Can CSL-112 revolutionize atherosclerosis treatment? A critical look at the evidence.

CSL-112, a recombinant human apolipoprotein A-I, holds promise for treating atherosclerotic disease by promoting reverse cholesterol transport. This review evaluates the current evidence on CSL-112's impact on atherosclerotic disease. A search identified studies investigating the effect of CSL-112 on apolipoprotein A-I levels, cholesterol efflux capacity, clinical outcomes, safety profile, pharmacokinetics, pharmacodynamics, and subgroup analysis in patients with atherosclerotic disease. All nine studies consistently demonstrated a dose-dependent increase in apolipoprotein A-I levels following CSL-112 administration. Most studies also reported a corresponding rise in cholesterol efflux capacity. However, the AEGIS-II trial, the largest study to date, did not show a statistically significant reduction in major adverse cardiovascular events in patients with acute myocardial infarction treated with CSL-112 compared to placebo. While some smaller studies suggested potential benefits, particularly in stable atherosclerotic disease, their limitations in size and duration necessitate further investigation. CSL-112 appeared to be generally well-tolerated, with mostly mild or moderate adverse events reported. However, the AEGIS-II trial identified a higher incidence of hypersensitivity reactions in the CSL-112 group, requiring further exploration. CSL-112 demonstrates promise in raising apolipoprotein A-I levels and enhancing cholesterol efflux capacity, potentially promoting reverse cholesterol transport. However, its clinical efficacy for atherosclerotic disease remains unclear. Larger, well-designed trials with longer follow-up periods are necessary to definitively establish its clinical benefit and safety profile before widespread clinical use can be considered. Future research should also explore deeper into the pharmacokinetic and pharmacodynamic profile of CSL-112 and explore its efficacy and safety in different patient subgroups.

Clearing the Fog: A Review of Antipsychotics for Parkinson's-Related Hallucinations: A Focus on Pimavanserin, Quetiapine and Clozapine.

Parkinson's disease is a progressive neurodegenerative disorder characterized by motor and non-motor symptoms, including hallucinations. The use of antipsychotic medications is a common strategy to manage hallucinations associated with Parkinson's disease psychosis (PDP). However, careful consideration is necessary when selecting the most appropriate drug due to the potential risks associated with the available treatment options. Atypical antipsychotics (AAPs), such as Pimavanserin and Clozapine, have effectively controlled PDP symptoms. On the contrary, the support for utilizing quetiapine is not as substantial as other antipsychotics because research studies specifically investigating its application are still emerging and relatively recent. The broad mechanisms of action of AAPs, involving dopamine and serotonin receptors, provide improved outcomes and fewer side effects than typical antipsychotics. Conversely, other antipsychotics, including risperidone, olanzapine, aripiprazole, ziprasidone, and lurasidone, have been found to worsen motor symptoms and are generally not recommended for PDP. While AAPs offer favorable benefits, they are associated with specific adverse effects. Extrapyramidal symptoms, somnolence, hypotension, constipation, and cognitive impairment are commonly observed with AAP use. Clozapine, in particular, carries a risk of agranulocytosis, necessitating close monitoring of blood counts. Pimavanserin, a selective serotonin inverse agonist, avoids receptor-related side effects but has been linked to corrected QT (QTc) interval prolongation, while quetiapine has been reported to be associated with an increased risk of mortality. This review aims to analyze the benefits, risks, and mechanisms of action of antipsychotic medications to assist clinicians in making informed decisions and enhance patient care.
