One 12 months in the past, the United States authorised a brand new injectable drug that stops HIV.
After profitable scientific trials, long-acting cabotegravir was discovered to be nearly 100 per cent efficient at stopping HIV. It was authorised within the U.S. on Dec. 20, 2021, to be used as HIV pre-exposure prophylaxis (PrEP). This approval signifies that eligible people can now obtain this treatment each eight weeks to forestall sexually-acquired HIV an infection.
However this new drug, which might assist handle among the ongoing challenges with HIV prevention for individuals who stay at excessive danger, remains to be not obtainable in Canada.
HIV in Canada
The variety of new HIV infections has not modified a lot over the previous couple of many years and roughly 13 per cent of individuals dwelling with HIV in Canada are undiagnosed. This demonstrates the necessity for extra HIV prevention methods.
While long-acting injectable PrEP is new, oral PrEP — a tablet taken both each day or round sexual exercise — was authorised within the U.S. again in 2012. Canada solely authorised oral PrEP in 2016. And we’re as soon as once more falling behind the U.S. on making injectable PrEP obtainable right here.
Oral PrEP already reduces the danger of HIV by nearly 100 per cent when taken persistently, however current scientific trials present that injectable PrEP is much more efficient. The important benefit of injectable PrEP is that going for injections each two months is quite a bit simpler to recollect than taking capsules daily, or taking capsules earlier than and after sexual exercise. The swap from oral capsules to injectable photographs signifies that people can extra simply preserve adherence, which impacts the general effectiveness of PrEP as HIV prevention.

Although some individuals may desire capsules to photographs for varied causes, injectable PrEP offers another choice, and other people like having totally different HIV prevention choices obtainable to them. At the person degree, injectables imply extra decisions. At the inhabitants degree, extra decisions imply extra prevention as a result of totally different individuals is perhaps prepared to make use of totally different sorts of PrEP to go well with their wants.
Contraception analysis has additionally demonstrated the significance of increasing individuals’s treatment choices. Injectable contraceptives spotlight how this know-how improves each sexual and reproductive well being.
Oral PrEP is usually in contrast with the contraception tablet. There is a necessity to higher perceive how new injectable choices for each contraception and HIV prevention have an effect on adherence, entry and the relationships of those that use them.
Both injectable and oral PrEP are protected and extremely efficient and so they every have only a few side-effects. Injectable PrEP has gentle injection web site reactions, together with swelling, redness and ache.
There are additionally a number of different new HIV PrEP choices which are nonetheless being studied in scientific trials, together with thrilling long-acting oral, injectable, implantable and infusion choices which are administered at totally different time intervals and will match the totally different schedules and preferences of individuals concerned with HIV prevention.
Preparing for prevention
We might be prepared for these new developments by studying from our previous experiences with the approval and implementation of earlier HIV prevention methods, like oral PrEP. Some people and communities nonetheless face limitations to PrEP, like entry to health-care suppliers who’re educated about it, and these limitations can perpetuate well being inequalities.
Our analysis challenge, The Future of PrEP is Now, focuses particularly on neighborhood readiness for long-acting injectable PrEP as a result of it has the potential to assist overcome earlier limitations to PrEP. Oral PrEP can nonetheless be inaccessible, costly and stigmatized for many individuals in Canada and the one-pill-a-day adherence might be particularly difficult.
Communities of Two-Spirit, homosexual, bisexual, queer and different males who’ve intercourse with males (2SGBQM) are nonetheless disproportionately affected by HIV, and HIV charges are usually not declining in Canada. 2SGBQM are additionally under-reached by current PrEP packages, particularly those that are Indigenous, Black, individuals of color, rural, individuals who use substances, transgender and non-binary.
In our analysis, we discuss to members of under-reached communities of 2SGBQM in addition to the health-care suppliers who serve them to:
study their preferences concerning future long-acting injectable PrEP choices
assess the feasibility of varied fashions of delivering injectable PrEP
design a nationwide examine of injectable PrEP that responds to the wants and priorities of people already experiencing limitations to oral PrEP.
In a current public webinar, we requested “the place are we going?” with PrEP as we plan for a long-acting injectable choice to change into obtainable in Canada within the close to future. We need to make sure that when this new therapy is authorised, long-acting PrEP is rapidly obtainable and as equally accessible as oral PrEP to those that will profit from it essentially the most. Raising consciousness and constructing help for this new HIV prevention technique will assist meet these objectives.
