An interventional study of Cidofovir and Probenecid in HIV Infections and Leukoencephalopathy, Progressive Multifocal, sponsored by National Institute of Allergy and Infectious Diseases (NIAID). Completed at 19 sites in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2021-10-29.

The purpose of this study is to evaluate the safety, tolerance, and overall effectiveness of cidovir to treat PML in AIDS patients.
PML is an opportunistic infection (HIV-associated, due to weak immune system) caused by a virus that attacks the brain. Cidovir has been used effectively to treat cytomegalovirus (CMV) of the eye. Cidovir could be an effective treatment for PML as well.
PML is a demyelinating disease of the brain's white matter, occurring when the JC virus infects the brain of patients infected with HIV-1. Cidofovir is known to be an effective treatment for cytomegalovirus of the eye and, in laboratory and animal testing, has also been shown to be effective against several other viruses. However, cidofovir is considered investigational as a treatment for PML.
In this multicenter, open-label study 24 patients receive cidofovir iv over 1 hr on days 0, 7, then every 2 wk for a total of 13 doses.
Oral probenecid is given 3h prior to and 2h and 8h following cidofovir administration. Nucleoside and non-nucleoside reverse transcriptors are withheld on days of probenecid administration. Protease inhibitors are continued during probenecid administration.
3,035 studies on the registry are indexed under Acquired Immunodeficiency Syndrome; 306 are open to participants now.
This study's enrollment of 24 is below the median of 96 across 2,251 interventional studies indexed under Acquired Immunodeficiency Syndrome.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
