NCT ID: NCT05537935 Suspended - Clinical trials for Human Immunodeficiency Virus

Low Dose Naltrexone for Pain in Patients With HIV

Start date: April 28, 2023
Phase: Phase 4
Study type: Interventional

The increased life expectancy of Patients Living With HIV/AIDS (PLWHA) has increased the need for therapies for chronic conditions, such as chronic pain. Pain in the HIV population is often refractory and ends up being treated with chronic opioids, which are associated with adverse effects, including hyperalgesia, constipation, and risk of overdose. Naltrexone is an opioid antagonist used in the treatment of alcohol and opioid use disorders. Low Dose Naltrexone (LDN), naltrexone at a much lower dose, is thought to be an immune modulator and has been associated with an increased CD4 count in PLWHA. Repurposing this medication is relatively inexpensive, and has the potential to expand access to treatment for a painful condition experienced in PLWHA. While there are many case reports on the efficacy of LDN in symptom reduction, there are only a small number of clinical trials that specifically examine pain and symptom relief. This study will include patients who are not completely virologically controlled and will monitor the CD4 counts drawn as a part of routine care. If the CD4 count improves with LDN and with reduced symptoms, this could be a significant improvement in HIV therapy for symptom control. There have been studies showing cytokine reduction in fibromyalgia patients but they did not investigate the correlation with cytokines and pain relief. This study involves repurposing of a drug used for substance use disorder to a medication with the potential to treat pain and improve symptoms for PLWHA.

Baricitinib for Reduction of HIV - CNS

Start date: May 18, 2023
Phase: Phase 2
Study type: Interventional

There is still no cure for the human immunodeficiency virus (HIV). While combination antiretroviral therapy (cART) is effective in decreasing deaths from HIV, infected individuals face a lifetime of treatment and many potential complications including end organ diseases such as HIV-associated neurocognitive disorders. HIV infection is controllable with antiretroviral therapy (ART), but ART cannot eliminate HIV reservoirs. Thus, there is no available cure for HIV. There is a large and growing body of evidence that the central nervous system (CNS) is an HIV reservoir site and a barrier to HIV eradication. Our group has done extensive pre-clinical work with janus-kinase (JAK 1/2) inhibitors. This includes baricitinib, which is an orally available, FDA-approved drug for rheumatoid arthritis. Evidence suggests that this drug has activity against HIV in the central nervous system (CNS). In our recently completed pilot study, we showed that baricitinib crosses the blood brain barrier (BBB) and decreases HIV CNS persistence in the brain. Using bloodwork, neurocognitive testing, MRIs and lumbar punctures, we plan to evaluate the change in central nervous system HIV after treatment with baricitinib versus placebo. We will also evaluate changes in neuroimaging, inflammation in blood and cerebrospinal fluid (CSF), and neuropsychological performance after treatment with baricitinib versus placebo. Evidence shows that the central nervous system is one of the reservoir sites that enables the HIV virus to persist in the body even after years of treatment. In order to attack this reservoir and eventually find a cure, it is vital to learn if certain medications can suppress HIV in the CNS.
