Adjuvant Low-dose Ketamine in Pediatric Sickle Cell Vaso-occlusive Crisis
A Phase 2 study testing Ketamine in people with Sickle Cell Disease and Vaso-Occlusive Crisis, run by UCSF Benioff Children's Hospital Oakland at 1 site in United States.
Trial summary
Acute vaso-occlusive episodes (VOEs) in sickle cell disease (SCD) are primarily managed with opioids. Tolerance and hyperalgesia to opioids develops due to N-methyl-D-aspartate (NMDA)-receptor mediated activation of the nociceptive system, and as a receptor antagonist, ketamine mitigates this.

About this study
Official title: Adjuvant Low-dose Ketamine in Pediatric Sickle Cell Vaso-occlusive Crisis (AKTSS)
Acute vaso-occlusive episodes (VOEs) in sickle cell disease (SCD) are primarily managed with opioids. Tolerance and hyperalgesia to opioids develops due to N-methyl-D-aspartate (NMDA)-receptor mediated activation of the nociceptive system, and as a receptor antagonist, ketamine mitigates this. Intravenous (IV) ketamine has demonstrated efficacy in reducing post-operative, chronic, and cancer-related pain in pediatrics, as well as in reducing time to pain control in the emergency department (ED) in adults. Limited studies suggest efficacy in adult opioid-refractory SCD patients. This study is investigating the safety and tolerability of adjuvant low-dose IV ketamine bolus for pediatric SCD VOE in the ED, as well as its efficacy in improving pain control and reducing hospitalization.
Read the detailed description
In this cohort study, all consenting pediatric sickle-cell patients between 10 and 25 years old who were cared for at UCSF Benioff Children's Hospital Oakland (UCSFBCHO) presenting to the emergency department for VOC were enrolled in the study. Patients were compared to themselves in a time series, pre and post exposure to the study intervention (low-dose ketamine bolus at 0.2 mg/kg x 1 prior to second dose of IV opiate). The pediatric FACES pain scale was used to measure pain scales at pre-designated time points in the ED per standard nursing protocol (FACES for younger kids, visual analog scale in adolescents/young adults). Opiate usage was summed in the ED, converted to mg/kg/hour of morphine equivalents (since different opioids agents were given to different patients based on individual historical efficacy, and since length of stay in the emergency room could affect total morphine equivalents received), and compared between the pre and post-intervention groups. In addition, length of stay, time to 50% pain control, presentation and discharge pain scores, and likelihood of discharge from the ED were compared. Data was be collected via chart review in the UCSFBCHO system by study investigators. Pre-intervention data from the past three patient encounters (e.g., the mean of the mg/kg/hour of morphine equivalents used in the last three patient encounters prior to receipt of ketamine) was compared to the post intervention data. In addition, a survey, which is attached, was given to patients/families at the time of the drug administration to attempt to discern if patients subjectively experienced improvement in their pain and if they experienced any negative side effects due to the drug administration. Monitoring for adverse events was recorded for each patient encounter.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
KetamineDrug
Also called Ketalar
The intervention is IV low-dose bolus ketamine as an adjuvant to standard therapy (IV opiates and NSAIDs).
| Study group | Role | What they receive |
|---|---|---|
| Intervention | Active comparator | Prior to the second dose of IV opiates, the experiment was to give patients a single IV bolus of ketamine at the dose of 0.2 mg/kg. Pain scores were collected using the FACES scale currently in place. In consenting patients, chart review was performed with the following data collected: mg/kg/hour of morphine equivalents, pain scores on admission, during the encounter, and at discharge, the time to 50% pain reduction, and whether or not the patient was discharged.
In addition, a survey, which is attached, was given to patients/families at the time of drug administration to determine if they experienced a subjective improvement in their pain and if they suffered any undue side effects due to drug administration. Receives: Drug: Ketamine |
| Historical Control | No intervention | Patient data from at least one but up three patient encounters within the prior year were compared to their visit in which they were given adjuvant ketamine, using the outcome measures in the "Intervention" arm. Since this a historical control study, patients acted as their own controls in the above manner. Patients were allowed to re-enroll 4 weeks after presentation, which is typically considered a separate vaso-occlusive episode in the literature. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Treatment-Emergent Adverse Events [Safety and Tolerability]
The number of serious and minor adverse events was measured via patient-completed survey as well as by nurse and medical providers on presentation to the emergency department (ED). Serious adverse events are defined as cardiorespiratory events requiring intervention. Minor adverse events are defined as nausea/vomiting, emergence reaction (dysphoria; hallucinations; frightening dreams), and a sense of de-realization or "dreamy" sensation. Both study providers and patients themselves, via a survey that the parent and/or patient (based on age) fills out post receipt of ketamine, reported serious and minor adverse events.
Measured: 18 months
Secondary outcomes (7)
Effect of Low-dose Ketamine (LDK) on Opioid Usage in the ED
Opioid usage for at least one but up to three prior patient visits in the last one year for each patient enrolled in the study was summarized, expressed as morphine equivalents in mg/kg/h, to account for different types of opioids used per patient preference, and then this was compared to the intervention group that received LDK. Percent change in opioid usage (expressed as morphine equivalents in mg/kg/h) is reported).
Measured: Up to one year prior and after LDK administration on day 1 of the study in the ED
Effect of Low-dose Ketamine on Pain Scores on Presentation to the ED
Patient pain scores at presentation for the enrolled encounters and for at least one but up to three visits prior to receipt of ketamine in the last one year, were assessed. At least one but up to three prior visits were averaged and compared to the intervention visit. Pain was assessed using the faces pain scale which consists of a series of line diagrams of faces with expressions of increasing distress. The score ranges from 0 (no pain) to 10 (the worst pain).
Measured: Up to one year prior and on presentation to the ED after LDK administration
Effect of Low-dose Ketamine on Discharge Rates From the ED
Percent discharge from the ED for intervention group and for at least one but up to three visits prior to receipt of ketamine in the last one year, were assessed. Participants were assigned a "0" if discharged or "1" if not discharged.
Measured: Up to one year prior to receipt of ketamine for the historical control arm/group and up to 18 months for the intervention arm/group
Subjective Effect of Low Dose Ketamine on Pain Relief Assessed Via a Patient Survey
After receipt of LDK, patients and/or their parents, based on age, filled out a survey based on a Likert scale regarding their agreement (Strongly Disagree to Strongly Agree) with the following statements: Achieved faster pain relief with LDK, Achieved more complete pain relief with LDK, and Desire to receive LDK in a future vaso-occlusive crisis. There is also an area where patients could provide general comments regarding their experience in receiving LDK.
Count of Participants who agree or strongly agree for each question are reported.
Measured: after LDK administration on day 1 of the study in the ED
Effect of Low-dose Ketamine on Patient Pain Scores on Discharge From the ED/Admission to the Hospital
Patient pain scores at time of discharge from the ED/admission to the hospital for at least one but up to three visits prior to receipt of ketamine in the last one year, were assessed. At least one but up to three prior visits were averaged and compared to the intervention visit. Pain scores post receipt of ketamine are presented for the intervention group. Pain was assessed using the faces pain scale which consists of a series of line diagrams of faces with expressions of increasing distress. The score ranges from 0 (no pain) to 10 (the worst pain).
Measured: At time of discharge from the ED/admission to the hospital (up to one year prior and after LDK administration)
Effect of Low-dose Ketamine on Percent Difference of Length of Stay (LOS) in the ED
Length of stay (LOS) in minutes in the ED for at least one but up to three visits prior to receipt of ketamine in the last one year, were assessed.
Measured: Up to one year prior to and after LDK administration on day 1 of the study in the ED
Effect of Low-dose Ketamine on Time to 50% Pain Reduction
Time to 50% pain reduction (pain reported 50% less than baseline) in minutes for at least one but up to three visits prior to receipt of ketamine in the last one year, were assessed as historical controls. Pain was assessed using the faces pain scale which consists of a series of line diagrams of faces with expressions of increasing distress. The score ranges from 0 (no pain) to 10 (the worst pain).
Measured: Up to one year prior to and after LDK administration on day 1 of the study in the ED

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Acute vaso-occlusive episodes (VOEs) in sickle cell disease (SCD) are primarily managed with opioids. Tolerance and hyperalgesia to opioids develops due to N-methyl-D-aspartate (NMDA)-receptor mediated activation of the nociceptive system, and as a receptor antagonist, ketamine mitigates this. Intravenous (IV) ketamine has demonstrated efficacy in reducing post-operative, chronic, and cancer-related pain in pediatrics, as well as in reducing time to pain control in the emergency department (ED) in adults. Limited studies suggest efficacy in adult opioid-refractory SCD patients. This study is investigating the safety and tolerability of adjuvant low-dose IV ketamine bolus for pediatric SCD VOE in the ED, as well as its efficacy in improving pain control and reducing hospitalization.

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 20 Apr 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Treatment-Emergent Adverse Events [Safety and Tolerability] (time frame: 18 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03296345, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2021.
