Yearly, round 1.5 million persons are contaminated with HIV. This quantity is falling, though not quick sufficient to succeed in a United Nations goal of fewer than 370,000 new infections a 12 months by 2025. Final month’s resolution by the World Well being Group (WHO) to advocate a brand new drug that protects folks in opposition to HIV an infection is a promising growth.

The outcomes of a randomized scientific trial confirmed that the drug cabotegravir (Apretude), taken as an injection six instances a 12 months, is more practical at stopping an infection than is the usual technique of pre-exposure prophylaxis — a each day oral dose of tenofovir disoproxil fumarate and emtricitabine — that’s in use world wide (S. Delany-Moretlwe et al. Lancet 399, 1779–1789; 2022).

The WHO’s suggestion, that cabotegravir is a “secure and extremely efficient HIV prevention device”, opens the best way to together with it in HIV-prevention programmes. Cabotegravir’s producer, ViiV Healthcare in London, has pledged to cost a not-for-profit worth for public programmes within the lowest-income international locations. Chief government Deborah Waterhouse calls it a “game-changing second in HIV prevention”.

Whether or not this seems to be the case is dependent upon whether or not the drug will be rolled out to these most in want, specifically women and girls aged 15 to 24 within the lowest-income international locations. Final 12 months, some 250,000 girls and ladies on this age group have been contaminated with HIV, greater than 80% of them in sub-Saharan Africa. Success would require cabotegravir to be provided on the lowest worth potential. For this to occur, transparency over how the value is calculated is important.

Drug corporations don’t often disclose such calculations, partly due to the necessity for industrial confidentiality. Governments count on to be supplied with information for audit and benchmarking functions, however they don’t publish what they know, both — as Members of the European Parliament (MEPs) found through the COVID-19 pandemic. Though European Union member international locations have spent tens of billions on COVID-19 vaccines and therapies, the suppliers and contracting governments haven’t defined the premise for his or her pricing when requested to take action by MEPs.

In the USA, the industrial worth for cabotegravir has been set at $3,700 per dose (equal to an annual worth of $22,200 per particular person). The not-for-profit worth is but to be made public, but it surely could possibly be considerably much less.

David Ripin, chief scientific officer on the Clinton Well being Entry Initiative, a philanthropic group based mostly in Boston, Massachusetts, has calculated that generics corporations may make cabotegravir for $23 per particular person, per 12 months; this might fall to $16 if scale-up is achieved. These figures are based mostly on including up the price of the lively ingredient, the price of making it into an injectable substance and the price of sterilizing the ensuing product. A abstract of Ripin’s calculations has been printed on-line (see go.nature.com/3bdoa8x).

A 74-strong coalition of campaigners, public officers and researchers that features Winnie Byanyima, the top of the Joint United Nations Programme on HIV/AIDS (UNAIDS), is urging Waterhouse to cost cabotegravir as shut as potential to $60 per particular person per 12 months. That is equal to the quantity governments and philanthropic funders are presently paying for oral pre-exposure prophylactic medicine.

ViiV Healthcare has informed Nature it can’t match this worth, however that it’s dedicated to permitting cabotegravir to be copied by generics producers in order that the drug will be made and distributed rapidly, and that it’s going to cost a not-for-profit worth. These are welcome steps. However the firm may go one higher: let the world know what the value might be and supply a breakdown of the way it was calculated.

Within the meantime, extra researchers may make their very own estimates, which might assist to supply governments and different funders with a benchmark determine for his or her discussions on what to pay. The outlook for additional home and worldwide funding for HIV/AIDS isn’t good, in line with the newest replace from UNAIDS, printed final month (see go.nature.com/3zkhaix). If cabotegravir can’t be provided at a worth akin to or, ideally, decrease than current oral remedies, nations may face some troublesome choices. Members of the general public should know what their governments are paying — and why.
