Cost-Effectiveness Analysis of Second-Generation Antipsychotic Long-Acting Injectables in Patients with Schizophrenia in the United States (ISPOR 2025) - "Our objective was to compare the cost-effectiveness of four intramuscular SGA LAIs (aripiprazole, aripiprazole lauroxil, olanzapine pamoate, and risperidone) to paliperidone palmitate in patients with schizophrenia from the US health care sector perspective...Patients transitioned to additional lines of therapy (another SGA LAI and then clozapine) when they experienced relapse or intolerance to side effects... Our estimation of 5-year costs and outcomes demonstrated similar total costs and QALYs across the SGA LAIs. Further studies to refine model inputs are needed to better differentiate between the SGA LAIs and to validate our findings."

Shortage antipsychotic medication supply hits vulnerable patients most (PubMed, Ned Tijdschr Geneeskd) - "The intramuscular depot of olanzapine (Zypadhera) was not available over a long period of time...Therefore, the medication shortages can have a life altering effect. As healthcare workers we feel obliged to report about the consequences of the severity of the rising number of medication shortages and highlight the consequences of the vulnerability of psychiatric patients."

Clozapine-induced myocarditis – prevention, detection, and management (ECNP 2024) - "Recent findings indicate that the efficacy of clozapine re-initiation is superior compared to alternative approaches including treatment with olanzapine, long-acting injectable antipsychotics, and electroconvulsive therapy. To date, there is clear evidence for the singular importance of slow clozapine titration regimes to reduce side-effect rates. Importantly, combining this approach with a safe minimum CIM screening regime could increase global clozapine use. Finally, establishing a consensus regarding the minimal requirements for monitoring algorithms will aid in determining a balance between patient safety and the burden of CIM screening."

Long-acting subcutaneous injectable olanzapine (TV-44749) demonstrates efficacy in patients with schizophrenia: Results from a randomised, double-blind, placebo-controlled trial (SOLARIS) (ECNP 2024) - P3 | "The Subcutaneous OLAnzapine extended-Release Injection Study (SOLARIS; NCT05693935) is an ongoing phase 3 study designed to assess the efficacy, safety and tolerability of TV-44749 in patients with schizophrenia. In patients with schizophrenia, once-monthly subcutaneous TV-44749 demonstrated significantly greater efficacy versus placebo with no reported PDSS. TV-44749 may provide an effective LAI olanzapine formulation while avoiding the risk of PDSS and will be further studied in the open-label, long-term safety period of SOLARIS."

Therapeutic drug monitoring of long-acting injectable antipsychotics and psychopathological assessment in schizophrenia spectrum disorders: a longitudinal characterisation of relapse risk (ECNP 2024) - "LAI antipsychotics were aripiprazole (41.3%), olanzapine pamoate (26.1%), paliperidone palmitate once monthly (13.0%), paliperidone palmitate every 3 months (19.6%)... The present study suggests a role for TDM in real-world practice, as finding under-range LAI plasma levels in clinically stable outpatients may prompt monitoring for relapses especially in younger patients. Moreover, the study suggests that relapses in patients with adequate LAI antipsychotic plasma levels may be tied to worse affective and negative symptoms, and to a worse subjective experience of treatment - underlining the need for a thorough psychopathological assessment beyond psychotic symptoms."

Results from Period 1 of the SOLARIS trial indicate that the safety profile of TV-44749 was consistent with other approved formulations of olanzapine, no new safety signals were identified, and there were no reported cases of PDSS. Safety and tolerability will be further investigated in the open-label, long-term safety period of SOLARIS."

A long-acting subcutaneous injectable formulation of olanzapine is designed to eliminate the causes of post-injection delirium/sedation syndrome (ECNP 2024) - "Introduction Use of the intramuscular (im) formulation of olanzapine (Zyprexa Relprevv, Eli Lilly) has been limited because of a black-box warning of post-injection delirium sedation syndrome (PDSS) and associated REMS. Overall the sc route of administration and formulation characteristics of TV-44749 appear to eliminate the causes of PDSS. These Results are further supported by the lack of PDSS events in the phase 1 study."

TV-44749, A Long-Acting Subcutaneous (sc) Injectable Formulation of Olanzapine is Designed to Provide Sustained Controlled Concentrations and to Eliminate the Causes of Post-Injection Delirium/Sedation Syndrome (PDSS) (SIRS 2024) - "The results show that both APIs were stable in human plasma, however, olanzapine base in crystalline form II in TV-44749 showed 1.8 times lower solubility than olanzapine pamoate monohydrate of the IM formulation. For the IM formulation, 39% of olanzapine is released within first 0.5 h with complete release achieved within 24 hours. For TV-44749, only 3% of olanzapine is released within 4 hours and at the end of IVR experiment at 72 hours, only 14% of olanzapine is released."

Prevention, Detection, and Management of Clozapine-Induced Myocarditis (SIRS 2024) - "Moreover, recent findings indicate that the efficacy of clozapine re-initiation is superior compared to alternative approaches including treatment with olanzapine, long-acting injectable antipsychotics, and electroconvulsive therapy. Slowing clozapine titration rates and early routine use of therapeutic drug monitoring (TDM) can reduce the risk of dangerously fast increases in plasma clozapine levels which constitutes an established risk factor for CIM.

Additionally, stringent CIM screening and management ensure timely detection of CIM thus increasing patient safety and the chance for a restitutio ad integrum."

Evaluation of Patient Assistance Programs and Eligibility Criteria Offered for Long-Acting Antipsychotics Used in Patients With Schizophrenia (APA 2023) - "Of those, 70% (8/10) offer a PAP which covers the full cost for uninsured US residents, including: Abilify Maintena, Abilify Aristada, Invega Sustenna, Invega Trinza, Invega Hayfera, Risperdal Consta and Haldol Decanoate. With LAI’s such as Zyprexa Relprevv, Prolixin and Perseris being the exceptions... While these PAP’s cover the entirety of the cost of most of the available medications for those without insurance, they only aid a small subset of the population of patients suffering from schizophrenia. Efforts will need to be made to decrease the gap between costs of treatment and available financial assistance programs, especially for those expereincing financial difficulty who have some form of medical insurance and high copayments."

A combination of bromocriptine and physostigmine followed by rivastigmine is proposed to manage PDSS if patients develop severe dopamine blockade or anti-cholinergic delirium."
