As reported in the
New York Times (
see here) the Centers for Disease Control (CDC) recommended Wednesday that hundreds of thousands of Americans at risk for AIDS take Truvada, a daily pill that has been approved by the FDA for "PrEP," pre-exposure (to HIV infection) prophylaxis, for gay men who have sex without condoms.
Participants in a clinical trial (iPrEX) who consistently took Truvada reduced their risk of HIV infection by more than 90 percent (99 percent among those whose blood samples showed drug concentrations consistent with daily use).
This should be good news for patients at risk of HIV infection as well as for Gilead, which markets the drug in the U.S. According to the
NYT article, CDC's recommendation could mean a 50-fold increase in the number of prescriptions for Truvada — to 500,000 a year from fewer than 10,000. The drug costs $13,000 a year, and most insurers already cover it.
But there's a catch. Many AIDS advocates such as the AIDS Healthcare Foundation (AHF) are afraid that widespread use of Truvada to prevent HIV infection will encourage unsafe sex (e.g., sex without condoms) leading to other problems.
AHF also cites survey results that revealed possible adherence problems - such as unwillingness to pay the $60 per month estimated co-pay for the drug and medical tests required as well as fear of side effects.
On the Truvada website, Gilead has answers to these issues -- such as coupons to cover the co-pay costs of the drug and free condoms.
Gilead, however, needs to go beyond a drug.com website to get the message out. In fact, this sounds like a problem tailor-made for a mass-media (TV and print) direct-to-consumer advertising solution! But Gilead has no plans to advertise Truvada for prophylaxis, even though the FDA approved it for that use back in 2012.
Why not?
Not advertising helps Gilead avoid controversy, says the
Times reporter. But I contend that in this case not advertising is itself controversial considering that Truvada is 99% effective in preventing HIV infection and that based on the "number needed to treat" data, Truvada is FOUR TIMES more likely to save lives than statins, another widely promoted preventive drug regimen (see chart above).
If Gilead decides to advertise Truvada for prophylaxis, I have some recommendations.
