In addition, lithium therapy has been effective in preventing neuronal death and behavioral symptoms in several PD animal models. Recently, our group has shown 24-weeks of low-dose lithium therapy in PD to be associated with improvements in both MRI and blood-based biomarkers implying that lithium may be slowing the progression of the disease. However, these findings stemmed from only three of four patients receiving MRIs. Our group is now conducting two larger studies enrolling a total of 35 PD patients who are being treated with either 45mg\u002Fday or 20mg\u002Fday of lithium or placebo therapy for 24 weeks. Because our earlier study showed maximum improvements in PD biomarkers in patients with serum lithium levels of 0.25-0.50mmol\u002FL and there are large interpatient variations in serum lithium levels achieved from the same lithium dosage, this present study will adjust lithium dosing in each patient to achieve this target serum lithium level for an additional 24 weeks. MRI and blood-based biomarker changes from Baseline will be compared in patients with serum lithium levels ≥ 0.25mmol\u002FL and \\\u003C0.25mmol\u002FL from one of the 24-week studies and within individual patients. Results from this study may identify a target serum lithium level range associated with maximum improvements in PD biomarkers that can be used in the design of future, larger lithium PD lithium trials, which may eventually support lithium as a disease-modifying therapy for PD that could improve patients' long-term prognoses.",[19],"Parkinson Disease",[21,22,23,24],"lithium","biomarker","free water","neurofilament light chain","INTERVENTIONAL","TREATMENT",[28,29],"PHASE1","PHASE2",{"count":31,"type":32},35,"ESTIMATED",[34],{"type":35,"name":36,"description":37,"armGroupLabels":38},"DIETARY_SUPPLEMENT","Lithium aspartate","Lithium aspartate with dosage adjusted to serum lithium level 0.25-0.50mmol\u002FL",[36],[40,44],{"measure":41,"description":42,"timeFrame":43},"Free Water","Change in MRI-assessed free water in posterior substantia nigra, dorsomedial nucleus of the thalamus and nucleus basalts of Meynert.","24 Weeks.",{"measure":45,"description":46,"timeFrame":47},"Serum neurofilament light chain","Change in serum neurofilament light chain","24 weeks",[49,52,55,58,61,64,67,70,73,76,79],{"measure":50,"description":51,"timeFrame":47},"Peripheral blood mononuclear cell (PBMC) Nurr1 mRNA levels by real-time polymerase chain reaction (PCR)","Change in PBMC Nurr1",{"measure":53,"description":54,"timeFrame":47},"PBMC superoxide dismutase 1 (SOD-1) mRNA levels","Change in PBMC SOD-1",{"measure":56,"description":57,"timeFrame":47},"PBMC phosphorylated (p) and total (t) levels of pS9 and total-glycogen synthase kinase 3B (GSK-3B)","Change in PBMC pS9 and t-GSK-3B",{"measure":59,"description":60,"timeFrame":47},"PBMC pThr308, pS473 and t-protein kinase B (Akt)","Change in pThr308, pS473 and t-Akt",{"measure":62,"description":63,"timeFrame":47},"Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Part III","Change in MDS-UPDRS part III scores, Assessed in the \"on\" state.
