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 choice by the World Well being Group (WHO) to advocate a brand new drug that protects individuals in opposition to HIV an infection is a promising improvement.
The outcomes of a randomized medical 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 every 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 “protected and extremely efficient HIV prevention software”, 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 nations. Chief govt Deborah Waterhouse calls it a “game-changing second in HIV prevention”.
Whether or not this seems to be the case is determined by whether or not the drug could be rolled out to these most in want, particularly women and girls aged 15 to 24 within the lowest-income nations. Final 12 months, some 250,000 girls and women 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 worth is calculated is important.
Drug corporations don’t often disclose such calculations, partly due to the necessity for business confidentiality. Governments count on to be supplied with knowledge for audit and benchmarking functions, however they don’t publish what they know, both — as Members of the European Parliament (MEPs) discovered during the COVID-19 pandemic. Though European Union member nations have spent tens of billions on COVID-19 vaccines and therapies, the suppliers and contracting governments haven’t defined the idea for his or her pricing when requested to take action by MEPs.
In the US, the business 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, however it 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 might 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 energetic 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 revealed on-line (see go.nature.com/3bdoa8x).
A 74-strong coalition of campaigners, public officers and researchers that features Winnie Byanyima, the pinnacle of the Joint United Nations Programme on HIV/AIDS (UNAIDS), is urging Waterhouse to cost cabotegravir as close as possible to $60 per person per year. That is equal to the quantity governments and philanthropic funders are at present paying for oral pre-exposure prophylactic medication.
ViiV Healthcare has told Nature it cannot match this price, however that it’s dedicated to permitting cabotegravir to be copied by generics producers in order that the drug could be made and distributed shortly, and that it’s going to cost a not-for-profit worth. These are welcome steps. However the firm might go one higher: let the world know what the worth will probably be and supply a breakdown of the way it was calculated.
Within the meantime, extra researchers might 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 keeping with the most recent replace from UNAIDS, revealed final month (see go.nature.com/3zkhaix). If cabotegravir can’t be provided at a worth akin to or, ideally, decrease than present oral remedies, nations might face some tough choices. Members of the general public should know what their governments are paying — and why.
