CHI's Formulation Strategies for Improved Delivery of Biologics Conference - Overview - Biologics Formulation Delivery Summit - Day 1


2014 Formulation Strategies for Improved Delivery of Biologics 


The safety and efficacy of protein and peptide therapeutics are limited by in vitro and in vivo instability, immunogenicity and short circulating half-lives. CHI's Inaugural Formulation Strategies for Improved Delivery of Biologics conference will discuss new formulation approaches designed to overcome biologics delivery issues through as chemical modifications, new formulations and delivery technologies and advanced analytical tools to characterize protein interactions with excipients. These strategies have the potential to facilitate the development of next generation peptide and protein therapeutics which are safe, efficacious and promote patient compliance.

CHALLENGES AND STRATEGIES FOR FORMULATION AND DELIVERY OF BIOLOGICS
 

8:40 KEYNOTE PRESENTATION: The Growing Role of BioTherapeutics Delivery: Opportunities and Challenges

Julia Rashba-StepJulia Rashba-Step, Ph.D., Senior Director, Novel Delivery Technologies, Pfizer, Inc.

There is a rapidly changing environment with the constantly growing role of Biotherapeutics. The presentation will cover thoughts on the future trends on BioTherapeutics and importance of drug delivery in commercial, clinical differentiation and also the need for enabling technologies. Also it will also cover strategic plans for current and future delivery reflective of needs of Pfizer’s BioTherapeutics portfolio.

9:10 Strategies and Consideration for Developing Parenteral Protein Device Combination Products

Sujit BasuSujit K. Basu, Ph.D., Senior Director, Global Technical Operations, Shire

This talk will discuss various considerations and strategies for developing innovative injectable delivery technologies. Examples will be drawn from our intrathecal delivery programs to discuss role of new approaches such as protein device combinations in successfully delivering injectable biotherapeutics.

9:40 Site-Specific Antibody Modification to the Conserved Nucleotide Binding Site (NBS): Effects on Formulation and Delivery of Advanced Therapeutics

NathanAlvesNathan J. Alves, Ph.D., Post-Doctoral Research Fellow, Indiana University School of Medicine, Indiana

Next generation pharmaceutical antibodies that utilize complex conjugation strategies to endow antibodies with various unnatural functional groups brings new challenges, as well as opportunities, to advance drug delivery formulations with hopes of improving therapeutic efficacy. This talk will discuss some critical aspects to consider when producing antibody conjugates and will draw specifically upon an example of site-specific antibody conjugation through UV crosslinking of functional ligands to the highly conserved antibody NBS.

11:10 Talk to be Announced

11:40 Microfluidics-Assisted Engineering of Protein Formulations

SabiruddinMirzaSabiruddin Mirza, Ph.D., Sr. Research Associate, School of Engineering and Applied Sciences, Harvard University

Protein-based therapies hold an enormous potential for treating many terminal diseases. Nevertheless, the lack of universal technological approaches that enable development of protein formulations with the targeted attributes significantly impedes clinical translation of these advanced therapies. This presentation will overview the use of droplet based microfluidic technology for developing protein formulations with pre-programmed functional characteristics, including size and internal morphology, encapsulation efficiency, and protein release profile.

DEVELOPING STABLE PROTEIN AND PEPTIDE FORMULATIONS FOR BETTER DELIVERY
 

2:00 Chairperson’s Remarks

2:05 Lyophilized siRNA Nanosome Formulation

Tarun MandalTarun Mandal, Ph.D., McCaffrey/Norwood Endowed Professor of Pharmacy & Director, Center for Nanomedicine & Drug Delivery, College of Pharmacy, Xavier University of Louisiana

Sequence specific gene silencing based on RNA interference (RNAi) holds great promise for molecular-targeted treatment of various diseases. However, delivery of siRNA presents a special challenge due to its rapid in vivo degradation, large molecular weight, and polyanionic charge. In this study, cationic lipid (DOTAP)-based non-toxic formulations were developed for the treatment of HCV.

2:35 Highly-Automated Procedures for the Assessment of Protein Formulations 

Russell G. Burge, Ph.D., Application Scientist, Freeslate, Inc.

A highly automated process was devised to prepare and analyze samples for the formulation development of proteins. Automation increased efficiency of the activities compared to current methods and procedures. Forty eight protein formulations were generated together with placebos. Automated procedures were employed for appearance (color, turbidity, and particles),viscosity, and pH testing. Spectrophotometry, chromatography and light scattering were performed using semi automated procedures. Performance of the formulations was evaluated after subjecting the vials to stress conditions.

3:05 Protected Peptide Nanoparticles: Experiments and Brownian Dynamics Simulations of the Energetics of Assembly

Robert Prud'hommeRobert K. Prud’homme, Ph.D., Professor and Director Program in Engineering Biology, Department of Chemical & Biological Engineering, Princeton University

Soluble peptides, susceptible to degradation and clearance in therapeutic applications, have been formulated into protected nanoparticles for the first time through the process of kinetically-controlled, block-copolymer-directed rapid precipitation using Flash NanoPrecipitation. Complimentary Brownian dynamics simulations qualitatively model the nanoparticle formation process. Additionally, the influence of the polymer-peptide interaction energy on the efficiency of nanoparticle protection by polymer surface coverage is elucidated in both experiments and simulations. Approaches to encapsulate, and protect more soluble polypeptide constructs using conjugation strategies will be presented.

3:35 Prefilled Syringe Technologies for Improving Drug Stability and Reliable Plunger Performance for Auto-Injectors Applications
