Evaluated "on demand" PrEP with Truvada versus placebo arm. The drug regimen involved taking Truvada in the 24-hour period before anticipated sex and then, if sex happened, two separate one-pill doses in the two days following sex. After the discontinuation of the placebo arm in October 2014, the study continued as open-label until the end of June 2016.
