Cambridge Healthtech Institute’s Fifth Annual
Rapid Methods to Assess Quality & Stability of Biologics:
Improving Prediction and Screening
Part of CHI's Ninth Annual The Bioprocessing Summit

August 21-22, 2017 | Westin Copley Place | Boston, MA

Assurance of quality and stability of biologic formulations over the course of intended usage is critical in developing safe and efficacious biopharmaceutical products. Increasing regulatory expectations and aggressive development timelines calls for rapid methodologies to predict and assess the quality and stability of biologics. The fifth annual Rapid Methods to Assess Quality & Stability of Biologics conference brings together experts in analytical and formulation development to discuss regulatory expectations, prediction and manipulation for protein stability and instabilities caused by particles, higher order structures and impurities. Conference will provide platform to share case studies, unpublished and innovative work on methods employed in real time and accelerated stability studies, protein aggregates and effective use of DoE for assessment and data comparability from early to late stage development.

Speaker Interview

1:45 How Well Can We Predict Protein-Protein Interactions and Aggregation Propensity Using Molecular Models during Candidate and Formulation Assessment?

Christopher_RobertsChristopher J. Roberts, Ph.D., Professor, Chemical & Biomolecular Engineering, University of Delaware

The presentation will focus on approaches for identifying aggregation-prone proteins and formulation conditions based on different structural models and molecular simulation, compared to experimental results for protein-protein interactions and aggregation rates. Examples will include monoclonal antibodies and globular proteins at low and high concentrations, with a view to both candidate selection and formulation development.

2:15 Divide and Conquer: Comparison of Statistical and Probabilistic Tools for Risk Assessment in Multi-Stage Processes

Olga_YeeOlga Yee, Ph.D., Principal Scientist, Drug Product Science and Technology, Bristol-Myers Squibb

Faster decisions imply acceptance of risks associated with accelerated development of compounds. In this presentation, a risk of success for a drug to meet a specification limit is quantified for a three-stage process using three approaches: worst-case scenario, variance transmission model, and the novel approach of “divide and conquer.” A case study for a biologic drug product lifecycle from drug substance to final delivery is presented.

8:00 High Throughput Sialic Acid Analysis

Yimin Hua, Ph.D., Scientist II, Global Manufacturing Science and Technology - Analytical Science and Technology, Sanofi

The level of sialic acid is a critical quality attribute for therapeutic proteins. The level of sialic acid can be measured through glycan profiling which typically involves lengthy sample preparation procedure and challenges in separation of various glycans. This presentation will talk about a high throughput method with simple procedure for the determination of sialic acid level in glycoproteins. This method is not only QC user friendly, but also can be used for fast screening in product and process development.

8:30 Rapid Minor Variants Identification in Therapeutic Antibodies by an Automatic Off-Line 2D-LC/Q Exactive® System

Jin_LiJin Li, Ph.D., Senior Research Associate, Analytical Development and Quality Control, Genentech, Inc.

Understanding the chemical nature of minor variants in therapeutic proteins is critical for process development and product quality control. The current techniques for minor variant characterization typically require manual fractionation to enrich the low abundance species followed by desalting procedures to make the sample MS compatible. Herein we developed a rapid and automatic off-line 2D-LC/Q Exactive® MS workflow for mass analysis of the minor variants in a therapeutic antibody.

10:30 Novel Approach towards the Evaluation of Critical Quality Attributes and Stability of Proteins

Belinda_PastranaBelinda Pastrana, Ph.D., Full Professor, Department of Chemistry, University of Puerto Rico, Mayaguez Campus

Therapeutic proteins are highly complex molecules; their CQAs require diverse bioanalytical techniques to comply with reporting requirements to regulatory agencies. Ideally a multivariate analysis would also be needed to address stability, yet even under the current state of technology, including proteomic and high resolution, techniques can be costly and time consuming. We have developed a DOE, label free method using Best-in-Class platform technology to aid in addressing this concern.

11:00 Rapid Method for Total Protein Measurement Using SoloVPE Technology – Challenges and Solutions

Hsin-I_PengHsin-I Peng, Ph.D., Associate Manager, Quality Control, Regeneron Pharmaceuticals, Inc.

SoloVPE technology presents a unique platform for protein concentration measurement with key benefits including “no dilution” and “rapid reading.” When exploiting SoloVPE, protein concentration under-estimation is experienced for highly concentrated samples, posing challenges for accurate protein concentration measurement. Our studies show standard curve data collected outside the Beer’s law linear region can unfavorably result in protein under-estimation. Challenges and solutions when using SoloVPE technology for protein measurement will be discussed.

11:30 Punch up Biologic Development with ΔG and the HUNK

Greg Manley, Ph.D., Senior Applications Scientist, Unchained Labs

Developing biologics requires identifying an ideal construct followed by assessing a wide range of formulation space to ensure stability and minimize aggregate. Assessing ΔG is a powerful approach for the quantitative assessment of conformational stability and aggregation. The HUNK automates the tedious and manual task of determining ΔG, allowing for quantitative stability assessment throughout biologic development. We'll discuss how HUNK can be used in conjunction with more traditional approaches to assessing stability and aggregation propensity.

12:00 pm High Throughput Methods to Assess Stability of Biologics During Pre-Formulation and Formulation Development

Smita_RaghavaSmita Raghava, Ph.D., Senior Scientist, Sterile Formulation Sciences, Merck

There is a growing demand in the pharmaceutical industry for developing orthogonal tools to accurately, rapidly, and reproducibly predict protein solution stability behaviors using limited material to improve formulation screening and manufacturability assessment. This presentation will focus on combination of high-throughput technologies and assays for formulation and drug product development of biologics, such as monoclonal antibodies (mAbs) and mAb-based modalities. The overview of tools, their novel implementation, and relationship to commonly conducted “stability studies” will be further discussed using examples of high-throughput workflows, pre-formulation screening, and formulation development/optimization.

2:00 Critical Considerations in the Characterization of Protein Higher Order Structure (HOS) and Its Relationship with Stability and Function

Haripada_MaityHaripada Maity, Ph.D., Research Advisor, Formulation Development, CMC Development, Eli Lilly and Company

Higher order structure (HOS) of a protein can be altered due to both physical and chemical instabilities. Characterization of HOS is important in assessing comparability, formulation and process development. This presentation will discuss the (i) selection of techniques in characterization of HOS, (ii) quantitative and qualitative evaluation of characterization parameters and their sensitivity and precision, and (iii) the effect of chemical “mutagenesis” on HOS, stability and functional properties.

3:00Higher Order Structural View Of The Effects Of Oxidation On The Structure, Stability, And Aggregation Of Interferon Alpha-2a

Dinen D. Shah, Ph.D Candidate, Department of Pharmaceutical Sciences, University of Colorado

Oxidation of therapeutic proteins during their formulation and shelf-life is a persistent challenge facing the biopharma industry. We used IFN-αlpha 2a to obtain a mechanistic understanding of how oxidation affects its structure, stability, aggregation and function. Using high resolution techniques such as 2D NMR helped us to pinpoint the residue level structural changes that correlate with functional changes.

4:45 Understanding & Verifying Flow Imaging Particle Counters

Dean_RippleDean Ripple, Ph.D., Leader, Bioprocess Measurements Group, National Institute of Standards and Technology

Flow imaging instruments can measure particles in biotherapeutics with potentially greater accuracy than light obscuration. However, verification methods for flow imaging instruments are not yet standardized. I will present methods used to verify the performance of flow imaging particle counters.
