NCT03821233
This is a first-in-human, Phase 1, multicenter, open-label, dose-escalation study to establish the maximum-tolerated dose (MTD) or recommended dosage (RD) of ZW49, the investigational agent under study, and to assess the safety and tolerability of ZW49. Eligible patients include those with locally advanced (unresectable) or metastatic HER2-expressing cancers.
NCT06069843
Ketamine is a NMDA-receptor antagonist that promotes synapse formation and has been shown to rapidly improve symptoms in depression. Even a single dose of ketamine has been shown to improve depression and cognition with short-term memory, inhibitory control, cognitive flexibility, and processing speed showing improvements within days of treatment. The mechanism behind ketamine's rapid action is not clear but some groups have speculated it may be related to enhanced neuroplasticity, particularly in the frontal areas and the hippocampus. If this mechanism is accurate, ketamine may be especially effective in treating mild cognitive impairment and depression (MCI-D) where changes in the hippocampus and frontal areas have been implicated. Although few studies have been published on the effects of ketamine in older adults, some small pilot studies suggest that ketamine treatment might be effective in improving depression in older adults and relatively safe. There are no studies looking at the effects of ketamine treatment in patients with MCI-D. The research team hypothesize that IV ketamine treatment will be well-tolerated and will improve depression and cognition in patients with MCI-D. The study team will explore the effects of brain imaging abnormalities and amyloid biomarker status on the responsiveness to ketamine. The study team will conduct an open-label pilot study designed to gather data to support an application for a larger NIH-funded study.
