PrEP: The Pathway to Global Access

TAGline Fall 2015

Regulatory filing and review delays keep Truvada as pre-exposure prophylaxis out of reach of those who need it most

By Scott Morgan

Pre-exposure prophylaxis (PrEP) is the use of antiretroviral medication to prevent HIV acquisition. The U.S. Food and Drug Administration has approved only one medication as PrEP, in July 2012: a co-formulation, of tenofovir disoproxil fumarate (TDF) with emtricitabine (FTC), manufactured by Gilead. While early uptake in the United States was decidedly slow, education and promotion have increased demand in some vulnerable communities. Yet around the globe, for the majority of people who need or desire PrEP as part of a complete prevention package, the medication is not affordable without regulatory approval and inclusion in national health programs.

The originator company, Gilead, has filed for regulatory approval for Truvada in only five additional countries (see table). In some countries, steps are being taken to include PrEP in national strategic plans and to issue guidance for health care providers, yet the onus remains on the originator or generic drug manufacturers to file for regulatory approval. And, depending on the country, the time from submission to approval can be over a year.  

In South Africa, the first national PrEP guidelines for men who have sex with men at high risk for HIV infection were published in 2012. These guidelines are reportedly being updated to include populations beyond this group, yet the country’s regulatory agency, the Medicines Control Council (MCC), is not demonstrating urgency in approving PrEP. As South Africa has the highest HIV incidence globally, this snail’s pace has frustrated activists, clinicians, and scientists alike.

Without regulatory approval, there are still ways to get PrEP in some countries, particularly those hosting demonstration projects or open and enrolling PrEP trials. PrEP is also available off-label where TDF/FTC has been approved for treatment, such as the United Kingdom, at discounted—but still prohibitively expensive—prices. In Thailand, the Thai Red Cross AIDS Research Center provides PrEP for roughly US$1 per day; in Australia unregulated TDF/FTC can be purchased on the Internet for personal use at around US$313 for a 90-day supply. Yet, given the scope of the epidemic, it’s clear that these mechanisms are meeting the needs of only a fraction of people in high-risk groups. And they don’t include regular HIV testing and other necessary laboratory tests.

If we are to use all our evidence-based tools to eliminate new infections, there needs to be a coordinated effort among activists, manufacturers, and regulatory agencies to accelerate and streamline approval of PrEP so that individuals around the world can more fully control their sexual health.•
