A Clinical Study of Ixazomib to Reactivate HIV and Reduce HIV Reservoir Size

A Phase 2, Double-Blinded, Randomized, Placebo-Controlled Trial of Ixazomib to Reactivate HIV and Reduce HIV Reservoir Size

This study tests whether a medicine called ixazomib is safe for people living with HIV, and whether it can wake up HIV that is hiding in the body so the immune system and treatment can reach it.

HIV can stay hidden inside cells even when antiretroviral therapy (ART) keeps the virus under control. These hidden cells are called the HIV reservoir, and they are the reason HIV is not cured by ART alone. Laboratory research suggests ixazomib may reactivate hidden HIV and also help kill the cells that carry it. Ixazomib is already approved to treat a cancer called multiple myeloma and has been given to a smaller group of people with HIV in an earlier study.

About 45 adults with HIV that is well controlled on ART will take part. Participants are assigned by chance to take either ixazomib or a placebo - a capsule with no active medicine - one capsule by mouth once a week for a total of 25 doses. Two out of every three participants receive ixazomib and one out of three receives placebo. Neither participants nor the study staff know which one a participant is taking.

Everyone continues their own HIV treatment throughout the study.

Participation lasts about 7 months: 24 weeks of weekly capsules and 4 more weeks of follow-up after the last dose. Participants come to the clinic for about 14 visits, and take their capsule 24 to 36 hours before each visit so blood samples can show the effect of the dose.

The main purposes of the study are to evaluate whether ixazomib is safe and tolerable, and to measure whether it increases the very small amounts of HIV in the blood compared with placebo. The study also measures the size of the HIV reservoir and how the immune system responds.

研究概览

详细说明

A5420 is a phase 2, double-blinded, randomized, placebo-controlled trial of ixazomib in adults with HIV-1 who are virologically suppressed on antiretroviral therapy. Forty-five participants will be randomized 2:1 to ixazomib 4 mg or matching placebo, taken orally once weekly for a total of 25 doses over 24 weeks, while continuing their own suppressive ART. Randomization is stratified by sex (male/female) using permuted blocks to balance enrollment across arms. Participants are evaluated at screening, entry (week 0), and weeks 1, 2, 3, 4, 6, 8, 10, 12, 16, 20, and 24, with a post-treatment evaluation at week 28 following a 4-week washout, for approximately 14 visits over roughly 7 months.

Study treatment is administered as a single 4 mg capsule taken with water on an empty stomach, at least 1 hour before or 2 hours after food, on the same day and at approximately the same time each week. Capsules are not broken, chewed, or opened. Doses preceding a clinic visit are taken 24 to 36 hours before that visit so that plasma and cell-associated virologic measurements capture the post-dose interval.
