Effectiveness

How Ritonavir Affects Patients

Ritonavir is a medication used to treat HIV-1. It stops HIV from being able to cut itself into pieces, which stops the virus from reproducing and spreading. Ritonavir must usually be taken with at least two other HIV medications in order to be effective. Additionally, it helps the body absorb more of the other HIV medications, making them more effective.

How Ritonavir works in the body

Ritonavir blocks HIV proteins from being cut apart. Normally, proteins created by HIV are cut into pieces in order to form other proteins, but Ritonavir prevents this from happening. It does this by blocking the enzyme HIV proteinase from working. Ritonavir also stops the transport of other protease inhibitors by interfering with the P-glycoprotein and MRP efflux channels.

When to interrupt dosage

The proposed dose of Ritonavir is contingent upon the ascertained situation, including weight 40 kg or more, HIV (Human Immunodeficiency Virus) and Mild to Moderate COVID-19. The amount of dosage also depends on the mode of delivery (e.g. Oral or Tablet, film coated - Oral), as highlighted in the table beneath.

Ritonavir Toxicity & Overdose Risk

Very little is known about ritonavir overdose in humans. One person experienced tingling sensations after taking 1500mg/day for two days, while another developed kidney failure and an increase in white blood cells. Testing in animals suggests that it would take more than 20 times the recommended dose in humans to cause death in rats, and 10 times the recommended dose in mice. Additional side effects from taking too much ritonavir include liver damage, pancreatitis, and allergic reactions.

Ritonavir for experimental treatment for COVID-19

I started taking this medication when I had my first onset of symptoms for COVID-19 in October 2022. My sister, who was also ill at the same time, did not take the medication. We both saw our conditions improve within a day of each other. I would recommend this medication to anyone looking to limit the worsening of their infection. The only negative effect I experienced was a strong metallic taste, so enjoy your food prior to dosage!

Ritonavir for experimental treatment for COVID-19

After only two days on this medication (four doses), I experienced an intense metallic taste in my mouth and overwhelming fatigue. Additionally, I felt generally unwell and had to take Tums to find relief from the full feeling in my stomach. I called my medical doctor and they advised me to stop taking the medication. The only Covid symptoms I was experiencing were a runny nose and occasional sneezing.

Islatravir + Ulonivirine for HIV

18+
All Sexes
Ft. Pierce, FL

Researchers are looking for new ways to treat HIV-1 (Human Immunodeficiency Virus Type 1). The usual (standard) treatment for HIV-1 is antiretroviral therapy (ART), which includes taking medicines to lower the amount of HIV-1 in the body. Standard ART helps people live longer, but people must take up to 3 medicines up to twice a day. Standard ART may also cause other health problems. Researchers want to know if a study ART works as well as a standard ART to treat HIV-1. The study ART combines 2 medicines, islatravir and ulonivirine, and is taken once a week. The goals of this study are to learn: 1) If the study ART works as well as a standard ART to treat HIV-1, and 2) About the safety of the study ART and if people tolerate it compared to a standard ART.

MucoCept-CVN for HIV Prevention

18 - 45
Female
San Francisco, CA

MucoCept-CVN uses a Lactobacillus strain native to the human vagina that is modified into a live biotherapeutic product (LBP) that continuously expresses a potent anti-HIV drug. If research shows that MucoCept-CVN is safe and effective, it could become a self-renewing, female-initiated prevention product for women that promotes vaginal health and provides protection from HIV. The goal of this first-in-human Phase 1 dose-ranging, randomized, placebo-controlled study of MucoCept-CVN is to collect data on safety, colonization, changes to the vaginal microbiota and clearance of the strain with antibiotics. Twelve healthy women will be enrolled and take either one or three doses of MucoCept-CVN or placebo, and a week later will receive antibiotics to clear the Lactobacillus strain. If research shows that MucoCept-CVN is safe and effective, it could become a self-renewing, long-acting, female-initiated prevention product for women that promotes vaginal health and provides protection from HIV.

Acceptance and Commitment Therapy for Alcohol Consumption in People with HIV

18+
All Sexes
Syracuse, NY

Alcohol consumption is a critical factor in HIV treatment that significantly contributes to poor treatment-related outcomes. Randomized clinical trials (RCTs) of alcohol interventions for people with HIV (PWH) have had limited success, perhaps due to an increasingly recognized co-morbitity of co-occurring hazardous alcohol use and other mental health-related problems among PWH. This has necessitated a shift in the literature towards trans-diagnostic approaches that target core psychological processes that underlie multiple mental health-related problems. One trans-diagnostic mechanism that is relevant to alcohol and other substance use is experiential avoidance (EA)- i.e., repeated, and maladaptive, use of substances and/or other behaviors to escape or avoid unwanted thoughts, feelings, and/or urges. Acceptance and commitment therapy (ACT) targets EA and is an empirically supported treatment for multiple psychological and behavioral health-related outcomes; however there have not been any full-scale RCTs of ACT for alcohol use among any population, including PWH. The investigators recently adapted a telephone-delivered ACT intervention originally developed for smoking cessation, into an intervention for PWH who drink at unhealthy levels (NIH/NIAAA; R34AA026246). This six-session, telephone-delivered ACT intervention for alcohol use showed high feasibility and acceptability in a pilot RCT conducted by our team. The overall objective of this application is therefore to determine if ACT can significantly reduce alcohol use and comorbid symptoms of depression, anxiety, and stress among adult PWH who drink at unhealthy levels. The specific aims are: To determine the relative efficacy of ACT, compared to BI, for reducing alcohol use among PWH (Aim 1) and to determine if ACT has an effect on trans-diagnostic processes that in turn affect alcohol use and other psychological and functional outcomes (Aim 2). The investigators will accomplish these aims by: conducting a remote, RCT in which the investigators randomly assign 300 PWH who drink at unhealthy levels to either the ACT intervention the investigators developed (n = 150), or a BI intervention (n = 150) previously shown to reduce alcohol use among PWH. The investigators will assess alcohol-related outcomes-via self-report and a biomarker- at baseline, post-treatment (7 weeks post-baseline), and again 3-, 6-, and 12-months post-randomization. The investigators will also measure EA to determine if it mediates treatment effects for alcohol use and other psychological and functional outcomes, measured at all timepoints.

The goal of this clinical study is to learn more about the experimental drugs GS-1720 (an oral, long-acting integrase strand transfer inhibitor (INSTI)) and GS-4182 (a prodrug of Lenacapavir (LEN)); to compare the combination of GS-1720 and GS-4182 with the current standard-of-care treatment bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) (Biktarvy), to see if the combination of GS-1720 and GS-4182 is safe and if it works for treating human immunodeficiency virus type 1 (HIV-1) infection in treatment-naive people with HIV-1 (PWH). This study has two phases: Phase 2 and Phase 3. The primary objectives of this study are: Phase 2: To evaluate the efficacy of oral weekly GS-1720 coadministered with GS-4182 versus continuing Biktarvy (BVY) in treatment-naive PWH at Week 24. Phase 3: To evaluate the efficacy of oral weekly GS-1720/GS-4182 fixed-dose combination (FDC) tablet regimen versus continuing BVY in treatment-naive PWH at Week 48.
