Tail-PrEP: Safe, guided stopping of long-acting PrEP with coaching and monitoring

Official title: The TAIL-PrEP Study: Acceptability and Feasibility of a Tailored Adherence Intervention for Safe Discontinuation of Long-acting PrEP

Run by Columbia University · NCT06868641 · Data updated 2026-11-12

This study tests whether monthly HIV prevention coaching and drug-level monitoring can help people stop long-acting cabotegravir or switch to safer options without increasing HIV risk.

Is this trial a fit for you?

Likely a good fit

Adults 18 years and older who are HIV-negative, English-speaking, and have internet access, with some arms including those considering or having recently discontinued cabotegravir or lenacapavir.

Probably not a fit

People without access to online coaching or drug-level monitoring, or those not considering discontinuation of long-acting PrEP, may not benefit from this approach.

What this trial studies

TAIL-PrEP explores a practical approach to stopping long-acting HIV prevention injections by using personalized coaching and monthly drug-level checks to support safer discontinuation. The study will pilot two arms: one for people stopping cabotegravir and one for those considering stopping cabotegravir or lenacapavir, with a focus on feasibility and acceptability. Based on findings, the team will refine the intervention and implementation strategy to improve real-world use and public health impact. The goal is to balance stopping injections with maintaining protection against HIV during the tail period after cessation.

Why it matters

Potential benefit: If successful, participants may discontinue long-acting PrEP with structured support that reduces HIV risk during the tail and informs future prevention strategies.

How similar studies have gone: Previous work shows long-acting PrEP strategies require careful tail management; this program tests a novel coaching-plus-monitoring model to improve feasibility.

Inclusion criteria:

* At least 18 years of age
* HIV-negative (self-report)
* Able to speak and read in English
* Have access to an internet-connected device capable of running the online video conferencing platform
* Have a private location at which to take online conference calls

Participants considering discontinuing cab-LA or LEN have the following additional inclusion criteria:

\- Considering discontinuing cab-LA or LEN

Participants discontinuing cab-LA have the following additional inclusion criteria:

* Have discontinued cab-LA injections within the last three months
* Not currently on cab-LA injections
* Able to receive and send monthly packages
* The study period will end for patient participants once the monthly blood draw result indicates that cab-LA levels are not detectable (estimated average of 6 months across all patients) or after 6 months of the study, whichever comes first. If at 6 months of study participation, cab-LA levels are still detectable and participants adhered to at least 50% of study activities (self-collecting and mailing monthly blood samples, completing monthly surveys, attending monthly coaching sessions), participants will be invited to participate in the study for an additional 6 months, for a total of up to 12 study visits.
