However, the quality attributes for biological products do not have a systematic naming taxonomy, and consequently this limit poses a critical challenge in the development of systems for structured regulatory submissions. Here, we describe the creation of a controlled vocabulary with a structured taxonomical naming approach for quality attributes of therapeutic proteins. Additionally, we endeavor to make the case for why such systematic harmonized naming is required to support the successful implementation of structured data systems. We also describe the key principles of our structured naming approach, including a top-down view of the product and protein structure and a distinction between a quality attribute and the test to evaluate the attribute. Finally, we describe how this approach can accommodate emerging product types, advanced manufacturing technologies, and be used across the variety of submission sections in a regulatory dossier that discusses quality attributes.","PeriodicalId":453,"journal":{"name":"AAPS Open","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"An in-silico approach towards multivariate acceptable ranges in biopharmaceutical manufacturing","authors":"Marco Kunzelmann, Judith Thoma, Sabrina Laibacher, Joey M. Studts, Beate Presser, Julia Spitz","doi":"10.1186/s41120-024-00095-y","DOIUrl":"https://doi.org/10.1186/s41120-024-00095-y","url":null,"abstract":"Multivariate interactions between process parameters can heavily impact product quality and process performance in biopharmaceutical manufacturing processes. Thus, multivariate interactions should be identified and appropriately controlled. This article describes an in-silico approach to establish multivariate acceptable ranges; these ranges help to illustrate the combined impact of multiple input variables on product quality and process performance. Additionally, this article includes a case study for a monoclonal antibody polishing application. Proven acceptable ranges are set by changing only one input parameter at a time while keeping all others constant to understand the impact of process variability on product quality or process performance, but the impact of synergistic variables are not evaluated. Within multivariate acceptable ranges, any combination of input parameters of a unit operation yields the desired product quality and process performance. The layered approach applied in this article is based on risk assessment and statistical models to leverage prior knowledge and existing data. The risk assessment is specific for a manufacturing facility but is applicable to multiple products manufactured in the same facility. No additional wet-lab experiments are required for building the statistical models when development and process characterization are executed using a design of experiments approach, compared to a univariate evaluation of data. The established multivariate acceptable range justifies revised normal operating ranges to ensure process control. Further, the determination of multivariate acceptable ranges adds to overall process knowledge, ultimately supporting the implementation of a more effective control strategy.","PeriodicalId":453,"journal":{"name":"AAPS Open","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141503947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study found that all n = 15 samples purchased from 14 websites were problematic regarding their package, labeling, and/or content. Specifically, one sample (6.7%) was confirmed falsified, twelve samples (80%) were found either to be falsified or unlicensed as pharmaceutical product, and two samples (13.3%) were received without information on the manufacturers’ physical address or country of origin, with one sample (6.7%) having no labeling or other accompanying information at all. Both Raman spectrometers were able to identify the API in all samples as confirmed and quantified by ultra-high-performance liquid chromatography–Fourier transform mass spectrometry. Twelve samples contained on average less than 90% of the declared API content. By contacting national regulatory authorities in 44 countries, methandienone products were found to be approved in 1 country and not approved in 21 countries. To prevent health hazards and abuse, measures against the acquisition of anabolic-androgenic steroids from unknown sources are required.

The aim of this study was to obtain the initial data needed about the effects of various CPEs on the skin permeation of OLZ. The effects of the selected CPEs were examined by studying the permeation profiles of OLZ from formulations applied to human cadaver skin samples. A control formulation of OLZ in propylene glycol (PG) was prepared and compared against formulations containing chemical penetration enhancers. Five different CPEs (oleic acid (OA), cineole (Cin), isopropyl alcohol (IPA), Tween 80 (T80), and N-methyl pyrrolidone (NMP)) at 5% w/w were individually added to the formulation containing OLZ in PG. The in vitro permeation study was carried out using vertical Franz diffusion cells mounted with human cadaver skin. Samples from the receptor compartment of the cell were collected at 2 h, 4 h, 8 h, 12 h, and 24 h at room temperature. The amount (µg/cm2) of permeated drug (OLZ) was measured using a validated HPLC method, and the percentage (%) of OLZ permeated was calculated. Based on the data obtained, different CPEs were found to have a significant impact on OLZ permeability compared to the control formulation. The most effective chemical penetration enhancer was shown to be 5% w/w OA with a 3.3-fold increase in enhancement ratio (ER). The rank of order for the highest concentration of OLZ permeated from each of CPE containing formulation was as follows: OA > Cin > IPA > T80 > NMP. The most effective chemical penetration enhancer was OA but the cytotoxic study using human fibroblast cells suggests that OA may not be safe due to its cytotoxic effects.","PeriodicalId":453,"journal":{"name":"AAPS Open","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140829677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most important dosage form characteristics are a detailed active pharmaceutical ingredients dissolution release profile evaluation obtained through dissolution testing. The dissolution test is used in the development of both brand-name and generic drugs. Prior to beginning bioequivalence studies, it is critical to compare the dissolution profiles of various pharmaceutical products. As a result, dissolution is a critical quality control parameter for drugs because it has a direct impact on absorption of pharmaceutical products. Dissolution profile evaluation of seven brands of amoxicillin-clavulanate potassium tablets is retailed in Hawassa town, Sidama Regional State, Ethiopia. The seven brands of amoxicillin-clavulanate potassium tablets were collected from Hawassa town, Sidama Regional State, Ethiopia. The dissolution study was conducted as per USP40-NF35. Then, the dissolution profile test results were compared by one-way ANOVA Dunnett’s test, model independent, and model dependent method. All of the included brand tablets complied with a single-point dissolution study specification. All brand tablets had similar dissolution profiles (p > 0.05), difference factor (f1) < 15%, and dissolution efficiency $$(le 10varvec{%}$$ ). However, the f2 (similarity factor) value justifies that all brand tablets were not within USFDA specification ( $$ge$$ 50%). The evaluated brands followed the Korsemeyer-Peppas followed by the Weibull curve models. All brand tablets passed the single point USP dissolution specification and the USFDA therapeutic interchangeability guideline. The similarity factor (f2), on the other hand, confirmed that none of the tested brand tablets were interchangeable with the innovator product. Therefore, researchers, national medicine regulatory bodies, and the manufacturer should conduct a properly designed dissolution test as proof of an in vitro bioequivalence study supported by in vivo bioavailability data. Dissolution profile evaluation of seven brands of amoxicillin-clavulanate potassium tablets retailed in Hawassa town, Sidama Regional State, Ethiopia. Why was the study done? Ever since a medicine must dissolve before it can be absorbed. Because the rate at which a drug dissolves from a dosage form generally influences the rate and amount of absorption. The Food and Drug Administration (FDA) should recommend that amoxicillin and clavulanate potassium are well absorbed from the gastrointestinal tract after oral administration of Augmentin with no significant difference in absorption after oral administration. When given orally, drugs with slow dissolution rates have intermittent and inadequate absorption, resulting in limited bioavailability.

Coprocessing is a promising technique in the pharmaceutical industry which support both drug substance and drug product processes. When active pharmaceutical ingredients (APIs) are coprocessed with excipients, it can enable direct compression and continuous manufacturing. Hydroxypropyl cellulose (HPC-L), a commonly used excipient in pharmaceutical formulations, can enhance drug stability, solubility, and bioavailability. In this study, we have employed coprecipitation (CPT) to coprocess metformin hydrochloride (MET) with HPC-L, resulting in the formation of agglomerates with improved physical attributes without any risk of polymorphic changes. Acetone/acetonitrile and heptane were used as solvent and antisolvent, respectively. Screening study revealed that the use of a rotor stator helps to control the size of metformin hydrochloride and HPC-L agglomerates (M-CPT) without negatively impacting bulk density and powder flow properties. The CPT agglomerates showed residual solvent levels within the specified ICH limits. Powder rheology results demonstrated a sixfold increase in FFC of M-CPT compared to neat MET. The compressibility, tabletability, compactability, and “In-Die” Heckel analysis data further suggested that the M-CPT agglomerates are directly compressible with no observable changes in the dissolution profile of MET. Overall, this study demonstrates application of CPT approach to tune the physical and mechanical properties, and HPC-L can be used as an excipient of choice for CPT technique to improve the compressibility and flowability of APIs.

However, the product-specific guidance (PSG) for 1% clotrimazole (CLZ) topical cream does not provide an in vitro option for biowaiver and requires a clinical endpoint study to demonstrate bioequivalence (BE). Therefore, the main objective was to use IVRT to investigate pharmaceutical equivalence of several 1% CLZ topical creams from two countries — South Africa (SA) and Canada. This investigation aims at demonstrating the utility of IVRT to determine ‘sameness’ and/or differences between topical creams containing 1% CLZ and the potential of IVRT for supporting biowaivers, thereby obviating the necessity to conduct clinical endpoint studies in patients. A validated IVRT method was applied to conduct comparative IVRT runs on five generic products marketed in SA and one Canadian generic, which were compared against a relevant comparator product from their country of origin in accordance with the FDA’s acceptance criteria of 75–133.33%. All five SA-marketed generic creams showed pharmaceutical inequivalence to the SA comparator product indicating Q1/Q2/Q3 differences. Despite containing the same excipients as both comparator products, the Canadian generic showed substantially lower release rate compared to the comparator products which could be attributed to Q2/Q3 differences. The IVRT method displayed the requisite ability to assess the various 1% CLZ creams and confirmed the potential of the IVRT method to support a biowaiver for 1% CLZ topical creams.
