In some people, these symptoms continue for months or longer and can substantially affect daily activities. Currently, there are no approved treatments that specifically target these symptoms.\n\nAripiprazole is a medicine that is approved to treat certain psychiatric disorders. At low doses, it may affect brain signaling and immune processes that are thought to contribute to symptoms experienced by people with PAIS. Small observational studies have suggested that low-dose aripiprazole may improve symptoms such as fatigue and cognitive impairment in people with related conditions, but its effectiveness and safety have not yet been confirmed in a randomized controlled trial.\n\nThe purpose of this study is to evaluate whether low-dose aripiprazole is safe and more effective than placebo in improving fatigue and other neuropsychiatric symptoms in adults with PAIS.\n\nThis is a phase 2b, randomized, double-blind, placebo-controlled crossover trial. Approximately 138 participants with PAIS will be enrolled. Participants will be randomly assigned to one of two treatment sequences. One group will receive low-dose aripiprazole for 8 weeks followed by placebo for 8 weeks. The other group will receive placebo first, followed by low-dose aripiprazole. The two treatment periods will be separated by a 2-week washout period. Neither the participants nor the study team will know which treatment is being given during each treatment period.\n\nThe primary objective is to determine whether low-dose aripiprazole improves fatigue after the first 8-week treatment period compared with placebo. Fatigue will be assessed using the Chalder Fatigue Questionnaire. Secondary objectives include evaluating the effects of treatment on physical functioning, quality of life, memory and cognitive performance, mood, post-exertional malaise, illness-related anxiety and distress, and fatigue in participants who meet diagnostic criteria for myalgic encephalomyelitis\u002Fchronic fatigue syndrome (ME\u002FCFS). Safety will be assessed throughout the study by monitoring adverse events.\n\nThe results of this study may help determine whether low-dose aripiprazole is a safe and effective treatment option for people with PAIS",[84,85],"Post-acute Infectious Syndrome (PAIS)","Post-COVID-19 Condition (PCC or Long COVID)",[87,88,89,90],"PAIS","Long COVID","Fatigue","Cognitive deficits","NOT_YET_RECRUITING","2026-07-15",{"date":94,"type":95},"2026-07-20","ACTUAL",{"date":97,"type":78},"2026-10-01",{"date":99,"type":78},"2028-12-31",{"name":64,"class":6},1]
