Ketamine Treatment Options in New York

Ketamine is a non-competitive N-methyl-D-aspartate (NMDA)/glutamate receptor complex antagonist that decreases pain by diminishing central sensitization, hyperalgesia, and "wind-up" phenomenon at the level of the spinal cord (dorsal ganglion) and central nervous system (1). Ketamine administration in sub-dissociative doses (SDK) of 0.1-0.3 mg/kg in pre-hospital settings and in the ED results in effective pain relief in patients with acute traumatic and non-traumatic pain, chronic non-cancer and cancer pain, and in patients with opioid-tolerant pain by virtue of providing anti-hyperalgesia, anti-allodynia, and anti-tolerance (2-4). Two commonly utilized routes of SDK administration in the ED include an intravenous route (intravenous push dose or short infusion) and intranasal route. In the situation when intravenous access is not readily available or unobtainable, and intranasal route is not feasible, another non-invasive route of ketamine administration such as inhalation via Breath-Actuated Nebulizer (BAN) is coming into the play. The BAN allows a controlled patient-initiated delivery of analgesics in titratable fashion. Nebulized administration of ketamine has been studied in the areas of acute postoperative pain management (post-intubational sore throat), in anesthesia (pre-medication for general anesthesia,) and in managing cancer pain, and status asthmaticus therapy. However, our research team has published a case series of 5 patients receiving nebulized ketamine for a variety of acute painful conditions and has recently completed a randomized double-blind trial of 120 adult patients that evaluated analgesic efficacy and safety of nebulized ketamine at three different dosing regimens for acute pain in the ED. Currently, we are conducting two additional studies evaluating the role of nebulized ketamine in pediatric ED and pre-hospital arena. In this study the investigators hypothesize that intravenous sub-dissociative-dose ketamine of 0.3 mg/kg will provide better analgesia at 30 min post-medication administration in comparison to nebulized ketamine administered at 0.75 mg/kg. The primary outcome of this trial is the comparative reduction in participant's pain scores at 30 minutes post medication administration. Read Less

Ketamine-Assisted Psychotherapy (KAP) is a relatively new approach for the treatment of mental health issues, which involves the combination of ketamine, a dissociative anaesthetic with psychedelic properties, and psychotherapy to promote emotional wellbeing. In this study, we investigated the effectiveness of KAP in adult patients coping with mental health. We predicted that clients would experience lasting reductions in psychological distress over time, such as depression, anxiety, and post traumatic stress, that would be detectable up to 6 months after treatment. The results of this study may provide evidence of sustained real-world effects of Ketamine-Assisted Psychotherapy, of interest to patients, clinicians, researchers, and policymakers. Read Less

The incidence of opioid use disorders (OUDs) has increased to near-epidemic proportions. While maintenance with long-acting opioids such as methadone or buprenorphine represents an effective treatment strategy, it may be unacceptable to many individuals. As a result, long-acting injectable naltrexone (XR-NTX), an antagonist medication that blocks the effects of opioids for at least 4 weeks, is now indicated for relapse prevention following detoxification. This randomized, controlled trial aims to test the efficacy of a glutamate modulator at facilitating a rapid non-opioid based naltrexone induction. Read Less

Patients with head and neck cancer generally receive a standard of care of 7 weeks of daily radiation therapy given alongside an aggressive chemotherapy drug called cisplatin. While rates of cure are often strong for patients who are able to complete treatment without any unscheduled breaks, the rates of high grade toxicity associated with this treatment are high even with the use of the most modern techniques of treatment. Pain, swallowing dysfunction, loss of taste sensation, and ulceration of the mouth and throat are ubiquitous and often contribute to a nutritional breakdown requiring feeding tube placement. Unfortunately, even with aggressive use of opioids and other conventional palliation methods, breakthrough pain and other toxicities are very common. In addition to the quality of life burdens of these side effects, patients who are unable to complete treatment on schedule have worse control of their cancer and worse overall survival. Clearly, there is a clinical need for better management of these toxicities. The investigators hypothesize that ketamine mouthwash may effectively reduce both pain and the need for opioid drugs in this patient population. There is a large body of literature supporting the use of ketamine for pain control in diseases other than cancer, and a smaller but growing body of literature showing the effectiveness of ketamine for control of cancer-associated pain. Additionally, by providing ketamine in mouthwash form, the evidence shows that one can avoid the side effects associated with giving ketamine throughout the body, and in fact no significant side effects have been reported so far with this treatment. In this study, the investigators will provide ketamine mouthwash to patients undergoing the standard treatment for this disease over a two week period, and measure their response in terms of both pain and need for opioids, as well as other measurements of quality of life. The investigators will also measure unscheduled interruptions in treatment. In years to come, the data from this study may show an impact on cancer control and survival. Read Less

Headaches affect over 50% of patients annually, with close to 4% of ED visits for headache. Most headaches managed in the ED are benign, with 90% of these headaches classified as tension, migraine, or cluster. At present, the satisfaction with ED treatment of headache is low, and despite the multitude of available medications, the evidence- based treatment options are often quite limited. There are over twenty different types of medications available to the ED clinicians for managing headache, many with different routes of administration (parenteral, intranasal, subcutaneous, and oral). Many of these medications are provided in so-called "headache cocktail", which varies based on the physician, institution, and patient preferences. Read Less

Depression is the leading cause of disability globally (1, 2). One-third to one-half of patients suffering from major depressive disorder (MDD) do not achieve remission even after multiple antidepressant trials (3). Ketamine is a commonly-used FDA-approved anesthetic medication that at subanesthetic doses leads to rapid antidepressant and anti-suicidal ideation effects in hours, rather than weeks, following administration. Despite these promising findings, a key limitation of ketamine treatment is that it only yields an antidepressant response in approximately 50% of those treated. The goal of this project is to A) elucidate ketamine's mechanism of action and B) identify biomarkers predicting treatment outcome to ketamine which could be used to match patients to treatment based on the likelihood of effectiveness at the individual level. Data from animal models suggests that ketamine acts by enhancing the connections between neurons through a process known as synaptic plasticity (4-7), and that these biological changes are responsible for the sustained behavioral effects of ketamine (8). A newly available tool allows us to image the density of these synaptic connections in the living brain using PET (positron emission tomography) imaging with a radiotracer called \[11C\]UCB-J, which is a marker of synaptic density. We propose to directly quantify synaptic density in depressed patients before and after a course of ketamine, to examine changes in density following treatment. In exploratory analyses, we will examine synaptic density as a mediator of the sustained antidepressant effects of ketamine and as a predictor of treatment outcome. To study these questions, we will quantify synaptic density using PET imaging before and after a course of 4 sequential intravenous infusions of ketamine administered over a two week period. Study participation involves an inpatient stay of approximately three weeks at the New York State Psychiatric Institute at no cost. Read Less

The proposed project tests the efficacy of glutamate modulators in non-depressed individuals with alcohol use disorder (AUD); the primary hypothesis is that the glutamate modulator being tested reduces heavy drinking days compared to the active control. It also aims to investigate, using a 2 by 2 factorial (2x2) design, the hypothesis that the effects of the glutamate modulator are enhanced when combined with behavioral treatment. Read Less

The purpose of the study is to evaluate the efficacy, safety, and tolerability of SLS-002 (intranasal racemic ketamine) in addition to standard of care on symptoms of Major Depressive Disorder (MDD) and suicidality, in participants who are assessed to be at imminent risk for suicide, as measured by the change from baseline on the Montgomery-Asberg Depression Rating Scale (MADRS) total score at 24 hours post first dose.

This is a Phase 2A, single dose, open-label study to evaluate the safety, tolerability, and efficacy of a low-dose, 40-minute infusion into the veins (intravenous infusion or "IV") of ketamine in children with ADNP syndrome (Activity-Dependent Neuroprotective Protein). The study team will enroll 10 participants, ages 5 to 12, at Mount Sinai. The study participation is expected to last 4 weeks and will include 5 scheduled clinic visits in order to complete safety monitoring, clinical assessments, and biomarker collection. At the conclusion of this study, the study team expects to demonstrate the safety and tolerability of low-dose ketamine in children with ADNP syndrome. Additionally, the study team anticipates identifying meaningful signals of efficacy in clinical outcome measures using RNA and DNA sequencing to analyze ADNP protein expression and DNA methylation profiles, a natural process by which methyl groups are added to the DNA to change its activity, in order to assess sensitivity to change with low-dose ketamine treatment and inform future phase 3 studies. Ketamine is not currently approved by the Food and Drug Administration to treat this syndrome, but it is approved for use in children in other situations, for example in anesthesia. Read Less
