Welcome to PURPOSE 3

Everyone deserves to be able to protect themselves from HIV.

When it comes to HIV prevention, many cisgender women have not considered HIV PrEP (pre-exposure prophylaxis) as an option for themselves. Despite a decline in HIV incidence in women in the United States, approximately 18% of new HIV diagnoses in the US in 2021 were among women. We want to find more options for women to protect themselves against HIV. PURPOSE 3 will help to understand if an investigational PrEP medicine, lenacapavir, can be used by cisgender women in the US to help prevent acquiring HIV through sex.

PURPOSE 3 was designed to support cisgender women in the US in HIV prevention.

Second, this is a chance to help change how medical research is done.

Cisgender women, specifically Black and/or Latina women, have been historically underrepresented in HIV clinical trials. It's time to change that. We are committed to fair inclusion in PURPOSE 3, so that what we learn can benefit all.
