Brief Summary: Background

Major depressive disorder MDD is a serious mental illness that can put people at risk of self-harm and death Many drugs are used to treat MDD but it can take a long time for them to be effective Researchers want to know if a faster-acting drug 2R6R-hydroxynorketamine HNK can better treat the symptoms of MDD

Objective

To test a study drug HNK in people with MDD

Eligibility

People aged 18 to 70 years with MDD They must have had a screening assessment under protocol 01-M-0254

Design

Participants will be tapered off their current MDD drugs over 2 to 5 weeks They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures They will have a physical exam with blood tests They will have tests of their heart function mood and thinking They will answer questions about their symptoms They may choose to have imaging scans and scans of their brain activity

HNK is given through a tube attached to a needle inserted into a vein Participants will receive infusions on this schedule

They will receive 4 infusions over 2 weeks They will stay in the clinical center overnight after each infusion or for the duration of the study

They will receive no drugs for 2 to 3 weeks

They will have 4 more infusions over 2 weeks with overnight stays after each or for the duration of the study

One set of 4 infusions will be the HNK The other set of 4 infusions will be a placebo A placebo looks just like the real drug but contains no medicine Participants will not know when they are getting the HNK or placebo

Detailed Description: Study Description

This is a randomized double-blind placebo-controlled crossover single-site study

This experimental study will assess the efficacy and safety of two weeks of 025 to 20 mgkg 2R6R-hydroxynorketamine HNK an enhancer of synaptic glutamate release The study may be conducted on an inpatient or outpatient basis

Objectives

Primary Objective

The primary objective is to evaluate the ability of 2R6R-HNK an enhancer of synaptic glutamate release to improve overall depressive symptomatology in participants with major depressive disorder MDD The efficacy of a two-week course of 2R6R-HNK will be compared to two weeks of saline placebo in a crossover study Montgomery-Asberg Depression Rating Scale MADRS score will serve as the main outcome measure

Secondary Objectives

1 To evaluate the antidepressant efficacy of 2R6R-HNK at days 0 230 min 1 2 3 4 7 8 10 11 and 12 compared to placebo in a crossover study as assessed by change from baseline on MADRS total scores
2 To determine whether 2R6R-HNK demonstrates superior antidepressant efficacy compared to placebo in a crossover study as assessed by the proportion of participants in remission defined as MADRS total score 10
3 To determine whether antidepressant response to 2R6R-HNK is superior to response to placebo in a crossover study as assessed by the proportion of participants achieving response defined as a 50 reduction from baseline in MADRS total score
4 To evaluate the antisuicidal ideation effects of 2R6R-HNK at days 0 230 min 1 2 3 4 7 8 10 11 and 12 compared to placebo in a crossover study as assessed by change from baseline on item 10 suicidality of the MADRS the Columbia Suicide Severity Rating Scale C-SSRS and the Scale for Suicide Ideation SSI
5 To investigate the effects of 2R6R-HNK on mood anxiety and anhedonia symptoms at days 0 230 min 1 2 3 4 7 8 10 11 and 12 compared to placebo in a crossover study as assessed by change from baseline on the Beck Depression Inventory Second Edition BDI-II Hamilton Depression Rating Scale HDRS Hamilton Anxiety Rating Scale HAM-A Positive and Negative Affect Schedule PANAS Snaith-Hamilton Pleasure Scale SHAPS and the Temporal Experience of Pleasure Scale TEPS as well as change from baseline on various cognitive tasks Auditory Somatosensory and Visual Evoked Fields Task Monetary Incentive Delay MID task Hariri Hamer task and Probabilistic Reward Task PRT
6 To assess the safety and tolerability of a two-week course of 2R6R-HNK compared to placebo in a crossover study by incidence of adverse events AEs and total scores on the Clinician Administered Dissociative States Scale CADSS Young Mania Rating Scale YMRS Brief Psychiatric Rating Scale BPRS vital signs changes in clinical laboratory evaluations and electrocardiograms ECGs
