Rapid Uptake of Pre-Exposure Prophylaxis After Significant Price Reduction in Germany Highlights Importance of Pre-Exposure Prophylaxis Accessibility.

Pre-Exposure Prophylaxis (PrEP) has been widely accepted as an effective method to prevent HIV infections, but high costs precluded a widespread use in Germany. A novel distribution pathway of tenofovir-disoproxil fumarate and emtricitabine PrEP was implemented, which reduced monthly PrEP costs by 16-fold in Germany. Over a period of 6 months, we recorded prescription data, demographics, and sexual behavior of PrEP users, including self-reported sexually transmitted infections (STIs), alcohol and drug use. Within a month, prescriptions almost doubled from 585 to 1,009 and reached a cumulative number of 6,059 at the end of the 6-month observation period. Extrapolation of the data suggests an estimated maximal number of PrEP users of the order of 10,000. PrEP users demonstrated to be a population of well-educated men (407/686) who have sex with men (629/686), median age 38 (range:18-71), and of German descent (571/686). The majority used PrEP to compensate for risk of HIV infection when having condomless anal intercourse (372/686). At start of PrEP implementation, the majority perceived their own risk to acquire HIV as none to medium (78.6%;  = 539), while only a subset (18.8%;  = 129) considered themselves to be at high or very high risk for HIV infection. In contrast, within the last 6 months, 28.4% of the PrEP users had an STI diagnosis and over 70% had condomless anal intercourse with more than 6 partners. Taken together, our data from PrEP implementation in Germany demonstrate a large uptake once it became affordable in individuals who wish to compensate for HIV risk when having condomless anal intercourse.
