What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study collects white blood cells and plasma from 400 people with HIV, including rare 'non-progressors' who control the virus without medication. Researchers will analyze immune responses and genetic markers to understand what makes these individuals special. The goal is to uncover clues that could lead to better treatments or a vaccine.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this research could reveal how certain people naturally control HIV, pointing toward new vaccine or treatment strategies.
What could go wrong
This is an observational study, not a treatment trial. It may not lead directly to new therapies, and findings may not apply to all people with HIV.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

* INCLUSION CRITERIA: 1. Adult (18 years-old or older) 2. Eligibility to undergo apheresis procedures; or, for participants who are unable to undergo apheresis, willingness to undergo blood draw for research purposes that remain within safety guidelines established by NIH policy. 3. Willingness to give informed consent for the storage of blood or tissue samples and HLA testing AND at least one of the following: * An HIV-seropositive participant categorized as an LTNP as defined by clinical and laboratory criteria, regardless of HLA class I type. * HIV-seropositive progressors * Persons who are seronegative for HIV but are family members of seropositive participants exhibiting immunologic control of HIV EXCLUSION CRITERIA: 1. Pregnant 2. Cardiovascular instability, severe anemia, inadequate venous access, severe coagulation disorder, or any other condition that the Principal Investigator or Apheresis Unit staff considers a contraindication to the apheresis procedure or research blood draw. 3.
