The biopharmaceutical industry has long been working on methods to delivery biologic therapeutics in a manner that will enhance ease-of-use and patient compliance. Biologics today are largely administered parenterally, a method that can be painful and undesirable for patients. Furthermore, parenteral formulations of biologics require a strict temperature-controlled environment. Researchers have long been exploring means to formulate biologic-based molecules that can ensure their molecular stability and mitigate some of the stringent manufacturing requirements. In this episode of the Drug Solutions podcast, Feliza Mirasol, science editor of Pharmaceutical Technology®, Pharmaceutical Technology EuropeTM, and BioPharm International® explores the issues challenging biologic formulation and the progress made so far in moving toward alternative routes of biologic drug delivery with Nigel Theobald, CEO of N4 Pharma, a specialist pharmaceutical company developing novel delivery systems for oncology, gene therapy and vaccines.
