Early Effects of Ketamine vs Placebo With... — Clinical Trial Details

Randomised, quadruple-blind, parallel-group Phase III trial in hospitalized adults with severe unipolar MDE (HDRS ≥24) comparing three IV ketamine infusions (0.5 mg/kg on Days 1, 4 and 7) versus matching saline placebo, both given adjunctive to venlafaxine.

Primary aim is to assess early antidepressant effects and safety; an ancillary PET-MRI study using [11C]UCB-J will assess synaptic density changes in a subset, with additional imaging-specific eligibility criteria.

Contraindications to [11C]UCB-J PET-MRI
1. Absolute contraindications: Pacemaker or neurosensorial stimulator or implantable defibrillator; clip on a brain aneurysm or vascular malformation; intraocular or intracerebral ferromagnetic foreign body; prostheses or objects or mobile ferromagnetic metal fragments; cochlear implants; peripheral stimulator; neurosurgical ventriculoperitoneal shunt valves; automated injection device such as insulin pump, glucose sensor; permanent eyelid or lip makeup; non-removable piercing; claustrophobia.
