Form selection requires an interdisciplinary approach involving a complex process to discover, monitor, and evaluate the solid-state characteristics, biopharmaceutical properties, stability, and processability of numerous forms. This Perspective discusses the importance of aligning critical material attributes with the desired quality target product profile to ensure drug safety and efficacy. It discusses how the form selection strategy is dependent on factors related to the administration route, dosage form, and therapeutic indication and provides an interdisciplinary framework with four prioritized sets of target attributes for oral delivery: solid-state properties, biopharmaceutical performance, stability, and processability. A classification system to guide form selection, particularly for immediate-release oral medications, is reviewed. The benefits of crystalline forms in terms of stability and processability are highlighted, emphasizing the role of solution crystallization in controlling their development. The interdisciplinary form selection process will be demonstrated through case studies highlighting how each set of target attributes were evaluated leading to the selection of ideal forms for development.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"58 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, controlled semibatch reactions are optimized to achieve complete conversion and formation of mononitro products with very high selectivity for 5-nitrosalicylic acid (5-NSA). Further, the combination of computational fluid dynamics simulations and experiments is employed to optimize CIJR design and operating flow conditions, suitable to yield only mononitro products with excellent control over mixing, heat transfer, and liberation of fumes during continuous flow reaction. Detailed analysis of internal flow patterns, rate of heat generation, and concentration distribution inside the CIJR facilitated the optimization of present exothermic reaction in a safe manner. In less than a minute, complete salicylic acid (SA) conversion with good yield and better selectivity for 5-NSA is achieved using the CIJR. Safety and clogging issues are addressed effectively, even at a relatively lower mole ratio (1:5) of SA:acetic acid (AcOH). The present approach is quite scalable using the numbering-up strategy, with advantages viz. nonfouling, high throughput, and the small footprint of CIJR.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"74 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143021130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we showcase the successful implementation of PAT for monitoring bioconjugation reactions related to both vaccine and biologic pharmaceutical manufacturing processes. Specifically, we explore a variety of PAT-based techniques and their utility for monitoring polysaccharide–protein and protein–small molecule bioconjugation reactions.

The active pharmaceutical ingredient (API) has an (<i>R</i>,<i>R</i>) configuration and three minor stereoisomers, including (<i>R</i>,<i>S</i>), (<i>S</i>,<i>R</i>), and (<i>S</i>,<i>S</i>) isomers. During pharmaceutical formulation development, methanol adducts were found in spray-dried dispersion (SDD) materials at alarming levels. To investigate the formation mechanism of methanol adducts, we successfully developed an ultrahigh performance liquid chromatography achiral method and a supercritical fluid chromatography chiral method to separate all potential methanol adducts and stereoisomers of BMS-986409. It is concluded that ring-opening at the 2-position of the gluarimide moiety (Pathway 1) is the favored formation mechanism of methanol adducts during the BMS-986409 SDD manufacturing process and epimerization can be neglected. However, under basic conditions, ring-opening at the 6-position of the gluarimide moiety (Pathway 2) becomes dominant and, in the meantime, epimerization is promoted to a great extent. The knowledge collected by leveraging the SFC chiral method gives us the needed confidence in the analytical impurity control strategy that solely relies on the achiral method for monitoring methanol adduct impurities in SDD materials and sample release in future pharmaceutical development.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"21 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142989451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solvent screening was conducted by means of the crystallization of the cocrystal from a saturated solution of acetone, ethanol, isopropanol, acetonitrile, ethyl acetate, and ethyl formate. Two selected solvents, namely, ethyl formate and acetone, were subjected to ternary phase diagram construction in order to ascertain the system equilibrium and identify the boundaries for pure cocrystal crystallization. The crystallization process was subsequently examined through the utilization of an in situ Raman spectroscopy probe. It was observed that the rate of transformation decreased at higher temperatures, which is most probably due to lower saturation in terms of the cocrystal. The reaction mechanism was observed by an in situ imaging probe, showing that new crystals were growing directly from the solution instead of growing from the surface of existing crystals. These findings were employed in the development of a crystallization process for both solvents, resulting in enhanced time and cost efficiency. A notable difference in particle size was observed between solvents, with acetone producing larger crystals. Consequently, ethyl formate was selected as the optimal solvent for further scale-up of the process, given its favorable impact on dissolution enhancement.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"30 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142987097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
