Cambridge Healthtech Institute’s 2nd Annual
Gene Therapy Bioproduction
Developing Scalable, Cost-Effective Gene Therapy Manufacturing Processes
Part of CHI's Ninth Annual The Bioprocessing Summit

August 24-25, 2017 | Westin Copley Place | Boston, MA


It is an exciting time for gene therapy: therapies on the market, encouraging clinical data and a long list of pharma collaborations. Pricing and reimbursement takes a majority of the headlines but equally important is producing these therapies in a scalable, cost-effective and robust way, all the while developing a clear CMC and characterization profile that satisfies the regulators.

Cambridge Healthtech Institute’s Gene Therapy Bioproduction meeting takes a practical, case-study driven approach to the process development, scale-up and production of gene therapies, tackling key topics such as AAV, lentivirus and retrovirus process development and scale-up, CMO management from early to late-stage development.

The approach to comparability and process qualification will be discussed.

2:45 Lentivirus Development and Scale-Up

Jesse_MillingJesse Milling, Scientist II, bluebirdbio

Lentiviral vectors are an ideal platform for indications requiring long-term, stable expression, but the production processes have historically been limited by scale. This presentation will focus on the evaluation of platforms for the next-generation manufacturing process, with the guiding principles of preserving the comparability of the lentiviral product profile.

3:15 Strategies to Deliver Scalable and Reliable Lentiviral Vector Biomanufacturing

Jeff_BartlettJeffrey Bartlett, Ph.D., CSO, Calimmune Inc.

Large-scale clinical production of lentiviral vectors (LV) using current good manufacturing practice (cGMP) methods comes with significant challenges. We have established the Cytegrity stable cell line system for LV bioproduction and have defined key process, quality and regulatory parameters needed to achieve desired productivity and quality across multiples scales and different bioproduction systems. This approach has allowed the production of LV required for Phase I and II clinical trials, while paving the way for future commercialization.

 BIA separations3:45 High Resolution Monolithic Columns - Enabling Tool for Understanding Viral Structures and Their Purity

Ales Strancar, CEO, BIA Separations

Monolithic resins with open channels and no diffusive pores enabled the HPLC to be extensively applied for viral structures separations. HPLC columns based on CIM monolithic chromatographic supports are not only able to determine the ratio of full/empty viral capsids but can further separate and analyse subpopulations of the capsids.

4:00 Refreshment Break

PROCESS DEVELOPMENT STRATEGIES FOR OTHER VIRUSES

4:15 Retroviral Vector Process Development for CAR T Applications

Paulo_FernandesPaulo Fernandes, Senior Scientist, Process Development, Autolus

While retroviral vectors are one of the preferred choices for stable gene expression, the manufacture of these vectors is still limited in titer and quality. This presentation will focus on the process development efforts at Autolus to manufacture retroviral batches in sufficient amounts and with the right quality attributes for T-cell transduction and engineering.

8:30 KEYNOTE PRESENTATION:
Considerations and Challenges When Establishing a New Manufacturing Facility

Lance_WeedLance Weed, Ph.D., Vice President, Operations, uniQure

Over the past four years, uniQure has invested more than $25 million in designing, constructing and equipping its 55,000-square foot facility with state-of-the-art laboratories and commercial-scale production capabilities. This presentation will discuss the challenges in establishing a new manufacturing facility from scratch, and what small companies should consider when deciding whether to build their own manufacturing capability or use contract manufacturing.

9:00 Manufacturing Considerations for AAV Gene Therapies

Reed_ClarkK. Reed Clark, Ph.D., Senior Vice President, Pharmaceutical Development, Dimension Therapeutics

This presentation will discuss our approaches for scalable manufacturing to inform late-stage manufacturing of AAV-based gene therapy products. Lessons learned in the development of mammalian-based production platforms will be highlighted and the necessary analytics to support efficient process development discussed.

9:30 Separation of Virus, VLP and Extracellular Particles

Alois_JungbauerAlois Jungbauer, Ph.D., Professor, Institute of Biotechnology, University of Natural Resources and Life Sciences (BOKU)

Downstream processing of enveloped bio-nanoparticles is very challenging due to biophysical and structural similarity between correctly assembled particles such as VLP, viruses, exosomes and contaminating vesicular particles are present in the feedstock. Direct capture by connective media or flow through chromatography are used in connection with linear gradient elution to separate the products from other vesicles. Also advanced analytics will be addressed to discriminate the different particles.

10:00 Networking Coffee Break

10:30 Formulation Development for AAV Gene Therapy Application

Tanvir_TabishTanvir Tabish, Head, Drug Product Development for Gene Therapy, Device and Combination Products, Shire

A set of formulations was screened. One was found to stabilize the AAV based product for at least 5 months when stored frozen, and for at least 4 months when stored at +5°C. No visible particles together with no significant loss of infectivity or total particle titre was observed. SDS-PAGE and SEC did not show significant chemical or physical degradation. Adsorption studies did not reveal any loss with contact materials.

11:00 Advantages and Challenges of Early Phase Clinical Manufacturing in an Academic Setting

Jan_VanderLooJohannes C.M. van der Loo, Ph.D., Director, Clinical Vector Core, The Raymond G. Perelman Center for Molecular and Cellular Therapies, Children’s Hospital of Philadelphia

The Clinical Vector Core at the Children’s Hospital of Philadelphia has manufactured pre-clinical- and clinical-grade AAV and lentivirus-based custom viral vector products in support of early phase clinical studies.
