Japan govt. disposes of expired oral coronavirus drugs for 2.5 million people
Japan's health ministry says oral COVID-19 drugs for about 2.5 million people were disposed of after passing their expiry dates. Based on the special anti-virus law, the government purchased three types of oral coronavirus drugs to treat about 5.6 million people. It supplied them for free to medical institutions and pharmacies through May 2023, when the government downgraded COVID-19 to the same level as the seasonal influenza. The health ministry says PaxlovidPACK for about 1.75 million people and Lagevrio for about 780,000 people were disposed of by the end of February. The ministry also says that Xocova for about 1.77 million people is expected to be discarded by the end of July next year. The ministry says it has considered ways to utilize the drugs. However, officials decided to dispose of them after considering how their supply for free could impact the drug market. The ministry explains that the purchase was made to ensure the provision of coronavirus medication for people needing them, as their initial supply was limited.

About 1.75 million doses of Pfizer's Paxlovid were discarded by November, along with roughly 780,000 doses of Lagevrio from Japanese Merck arm MSD by February, the Ministry of Health, Labor and Welfare reports.

COVID antivirals are heavily marketed. It's not clear how well they work
Observational studies of the drugs included in the analysis concluded that the drugs halve the risk of hospitalisation, but the researchers are concerned that the results might be biased by differing trial designs. Generally, scientists look to randomised controlled trials for gold-standard evidence. New Zealand stopped subsidising Lagevrio in 2024 due to concerns about its effectiveness. Australia's COVID-19 Evidence Taskforce recommends against using the drug, which costs $1102 a pack. Despite that, Australian doctors gave out 315,000 scripts last year, plus another 243,000 for Paxlovid. Lagevrio and Paxlovid were the fifth and ninth-most-expensive drugs to taxpayers in 2023-24. The taskforce only recommends Paxlovid for unvaccinated people. It offers a limited recommendation for those who have been vaccinated but are elderly and have multiple risk factors, while noting the evidence is 'unclear'. 'In our systematic review, there were no randomised controlled trials conducted in vaccinated people since 2022 that reported a benefit from COVID-19 antivirals against hospitalisation or death,' said Dr Laura Edwards, a researcher at the University of NSW who led the study. 'It is timely to re-evaluate whether the cost we are paying for these drugs is appropriate.' It is plausible that the drugs may be useful for a small cohort of extremely high-risk people, who are elderly and have multiple risk factors, says Cheng. But this group is rarely enrolled in medical trials, making it difficult to work out the true efficacy. Loading 'I'm not entirely sure there's much benefit in that group. But there probably isn't any harm done by it.' Dr Gideon Meyerowitz-Katz, a senior fellow at the University of Wollongong, has published an analysis of Paxlovid's cost-benefit. He said there was evidence of a small reduction in hospitalisation risk, making the drug still worth subsidising. 'I think that Australia has a very reasonable, pragmatic approach, prioritising high-risk individuals who will benefit and not paying for low-risk people who probably won't.' In a statement, Pfizer pointed to the first study of Paxlovid, which demonstrated an 86 per cent reduction in the risk of hospitalisation or death: 'Real-world data collected during the Omicron period among high-risk populations who have received COVID-19 vaccinations reinforce the effectiveness of Paxlovid in preventing hospitalisations and deaths.' MSD, which sells molnupiravir, said it stood behind the drug. The Department of Health said both antivirals were under review by the Pharmaceutical Benefits Advisory Committee, with results expected mid-2026. Lagevrio and Paxlovid work by stopping the virus that causes COVID-19 from multiplying in our cells, theoretically giving the immune system a leg up against it. The first studies by the drug companies found the two pills cut the risk of hospitalisation or death by about 50 per cent and 89 per cent respectively in unvaccinated people. Loading But Lagevrio's 50 per cent effectiveness was only seen in a study that stopped halfway. When the full trial was analysed, whether it offered any benefit at all became debatable. A large independent study in 2022 also found it was likely no better than a placebo. A study published by Pfizer last year concluded Paxlovid's protective effect in vaccinated patients, including those at high risk, was so small as to not be statistically significant. That study began in 2021 but was only published in 2024. Research conducted by the Grattan Institute late last year found that wealthier Australians were far more likely to be prescribed COVID antivirals than those at the bottom of the income ladder, despite people living in disadvantage typically having much greater risk factors for severe disease. 'Essentially, like so many things in our healthcare system, the treatments and services weren't going to the people who need them most,' said Peter Breadon, the Institute's health program director. Nearly all Australians have either been vaccinated or survived a COVID-19 infection, meaning there is less benefit from antivirals. And the Omicron variant is less likely to hospitalise or kill a patient than the preceding Delta variant. 'COVID is a different disease to what it was,' said Cheng, who is now director of infectious diseases at Monash Health. '[Patients] don't get pneumonia and lung white-out, generally. It's almost like we're doing a study in a different disease, which is making it difficult to work out how relevant … what we found out early on [is] to what we know now.' This stark difference shows up in Pfizer's studies of Paxlovid. In Pfizer's first study, involving unvaccinated people, 7 per cent of patients given a placebo ended up in hospital and 13 died. In the second study, which involved vaccinated people, just 1.6 per cent of the placebo group were hospitalised. 'For young, fit and healthy people, antivirals are not going to do much. You're at pretty low risk,' said Cheng. 'For older people – those over 65 or 70 – or people who have other medical issues, that's one they should go and see their GP.'
