Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

This phase two, single-site study will utilize a double-blind, placebo-controlled, randomized, pre-/post-treatment design to investigate the effect of NAC dosing on brain GSH levels and measure temporally concordant plasma levels of several established circulating markers of oxidative stress. Three study groups, of 20 subjects each (for a total of 60 who completed all components of the study), will each be administered a different dose (0 mg/day, 900mg/day, 3600mg/day) of the study intervention over a four week period; N-acetylcysteine (NAC) treatment. Subjects receiving 0 mg/day dose will be administered a placebo. Baseline visit assessments will include blood collection, survey questionnaires, MRI and MRS imaging. Subjects whose initial screening confirms low GSH level at baseline will be provided with a 4-week supplement of anonymized NAC or placebo caplets. After 4 weeks, subjects will then undergo a follow-up visit to repeat the baseline assessments.
Active Comparator: NAC 900mg/day
Subjects who pass screening may be randomly assigned to this arm where they will self administer NAC 900mg/day caplets for a four week period
Active Comparator: NAC 3600mg/day
Subjects who pass screening may be randomly assigned to this arm where they will self administer NAC 3600mg/day caplets for a four week period
Placebo Comparator: NAC 0mg/day (Placebo)
Subjects who pass screening may be randomly assigned to this arm where they will self administer NAC 0mg/day (placebo) caplets for a four week period
Drug: - NAC 900mg/day
self administer NAC 900mg/day caplets for a four week period
Drug: - NAC 3600mg/day
self administer NAC 3600mg/day caplets for a four week period
Drug: - NAC 0mg/day (Placebo)
self administer NAC 0mg/day (placebo) caplets for a four week period
