- NCT05095857RecruitingPhase 4

Gabapentin and ketamine to treat head and neck cancer pain
This early-phase study tests whether gabapentin and a ketamine nasal spray can help prevent or lessen short-term and long-term pain from locally advanced head and neck cancer. It may help by changing how the nervous system responds to pain during and after radiation and chemoradiation.
Nashville, TennesseeAges 21 years+ - NCT05306899RecruitingPhase 3
IV ketamine for chronic daily headaches
This trial tests whether an IV dose of ketamine can reduce chronic daily headaches and is safe for people with this condition. It may help by lowering headache frequency and severity, but it also has several medicine and health-related safety checks.
Toronto, OntarioAges 18–75 - NCT05327699RecruitingEarly Phase 1
Ketamine study for depression with reduced pleasure
This early-phase study tests whether ketamine can help people with major depression who have trouble feeling pleasure. It also studies how the brain may change in response to stress, to better understand who might respond to treatment.
Atlanta, GeorgiaAges 18–65 - NCT05378555RecruitingPhase 3

This trial tests whether taking ketamine by mouth can help treat “vaso-occlusive” pain episodes that may require hospital admission. If it works, it could offer an easier way to manage severe pain during sickle cell crises.
Boston, MassachusettsAges 12–24 - NCT05450432RecruitingPhase 4
Ketamine maintenance to help prevent suicidal thoughts
This Phase 4 study tests whether ongoing treatment with ketamine or esketamine can reduce suicidal thoughts in people with major depression who are at high risk. Because the study focuses on long-term maintenance, you’d receive treatment over time while being closely monitored for safety and mental health changes.
Boston, MassachusettsAges 18–70 - NCT05737693RecruitingPhase 2

This study tests whether adding ketamine to a structured, one-week psychological therapy program can reduce severe PTSD symptoms. It may help people who have had PTSD for a long time and still feel very affected.
New Haven, ConnecticutAges 21–70 - NCT05786066RecruitingPhase 2
Test whether blocking AMPA changes ketamine’s suicide relief
This study looks at whether an “AMPA receptor blocker” changes how ketamine affects suicidal thoughts in people with depression that hasn’t improved with usual treatments. If you qualify, you may receive ketamine and the study medicine, while continuing your regular mental health care.
West Haven, ConnecticutAges 21–65 - NCT05821972RecruitingPhase 4
Breathing-mist medicines for cleft palate surgery pain control
This trial tests whether a breathing mist of two medicines (dexmedetomidine plus ketamine) works better than dexmedetomidine alone during cleft palate repair surgery. It may help improve comfort and safety around anesthesia for eligible patients.
AsyutAges 1–4 - NCT05915013RecruitingPhase 1
Brain-targeting study of ketamine response in treatment-resistant depression
This early-stage study looks at how parts of brain cells respond to ketamine in people with depression who have not improved with usual antidepressants. It may help researchers find why ketamine works for some people and not others, and who might benefit.
New Haven, ConnecticutAges 18–60 - NCT05934669RecruitingPhase 4
Numbing medicines compared for small stitches in young children
This trial tests three medicines given through the nose to keep children comfortable during minor procedures in the emergency department, specifically for closing small cuts with stitches. It may help find which nasal medicine works best and is safest for quick, minimal procedures.
Oklahoma City, OklahomaAges 1–5 - NCT05940324RecruitingPhase 2
Ketamine study for OCD after prior treatment failed
This Phase 2 study tests how ketamine may work quickly in people with obsessive-compulsive disorder (OCD), especially after at least one standard treatment didn’t help. If you join, you’ll need to follow study procedures like fasting before the experimental visit and not enrolling in other medication trials during the study.
Stanford, CaliforniaAges 18–65 - NCT06038409Recruiting
Ketamine therapy for chronic conditions
This trial tests if ketamine can help people with long-term health issues. It aims to find new treatments for chronic conditions that haven't responded well to other therapies.
Helena, MontanaAges 18 years+ - NCT06062628RecruitingEarly Phase 1
Ketamine for severe traumatic brain injury
This study tests whether a low dose of ketamine can help people with severe traumatic brain injury by reducing brain pressure and improving oxygen levels. If you have a brain monitor in place and meet safety criteria, you may be able to join.
Dallas, TexasAges 18 years+ - NCT06070766Recruiting
At-home ketamine study for chronic conditions
This trial tests a ketamine protocol you can use at home. It may help if you have a long-term health condition.

TromsøAges 18–65 - NCT06125054RecruitingPhase 2
Ketamine and brain training for cocaine addiction
This trial tests whether a combination of ketamine (a medicine that may help the brain change) and neurofeedback training (a brain-exercise technique) can help people with cocaine addiction. The goal is to see if these treatments can improve brain flexibility and reduce cravings.
Zurich, Canton of ZurichAges 18–55 - NCT06140927RecruitingPhase 3
Ketamine's effect on spinal monitoring during back surgery
