What to look forward to in GaBI Journal, 2024, Issue 2

Issue 2 of Volume 13 of GaBI ­Journal starts with a Review Article by Paul et al., titled ‘Increasing adoption of quality-assured biosimilars to address access challenges in low- and middle-income countries’. The review focuses on treatment of non-communicable diseases as these disproportionately affect people living in low- and middle-income countries compared to high-income countries. Challenges…

Abstract:This paper examines the repercussions of recent quality and regulatory crises in Japan’s generic pharmaceutical sector, focusing on incidents involving Sawai Group Holdings (Sawai GHD) and other manufacturers. It provides a comprehensive analysis of the consequences stemming from lapses in good manufacturing practice (GMP) compliance, particularly highlighted by the case of teprenone capsules 50 mg…

Abstract:US Food and Drug Administration’s (FDA) current thinking on interchangeability has evolved since the legal designation was first created in 2010. Based on experience, FDA now acknowledges that clinical switching studies are not generally needed for the interchangeability designation as quality, safety and efficacy are established by biosimilarity already. Approval pathways for biosimilars and interchangeable…

First 2024 GaBI Journal issue highlights

It was with great pleasure that I assumed the role of Editor-in-Chief (EiC) of GaBI Journal in January of this year. Taking over the helm from Professor Philip D Walson is a considerable challenge; Phil’s excellent, thorough example will be very difficult to follow. My experience is restricted largely to biosimilars with which I have…

Abstract: Monoclonal antibodies and cell therapies play an increasingly significant role in anticancer therapy, but small molecules remain an essential part of combination chemotherapy. Despite the publication of many studies on the extended stability of small molecule preparations, not all licensed medicinal products and stability-determining factors are covered. Submitted: 26 April 2024; Revised: 9 May…
