A-Gene Webinar Series

A-Gene Overview

ARM has spent nearly four years on a mission to answer the question “What is the biggest challenge to cell and gene CMC and how can ARM address it?”. Many of the hurdles to streamlined, cost effective manufacture of cell and gene therapy products derive from a lack of standardized methodologies and training around CMC programs. Borrowing from the ‘A-Mab’ model created for the monoclonal antibody sector, ARM members have produced a similar document titled A-Gene, a case study-based guide to integrating QbD principles in gene therapy CMC programs.

In conjunction with the A-Gene document, ARM will be hosting a seven-part live webinar series highlighting specific A-Gene chapters. These webinars will occur monthly until culminating in a half-day virtual workshop.

Upcoming A-Gene Webinars

Regulatory Considerations

Thursday, February 10, 2022 | 11am – 12pm ET

Alexandra Beumer Sassi, Ph.D., Pharm.D., Senior Director, Chemistry, Manufacturing and Controls, Voisin Consulting
Saroj Ramdas, Executive Director, CMC Regulatory, Amicus Therapeutics
This webinar will discuss the regulatory frameworks in the United States, European Union and Japan. It will also provide guidance to sponsors on the best practices and recommendations in managing manufacturing changes during early development by establishing basic concepts in comparability appropriate for gene therapy products.

Downstream Processing

March, 2022 | Date and Time TBD

Danielle Ladwig, Senior Scientist I, Voyager Therapeutics
This webinar will discuss the commercial manufacturing process for downstream purification and how the Quality by Design (QbD) approach is a more systematic, goals-focused approach that leverages both historical knowledge and results through experimental design (DOE) and utilizes quality risk management during the development cycle.

A-Gene Case Study Virtual Workshop

June, 2022 | Date and Time TBD

Join ARM for a half-day virtual workshop focusing on the best practices for the gene therapy sector put forth in the A-Gene document.

Past A-Gene Webinars

Process Development Using Quality by Design (QbD) Principles

Jessie Sun, Ph.D., Director, Upstream Process Development, Pharmaceutical Development, Ultragenyx Gene Therapy
James Warren, Ph.D., Vice President, Pharmaceutical Development, Ultragenyx Gene Therapy
This webinar discusses process development and how it aims to establish and characterize a manufacturing process that can be scaled up to manufacture-size batches while continuing to yield a consistent, quality product. Various risk-based approaches are utilized to ensure that the process stays within appropriate limits and meets all safety and quality benchmarks.

Process Control Strategy

Althea Micklewright, Director, PSQA Business Excellence Lead, Pfizer
Iryna Sanders, Ph.D., Senior Principal Scientist, Pfizer
This webinar discusses how a comprehensive control strategy for pharmaceutical products – including gene therapies – is the key to achieving process consistency, product quality, safety, and efficacy. The speakers describe the approaches to developing a comprehensive control strategy and provide an overview of the key elements of a control strategy for a gene therapy product.

Upstream Processing

Shamik Sharma, Ph.D., Director, Molecular Biology and Upstream Process Development, Voyager Therapeutics
This webinar discusses the process overview of the upstream production of an AAV vector using an HEK 293 cell line. The speaker describes the Quality by Design (QbD) approach to process understanding and scaling.

A recording of this webinar will not be made available.


Drug Product

Jeffrey Hung, Ph.D., General Manager, Vigene Biosciences, a Charles River Company
This webinar discusses the vector manufacturing process and how it culminates with the formulation and vialing of the purified vector product. While this stage may come temporally at the end of the process, it is of the utmost importance to begin the gene therapy development process while considering the “end goal”. This webinar outlines the best practices for fill-finish, formulation, characterization, CCIT, and long-term storage and stability that can be used to develop a robust final gene therapy product.


Mo Heidaran, Ph.D., Vice President, Technical, Parexel International
This webinar provides guidance to sponsors and developers on the best practices and recommendations in managing manufacturing changes during early development by establishing basic concepts in comparability appropriate for gene therapy products, with a focus on adeno-associated virus (AAV)–based products.
