For generic drug developers, receiving tentative approval (TA)  for an Abbreviated New Drug Application (ANDA) is a major milestone—but it is not the end of the regulatory journey. Moving from tentative approval to final FDA approval  requires careful planning, timely submissions, and technically compliant study data. To support applicants, the FDA has issued two complementary guidance documents: ANDA Submissions — Amendments and Requests for Final Approval to Tentatively App

Safety reporting is one of the most critical safeguards in clinical trials involving investigational drugs and medical devices. To ensure that safety information is collected, evaluated, and communicated effectively, the U.S. Food and Drug Administration (FDA) has issued two complementary guidance documents: Investigator Responsibilities — Safety Reporting for Investigational Drugs and Devices   (December 2025), and Sponsor Responsibilities — Safety Reporting Requirements and

Clinical trials are the foundation for understanding whether a medical product is safe and effective. However, for many years, clinical trial populations have not fully reflected the patients who ultimately use these products in real-world settings. To address this gap, the U.S. Food and Drug Administration (FDA) has issued two complementary guidance documents: Enhancing Participation in Clinical Trials — Eligibility Criteria, Enrollment Practices, and Trial Designs  (Decembe

Medicine shortages can have a direct and serious impact on patient care, healthcare systems, and public health across Europe. To strengthen coordination, improve visibility, and enable early action, the European Medicines Agency (EMA) has established the European Shortages Monitoring Platform (ESMP) . The ESMP is a central digital platform designed to support the prevention, identification, monitoring, and management of shortages of medicinal products across the EU and EEA.

Placing a medical device or in vitro diagnostic (IVD) on the UK market involves more than product design and manufacturing. Manufacturers must demonstrate regulatory compliance, engage effectively with regulators, and prepare for evolving post-market expectations. To support this, the UK government and the Medicines and Healthcare products Regulatory Agency (MHRA) have published a series of guidances and roadmaps that explain both current requirements and the future direction

Medical device regulation in the UK is designed to ensure that products placed on the market or manufactured for patient use are safe, effective, and appropriately controlled. While most manufacturers are familiar with the general requirements of the UK Medical Devices Regulations 2002 (UK MDR 2002), certain categories of devices and manufacturing scenarios are subject to additional, specific legal provisions. Two important MHRA guidance documents explain these areas in detai

Developing a new drug is a long, expensive, and complex process. To make drug development more efficient and scientifically robust, the U.S. Food and Drug Administration (FDA) encourages the use of Drug Development Tools (DDTs) . These tools help sponsors generate better data, make informed decisions, and reduce uncertainty during drug development. To support this, FDA has established formal Drug Development Tool Qualification Programs, described on the FDA website Drug Deve

As biosimilars and interchangeable biosimilars become an integral part of modern biologic therapy, promotional communications around these products require heightened regulatory care. To address recurring industry questions and reduce the risk of misleading claims, the FDA has issued the guidance Promotional Labeling and Advertising Considerations for Prescription Biological Reference Products, Biosimilar Products, and Interchangeable Biosimilar Products . Published in 12 Dec

Radiopharmaceuticals present unique quality challenges due to their radioactive nature, short shelf lives, and frequent need for on-site or near-patient preparation. To reflect scientific and technological advances since the original 2007 guideline, the European Medicines Agency has released the draft Guideline on quality of radiopharmaceuticals – Revision 2  for public consultation. Adopted by CHMP in December 2025, this revision provides updated expectations for quality doc

Modern medicines development increasingly sits at the intersection of advanced chemistry and genomic science. On one hand, synthetic peptides represent a fast-growing therapeutic class that bridges small molecules and biologics. On the other, pharmacogenomics is reshaping how medicines are developed, evaluated, and ultimately used in patients. Recognising these parallel advances, the European Medicines Agency (EMA) has recently published two key scientific documents: the Guid

Post-authorisation changes are an inevitable part of medicinal product lifecycle management, and stability data play a critical role in demonstrating that such changes do not compromise product quality, safety, or efficacy. To harmonise expectations across the EU, the European Medicines Agency has issued Revision 3 of the Guideline on stability testing for applications for variations to a marketing authorisation . Adopted in December 2025 and effective from January 2026, this

As FDA continues to modernize and digitize its medical device review infrastructure, the updated guidance eCopy Program for Medical Device Submissions  plays a central role in transitioning industry toward fully electronic submissions. The December 2025 revision, reflected in the attached document, expands the technical requirements, clarifies the interaction between the eCopy and eSTAR programs, and incorporates contemporary digital standards needed to support efficient, err

The FDA has released two important guidances addressing very different but equally critical domains of drug development: the " nonclinical safety evaluation of monospecific monoclonal antibodies " and the appropriate inclusion of " QTc Information in Human Prescription Drug and Biological Product Labeling " . While one guidance focuses on modernising preclinical toxicology expectations for biologics, the other ensures that cardiac electrophysiology risks are clearly and consi

Regulatory teams responsible for lifecycle management know that post-authorisation changes can quickly become complex, especially as products mature, manufacturing processes evolve, and emerging scientific data require frequent updates to quality and clinical documentation. To support consistent interpretation of EU Variation Regulation (EC) No 1234/2008, the European Medicines Agency (EMA) maintains an extensive Q&A document titled " Classification of Changes " —a practical

As the UK strengthens its regulatory framework for medical devices, the Medicines and Healthcare products Regulatory Agency (MHRA) outlines a clear system for sponsors intending to conduct clinical investigations. These investigations are essential for generating evidence on device performance and safety before market approval. The MHRA guidance, “ Clinical investigations for medical devices " : that provides a structured route that sponsors must follow before initiating any
