Summary:“Lyophilization Process Development and Cycle Design with a Case Study” is the topic of aRAPS pre-approved webinar that GlobalCompliancePanel, a leading regulatory and compliance continuing education training provider, will organize on November 15. Jeff Schwegman, Ph.D., founder and chief executive officer of AB BioTechnologies,will be the Speaker at this session.This course earns up to 1.5 RAC credits towards a participant's RAC recertification upon full completion. ----------------------------------------------------------------------------------------------------------------- Description: Optimized lyophilization cycle design can be an extremely difficult and daunting task for the scientist that is unskilled or under skilled in the process. This is becoming even more prevalent as many of the molecules coming out of discovery are more complex, unstable, and require a very specific, multi component formulation to impart not only good chemical stability and physical stability to the active ingredient, but also good physical stability to the dried solids themselves. Unfortunately, many of the molecules that are used to help stabilize the chemical and physical stability of the active ingredient impart poor physical stability to the dried solids and can make lyophilization cycle design difficult. The development scientist who understands and can apply these principles, will be much better equipped to develop robust cycles that can be used to produce quality products consistently, in the shortest amount of time possible, saving time and money. This webinar will start out with an introduction to thermal characterization including Differential Scanning Calorimetry (DSC) and freeze-dry microscopy (FDM) and how the information gained from these techniques can be used as the foundation for optimized cycle design. Next, the seminar will discuss, in detail, the process of designing the freezing, primary, annealing (if used), and secondary drying protocols for the cycle. In each case, the process will be broken down to understand the correct choice of the different controllable lyopohilizer parameters including shelf temperature, chamber pressure, and hold times. Also discussed, will be some of the specialized tools that can be used to aid the development scientist in cycle development including, the sample thief, the Pirani gauge, and thermocouples. Areas covered in the session: o Thermal characterization including DSC and FDM o Understanding the effects of working with crystalline vs. amorphous components o The problem with working with a metastable glassy system and the use of annealing to correct this problem o Determining optimal shelf temperatures for the freezing step o Determining optimal shelf temperatures and chamber pressures for the primary drying step o Determining optimal shelf temperatures and chamber pressures for the secondary drying step o Characterization of the finished lyophilized product This webinar session imparts the following to its participants: o Learning how to interpret a lyophilization cycle chart o Developing optimal conditions for freezing, primary, and secondary drying o Distinguish between amorphous and crystalline components and how they affect cycle design o Understanding the need and techniques of characterizing the dried solids ----------------------------------------------------------------------------------------------------------------- When:November 15, 10:00 AM PDT 01:00 PM EDT ----------------------------------------------------------------------------------------------------------------- By whom: Jeff Schwegman, Ph. D., develops formulations, lyophilization cycles, determines residual moisture by Karl Fischer, and provides thermal characterization studies including freeze-dry microscopy and DSC at his firm, AB BioTechnologies, of which he is the founder and CEO. Dr. Schwegman specializes in speaking and consulting in parenteral pre-formulation, formulation, analytical, and lyophilization of both small molecules and large biomolecules. He also holds patents and develops new technologies within the lyophilization field. Dr. Schwegman received his BS in Biochemistry from Indiana University in 1992 and began working at Cook Imaging in Bloomington Indiana, where he gained experience in analytical, formulation and process development. In 1999 he began graduate study in the Department of Industrial and Physical Pharmacy at Purdue University. Dr. Schwegman holds patents and develops new technologies in lyophilization. He is also the course Director for a 3-day course called Lyophilization Technology, which he teaches through the Center for Professional Innovation and Education. He routinely lectures around the world on formulation, stabilization and process development of lyophilized products. ----------------------------------------------------------------------------------------------------------------- For whom: The webinar will benefit o Quality Control Scientists o Development Scientists o Production Management professionals o Quality Assurance Professionals ---------------------------------------------------------------------------------------------------------------- Duration:90 minutes ----------------------------------------------------------------------------------------------------------------- To enroll for this webinar, contact webinars@globalcompliancepanel.com Phone: 800-447-9407 AMAZINES.COM
