简要总结
To explore the safety, feasibility and net symptomatic effects of multiple (3x/week, for 4 weeks) intermittent hypoxia treatment sessions in individuals with PD. Secondary outcomes include exploring induction of relevant neuroprotective pathways as measured in serum.
详细描述
Intermittent hypoxia therapy is a non-pharmacological intervention used by athletes and individuals with cardiovascular disease, amongst others. The safety and feasibility of (intermittent) hypoxia therapy and its short-term effects on Parkinson's disease (PD) symptoms were assessed in a previous exploratory phase I trial. However, the net effects of multiple hypoxia treatment sessions on PD symptoms are unknown. The results of the previous phase I trial informed the study design of the newly proposed phase 1b-2a safety and efficacy trial.
45 minutes of normobaric intermittent hypoxia (FiO2 0.16 for 5 minutes interspersed with 5 minutes normoxia) will be delivered via a hypoxicator (a device that titrates decreased fractional oxygen from room air) through an oxygen mask in the hospital and subsequently at participants' homes. Interventions will be conducted 3 times a week, for 4 weeks in total.
