Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Some people with Amyotrophic Lateral Sclerosis (ALS) have a high level of the virus HERV-K in their blood. Researchers do not think this virus causes ALS. But they don t know why some people with ALS have a high level of it. They want to know if HERV-K can be suppressed by drugs that are used to treat HIV infection. Objectives: To learn how drugs usually taken for HIV infection affect people with Amyotrophic Lateral Sclerosis (ALS). Eligibility: Adults at least 18 years old with ALS and high levels of HERV-K but no HIV. Design: Interested participants can contact the study team and, if eligible, the study team will arrange for a screening blood draw to determine the HERV-K level. Participants with a high HERV-K level will be screened with medical history, physical exam, questionnaires, nerve conduction test, lumbar puncture, and blood and breathing tests. After screening, participants will start taking the 4 study drugs. Participants will have up to 12 study visits over a period of 72 weeks. After starting study drugs, they will have study visits at Weeks 1 and 4 and then every 4 weeks until Week 28. They will be asked how they are feeling and have an exam and blood drawn. At 3 visits, they will have tests of nerve conduction, breathing, and their ALS symptoms. At Week 24, they will stop taking the study drugs and may have a repeat lumbar puncture. After the Week 48 visit, their participation is finished.
