Unveiled Secrets: The Mark Smyth Nelistotug Scandal and Australia’s Research Crisis, By Brian Simpson
A celebrated scientist. A promising cancer drug. Millions in public funds. These were the pillars of Professor Mark Smyth's illustrious career, until allegations of fabricated data shattered his reputation and exposed deep flaws in Australia's scientific research system. The Mark Smyth Nelistotug scandal, centred on falsified research underpinning a drug now in clinical trials, has sparked outrage among cancer patients, researchers, and taxpayers, while igniting urgent calls for reform. I explore the scandal's origins, its impact on cancer research, and the systemic failures that allowed misconduct to fester, revealing a crisis that threatens Australia's scientific integrity.
Professor Mark Smyth was once Australia's most cited immunologist, a fellow of the Australian Academy of Science, and a leader in cancer immunotherapy. Over three decades, he secured over $42 million in public funding, including $38 million from the National Health and Medical Research Council (NHMRC), and published over 400 papers. His work at the Peter MacCallum Cancer Centre (2000–2013) and QIMR Berghofer Medical Research Institute (2013–2021) focused on harnessing the immune system to fight cancer, earning him accolades like the Coley Medal.
Central to Smyth's legacy was Nelistotug, a drug developed by GSK that aims to boost immune responses against cancer. Smyth's lab claimed a key discovery behind its development, cited in six of the patent's 42 studies. However, in 2021, QIMR Berghofer's investigation, led by retired judge Robert Gotterson, found Smyth guilty of "serious research misconduct," including data fabrication in grant applications and clinical trial support. This revelation, coupled with retractions in top journals like Nature Immunology and Journal of Clinical Oncology, has cast doubt on Nelistotug's foundation and Smyth's entire body of work.
Nelistotug, now in human clinical trials, is tainted by the scandal. One of the six studies cited in its patent was retracted for fabricated data, prompting two co-authors to express fears that the drug may not work as intended. One, anonymously stated, "I felt like the project must have been based on fabricated data," emphasising the ethical breach for patients expecting effective treatment. GSK insists its processes are sound, and no direct harm to trial participants has been reported, but the inclusion of falsified data raises serious concerns about the drug's reliability and the trust of patients enrolled in trials.
The scandal's roots trace back to Smyth's lab practices. Whistleblowers at QIMR Berghofer reported healthy mice in experiments supposedly involving cancer cells and captured videos of Smyth discarding viable samples. A 2016 melanoma study, claiming success with antibodies in mice, was retracted in 2023 after investigators concluded the experiments likely never occurred. These findings suggest Smyth's results, including those supporting Nelistotug, were often "too good to be true," with suspiciously uniform data.
The scandal extends beyond Smyth's actions to systemic failures at his institutions. A 2023 review by former Federal Court judge Bruce Lander found QIMR Berghofer ignored complaints about Smyth for seven years, partly due to his "celebrity" status and fundraising prowess. Six researchers raised concerns but were ignored or disrespected, and QIMR lacked a research integrity office until 2018.
Earlier, at Peter MacCallum Cancer Centre, colleagues flagged issues in 2014, leading to a preliminary investigation that found a case to answer. Yet a University of Melbourne inquiry cleared Smyth, a decision now criticised as insufficiently rigorous. These missed opportunities allowed Smyth to continue unchecked, highlighting a broader issue: Australia's self-regulatory research integrity system, where institutions investigate their own staff, creates conflicts of interest. Former Science Minister Kim Carr, who designed the system, admitted in 2025, "It clearly no longer works," citing the pressure to protect institutional reputations.
The financial toll is staggering. QIMR Berghofer repaid $3.4 million in grants, and Smyth's $42 million in funding, including $38 million from NHMRC, is now seen as partly wasted. Taxpayers and cancer survivors feel betrayed, as funds meant for life-saving research supported fraudulent work. The public's trust in Australian science, particularly cancer immunotherapy, a field where Australia has been a leader, has been eroded, potentially delaying legitimate treatments.
The scandal also raises ethical questions about Nelistotug's clinical trials. Patients were not informed of whistleblower concerns or the retracted study, undermining informed consent. While GSK maintains safety protocols, the reliance on Smyth's data risks misdirecting resources and hopes.
The Smyth scandal exposes deep flaws in Australia's research oversight. The self-regulatory model, where universities and institutes handle misconduct allegations, prioritises reputation over rigour. Lander's report noted that QIMR's delay in addressing complaints stemmed from Smyth's status, a pattern seen in earlier clearances at Melbourne. Whistleblowers faced bullying or career risks, discouraging future reports.
Critics, including Professor David Vaux and former NHMRC head Warwick Anderson, advocate for an independent research integrity watchdog, similar to the U.S. Office of Research Integrity, to oversee investigations and protect whistleblowers. The Australian Research Integrity Committee exists but cannot investigate allegations directly, only review institutional processes. In July 2025, the government announced a review of the system, spurred by the Smyth case, but no concrete reforms have emerged. Senator Peter Whish-Wilson called an independent body a "no-brainer," proposing a private member's bill if needed.
The Mark Smyth Nelistotug scandal is a wake-up call for Australian science. Smyth's fabricated data, enabled by institutional inaction, has squandered millions, undermined cancer research, and betrayed public trust. The reliance on a flawed self-regulatory system allowed misconduct to persist, highlighting the need for an independent watchdog to ensure transparency and protect whistleblowers. As Nelistotug trials continue, patients and researchers deserve clarity on the drug's validity. This crisis, rivalling Australia's worst scientific scandals, demands urgent reform to restore faith in a field meant to save lives. The secrets unveiled in Smyth's lab must lead to accountability, not just for one scientist, but for a system that failed to stop him.
