Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ketamine
Ketamine Hydrochloride
Ketamine will be administered by a nurse in a 2-week treatment phase, during which participants will receive six IV infusions of 0.5 mg/kg (over 40-50 minutes) ketamine three times per week. Infusion days for patients will be on Mondays, Wednesdays, and Fridays, +/- 1 day. Ketamine infusions will take place at the UMB General Clinical Research Center (GCRC). The GCRC nurse will deliver ketamine within a private exam room. The infusions will last 40-50 min, and the participant will be observed by the GCRC clinical staff for 2 hours post-infusion. Vital signs will be monitored throughout the treatment; specifically, blood pressure, pulse ox and heart rate will be checked prior to treatment, q20 minutes during infusion, and q30-60 minutes after infusion for up to three hours.
