Ketamine for MS Fatigue

Early Phase 1

Recruiting

• Conditions: Multiple Sclerosis
• Interventions: Drug: ketamine

• Registration Number: NCT06064162
• Lead Sponsor: Alta Bates Summit Medical Center

Brief Summary

The purpose of this study is to see whether using ketamine to increase glutamate in the prefrontal cortex can reduce Multiple Sclerosis (MS) related fatigue. The investigator proposes a prospective, crossover, randomized, placebo-controlled study to assess the efficacy and safety of low, single dose Ketamine, to assess its efficacy and safety in patients with MS-related fatigue.

Detailed Description

The study treatment is designed in two 28-day cycles: for each cycle, participants will receive study infusion on Day 1 and complete follow-up visits during Days 7 and 28. Participants are randomized 1:1 to receive either ketamine (active treatment) or saline solution (placebo treatment) for their first infusion. They will not be blinded to their study assignment: the study doctor will disclose their assigned treatment group.

After their first infusion cycle, participents will crossover to the other treatment group. Worded differently, if a participant received ketamine during their first infusion, they will receive placebo treatment during their second infusion. Conversely, if a participant received saline treatment during their first infusion, they will receive ketamine during their second infusion.

Arm && Interventions

Group	Intervention	Description
Ketamine (active treatment)	ketamine	dose of 0.5 mg/kg intravenously over 40 minutes on day 1
Saline (placebo treatment)	ketamine	Placebo (saline solution) over 40 minutes on day 1

Primary Outcome Measures

Name	Time	Method
Improve Fatigue Scores	28 days post study drug infusion	a statistically significant change in the level of fatigue score as measured by the Multiple Schlerosis fatigue scales: Modified Fatigue Impact Scale (MFIS) between baseline and day 28 post study drug infusion. Rating scale is 0 to 4 with 0 being "never" and 4 being "almost always."

Secondary Outcome Measures

Name	Time	Method
Improve Quality of Life	Between baseline and day 28	A statistically significant change in the patient's quality of life as measured by Functional Index for Living with Multiple Sclerosis (FILMS) between baseline and day 28. Score is rated 1 to 5 with 1 being "bad" and 5 being "good."
