Medical researchers in Spain are testing whether HIV medication Truvada, often used as PrEP, can also help treat Covid-19.
Spain has been one of the hardest hit countries in the Covid-19 pandemic, with one in 10 deaths reported to be from the healthcare community, and the study will focus on whether healthcare workers could take Truvada, along with a range of other interventions, to prevent them getting Covid-19.
The study is led by Plan Nacional sobre el Sida, the Spanish National AIDS Plan, and began on April 1 for an initial period of 12 weeks.
Truvada consists of two drugs, tenofovir disoproxil fumarate and emtricitabine, and has long been a part of highly effective combination therapies for people living with HIV. It is also used by some HIV-negative people as pre-exposure prophylaxis, or PrEP, soon to be made widely available across the National Health Service.
The Spanish study will enrol 4,000 participants randomised into groups taking one of a range of single-dose daily regimens. Initial results are expected to be published in late July/August.
