Effectiveness

How Malarone Affects Patients

Atovaquone is a fat-soluble drug that is similar in structure to ubiquinone. It works by targeting certain processes in parasites, such as energy production and the creation of a certain type of molecule. Atovaquone has been found to target a specific part of the energy making process in the parasite Plasmodia. Unlike many drugs, atovaquone does not cause bone marrow suppression, making it a good choice for those who have had a bone marrow transplant.

How Malarone works in the body

We don't know exactly how atovaquone works to fight Pneumocystis carinii, but it appears to target enzymes involved in energy production in cells. This inhibition stops the cells from being able to make nucleic acid and ATP, which causes them to die. Atovaquone is also effective against Toxoplasma gondii when tested in a lab.

Malarone for Prevention of Falciparum Malaria

I took this drug for many trips to Papua New Guinea and Solomon Islands. The trips varied from one week up to four weeks. I never experienced any side effects and took this drug for a total of around 6 months over a 3 year period. [I tried an alternative anti-malarial when I ran out of Malarone on one trip - hydroxycloroquine - and had continuous stomach upsets and diarrhoea.]

Malarone for Prevention of Falciparum Malaria

I took the drug for 16 days before I went to Africa. I don't think it had any effect; I got mosquito bites regardless. Additionally, both of my legs now have weird rashes on them that don't itch, so I'm stopping the medication early.

Malarone for Prevention of Falciparum Malaria

My experience with this medication was fine, but my boyfriend had a very different reaction. He started feeling faint and lightheaded, and his vision kept going in and out. This went on for about an hour before he finally fell asleep. Needless to say, he won't be taking this again.

Malarone for Prevention of Falciparum Malaria

Malarone gave me terrible diarrhea four days into my trip to Tanzania. The doctor at the lodge said it was because of the Malarone and had me stop taking it. I had to take a lot of imodium for the rest of my trip and even when I got back home.

Antibodies for HIV

18 - 55
All Sexes
Birmingham, AL

This study is testing a lab-made antibody called ePGT121v1-LS that targets a specific part of HIV. Researchers will give it by vein (IV) and under the skin (SC), both on its own and together with two other antibodies, VRC07-523LS and PGDM1400LS, which target different parts of the virus. They will assess safety and side effects, determine the right dose, study how the body processes the drug (pharmacokinetics or PK), and measure how well it neutralizes HIV in the blood (serum neutralizing activity). The expectation is that ePGT121v1-LS, whether given alone or with PGDM1400LS and VRC07-523LS, by IV or SC, will be safe in generally healthy adults and that the antibodies will not interfere with each other when used together. Approximately 83 volunteers in overall good health and without HIV-1 will be enrolled into two parts (A and B). Part A has six groups. In Groups 1-3, participants will get ePGT121v1-LS given by IV at one of three dose levels: 5 mg/kg, 20 mg/kg, or 40 mg/kg. In Groups 4-6, participants will receive three antibodies-first ePGT121v1-LS, then PGDM1400LS and VRC07-523LS-given by IV at two separate visits that are 24 weeks apart. The total study duration for participants in Part A is 48 weeks of scheduled clinic visits. Part B has two groups. In Group 7, people will get ePGT121v1-LS as SC shots at two visits 12 weeks apart. Each visit will give a total of 375 mg, split into three injections of 125 mg each. In Group 8, people will also have two visits 12 weeks apart and will receive three antibodies as SC shots in this order: first ePGT121v1-LS (125 mg), then PGDM1400LS (100 mg), and then VRC07-523LS (100 mg). The total study duration for participants in Part B is 24 weeks of scheduled clinic visits.

AI-DBT for Suicide Prevention in HIV/AIDS

18+
All Sexes
Newark, NJ

One in four older persons living with HIV/AIDS (PLWHA) report at least one suicide attempt in their lifetime, and the risk for death by suicide is 100 times higher in PLWHA than in the general population. Currently, there are no behavioral interventions that specifically address suicide prevention for older PLWHA, despite their unique biopsychosocial and structural risk factors. Through this work, investigators will adapt Dialectical Behavior Therapy, an evidence-based intervention for suicide prevention, for patients with PLWHA to be delivered by an AI-powered conversational Agent developed by our industry partner, Empower Health. Investigators will then pilot test the feasibility, usability, acceptability and preliminary efficacy to improve self-efficacy to manage negative emotions in n=50 older adults living with HIV/AIDS.

Montreal, Canada

The HOW LONG trial is an international, multicenter, Phase IV randomized clinical trial evaluating the optimal duration of adjunctive systemic corticosteroids in immunocompromised adults with severe Pneumocystis jirovecii pneumonia (PCP) who demonstrate early clinical recovery. Participants who no longer require supplemental oxygen by day 10 of corticosteroid therapy are randomized to discontinue corticosteroids at day 10 (or hospital discharge, if earlier) versus continue corticosteroids for a total of 21 days. The trial assesses whether earlier discontinuation reduces steroid-related complications while maintaining clinical outcomes.

The goal of this study is to examine two types of olfactory interventions (olfactory training vs overnight odor diffuser) in adults with HIV. The two research questions are: 1. Determine if participants find the intervention acceptable and assess feasibility of the study. 2. Determine if the intervention improves olfactory function and cognitive function. Participants will come to our office and be administered the baseline battery of questions including olfactory and cognitive performance tests. Then they will be randomized and sent home with one of the two interventions (below) in which they will engage in it for 8 weeks, after which they come back to our office for the posttest battery of questions including olfactory and cognitive performance test. 1. Olfactory Training at Home -- 4 scents in which they will smell twice a day for 8 weeks. 2. Overnight Diffuser Group -- a single scent diffuser that participants will turn on while they sleep and use for 8 weeks.

Decision Support Tool for HIV Treatment

18+
All Sexes
Los Angeles, CA

This study is testing software designed to help healthcare providers choose the best HIV treatment combinations for their patients. HIV medicines, known as antiretroviral therapy (ART), can be complex to manage because the right regimen depends on many factors-such as drug resistance, other health conditions, and medication schedules. Many people with HIV are cared for by general clinicians who may not have access to HIV specialists, which can make treatment decisions more challenging. In this study, healthcare providers will use patient cases to compare standard HIV treatment resources with a new clinical decision support tool that gives evidence-based ART recommendations at the point of care. The investigators hypothesize that using the tool will help providers select treatment plans that better match clinical guidelines, make decisions faster, reduce mental effort, and increase overall satisfaction with the prescribing process.

MGD020 + MGD014 for HIV

18 - 65
All Sexes
Chapel Hill, NC

This research study aims to find out how safe and well tolerated the experimental study drugs are when given to persons with HIV (PWH) taking antiretroviral therapy (ART). The study treatments are MGD014 and MGD020, which are two antibodies developed specifically for HIV, and Vorinostat, an oral medication to help expose HIV in cells to the antibodies. The study will measure the impact of study treatment on non-active HIV in cells, and how long MGD014 and MGD020 stay in the body after they are given. In this study, participants will be randomly assigned to one of three groups. All participants receive MGD014 and MGD020, given sequentially as infusions through an IV for 4 doses. Participants in one group (group A) receive only MGD014 and MGD020. Participants in another group (group B) will stop taking their ART therapy for up to 8 weeks (a temporary treatment interruption (TTI)) while receiving MGD014 and MGD020. Participants in the third group (group C) receive Vorinostat in addition to MGD014 and MGD020. Total time of participation is about 8 months and involves 13 or 18 visits, depending on group assignment.
