Study Summary

This trial will study whether a combination of two drugs, islatravir and lenacapavir, is effective in suppressing HIV in people who are already virologically suppressed.

Who is the study for?
This trial is for people with HIV who have maintained a viral load of less than 50 copies/mL and have been on B/F/TAF treatment for at least 24 weeks. They shouldn't have had previous virologic failures, exposure to ISL or LEN, serious infections within the last month, hepatitis B or C co-infections, low kidney function or certain low blood cell counts.Check my eligibility
What is being tested?
The study tests the effectiveness of taking Islatravir (ISL) orally once a week combined with Lenacapavir (LEN) in those whose HIV is already under control. The goal is to see how well this combination works after 24 weeks compared to their current treatment.See study design
What are the potential side effects?
While specific side effects are not listed here, common side effects from HIV treatments like ISL and LEN may include nausea, headache, fatigue, and potential liver issues. Side effects can vary based on individual health conditions.

Trial Design

2Treatment groups
Experimental Treatment
Group I: ISL+LENExperimental Treatment2 Interventions
Participants will receive the following for at least 48 weeks: Day 1: LEN oral 600 mg (2 x 300 mg) and ISL 2 mg (2 x 1 mg) Day 2: LEN only oral 600 mg (2 x 300 mg) Day 8 and weekly thereafter (ie, every 7 days): LEN oral 300 mg (1 x 300 mg) and ISL 2 mg (2 x 1 mg)
Group II: B/F/TAFExperimental Treatment3 Interventions
Participants will receive the following for at least 48 weeks: bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) 50/200/25 mg once daily After 48 weeks, participants will switch from B/F/TAF to ISL+LEN Day 1: LEN oral 600 mg (2 x 300 mg) and ISL 2 mg (2 x 1 mg) Day 2: LEN only oral 600 mg (2 x 300 mg) Day 8 and weekly thereafter (ie, every 7 days): LEN oral 300 mg (1 x 300 mg) and ISL 2 mg Participants who do not switch from B/F/TAF to ISL+LEN at Week 48 will be discontinued from the study.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Could you provide a synopsis of the other experiments which have utilized ISL technology?

"Presently, there are 98 clinical trials investigating ISL. Of these studies, 22 have advanced to Phase 3 of the trial process. The majority of research is based in Boylston, MA but that accounts for just a fraction of the 1,609 sites running experiments with this drug."

Answered by AI

Does ISL pose any risk to patients when administered?

"There is some evidence of ISL's safety, so it obtained a rating of 2. However, there has yet to be any data collected on its efficacy."

Answered by AI

How many participants have been recruited for this clinical experiment?

"At this present moment, the clinical trial is not accepting participants. It was first listed on October 5th 2021 and updated lastly on July 12th 2022. However, for those still searching for a study to join, there are 106 trials with HIV-1 patients being recruited and 98 studies looking into ISL presently taking partipants."

Answered by AI

Are there still vacancies in this clinical trial open to participants?

"This clinical trial has already ceased participant recruitment, with its first posting on October 5th 2021 and last edit taking place July 12th 2022. For those looking for similar studies, there are 106 trials involving human immunodeficiency virus type 1 (hiv-1) infection that are actively recruiting as well as 98 ISL related projects seeking volunteers."

Answered by AI

What are the primary applications of ISL as a medication?

"HIV-positive patients who have not been exposed to any antiretroviral therapy, and lack resistance to darunavir can all receive treatment in the form of ISL."

Answered by AI

Are there numerous locales currently conducting this experiment in the state?

"Peter Shalit, M.D., Floridian Clinical Research and Community Research Initiative of New England are amongst the 24 trial sites sponsoring this project in Seattle, Miami Lakes and Boston respectively."
