Formulation

A Formulation Strategy for Quickly Reaching Clinical Trials

The aim of any company making protein-based therapeutics is to get to the clinic quickly with a product formulation that has the best chance of success. Any number of specific formulation development and manufacturing issues can keep such drugs from advancing expeditiously to the clinic. To be successful organizations must balance the strengths and weaknesses of each individual molecule against timelines, budgets, and priorities. Ultimately, it’s not just about deploying the best methodologies and processes, but of applying them appropriately…

A Practical Method for Resolving the Nucleation Problem in Lyophilization

Given the prevalence of lyophilization and the growing pipeline of sensitive biological drugs requiring stabilization, pharmaceutical development and manufacturing personnel need complete, reproducible control over the operation, scale-up, and transfer of their lyophilization processes. To address the nucleation problem, Praxair has developed a step-change technology that adds consistent control to the freezing step of lyophilization. This low-capital, plug-and-play option can be readily implemented on most existing freeze-dryers with minor equipment additions and controls integration. Adoption of the technology requires no…

The Human Network

      Biotechnology is not simply about science or technology, process engineering or cell lines, corporations or regulations. It’s ultimately about the people involved in all these things — and about the people they hope to serve with their biotech aspirations. It’s about scientists and technicians, businessmen and medical professionals, patients and consumers, farmers and governments, all their lives touched in one way or another by the biotechnology industry — some admittedly more than others. Policy decisions made by…

Delivery Technology Reenergizes DNA Drug Development

In vivo delivery of DNA-based biopharmaceutical agents encoding proteins of interest (“DNA drugs”) offers a means for the production of protein by target regions of tissue in a subject. This product class derives activity from an ability to induce sustained endogenous protein expression from recipients’ own cells. These unique characteristics are favorable for multiple applications, several of which are now in clinical testing. Therapeutic Proteins: DNA drugs encoding autologous therapeutic proteins could serve as an alternative to long-term therapy based…

Emerging Analytical Technologies for Biotherapeutics Development

A major goal of pharmaceutical development is to characterize pathways of chemical and physical instability and then to develop strategies to minimize them. Deamidation and oxidation are examples of the former, aggregation a result of the latter. The potential for the presence of multiple variants in protein-based pharmaceuticals highlights a need for analytical methods capable of reliably and accurately identifying and measuring those variants. The ideal analytical method would be sensitive, accurate, linear over a broad range, resistant to sample-matrix…

Tackling Formulation and Delivery

The final hurdle in getting a product to market is the formulation and fill–finish step in process development. By their nature, protein therapeutics are more fragile and require a great deal of work to achieve product stability in final formulations. A cell line can be highly productive and efficient in protein production, but if you can’t stabilize the resulting protein and deliver it to patients intact, that’s a costly and useless exercise. The Formulation and Drug Delivery track of the…
