About

KetaPal is a placebo-controlled randomized trial designed to demonstrate the antidepressant action of ketamine in palliative care situations. Half of participants will receive Ketamine and Milnacipran in combination, while the other half will receive a Placebo and Milnacipran in combination.

Full description

Ketamine, a molecule mainly used as an analgesic in palliative care, turns out to be an excellent fast acting antidepressant. By acting as an NMDA receptor antagonist, its mechanism of action is complementary to classical and long acting antidepressants like Selective Serotonin Reuptake Inhibitors (SSRI). In particular, ketamine is able to boost synaptogenesis in only a few hours whereas long-term prescription of SSRI can stimulate neurogenesis.

The purpose of this study is to evaluate a new therapeutic strategy that could integrate ketamine in the same time than SSRI, to control depression symptoms faster and optimize patient's quality of life complementary to treatments of cancer.
