of Queensland Centre for Clinical Research, said that the drugs led to the "disappearance of the virus" in patients infected with COVID-19. He also stated that it was not a stretch to label the drugs "a treatment or a cure".
Lopinavir/ritonavir is a combination product containing two medications: lopinavir and ritonavir. This product is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in the body so that the immune system can work better. Both lopinavir and ritonavir are protease inhibitors that block a protein called protease from processing viral proteins that allow HIV to infect healthy cells. By blocking protease, lopinavir/ritonavir prevents HIV from making copies of itself and spreading. Ritonavir increases ("boosts") the levels of lopinavir in the body, helping it to work better and longer to fight the infection. The dosage of lopinavir/ritonavir is based on the patient's medical condition, response to treatment, and other medications being taken. It is typically taken by mouth once or twice daily with or without food, as directed by a doctor. For children, the dosage is also based on age and, in some cases, weight and height.
Although serious side effects are rare with lopinavir/ritonavir, patients should contact their healthcare provider if they experience any of the following: severe allergic reactions (such as facial swelling, hives, rash, or itchy skin), serious liver problems (nausea, vomiting, pain in the right side of the stomach), abnormal heart rhythm (chest pain, trouble breathing), or other adverse effects. It is important to note that lopinavir/ritonavir may cause a condition that affects the heart rhythm (QT prolongation), and the risk may be increased for those with certain medical conditions or taking other medications that can cause QT prolongation. Therefore, patients should inform their doctor or pharmacist of all drugs they are taking and any relevant medical history before using lopinavir/ritonavir.

Chloroquine, an anti-malarial drug
In the search for a cure for COVID-19, Australian scientists have found that a combination of HIV and anti-malarial drugs may be effective. In particular, the anti-malarial drug chloroquine has shown promising results in human tests.
Chloroquine was first introduced in 1945 and is considered one of the most important 4-aminoquinolones, a class of compounds that belong to the broader group of antimalarial drugs, 4-amino quinolines. The development of chloroquine can be traced back to the synthesis of Resochin (chloroquine) and Sontochin (3-methyl-chloroquine) by German scientists in 1934. These compounds were created in an attempt to find a substitute for quinine, which was first introduced in 1632 and was the primary treatment for malaria until the introduction of chloroquine.
The use of chloroquine as a potential treatment for COVID-19 was initially suggested after Chinese patients in Australia responded positively to the drug. Professor David Paterson, an infectious disease physician and director of the University of Queensland Centre for Clinical Research, stated that chloroquine led to the "disappearance of the virus" in infected patients. He emphasized that it could be considered a "potentially effective treatment" and that there were no unexpected side effects.
The success of chloroquine in treating COVID-19 may be attributed to its ability to stop the virus from reproducing and infecting new cells. This mechanism of action is believed to be crucial in combating the coronavirus. Furthermore, the drug has a history of being well-tolerated, which makes it a promising candidate for further investigation.
While the initial results with chloroquine are encouraging, Professor Paterson highlights the need for controlled testing and larger clinical trials to confirm its effectiveness as a cure for COVID-19. The University of Queensland team aims to conduct trials across 50 hospitals in Australia, comparing the effectiveness of different drugs and their combinations.

Chinese patients in Australia
In March 2020, Australian researchers claimed to have found a cure for the novel coronavirus. The cure was discovered by a team of infectious disease experts at the University of Queensland in Brisbane. They found that two existing medications used to treat HIV and malaria—chloroquine and the HIV-suppressing combination lopinavir/ritonavir—were able to wipe out COVID-19 infections. According to Professor David Paterson, the director of the University of Queensland Centre for Clinical Research, one of the medications had already been administered to some of the first people to test positive for COVID-19 in Australia, resulting in the "disappearance of the virus" and complete recovery from the infection.
The discovery of this potential cure was influenced by the experiences of Chinese patients in Australia. Professor Paterson noted that the first wave of Chinese patients they treated with the HIV drug "did very, very well". This initial success with Chinese patients in Australia contributed to the exploration and eventual discovery of this potential cure.
The Chinese community in Australia played a crucial role in sharing information and recommendations during the early stages of the COVID-19 outbreak. They relayed stories of successful treatments from mainland China and Singapore, which prompted Australian researchers to investigate further. This exchange of knowledge highlights the global collaboration that occurred during the quest to find effective treatments for COVID-19.
While the treatment showed promising results in some patients, it is important to note that, at the time, there hadn't been any controlled testing as would be required for a new drug. Professor Paterson emphasized the need for a large-scale clinical trial across Australia, involving 50 hospitals, to compare the effectiveness of different drugs and their combinations. The researchers expressed confidence in their ability to move forward rapidly with enrolling Australians in the trial.
The potential cure generated hope and sparked further efforts to combat the virus. Researchers planned to share their findings with the World Health Organization (WHO) to contribute to global diagnosis and treatment initiatives. The discovery also led to fundraising efforts, such as the establishment of the Coronavirus Action Fund by the RBWH Foundation, to support clinical drug trials and related medical research.

Clinical trials across Australia
Clinical trials are an essential step in the development of new treatments and cures for diseases. In the context of the COVID-19 pandemic, Australia has been at the forefront of conducting clinical trials to find effective treatments and cures for the novel coronavirus.
In March 2020, researchers at the University of Queensland in Brisbane announced that they had seen promising results with two existing medications: Chloroquine, an anti-malarial drug, and the HIV-suppressing combination lopinavir/ritonavir. These drugs were found to wipe out COVID-19 infections and lead to the "disappearance of the virus" in infected patients. Professor David Paterson, an infectious disease expert, stated that these drugs could be considered a "treatment or cure" and that a large-scale clinical trial across Australia was needed to confirm their effectiveness.
The proposed clinical trial would involve 50 hospitals across Australia, comparing the effectiveness of one drug versus another, or a combination of the two drugs. The researchers emphasized the urgency of conducting these trials and were confident in their ability to rapidly enroll participants. The RBWH Foundation established a Coronavirus Action Fund to support these clinical drug trials and related medical research, reflecting the importance placed on finding effective treatments for COVID-19.
While the research response in Australia has been rapid, with numerous clinical trials launched, better coordination and collaboration are imperative. The unpredictable nature of the pandemic, low case numbers in Australia, and the challenge of recruiting participants have impacted the conduct of trials. Additionally, duplication of efforts and underpowered trials have been identified as issues that need to be addressed through improved coordination and evidence synthesis.
Despite these challenges, Australia's contribution to the global effort to find treatments and cures for COVID-19 through clinical trials is significant. The country's researchers and medical community have played a crucial role in the fight against the pandemic, and their efforts have provided hope and potentially life-saving treatments for people affected by the virus.
