Understanding profiles of patients with treatment-resistant depression by stringency of health plan prior authorization criteria for approval of esketamine nasal spray. Curr Med Res Opin 2024; 40:1615-1623. [PMID: 39034772 DOI: 10.1080/03007995.2024.2380743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Revised: 07/10/2024] [Accepted: 07/12/2024] [Indexed: 07/23/2024]
Abstract
OBJECTIVES In the United States (US), prescription drug coverage is subject to prior authorization (PA) criteria, which may vary between health plans and may exceed drug label requirements. This study aimed to characterize profiles and treatment history of patients with treatment-resistant depression (TRD) who initiated esketamine nasal spray, by stringency of their health plans' PA criteria relative to the esketamine label. METHODS Adults with evidence of TRD (≥2 antidepressant courses of adequate dose and duration) prior to initiating esketamine were identified using US insurance claims data (03/2016-02/2022). Based on health plan PA criteria for esketamine obtained from Managed Markets Insight & Technology data (05/2020-02/2022), patients were grouped into stringent (PA criteria exceeds label) and non-stringent (PA criteria less stringent or equal to label) cohorts. Patient treatment history before esketamine initiation was compared using Wilcoxon rank sum and Fisher's exact tests. RESULTS The stringent cohort included 168 patients (mean age: 45 years, 63% female) and the non-stringent cohort included 400 patients (mean age: 45 years, 70% female). During the ongoing major depressive episode before esketamine initiation, the stringent versus non-stringent cohort completed 3.9 versus 3.8 antidepressant treatment courses, on average (p = 0.217); 94.6% versus 96.8% used augmentation therapy (p = 0.240), including 59.3% versus 58.1% with an antipsychotic (p = 0.844), respectively. CONCLUSIONS Regardless of health plan stringency, on average, patients exceeded US label-mandated number of antidepressant trials before esketamine initiation, which questions the need for health insurance plans PA criteria above label.

Treatment Patterns, Acute Healthcare Resource Use, and Costs of Patients with Treatment-Resistant Depression Completing Induction Phase of Esketamine in the United States. Drugs Real World Outcomes 2024; 11:209-219.

Abstract
BACKGROUND This study aimed to understand treatment patterns, acute healthcare use, and cost patterns among adults with treatment-resistant depression (TRD) who completed induction treatment with esketamine nasal spray in the United States (US). Per label, induction is defined as administration twice a week for 4 weeks, after which maintenance is started on a weekly basis for 4 weeks, and thereafter, patients are treated weekly or bimonthly. METHODS Adults with one or more esketamine claim (index date) on or after March 5, 2019 were selected from Optum's de-identified Clinformatics® Data Mart Database (January 2016-June 2022). Before the index date, patients had evidence of TRD and ≥ 12 months of continuous insurance eligibility (baseline period). Patients with eight or more esketamine treatment sessions were included in the main cohort. A subgroup included patients with one or more baseline mental health (MH)-related inpatient (IP) admission or emergency department (ED) visit (i.e., prior acute healthcare users). Treatment patterns were described during the follow-up period (index date until earliest of end of insurance eligibility or data); acute healthcare (i.e., IP and ED) resource use and costs (2021 US dollars) were reported during the baseline and follow-up periods. RESULTS Of the 322 patients in the main cohort, 111 comprised the subgroup of prior acute healthcare users. During the follow-up period, mean time from index date to eighth esketamine session was 73.2 days in the main cohort and 78.8 days in the subgroup (per label, 28 days). Further, 75.2% of the main cohort and 73.9% of the subgroup completed four or more esketamine maintenance sessions following induction. In the main cohort, mean all-cause acute healthcare costs per patient per month (PPPM) decreased from baseline ($837) to follow-up ($770). Similar reductions were observed for mean MH-related acute healthcare costs PPPM (baseline $648, follow-up $577). In the subgroup, mean all-cause acute healthcare costs PPPM also decreased (baseline $2323, follow-up $1423), driven by mean MH-related acute healthcare costs PPPM (baseline $1880, follow-up $1139). Mean all-cause acute healthcare use per ten patients per month remained largely stable from baseline to follow-up in the main cohort (IP days: baseline 2.24, follow-up 2.13; ED visits: baseline 1.33, follow-up 1.45) and decreased in the subgroup (IP days: baseline 6.38, follow-up 4.56; ED visits: baseline 2.58, follow-up 2.41). Trends in mean MH-related acute healthcare use were similar. CONCLUSION Patients generally required more time than label recommendation to complete esketamine induction treatment, and most went on to have 12 or more esketamine sessions. Completion of induction treatment correlated with reductions in mean all-cause and MH-related acute healthcare costs. Larger reductions were seen in the subgroup of prior acute healthcare users.

Abstract
In this paper, the case study of ketamine as a new treatment for severe depression is used to outline the challenges of repurposing established medicines and we suggest potential solutions. The antidepressant effects of generic racemic ketamine were identified over 20 years ago, but there were insufficient incentives for commercial entities to pursue its registration, or support for non-commercial entities to fill this gap. As a result, the evaluation of generic ketamine was delayed, piecemeal, uncoordinated, and insufficient to gain approval. Meanwhile, substantial commercial investment enabled the widespread registration of a patented, intranasal s-enantiomeric ketamine formulation (Spravato®) for depression. However, Spravato is priced at $600-$900/dose compared to ~$5/dose for generic ketamine, and the ~AUD$100 million annual government investment requested in Australia (to cover drug costs alone) has been rejected twice, leaving this treatment largely inaccessible for Australian patients 2 years after Therapeutic Goods Administration approval. Moreover, emerging evidence indicates that generic racemic ketamine is at least as effective as Spravato, but no comparative trials were required for regulatory approval and have not been conducted. Without action, this story will repeat regularly in the next decade with a new wave of psychedelic-assisted psychotherapy treatments, for which the original off-patent molecules could be available at low-cost and reduce the overall cost of treatment. Several systemic reforms are required to ensure that affordable, effective options become accessible; these include commercial incentives, public and public-private funding schemes, reduced regulatory barriers and more coordinated international public funding schemes to support translational research.

Treatment-Resistant Depression in America Latina study: one-year follow-up of treatment resistant depression patients under standard of care reveals insights on quality of life, disability, work impairment, and depressive symptoms. Front Psychiatry 2023; 14:1221746. [PMID: 37965358 PMCID: PMC10641694 DOI: 10.3389/fpsyt.2023.1221746] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Accepted: 10/03/2023] [Indexed: 11/16/2023] Open
Abstract
Introduction Depressive Disorders are on the rise worldwide. This is also the case in Latin America (LatAm). Treatment-Resistant Depressive Disorder (TRD) poses additional burden to patients with depression. Impacts quality of life (QoL) and other dimensions, and standard of care (SOC) is insufficient to achieve the desired clinical outcomes. Evidence from LatAm is, however, lacking. The present study was devised as a 1-year follow-up of the SOC in TRD patients in LatAm to explore the burden of TRD. Methods This was an observational, multinational, longitudinal study. Patients with clinical diagnosis of TRD in LatAm were included in a 1-year follow-up with SOC. Beyond the Sociodemographic characterization, outcome measures were QoL (EQ-5D-5L), disability (Sheehan Disability Scale - SDS), work productivity (Work Productivity and Activity Incapacity Questionnaire: depression - WPAI:D) and depression severity (Patient Health Questionnaire-PHQ9). Patients were assessed every 3-months and comparison was performed based on change from baseline to each visit and end of study (EOS - 12 months). Results Patients averaged 48 (± 13.12) years, mostly female (80.9%) and married/consensual union (42.5%) or single patients (34.4%). Despite the SOC treatment, three-quarters of the patients remained symptomatic at EOS, regardless of the significant longitudinal decrease (p ≤ 0.001). Similar trends were found for disability (p ≤ 0.001) -82.2% of the patients reporting work/school disruption at EOS-, percentage of work (34%) and activity impairment (40%) at EOS (p ≤ 0.001) and only 29.2% of patients with depressive severity "none" at EOS (p ≤ 0.001). The results portray the need to improve clinical outcomes in this complex and burdensome disease in LatAm. Discussion Here we show that the burden of TRD remains significant in essential dimensions of everyday life at EOS underlining the need for better therapeutic solutions. The improvements in most patients do not provide the desired outcome of return to the state before the condition. Further research should focus on identifying which treatments provide better outcomes in a real-world context.

Abstract
BACKGROUND Ideal sedation and analgesia strategies for fiberoptic bronchoscopy have not been found. At present, propofol based sedation strategy still has some defects, such as respiratory depression and blood pressure drop. It is difficult to meet the requirements of safety and effectiveness at the same time. The aim of this study was to compare the clinical efficacy of propofol/remifentanil with propofol/esketamine for patient sedation during fiberoptic bronchoscopy. METHOD Patients undergoing fiberoptic bronchoscopy were randomly assigned to propofol/ remifentanil (PR group; n = 42) or propofol/esketamine (PK group; n = 42) for sedation and analgesia. The primary outcome was the rate of transient hypoxia (oxygen saturation (SpO2) < 95%). The secondary outcomes are the intraoperative hemodynamics, including the changes in blood pressure, heart rate, the incidence of adverse reactions, the total amount of propofol usage were recorded, and the satisfaction level of patients and bronchoscopists. RESULTS After sedation, the arterial pressure and heart rate of patients in the PK group were stable without significant decrease. Decreases in diastolic blood pressure, mean arterial pressure, and heart rate were observed in patients in the PR group (P < 0.05), although it was not of clinical relevance. The dosage of propofol in the PR group was significantly higher than that in the PK group (144 ± 38 mg vs. 125 ± 35 mg, P = 0.012). Patients in the PR group showed more transient hypoxia (SpO2 < 95%) during surgery (7 vs. 0, 0% versus 16.6%, P = 0.018), more intraoperative choking (28 vs. 7, P < 0.01), postoperative vomiting (22 vs. 13, P = 0.076) and vertigo (15 vs. 13, P = 0.003). Bronchoscopists in the PK group showed more satisfaction. CONCLUSION Compared with remifentanil, the combination of esketamine with propofol in fiberoptic bronchoscopy leaded to more stable intraoperative hemodynamics, lower dosage of propofol, lower transient hypoxia rate, fewer incidence of adverse events, and greater bronchoscopists satisfaction.

Abstract
INTRODUCTION While the majority of current research and development surrounds depression, demoralization, and substance use disorders, there are numerous reports of psychedelics having beneficial effects in other branches of medicine, including for headache disorders and chronic pain. AREAS COVERED This perspective reviews conventional forms of treatment for headache and other chronic pain disorders and describes historical, recent, and ongoing investigations of the therapeutic effects of psychedelics in these disorders. The first two clinical trials of psilocybin in headache disorders and recent case reports of psilocybin mushroom self-administration in chronic pain patients are described. This perspective highlights several factors related to the application of psychedelics in chronic pain disorders, comparing this with the standard psychedelic-assisted psychotherapy model of treatment. EXPERT OPINION When faced with a more constricted view of psychedelic medicine that features larger doses, underscores subjective effects in the mediation of therapeutic outcomes, and requires adjunctive psychotherapy to ensure safety and efficacy, the application of psychedelics in headache and chronic pain disorders may face challenges. It will be important to allow for flexibility and adaptation in protocols to evaluate different treatment paradigms, mechanisms of action, and the range of pharmacologic and extra-pharmacologic factors that affect psychedelic treatment outcomes.

Abstract
Aim: There is limited real-world evidence for patients with treatment-resistant depression (TRD) receiving esketamine nasal spray. Methods: This retrospective cohort study used data collected from a psychiatric clinic's EHR system. Results: A total of 171 TRD patients received esketamine July 2019-June 2021. This predominantly female, white population had several mental health comorbidities and high exposure to psychiatric medications. We observed significant reductions (p < 0.001) in average PHQ-9 and GAD-7 scores from baseline (PHQ-9: mean: 16.7; SD: 5.8; GAD-7: mean: 12.0; SD: 5.8) to last available treatment (PHQ-9: mean: 12.0; SD: 6.4; GAD-7: mean: 8.7; SD: 5.6). There were no reports of serious adverse events. Conclusion: This study found a significant disease burden for patients with TRD. Esketamine appears to be well tolerated and effective in improving depression and anxiety.

Abstract
Currently, ketamine is used in treating multiple pain, mental health, and substance abuse disorders due to rapid-acting analgesic and antidepressant effects. Its limited short-term durability has motivated research into the potential synergistic actions between ketamine and psychotherapy to sustain benefits. This systematic review on ketamine-assisted psychotherapy (KAP) summarizes existing evidence regarding present-day practices. Through rigorous review, seventeen articles that included 603 participants were identified. From available KAP publications, it is apparent that combined treatments can, in specific circumstances, initiate and prolong clinically significant reductions in pain, anxiety, and depressive symptoms, while encouraging rapport and treatment engagement, and promoting abstinence in patients addicted to other substances. Despite much variance in how KAP is applied (route of ketamine administration, ketamine dosage/frequency, psychotherapy modality, overall treatment length), these findings suggest psychotherapy, provided before, during, and following ketamine sessions, can maximize and prolong benefits. Additional large-scale randomized control trials are warranted to understand better the mutually influential relationships between psychotherapy and ketamine in optimizing responsiveness and sustaining long-term benefits in patients with chronic pain. Such investigations will assist in developing standardized practices and maintenance programs.

Abstract
BACKGROUND Classic psychedelics show promise in the treatment of mental health conditions; however, more scalable intervention protocols are needed to maximize access to these novel therapeutics. In this proof-of-concept study, perceptions of safety, subjective effects, and beliefs about the clinical utility of lysergic acid diethylamide (LSD) were evaluated among healthy participants (N = 31) administered 50 to 100 µg LSD in a treatment paradigm conceptualized as more scalable than traditional approaches to administering classic psychedelics. METHODS Semi-structured interviews assessed participants' expectations, experience, and thoughts on the safety and efficacy of the study design. These interviews were transcribed for thematic analysis relating to perceptions of safety, subjective effects, and beliefs about the clinical utility of LSD. RESULTS Most participants felt safe throughout the study, with a minority reporting concerns related to having a challenging experience that diminished over time. Participants attributed their feelings of safety to the study structure and support of their attendants, which allowed them to "let go" and immerse themselves in the experience without pre-occupation. Furthermore, participants reported transcendent, mystical-type experiences characteristic of classic psychedelics, with almost half highlighting the prominent role played by music during the acute period of drug action. Finally, participants endorsed support for the clinical utility of LSD in controlled environments, expressing the belief that LSD is safe and has the potential to help others. CONCLUSION Findings provide preliminary support for the feasibility of this scalable interventional paradigm and set the stage for future critical research with clinical populations.

Patterns and Predictors of Off-Label Drug Prescribing in Psychiatric Practice: A Qualitative Study. PHARMACY 2021; 9:pharmacy9040203.

Abstract
Off-label drug prescribing (OLDP) must be based on strong scientific evidence to make sure that patients get the optimum therapeutic outcomes. Adherence to the prerequisites is determined by the physicians’ attitude and knowledge. In this context, the present study was conducted with the goal of investigating psychiatrists’ perceptions of the use of OLDP in their clinical practice. A total of 14 psychiatrists were interviewed using a semi-structured interview guide. Thematic content analysis was performed. Data saturation was achieved at the 12th interview. Six major themes and fifteen subthemes emerged from qualitative interviews. Among the major themes were knowledge and concepts about the off-label drugs, attitude and current practice of prescribing off-label drugs, and rationale of prescribing and suggestions for reducing the use of off-label drugs. Almost all of the respondents interviewed provided detailed comments concerning the OLDP concept, depicted an optimistic approach and deemed that OLDP is quite common in psychiatry. Off-label usage of benzodiazepines such as clonazepam, diazepam and lorazepam in mania, depression, and obsessive–compulsive disorder were commonly reported. It was observed that the majority of the respondents did not inform the patients before prescribing off-label drugs. The present findings revealed that respondents had awareness; however, they depicted diverse attitudes towards prescribing off-label drugs. Further education and sensitization in regions with impoverished knowledge would certainly assist in preventing the risks associated with the use of OLDP.

Abstract
INTRODUCTION Ketamine has emerged as a rapid-acting antidepressant. While ongoing treatment can prevent relapse, concerns exist regarding long-term exposure. OBJECTIVE We conducted a randomized trial to examine the feasibility and efficacy of cognitive behavioral therapy (CBT) following intravenous ketamine in treatment-resistant depression (TRD). METHODS Subjects with TRD were recruited and treated with 6 intravenous infusions of ketamine over 3 weeks. Subjects who experienced a clinical response (≥50% improvement in depression severity) were then randomized to receiving CBT or treatment as usual (TAU) for an additional 14 weeks, using a sequential treatment model. RESULTS Of the 42 patients who signed consent, 28 patients achieved a response and were randomized to CBT or TAU. When measured using the Montgomery-Asberg Depression Rating Scale (primary outcome measure), the effect size at the end of the study was moderate (Cohen d = 0.65; 95% CI -0.55 to 1.82), though the group-by-time interaction effect was not significant. There was a significant group-by-time interaction as measured by the Quick Inventory of Depressive Symptomatology (F = 4.58; p = 0.033), favoring a greater sustained improvement in the CBT group. This corresponded to a moderate-to-large effect size of the Cohen d = 0.71 (95% CI -0.30 to 1.70) at the end of the study (14 weeks following the last ketamine infusion). In a subset of patients (N = 20) who underwent cognitive testing using the emotional N-back assessments before and after ketamine, ketamine responders showed improvement in the accuracy of emotional N-back (t[8] = 2.33; p < 0.05) whereas nonresponders did not (t[10] <1; p ns). CONCLUSIONS This proof-of-concept study provides preliminary data indicating that CBT may sustain the antidepressant effects of ketamine in TRD. Further study and optimization of this treatment approach in well-powered clinical trials is recommended.

Abstract
OBJECTIVE This study aimed to estimate the cost-effectiveness of esketamine, a novel intranasally dosed antidepressant, for patients in the United States with treatment-resistant depression. METHODS A decision-analytic model parameterized with efficacy data from phase 3 randomized trials of esketamine was used to simulate the effects of treatment with esketamine versus oral antidepressants over a 5-year horizon, from both societal and health care sector perspectives. Outcomes included remission and response of depression, quality-adjusted life-years (QALYs), costs, and incremental cost-effectiveness ratios (ICERs) for esketamine. Value-based prices were calculated, defined as the per-dose price at which esketamine would become cost-effective given cost-effectiveness thresholds of $50,000/QALY, $100,000/QALY, and $150,000/QALY. Uncertainty in these outcomes was assessed with probabilistic sensitivity analyses. Key model parameters included the efficacy of esketamine versus oral antidepressants (relative risk of 1.39 for remission; 1.32 for response) and the monthly cost of esketamine ($5,572 for month 1; $1,699-$2,244 thereafter). RESULTS Over 5 years, esketamine was projected to increase time in remission from 25.3% to 31.1% of life-years, resulting in a gain of 0.07 QALYs. Esketamine increased societal costs by $16,617 and health care sector costs by $16,995. Base case ICERs were $237,111/QALY (societal) and $242,496/QALY (health care sector). Probabilistic sensitivity analysis showed a greater than 95% likelihood that esketamine's ICER would be above $150,000/QALY. At a cost-effectiveness threshold of $150,000/QALY, esketamine's value-based price was approximately $140/dose (versus a current price of $240/dose). CONCLUSIONS Esketamine is unlikely to be cost-effective for management of treatment-resistant depression in the United States unless its price falls by more than 40%.

Abstract
This narrative review aims to provide an overview of the current literature on the pharmacology, safety, efficacy and tolerability of intranasal esketamine, the S-enantiomer of ketamine, for the treatment of treatment-resistant depression (TRD). A literature search using Medline, Embase, PsycINFO and Cochrane Central was conducted (January 2000 to July 2019). Product information and www.clinicaltrials.gov were also reviewed. The literature search was limited to human studies published in English. Phase I, II, and III studies of intranasal esketamine for TRD were reviewed. About a third of patients with major depressive disorder fail to achieve remission despite treatment with multiple antidepressants. This article examines the trials that led to the approval of esketamine in the United States, as well as other recent studies of esketamine for TRD. The findings from limited phase III trials illustrate that intranasal esketamine is effective and safe in reducing depressive symptoms and achieving clinical response in patients with TRD. The optimum duration and frequency of use are not fully understood. Although the nasal spray is a convenient dosage form, its use in practice may be limited by cost and administrative regulation. While it may prove beneficial to many patients who suffer from TRD, further long-term data are required, along with comparative trials with the R-isomer (arketamine). In the interim, care and monitoring should be exercised in its use in clinical practice.

Abstract
Major depression affects millions of adults in the United States, and women are affected at twice the rate of men. Approximately 30% of individuals may continue to experience depression symptoms despite treatment with oral antidepressants. In March 2019, the U.S. Food and Drug Administration approved esketamine (Spravato), which is specifically indicated for treatment-resistant depression. Available as a nasal spray in a health care office or facility, esketamine has the potential to fill an unmet need for individuals who continue to experience depression with conventional treatment. Symptom improvement may be seen as rapidly as 1 week after treatment initiation. This article provides an overview of esketamine, including administration, adverse effects, and practice implications for women's health nurses.

Abstract
Depression represents one of the most common and debilitating mental illnesses in the world today. Despite this pressing issue, the majority treatments for depression give patients therapeutic response only approximately half of the time, with many not responding at all. In part, this stagnation has been due to the dominance of the monoamine hypothesis that guides the current approach to understanding and treating depression. While therapies that increase levels of monoamines have been useful, clearly a more complete understanding of the neural circuits and treatments is needed to better help patients. Recent work that exploits the glutamatergic system within the brain has demonstrated a functional role for glutamate in combatting depression. While more research is required to understand the specific glutamatergic pathophysiological mechanisms within depression, emerging clinical work has already demonstrated promising results. Current treatments that target the glutamatergic system, especially NMDA receptor antagonists have already shown efficacy in several clinical trials. In this chapter we briefly introduce a mechanistic basis for a role of glutamate in the pathophysiology of depression. We further review basic and translational studies that describes potential mechanisms and roles for glutamate. A discussion of the first promising NMDA receptor antagonist for depression, ketamine, follows afterward. The development of NMDA receptor antagonists for treatment of depression is chronicled, from initial studies up through the recent FDA approval of intranasal esketamine as well as other newer compounds that have shown recent promise in clinical trials.

Abstract
Ketamine, a dissociative anesthetic and psychedelic compound, has revolutionized the field of psychopharmacology by showing robust, and rapid-acting antidepressant activity in patients suffering from major depressive disorder (MDD), suicidal tendencies, and treatment-resistant depression (TRD). Ketamine's efficacy, however, is transient, and patients must return to the clinic for repeated treatment as they experience relapse. This is cause for concern because ketamine is known for its abuse liability, and repeated exposure to drugs of abuse often leads to drug abuse/dependence. Though the mechanism(s) underlying its antidepressant activity is an area of current intense research, both clinical and preclinical evidence shows that ketamine's effects are mediated, at least in part, by molecular adaptations resulting in long-lasting synaptic changes in mesolimbic brain regions known to regulate natural and drug reward. This review outlines our limited knowledge of ketamine's neurobiological and biochemical underpinnings mediating its antidepressant effects and correlates them to its abuse potential. Depression and addiction share overlapping neural circuitry and molecular mechanisms, and though speculative, repeated use of ketamine for the treatment of depression could lead to the development of substance use disorder/addiction, and thus should be tempered with caution. There is much that remains to be known about the long-term effects of ketamine, and our lack of understanding of neurobiological mechanisms underlying its antidepressant effects is a clear limiting factor that needs to be addressed systematically before using repeated ketamine in the treatment of depressed patients.
