Currently the characterization of AAV degradation, especially the chemical degradation of capsid, has been limited due to lack of suitable methods. Our study using AAV9 as a model molecule shows that anion exchange chromatography (AEX) as a charge-based separation method has limitations in monitoring the chemical degradation of AAV9 capsid due to a confounding effect from DNA cargo ejection. We developed a hydrophobic interaction chromatography (HIC) method, free from DNA interference, that could serve as a quick and reliable alternative to resource-demanding peptide mapping method for monitoring AAV capsid chemical degradation.

Therefore, there is an urgent need to develop highly accurate and effective theranostic strategies for B-cell lymphoma. In this study, we designed a poly (lactic-co-glycolic acid) (PLGA)-based theranostic nanoplatform (denoted as TscNPs) to achieve ultrasound (US)/magnetic resonance (MR) bimodal imaging-guided photothermal (PTT)/chemo synergistic therapy of B-cell lymphoma. The nanoplatform was conjugated with a CD20 monoclonal antibody specifically targeting B-cell lymphoma to promote tumor accumulation. Encapsulated superparamagnetic iron oxide nanoparticles (SPIONs) as photothermal and MR imaging agents enabled thermal ablation of tumors and imaging-guided tumor therapy. When exposed to near-infrared (NIR) laser, TscNPs generate heat that induces optical droplet vaporization (ODV) of perfluoropentane (PFP), which transforms into microbubbles. This process not only enhanced ultrasound imaging, but also facilitated the release of celastrol (CST) from the nanoplatform, ultimately achieving a PTT/chemo synergistic therapy effect. In the tumor-bearing nude mice model, TscNPs were effectively accumulated in the tumor region. Furthermore, the combined treatment mode of TscNPs and NIR laser irradiation demonstrated a tumor inhibition rate of approximately 96.57%, which was significantly superior to the rates observed with PTT or chemotherapy alone.

However, SWATH MS/MS-based methods can generate biased quantitative results that are highly dependent on the selected reference protein. In this study, we enhanced the accuracy of SWATH-based HCP quantitation relative to a spiked-in reference protein by selecting appropriate reference proteins based on their ranking values. We developed a reliable SWATH-based method for quantifying specific HCPs by adding sodium deoxycholate (SDC) during digestion to enhance both protein detection and quantitation consistency. By combining SWATH-based quantitation with standard addition, we showed its use in measuring HCP levels with good accuracy and reproducibility, confirmed by both targeted MRM-MS/MS and ELISA. Additionally, we demonstrated an automated Spectronaut data analysis workflow can efficiently generate SWATH quantitative results for HCPs in different in-process pools.

In this context, a case study is presented in which spray dried amorphous solid dispersion powders produced by modifying process conditions were characterized by both well-established compendial methods (i.e., laser light diffraction, SEM image analysis, bulk and tapped density, and gas adsorption), as well as a new method combining synchrotron computed tomography (SyncCT) with AI-based image analysis. SyncCT was used to classify and quantify the spray dried particles as hollow spheres and solid particles, giving a more detailed quality measure of the particle shape, as they impact downstream processing differently. Moreover, hollow particle wall thicknesses, as well as internal and external particle surface areas were measured by SyncCT.

These impurities were reported in water, food, tobacco, pesticides, and plastics but received attention in mid-2018 when N-nitrosodimethylamine (NDMA) was reported in valsartan drug products. Subsequently, it was revealed that several small molecule and complex nitrosamine impurities can form in any active pharmaceutical ingredient (API) or drug product in which secondary or tertiary amines are present (as API or as impurities) along with a nitrosating agent. Consequently, regulators have provided several guidelines for the risk assessment of nitrosamine formation during manufacturing, storage, or from contaminated supply chains. This has led to a demand for validated analytical methods that quantify N-nitrosamine impurities in pharmaceutical products. In this study, a highly sensitive and robust analytical method was developed and validated for quantitatively determining up to 15 small nitrosamines at low levels (0.01 ppm) in sartan drug substances.

Although the ICH M9 allows for consideration of BCS-based biowaivers in such cases, voriconazole does not meet the additional requirement of dose proportional pharmacokinetics (PK) over the therapeutic dose range. By contrast, if the classification were based on the FDA solubility criteria that were in place prior to ICH M9 (based on the highest dose strength), voriconazole would belong to BCS class I and thus qualify for the BCS-based biowaiver. Since the highest oral dose strength of voriconazole dissolves very rapidly under all BCS conditions, and comparative in vitro dissolution of different tablet formulations aligns with the demonstration of BE in clinical studies, it seems that the ICH Guideline may be unnecessarily restrictive in the case of voriconazole. Therefore, this review discusses potential revisions of eligibility criteria and the extension of biowaiver approvals to encompass a wider range of appropriate drugs.

However, PS80 is susceptible to hydrolysis, due to the presence of fatty acid esters that can be enzymatically hydrolyzed, The unsaturated bonds in the fatty acids are prone to oxidative degradation when exposed to air, especially in the presence of transition metals such as iron and copper, which may be introduced during production and purification processes or from contamination in raw materials used in drug formulation. The degradation of PS80, particularly through metal-mediated oxidative degradation, poses a significant challenge for the industry. Among the identified trace metals, iron plays a crucial role as the redox reaction between ferrous ion (Fe(II)) and ferric ion (Fe(III)) generates radicals that initiate the degradation process. In order to investigate the impact of iron on PS80 degradation and understand the mechanism of iron-catalyzed oxidation, we utilized charge-reduction mass spectrometry and two-dimensional ion density mapping technologies to characterize the degradation of PS80. This method has proven to be a convenient and effective tool for the quick and detailed profiling of PS80, allowing for visual monitoring and examination of the changes that reflect the difficult-to-identify and easy-to-miss oxidized species of PS80. Additionally, a high-performance liquid chromatography coupled to inductively coupled plasma mass spectrometry method was developed for the separation and measurement of Fe(II) and Fe(III). Through this investigation, we determined that the involvement of Fe(II)/Fe(III) in PS80 degradation is a temperature dependent process. Furthermore, we found citrate not only promotes the conversion of Fe(II) to Fe(III), but it also chelates Fe(III) and prevents its reduction to Fe(II), thus inhibiting the initiation of the PS80 degradation. Therefore, the addition of citrate can be a crucial ingredient for controlling the degradation of PS80 in biologic drug substances and products. Overall, this investigation has provided valuable insights to enhance product stability, optimize processes, and ensure the quality of formulations containing PS80.</p>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142639192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
