Download or read book Development of New Tools for the Production of Plasmid DNA Biopharmaceuticals written by Diana Morgan Bower and published by . This book was released on 2012 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA vaccines and gene therapies that use plasmid DNA (pDNA) as a vector have gained attention in recent years for their good safety profile, ease of manufacturing, and potential to treat a host of diseases. With this interest comes increased demand for high-yield manufacturing processes. Overall, this thesis aims to develop new, innovative tools for the production of plasmid DNA biopharmaceuticals. As one part of this thesis, we designed a 1-mL fed-batch microbioreactor with online monitoring and control of dissolved oxygen, pH, and temperature, as well as continuous monitoring of cell density. We used the microbioreactors to scale down temperature-induced production of a pUC-based DNA vaccine vector, pVAX1-GFP. Scaled-down processes can facilitate high-thoughtput, low-cost bioprocess development. We found that the microbioreactors accurately reproduced the behavior of a bench-scale bioreactor as long as key process parameters, such as dissolved oxygen, were held constant across scales. The monitoring capabilities of the microbioreactors also provided enhanced process insight and helped identify conditions that favored plasmid amplification. A second aspect of this thesis involved construction and characterization of a new DNA vaccine vector based on a runaway replication mutant of the R1 replicon. Runaway replication plasmids typically show increased amplification after a temperature upshift. However, we found that our new vector, pDMB02-GFP, gave higher yields during constant temperature culture at 30"C, reaching a maximum of 19 mg pDNA/g DCW in shake flasks. We gained mechanistic insight into this behavior by measuring RNA and protein expression levels of RepA, a plasmid-encoded protein required for initiation of replication at the R1 origin. Through these studies we found that RepA levels may limit plasmid amplification at 42*C, and relieved this limitation by increasing RepA translation efficiency via a start codon mutation. We also scaled up production of pDMB02-GFP at 300C from 50-mL shake flasks to 2-L bioreactors. Initial scale up efforts resulted in increased growth rate compared to the shake flasks, accompanied by very low plasmid yields. Decreasing the growth rate by limiting dissolved oxygen increased plasmid specific yield and emerged as a viable strategy for maintaining productivity during scale up.
Download or read book Delivery Technologies for Biopharmaceuticals written by Lene Jorgensen and published by John Wiley & Sons. This book was released on 2009-10-23 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in biotechnology have provided scientists with an increasing number of biopharmaceuticals such as novel peptide and protein drugs as well as nucleic acid based drugs for gene therapy. However, successful delivery of these biopharmaceuticals is a major challenge because their molecular properties lead to poor physical and chemical stability in the body and limited membrane permeability. Therefore researchers are developing a range of new delivery technologies and materials to enable these new drugs to be delivered intact to their target sites. Delivery Technologies for Biopharmaceuticals describes strategies to overcome the main barriers for successful delivery of therapeutic peptides, proteins, and nucleic acid-based drugs or vaccines related to the site of administration and the target site. Many of the approaches described are reported in formulations in current clinical trials as well as in marketed products. Contents include: challenges in delivery of biopharmaceuticals novel formulation approaches for peptide and protein injectables non-viral chemical vectors and viral technology for delivery of nucleic acid based drugs immune response, adjuvants and delivery systems for vaccines several examples of delivery systems for different biopharmaceuticals a critical assessment of delivery technologies for biopharmaceuticals Delivery Technologies for Biopharmaceuticals is an essential single-volume introduction to the technologies used by researchers to ensure efficient delivery of this exciting new class of drugs.

This book was released on 2023-06-15 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year for the past three years, there have been about 50 new molecular medicines approved by the United States Food & Drug Administration (FDA), of which approximately 25% were new biopharmaceuticals. Over 200 recombinant proteins, monoclonal antibodies, antibody drug conjugates, fusion proteins, and Fab fragments are now in the marketplace in both the United States of America (USA) and European Union (EU). There are also now over 60 biosimilars available for all major classes of recombinant proteins and monoclonal antibodies. In addition, gene therapies using genetically engineered viruses and genetically engineered cells are now in the marketplace, and continually growing. This degree of change is reflected in the over 400 CMC regulatory compliance references listed in this book that were either issued or updated since the release of the third edition. Deficiencies in biopharmaceutical CMC regulatory compliance rarely result in termination of a product, but in can readily cause months if not years of delay in initiating clinical trials, or advancing clinical development stages, or even market approval. In summary, this book: Updates real-world CMC deficiency examples with current examples; Addresses current FDA and EMA requirements and expectations for CMC regulatory compliance; Now includes CMC regulatory compliance for the new gene-based biopharmaceuticals.

Download or read book Biopharmaceutical Drug Design and Development written by Susanna Wu-Pong and published by Springer Science & Business Media. This book was released on 1999-04-01 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: New discoveries in biology are occurring at an incredible rate, and with these discoveries arise nearly unimaginable opportunities in every area of human existence. Imagine the excitement surround ing the "penicillin project" and the subsequent rapid development of anti-infective agents that took place in the 1940s and 1950s. Fast for ward to the world today and our ability to treat life-threatening infec tions. This is but one small piece in the present kaleidoscope of new therapeutic agents. In fact, the world of science, biology, and medi cine is changing so quickly that it is difficult for scientists and medi cal practitioners to stay abreast of their fields and confidently anticipate that their education and training will sustain them over a three- to four-decade career without considerable continuing educa tion and training. For the pharmaceutical scientist responsible for the discovery and development of therapeutic agents based on advances in biotechnology, it is imperative to quickly come up to speed and stay at the forefront of developments, which is no easy task for those not specifically trained in this area. Biopharmaceutical Drug Design and Development, edited by Susanna Wu-Pong and Yongyut Rojanasakul, cuts a potentially wide swath in terms of its intended audience. It clearly is a primer for those not trained in the area, or for those who wish to be brought into the mainstream of drug discovery and development in the world of bio technology.
