The Evidence for Contraceptive Options and HIV Outcomes Trial

The ECHO Study is an open-label randomized clinical trial that will compare three highly effective, reversible methods of contraception (including a non-hormonal method) to evaluate whether there is a link between use of any of these methods and increased risk of acquiring HIV infection. A randomized clinical trial among about 7,800 women in four countries, ECHO will deliver evidence to support and guide individual, policy and programmatic decisions on contraception for women at risk of acquiring HIV infection.
