Abstract
Intra-amniotic infection with Candida species is an uncommon but severe condition with high fetal morbimortality and no established clinical guidelines for its management. We report a Candida albicans intra-amniotic infection diagnosed in a 25-week pregnant woman, successfully treated with high-dose liposomal amphotericin B. Pregnancy was prolonged until 30 weeks, and despite persistently positive Candida cultures in amniotic fluid, a healthy newborn was delivered without evidence of systemic infection. Amphotericin concentration was determined at birth, revealing levels over 30 times higher in mother's and cord blood than in the amniotic fluid, probably explaining the clinical protection despite failure in obtaining fungal clearance.

Abstract
Amphotericin B (AMB) is a polyene macrolide antifungal agent used for treating invasive fungal infections. Liposomal AMB is a lipid dosage form, available as AmBisome, which reduces the toxicity of the drug. A simple HPLC-UV method was developed for the determination of AMB in plasma to study its pharmacokinetic profile in a critical patient receiving AmBisome and treated with extracorporeal replacement therapies. Sample preparation was performed using plasma deproteinization and drug release from liposome by the addition of acetonitrile (ACN)/zinc sulfate and ultrasonication. Chromatographic separation was performed using a C18 column and a mobile phase consisting of phosphate buffer (pH 3.0)/ACN (65/35, v/v). The UV detector was set at 407 nm. The total run time analysis was 23 min. The method was validated according to the standard guidelines and applied to study the pharmacokinetics of AMB in a critical patient. The total run time analysis obtained was shorter than that of the previously reported methods, being useful for therapeutic drug monitoring or pharmacokinetic profile research.

Population pharmacokinetics of liposomal amphotericin B in adults with HIV-associated cryptococcal meningoencephalitis. J Antimicrob Chemother 2022; 78:276-283.

Abstract
BACKGROUND Single, high-dose liposomal amphotericin B (LAmB; AmBisome, Gilead Sciences) has demonstrated non-inferiority to amphotericin B deoxycholate in combination with other antifungals for averting all-cause mortality from HIV-associated cryptococcal meningitis. There are limited data on the pharmacokinetics (PK) of AmBisome. The aim of this study was to describe population PK of AmBisome and conduct a meta-analysis of the available studies to suggest the optimal dosing for cryptococcal meningoencephalitis. METHODS Data from a Phase II and Phase III trial of high-dose, short-course AmBisome for cryptococcal meningoencephalitis were combined to develop a population PK model. A search was conducted for trials of AmBisome monotherapy and meta-analysis of clinical outcome data was performed. RESULTS A two-compartment model with first-order clearance of drug from the central compartment fitted the data best and enabled the extent of inter-individual variability in PK to be quantified. Mean (SD) population PK parameter estimates were: clearance 0.416 (0.363) L/h; volume of distribution 4.566 (4.518) L; first-order transfer of drug from central to peripheral compartments 2.222 (3.351) h-1, and from peripheral to central compartment 2.951 (4.070) h-1. Data for the meta-analysis were insufficient to suggest optimal dosing of AmBisome for cryptococcal meningoencephalitis. CONCLUSIONS This study provides novel insight into the PK of AmBisome at the population level and the variability therein. Our analysis also serves to highlight the paucity of data available on the pharmacodynamics (PD) of AmBisome and underscores the importance of thorough and detailed PK/PD analysis in the development of novel antifungals, by demonstrating the challenges associated with post hoc PK/PD analysis.

Abstract
INTRODUCTION Biopredictive release tests are commonly used in the evaluation of oral medicines. They support decision-making in formulation development and allow predictions of the expected in-vivo performances. So far, there is limited experience in the application of these methodologies to injectable drug products. AREAS COVERED Parenteral drug products cover a variety of dosage forms and administration sites including subcutaneous, intramuscular, and intravenous injections. In this area, developing biopredictive and biorelevant methodologies often confronts us with unique challenges and knowledge gaps. Here, we provide a formulation-centric approach and explain the key considerations and workflow when designing biopredictive assays. Also, we outline the key role of computational methods in achieving clinical relevance and put all considerations into context using liposomal nanomedicines as an example. EXPERT OPINION Biopredictive tools are the need of the hour to exploit the tremendous opportunities of injectable drug products. A growing number of biopharmaceuticals such as peptides, proteins, and nucleic acids require different strategies and a better understanding of the influences on drug absorption. Here, our design strategy must maintain the balance of robustness and complexity required for effective formulation development.

Abstract
Background: Because of the delicate nature of liposomes, bioanalysis of free and liposomal-encapsulated drugs is among the most challenging assays to perform. Current regulatory guidance for bioanalysis is not sufficient to address the complexity of this particular formulation. Method & results: Three individual LC-MS/MS methods to quantify free amphotericin B (10-3000 ng/ml) and encapsulated amphotericin B (100-50,000 ng/ml) in pretreated human plasma and total amphotericin B (100-50,000 ng/ml) in human plasma were fully validated and applied to a bioequivalence study. The acceptance criteria and experimental design of additional validation tests using cross quality control were carefully deliberated a priori and included in the sample analysis as well. Discussion: Additional validation tests are necessary to demonstrate that the measured concentration of the intended component is accurate and free of interference from other coexisting components in the sample. These practices can be used as guidance for future liposomal drug method validation.

Abstract
In the advancement of tumor therapy, in addition to the search for new antitumor compounds, the development of nano-drug delivery systems has opened up new pathways for tumor treatment by addressing some of the limitations of traditional drugs. Liposomes have received much attention for their high biocompatibility, low toxicity, high inclusivity, and improved drug bioavailability. They are one of the most studied nanocarriers, changing the size and surface characteristics of liposomes to better fit the tumor environment by taking advantage of the unique pathophysiology of tumors. They can also be designed as tumor targeting drug delivery vehicles for the precise delivery of active drugs into tumor cells. This paper reviews the current development of liposome formulations, summarizes the characterization methods of liposomes, and proposes strategies to improve the effectiveness of tumor treatment. Finally, it provides an outlook on the challenges and future directions of the field. Graphical abstract.

Abstract
Neurocryptococcosis, a meningoencephalitis caused by Cryptococcus spp, is treated with amphotericin B (AmB) combined with fluconazole. The integrity of the brain-blood barrier and the composition of the cerebrospinal fluid (CSF) may change due to infectious and/or inflammatory diseases such as neurocryptococcosis allowing for the penetration of AmB into the central nervous system. The present study aimed to develop LC-MS/MS methods capable of quantifying AmB in CSF at any given time of the treatment in addition to plasma, plasma ultrafiltrate, with sensitivity compatible with the low concentrations of AmB reported in the CSF. The methods were successfully validated in the four matrices (25 μl, 5-1,000 ng ml-1 for plasma or urine; 100 μl, 0.625-250 ng ml-1 for plasma ultrafiltrate; 100 μl, 0.1-250 ng ml-1 for CSF) using protein precipitation. The methods were applied to investigate the pharmacokinetics of AmB following infusions of 100 mg every 24 h for 16 days administered as a lipid complex throughout the treatment of a neurocryptococcosis male patient. The methods allowed for a detailed description of the pharmacokinetic parameters in the assessed patient in the beginning (4th day) and end of the treatment with AmB (16th day), with total clearances of 7.21 and 4.25 L h-1, hepatic clearances of 7.15 and 4.22 L h-1, volumes of distribution of 302.94 and 206.89 L, and unbound fractions in plasma ranging from 2.26 to 3.25%. AmB was quantified in two CSF samples collected throughout the treatment with concentrations of 12.26 and 18.45 ng ml-1 on the 8th and 15th days of the treatment, respectively. The total concentration of AmB in plasma was 31 and 20 times higher than in CSF. The unbound concentration in plasma accounted for 77 and 44% of the respective concentrations in CSF. In conclusion, the present study described the most complete and sensitive method for AmB analysis in plasma, plasma ultrafiltrate, urine, and CSF applied to a clinical pharmacokinetic study following the administration of the drug as a lipid complex in one patient with neurocryptococcosis. The method can be applied to investigate the pharmacokinetics of AmB in CSF at any given time of the treatment.

Abstract
RATIONALE α-Amanitin is a highly toxic peptide widely found in species of poisonous mushrooms. The matrix effect has been a major obstacle for accurate determination of α-amanitin in plasma samples by liquid chromatography/tandem mass spectrometry (LC/MS/MS). In this study, the strategy to eliminate the matrix effect of α-amanitin with a one-step dilution approach after deproteinization was applied. METHODS Rat plasma samples were processed by protein precipitation with methanol followed by a nine-fold dilution with pure water. The matrix effect value of α-amanitin was 19.7%-22.2% by protein precipitation and then changed to 87.5%-88.7% after dilution. α-Amanitin and the internal standard (roxithromycin) were analyzed on an ACQUITY UPLC® BEH C18 (50 mm × 2.1 mm, 1.7 μm) column within 3.0 min by gradient elution. RESULTS The linear ranges were 0.90-600 ng/mL with a correlation coefficient r >0.9958. A lower limit of quantification (LLOQ) of 0.90 ng/mL was achieved using only 50 μL of rat plasma. The intra- and inter-day precisions for the analyte ranged from 3.2% to 7.5% and 3.1% to 7.1%, respectively, and the accuracy ranged from -5.3% to -8.0%. CONCLUSIONS The matrix effect of α-amanitin was reduced by sample dilution after plasma deproteinization. A reliable LC/MS/MS method for the determination of α-amanitin in rat plasma was developed. This method was successfully applied for a toxicokinetic study of rats after intravenous injection of α-amanitin with a subacute toxicity dose at 0.10 mg/kg.

Abstract
Aim: Our objective was to test the feasibility of developing an LC-free, MS-based approach for high-throughput bioanalysis of humanized therapeutic monoclonal antibodies. Methodology: A universal tryptic peptide from human IgG1, IgG3 and IgG4 was selected as the surrogate peptide for quantitation. After tryptic digestion, the surrogate peptide was fractionated via solid-phase extraction before being subjected to direct infusion-based MS/MS analysis. A high-resolution, multiplexed (MSX = 2) parallel reaction monitoring method was developed for data acquisition. Results & conclusion: This proof-of-concept study demonstrated the feasibility of achieving high-throughput MS-based bioanalysis of monoclonal antibodies using an LC-free workflow with sensitivity comparable to conventional LC-MS/MS-based methods.

Abstract
OBJECTIVES Liposomal amphotericin B is widely used to treat life-threatening invasive fungal infections and has replaced conventional amphotericin B deoxycholate due to its more favourable toxicity profile. Despite the fact that liposomal amphotericin B has been licensed for several decades, there is still a paucity of clinical pharmacokinetic data. An assay for the quantification of amphotericin B is necessary to allow the study of its pharmacokinetics. METHODS A UPLC-photodiode array (PDA) analytical method was developed and validated (linearity, accuracy, precision, dilution integrity, carry-over, selectivity and stability) in accordance with EMA requirements. RESULTS The analytical method was validated over a concentration range of 0.5-50.0 mg/L. Accuracy ranged from 97.6% to 112.1% and within-day repeatability and between-day reproducibility from 1.0% to 6.6% and from 0.4% to 4.6%, respectively, dependent on the concentration. Originally, the goal was to develop an analytical method to separate the liposomal and free amphotericin B fractions, but this was not achieved. Difficulties and bottlenecks encountered are presented. CONCLUSIONS A UPLC-PDA analytical method was developed to quantify total amphotericin B in plasma after the use of liposomal amphotericin B.

Amphotericin B (AmB), an effective polyene drug with broad spectrum antifungal activity, is used for serious fungal infections. Liposomal amphotericin B (LAmB) is a lipid dosage form, which has a significantly improved toxicity profile compared with conventional amphotericin B deoxycholate (DAmB). This study focused on verifying the gender differences in the acute toxicity of LAmB and further exploring its causes. Acute toxicity study of LAmB and DAmB were performed in rats, and toxicity responses and mortality of different sexes were observed and recorded. Concentrations of AmB in rat plasma and tissues were determined by a fully validated UPLC-MS/MS assay. The results demonstrated that LAmB showed significant gender differences in acute toxicity, with more severe toxic symptoms and higher mortality for female rats at different doses, but the same differences were not observed for DAmB under the same condition. To explore the cause of differences, toxicokinetic and tissue distribution studies were performed and the results showed that female animals had higher drug exposure, longer half-life and lower plasma clearance compared to male rats, and the drug was mostly distributed in the liver and kidneys, in which female rats displayed a significant higher concentration than that of male rats.

Abstract
The liposomes have continued to be well-recognized as an important nano-sized drug delivery system with attractive properties, such a characteristic bilayer structure assembling the cellular membrane, easy-to-prepare and high bio-compatibility. Extensive effort has been devoted to the development of liposome-based drug delivery systems during the past few decades. Many drug candidates have been encapsulated in liposomes and investigated for reduced toxicity and extended duration of therapeutic effect. The liposomal encapsulation of hydrophilic and hydrophobic small molecule therapeutics as well as other large molecule biologics have been established among different academic and industrial research groups. To date, there has been an increasing number of FDA-approved liposomal-based therapeutics together with more and more undergoing clinical trials, which involve a wide range of applications in anticancer, antibacterial, and antiviral therapies. In order to meet the continuing demand for new drugs in clinics, more recent advancements have been investigated for optimizing liposomal-based drug delivery system with more reproducible preparation technique and a broadened application to novel modalities, including nucleic acid therapies, CRISPR/Cas9 therapies and immunotherapies. This review focuses on the recent liposome' preparation techniques, the excipients of liposomal formulations used in various novel studies and the routes of administration used to deliver liposomes to targeted areas of disease. It aims to update the research in liposomal delivery and highlights future nanotechnological approaches.

Abstract
The development of nano drug delivery systems (NDDSs) provides new approaches to fighting against diseases. The NDDSs are specially designed to serve as carriers for the delivery of active pharmaceutical ingredients (APIs) to their target sites, which would certainly extend the benefit of their unique physicochemical characteristics, such as prolonged circulation time, improved targeting and avoiding of drug-resistance. Despite the remarkable progress achieved over the last three decades, the understanding of the relationships between the in vivo pharmacokinetics of NDDSs and their safety profiles is insufficient. Analysis of NDDSs is far more complicated than the monitoring of small molecular drugs in terms of structure, composition and aggregation state, whereby almost all of the conventional techniques are inadequate for accurate profiling their pharmacokinetic behavior in vivo. Herein, the advanced bioanalysis for tracing the in vivo fate of NDDSs is summarized, including liquid chromatography tandem-mass spectrometry (LC-MS/MS), Förster resonance energy transfer (FRET), aggregation-caused quenching (ACQ) fluorophore, aggregation-induced emission (AIE) fluorophores, enzyme-linked immunosorbent assay (ELISA), magnetic resonance imaging (MRI), radiolabeling, fluorescence spectroscopy, laser ablation inductively coupled plasma MS (LA-ICP-MS), and size-exclusion chromatography (SEC). Based on these technologies, a comprehensive survey of monitoring the dynamic changes of NDDSs in structure, composition and existing form in system (i.e. carrier polymers, released and encapsulated drug) with recent progress is provided. We hope that this review will be helpful in appropriate application methodology for investigating the pharmacokinetics and evaluating the efficacy and safety profiles of NDDSs.
