  • How To Evaluate & Manage Safety Risks In Biopharma
    5/2/2022

    Safety risks can be described and modelled as cause-and-effect relationships using system risk structures. This article structures risks beginning with a defined danger or threat so they can be effectively understood and then managed. Examples include wearing protective gloves (as a simple risk) and handling antibody-drug conjugates (as a complex risk).

  • 2 (Major) Impediments To Faster Biopharmaceutical Product Development
    5/29/2020

  • Can Biosimilars Be The Bridge To More Widespread Continuous Bioprocessing?
    5/19/2020

    This article will examine the relationship between improved continuous manufacturing (CM) and biosimilar development, paying particular attention to the reasons why biosimilars are especially promising candidates for CM development and innovation.

  • 3 Keys To Realizing FDA’s Vision For CAR-T And Other ATMPs
    12/12/2019

    While cell therapy remains a very promising approach to developing much-needed new immunotherapies, significant challenges will have to be overcome in order to realize the FDA’s twenty-first century vision of making complex ATMPs widely and cost effectively available to patients.

  • Are Good Manufacturing Practices No Longer Good Enough?
    10/28/2019

    Janet Woodcock’s recent comment on the state of pharmaceutical development,“It’s not working…,” should not surprise anyone. Her continuation, “and, it won’t work in the future," is the more surprising, and particularly troubling statement. What must we change?
