Sub-dissociative Dose Ketamine in Treatment of Vaso-occlusive Pain Event in Children and Young Adults

September 1, 2026 updated by: Mohsen Saidinejad

Sub-dissociative Dose Ketamine in Treatment of Vaso-occlusive Pain Event in Children and Young Adults: A Randomized Control Trial

The purpose of this research is to see if ketamine is effective and safe in treating children and young adults with sickle cell disease experiencing sickle cell related pain. In this study, we will compare the outcomes (such as pain scores) in persons who receive standard of care pain medicine (an opioid such as morphine) plus a low dose (amount) of ketamine to those who receive only standard of care pain medicine.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Between the ages 5-20 years
  • Diagnosed sickle cell disease. Homozygous (HbSS) or heterozygous (HbSC, HbSBetaThal Plus or Zero) will be included.
  • Presenting with VOE pain, requiring IV pain medication.
  • First dose of analgesic medication is given before patient approached for participation in the study.
  • Primary language is English or Spanish
  • Adult individual or parent/legal guardian is able and willing to provide informed consent. For individuals 7 to 17 years of age, assent must also be provided when cognitively possible.

Exclusion Criteria:

  • Sickle cell trait only
  • Patients whose primary language is other than English or Spanish
  • Pain attributed to causes other than VOE
  • Not requiring IV for pain treatment
  • No analgesic (e.g. opiate) is given before approach for study participation due to any reason, including problem with IV access.
  • Oxygen saturation < 90% on room air
  • History of prior adverse reaction to ketamine
  • History of hypertension - Patients with active/uncontrolled hypertension defined as systolic 140 mmHg over diastolic of 90 mmHg will be excluded from participation in the study. If hypertension is controlled and at the time of enrollment, systolic and diastolic thresholds of 140 mmHg and 90 mmHg respectively are not exceeded, patient may be included in the study
  • History of significant or uncontrolled cardiovascular disease, liver disease, kidney disease, and thyroid disease
  • Patients with evidence of increased intracranial pressure
  • Patients with elevated intraocular pressure
  • Patients with acute mania or history of bipolar disorder with manic episodes, history of hallucinations or paranoia secondary to previously diagnosed psychiatric condition
  • Pregnant or potentially pregnant patients per patient report. All patients of childbearing potential will undergo pregnancy testing prior to enrollment (as part of clinical care), and if positive, will be excluded.
  • Elevated liver enzymes (alkaline phosphatase, ALT, AST, bilirubin) as sign of hepatic disfunction if the laboratory results are available prior to study participation
  • Patients who appear intoxicated on any substance.
  • Patients who are wards of the state or prisoners as defined by DHS
  • Patients who are not deemed to be competent to provide consent or assent.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Total Opioid Medications Required for Analgesia
Time Frame: Up to 3 days
Cumulative morphine-mg equivalent per kilogram (MME/kg) of opioid medication needed to achieve a pain score of ≤ 5
Up to 3 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pain Score
Time Frame: 30 minutes and 60 minutes after administration of placebo vs ketamine infusion
Pain score from 0-10, at 30 and 60 minutes after administration of NS/placebo (control group), versus sub-dissociative ketamine (experimental group)
30 minutes and 60 minutes after administration of placebo vs ketamine infusion
ED Length of Stay
Time Frame: Up to 3 days
To compare ED length of stay between control vs experimental group
Up to 3 days
Rate of Hospitalization
Time Frame: Up to 1 month
To compare rate of hospitalization and length of hospitalization between control and experimental group
Up to 1 month
Quality of Life (Pediatric Quality of Life)
Time Frame: 7-10 days after enrollment in the study and 4-6 weeks after enrollment in the study
To compare overall quality of life between the two groups upon discharge from the ED or the hospital, using the Pediatric Quality of Life (PedsQL) questionnaire. The questionnaire has 43 points and is reverse scored and linearly transformed to a 0-100 scale (0=100, 1=75, 2=50, 3=25, 4=0), so that higher scores indicate better quality of life.
7-10 days after enrollment in the study and 4-6 weeks after enrollment in the study
